  • Patent number: 10014637
    Abstract: A device is equipped with an electrical connector in the form of a receptacle that is subject to liquid intrusion. The device detects the insertion of a mating connector and optionally detects the presence of liquid in the receptacle by applying a low power, pulsed sense signal to a terminal pin of the receptacle while the terminal pin is decoupled from a circuit part to which the terminal pin is normally coupled and concurrently sensing a voltage coupled from the terminal pin and comparing the voltage to at least a predetermined lower voltage bound and optionally a predetermined upper voltage bound and based on the results of those comparison deduces the presence of a mating connector or optionally the presence of liquid in the receptacle.

  • Publication number: 20140094229
    Abstract: An attitude detector installed in a cabinet detects the current attitude of the cabinet. Control circuitry suppresses radiated output power of a wireless transceiver in accordance with the current attitude of the cabinet, which is detected by the attitude detection unit. The attitude detection unit obtains two angles ? and ? based on x-axis, y-axis, and z-axis outputs of a three-axis acceleration sensor, for example. The control circuitry determines the necessity or lack thereof of the suppression of the radiated output power in accordance with a combination of the angle values.

  • Patent number: 7739745
    Abstract: An information-processing apparatus comprises an acquisition unit configured to acquire information about a communication-method type from a display device connected to the information-processing apparatus, a determination unit configured to determine whether or not the display device is adapted to receive data on digital contents by using a predetermined copyright-protection technology based on the communication-method-type information, a conversion unit configured to convert an image quality of the digital contents based on the determination result, and an output unit configured to transmit the converted digital contents to the display device.
