摘要: The wireless power transmission is a system for providing wireless charging and/or primary power to electronic/electrical devices via microwave energy. The microwave energy is focused to a location by a power transmitter having one or more adaptively-phased microwave array emitters. Rectennas within the device to be charged receive and rectify the microwave energy and use it for battery charging and/or for primary power.

摘要: A transmitter assembly is useful in optimizing the delivery of wireless power to a plurality of receivers. Each receiver measures its own battery need for power and transmits that measurement as a request to the transmitter. The transmitter is configured to normalize and compare battery need requests. The transmitter then allocates pulses of wireless power among the requesting receivers according to their battery need.

摘要: A backscatter radio system having a transceiver module and a transponder. The transceiver module is configured to generate and transmit a radio frequency pulse signal with Pulse Position Modulation (PPM). The generated radio frequency pulse signal includes a power and information transferring pulse and a time reference pulse within a dual symbol duration comprising a first and a second symbol periods. The power and information transferring pulse enables a power injection to a rectifier circuit in the transponder and the time reference pulse enables an excitation of a resonance signal in a resonance circuit in the transponder. A response radio frequency pulse signal with PPM is generated using the resonance signal generated in the resonance circuit with a time offset such that the first and second symbol periods are separated in the time domain.

摘要: Provided is a system comprising a base station and a terminal apparatus that communicate with each other by selectively using plural radio resources, which is capable of supplying a power to the terminal apparatus using a communication-unused radio resource between the base station and the terminal apparatus. The base station generates a transmission signal including a dummy signal for wireless power transfer using a communication-unused radio resource that is not used for communication among plural radio resources, and transmits the generated transmission signal to the terminal apparatus. The terminal apparatus receives the transmission signal including the dummy signal transmitted from the base station, and outputs an electric power of the reception signal as a reception power. A battery may be charged using the reception power.

摘要: A wireless power transfer system is provided for mobile charging of one or more listening devices. A case configured for attachment to a mobile electronic device having a wireless power transfer antenna includes a first plate and a second plate expandably connected to the first plate, such that when expanded, the first plate and a second plate define a hollow for each of the listening devices. Each hollow is shaped and located to hold a listening device in a coupling position with the wireless power transfer antenna of the mobile electronic device when the case is mounted to the mobile electronic device. An attachment may be used to mount the case to the mobile electronic device.

摘要: A device includes a signaling means and a motion sensor, and logic for activating or controlling the signaling means in response to a sensed motion according to an embedded logic. The device may be used as a toy, and may be shaped like a play ball or as a handheld unit. It may be powered from a battery, either chargeable from an AC power source directly or contactless by using induction or by converting electrical energy from harvested kinetic energy. The embedded logic may activate or control the signaling means, predictably or randomly, in response to sensed acceleration magnitude or direction, such as sensing the crossing of a preset threshold or sensing the peak value. The visual means may be a numeric display for displaying a value associated with the count of the number of times the threshold has been exceeded or the peak magnitude of the acceleration sensed.
