Implantable electrodes with power delivery wearable for treating sleep apnea, and associated systems and methods are disclosed herein. A representative system includes non-implantable signal generator worn by the patient and having an antenna that directs a mid-field RF power signal to an implanted electrode. The implanted electrode in turn directs a lower frequency signal to a neural target, for example, the patient's hypoglossal nerve. Representative signal generators can have the form of a mouthpiece, a collar or other wearable, and/or a skin-mounted patch.

The present specification (present disclosure) provides a method for receiving wireless power, performed by a wireless power receiver supporting a magnetic power profile (MPP), in a wireless power transmission system, and a device using same, the method comprising: transmitting a first identification (ID) packet to a wireless power transmitter on a first operating frequency, wherein the first ID packet includes information indicating the presence or absence of a first extended ID (XID) packet; transmitting the first XID packet to the wireless power transmitter on the first operating frequency, wherein the first XID packet includes information indicating that the first XID packet is a packet related to the MPP; and after transmission of the first XID packet, detecting whether the wireless power transmitter is operating on the first operating frequency or operating on a second operating frequency.

The present invention generally relates to automatic charging systems and methods for mobile devices that require more power than is possible with inductive chargers. A mobile device charging cabinet is provided, wherein each mobile device inserted for charging contains a charging receiver that is attached to a cover, such as a laptop cover. The cabinet further comprises a multiplicity of base stations, each of which provides a grid of conductive alternating polarity connection plates, spaced to accept two prongs similarly spaced on the bottom of the charging receiver. Power flows from the base station automatically through the charging receiver to the mobile device when it is placed on a surface containing a base station within the cabinet. Computer software is included to control and monitor all functionality of the system, such as optimal power flow and battery charging; and further provides key asset management tools to allow a user to know, for example, the number and exact location of all devices using the invention and under his or her control.

A method for charging a fully depleted battery of a wireless charging (WLC) device is provided. An RF controller and a read-only non-volatile memory of the WLC device is powered with the RF field of a WLC charger device. The RF controller controls charging of the battery by the RF field using a first charging program stored in the read-only non-volatile memory. A microcontroller of the WLC device is booted up after the battery has reached a predetermined voltage level. The microcontroller loads a second more complex dynamic charging program into a volatile random-access memory (RAM) of the WLC device for execution by the RF controller. The RF controller transitions code execution from the first charging program in the read-only non-volatile memory to the second charging program in the RAM. In another embodiment, the WLC device is provided.

Disclosed herein are devices (e.g., audio playback devices) configured to transmit and/or receive wireless power. Wireless power can be transferred using mid-range or long-range techniques, such as electromagnetic radiation (e.g., lasers, microwaves) or electromagnetic coupling (e.g., inductive coupling, capacitive coupling). Device performance and/or power transmission may be modified dynamically based on wireless power levels, user behavior, the behavior of other devices, device grouping, or other parameters.

An electronic apparatus obtains, from a battery, information about remaining power in the battery; detects a connection with a power supply apparatus, performs control to supply power from the power supply apparatus instead of from the battery, in a case where the connection with the power supply apparatus is detected; and displays a warning related to the remaining power in the battery when the remaining power in the battery is less than or equal to a predetermined threshold, in a case where the electronic apparatus operates using the power from the battery. In a case where the connection with the power supply apparatus is detected, the electronic apparatus displays the warning related to the remaining power in the battery when the remaining power in the battery is less than or equal to a second threshold.

A computer program product is provided according to some embodiments. The computer program product includes a non-transitory computer-readable storage medium storing a set of instructions, which, when executed by a computing device, causes the computing device to: (a) determine a discharge rate for a battery at a remote location based on a profile of the battery and a temperature value; (b) receive, at an initial time, a notification of the battery ceasing to be in communication with the computing system; (c) in response to receiving the notification, estimate an amount of time remaining until the battery self-discharges to a lower threshold state of charge (SoC); and (d) in response to elapsed time since the initial time reaching the estimated amount of time, output a signal from the computing system indicating a battery-discharge condition. A corresponding method, apparatus, and system are also provided.

The present invention relates to a method and a device for adjusting the position of coils for adaptive coupling in a wireless power transmission system. A wireless power transmission system, according to the present invention, comprises: a wireless power transmission device having a primary coil for generating a magnetic field and transmitting wireless power; and a wireless power reception device having a secondary coil for receiving the wireless power by being coupled to the primary coil, wherein the wireless power transmission device sequentially emits search pings while moving the primary coil, receives a signal strength packet that corresponds to each search ping, and moves the primary coil to a target position in which the coupling degree of the primary coil and secondary coil is equal to or higher than a fixed threshold value or is relatively the highest.

A transmitter device includes a signaling modulation module, an energy modulation module, and an antenna element. The signaling modulation module is configured to generate a narrowband modulation signal that carries signaling. The signaling includes an indication for a correspondence between a first resource and a receiver device. The first resource is scheduled based on a pre-received charging request signal from the receiver device. The energy modulation module is configured to perform amplitude and phase adjustment on the narrowband modulation signal based on the pre-received charging request signal to form an energy transmission signal. The antenna element is configured to transmit the energy transmission signal on the first resource to charge one or more receiver devices.

Embodiment herein disclose a method performed a network node for energy harvesting. The transmitter, the receiver unit operate in the network node. The receiver unit is positioned at a distance d from the transmitter to produce a first amount of electrical energy. Further, the performance parameters are collected by a control unit from at least one wireless device to determine a preferred distance required between the receiver unit and the transmitter. Thereafter, the position of the receiver unit is adjusted by the control unit, at the preferred distance to the transmitter to harvest a second amount of electrical energy, where second amount is greater than the first amount. Further, at least one of the first amount or second amount of electrical energy harvested by the receiver unit is stored in a power distribution unit.
