  • screen bounce occurs, it causes the user to lose focus on the display content and slows down and reduces precision of sequential user touch events.
  • Most current known solutions rely on passive damping from the material which is not effective at quickly returning the display to equilibrium.
  • chassis reduce in thickness, it can be increasingly difficult to provide enough structure for passive damping to react and dampen touch screen bounce from user touch input. What is needed is a system and method that reduces screen bounce and hinge slip by sensing incoming user touch dynamics and proactively engaging a reaction force from an active control mechanism to reduce the displacement of the touchscreen after a touch event.
  • An electronic device as outlined herein can resolve these issues (and others). Particular embodiments described herein provide for an electronic device that is configured to include bounce reduction engine 112. Bounce reduction engine 112 can be configured to utilizes input from a sensor array such as 3D cameras, proximity detection, and accelerometers (e.g., screen proximity sensor 108, screen bound detection engine 110, etc.) in conjunction with an active control drive to reduce bounce settling time and minimize peak displacement after a touch event.

EXAM PLE EM BODI M ENTS
[0021] The following detailed description sets forth example embodiments of apparatuses, methods, and systems relating to detachable display configurations for an electronic device. Features such as structure(s), function(s), and/or characteristic(s), for example, are described with reference to one embodiment as a matter of convenience; various embodiments may be implemented with any suitable one or more of the described features.
[0022] FIGURE 1 is a simplified schematic diagram illustrating an embodiment of an electronic device 100, in accordance with one embodiment of the present disclosure. Electronic device 100 can include a display 102, a display support 104, a bounce reduction mechanism 106, a screen proximity sensor 108, a screen bounce detection engine 110, and a bounce reduction engine 112. In one or more embodiments, electronic device 100 is a tablet computer. In still other embodiments, electronic device 10 may be any suitable electronic device having a display such as a mobile device, a tablet device (e.g., i-Pad™), Phablet™, a personal digital assistant (PDA), a smartphone, an audio system, a movie player of any type, etc. In an example, bounce reduction engine 106 can function as a hinge to rotatably couple display 102 and display support 104.
[0023] In one or more embodiments, display 102 can be a touchscreen display that can detect the presence and location of a touch within a display area. For example, display 102 can detect when a user's hand (or some other input devices such as a stylus) reacts with display 102. Electronic device 100 can include a battery and various electronics (e.g., processor, memory, etc.) to allow electronic device 100 to operate as a standalone tablet. Electronic device 100 may also include a wireless module, (e.g., Wi-Fi module, Bluetooth module, etc.) a camera, a microphone, and speakers.
[0024] For purposes of illustrating certain example features of communication system 100, the following foundational information may be viewed as a basis from which the present disclosure may be properly explained.
[0025] A current technological trend is a touchscreen. Unfortunately, screen bounce is a common user pain point on touch devices such as clamshells, detachable 2-in-l's, and docked tablets. This pain point has also become an ongoing issue with recent tablet design implementations for wireless charging using pedestal style kickstands. When screen bounce occurs, it causes the user to lose focus on the display content and slows down and reduces precision of sequential user touch events. Most current known solutions rely on passive damping from the material which is not effective at quickly returning the display to equilibrium. Also, as chassis reduce in thickness, it can be increasingly difficult to provide enough structure for passive damping to react and dampen touch screen bounce from user touch input. What is needed is a system and method that reduces screen bounce and hinge slip by sensing incoming user touch dynamics and proactively engaging a reaction force from an active control mechanism to reduce the displacement of the touchscreen after a touch event.
[0026] An electronic device as outlined herein can resolve these issues (and others). Particular embodiments described herein provide for an electronic device that is configured to include bounce reduction engine 112. Bounce reduction engine 112 can be configured to utilizes input from a sensor array such as 3D cameras, proximity detection, and accelerometers (e.g., screen proximity sensor 108, screen bound detection engine 110, etc.) in conjunction with an active control drive to reduce bounce settling time and minimize peak displacement after a touch event.
[0027] Bounce reduction engine 112 can be configured to allow for adjustment and be active, strongly active, turned off, etc. depending on the power state of electronic device 100 and/or user preference. Bounce reduction engine 112 can also use sensor data already existing in current electronic devices to calculate phase and amplitude of anti-bounce force input. In addition, the system and method can scale with system torque requirements from small form factors to large all-in ones.
[0028] In a specific example, when a user (e.g., with user's hand 142, stylus, etc.) is interacting with a touch screen (e.g., display 102), there is an opportunity to capture input device motion before and up to a touch event for the purpose of proactively mitigating screen bounce and displacement issues and as part of an active control system. For example, screen proximity sensor 108 can be configured to input device motion towards display 102. As the input device approaches display 102 to interact with display 102, proximity sensor 108 can detect the incoming speed and predict impact time and magnitude based on acquired data and control logic which can be used in conjunction with passive control from acquired accelerometer data to mitigate screen bounce. In an example, predicted impact dynamics can be used to engage a proactive response of an active control system (e.g., bounce reduction engine 112) to reduce screen displacement and quickly dampen oscillations.
[0029] Turning to FIGURE 2, FIGURE 2 is a simplified block diagram of a portion of electronic device 100 in accordance with one embodiment of the present disclosure. As illustrated in FIGURE 2, electronic device 100 can include four display regions 1001-llOd. Each region of display 102 can include a screen bounce detection engine designed for the region. For example, display region 114a may be located in an upper left area of display device and can include screen bounce detection engine 110a, display region 114b may be located in an upper right area of display device and can include screen bounce detection engine 110b, display region 114c may be located in an lower left area of display device and can include screen bounce detection engine 110c, and display region 114d may be located in an lower right area of display device and can include screen bounce detection engine llOd. A screen bounce detection engine may be located in each region because the screen bounce in display region 114a can be very different from the screen bounce in display region 114d. By including a screen bounce detection engine in each region, an accurate assessment of screen bounce in each region can be determined. [0030] Turning to FIGURE 3, FIGURE 3 is a simplified block diagram of a docking station 116 in accordance with one embodiment of the present disclosure. Docking station 116 can include bounce reduction mechanism 106, one or more bounce detection engines llOe and llOf, bounce reduction engine 112, a device support 118, interconnect 120, and base 144. Interconnect 120 can be configured to couple an electronic device (e.g., electronic device 100) to docking station 116 can help facilitate communications between the electronic device and docking station 116. Each bounce detection engine llOe and llOf can be configured to detect bounce or oscillations of device support 118. For example, when a user interacts with a touchscreen associated with an electronic device coupled to docking station 116, the interaction may cause the display and device support 118 to bounce. Also, when an electronic device is first coupled to docking station 116, device support 118 and the display on the electronic device may experience bounce or oscillations.
[0031] In an example, docking station 116 can be configured to allow for wireless charging. With the planned growth of wireless charge integration, a pedestal kickstand can provide flexibility to adjust screen angle while wirelessly charging. However, this is more susceptible to screen bounce and\or hinge slip due to the long span between the hinge axis and top of the touch screen. Bounce reduction engine 112 can be configured to ensure a controlled system bounce response even for thin tablets with pedestal kickstands.
[0032] Turning to FIGURE 4, FIGURE 4 is a simplified block diagram of a portion of docking station 116 in accordance with one embodiment of the present disclosure. In an example, bounce reduction mechanism 106 can include a linear actuator 138 and a piston 140. In an example, bounce reduction mechanism 106 can be part of a pedestal kickstand style. Bounce reduction mechanism 106 can provide active resistance by using variable friction to absorb a desired amount of friction and reduce bouncing or oscillations of a touchscreen. Bounce reduction mechanism 106 can be configured to not provide too much resistance and create a bounce back or amply the bouncing of the touch screen.
[0033] Turning to FIGURE 5, FIGURE 5 is a simplified block diagram of a clamshell electronic device 122 in accordance with one embodiment of the present disclosure. Clamshell electronic device 122 can include a first housing 124 and a second housing 126. First housing 124 can include a bounce detection engine 110 and touchscreen display 130. Second housing 126 can include bounce reduction engine 112. In an example, bounce reduction engine 112 can be located in first housing 124. First housing 124 can be coupled to second housing 126 using hinge 128. Hinge 128 can be configured with active elements to reduce bounce or oscillations of first housing 124.
[0034] In an example, hinge 128 can include a continuous hinge design. For example, hinge 128 can include a continuous membrane of artificial muscle that attaches first housing 124 to second housing 126 and provides a sleek monolithic look.
[0035] The continuous membrane can include EAP cells and may be controlled electrostatically by bounce reduction engine 112. In an example, a simple voltage controller can control the voltage to the membrane causing it to expand and contract to provide the needed motion. When the voltage is increased the membrane contracts in one direction and expands in the other. By applying membrane segments independent of another it is possible to have expansion and contracting membranes coupled together which cause the bending of polymer film.
[0036] In an embodiment, first housing 124 can be rotated away from second housing 126, (e.g., opened and closed) using voice command or touch or activation of a button. The open close position can be set to a predetermined position or adjusted infinitely automatically. Once open, the position or angle of first housing 124 can be adjusted by hand. The EAP has the ability to sense load by sensing change in capacitance. As a load is applied, the capacitance of the EAP cell changes. Based on load and duration, it can be relatively easy to detect the load is intentional and to allow the position of the display to adjust and then maintain position.
[0037] In another embodiment, inputs to touchscreen 130 can cause a "bounce" in first housing 124 that will change the capacitance. As this change in capacitance is detected it is translated into movement of touchscreen 130. Bounce reduction engine 112 can be configured to respond with input to dampen the motion and quickly reduce the display bounce and return the display to a nominal position.
[0038] Turning to FIGURE 6, FIGURE 6 is a simplified block diagram of a portion of clamshell electronic device 122 in accordance with one embodiment of the present disclosure. In an example, hinge 128 can include a rotation drive configured as an active control drive to reduce bounce or oscillations of first housing 124. In an example, a piezo motor 136 can vibrate using a wave signal to generate torque on a hinge shaft 134 through a friction surface. The increase in torque affects the rotation of hinge shaft 134 on rotation member 132 and can dampen oscillations or bouncing of first housing 124.
[0039] Turning to FIGURE 7, FIGURE 7 is a simplified block diagram of a portion of a hinge in accordance with one embodiment of the present disclosure. In an example, the hinge can include an oscillating piezoceramic actuator 142, a coupling element 144, and a runner 146. In an example, a bounce reduction engine can activate oscillating piezoceramic actuator 142 which would activate oscillating arm 148 and allowing 146 to walk or move in a desired direction and dampen the bounce or oscillations of a touchscreen. While various methods and means are illustrated for dampening the bounce or oscillations of a touchscreen, other methods and means may be used such as compact solenoids or artificial muscles and all are within the scope of this application.
[0040] Turning to FIGURE 8, FIGURE 8 is an example flowchart illustrating possible operations of a flow 800 that may be associated with the reduction of touchscreen bounce, in accordance with an embodiment. In an embodiment, one or more operations of flow 800 may be performed by bounce detection engine 110 and bounce reduction engine 112. At 802, input device motion towards a display is detect. For example, screen proximity sensor 108 may detect the motion of user's hand 142 as it approaches display 102. At 804, an incoming velocity towards the display is calculated. At 806, the system determines if the incoming velocity is greater than a threshold. If the incoming velocity is greater than a threshold, a counter force is applied to the display, as in 808. For example, bounce reduction engine 112 may determine that the incoming velocity of user's hand 142 is greater than a threshold and therefore cause bounce reduction mechanism 106 to apply a counter force.
[0041] Turning to FIGURE 9, FIGURE 9 is an example flowchart illustrating possible operations of a flow 900 that may be associated with the reduction of touchscreen bounce, in accordance with an embodiment. In an embodiment, one or more operations of flow 900 may be performed by bounce detection engine 110 and bounce reduction engine 112. At 902, movement of an input device towards a display is detected. For example, screen proximity sensor 108 may detect the motion of user's hand 142 as it approaches display 102. At 904, an area of the display where the input device will contact the display is determined. For example, it may be determined if the input device will contact display region 114a, 114b, 114c, or 114d. At 906, a velocity of the input device is determined. At 908, the system determines if the velocity of the input device is greater than a threshold for the determined area of the display where the input device will contact the display. If the the velocity of the input device is greater than a threshold for the determined area of the display where the input device will contact the display, then a counter-force is applied to the display at the approximate time that the input device will contact the display. In an illustrative example, if user's hand 142 contacted display region 114d with a specific amount of force, display 102 may not bounce or oscillate past a threshold. However, if if user's hand 142 contacted display region 114a with the same specific amount of force, display 102 may oscillate past a threshold and a counter force may need to be applied.
[0042] Turning to FIGURE 10, FIGURE 10 is an example flowchart illustrating possible operations of a flow 1000 that may be associated with the reduction of touchscreen bounce, in accordance with an embodiment. In an embodiment, one or more operations of flow 1000 may be performed by bounce detection engine 110 and bounce reduction engine 112. At 1002, oscillation of an electronic device is detected. At 1004, the system determines if the oscillation is greater than a threshold. If the oscillations is greater than a threshold, then a counter force is applied to the electronic device to dampen the oscillation, as in 1006. For example, some type of active element such as bounce reduction mechanism 106, hinge shaft 134, or some other active element that can be activated to produce the counter force may be applied. Then, at 1004, the system again determines if the oscillation is greater than a threshold. If the oscillation is not greater than a threshold, the the process ends and a counter force is not applied.
[0043] Turning to FIGURE 11, FIGURE 11 is an example flowchart illustrating possible operations of a flow 1100 that may be associated with the reduction of touchscreen bounce, in accordance with an embodiment. In an embodiment, one or more operations of flow 1100 may be performed by bounce detection engine 110 and bounce reduction engine 112. At 1102, a default position of a display is determined. At 1104, the system determines if the display is in the default positon. If the system is not in the default position, then a force is applied to return the display to the default position, as in 1106. For example, some type of active element such as bounce reduction mechanism 106, hinge shaft 134, or some other active element that can be activated to produce the counter force may be applied. Then, the system returns to 1104 and determines if the display is in the default position. In an illustrative example, if a user is continuously pushing on the display, the system may determine that a counter force needs to be applied.
[0044] Turning to FIGURE 12, FIGURE 12 is an example flowchart illustrating possible operations of a flow 1200 that may be associated with the reduction of touchscreen bounce, in accordance with an embodiment. In an embodiment, one or more operations of flow 1200 may be performed by bounce detection engine 110 and bounce reduction engine 112. At 1202, a force that causes a displacement of a display is detected. At 1204, the system determines if the displacement of the display is greater than a threshold value. If the displacement is greater than a threshold value, then a counter force is applied to the display, as in 1206 and the system again determines if the displacement of the display is greater than a threshold value, as in 1204.
[0045] FIGURE 13 illustrates a computing system 1300 that is arranged in a point- to-point (PtP) configuration according to an embodiment. In particular, FIGURE 13 shows a system where processors, memory, and input/output devices are interconnected by a number of point-to-point interfaces. Generally, one or more of the network elements of communication system 100 may be configured in the same or similar manner as computing system 1300.
[0046] As illustrated in FIGURE 13, system 1300 may include several processors, of which only two, processors 1370 and 1380, are shown for clarity. While two processors 1370 and 1380 are shown, it is to be understood that an embodiment of system 1300 may also include only one such processor. Processors 1370 and 1380 may each include a set of cores (i.e., processor cores 1374A and 1374B and processor cores 1384A and 1384B) to execute multiple threads of a program. The cores may be configured to execute instruction code in a manner similar to that discussed above with reference to FIGURES 1-12. Each processor 1370, 1380 may include at least one shared cache 1371, 1381. Shared caches 1371, 1381 may store data (e.g., instructions) that are utilized by one or more components of processors 1370, 1380, such as processor cores 1374 and 1384.
[0047] Processors 1370 and 1380 may also each include integrated memory controller logic (MC) 1372 and 1382 to communicate with memory elements 1332 and 1334. Memory elements 1332 and/or 1334 may store various data used by processors 1370 and 1380. In alternative embodiments, memory controller logic 1372 and 1382 may be discrete logic separate from processors 1370 and 1380.
[0048] Processors 1370 and 1380 may be any type of processor and may exchange data via a point-to-point (PtP) interface 1350 using point-to-point interface circuits 1378 and 1388, respectively. Processors 1370 and 1380 may each exchange data with a chipset 1390 via individual point-to-point interfaces 1352 and 1354 using point-to-point interface circuits 1376, 1386, 1394, and 1398. Chipset 1390 may also exchange data with a high-performance graphics circuit 1338 via a high-performance graphics interface 1339, using an interface circuit 1392, which could be a PtP interface circuit. In alternative embodiments, any or all of the PtP links illustrated in FIGURE 13 could be implemented as a multi-drop bus rather than a PtP link.
[0049] Chipset 1390 may be in communication with a bus 1320 via an interface circuit 1396. Bus 1320 may have one or more devices that communicate over it, such as a bus bridge 1318 and I/O devices 1316. Via a bus 1310, bus bridge 1318 may be in communication with other devices such as a keyboard/mouse 1312 (or other input devices such as a touch screen, trackball, etc.), communication devices 1326 (such as modems, network interface devices, or other types of communication devices that may communicate through a computer network 1360), audio I/O devices 1314, and/or a data storage device 1328. Data storage device 1328 may store code 1330, which may be executed by processors 1370 and/or 1380. In alternative embodiments, any portions of the bus architectures could be implemented with one or more PtP links.
[0050] The computer system depicted in FIGURE 13 is a schematic illustration of an embodiment of a computing system that may be utilized to implement various embodiments discussed herein. It will be appreciated that various components of the system depicted in FIGURE 13 may be combined in a system-on-a-chip (SoC) architecture or in any other suitable configuration. For example, embodiments disclosed herein can be incorporated into systems including mobile devices such as smart cellular telephones, tablet computers, personal digital assistants, portable gaming devices, etc. It will be appreciated that these mobile devices may be provided with SoC architectures in at least some embodiments.
[0051] Turning to FIGURE 14, FIGURE 14 is a simplified block diagram associated with an example ARM ecosystem SOC 1400 of the present disclosure. At least one example implementation of the present disclosure can include the reduction of touchscreen bounce features discussed herein and an ARM component. For example, the example of FIGURE 14 can be associated with any ARM core (e.g., A-9, A-15, etc.). Further, the architecture can be part of any type of tablet, smartphone (inclusive of Android™ phones, iPhones™), iPad™, Google Nexus™, Microsoft Surface™, personal computer, server, video processing components, laptop computer (inclusive of any type of notebook), Ultrabook™ system, any type of touch-enabled input device, etc.
[0052] In this example of FIGURE 14, ARM ecosystem SOC 1400 may include multiple cores 1406-1407, an L2 cache control 1408, a bus interface unit 1409, an L2 cache 1410, a graphics processing unit (GPU) 1415, an interconnect 1402, a video codec 1420, and a liquid crystal display (LCD) l/F 1425, which may be associated with mobile industry processor interface (MIPI)/ high-definition multimedia interface (HDMI) links that couple to an LCD.
[0053] ARM ecosystem SOC 1400 may also include a subscriber identity module (SIM) l/F 1430, a boot read-only memory (ROM) 1435, a synchronous dynamic random access memory (SDRAM) controller 1440, a flash controller 1445, a serial peripheral interface (SPI) master 1450, a suitable power control 1455, a dynamic RAM (DRAM) 1460, and flash 1465. In addition, one or more example embodiments include one or more communication capabilities, interfaces, and features such as instances of Bluetooth™ 1470, a 3G modem 1475, a global positioning system (GPS) 1480, and an 802.11 Wi-Fi 1485.
[0054] In operation, the example of FIGURE 14 can offer processing capabilities, along with relatively low power consumption to enable computing of various types (e.g., mobile computing, high-end digital home, servers, wireless infrastructure, etc.). In addition, such an architecture can enable any number of software applications (e.g., Android™, Adobe® Flash® Player, Java Platform Standard Edition (Java SE), JavaFX, Linux, Microsoft Windows Embedded, Symbian and Ubuntu, etc.). In at least one example embodiment, the core processor may implement an out-of-order superscalar pipeline with a coupled low-latency level-2 cache.
[0055] FIGURE 15 illustrates a processor core 1500 according to an embodiment. Processor core 1500 may be the core for any type of processor, such as a micro-processor, an embedded processor, a digital signal processor (DSP), a network processor, or other device to execute code. Although only one processor core 1500 is illustrated in Figure 15, a processor may alternatively include more than one of the processor core 1500 illustrated in Figure 15. For example, processor core 1500 represents one example embodiment of processors cores 1374a, 1374b, 1374a, and 1374b shown and described with reference to processors 1370 and 1380 of FIGURE 13. Processor core 1500 may be a single-threaded core or, for at least one embodiment, processor core 1500 may be multithreaded in that it may include more than one hardware thread context (or "logical processor") per core.
[0056] FIGURE 15 also illustrates a memory 1502 coupled to processor core 1500 in accordance with an embodiment. Memory 1502 may be any of a wide variety of memories (including various layers of memory hierarchy) as are known or otherwise available to those of skill in the art. Memory 1502 may include code 1504, which may be one or more instructions, to be executed by processor core 1500. Processor core 1500 can follow a program sequence of instructions indicated by code 1504. Each instruction enters a front- end logic 1506 and is processed by one or more decoders 1508. The decoder may generate, as its output, a micro operation such as a fixed width micro operation in a predefined format, or may generate other instructions, microinstructions, or control signals that reflect the original code instruction. Front-end logic 1506 also includes register renaming logic 1510 and scheduling logic 1512, which generally allocate resources and queue the operation corresponding to the instruction for execution.
[0057] Processor core 1500 can also include execution logic 1514 having a set of execution units 1516-1 through 1516-N. Some embodiments may include a number of execution units dedicated to specific functions or sets of functions. Other embodiments may include only one execution unit or one execution unit that can perform a particular function. Execution logic 1514 performs the operations specified by code instructions. [0058] After completion of execution of the operations specified by the code instructions, back-end logic 1518 can retire the instructions of code 1504. In one embodiment, processor core 1500 allows out of order execution but requires in order retirement of instructions. Retirement logic 1520 may take a variety of known forms (e.g., reorder buffers or the like). In this manner, processor core 1500 is transformed during execution of code 1504, at least in terms of the output generated by the decoder, hardware registers and tables utilized by register renaming logic 1510, and any registers (not shown) modified by execution logic 1514.
[0059] Although not illustrated in FIGURE 15, a processor may include other elements on a chip with processor core 1500, at least some of which were shown and described herein with reference to FIGURE 13. For example, as shown in FIGURE 13, a processor may include memory control logic along with processor core 1500. The processor may include I/O control logic and/or may include I/O control logic integrated with memory control logic.
[0060] Note that with the examples provided herein, interaction may be described in terms of two, three, or more network elements. However, this has been done for purposes of clarity and example only. In certain cases, it may be easier to describe one or more of the functionalities of a given set of flows by only referencing a limited number of network elements. It should be appreciated that communication system 100 and and their teachings are readily scalable and can accommodate a large number of components, as well as more complicated/sophisticated arrangements and configurations. Accordingly, the examples provided should not limit the scope or inhibit the broad teachings of communication system 100 and as potentially applied to a myriad of other architectures.
[0061] It is also important to note that the operations in the preceding flow diagrams (i.e., FIGURES 8-12) illustrate only some of the possible correlating scenarios and patterns that may be executed by, or within, communication system 100. Some of these operations may be deleted or removed where appropriate, or these operations may be modified or changed considerably without departing from the scope of the present disclosure. In addition, a number of these operations have been described as being executed concurrently with, or in parallel to, one or more additional operations. However, the timing of these operations may be altered considerably. The preceding operational flows have been offered for purposes of example and discussion. Substantial flexibility is provided by communication system 100 in that any suitable arrangements, chronologies, configurations, and timing mechanisms may be provided without departing from the teachings of the present disclosure.
[0062] Although the present disclosure has been described in detail with reference to particular arrangements and configurations, these example configurations and arrangements may be changed significantly without departing from the scope of the present disclosure. Moreover, certain components may be combined, separated, eliminated, or added based on particular needs and implementations. Additionally, although communication system 100 have been illustrated with reference to particular elements and operations that facilitate the communication process, these elements and operations may be replaced by any suitable architecture, protocols, and/or processes that achieve the intended functionality of communication system 100.
[0063] Numerous other changes, substitutions, variations, alterations, and modifications may be ascertained to one skilled in the art and it is intended that the present disclosure encompass all such changes, substitutions, variations, alterations, and modifications as falling within the scope of the appended claims. In order to assist the United States Patent and Trademark Office (USPTO) and, additionally, any readers of any patent issued on this application in interpreting the claims appended hereto, Applicant wishes to note that the Applicant: (a) does not intend any of the appended claims to invoke paragraph six (6) of 35 U.S.C. section 112 as it exists on the date of the filing hereof unless the words "means for" or "step for" are specifically used in the particular claims; and (b) does not intend, by any statement in the specification, to limit this disclosure in any way that is not otherwise reflected in the appended claims.
