Abstract

Systems and methods for controlling the audio volume of an audio or audiovisual device are provided. In addition to making ordinary volume adjustments (i.e., changes to the "standard volume" setting), the disclosed systems and methods include a function for custom volume adjustment ("CVA"). The system/method can activate and deactivate the CVA function, for example using successive presses of a dedicated button or other command(s). Upon activation of CVA function, the system/method changes the device volume from its most recent standard volume setting (i.e., the volume just prior to activation) to a modified volume setting (i.e., "CVA setting"), which is a preset fraction of the most recent standard volume setting. Upon deactivation of CVA function, the system/method restores the device volume back to the most recent standard volume setting. The CVA function can be activated by a remote control, by voice command, by touch command, or other input methods.

SYSTEM AND METHOD FOR VOLUME CONTROL IN AN AUDIO OR AUDIOVISUAL DEVICE

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to and/or benefit of U.S. Patent Application No. 16/672, 197, filed November 1, 2019, entitled SYSTEM AND METHOD FOR VOLUME

CONTROL IN AN AUDIO OR AUDIOVISUAL DEVICE (Atty. Dkt. No. LLVN60-34468), the specification of which is incorporated by reference herein in its entirety.

TECHNICAL FIELD

[0002] The following disclosure relates to systems and methods for volume control in an audio or audiovisual device.

BACKGROUND

[0003] Abrupt changes to the average volume (i.e., audio sound level) of an audio or audiovisual device can often be inconvenient or unwelcome to listeners/viewers (“users”). For example, television stations may play commercials at a louder average volume than the accompanying program in an attempt to attract viewer attention. A typical view response in such case is to mute the volume (i.e., set the volume to zero). However, when the volume is muted, the viewer cannot hear the audio content at all, and thus may miss an interesting or relevant message.

[0004] In other cases, the volume within a program may become abruptly louder, for example, when a battle unexpectedly breaks out or when dramatic music swells. A typical viewer response in this case is to rapidly and repeatedly press the “volume down” button to moderate the sound level. In still other cases, the volume with a program shifts repeatedly from relatively quiet (e.g., conversation scene) to relatively loud (e.g., action scene). A viewer in this scenario is repeatedly switching between rapidly pressing the “volume down” button to rapidly pressing the “volume up” button. This need for repeated pressing of the “volume down” and/or “volume up” button is time-consuming and inconvenient.

[0005] A need therefore exists, for a volume control system for an audio or audiovisual device that allows more convenient user response to abrupt changes in audio volume.

[0006] Various automated volume-leveling systems have been implements for audio and audiovisual devices. Such systems often rely on automated monitoring of volume levels and automated adjustment of the device volume level. Such automated systems are often ineffective do not adjust the sound level as desired by the user.

[0007] A need therefore exists, for a volume control system for an audio or audiovisual device that is simple to use and effective in adjusting audio volume to a desired level. SUMMARY

[0008] In one aspect thereof, an audio volume control system is provided for a television assembly, the television assembly having a main portion and a remote control portion. The main portion includes an audio speaker capable of producing an output sound volume (Vo_ut) within a predetermined range of audio volume levels, and the remote portion includes a volume up button, a volume down button, a mute button and circuitry for sending volume control signals to the main unit to incrementally increase Vo_ut when the volume up button is activated, to incrementally decrease Vo_ut when the volume down button is activated, and to set Vo_ut = 0 when mute button is activated. The audio volume control system comprises circuitry in a television assembly for storing a standard volume setting value (Vs), a volume fraction value (VF), where VF ¹ 0; and a volume control mode value. A Custom Volume Adjustment (“CVA”) button is disposed on a remote portion of the television assembly, the CVA button being distinct from a volume up button, a volume down button and a mute button. Each activation of the CVA button generates a CVA control signal. Each generation of the CVA control signal causes the circuitry for storing the volume control mode value to alternate the volume control mode value between a “Standard” value and a “Modified” value. When the volume control mode value is “Standard”, the output sound volume Vo_ut of the audio speaker on the main portion is set to Vo_ut= Vs, and when the volume control mode value is “Modified”, the output sound volume Vo_ut of the audio speaker on the main portion is set to Vo_ut= Vs x VF.

[0009] In one embodiment of the audio volume control system, the volume fraction value VF is greater than 0% and less than 100%.

[0010] In another embodiment, the volume fraction value VF stored in the circuitry can be changed by pressing buttons on the remote portion of the television assembly.

[0011] In another aspect thereof, a system for controlling audio volume of an audio or audiovisual device comprises an audio or audiovisual device including an audio speaker capable of producing sound within a range of volume levels and volume control circuity operatively connected to the audio speaker for selectively changing the volume level of the sound produced by the audio speaker to a selected volume level within the range of volume levels. A processor is operatively connected to the volume control circuitry to send volume control signals to the volume control circuitry for changing the selected volume level. An input/output interface for receiving user commands including Custom Volume Adjustment (“CVA”) commands is operatively connected to the processor for sending CVA control signals to the processor in response to receiving the CVA commands. Upon receipt of the CVA commands, the processor selectively activates and deactivates a CVA function in a predetermined manner. Upon activation of the CVA function, the processor sends volume control signals to the volume control circuitry to change the selected volume level of the device from a most recent standard volume setting to a modified volume setting that is a preset fraction of the most recent standard volume setting. Upon deactivation of the CVA function, the processor sends volume control signals to the volume control circuitry to change the selected volume level of the device back to the most recent standard volume setting.

[0012] Ever since the remote control was invented, there has been a need for a button (or the modem verbal command) that could quickly and efficiently alter the set volume of a respective program, especially during commercial breaks or the need for timely conversation in the room, etc. Clearly, the mute and previous channel buttons are crucial for an effective remote control, and it is possible that the proposed CVA button will likely become the most popular button on the remote control. The need to constantly regulate the TV and radio during increased volume commercial breaks is a huge hassle, so many users just hit the easily triggered mute button instead. In addition, some will prefer to increase the volume with the CVA to hear dialogue better during a program featuring a lot of explosive action, which generally isn’t desired to be set too loudly at the onset.

[0013] Advertisers, thus the cable companies and TV/radio networks will absolutely love the CVA function, as it will keep their advertisements front and center. In fact, after diminishing the volume with a CVA click, many popular commercials will be immediately clicked back to the full preset volume of the respective program to watch their favorite commercial at full volume. A win/win all the way around.

[0014] In one embodiment, the CVA commands result from pressing buttons on a remote control component.

[0015] In another embodiment, the CVA commands result from voice commands received by a microphone operatively connected to the input/output interface. [0016] In yet another embodiment, the preset fraction is a setting in a memory of the system that is not adjustable by the user.

[0017] In still another embodiment, the preset fraction is greater than 0% and less than 100%. [0018] In a further embodiment, the preset fraction is within the range from 45% to 55%.

[0019] In a yet further embodiment, the preset fraction is greater than 0% and less than 100% or greater than 100%.

[0020] In a still further embodiment, the preset fraction is selectively adjustable by the user. [0021] In another embodiment, the preset fraction is greater than 0 and less than 1.

[0022] In yet another embodiment, the preset fraction is greater than 0 and less than 1 or greater than 1.

[0023] In still another embodiment, the preset fraction is greater than 0% and less than 100%. [0024] In a further embodiment, the preset fraction is greater than 0% and less than 100% or greater than 100%.

[0025] In another aspect, a method is provided for controlling the audio volume of an audio or audiovisual device including an audio speaker capable of producing sound within a range of volume levels and volume control circuity operatively connected to the audio speaker for selectively changing the volume level of the sound produced by the audio speaker to a selected volume level within the range of volume levels. The method comprises receiving, using an input/output interface, user commands including Custom Volume Adjustment (“CVA”) commands, and sending CVA control signals in response to receiving the CVA commands, and receiving, using a processor operatively connected to the input/output interface, the CVA control signals. Upon receipt of the CVA commands, the processor is used to selectively activate and deactivate a CVA function in a predetermined manner. Upon activation of the CVA function, volume control signals are sent using the processor to the volume control circuitry to change the selected volume level of the device from a most recent standard volume setting to a modified volume setting that is a preset fraction of the most recent standard volume setting. Upon deactivation of the CVA function, volume control signals are sent using the processor to the volume control circuitry to change the selected volume level of the device back to the most recent standard volume setting.

[0026] In one embodiment, receiving the CVA commands for a first time period corresponding to a momentary button press user action alternately activates and deactivates the CVA function; receiving the CVA commands for a second time period corresponding to a button press and hold user action alternately activates and deactivates a CVA configuration function; and when the CVA configuration function is activated, the preset fraction can be changed.

[0027] In another embodiment, the CVA commands are received from a remote control component.

[0028] In yet another embodiment, when the CVA configuration function is activated, the preset fraction can be increased by pressing an “Arrow Up” button on the remote control component and the preset fraction can be decreased by pressing an “Arrow Down” button on the remote control component.

[0029] In still another embodiment, receiving the CVA commands comprises receiving spoken word signals from a user.

[0030] In another aspect, a system for controlling audio volume of a playback component for audio or audiovisual content is provided. The system comprises a playback component including an audio speaker capable of producing sound within a range of volume levels and volume control circuity operatively connected to the audio speaker for selectively changing the volume level of the sound produced by the audio speaker to a selected volume level within the range of volume levels. A content appliance is operatively connected to the playback component by a physical or wireless connection for supplying the playback component with audio or audiovisual content for playback and for controlling the output volume of the playback component. The content appliance includes a processor, second volume control circuitry operatively connected to the processor and an input/output interface for receiving user commands including Custom Volume Adjustment (“CVA”) commands and is operatively connected to the processor and the second volume control circuitry for sending CVA control signals to the processor in response to receiving the CVA commands. Upon receipt of the CVA commands, the processor selectively activates and deactivates a CVA function in a predetermined manner. Upon activation of the CVA function (i.e., “Modified” mode), the processor sends volume control signals to the second volume control circuitry to change the selected volume level of the playback component from a most recent standard volume setting to a modified volume setting that is a preset fraction of the most recent standard volume setting. Upon deactivation of the CVA function (i.e., “Standard” mode), the processor sends volume control signals to the second volume control circuitry to change the selected volume level of the playback component back to the most recent standard volume setting.

[0031] In one embodiment, the content appliance is one of a cable box for receiving content from an analog or digital cable network, a satellite box for receiving content from a satellite receiver, a streaming device for receiving content from a worldwide computer network, a MP3 player, a CD player, a DVD player, a Blue-Ray player, a cassette player or a vinyl record player.

[0032] In another embodiment, the content appliance selectively changes the output volume level of the playback component by sending supplemental control signals from the processor or second volume control circuitry of the content appliance by the physical or wireless connection to the volume control circuitry of the playback component..

[0033] In another embodiment, the content appliance selectively changes the output volume level of the playback component by selectively increasing or decreasing the audio signal sent from the content appliance by the physical or wireless connection to the volume control circuitry of the playback component.

[0034] In another aspect, a system for controlling audio volume of a playback component for audio or audiovisual content comprises a playback component and a smart speaker device. The playback component includes an audio speaker capable of producing sound within a range of volume levels, volume control circuity operatively connected to the audio speaker for selectively changing the volume level of the sound produced by the audio speaker to a selected volume level within the range of volume levels and a receiver for receiving volume control signals, the receiver being operatively connected to the volume control circuitry for notifying the volume control circuitry of the received volume control signals. The smart speaker device is operatively connected to a worldwide network, and includes a microphone for receiving a Custom Volume Adjustment (“CVA”) voice command from a user and a connection to an external application for sending the received CVA voice command to the worldwide network for parsing and for receiving a CVA instruction from the worldwide network corresponding to the parsed CVA voice command. The smart speaker device further includes a transmitter for sending volume control signals to the receiver of the playback component in response to the CVA instruction. Upon receiving a CVA voice command from the user, the smart speaker device sends the CVA voice command to the worldwide network for parsing. Upon receiving a CVA instruction from the worldwide network corresponding to the parsed CVA voice command, the smart speaker device directly controls the audio volume of the playback component by transmitting volume control signals from the transmitter to the receiver of the playback component.

[0035] In one embodiment, the volume control signals sent from the transmitter adjust the audio volume of the playback component until the audio volume received by the microphone from the audio speaker of the playback component reaches a predetermined level according to the CVA instruction.

[0036] In another embodiment, when the current standard volume setting is Vcs, the current volume fraction setting is V_F and the received CVA instruction corresponds to activate a CVA “Modified” mode, the smart speaker device uses the microphone to monitor the audio volume received from the audio speaker of the playback component and the smart speaker device repeatedly sends “volume down” control signals from the transmitter to the receiver of the playback component until the audio volume from the playback component reaches a value V_Ms, where VMS = Vcs x VF.

[0037] In another embodiment, when the current standard volume setting is Vcs and the received CVA instruction corresponds to activate a CVA “Standard” mode, the smart speaker device uses the microphone to monitor the audio volume received from the audio speaker of the playback component and the smart speaker device repeatedly sends “volume up” control signals from the transmitter to the receiver of the playback component until the audio volume from the playback component reaches the value Vcs·

DETAILED DESCRIPTION

[0045] Referring now to the drawings, wherein like reference numbers are used herein to designate like elements throughout, the various views and embodiments of a system and method for volume control in an audio or audiovisual device are illustrated and described, and other possible embodiments are described. The figures are not necessarily drawn to scale, and in some instances the drawings have been exaggerated and/or simplified in places for illustrative purposes only. One of ordinary skill in the art will appreciate the many possible applications and variations based on the following examples of possible embodiments.

[0046] Referring now to FIG. 1, in one exemplary embodiment, an audio volume control system 100 is provided for a television assembly, the television assembly having a main portion 102 and a remote control portion 104. The main portion 102 includes an audio speaker 108 capable of producing an output sound volume (Vo_ut) within a predetermined range of audio volume levels. The remote portion 104 includes a volume up button 114a, a volume down button 114b, a mute button 114c and circuitry (FIG. 2) for sending volume control signals 112 to the main unit 102 to incrementally increase Vo_ut when the volume up button is activated, to incrementally decrease Vo_ut when the volume down button is activated, and to set Vo_ut = 0 when mute button is activated. The audio volume control system 100 further comprises circuitry (FIG. 2) in the television assembly for storing a standard volume setting value (Vs), a volume fraction value (VF), where VF ¹ 0; and a volume control mode value. A Custom Volume Adjustment (“CVA”) button 114d is disposed on a remote portion 104 of the television assembly, the CVA button being distinct from the volume up button 114a, the volume down button 114b and the mute button 114c. Each activation of the CVA button 114d generates a CVA control signal. Each generation of the CVA control signal causes the circuitry (FIG. 2) for storing the volume control mode value to alternate the volume control mode value between a “Standard” value and a “Modified” value. When the volume control mode value is “Standard”, the output sound volume Vo_ut of the audio speaker 108 on the main portion 102 is set to Vo_ut= Vs, and when the volume control mode value is “Modified”, the output sound volume Vo_ut of the audio speaker on the main portion is set to

Vo„t= Vs x V_F. [0047] For example, in the embodiment described above, the volume fraction value V_F can be set to 25% and the standard volume seting Vs can be set to a value of 80. Before activation of the CVA buton 114d, the volume control mode value is “Standard,” so the volume output Vo_ut from the speaker 108 will be at value 80 (i.e., the current value of Vs). Upon pressing the CVA buton 114d once (e.g., when a commercial starts), the volume control mode value is alternated to “Modified”, such that the volume output from the speaker 108 will now be set to Vo_ut= Vs x VF, which in this case is a value 40 (i.e., 80 x 25% = 20). Upon pressing the CVA buton 114d once more (e.g., when a commercial ends and the program resumes), the volume control mode value is alternated back to “Standard,” such that the volume output from the speaker 108 will now return to Vo_ut= Vs which in this case is a value 80. In this way, the volume can be conveniently changed with the press of a single buton (i.e., CVA buton 114d), from the current set volume to a modified volume that is a preset fraction of the set volume, and then returned to the original set volume with one additional press of the CVA buton. It will be understood that the standard volume up and volume down butons 114a, 114b can be used to change the standard volume seting Vs at any time. It will be further understood that the standard mute buton 114c can be used to change the standard volume seting Vs to zero at any time, thus allowing the mute buton to function identically regardless of the volume control mode seting.

[0048] With the volume control system 100, the user will not have to make many successive pushes of the volume down buton 114b to quickly reduce the output volume (e.g., when a commercial starts) and then make many successive pushes of the volume up buton 114a to return the output volume to the original level (e.g., when a commercial ends and the program resumes) as in television assemblies not having the volume control system.

[0049] In some embodiments of the volume control system 100 for a television assembly, the volume fraction value V_F is greater than 0% and less than 100%. This allows volume control system 100 to provide the widest range of volume reduction. In other embodiments, however, the, the volume fraction value VF can be greater than 100%. When the volume fraction value V_F is greater than 100%, then activation of the VC A buton 114d will result in a preset output volume increase instead of a decrease. Such control behavior can be useful when listening to content that has periodic “low volume” passages that the user wishes to hear more clearly. For example, the volume fraction value V_F can be set to 125% and the standard volume seting Vs can be set to a value of 60. Before activation of the CVA buton 114d, the volume control mode value is “Standard,” so the volume output Vo_ut from the speaker 108 will be at value 60 (i.e., the current value of Vs). Upon pressing the CVA button 114d once (e.g., when a quiet passage starts), the volume control mode value is alternated to “Modified”, such that the volume output from the speaker 108 will now be set to Vo_ut= Vs x VF, which in this case is a value 40 (i.e., 60 x 125% = 75). Upon pressing the CVA button 114d once more (e.g., when the quiet passage ends), the volume control mode value is alternated back to “Standard,” such that the volume output from the speaker 108 will now return to Vo_ut= Vs which in this case is a value 60.

[0050] In some embodiments of the volume control system 100 for a television assembly, the volume fraction value VF is preset and cannot be changed by the user. In other embodiments, the the volume fraction value VF can be changed by pressing buttons on the remote portion 104 of the television assembly.

[0051] Although the use of a volume control system for a television assembly has been described, in another aspect, a system for controlling the audio output volume (i.e., output sound pressure) produced by an audio or audiovisual device is described; and in particular, for controlling the output volume of the audio programming or content being delivered by the device, e.g., the music, television or movie soundtrack, video soundtrack, etc. In some embodiments, the audio or audiovisual device includes hardware that can produce output volumes (“Vo_ut”) at a plurality of volume levels (also known as values) within a volume range from a minimum volume level Vo_utMin to a maximum volume level Vo_utMax and further includes direct volume controls that can adjust the volume Vo_ut to a desired volume level within the volume range. In many embodiments, the minimum volume for the device is Vo_utMin = 0, i.e., no output volume / no sound pressure; however in other embodiments Vo_utMin can be any volume level that is less than Vo_utMax· In some embodiments, the direct volume controls include a volume increase control and a separate volume decrease control, wherein activation of the volume increase control changes Vo_ut from the current volume level (i.e., the volume level at the time of control activation) to a higher volume level and wherein activation of the volume decrease control changes Vo_ut from the current volume level to a lower volume level.

[0052] In some embodiments, the audio or audiovisual device hardware can produce output volumes Vo_ut(n) at a plurality of N discrete volume levels n, where n = (1...N) that are evenly distributed at increments within a range from the minimum audio volume Vo_ut(i) = Vo_utMin to the maximum audio volume Vo_ut(N) = Vo_utMax· In some embodiments, the direct volume controls include an incremental volume increase control and a separate incremental volume decrease control, wherein each activation of the incremental volume increase control changes Vo_ut from the current volume level to the next incrementally higher volume level, e.g., from Vo_ut(n) to Vo_ut(n+i), until Vo_utMax is reached, and wherein each activation of the incremental volume decrease control changes Vo_ut from the current volume level to the next incrementally lower volume level, e.g., from Vo_ut(n) toVo_ut(n-i₎, until Vo_utMin is reached. In some embodiments, the direct volume controls can be physical buttons or virtual buttons (e.g., on a touch screen) disposed on the audio or audiovisual device or on a remote control unit adapted to operate the device. For example the incremental volume increase control can be a physical or virtual button with markings such as, but not limited to, “UP” or “+” or “A” and the incremental volume decrease button can be a physical or virtual button with markings such as, but not limited to, “DOWN” or “DN” or “-” or “v” In some embodiments, the direct volume controls can be voice recognition circuitry comprising the audio or audiovisual device or the remote control unit adapted to operate the device. For example the incremental volume increase control can be voice recognition circuitry recognizing a user command such as, but not limited to, “Volume Up” or “Increase Volume” or “Louder” and the incremental volume decrease control can be voice recognition circuitry recognizing a user command such as, but not limited to, “Volume Down” or “Decrease Volume” or “Softer”.

[0053] Unless otherwise indicated herein, the term “standard volume range” means the range of audio output volumes or sound pressures that an audio or audiovisual device can produce when controlled by the direct volume controls. As described herein, the direct volume controls are the controls that are accessible by the user when the device is in a standard content delivery mode, e.g., while listening to a music program, watching a television show, watching a movie or video, etc. The direct volume controls can be distinguished from secondary volume controls, which are not accessible by the user when the device is in the standard content delivery mode, but rather are accessible to the user from special operating modes such as, but not limited to, a setting page, a setup screen, an on screen menu, etc. For example, some audio or audiovisual devices (e.g., iPhone, iPad and other iOS devices), include a secondary volume control known as “volume limit adjustment” that allows a user to set the maximum volume level that is accessible from the direct volume controls while the device is operating in a music playback mode, i.e., Vo_{utMax(iimited)}, that is a lower value than the inherent Vo_utMax capable by the device. For example, in iOS version 12.2, the volume limit adjustment secondary volume control is accessed from “Settings>Music>Volume Limit” and then adjusting a slider to select the level for Vo_{utMax(iimited)}· Before activating the volume limit adjustment, the iPhone’s direct volume controls can change the output volume over the range from 0 to Vo_utMax during music playback. After activating the volume limit adjustment, the iPhone’s direct volume controls can change the output volume over the range from 0 to Vo_utMaxfli_mited) during music playback. Thus, for the example iPhone device, when the volume limit adjustment is not activated, the standard volume range of the device is considered to be from 0 to Vo_utMax during music playback, whereas when the volume limit adjustment is activated, the standard volume range of the device is considered to be from 0 to Vo_utMaxfli_mited) during music playback.

[0054] In addition to making ordinary volume adjustments (i.e., changes to the “standard volume” setting), the disclosed volume control system includes a function for custom volume adjustment (“CVA”). The volume control system can activate and deactivate the CVA function, for example using successive presses of a dedicated CVA button or other dedicated CVA command(s). Upon activation of the CVA function, the volume control system changes the audio volume of the device from its most recent standard volume setting (i.e., the volume setting just prior to activation of the CVA function) to a modified volume setting (i.e., “CVA setting”), which is a preset fraction of the most recent standard volume setting. Upon deactivation of the CVA function, the system restores the audio volume of the device back to the most recent standard volume setting. In typical embodiments, the standard volume setting and the CVA preset fraction setting can be changed independently of one another. The CVA function can be activated by use of a remote control, by voice command, by touch command, or other input methods.

[0055] For convenience, the disclosed volume control system is first described as implemented in a remotely controllable television system; however, the system is not limited to control of televisions. Rather, the volume control system with CVA function can be implemented in any audio or audiovisual device including, but not limited to, televisions, radios, stereos, smart speakers, connected speakers, smart home connectivity devices (e.g., Amazon® Echo®, Google® Home), flat panel displays, computer displays, DVR devices, streaming content devices, DVD players, Blu-ray players, smart phones, smart pads, mobile devices, and smart (audiovisual) chat devices. In some embodiments, certain elements of the volume control system can be incorporated into a physical remote control component that is separate from the main audio or audiovisual device being controlled. In other embodiments, the volume control system can be entirely incorporated into the audio or audiovisual device being controlled. In some embodiments, the CVA function can be activated by sensing user voice, motion or touch with the audio or audiovisual device being controlled.

[0056] Referring again to FIG. 1, the illustrated audiovisual playback system incorporating the volume control system 100 with CVA function is described in further detail. The volume control system 100 of the illustrated embodiment can include a television set component 102 and a remote control component 104. In other embodiments, a different playback component 102' can be substituted for the television set component 102, and the system can operate in a substantially identical manner. The playback component 102' can be any type of component for playing audio or audiovisual content to a user. The television set component 102 (or playback component 102') can include a display screen 106, one or more audio speakers 108 and a remote control receiver 110 for receiving signals 112 from the remote control component 104. The signals 112 can be, but are not limited to, radio frequency (“RF”) signals, infrared (“IR”) light signals, ultrasonic audio signals or other control signals generated by the remote control component 104. In some embodiments, the television set component 102 can further include a microphone 113 for receiving voice commands relating to the CVA function. The remote control component 104 includes a plurality of buttons 114 for inputting control commands, including a volume up button 114a, volume down button 114b and a mute button 114c. In the illustrated embodiment, the remote control component 104 includes a dedicated button 114d for use with the CVA function. In some embodiments, the remote control component 104 can include a microphone 116 for receiving voice commands relating to the CVA function. In some embodiments, the remote control component 104 can be a dedicated device included as an accessory with the television set component 102, whereas in other embodiments, the remote control component can be a separately -purchased remote control (often known as a “universal” remote control) that is programmable for use with various devices from different suppliers.

[0057] Referring now to FIG. 2, there is illustrated a schematic system diagram of the television system 100. The television set component 102 can include a processor 210, a memory 212, a volume control circuit 214 and an input/output interface (“I/O interface”) 216, all of which can be operatively connected via a bus 218. The I/O interface 216 can receive control signals 112 from the remote control component 104 (e.g., via the remote control receiver 110) and/or from the user (e.g., via the microphone 113) and send corresponding signals to the processor 210 via the bus 218. The processor 210 can execute command sequences and store/retrieve values and/or program steps from the memory 212 via the bus 218. The volume control circuit 214 can receive volume control signals from the processor 210 via the bus 218 and is operatively connected to the speakers 108 to control the audio output volume of the television set component 102 within a range of volume levels in accordance with the volume control signals received from the processor. Elements and features of the volume control system and method can be implemented in circuitry of the processor 210, memory 212, volume control circuit 214 and/or I/O interface 216 and/or in program steps and values stored in the memory 212.

[0058] In some embodiments, the volume control circuit 214 of the television system 100 can control the audio output volume of the television set component 102 in accordance with volume control signals received from the processor 210. The volume control circuit 214 can control the speakersl08 to produce output volumes Vo_ut(n) at a plurality of N discrete volume levels n, where n = (1...N) that are evenly distributed at increments within a range from a minimum audio volume Vo_ut(i) to a maximum audio volume Vo_ut(N)· In some embodiments of the television system 100, the processor 210 can selectively generate incremental volume increase control signals and incremental volume decrease control signals in response to receiving certain signal patterns from the I/O interface 216. In some embodiments, the signal pattern received by the I/O interface 216 can be light, radio or sound signals produced by the remote control component 104 and received by the remote control receiver 110. In other embodiments, the signal patterns received by the I/O interface 216 can be voice commands issued by a user and received by the microphone 113. If the signal pattern received by the processor 210 from the I/O interface 216 corresponds to a volume increase pattern, the processor 210 can generate an incremental volume increase control signal and send the generated control signal to the volume control circuit 214 via the bus 218. If the signal pattern received by the processor 210 from the I/O interface 216 correspond to a volume decrease pattern, the processor 210 can generate an incremental volume decrease control signal and send the generated control signal to the volume control circuit 214 via the bus 218. Each time an incremental volume increase control signal is received from the processor 210, the volume control circuit 214 can increase the output volume Vo_ut(n) from the current volume level to the next incrementally higher volume level , e.g., from Vo_ut(n) to Vo_ut(n+i), until Vo_ut(N) is reached (at which point, no further volume increase occurs), and each time an incremental volume decrease control signal is received from the processor, the volume control circuit can incrementally decrease the output volume Vo_ut from the current volume level to the next lower volume level, e.g., from Vo_ut(n) toVo_ut(n-i₎, until Vo_ut(i) is reached (at which point, no further volume decrease occurs).

[0059] The remote control component 104 can include a processor 220, a memory 222, an I/O interface 226 and an input button interface 227, all of which can be operatively connected via a bus 228. In the illustrated embodiment, the remote control component 104 further includes a microphone 229 (substantially similar to microphone 116 of FIG. 7) operatively connected to the bus 228. In other embodiments, the microphone 229 may be connected to the I/O interface 226. The input button interface 227 can receive input indications from the user via the buttons 114 (e.g., buttons 114a - 1141) and send corresponding signals (including volume up/down control signals and CVA activate/deactivate control signals) to the processor 220 via the bus 228. In other embodiments, the buttons 114 can be operatively connected to the I/O interface 226 rather than to the bus 228. The microphone 229 can receive voice commands from the user and send corresponding signals (including volume up/down control signals and CVA activate/deactivate control signals) to the processor 220 via the bus 228. The processor 220 of the remote control component 104 can receive control signals from the input button interface 227 and/or microphone 229 via the bus 228 or the I/O interface 226 and can execute command sequences and store/retrieve values and/or program steps from the memory 222 via the bus 228. In response to executing program steps, the processor 220 can send volume control signals (including volume up/down control signals and CVA activate/deactivate control signals) to the I/O interface 226 via the bus 228. In response to receiving control signals from the processor 220, the I/O interface 226 can send control signals 112 (including volume up/down control signals and CVA activate/deactivate control signals) to the receiver 110 on the television set component 102, for example, using an infrared, optical or radio transmitter or transceiver (“TX/RX”) 230. Elements and features of the volume control system and method can be implemented in circuitry of the processor 220, memory 222, I/O interface 226, input button interface 227, microphone 229 and/or transceiver 230 and/or in program steps and values stored in the memory 212. [0060] In some cases, the volume control system with CVA function can be implemented in the audio or audiovisual device alone; however, in other cases such as the illustrated embodiment, a first portion the volume control system is implemented in the audiovisual device (i.e., the television set component 102) and a second portion of the volume control system is implemented in a secondary device (i.e., the remote control component 104). Specifically, in the illustrated embodiment, the first portion of the volume control system is implemented as program steps and/or circuitry in the processor 210, memory 212, volume control circuit 214 and/or I/O interface 216 of the television set component 102, and the second portion of the volume control system is implemented as a dedicated button 114d and/or microphone 229 on the remote control component 104 along with program steps and/or circuitry in the processor 220, memory 222, I/O interface 226 and/or input button interface 227 of the remote control component. In the illustrated embodiment, the dedicated button 114d is marked “CVA” denoting “Custom Volume Adjustment”; however, other markings can be used in other embodiments.

[0061] The volume control system 100 of the illustrated embodiment can be operated by pressing the dedicated button 114d (the “CVA button”). In some embodiments, the volume control system 100 can be operated (either alternatively to, or in addition to the CVA button 114d) by a voice command (the “CVA command”) received by the microphone 116, 113 or 229 on the remote control component 104 or on the television component 102, wherein receiving the CVA command has the same effect as pushing the CVA button. A volume fraction value V_F is stored in a system memory, typically in the memory 212 of the television set component. The volume fraction value V_F is a number that represents the system’s preset amount of volume modification. The volume fraction value V_F can be provided in percent, in decimal fraction or in any system representing anon-zero, fractional portion of the device’s volume range. For example, in one embodiment, the volume fraction value V_F can be a decimal fraction value between 0.00 and 1.00, and in a second embodiment, the volume fraction value V_F can be a percent value between 0% and 100%.

[0062] The volume fraction value V_F is not limited to decimal fractions between 0.00 and 1.00, or a percent value between 0% and 100%, but can also include fractions having a value greater than 1.00 (sometimes called improper fractions), or percentages greater than 100%. Whereas V_F values between 0.00 and 1.00 result in a reduction of device volume when the CVA function of the volume control system is activated, V_F values greater than 1.00 result in an increase of device volume when the CVA function is activated. In some cases, users may wish to use the CVA function to selectively increase the audio volume from the standard setting, for example, during quiet dialogue passages of a movie. For example, by setting the VF value to 1.20 (or 120%), activation of the CVA function would cause the device volume setting to increase by 20%, i.e., become 20% louder than the most recent standard volume setting.

[0063] Referring now also to Table 1, a further description of the current embodiment is provided. When the CVA button 114d is pressed or the CVA command is received with the system mode set to “Standard,” the CVA function is activated, for example, the volume control system retrieves the current system volume (Vcs) (i.e., the most recent standard volume setting) and the volume fraction value V_F from memory, determines a modified volume setting (V_Ms) using V_Ms = Vcs x VF, sets the device volume to VMS, and changes the system mode to “Modified.” When the CVA button 114d is pressed or the CVA command is received with the system mode set to “Modified,” the CVA function is deactivated, for example, the volume control system retrieves the most recent standard volume setting Vcs, sets the device volume back to Vcs, and changes the system mode to “Standard.” Thus, each time the dedicated CVA button 114d is pressed or the CVA command is received, the volume control system “toggles” between the Standard mode and the Modified mode. The Standard mode leaves the device at the most recent standard volume set by the user and the Modified mode immediately changes the device volume to a preselected fraction of the most recent standard volume setting.

[0064] In some embodiments, the volume fraction value V_F can be a fixed value that is set (e.g., in the factory) and not adjustable by the user. For example, in some embodiments, the volume fraction value V_F is factory preset to a number greater that 0% and less than 100% and not user adjustable. In some other examples, the volume fraction value V_F is factory preset to a number greater that 45% and less than 55% and not user adjustable. In some further examples, the volume fraction value VF is factory preset to 50% and not user adjustable.

[0065] In other embodiments, the volume control system 100 includes an initial preset volume fraction value VF and the user can subsequently adjust the value of VF up or down as desired. For example, in one embodiment, the volume control system 100 can have an initial value V_F set in the factory and can be configured in a V_F “Set mode” (or “Configuration mode”) by pressing and holding the CVA button 114d until a “Set mode” indication is given. The “Set mode” indication can be any type of user-perceivable indication including a sound or light flash, but in typical embodiments the “Set mode” indication is an on-screen display on the screen 106 of the audiovisual device. When the volume control system 100 is configured in “Set mode” the user can adjust the value of the volume fraction value V_F (e.g., using the “arrow up” button 114e and the “arrow down” button 1141) and store it in the system memory 212 or 222, e.g., by exiting “Set mode”. The next time the CVA mode is activated, the new value of V_F will be used to calculate the modified volume setting for the device.

[0066] Table 1 illustrates an exemplary sequence of actions to adjust the volume of an audiovisual device using one embodiment of disclosed volume control system 100, including activating the CVA system (i.e., change system mode to “Modified”) to set the device volume to a preset fraction of the most recent standard volume setting (steps 302, 308 and 316), deactivating the CVA system (i.e., change system mode to “Standard”) to return to the device volume to the most recent standard volume (steps 303, 311 and 317), making “ordinary” volume changes, i.e., changes to the standard volume setting (steps 304-307), activating ordinary mute and unmute functions (steps 309 and 310), entering “Set mode” (step 312), adjustment of the preset value of the volume fraction value V_F (steps 313-314) and exiting “Set mode” (step 315).

Table 1

[0068] For purposes of illustration, in the embodiment of Table 1 each press of the volume up/down button 114a/l 14b changes the standard volume setting by increments of 10, and each press of arrow up/down button 114e/l 14f changes the volume fraction value by increments 0.1; however, other increments can be used in other embodiments. In addition, in the embodiment of Table 1, the system enters and is subsequently released from CVA configuration mode by pressing and holding the CVA button; however, other embodiments may use different buttons or button-press patterns and/or voice commands to enter/release the configuration mode. [0069] In some embodiments of the volume control system 100, activation of the mute button 114c by the user does not affect the system mode nor activate the volume control system, i.e., the device volume simply goes to zero when muted, and returns to the most recent volume when “unmuted.” In other embodiments, however, activation of the mute button to “unmute” the device can cause the device volume to return to most recent standard volume setting and reset the system mode of the volume control system 100 to “Standard.”

[0070] In some embodiments of the volume control system 100, the CVA function can be activated by using voice commands received by a microphone 113, 116 or 229. The microphone can be disposed in a remote control component 104 or disposed within the audio or audiovisual device 102 to be controlled. In still other embodiments of the system 100, the microphone can be disposed in a separate device (“separate interface device”), for example, smart speakers, connected speakers, smart home connectivity devices (e.g., Amazon®

Echo®, Google® Home), smart phones, smart pads or mobile devices that constitute elements of the volume control system and can interface with the remote component 104 or audio or audiovisual device 102 to be controlled. In still other embodiments of the volume control system 100, the CVA function can be activated by using touch, touchscreen, tablet, keyboard and/or mouse commands received directly by the audio or audiovisual device or by a separate interface device incorporating the volume control system as previously described.

[0071] Referring now to FIGS. 3 and 4, in another aspect, methods for controlling the audio volume of an audiovisual device are described. In addition to making ordinary volume adjustments (i.e., changes to the “standard volume” setting), the disclosed volume control method includes a function for custom volume adjustment (“CVA”). The volume control method can activate and deactivate the CVA function, for example in response to receiving successive presses of a dedicated CVA button or other dedicated CVA command(s). Upon activation of the CVA function, the volume control method changes the audio volume of the device from its most recent standard volume setting (i.e., the volume setting just prior to activation of the CVA function) to a modified volume setting (i.e., “CVA setting”), which is a preset fraction of the most recent standard volume setting. Upon deactivation of the CVA function, the method restores the audio volume of the device back to the most recent standard volume setting. In typical embodiments, the method allows the standard volume setting and the CVA preset fraction setting can be changed independently of one another. The CVA function can be activated by use of a remote control, by voice command, by touch command, or other input methods.

[0072] Referring first to FIG. 3, there is illustrated a block diagram of a method 350 for implementing volume control of an audio or audiovisual device including a CVA function.

In the disclosed method 350, the controlled volume toggles between a standard volume setting and a modified (i.e., CVA preset fractional) volume setting. In block 352, the method detects receipt of a CVA toggle command. The CVA toggle command can result from the user pressing a dedicated button, e.g., CVA button 114d on the remote component 104, the user issuing a CVA voice command through a microphone 113, 116 or 229 on the remote component 104, on the controlled audio or audiovisual device 102, or on a separate interface device, or the user issuing the CVA command as otherwise previously described. In block 356, the method detects whether the CVA function mode is set to “Standard,” and if so, changes the device volume to a modified volume setting by steps 358, 360 and 362, and then changes the CVA function mode to “Modified” in block 364. Alternatively, if the method in block 356 detects the CVA function mode is not set to “Standard,” the method resets the device volume to the standard volume setting by step 366 and then changes the CVA function mode to “Standard” in block 368. After either step 364 or 368, the method returns to block 352 and waits for another CVA toggle command.

[0073] Referring now to FIG. 4, there is illustrated a block diagram of a method 400 for adjusting the volume fraction value V_F used by the CVA function.

[0074] Referring now to FIG. 5, there is illustrated an alternative volume control system 500 in accordance with another aspect. The volume control system 500 is similar in many respects to the volume control system 100 previously described in connection with, e.g.,

FIGS. 1 and 2. Only the elements that differ substantially from those described in FIGS. 1-2 are renumbered. The system 500 can include a playback component 102' and the remote control component 104. The playback component 102' can be the television set 102 as previously described or another type of audio or audiovisual playback device including, but not limited to, a video monitor with speakers, an audio amplifier with speakers, a home theater device, a sound bar device, a surround sound device and a wireless speaker device. The playback component 102' can include a speaker 108 remote control receiver 110 and/or microphone 113 similar to the television 102. Further, the playback component 102' can include a processor 210, a memory 212, a volume control circuit 214, an I/O interface 216 and a bus 218 as described in FIG. 2 that are configured to perform a CVA function upon receipt of CVA control signals from the user or from the remote control component 104 substantially as previously described in connection with FIGS. 1 and 2.

[0075] In addition to the playback component 102' and the remote control component 104, the volume control system 500 can include a separate content appliance 505 for supplying the playback component 102' with audio or audiovisual content for playback. In some embodiments, the content appliance 505 can receive the audio or audiovisual content from an external source. For example, in one embodiment, the content appliance 505 can be a so-called “cable box” or “set-top box” that receives audio or audiovisual content from an analog or digital cable network 520. In another embodiment, the content appliance 505 can be a “satellite box” that receives audio or audiovisual content from a satellite receiver 522. In still another embodiment, the content appliance 505 can be a “streaming device” or “dongle” that receives audio or audiovisual content from a worldwide computer network 524 such as the internet. Such streaming devices include, but are not limited to, an Apple® TV device, an Amazon® Fire TV device, a Google® Chromecast device, a Roku® Streaming Stick device and a Nvidia® Shield TV device. In further embodiments, the content appliance 505 can be a pre-recorded content playback device such as a MP3 player, a CD player, a DVD player, a Blue-Ray player, a cassette player or a vinyl record player. The content appliance 505 can be operably connected to the playback component 102' by a physical connection 526 (e.g., electrical cables, USB connector, optical fibers, etc.) and/or by a wireless connection 528 (e.g., WiFi, Bluetooth, etc.).

[0076] The content appliance 505 can include a remote control receiver 510 for receiving signals 512 from the remote control component 104. The signals 512 can be, but are not limited to, radio RF signals, IR light signals, ultrasonic audio signals or other control signals generated by the remote control component 104. In some embodiments, the content appliance 505 can further include a microphone 513 for receiving voice commands (i.e., verbal command signals) relating to the CVA function.

[0077] The content appliance 505 can also include CVA-related circuitry, namely, a processor 210, a memory 212, a volume control circuit 214, an I/O interface 216 and/or a bus 218 as described in FIG. 2 that are configured to selectively perform CVA functions upon receipt of CVA control signals from the user or from the remote control component 104 substantially as previously described in connection with FIGS. 1-4 and Table 1. In the system 500, however, the output of the volume control circuit 214 of the content appliance 505 is not directly connected to the speaker 108 of the playback component 102', but instead the content appliance can control the playback volume indirectly. In some embodiments, the CVA-related circuitry (e.g., the volume control circuitry 214) of the content appliance 505 can control the audio level of the playback component 102' by selectively modifying (i.e., reducing or increasing) the audio signal sent from the content appliance to the playback component via the I/O interface 216 and the connection 526 or 528. When the content appliance 505 includes the CVA-related circuitry of this type, the content appliance can provide the custom volume adjustment functionality to the system 500 even if the playback component 102' does not include its own CVA-related circuitry. In other words, when the content appliance 505 features the CVA-related circuitry, the custom volume control feature of the system 500 can be implemented regardless of whether the playback component 102' includes the CVA-related circuitry. In other embodiments, the CVA-related circuitry of the content appliance 505 (e.g., the processor 210 and/or the volume control circuit 214) can control the audio level of the playback component 102' by sending supplemental control signals directly to the volume control circuitry of the playback component via the physical or wired connection 526 or the wireless connection 528. In still other embodiments, wherein both the content appliance 505 and the playback component 102' include a respective set of CVA-related circuitry, the content appliance can control the audio level of the playback component by sending CVA control signals from the CVA-related circuitry (e.g., the processor 210 or the volume control circuitry 214) of the content appliance to the relevant CVA-related circuitry (e.g., the processor 210 or the volume control circuitry 214) of the playback component via the connection 526 or 528.

[0078] In some embodiments of the system 500, the remote control component 104 for controlling the content appliance 505 can be a remote control device specifically configured to work with the content appliance. In other embodiments, the remote control component 104 for controlling the content appliance 505 can be the same remote control component configured to operate with the television 102 or playback component 102'. In still other embodiments of the system 500, the remote control component 104 can be a universal remote that can be configured to work with both the playback component 102' and the content appliance 505. In yet further embodiments of the system 500 wherein both the content appliance 505 and the playback component 102' include their own respective set of CVA- related circuitry, a first remote control component 104' can be configured to work with the playback component 102' and a second remote control component 104" can be configured to work with the content appliance 505 such that the volume control function of the current system can be operated by use of either remote control component.

[0079] Operation and control of the custom volume control system 500 of FIG. 5 is substantially identical to the operations explained in FIG. 3 and FIG. 4 and Table 1.

[0080] Referring now to FIG. 6, there is illustrated an alternative volume control system 600 in accordance with another aspect. The volume control system 600 is similar in many respects to the volume control systems 100 and 500 previously described. Only the elements that differ substantially from those previously described are renumbered. The system 600 can include a playback component 102' and a smart speaker device 605 (sometimes known as a “home automation device” or “home hub device”), for example an Amazon® Echo® device or a Google® Home device, which is connected to the internet 524 or “cloud.” The smart speaker device 605 includes a microphone 607 for detecting ambient sounds including voice commands 610 from users. The smart speaker device 605 sends the voice commands 610 received from users through the connection 611 (which can be wired or wireless) to applications on the internet or cloud 524 for parsing. The smart speaker 605 then receives a response to the parsed user commands from the internet application, which response can be data or machine-level commands to take further action. The volume control system 600 can also include, but does not require, a remote control component 104 and a content appliance 505.

[0081] In the volume control system 600, the smart speaker device 605 can use the microphone 607 to receive a CVA voice command 610 from the user relating to a predetermined CVA function. The received CVA voice command 610 can be sent by the smart speaker device 605 to the internet or cloud 524 for parsing. In response to sending the CVA voice command, the smart speaker device 605 can receive a CVA instruction back from the internet application. The smart speaker device 605 can then execute the received CVA instruction by sending a CVA control signal 614 or 616 to the playback component 102' or content appliance 505, respectively, from a transmitter 612. If the CVA control signals 614 or 616 are RF signals, IR signals or ultrasonic signals, the transmitter 612 can send the control signals to the receiver 110 or 510, respectively, whereas if the CVA control signals are audio signals, the transmitter can send the control signals to the microphone 113 or 513, respectively. In some embodiments, the smart speaker device 605 can be programmed to mimic or emulate the function of a remote control component 104 that was originally sold with the playback component 102' or content appliance 505, thereby enabling the smart speaker device to replace or supplement the remote control component 104 in the previously described systems 100 or 500.

[0082] In some embodiments of the volume control system 600, at least one of the playback component 102' or the content appliance 505 (if present) includes the CVA-related circuitry including a processor 210, a memory 212, a volume control circuit 214, an I/O interface 216 and/or a bus 218 as described in FIG. 2 that are configured to perform a CVA function upon receipt of predetermined CVA control signals. The smart speaker device 605, upon receiving the relevant CVA voice command 610 from the user, sending the voice command for parsing and receiving the corresponding CVA instruction as previously described, can send the CVA control signals 614 or 616 to the playback component 102' and/or content appliance 505 in a manner substantially identical to the function of the remote control component 104 previously described in connection with FIGS. 1-4 and Table 1. In other words, the smart speaker device 605 can perform the CVA control signaling previously performed by the remote control component 104. In some embodiments, the remote control component 104 is still present and can still operate as an additional portion of the volume control system 600.

[0083] Referring still to FIG. 6, in another volume control system 600 according to an alternative aspect, it is not required that at least one of the playback component 102' or the content appliance 505 includes the CVA-related circuitry including a processor 210, a memory 212, a volume control circuit 214, an I/O interface 216 and/or a bus 218 as described in FIG. 2. In this alternative volume control system 600, the smart speaker device 605, upon receiving the relevant CVA voice command 610 from the user, can send the CVA voice command to the internet application for parsing, can receive the corresponding CVA instruction from the internet application as previously described, and can directly control the volume of the playback component 102' or content appliance 505 to implement the CVA instruction. The direct implementation of the CVA instruction by the smart speaker device 605 is performed by transmitting conventional volume control signals (e.g., volume increment up commands or volume increment down commands) to the playback component 102' or content appliance 505 using the transmitter 612, and then using the microphone 607 to monitor or “listen” to the audio volume of the sound 618 issuing from the speakers 108 of the playback component. In some embodiments, the steps of sending a control signal 614 or 616 using the transmitter 612 and monitoring the received volume 618 using the microphone 607 constitutes a closed-loop audio control system.

[0084] For example, when the alternative system 600 has a current playback volume setting Vcs, and the user commands the smart speaker device 605 to activate the CVA “Modified” mode, the smart speaker device can repeatedly issue conventional “volume down” control signals 614, 616 (e.g., mimicking the control signals of a remote control component 104) to the playback component 102' or content appliance 505 using the transmitter 612 until the sound volume 618 received by the microphone 607 from the playback component reaches the “modified setting”, V_Ms, where V_F is the CVA preset volume fraction and VMS = Vcs x VF, as previously described. As another example, when the user commands the smart speaker device 605 to set the system back to CVA “Standard” mode, the smart speaker device can repeatedly issue the conventional “volume up” control signals 614, 616 to the playback component 102' or content appliance 505 using the transmitter 612 until the monitored sound volume 618 received by the microphone 607 from the playback component reaches the original volume setting, Vcs· In this manner, the alternative volume control system 600 can be implemented using a suitably modified smart speaker device 605, even if the playback component 102' or content appliance 505 are conventional, i.e., without the special CVA-related circuitry.

[0085] It will be appreciated by those skilled in the art having the benefit of this disclosure that this system and method for volume control in an audio or audiovisual device provides a great convenience to users and a great improvement over the conventional art. It should be understood that the drawings and detailed description herein are to be regarded in an illustrative rather than a restrictive manner, and are not intended to be limiting to the particular forms and examples disclosed. On the contrary, included are any further modifications, changes, rearrangements, substitutions, alternatives, design choices, and embodiments apparent to those of ordinary skill in the art, without departing from the spirit and scope hereof, as defined by the following claims. Thus, it is intended that the following claims be interpreted to embrace all such further modifications, changes, rearrangements, substitutions, alternatives, design choices, and embodiments.
