Abstract:
Embodiments include an implant and a method of operating the implant. The implant includes a receiver that receives first ultrasound signals emitted by an external transmitting unit of a further apparatus. The receiver includes a piezoelement, which is excited by the first ultrasound signals at a first resonance frequency (f1) and therefrom converts the mechanical energy transferred with the first ultrasound signals into electrical energy. In embodiments of the invention, the piezoelement is additionally excited at a second resonance frequency (f2), which differs from the first resonance frequency (f1), and at the second resonance frequency (f2) operates as a transmitter to transmit second ultrasound signals.

According to one embodiment, a remote control device for a toilet device includes an operation button and a power generator. The operation button is capable of a push operation and is configured to operate an equipment in response to the push operation. The power generator is configured to generate a power by being pressed in response to the push operation. A direction of the pressing is parallel to a wall surface on which the remote control device is placed.

Abstract:
In order to know a communication state similar to an actual usage state of a user over a wide area, provided is an information processing apparatus that sends and receives information to and from a communication terminal via a network. The information processing apparatus includes a log information acquiring section that acquires, from the communication terminal, one or more pieces of log information in which position information identifying each of one or more positions and information relating to a communication environment of the communication terminal at each of the one or more positions are associated with each other; and a statistical information generating section that generates statistical information relating to the communication environment at a position, based on the one or more pieces of log information.
Abstract:
Receivers, apparatuses, and methods associated with packet classification based power saving receiver are described. In one embodiment, a method includes detecting an incoming frame at a receive unit. Expected power savings are calculated based, at least in part, on a switching time and frame duration of the incoming frame. The method further includes determining to enter an ignore frame state rather than a receive frame state based, at least in part, on the expected power savings. In the receive frame state the incoming frame is received by the receive unit. In the ignore frame state the incoming frame is either not received or not decoded. The method also includes selectively controlling the receive unit to enter the ignore frame state from the receive frame state. The receive unit is returned to the receive frame state in time to perform end of frame processing on the incoming frame.
Abstract:
A wearable device is disclosed that, while being worn by a user, may allow a user to authenticate to a second device such as a smartphone without having to enter an unlock code such as a personal identification number. The wearable device may detect when the user removes it. Removal of the wearable device may cause it to be disabled and prevent it from being used to authenticate a subsequent user to the second device until it is re-enabled.
Abstract:
According to one aspect, an electronic device adapted to be controlled by an audio accessory. The electronic device includes at least one resonator. Each resonator is tuned to respond to a particular frequency that corresponds to a particular message generated by the audio accessory. When the particular message is received, the corresponding resonator resonates to generate an output signal that controls the electronic device.
Abstract:
The invention relates to a method and apparatus for wireless remote control. A transmitter (1) with no batteries receives its operating power from a generator (3) which produces electrical energy inductively upon turning or pressing an operating element (4) manually. The same operating element can also be used for determining the direction and degree of control.
Abstract:
A piezoelectric device is connected in parallel with a diode, and outputs a power generation voltage when depressed. When the power generation voltage exceeds a first threshold voltage, a load switch control circuit makes a load switch be conductive, and when the generated voltage becomes lower than a second threshold voltage, the load switch is cut off. Further, when depression is released, the piezoelectric device is discharged by the diode such that the amount of charge remaining in the piezoelectric device becomes zero.
