A more particular description of the embodiments briefly described above will be rendered by reference to specific embodiments that are illustrated in the appended drawings. Understanding that these drawings depict only some embodiments and are not therefore to be limiting of scope, the embodiments will be described and explained with additional specificity and detail using the accompanying drawings, in which:
As will be appreciated by one skilled in the art, aspects of the embodiments may be embodied as a system, method, or program product. Accordingly, embodiments may take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, micro-code, etc.) or an embodiment combining software and hardware aspects that may all generally be referred to herein as a “circuit,” “module” or “system.” Furthermore, embodiments may take the form of a program product embodied in one or more computer readable storage devices storing machine readable code, computer readable code, and/or program code, referred hereafter as code. The storage devices may be tangible, non-transitory, and/or non-transmission. The storage devices may not embody signals. In a certain embodiment, the storage devices only employ signals for accessing code.
Many of the functional units described in this specification have been labeled as modules, to emphasize their implementation independence more particularly. For example, a module may be implemented as a hardware circuit comprising custom very large scale integrated (VLSI) circuits or gate arrays, off-the-shelf semiconductors such as logic chips, transistors, or other discrete components. A module may also be implemented in programmable hardware devices such as a field programmable gate array (FPGA), programmable array logic, programmable logic devices or the like.
Modules may also be implemented in code and/or software for execution by various types of processors. An identified module of code may, for instance, comprise one or more physical or logical blocks of executable code which may, for instance, be organized as an object, procedure, or function. Nevertheless, the executables of an identified module need not be physically located together but may comprise disparate instructions stored in different locations which, when joined logically together, comprise the module and achieve the stated purpose for the module.
Indeed, a module of code may be a single instruction, or many instructions, and may even be distributed over several different code segments, among different programs, and across several memory devices. Similarly, operational data may be identified and illustrated herein within modules and may be embodied in any suitable form and organized within any suitable type of data structure. The operational data may be collected as a single data set or may be distributed over different locations including over different computer readable storage devices. Where a module or portions of a module are implemented in software, the software portions are stored on one or more computer readable storage devices.
Any combination of one or more computer readable medium may be utilized. The computer readable medium may be a computer readable storage medium. The computer readable storage medium may be a storage device storing the code. The storage device may be, for example, but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, holographic, micromechanical, or semiconductor system, apparatus, or device, or any suitable combination of the foregoing.
More specific examples (a non-exhaustive list) of the storage device would include the following: an electrical connection having one or more wires, a portable computer diskette, a hard disk, a random-access memory (RAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM or Flash memory), a portable compact disc read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing. In the context of this document, a computer readable storage medium may be any tangible medium that can contain or store a program for use by or in connection with an instruction execution system, apparatus, or device.
Code for carrying out operations for embodiments may be written in any combination of one or more programming languages including an object-oriented programming language such as Python, Ruby, R, Java, Java Script, Smalltalk, C++, C sharp, Lisp, Clojure, PHP, or the like, and conventional procedural programming languages, such as the “C” programming language, or the like, and/or machine languages such as assembly languages. The code may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Surface Provider).
The embodiments may transmit data between electronic devices. The embodiments may further convert the data from a first format to a second format, including converting the data from a non-standard format to a standard format and/or converting the data from the standard format to a non-standard format. The embodiments may modify, update, and/or process the data. The embodiments may store the received, converted, modified, updated, and/or processed data. The embodiments may provide remote access to the data including the updated data. The embodiments may make the data and/or updated data available in real time. The embodiments may generate and transmit a message based on the data and/or updated data in real time. The embodiments may securely communicate encrypted data. The embodiments may organize data for efficient validation. In addition, the embodiments may validate the data in response to an action and/or a lack of an action.
Reference throughout this specification to “one embodiment,” “an embodiment,” or similar language means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, appearances of the phrases “in one embodiment,” “in an embodiment,” and similar language throughout this specification may, but do not necessarily, all refer to the same embodiment, but mean “one or more but not all embodiments” unless expressly specified otherwise. The terms “including,” “comprising,” “having,” and variations thereof mean “including but not limited to,” unless expressly specified otherwise. An enumerated listing of items does not imply that any or all of the items are mutually exclusive, unless expressly specified otherwise. The terms “a,” “an,” and “the” also refer to “one or more” unless expressly specified otherwise.
As used herein, a list with a conjunction of “and/or” includes any single item in the list or a combination of items in the list. For example, a list of A, B and/or C includes only A, only B, only C, a combination of A and B, a combination of B and C, a combination of A and C or a combination of A, B and C. As used herein, a list using the terminology “one or more of” includes any single item in the list or a combination of items in the list. For example, one or more of A, B and C includes only A, only B, only C, a combination of A and B, a combination of B and C, a combination of A and C or a combination of A, B and C. As used herein, a list using the terminology “one of” includes one and only one of any single item in the list.

Referring to
The wireless charging component 120 includes a plurality of separately controllable coils that receive power/current from a power source, such as alternating current (AC) from an AC generator or power grid or direct current (DC) from a battery or DC generator. The wireless charging component 120 is in communication with the controller 105 which controls the power sent to the separately controllable coils. The separately controllable coils are selectively activated based on the location information received from the location sensor 115, e.g., for a respective rechargeable device 140. In one embodiment, the wireless charging component 120 includes a set of coils that can be selectively activated to charge one or more rechargeable devices 140 using wireless inductive charge pattern(s). In another embodiment, the wireless charging component 120 includes a set of coils that can be selectively activated to charge one or more rechargeable devices 140 using magnetic coupling charge pattern(s) (i.e., magnetic (loose) resonant charging). While specific examples of wireless charging technologies are described, the present disclosure should not be considered limited to these specific wireless charging technologies or any specific charging protocol or standard. Rather, the solutions for wireless charging of multiple devices on a surface and providing feedback described herein apply to any known wireless charging technology and charging protocol/standard.
In various embodiments, the instructions cause the controller 105 to receive charging status information of the rechargeable device 140 via the transceiver 125. Charging status information may be any information that indicates status of a charge (e.g., percentage, stored power, or the like) of rechargeable battery(ies) included in the rechargeable device 140. Responsive to receiving the charging status information, the instructions cause the controller 105 to generate an output image or an output signal that is sent to the output device 150. In response to receiving the output image or the output signal, the output device 150 produces a human perceptible indication associated with the charge status information. The human perceptible indications are also produced in accordance with the location information of the respective rechargeable device 140 relative to the wireless charging component 120. Thus, the location information of each respective rechargeable device 140 is translated to a region or area of the output device 150, such that a respective human perceptible indication for each rechargeable device 140 is presented at/from a portion of the output device 150 that corresponds to the location of the rechargeable device 140 relative to the rechargeable device 140. Human perceptible indications include any output that can be perceived by a user—audio, visual, or tactile. In some embodiments, the output of the output device 150 may be visual indication, an audible indication, or a combination thereof.
In various embodiments, referring to
In various embodiments, the output device 150 includes a plurality of light-emitting diodes (LEDs) or other light emitting devices that are separately controllable by the controller 105. In some embodiments, the LEDs are attached to or suspended within a material that is non-conductive and magnetically permeable. In other embodiments, the output device 150 is located remote from the table apparatus 102, such as a light source or a projector configured to generate a light indication or an image at or near the location of the rechargeable device 140 on the substantially larger wireless charging component 120 in order for multiple rechargeable devices 140 to be charged simultaneously by the wireless charging component 120. As described above, the location of each light indication or image may be derived from location information corresponding to each rechargeable device 140. The output device 150 may communicate with the controller 105 via a wired or wireless connection via the transceiver 125. In some embodiments, the output device 150 may include a visual indication device (such as a display screen, a monitor, a touchscreen, virtual reality (VR) glasses, VR goggles, augmented reality (AR) glasses, AR goggles, a head mounted display (HMD)), an audio producing device (e.g., speakers), a tactile producing device (e.g., vibrator), etc. The controller 105 controls operations of the output device 150 according to location information of the rechargeable devices 140. This is described below with regard to
In various embodiments, before and/or after charging begins, a handshake communication operation may be performed between the rechargeable device 140 and the controller 105. A handshake communication operation is an automated process for information exchange between a respective rechargeable device 140 and the controller 105. In certain embodiments, the handshake communication operation occurs before charging (i.e., wireless power transfer) to verify compatibility. During the handshake communication operation, the controller 105 receives, via the transceiver 125, various information about the rechargeable device 140. The received information may include device type (e.g., smartphone, mouse, keyboard, laptop computer, etc.), make, model, dimension information, battery charge value (e.g., level of charge), amount of charge required (i.e., how much charging of the batteries is needed for the rechargeable device 140), size of charging pattern (i.e., how large a charging pattern to produce), charging speed type capability (e.g., fast or normal), and/or charging capacity. The charging pattern shape and size (i.e., power level) is determined by what coils are activated and what current level is applied to the activated coils. The device type may indicate the actual device type (e.g., smartphone, laptop) or the size, shape, number, and/or orientation of the charging components of the rechargeable device 140. Additionally, the controller 105 and/or the location sensor 115 may calculate location information of the rechargeable device 140 based on size and shape information either received directly from the rechargeable device 140 via the handshake or retrieved from a database of dimensions previously stored in the memory 110. Additional handshake communication operations may occur between the same rechargeable device 140 and the controller during charging as certain information—such as battery charge level—is expected to change as the charging operation progresses. In certain embodiments, the handshake communication operation is triggered when the controller 105 determines that an object is placed on (or above) the wireless charging component 120. Here, the handshake communication operation may be used to verify that the detected object is a rechargeable device 140. In certain embodiments, the handshake communication operation is integrated with the procedure for determining location information of a rechargeable device 140. For example, signals used to determine the location information may also be used to initiate or perform the handshake communication operation, or signals used to initiate or perform the handshake communication operation may also be used to determine the location information.
In various embodiments, the instructions cause the controller 105 to display alphanumeric characters at the output device 150. The alphanumeric characters may include a charge percentage (i.e., battery charge value) or comparable number that is presented at a location of the wireless charging component 120 next to the respective wireless charging device based on the information (e.g., battery charge value, rechargeable device information, such as shape) received from the respective rechargeable device 140 and the location information received from the location sensor 115.
In various embodiments, the rechargeable devices 140 include mobile phones, tablet computers (pad), laptop computers, palmtop computers, mobile internet devices (MID), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, personal digital assistants (PDA), handheld devices, accessory devices (including mouse, electronic stylus, and/or keyboard), computing devices or another processing devices, and/or any other suitable device configured to include wireless charging capabilities. This is not limited in embodiments of this application.
The controller 105 may include any type of processing device, such as a microprocessor, a microcontroller, a central processing unit (CPU), a graphics processing unit (GPU), an auxiliary processing unit (APU), an FPGA, another processing device, or any component capable of executing machine-readable instructions for performing data processing according to the instructions. The memory 110 may include volatile and/or non-volatile memory, examples of which may include, but are not limited to, RAM, dynamic RAM (DRAM), synchronous DRAM (SDRAM), ROM, hard disk drive (HDD) device, and/or solid-state storage (SSD) device.
