    Abstract: A rectifier circuit for increasing an output voltage is realized. Provided is a rectifier circuit including: a first line including a first series circuit in which two or more switching elements are connected in series; a second line including a second series circuit in which three or more switching elements are connected in series, the second series circuit being connected in parallel with the first series circuit; one or more first antenna elements connected between the switching elements of the first series circuit; and one or more second antenna elements connected between the switching elements of the second series circuit, in which an output is extracted from a parallel connection point between the first series circuit and the second series circuit.

    Abstract: An electronic device comprises a photovoltaic unit, an energy storage unit, a voltage detector, a load switch and an application load. The device is configured to harvest and store energy from ambient illumination, and to optimise power delivery to the application load from at least one of the harvested energy and the stored energy. The photovoltaic unit, the energy storage unit, the voltage detector and an input of the load switch are connected to a common point. The photovoltaic unit harvests energy from the ambient illumination. An output of the load switch is coupled to the application load. The voltage detector measures a voltage at the common point and turns on the load switch when the measured voltage has increased to a level that is greater than or equal to a first voltage, in order to provide optimised power delivery to the application load from at least one of the energy storage unit and photovoltaic unit. The voltage detector turns off the load switch when the measured voltage has decreased to a level that is not greater than a second voltage, in order that the photovoltaic unit stores energy in the energy storage unit, wherein the first voltage is greater than the second voltage.

    Abstract: Systems and methods for wirelessly locating users in a venue via their respective portable device are taught. Wireless transmitter devices positioned at different locations in the venue are used. Each transmitter device transmits an identifier to the portable device. Some transmitter devices can be part of a wireless-power transmitter that is additionally capable of charging portable devices. A software on the portable device is able to determine the closest transmitter device and, by finding its identifier in a database, its location within the venue. Once the portable device is aware of its location, it can be used to control nearby external devices. Through information stored in the database, the software is also able to display the location of other users and usage statistics of the venue. Different methods of ensuring that portable devices are paired with the closest transmitter device are taught.

    Abstract: An integrated circuit is described. This integrated circuit may include wireless-charger transmitter. The wireless-charger transmitter includes a driver circuit. Moreover, the wireless-charger transmitter selectively filters out an interference signal in a band of frequencies corresponding to AM radio. Note that the selective filtering may be performed by at least a filtering circuit. For example, the filtering circuit may include a low-pass filter. Moreover, the selective filtering using the filtering circuit may be based at least in part on a switching frequency of the wireless-charger transmitter. Furthermore, a filtering frequency associated with the filtering circuit (such as a 3 dB cutoff frequency of a low-pass filter) may be adjusted by selectively electrically coupling a set of capacitors in parallel with the filtering circuit.
