Embodiments presented herein are generally directed to techniques for separately transferring power and data from an external device to an implantable component of a partially or fully implantable medical device. The separated power and data transfer techniques use a single external coil and a single implantable coil. The external coil is part of an external resonant circuit, while the implantable coil is part of an implantable resonant circuit. The external coil is configured to transcutaneously transfer power and data to the implantable coil using separate (different) power and data time slots. At least one of the external or internal resonant circuit is substantially more damped during the data time slot than during the power time slot.

A method of reducing a power consumption of a wireless device according to one embodiment includes performing, by the wireless device, a calibration of wireless communication circuitry of the wireless device in response to establishing a wireless communication connection with a wireless access point, determining, by the wireless device, a number of disconnections between the wireless device and the wireless access point over a predefined period of time, and increasing, by the wireless device, a sleep interval of the wireless communication circuitry of the wireless device in response to determining the number of disconnections between the wireless device and the wireless access point over the predefined period of time is less than a threshold number of disconnections.

A method for estimating the state of health of an exchangeable rechargeable battery. The method includes: i. determining a remaining capacity of the battery during a charging operation, in such a manner, that a first charging value is ascertained by measuring an open-circuit voltage, as long as no charging current or only a minimal charging current is flowing; at least one further charging value is ascertained by measuring the charging current in specific time intervals, until the charging operation is completed; and a sum of the ascertained charging values is calculated; ii. determining a remaining performance of the battery during the charging operation in such a manner, that after a predefined battery voltage is reached, the charging current is briefly changed, and the respective battery voltage is measured; and an impedance of the battery is calculated from the quotient of the difference of the measured charging currents and battery voltages.

A charging system for charging a vaporizer device is described. The charger may be adapted to control the output voltage to the vaporizer device, thus improving charging efficiency and reducing waste heat generation. Related systems, methods, and articles of manufacture are also described.

The present application describes systems and methods for authenticating rechargeable batteries in a rechargeable battery cabinet. The rechargeable battery cabinet may be a part of a large, scalable, distributed network of rechargeable battery cabinets, in which rechargeable battery cabinets may be removed or added based on consumer demand for fresh batteries. The system and methods may track the rechargeable batteries and where they are located in the rechargeable battery cabinets by first assigning a dynamic identification number, such that a rechargeable battery compartment does not need a static identifier. The system and method may allow for real-time reading of the status of rechargeable battery cabinets and rechargeable batteries in the system. Each rechargeable battery may have a static identifier to uniquely identify the rechargeable battery. This system and method allows for efficient scaling and identification of rechargeable battery within the system.

A power supply unit (PSU) configured to provide electrical power to an electronic device. The PSU may include a PSU control circuit configured to, via a power meter, detect that electrical power conveyed to the electronic device is above a timer starting threshold. In a first charging mode with a first predetermined charging duration, the PSU control circuit may control the PSU to convey electrical power to the electronic device with a first power ceiling. Subsequently to the first predetermined charging duration elapsing, in a second charging mode with a second predetermined charging duration, the PSU control circuit may control the PSU to convey electrical power to the electronic device with a second power ceiling that is lower than the first power ceiling. Subsequently to the second predetermined charging duration elapsing, the PSU control circuit may control the PSU to return to the first charging mode.

An electronic device is disclosed. The electronic device discloses a plurality of wireless charging antennas, a plurality of shielding partition layers, at least some of the plurality of shielding partition layers disposed between the plurality of wireless charging antennas, a plurality of external device-receiving grooves formed through spaces defined between pairs of the shielding partition layers, and a processor electrically coupled to the plurality of wireless charging antennas. The processor is configured to: determine whether at least one external device is inserted into at least one of the plurality of external device-receiving grooves, and when the at least one external device is inserted into the at least one of the plurality of external device-receiving grooves, wirelessly transmit power through at least one wireless charging antenna corresponding to the at least one of the plurality of external device-receiving grooves into which the at least one external device is inserted.

A battery in a mobile phone cover may be selectively charged according to a user-selectable parameter. When charged, the battery in the mobile phone cover may be used to charge a battery in a mobile phone.

A method and a device for making available electric charge in order to charge an electronic card including a near-field communication module by way of a terminal. The terminal has what is known as a reader mode in which it is able to supply power to the card in near-field mode and receive data from the card. The method includes the following steps, on the terminal, set to reader mode, so as to generate an electromagnetic field able to charge such an electronic card: initializing the communication between the terminal and the card; receiving a message from the card, the message containing at least one datum telling the terminal that it should maintain the electric charge; and maintaining the electric charge while remaining in reader mode.
