摘要: Object detection in wireless power systems and related system, methods, and devices are disclosed. A controller for a wireless power transmitter includes a measurement voltage potential input terminal and a processing core. The processing core is to determine an average of peak to peak amplitude differences present in sampled measurement voltage potentials for each of the plurality of transmit coils, determine a lowest average of the peak to peak amplitude differences, and select a transmit coil corresponding to the lowest average of the peak to peak amplitude differences to transmit wireless power to a receive coil of a wireless power receiver. A wireless power system includes a tank circuit selectively including any one of a plurality of transmit coils.

摘要: The present invention relates to an electrical resonator (10), and an array (30) comprising a plurality of the electrical resonators (10). The electrical resonator (10) comprises an inductor coil comprising at least one turn. The at least one turn comprises an outer turn defining an outer coil perimeter (14). The electrical resonator comprises at least one capacitor connected to the inductor coil. The outer coil perimeter (14) comprises four major edges (141). Each of the major edge (141) is substantially linear and arranged on a different edge of a quadrilateral. The outer coil perimeter (14) comprises four minor edges (142) connecting the major edges (141). The array (30) comprises a first plurality of the electrical resonators (10a) arranged in a first layer, and a second plurality of the electrical resonators (10b) arranged in a second layer on top of the first layer. The minor edge (142a) of each electrical resonator substantially abuts the minor edge (142b) of an adjacent electrical resonator in the same layer, and the first and second layer together define a quadrilateral array of the electrical resonators (30), with a centre of each inductor coil in the first layer coincident with the centre of a gap region between inductor coils in the second layer. A method of arranging a plurality of electrical resonators in an array is also disclosed.

摘要: A receiver unit of a wireless power transfer system is presented. The receiver unit includes a main receiver coil, a plurality of auxiliary receiver coils disposed about a central axis of the main receiver coil, and a receiver drive subunit. The receiver drive subunit includes a main converter operatively coupled to the main receiver coil and having a main output terminal. The receiver drive subunit may include a plurality of auxiliary converters operatively coupled to the plurality of auxiliary receiver coils. The plurality of auxiliary converters may be operatively coupled to each other to form an auxiliary output terminal coupled in series to the main output terminal to form a common output terminal. In some implementations, the receiver drive unit may be formed on a substrate of an integrated electronic component. The integrated electronic component may further include a communication subunit and a controller disposed.

摘要: A footwear system includes a sensorized insole, a wireless charging transmitter pod, and a wireless charging mat. The insole has an insole bulk having a foot-facing upper surface and a ground-facing lower surface. One or more sensors, one or more batteries, and a wireless charging receiver pod are embedded in the insole bulk. The transmitter pod receives energy and wirelessly transmits energy to the receiver pod. The transmitter pod is positionable against the foot-facing upper surface to wirelessly provide energy to the receiver pod through the insole bulk. The mat receives energy and wirelessly transmits energy to the receiver pod. The mat is positionable adjacent the ground-facing lower surface to wirelessly provide energy to the receiver pod through the first insole bulk. The system is configured to allow only one of the transmitter pod and the mat to provide energy to the receiver pod at a given time.
