Snoring can disturb another person who is sleeping in the same room. Snoring can be particularly disturbing if the snorer and the other person are attempting to sleep on the same bed, such as a married couple where one spouse snores. Some people deal with the problem by waking the snorer up in order to stop the snoring. However, the snorer often begins snoring again after going back to sleep. Moreover, waking the snorer interrupts the snorers sleep as well.
The present disclosure is directed to a sleep system and method that allows a first occupant on an adjustable bed to select a position for an opposite side of the bed. For example, if a second occupant on the opposite side of the bed is snoring, the first occupant can control the opposite side to move into a snore-reducing position. The first occupant can activate the snore-reducing position without having to wake the second occupant. The ability to control the position of the opposite side of the bed can be incorporated into a remote control or other controlling device that is accessible by the first occupant so that the second occupant's side of the bed can be actuated by the first occupant's remote control or other controlling device. This feature can allow the first occupant to reduce or eliminate the second occupant's snoring easily without the first occupant having to wake the second occupant and disturb his or her sleep.
The present disclosure describes a sleep system comprising at least one mattress including a first sleep area for a first occupant, the first sleep area including a first section for a portion of a body of the first occupant, and a second sleep area adjacent to the first sleep area for a second occupant, the second sleep area including a second section for a portion of a body of the second occupant, an articulation system for articulating the first section and the second section, a first user controller configured to communicate with the articulation system in order to control articulation of the first section, and a second user controller configured to communicate with the articulation system in order to control articulation of the second section, wherein the first user controller is further configured to communicate with the articulation system in order to move the second section into a predetermined position.
The present disclosure also describes a sleep system, comprising a support frame, at least one mattress configured to be positioned on the support frame, the at least one mattress including, a first sleep area for a first occupant, the first sleep area including an articulable first head section and an articulable first leg section, and a second sleep area adjacent to the first sleep area for a second occupant, the second sleep area including an articulable second head section and an articulable second leg section. The sleep system further comprises an articulation system including a first head motor for articulating the first head section, a first leg motor for articulating the first leg section, a second head motor for articulating the second head section, a second leg motor for articulating the second leg section, and at least one controller for controlling the first head motor, the first leg motor, the second head motor, and the second leg motor. The sleep system also includes a first user controller configured to communicate with the at least one controller via a first communication link in order to control articulation of the first head section to a plurality of positions and to control the first leg section to a plurality of positions and a second user controller configured to communicate with the at least one controller via a second communication link in order to control articulation of the second head section to a plurality of positions and to control the second leg section to a plurality of positions. The first user controller is further configured to communicate with the at least one controller in order to move the second head section to a predetermined position.
The present disclosure further describes a method for controlling an articulating bed, the method comprising sending a first movement control signal from a first user controlling device to one or more controllers, wherein the first movement control signal comprises one or more commands to move a first sleep area to any of a plurality of positions, sending a first motor control signal, triggered by the first movement control signal, from the one or more controllers to a first set of one or more articulating motors, moving the first sleep area to one of the plurality of positions according to the first motor control signal with the first set of one or more articulating motors, sending a second movement control signal from the first user controlling device to the one or more controllers, wherein the second movement control signal comprises one or more commands to move a second sleep area to a predetermined position, sending a second motor control signal, triggered by the second movement control signal, from the one or more controllers to a second set of one or more articulating motors, and moving the second sleep area to the predetermined position according to the second motor control signal with the second set of one or more articulating motors.
These and other examples and features of the present systems and methods will be set forth in part in the following Detailed Description. This Summary is intended to provide an overview of the present subject matter, and is not intended to provide an exclusive or exhaustive explanation. The Detailed Description below is included to provide further information about the present systems and methods.
This disclosure describes a sleep system including an adjustable bed configured for two occupants to share. The adjustable bed can be configured so that each side of the bed can be independently adjusted by each occupant of the bed, e.g., so that each occupant can select a particular position or positions that he or she prefers. Each side of the bed can be independently controlled by a controlling device, such as a remote control, so that each occupant has individual control over their side of the bed. The sleep system can be configured so that a first occupant's remote control can control the position of one or more aspects of the second occupant's side of the bed. For example, the sleep system can be configured so that if one of the occupants begins to snore, the snoring occupant's partner can use their own remote to adjust the snoring occupant's side of the bed into a snore-reducing position.
Each of the sleep areas 20, 22 can be movable or articulable between a plurality of positions to provide the occupants 14, 16 with the ability to select a preferred position for comfort of for a particular purpose. Each sleep area 20, 22 can include one or more articulable sections. In an example, the first sleep area 20 can include a section 24 that can be raised and lowered to adjust a position of the head or upper torso, or both, of the first occupant 14 (referred to herein as the first head section 24) and a section 26 that can be raised and lowered to adjust a position of the legs or lower torso, or both, of the first occupant 14 (referred to herein as the first leg section 26). Similarly, the second sleep area 22 can include a section 28 that can be raised and lowered to adjust a position of the head or upper torso, or both, of the second occupant 16 (referred to herein as the second head section 28) and a section 30 that can be raised and lowered to adjust a position of the legs or lower torso, or both, of the second occupant 16 (referred to herein as the second leg section 30).
Examples of adjustable beds that are similar to the articulable sleep areas of the present disclosure include, but are not limited to, Sleep Number Split King or Split Queen beds, sold by Select Comfort Corp., Minneapolis, Minn., or the Queen Split, California King Split, or Eastern King Split mattresses sold by Comfortaire Corp., Greenville, S.C. Other sizes of split-type articulating mattress, other than queen and king size mattresses, can be used without varying from the scope of the present disclosure.
In the example best seen in
The sleep system 10 can also include a pair of user controlling devices 32, 34 to allow each occupant 14, 16 to control the articulation of his or her respective sleep area 20, 22. As shown in
Each head section 24, 28 and each leg section 26, 30 can be independently articulated. For example, the first occupant 14 can select, via the first remote control 32, to articulate the first head section 24 upward or downward by a certain amount or to articulate the first leg section 26 upward or downward by a certain amount. In an example, the head sections 24, 28 and the leg sections 26, 30 can be independently controlled by the remote controls 32, 34, e.g., continuously or along a discrete set of positions between a minimum height or orientation and a maximum height or orientation. The head section 24, 28 and the leg section 26, 30 can be articulable from a minimum height position (e.g., flat) to a maximum height position (e.g., with the head section 24, 28 at a maximum angle with respect horizontal, such as about 60°, or with the leg section 26, 30 at a maximum angle with respect to horizontal, such as about 45°)
The sleep system 10 can also be configured so that the sleep areas 20, 22 can be positioned into one or more predetermined or preset positions. For each preset position, the head section 24, 28 and the leg section 26, 30 can be moved to predetermined positions or orientations. Examples of preset positions that can each be programmed into the sleep system 10 include, but are not limited to:
In an example, a preset position can be a snore-reducing or snore-eliminating position. Snoring can be caused by soft tissue in the back of the mouth or the throat that relaxes during sleep. The relaxed soft tissue can partially block the snorer's airway. The snorer's body typically reacts by breathing harder, which can cause the soft tissue to vibrate and cause a snoring sound. It has been found that, in some cases, snoring can be reduced or prevented by elevating the snorer's head or torso by a small amount, which can reduce vibration of the soft tissue. The slight elevation of the snorer's body can also induce the snorer to change his or her sleeping position, which can cause the snoring to stop. Therefore, in an example, a “snore-reducing” preset can comprise the head section 24, 28 being elevated slightly relative to the leg section 26, 30 (for example, less than the “reading” preset or the “television” preset) in order to reduce or alleviate snoring by the occupant 14, 16 laying on the sleep area 20, 22 being articulated. In an example, the snore-reducing preset can include the head section 24, 28 being raised at a preset angle θ relative to horizontal, as shown with head section 28 in
The articulation system 40 can also include one or more controllers, such as a control box that includes the electronics and hardware for providing instructions to the articulating motors 42, 44, 46, 48.
The controller 50 can send one or more motor control signals to the articulating motors 42, 44, 46, 48 corresponding to a desired motion of the articulating motors 42, 44, 46, 48. A “motor control signal,” as used herein, can refer to a signal or plurality of signals sent from a controller, such as the controller 50, to one or more articulating motors 42, 44, 46, 48 corresponding to a particular movement or position of one or more articulable sections 24, 26, 28, 30. A motor control signal or signals can comprise an instruction for one or both of the direction that the articulating motor 42, 44, 46, 48 should articulate and the speed that the articulating motor 42, 44, 46, 48 should travel. In an example, a plurality of communication cables 56A, 56B, 56C, 56D (collectively referred to herein as “cable 56” or “cables 56”) can carry the motor control signals from the controller 50 to the articulating motors 42, 44, 46, 48, with each cable 56 corresponding to a particular motor (such as a first cable 56A for the first head motor 42, a second cable 56B for the first leg motor 44, a third cable 56C for the second head motor 46, and a fourth cable 56D for the second foot motor 48).
In another example, a sleep system 60 can include an articulating system 62 having more than a single common controller. In the example shown in
The separate controllers 64A, 64B (collectively referred to herein as “controller 64” or “controllers 64”) can each be in communication with one of the remote controls 32, 34 or configured to respond to the commands sent from only one of the remote controls 32, 34. For example, the first controller 64A can be linked to the first remote control 32 via a first wireless communication link 52 and the second controller 64B can be linked to the second remote control 34 via a second wireless communication link 54. Each separate controller 64 can include communication links, such as cables, to the articulating motors 42, 44, 46, 48 that are controlled by that particular controller 64. For example, the first controller 64A can be linked to the first head motor 42 via a first cable 66A and to the first leg motor 44 via a second cable 66B. Similarly, the second controller 64B can be linked to the second head motor 46 via a first cable 68A and to the second leg motor 48 via a second cable 68B. The controllers 64A and 64B can be in communication with each other via a communication link, such as a cable 69 running between the controllers 64A, 64B to pass control signals between the controllers 64A, 64B.
The controller 70 can include communication modules to allow the controller 70 to communicate with the remote controls 32, 34 and the articulating motors 42, 44, 46, 48, such as a telemetry module 72 and a communication bus 74. The telemetry module 72 can allow for the wireless transfer of data, such as control signals, to and from one or both of the remote controls 32, 34 by establishing a wireless communication link 52, 54 between the telemetry module 72 and a similar corresponding telemetry module within each remote control 32, 34. The telemetry module 72 can include a radio frequency (RF) transceiver to permit bi-directional communication between the controller 70 and the remote controls 32, 34. To support wireless communication, such as RF communication, the telemetry module 72 can include appropriate electrical components, such as one or more of amplifiers, filters, mixers, encoders, decoders, and the like.
The communication bus 74 can provide for a physical communication link to the controller 70, such as via one or more cables 76A, 76B, 76C, 76D (collectively “cable 76” or “cables 76”), which can correspond to the cables 56 from the controller 50 in
Each port 78 can be addressed to correspond to a particular communication link that is to be established. For example, in the case of the single controller 50 of
The controller 70 can also include a processor 80, a memory 82, and a power source 84. The processor 80 can control the overall operation of the controller 70, such as by storing and retrieving information from the memory 82, by controlling transmission of signals to and from the remote controls 32, 34 via the telemetry module 72, and controlling transmission of signals to and from the articulating motors 42, 44, 46, 48 or another controller via the communication bus 74. The processor 80 can take the form of one or more microprocessors, one or more controllers, one or more digital signal processor (DSP), one or more application-specific integrated circuit (ASIC), one or more field-programmable gate array (FPGA), or other digital logic circuitry.
The memory 82 can store instructions for execution by the processor 80, such as predetermined control instructions for the articulating motors 42, 44, 46, 48. The memory 82 can also store information corresponding to the operation of the sleep system 10, such as storing addresses identifying each remote control 32, 34 or each articulating motor 42, 44, 46, 48. The memory 82 can also store other information regarding the components of the sleep system 10, such as the present configuration of each articulable section 24, 26, 28, 30, or the present position of each articulating motor 42, 44, 46, 48, or both. The memory 82 can also store preset positions of each articulable section 24, 26, 28, 30 or each articulating motor 42, 44, 46, 48, or both, with each preset position corresponding to a particular preset position of the sleep areas 20, 22 (as described in more detail above). The memory 82 can include any electronic data storage media, such as any one or more of random access memory (RAM), read-only memory (ROM), electronically-erasable programmable ROM (EEPROM), flash memory, and the like.
Alternatively, or in conjunction with the memory 82, the sleep system 10 can include one or more positional sensors configured to determine a position or orientation of each of the articulable sections 24, 26, 28, 30 or each of the articulating motors 42, 44, 46, 48, or both. The one or more positional sensors can transmit the position or orientation of each articulable section 24, 26, 28, 30 or each articulating motor 42, 44, 46, 48, or both, to the controller 70. Examples of positional sensors that can be used with the sleep systems of the present disclosure include, but are not limited to, accelerometers and gyroscope positional or orientation sensors. Alternatively, a sensor can be included on the motors 42, 44, 46, 48, such as a motor encoder, to determine a position of the motor or an actuater moved by the motor. Other types of positional or orientation sensors can be used.
The power source 84 can comprise power circuitry that is connectable to an external power supply, such as a standard alternating current (AC) power supply. The power source 84 can also include a battery, such as a non-rechargeable primary cell battery or a rechargeable battery, which can be coupled to the power circuitry.
As described above, each sleep area 20, 22 can be controlled by a corresponding remote control 32, 34, such as the first remote control 32 controlling the first sleep area 20 and the second remote control 34 controlling the second sleep area 22. As further described above, the sleep system 10 can be configured so that the first remote control 32 is linked to the first sleep area 20, e.g., so that when the first occupant 14 selects a movement command on the first remote control 32, the articulation system 40 correctly articulates the first sleep area 20 occupied by the first occupant 14 rather than the second sleep area 22 occupied by the second occupant 16. Similarly, the sleep system 10 can be configured so that the second remote control 34 is linked to the second sleep area 22.
In order to ensure proper linking between each remote control 32, 34 and the corresponding sleep area 20, 22, each remote control 32, 34 can have an address or other unique identifier. The address can allow the controller 70 (e.g., the controller 50 or the controllers 64A, 64B) to identify which remote control 32, 34 is sending a movement control signal. For example, when the first remote control 32 sends a movement control signal to the controller 70, the movement control signal can include a header that includes the address for the first remote control 32. Upon receiving the movement control signal, the controller 70 can read the header including the address and determine that the movement control signal came from the first remote controller 32. The controller 70 can then determine that the movement control signal should correspond to the first sleep area 20, and the controller 70 can relay a corresponding motor control signal or signals to the first head motor 42 or the first leg motor 44, or both. Similarly, when the second remote control 34 sends a movement control signal to the controller 70, the movement control signal can include a header with the address for the second remote control 34. The controller 70 can then send a corresponding control signal to the second head motor 46 or to the second leg motor 48, or both.
Each remote control 32, 34 can be configured to allow an occupant 14, 16 operating the remote control 32, 34 to select a specific, desired movement of the sleep system 10. Selection of the desired movement by the occupant 14, 16 can, in turn, trigger a corresponding movement control signal to be sent from the remote control 32, 34 to the controller 70. Examples of movements that can be selected by an occupant 14, 16 on each remote control 32, 34 can include, but are not limited to, at least one of the following commands: raise a first section, e.g., a command to raise a head section 24, 28; lower a first section, e.g., a command to lower a head section 24, 28; raise a second section, e.g., a command to raise a leg section 26, 30; lower a second section, e.g., a command to lower a leg section 26, 30; move one or both of the first section and the second section into a preset position, such as a flat position, a reading position, a “watch TV” position, and so forth.
Each command can be activated by activating a particular button, series of buttons, or series of menu selections, on the remote control 32, 34. Each button or menu selection can be a physical button or can be a virtual button, such as a button on a touch screen, or a series of button presses or menu prompts that are entered through physical or virtual buttons.
As noted above, each remote control 32, 34 can be configured to control the articulation of the articulable sections 24, 26, 28, 30 of a corresponding sleep area 20, 22. In other words, each occupant 14, 16 can control the articulation of his or her own sleep area 20, 22. For example, as described above, the first remote control 32 can be linked to the first sleep area 20, e.g., so that the first occupant 14 can control articulation of the first sleep area 20 upon which the first occupant 14 is resting. Similarly, the second remote control 34 can be linked to the second sleep area 22, e.g., so that the second occupant 16 can control articulation of the second sleep area 22 upon which the second occupant 16 is resting.
In an example, one or both of the remote controls 32, 34 can be configured to not only control articulation of a corresponding sleep area 20, 22, but can also be configured to control one or more specific aspects of articulation of the opposite sleep area 20, 22. For example, while the first remote control 32 can be configured to provide total control over articulation of the first sleep area 20, the first remote control 32 can also be configured to move the second sleep area 22 into a specific, predetermined position or preset.
In one configuration, the first remote control 32 can be configured to place the second sleep area 22 into a snore-reducing preset position (described above). For example, the first remote control 32 can be configured so that if the first occupant 14 selects a particular button, a particular button sequence, or a particular menu sequence on the first remote control 32, then the second sleep area 22 will be articulated into the snore-reducing position. Similarly, the second remote control 34 can be configured so that if the second occupant 16 selects a particular button, button sequence, or menu sequence, then the first sleep area 20 will be articulated into the snore-reducing position. For the purposes of brevity, the remainder of this disclosure will describe the first remote control 32 being configured to adjust the second sleep area 22. However, it is to be understood that a similar configuration could be applied to the second remote control 34 controlling the first sleep area 20 without varying from the scope of the present disclosure.
In an example, the first remote control 32 can be configured to allow for full intended control of the articulation of the first sleep area 20 by the first occupant 14, while only allowing the first remote control 32 to select the predetermined position (e.g., the snore-reducing position) of the second sleep area 22.
In an example, when the first remote control 32 is being used by the first occupant 14 to control the articulation of the first sleep area 20 (e.g., the sleep area upon which the first occupant 14 is resting), then the controller 50, 64A can be configured to move the articulation motors 42, 44 of the first sleep area 20 at a first speed. However, when the first remote control 32 is being used by the first occupant 14 to move the second sleep area 22 into the predetermined position or preset, the controller 50, 64B can be configured to move the articulation motors 46, 48 of the second sleep area 22 at a second speed that is different than the first speed. The second speed can also be different than the speed at which the motors 46,48 would move if the second occupant 16 had used the second remote control 34 to select the same predetermined position or preset.
In an example, the second speed of the motors 46, 48 can be slower than the first speed. A slower second speed can be desirable because, as described above, the second occupant 16 can be asleep, and a slower speed can prevent or reduce the likelihood of the second occupant 16 waking up as the second sleep area 22 is moved to the predetermined position or preset. For example, if a “Partner Snore” feature is implemented, then the first occupant 14 can be selecting the snore-reducing position because the second occupant 16 is snoring, and therefor asleep, on the second sleep area 22.
At 104, the first remote control 32 can send a movement control signal to one or more controllers, such as the single controller 50 (
In the case of the “Partner Snore” control signal, wherein the first controller 32 has sent a movement control signal to move the second sleep area 22 into the snore-reduction position, then the movement control signal can include an indication that the movement is for the opposite sleep area from the remote control 32, 34 that sent the movement control signal. For example, the movement control signal can come from the first remote control 32, but can include a movement control signal configured to articulate motion of one or more sections of the second sleep area 22, such as a control signal configured to cause the second head motor 46 to articulate the second head section 28 to the snore-reducing angle θ relative to horizontal, as described above.
At 106, the one or more controllers 50, 64A, 64B receive the movement control signal and determine what action to take. Determining what action to take can include the controller 50, 64A, 64B determining which remote control 32, 34 sent the movement control signal, for example by analyzing the header and reading the address contained therein. The controller 50, 64A, 64B can then determine whether the movement control signal is intended for itself, or for another controller 50, 64A, 64B. In the case of a single controller 50, each movement control signal is intended for the controller 50 unless a remote control from another sleep system is being used. However, when more than one controller 64A, 64B is included, as in
At 108, the one or more controllers 50, 64A, 64B can formulate a motor control signal or signals that are to be sent to one or more of the articulating motors 42, 44, 46, 48. The motor control signal or signals for each articulating motor 42, 44, 46, 48 can include what action the articulating motor 42, 44, 46, 48 should take, such as what direction the articulating motor 42, 44, 46, 48 should move, at what speed, and for how long. The motor control signal or signals can also include the timing and order of the actions that each articulating motor 42, 44, 46, 48 is to take. In the case of two or more controllers 64A, 64B, the controller 64A, 64B that receives the movement control signal can determine which remote control 32, 34 sent the movement control signal, such as by analyzing the address within the movement control signal, and what articulable section or sections 24, 26, 28, 30 to which the movement control signal is directed. The controller 64A, 64B can then determine whether to send a motor control signal directly to an articulating motor 42, 44, 46, 48 over which the controller 64A, 64B has direct control, or to send the motor control signal to the other controller 64A, 64B, such as via the cable 69.
For example, if the first controller 64A receives a movement control signal from the first remote control 32 indicating that the first head section 24 or the first leg section 26, or both, should be articulated, then the controller 64A can determine that a motor control signal can be sent directly to the first head motor 42 or the first leg motor 44, or both. Conversely, if the first controller 64A receives a movement control signal from the first remote control 32 indicating that the second head section 28 or the second leg section 30, or both, should be articulated (e.g., to move the second sleep area 22 into the snore-reducing position), then the controller 64A can send a control signal to the second controller 64B, via the cable 69, that will trigger the second controller 64B to formulate one or more appropriate motor control signals for the second head motor 46 or the second leg motor 48, or both.
At 110, the one or more controllers 50, 64A, 64B send the one or more motor control signals to the appropriate articulating motor or motors 42, 44, 46, 48, such as via the cables 56, 66, or 68. In an example, the motor control signal can include an address or unique identifier corresponding to the articulating motor 42, 44, 46, 48 to which the control signal is being directed. The address can be placed in a header of the control signal, similar to the address for the remote controls 32, 34 in the movement control signals described above.
In the case of a “Partner Snore” signal that was sent from the first controller 32, the controller 50 or 64B can send a motor control signal to the second head motor 46 that will move the second head section 28 to be at the snore-reducing angle θ, described above. The controller 50 or 64B can also send a motor control signal to the second leg motor 48 to move the second led section 30 into a flat position, e.g., a horizontal or substantially horizontal position.
In an example, before sending a signal to the articulating motors 42, 44, 46, 48, the controller 50 or 64B can determine the current position of each section 28, 30 of the second sleep area 22. For example, after accessing the current positions of the second head section 28 and the second leg section 30 from the memory of the controller 50, 64B (e.g., the memory 82 of controller 70 described above with respect to
At 112, the motor control signal or signals are received by one or more of the articulating motors 46, 48 associated with the second sleep area 22, e.g., the second head motor 46 and the second leg motor 48. At 114, each motor 46, 48 can then articulate a corresponding section (e.g., the second head section 28 being articulated by the second head motor 46 and the second leg section 30 being articulated by the second head motor 48) so that the second sleep area is moved into the desired position, e.g., the snore-reducing position.
The ability for the first remote control 32 to move the second sleep area 22 into a predetermined position, such as the snore-reducing position, can have advantages that are not realized in other sleep systems. For example, such a configuration can allow the first occupant 14 who is being disturbed by the snoring of the second occupant 16 to reduce or alleviate the snoring by simply selecting an option on the first remote control 32, which presumably can be conveniently located relative to the first occupant 14 because the first remote control 32 is also configured to control the first sleep area 20. The use of the first remote control 32 to adjust the second sleep area 22 can provide a convenient and effective solution to the first occupant 14.
Such a configuration can also allow the first occupant 14 to reduce or eliminate the snoring of the second occupant 16 without having to disturb the sleep of the second occupant 16, e.g., without having to wake or otherwise disturb the second occupant 16. Thus, the sleep systems of the present disclosure can provide for a better sleep experience for the second occupant 16.
The configuration described herein can also provide a more lasting solution to snoring by the second occupant 16. As noted above, previously, the first occupant 14 might attempt to remedy the snoring of the second occupant 16 by waking the second occupant 16. The awakened second occupant 16 may temporarily cease snoring, but often the snoring will continue once the second occupant 16 goes back to sleep because the bed upon which the second occupant 16 is sleeping is still in the same snore-inducing position as before. The systems 10, 60 of the present disclosure allow the first occupant 14 to reduce or eliminate snoring of their partner by placing the second sleep area 22 into a different position than it was when the second occupant 16 began snoring. Thus, the systems 10, 60 of the present disclosure can be more likely to reduce or eliminate snoring
The above Detailed Description is intended to be illustrative, and not restrictive. For example, the above-described examples (or one or more elements thereof) can be used in combination with each other. Other embodiments can be used, such as by one of ordinary skill in the art upon reviewing the above description. Also, various features or elements can be grouped together to streamline the disclosure. This should not be interpreted as intending that an unclaimed disclosed feature is essential to any claim. Rather, inventive subject matter can lie in less than all features of a particular disclosed embodiment. Thus, the following claims are hereby incorporated into the Detailed Description, with each claim standing on its own as a separate embodiment. The scope of the invention should be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled.
In the event of inconsistent usages between this document and any documents so incorporated by reference, the usage in this document controls.
In this document, the terms “a” or “an” are used, as is common in patent documents, to include one or more than one, independent of any other instances or usages of “at least one” or “one or more.” In this document, the term “or” is used to refer to a nonexclusive or, such that “A or B” includes “A but not B,” “B but not A,” and “A and B,” unless otherwise indicated. In this document, the terms “including” and “in which” are used as the plain-English equivalents of the respective terms “comprising” and “wherein.” Also, in the following claims, the terms “including” and “comprising” are open-ended, that is, a system, device, article, composition, formulation, or process that includes elements in addition to those listed after such a term in a claim are still deemed to fall within the scope of that claim. Moreover, in the following claims, the terms “first,” “second,” and “third,” etc. are used merely as labels, and are not intended to impose numerical requirements on their objects.
Method examples described herein can be machine or computer-implemented, at least in part. Some examples can include a computer-readable medium or machine-readable medium encoded with instructions operable to configure an electronic device to perform methods or method steps as described in the above examples. An implementation of such methods or method steps can include code, such as microcode, assembly language code, a higher-level language code, or the like. Such code can include computer readable instructions for performing various methods. The code may form portions of computer program products. Further, in an example, the code can be tangibly stored on one or more volatile, non-transitory, or non-volatile tangible computer-readable media, such as during execution or at other times. Examples of these tangible computer-readable media can include, but are not limited to, hard disks, removable magnetic disks, removable optical disks (e.g., compact disks and digital video disks), magnetic cassettes, memory cards or sticks, random access memories (RAMs), read only memories (ROMs), and the like.
The Abstract is provided to comply with 37 C.F.R. §1.72(b), to allow the reader to quickly ascertain the nature of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
Although the invention has been described with reference to exemplary embodiments, workers skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the invention.
