Description

TITLE: SYSTEM AND METHOD FOR WIRELESS VOICE

ACTIVATION OF MOTORIZED WINDOW COVERINGS

FIELD OF THE INVENTION:

This invention relates to motorized window coverings. More specifically, and without limitation, this invention relates to a system and method for wireless voice activation of motorized window coverings.

BACKGROUND OF INVENTION:

Sound or voice activation of electronic devices is old and well known in the art. An early example of sound activation of an electronic device includes what is well known as "The Clapper®". The Clapper® is an electronic switch used to actuate electric appliances, such as a light or a TV, when two or three claps, separated by approximately half a second, are registered by a microphone in the device.

Later examples of using sound or voice activation of electronic devices exist in cell phone technology. As one example, Samsung's Galaxy HIS, includes an imbedded application that that listens for a trigger phrase, such as "Hello Galaxy", and thereafter enters into a voice command mode where the user can instruct the phone to call or text one of the contacts, search the internet for information, or perform any one of a number of other operations. Similarly, Apple's iOS (iPhone Operating System) has an application named Siri that uses a natural language user interface to answer questions, make recommendations, and perform actions by delegating requests to a set of Web services.

Another later example includes the Ford SYNC® system which similarly allows a user to make hands-free phone calls, select and play music, enter a destination using onboard navigation, request emergency assistance, send a text message, receive a vehicle status report, among other options, all while driving.

Motorized window coverings are also old and well known in the art, as is the electronic control of motorized window coverings through the use of switches, remote controls and the like. Despite the prior art electronic devices used to control motorized window coverings, deficiencies and problems remain in the prior art. In particular, these electronic control devices are inefficient, complicated, they are easy to lose, and they can cause delays in opening or closing motorized window coverings, especially when the electronic devices cannot be located. Never before has there been a voice activated system for

I controlling motorized window coverings that allows a user to accurately and precisely actuate one or more motorized window coverings using only their voice in an efficient, robust and easy to use manner.

Thus it is a primary object of the invention to provide a system and method for wireless voice activation of motorized window coverings that improves upon the state of the art.

Another object of the invention is to provide a system and method for wireless voice activation of motorized window coverings that is easy to use.

Yet another object of the invention is to provide a system and method for wireless voice activation of motorized window coverings that is intuitive.

Another object of the invention is to provide a system and method for wireless voice activation of motorized window coverings that is simple.

Yet another object of the invention is to provide a system and method for wireless voice activation of motorized window coverings that provides a plurality of ways to actuate the motorized window coverings.

Another object of the invention is to provide a system and method for wireless voice activation of motorized window coverings that is inexpensive.

Yet another object of the invention is to provide a system and method for wireless voice activation of motorized window coverings that allows for the activation of a plurality of window coverings simultaneously.

Another object of the invention is to provide a system and method for wireless voice activation of motorized window coverings that allows for grouping of a plurality of motorized window coverings.

These and other objects, features, or advantages of the present invention will become apparent from the specification and claims.

SUMMARY OF THE INVENTION:

A system for controlling at least one motorized window covering using wireless voice activation is presented. The system includes a voice activation module which is wirelessly connected to a plurality of motorized window coverings. The voice activation module is connected to a conventional power source within activation proximity of the motorized window coverings. The voice activation module is preprogrammed to listen for a trigger phrase followed by any one of a number commands. Once the trigger phrase and a command are recognized, the wireless device transmits an over-the-air signal to the plurality of motorized window coverings. These preprogrammed commands include Open, Close, Position 1 (such as 25% closed), Position 2 (such as 50% closed), Position 3 (such as 75% closed). The wireless device also includes at least one push-button that is configured, when manually activated, to transmit an over-the-air signal to open and/or close the motorized window coverings. The wireless device also includes an indicator that provides a visual or audible indication to the user that the trigger phrase, and/or a command has been recognized.

Also, while the term window coverings is used consistently throughout, this term too is not meant to be limiting and instead refers to any window covering such as a blind, shade, drapery or the like.

With reference to the Figures, a system 10 and method for wireless voice activation and control of motorized window coverings is presented.

Voice Activation Module: The system 10 includes a voice activation module 12 which is electronically connected to a power source 14. Power source 14 is any form electric power. In one arrangement, as is shown, power source 14 is a conventional AC wall outlet, into which voice activation module 12 is plugged. However any other form of electric power is hereby contemplated for use such as a battery system, a generator or the like. In an alternative arrangement, voice activation module 12 includes a power source 14 such as batteries 15 positioned within the voice activation module 12. In yet another arrangement, the voice activation module 12 is both battery powered, as well as capable of being plugged in to charge the batteries 15 and/or power the voice activation module 12. Voice activation module 12 is of any form, shape or design. In one example, as is shown, voice activation module 12 includes a main housing 16. In the arrangement shown, main housing 16 has a clamshell design having a forward half 18 connected at a seam line to a rearward half 20. Main housing 16 also includes electrical connectors 22 which, in one arrangement, extend outwardly from the rearward half 10 for insertion into a standard wall plug. A power control unit 24 is positioned within main housing 16 and serves to convert, meter and distribute the power received from power source 14 into the proper form and amount so as to power the components of voice activation module 12.

Main housing 16 includes a connection slot 26. Connection slot 26 is any slot, socket or connection device used to connect two electrical components such as a USB port, an Ethernet connection port, or the like. In the arrangement shown, a USB port is depicted as one example.

In one arrangement, electronic component 28 is removeably and replaceably connected to connection slot 26. In an alternative arrangement, electronic component 28 is permanently affixed to main housing 16. Electronic component 28 includes plug 30 and frame 32. Plug 30 is any form of a connection plug or connection device that is used to connect two electrical components such as a USB plug, Ethernet plug, or the like. In the arrangement shown, as one example, plug 30 is in the form of a USB port and serves to removeably and replaceably connect electronic component 28 to connection slot 26. Frame 32 is connected to plug 30. Frame 32 serves to connect and provide structural support and rigidity for the other components of electronic component 28 including PC board 34.

PC board 34 is any form of a printed circuit board ("PCB") or similar device used to mechanically support and electrically connect the electronic components of the device, as is described herein, using conductive pathways, tracks or signal traces etched into or connected to a non-conductive substrate. In one arrangement, PC board 34 and frame 32 are one and the same. In another arrangement, PC board 34 and frame 32 are independent units wherein the PC board 34 is connected to frame 32.

Cover 35 is positioned around the exterior of frame 32, electronic component 28 and PC board 34, with plug 30 extending outwardly therefrom. In the arrangement shown, cover 35 has a clamshell design having a front half 35A and a rearward half 35B connected together at a seam line. The front half 35A has designated openings therein for a microphone 36 and/or speaker 38 as well as buttons and indicators as is described herein. In one arrangement, when cover 35 is assembled around frame 32, electronic component 28 and pc board 34, the plug 30 can be removed from as well as inserted into connection slot 26. In this way, electronic component 28 is a stand-alone unit and can be used to plug into any USB plug. In another arrangement, once assembled, plug 30 cannot be removed from connection slot 26 thereby making a single unitary device.

Voice activation module 12 includes a microphone 36, and a speaker 38. Microphone 36 is any device which receives an acoustic signal, or sound, and converts it into an electronic signal. Microphones are commonly referred to as acoustic-to-electric transducers or sensors. Speaker 38 is any device which produces sound or an audible response. Speakers are commonly referred to as an electromechanical or electroacoustic transducer that produces sound in response to an electrical audio signal input. In one arrangement, microphone 36 and speaker 38 are independent stand-alone units. In another arrangement, microphone 36 and speaker 38 are combined into a single unit. Without limitation, hereinafter, microphone 36 and speaker 38 shall be collectively referred to as microphone 36 possessing the function of both receiving an audible signal (microphone) and sending an audible signal (speaker).

Microphone 36 receives and/or senses sound and voice commands, converts these sounds and voice commands to an electronic signal and transmits them to other components of voice activation module 12 as is described herein. Microphone 36 also transmits a sound acknowledgement or response when certain commands are received as is described herein.

In one arrangement, voice activation module 12 supports two way communication. In this arrangement, voice activation module 12 possess the ability to send electromagnetic or digital signals to a plurality of motorized window coverings, as well as possessing the ability to receive responsive signals from the plurality of motorized window coverings. To ensure the signals and/or commands have been received, understood and executed, thereby improving the effectiveness of the system 10. In a two-way communication arrangement, voice activation module 12 includes a transceiver 40, as well as a microprocessor 42 and memory 44. In a one-way communication arrangement, voice activation module 12 only requires a transmitter which transmits signals to other components of system 10 and not a transceiver which transmits and receives signals. The following description is directed towards two-way communication, with the understanding that one-way communication is hereby contemplated and supported by this disclosure by eliminating the two-way features (that is replacing the herein described transceivers with receivers). Transceiver 40 is any device which transmits and receives an electronic signal. In one arrangement, the sending and receiving functions of transceiver 40 are performed on common circuitry, whereas in an alternative arrangement, the sending and receiving circuitry is separate. Microprocessor 42 is any programmable device that accepts electronic signals or data as input, processes it according to instructions stored in memory 44, and provides results as output. In one arrangement, transceiver 40 transmits and receives an electromagnetic wave or electromagnetic signal in or around the range of 433 MHz radio wave, also known as radio frequency waves (RF), and/or uses AM or FM signals. In another arrangement, any other electromagnetic signal or frequency is used.

In one arrangement, microphone 36 picks up audible signals from its environment when these audible signals exceed a predetermined volume threshold, or meet predetermined characteristics, microphone 36 converts them to an electronic signal and transmits them to microprocessor 42. Microprocessor 42 processes these electronic signals according to instructions stored in memory 44. When microprocessor 42 receives a signal it recognizes as a command, it instructs transceiver 40 to transmit control signals via electromagnetic signals or electromagnetic waves to other components of system 10 through antenna 46.

Antenna 46 is any electronic device which converts electric power into

electromagnetic signals or electromagnetic waves, which are commonly known as radio waves or RF (radio frequency) (hereinafter collectively referred to as "electromagnetic signals" without limitation). In one arrangement these electromagnetic signals are transmitted via AM or FM RF communication, while any other range of RF is hereby contemplated. In one arrangement, antenna 46 transmits as well as receives electromagnet signals. In transmission, a radio transmitter (transceiver 40) supplies an oscillating radio frequency electric current to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic waves or electronic signals (radio waves). In reception, the antenna intercepts some of the power of an electromagnetic wave or electromagnetic signal in order to produce a tiny voltage at its terminals that is applied to a receiver/transceiver 40.

Voice activation unit 12 also includes an indicator 48. Indicator 48 is any device which provides a visual indication such as a light, LED, visual display or mechanical device. Indicator 48 provides the user with a visual indication of the status of the voice activation unit 12. As one example, if indicator 48 is a light, when the voice activation unit 12 is active the light is illuminated whereas when the voice activation unit 12 is inactive or asleep the light is not illuminated. As another example, if indicator 48 is a light capable of producing multiple colors, such that when a command is recognized the light is green, and when a command is not recognized the light is red. Alternatively, indicator 48 is an audible sound. In this way, indicator 48 provides the user with an instantaneous real-time visual indication of the status of voice activation unit 12.

Voice activation unit 12 also includes at least one activation button 50. In the arrangement shown, voice activation unit 12 includes an up button 50A which when manually activated or pressed, causes voice activation unit 12 to transmit a first command, such as an open command, and a down button 50B which when manually activated or pressed, causes voice activation unit 12 to transmit a second command, such as a close command. While only an up button 50A and a down button 50B are shown and explicitly described, any other number of buttons is hereby contemplated for use in association with voice activation unit 12.

Motorized Window Coverings: A plurality of motorized window coverings 52 are electronically connected to the system 10. Motorized window coverings 52 are formed of any suitable size, shape and design.

In one arrangement, as is shown, motorized window coverings 52 include a tube 54 with shade material 56 wrapped around the tube 54. Window coverings of this type are commonly known as "roller shades" such as those manufactured by QMotion Incorporated, which are the subject of a plurality of patents and patent applications which are fully incorporated herein by reference including any and all related continuation, continuation-in- part, divisional or other related applications including U.S. Patent No. 8,299,734 entitled "High Efficiency Roller Shade" filed on February 23, 2010, issued on October 30, 2012 with Application Serial No. 12/71 1 , 192; and U.S. Patent No. 8,368,328 entitled "Method Of Operating A Motorized Roller Shade" filed on February 23, 2010, issued on February 5, 2013 with Application Serial No. 12/71 1 , 193, among other related applications. When activated, window covering 52 rotates upon axis point 58 thereby wrapping or unwrapping shade material 56 around tube 54 thereby opening or closing the window covering 52 based on the direction of rotation. One improved feature of the QMotion motorized window coverings 52 is that they provide the ability to be battery powered, wirelessly controlled, moved by a motor as well as allowing for manual movement by a user merely by pulling the bottom bar 57. This manual movement of the motorized window coverings 52 is accomplished by under powering the motor of the shade (as one example, supplying less than 12 volts to a 24 volt motor). This causes the batteries to last a long time, the motor to run quietly, and the motor to rotate slowly. This allows the motor 78 to rotate with the shade tube 54. This arrangement allows for a manually movable window covering 52, a motorized window covering 52, as well as a window covering which is movable by the user's voice. In addition, QMotion window coverings 52 are also movable by tugging the bottom bar 57. Never before has a window covering 52 been offered that can be controlled in all of these manners.

In another arrangement, as is shown, motorized window coverings 52 include a drapery unit 60 with tube 54 having a helical feature 62 positioned on the exterior surface of the tube 54. In one arrangement, helical feature 62 includes a plurality of grooves; in another arrangement, helical features 62 include a plurality of threads. A plurality of connecting members 64 are positioned around drapery rod 60 and matingly engage helical features 62. Shade material 56 is connected to and hangs down from connecting members 64. In this arrangement, as tube 54 rotates around axis point 58 connecting members engage helical feature 62 which are forced in one direction, open or closed, depending on the direction of rotation of tube 54.

In one arrangement, window coverings 52 are wireless and battery powered, and include an internal power source 66, such as a plurality of batteries stacked within the tube 54 or a battery pack positioned within the tube 54. In another arrangement, window coverings 52 are connected to an external power source.

Control Module: Motorized window coverings 52 have a control module 68 connected thereto or positioned therein. Control module 68 receives electromagnetic signals from and communicates with voice activation module 12 which controls the operation of motorized window covering 52. Control module 68 is formed of any suitable arrangement and includes any and all necessary components to function properly. In one arrangement, control module 68 includes an antenna 70, which is similar or identical to antenna 46; a transceiver 72, which is similar if not identical to transceiver 40 (and in one-way

communication may only be a receiver); a microprocessor 74 and memory 76, which are similar if not identical to microprocessor 42 and memory 44. Control module 68 is also electronically connected to power source 66 which supplies power to the needed components of motorized window covering 52 (which in one arrangement is a plurality of batteries 66). At least one motor 78 is also connected to and controlled by control module 68 which converts electrical energy to mechanical energy thereby actuating the opening or closing or other function of the motorized window covering 52.

Assembly: One or a plurality of motorized window coverings 52 are assembled and installed having a control module 68 having an antenna 70, transceiver 72, microprocessor 74, memory 76 and motor 78 which are connected to power source 68. A voice activation module 12 is inserted into a standard wall plug-in within effective over-the-air communication distance to motorized window coverings 52. Voice activation module 12 is wirelessly connected to the motorized window coverings 52 via over-the-air two-way communication through antennas 46/70 and transceivers 40/72.

Commands And Control: Voice activation module 12 is preprogrammed to recognize a trigger phrase 80 and plurality of voice commands 82. In one arrangement, microprocessor 42 of voice activation module 12 is or includes the NLP-5x chip manufactured by Sensory Inc. of 4701 Patrick Henry Drive, Bldg. 7 Santa Clara, CA 95054. Alternatively, any other similar hardware and/or software that facilitates voice or sound recognition is used. The NLP- 5x includes voice recognition algorithms 84 created by Sensory Inc. to assist with recognition of the trigger phrase 80 and voice commands 82. Algorithms 84 make recognition of trigger phrase 80 more robust to background noise than voice commands 82 as recognition of the trigger phrase 80 brings voice activation module 12 out of a sleep state and/or into an awake state wherein voice activation module 12 is prepared to send command signals to motorized window coverings 52 based on a voice command 82.

Voice activation module 12 is preprogrammed to recognize trigger phrase 80. Trigger phrase 80 can be any word, sound, phrase, series of words, series of sounds, sentence of the like. As one example, the trigger phrase 80 is "Hello QMotion". Voice activation module 12 is also preprogrammed to recognize a plurality of voice commands 82. As examples these voice commands 82 include "Open" 86, "Close" 88, "Position One" 90, "Position Two" 92, "Position Three" 94. Any other number of position positions can be learned. Any number of commands can be preprogrammed without limitation. In addition, while "Open" 86, "Close" 88, "Position One" 90, "Position Two" 92, "Position Three" 94 are used as examples for voice commands 82, these are only examples. Any other term or phrase can be used as voice commands 82 as can any language. As one example, "Middle" can be used in lieu of

"Position Two" 92. In the arrangement described, as one example, the "Open" 86 command actuates motorized window covering 52 to a preprogrammed open position; the "Close" 88 command actuates motorized window covering 52 to a preprogrammed closed position; the "Position One" 90 actuates the motorized window covering 52 to a position of approximately 25% closed; "Position Two" 92 actuates the motorized window covering 52 to a position of approximately 50% closed or half-closed; and "Position Three" 94 actuates the motorized window covering 52 to a position of approximately 75% closed. While these may be the predetermined initial settings from the factory, any other position can be customizable set by the user to any other position between fully open and fully closed.

Groups: When using voice activation module 12 within effective over-the-air communication distance to a plurality of motorized window coverings 52, various motorized window coverings 52 can be organized into groups 96 using a group modifier 98. That is, once the system 10 is set-up, groups 96 are learned to the voice activation module 12 using a group modifier 98 to a voice command 82. As one example, group modifier 98 may include "Left Group" to indicate a group of motorized window coverings 52 positioned to the left side of a room, "Right Group" to indicate a group of motorized window coverings 52 positioned to the right side of a room, "Middle Group" to indicate a group of motorized window coverings 52 positioned at the middle of a room, as examples. When a group modifier 98 is recognized by voice activation module 12, transceiver 40 issues a limited control signal 99.

In Operation: One or a plurality of motorized window coverings 52 are assembled and connected, each motorized window covering 52 having a control module 68, an antenna 70, a transceiver 72, a microprocessor 74 and memory 76. At step 100, a voice activation module 12, having a microphone 36, a transceiver 40, a microprocessor 42, memory 44, an antenna 46 and an indicator 48 is connected to a conventional wall plug-in or is powered with batteries 15, positioned within effective over-the-air communication distance to motorized window coverings 52 and powered on.

At step 102 the plurality of motorized window coverings 52 are learned to the voice activation module 12. At this step, the open position 86, closed position 88, position one 90, position two 92, position three 94 and any other position are learned and associated with their respective voice command 82. In addition, the plurality of motorized window coverings 52 are organized into groups 96 and associated with their respective group modifier 98, such as "Left Group", "Right Group, and "Middle Group". Position information associated with each voice command 82 stored in memory 44/76 of microprocessor 42/74 and associated with each voice command. Unique identification information for each motorized window covering 52 is also stored in memory 44/76 of microprocessor 42/74 and associated with each voice command 82. Any other commands are learned at step 102.

Once the voice activation module 12 is learned to the motorized window coverings 52, and all necessary information is stored in memory 44/76 of microprocessor 42/74, voice activation module 12 begins main loop at step 104. Once in the main loop, at step 104, standard operation begins. At step 106, voice activation module 12 constantly listens to sounds in the environment through microphone 36. As sounds are received by microphone 36, these sounds are converted to an electronic signal and transmitted to microprocessor 42. Microprocessor 42 filters these signals and pursuant to the instructions saved into memory 44 as well as the voice recognition algorithms 84, microprocessor 42 constantly attempts to determine whether trigger phrase 80 has been received by microphone 36. This step requires filtering out background noise from trigger phrase 80 and recognizing trigger phrase 80. Algorithms 84 help with recognition of trigger phrase 80 from background noise and makes trigger phrase recognition robust to background noise contamination.

At this step, in one arrangement, when no sounds above a minimum threshold level are received by microphone 36, voice activation module 12 goes into a sleep state, or a power conserve state. When sounds are again received by microphone 36 above the minimum threshold level, voice activation module 12 enters into an awake state and again begins to determine whether an audible trigger phrase 80 was received. Depending on the state of the voice activation module 12, the indicator 48 may change state, as an example, when indicator 48 is a light, the light is off in a sleep state, the light is on in an awake state; alternatively, the light is green when analyzing sounds, the light is red when sounds cannot be understood, etc.

At step 108, trigger phrase 80 is recognized by microprocessor 42. At step 1 10, once the trigger phrase 80 is recognized, voice activation module 12 listens for any voice command 82 for a predetermined amount of time. In one arrangement, voice activation module 12 listens for three seconds, however any other amount of time is hereby contemplated such as one second, two seconds, four seconds, five seconds, six seconds, seven seconds, eight seconds, nine seconds, ten seconds, or more or the like. As sounds are received by microphone 36, these sounds are converted to an electronic signal and transmitted to microprocessor 42. Microprocessor 42 filters these signals and pursuant to the instructions saved into memory 44 as well as the voice recognition algorithms 84, within the

predetermined time period microprocessor 42 uses an algorithm 84, to recognize a voice command 82 was received. In one arrangement, algorithm 84 used to recognize a voice command 82 is less robust than the algorithm 84 used to recognize a trigger phrase 80.

In one arrangement, during the predetermined period of time at step 1 10, indicator 48 is activated. That is, in the example wherein indicator 48 is a light, the light is illuminated at the moment trigger phrase 80 is recognized and remains illuminated during the predetermined amount of time for recognizing a voice command 82. This provides a user with an instantaneous and real-time visual double check and confirmation that voice activation module 12 recognized the trigger phrase 80 and is awaiting a voice command 82. Indicator 48 also provides the user with an instantaneous and real-time visual indication that the voice activation module 12 is no longer listening for a voice command 82 as too much time has elapsed between trigger phrase 80 and voice command 82. With this visual information, the user immediately knows that another trigger phrase 80 must be spoken in order to transmit a command signal.

Similarly, indicator 48 can be used to issue a visual signal upon reception of a trigger phrase 82, at entry into the waiting period for a voice command 82, at the expiration of the waiting period for a voice command 82, at the reception of a voice command 82, or at any other time. In one arrangement, indicator 48 is a light capable of producing multiple colors such that when a command is received and recognized the light is one color (such as green) and when a command is received and not recognized the light is another color (such as red). Similarly, microphone 36 (acting as a speaker) can be used to issue an audible signal upon reception of a trigger phrase 82, at entry into the waiting period for a voice command 82, at the expiration of the waiting period for a voice command 82, at the reception of a voice command 82, or at any other time. Or, alternatively, microphone 36 is used to transmit more than one audible signal, such as a happy, uplifting, or positive tone after each voice command 82 is received, and/or a sad, negative, or downbeat tone whenever the time period expires or a voice command 82 is not received within the specified period of time after recognizing a trigger phrase 80.

At step 1 12, a voice command 82 is recognized by microprocessor 42. Once voice command 82 is recognized, microprocessor 42 compares the voice command 82 with information and instructions saved within memory 44. At Step 1 14, voice activation module 12 transmits an electromagnetic signal or control signal 99. More specifically, when microprocessor 42 recognizes a voice command 82, microprocessor 42 instructs transceiver 40 to transmit a corresponding control signal 99 to motorized window coverings 52 through antenna 46.

This control signal 99 travels over-the-air and is received by antenna 70 of motorized window covering 52. Antenna 70 transmits the electromagnetic signal to transceiver 72. Transceiver 72 interprets the electromagnetic signal and converts it to digital signal of 1 s and 0s. This digital signal is then transmitted by transceiver 72 to microprocessor 74.

Microprocessor 74 reads and interprets the digital signal based on the code and instructions saved within memory 76. If the signal is intended for that specific motorized window covering 52, microprocessor 74 instructs motor 78 to actuate to the specified position which corresponds to the control signal 99.

In a two-way communication system, after activation or reception of a control signal 99, microprocessor 74 of motorized window covering 52 instructs transceiver 72 to transmit an acknowledgement of reception, or acknowledgement of activation, or acknowledgement of position, electromagnetic signal to voice activation module 12. Similar to that described previously herein with respect to motorized window covering 52, this electromagnetic signal is received by voice activation module 12 at antenna 46, transmitted to transceiver 40, converted into a digital signal of I s and 0s and transmitted to microprocessor 42 wherein it is interpreted based on instructions stored in memory 44. Based on this information, voice activation module 12 will know the status of the motorized window coverings 52, know whether the command signal 99 was received, know the position of the motorized window coverings 52 or any other information requested. This information provides voice activation module 12 the ability to know whether the signal must be resent.

Remote: In one manner, a remote transmitter 1 16, having an up button 1 16A, a down button 1 16B, a first position button 1 16C, a second position button 1 16D, a third position button 1 16E, a jog up button 1 16F and a jog down button 1 16G is wirelessly connected to the plurality of window coverings 52. Open button 1 16A, when activated, opens motorized window coverings. Close button 1 16B, when activated, closes motorized window coverings.

First 1 16C, second 1 16D and third position 1 16E buttons, when activated, move motorized window coverings 52 to a first predetermined position, a second predetermined position and a third predetermined position respectively. In one arrangement, these first, second and third predetermined positions are set at approximately 25% open, 50% open (or half open) and 75% open, respectively. While these may be the initial settings, first, second and third predetermined positions are customizable and can be set at any position by the user. The jog up button and a jog down button when activated, move motorized window coverings a predetermined incremental amount between the open position and closed position. Any predetermined incremental amount is hereby contemplated such as is 1 %, 2.5%, 5%, 7.5%, 10%, 12.5%, 15%, 17.5%, 20%, 22.5% or 25%, or the like. Or, alternatively, a specified distance is predetermined such as 1 inch, 2 inches, 3 inches, 4 inches, 5 inches 6 inches 7 inches, 8 inches, 9 inches, 10 inches, 1 1 inches, 12 inches, 13 inches, 14 inches, 15 inches, 16 inches, 17 inches, 18 inches, 19 inches, 20 inches, 21 inches, 22 inches, 23 inches, 24 inches, or the like.

A similar process occurs when the up button 50A or down button 50B is pressed on the voice activation module 12. At step 1 18 a button 50A or 50B is pressed, at which point a control signal 99 is sent to motorized window coverings 52. In this way, voice activation control works like a voice activated remote control. At step 120 button 50A or 50B is continuously held, instead of being pushed and released. Upon recognition that button 50A or 50B is continuously held, at step 122, motorized window covering 52 enters into a learn mode.

Examples Of Voice Commands: As a first example, a user desiring to open all motorized window coverings within over-the-air effective communication distance to a voice activation module 12 may say "Hello QMotion", the trigger phrase 80, followed by "Open" within the predetermined three seconds. In response, voice activation module 12 transmits an open 86 command signal 99 to all motorized window coverings 52 wirelessly connected to voice activation module 12.

As a second example, a plurality of motorized window coverings have learned position one, two and three to correspond to a 25%, 50% and 75% closed position, respectively. A user desiring to open all motorized window coverings to 50% may say "Hello QMotion", the trigger phrase 80, followed by "Position Two" 92 within the predetermined three seconds. In response, voice activation module 12 transmits a command signal 99 to all motorized window coverings 52 wirelessly connected to voice activation module 12 to actuate them to a middle position. As a third example, a plurality of motorized window coverings in a single room have been organized into three groups 96, a left group, a middle group and a right group, and learned to these group modifiers 98 respectively. A user desiring to close only the left group of motorized window coverings may say "Hello QMotion", the trigger phrase 80, followed by "Left Group", the group modifier 98, followed by "Close" within the predetermined three seconds. In response, voice activation module 12 transmits a control signal 99 to all motorized window coverings 52 wirelessly connected to voice activation module 12.

However, using the unique ID's associated with each motorized window covering 52, this control signal 99 is directed only to the specified window coverings 52 associated with the left group. These motorized window coverings actuate to a closed position, while the remaining window coverings remain unchanged.

In one arrangement, a voice activation module 12 may recognize and be learned for the following voice commands 82:

To make the motorized window covering 52 to move to a position:

"Open Shade" or "Shade Open"

"Close Shade" or "Shade Close'

"Position One" or "25 Percent"

"Position Two" or "50 Percent" or "Middle" or "Half or "Half Open" or "Half

Closed"

"Position Three" or "75 Percent"

These voice commands82 are followed by activation of the motorized window covering 52.

To add or remove transmitters 1 16:

"Device Learn Mode"

"Learn Device"

"Remove Device"

These voice commands 82 are followed by a single button press on the transmitter 1 16, a double button press on the transmitter 1 16, a single button press and hold for x-seconds on the transmitter 1 16, a double button press and hold for x-seconds on the transmitter 1 16, or any other method of associating the transmitter 1 16 with the particular motorized window coverings 52. To change shade position presets to a customized position:

"Position Learn Mode"

"Learn Position"

These commands 82 are followed by a position learning sequence on the specific motorized window coverings 52. In one arrangement, this sequence includes tugging the shade material 56, to select the appropriate shade, then moving the shade material 56 to the appropriate position.

Turn audio feedback On/Off:

"Audio Off

"Audio On"

These commands 82 turn on or off the audio confinnation signal when the trigger phrase 80 is recognized, the wait period terminates, a voice command 82 is recognized or any other process or event occurs.

Turn relay (repeater) mode On/Off:

"Relay Mode Off

"Relay Mode On"

These commands 82 turn on or off the repeater function of voice activated module 12. In "Relay Mode On" mode, whenever voice activated module 12 receives an electromagnetic signal, such as a control signal 99, the voice activation module 12 repeats this signal. This provides the benefit of repeating the electromagnetic signal at a higher power so as to ensure that the control signal 99 reaches and is heard by the intended motorized window coverings 52.

To control all motorized window coverings 52 associated with the system 10 at the same time:

"All"

As a modifier, "All" is used before or after a voice command 82 to instruct the voice activation module 12 to instruct all motorized window coverings 52 associated with the system 10 to perform the following voice command 82. As an example "Hello QMotion ... All ... Open" or "Hello QMotion ... Close ... All" this will cause voice activation module 12 to send a control signal 99 to all motorized

window coverings 52 to open or close, respectively, using a single instruction. This voice command will open all motorized window coverings 52 in a home, building, office or the like. The reach of voice activation module 12 will be improved using multiple voice activation modules 12 when they are in "Relay Mode On" mode. In this way, when a user issues a voice command 82 in one room of a building having a voice activation module 12, that voice activation module 12 will recognize the voice command 99 and transmit it using an electromagnetic signal a further distance than the user's voice command will travel. Each additional voice activation module 12 that receives this electromagnetic signal will repeat it, and so on.

"Left", "Right", "Middle", "Top", "Bottom", "First Group", "Second Group",

"Third Group", "Fourth Group", etc., "Kitchen", "Bedroom", "Office",

"Family Room", "Dining Room", etc.

These modifiers are used to direct commands to specific groups of motorized window coverings. These groups are learned by the voice activation unit 12 by associating a unique ID associated with each motorized window covering with each group and transmitting control signals 99 directed specifically to those motorized window coverings 52. These modifiers can be used before or after a voice command 99 to instruct the voice activation module 12 to instruct only those specified motorized window coverings 52 to perform the following voice command 82. As an example "Hello QMotion ... Kitchen ... Open" or "Hello QMotion ... Close ... Middle" or "Hello QMotion ... Third Group ... Position One" this will cause voice activation module 12 to send the specified control signal 99 to only the motorized window coverings 52 associated with the identified group.

To restart listening for a command:

"Hello QMotion"

Countless other voice commands 82 and modifiers 98 can be programmed and/or learned and used in any manner described herein. Entering Learn Mode: The learn mode is entered into using any one of a number of ways.

First Method Example - Entering Learn Mode With Voice Commands: With the motorized window covering 52 in an open position and the voice activation module 12 plugged-in within effective over-the-air communication distance the user says the trigger phrase 80 "Hello QMotion". If the trigger phrase 80 is recognized (the indicator light 48 illuminates and/or an audio confirmation is issued) the user says the voice command 82 "Device Learn Mode" within the specified wait period. The voice activation module 12 will acknowledge if the command was received and accepted or rejected through indicator 48, with green or red LEDs and positive or negative audible beeps. If recognized, the motorized window covering 52 will actuate to approximately a 75% closed position of the total distance between an open position and a closed position, at which point the user tugs a specified window covering 52 to enter learn mode.

Second Method Example - Entering Learn Mode With a Two Button Press: With the motorized window covering 52 in an open position and voice activation module 12 and/or transmitter 1 16 within effective over-the-air communication distance the user performs a two button press on the transmitter 1 16 or the voice activation module 12. This requires pressing the up button 5 OA or 1 16A and down button 50B or 1 16B and holding them for a

predetermined amount of time, such as five, ten or fifteen seconds or the like. If recognized, the motorized window covering 52 will actuate to approximately a 75% closed position of the total distance between an open position and a closed position, at which point the user tugs the specified window covering 52 to enter learn mode.

Third Method Example - Entering Learn Mode With Buttons On Known Transmitter: With the motorized window covering 52 in an open position and voice activation module 12 and transmitter 1 16 within effective over-the-air communication distance to one another, hold the up button 50A on an already learned transmitter for a predetermined amount of time, such as fifteen seconds. The motorized window covering 52 will move down slightly then back up after approximately five seconds, however the user must continue to hold the up button 50A for the remaining five seconds of the ten second period. The motorized window covering 52 will then move to approximately a 75% closed position of the total distance between an open position and a closed position, at which point the user tugs the specified window covering 52 to enter learn mode. Fourth Method Example - Entering Learn Mode By Powering Up: When the motorized window covering 52 is powered up form a total shut-down (all power off) when re- powered, the motorized window covering 52 will move to approximately a 75% closed position of the total distance between an open position and a closed position, at which point the user tugs the specified window covering 52 to enter learn mode.

Learning The Voice Module 12 To The Motorized Window Covering 52: Once the motorized window covering 52 is in learn mode, the voice activation module 12 is learned to the motorized window covering 52 in the following examples.

First Method Example - Using Voice Commands: The user states the trigger phrase 80 "Hello QMotion". If the trigger phrase 80 is accepted, the user issues voice command 82 "Learn Device". The motorized window covering will move to the open position and will acknowledge the voice activation module 12 as a learned transmitter. The voice activation module 12 can now be used to operate and control the motorized window covering 52.

Second Method Example - Using Buttons On The Voice Activation Module: The user holds the open button 50A on the voice activation module 12 for a predetermined amount of time, such as approximately five seconds. The motorized window covering will move to the open position and will acknowledge the voice activation module 12 as a learned transmitter. The voice activation module 12 can now be used to operate and control the motorized window covering 52.

These methods can be used to learn a voice activation module to one or a plurality of motorized window coverings 52.

Repeater/Relay Mode: In more-complicated or expansive systems, such as large homes, office buildings or commercial properties, a single voice activation module 12 or a single transmitter 1 16 may not be able to reach all of the motorized window coverings therein due to the inherent and statutory limits associated with RF communication. In these applications, to help ensure that command signals 99 reach each and every motorized window covering 52 voice activation module 12 has a relay or repeater mode. In the relay or repeater mode, voice activation module 12 simultaneously listens for voice commands 82, spoken by a user, as well as control signals 99, transmitted by any other associated device, such as another voice activation module 12, a transmitter 1 16, a wireless gateway which is controlled by a computer, laptop, tablet, smart phone or similar user controlled electronic device, or the like. In this arrangement, transceiver 40 of voice activation module 12 receives an electromagnetic control signal 99 through antenna 46 and passes it to microprocessor 42. Microprocessor 42 recognizes that the electromagnetic signal is a control signal 99 from an associated device. The Microprocessor 42 instructs transceiver 40 to transmit the control signal 99 after a specified delay. In this way, voice activation module 12 acts as a relay or a repeater. This helps to actuate distant motorized window coverings 52 by passing the control signal 99 from voice activation module 12 to voice activation module 12 and so on. In this arrangement, a distant voice activation module 12 may receive a control signal 99 that is of low strength or quality due to dispersion and repeat that signal with high strength and high quality. This strong and clear signal improves the chances that each intended motorized window covering 52 will receive the control signal 99 and respond appropriately. In one arrangement, where voice activation module 12 is connected to an endless power supply and motorized window coverings 52 are battery powered, voice activation module 12 is particularly well suited to continuously listen for control signals 99 repeat them high strength and quality because they are not limited by power. This same arrangement applies in a two- way communication system wherein the motorized window coverings 52 transmit responsive signals to voice activation module 12. The voice activation module 12 can also serve as a relay for learned remotes (transmitter 1 16) and not just other voice activation modules 12.

As one example of this arrangement, with reference to Fig. 8, a user in one room of a multi-room system issues a voice command 82 such as "Hello QMotion ... Open ... Α1Γ which is intended to open all motorized window coverings 52 associated with the system 10. The user's voice reaches the nearest voice activation module 12A, however it does not reach the other voice activation modules 12B, 12C ... etc. Voice activation module 12A transmits a control signal 99 that reaches the nearest groups A l, A2, A3, A4 of motorized window coverings 52 with sufficient strength and clarity that this signal is easily received and interpreted by these motorized window coverings 52 such that they reliably actuate to the correct position. As control signal 99 emanated by voice activation module 12A travels it loses strength and/or clarity due to dispersion and/or interference. Due to distance, control signal 99, may or may not reach the motorized window coverings 52 of the groups B l, B2, B3, B4, with sufficient strength and clarity to be easily received and interpreted by these motorized window coverings 52. If these motorized window coverings 52 receive the control signal 99 from voice activation module 12A, they will actuate. If on the other hand, if these motorized window coverings 52 do not receive the control signal 99 from voice activation module 12A, they will not actuate. However, because voice activation module 12B is plugged into a constant power source, voice activation module 12B constantly listens for control signals 99, and when in relay mode, relays these signals at higher power, strength and clarity. Therefore, when voice activation module 12B receives the control signal 99 from voice activation module 12A, voice activation module 12B repeats it, after a small delay. Due to the fact that motorized window coverings 52 of the groups Bl , B2, B3, B4 are physically closer to voice activation module 12B, they receive a strong and clear signal and actuate to the desired position. This process repeats itself through additional groups CI, C2, C3, C4, etc., and additional voice activation modules 12C, etc. Two-way communication between motorized window coverings 52 and voice activation modules 12, which occurs similarly to that described herein, only in the opposite direction, helps to assure that the specified motorized window coverings 52 actuate when directed to do so. That is two-way communication ensures that the window coverings 52 only activate once per signal.

Modifications: While the herein described examples include the voice activation module 12 being a separate unit from the motorized window coverings 52, in an alternative arrangement, the voice activation module 12 is included within and a part of the motorized window covering 52. This arrangement eliminates the need for additional componentry and simplifies the design.

In addition to using voice activation module 12 to control motorized window coverings 52, either through voice commands 82 or by pressing buttons 50, motorized window coverings 52 can be controlled using transmitter 1 16 as well as tugging on shade material 56 of either a roller shade or drapery. Tugging on shade material 56 is sensed by a sensor of the control module 68. Motorized window covering 52 responds to recognition of a tug by actuating the motorized window covering to a predetermined position. As one example, when motorized window covering recognizes a single tug, motorized window covering 52 actuates to an open position. As a second example, when motorized window covering 52 recognizes two tugs, motorized window coverings 52 actuates to a closed position. As a third example, when motorized window covering 52 recognizes three tugs, motorized window covering 52 actuates to a third position. This arrangement presents a never before found system that allows for voice activation as well as transmitter activation as well as activation by tugging shade material 56. From the above discussion it will be appreciated that a system and method for wireless voice activation of motorized window coverings is presented that improves upon the state of the art.

That is, the system and method for wireless voice activation of motorized window coverings presented is easy to use, intuitive, and simple and provides a plurality of novel ways to actuate the motorized window coverings. In addition, the system and method for wireless voice activation of motorized window coverings presented is inexpensive, allows for the activation of a plurality of window coverings simultaneously, allows for grouping of a plurality of motorized window coverings and provides visual as well as audible feedback to the user during the voice recognition process. As such, all of the stated objectives have been accomplished.

It will be appreciated by those skilled in the art that other various modifications could be made to the device without parting from the spirit and scope of this invention. All such modifications and changes fall within the scope of the claims and are intended to be covered thereby.
