  • Publication number: 20140266641
    Abstract: A power spectral density (PSD) shape may be modified based upon the transmitter power setting of a transmitter. The power associated with notched frequencies and adjacent frequencies may be adjusted responsive to a change in transmitter power setting. As a result of adjusting the power for the notched frequencies and adjacent frequencies when operating at the different transmitter power setting, the performance of the transmission system is improved. The PSD shape may be considered dynamic, being modified responsive to a change in transmitter power setting by adjusting power associated with notches in the PSD shape based on the transmitter power setting and PSD constraint.

  • Patent number: 8587413
    Abstract: An information access system includes a reader/writer device and an information storage device. In the information storage device, a receiver unit senses a carrier of an RF signal at a first frequency for detection, in a first time period occurring at time intervals, and receives an information request signal in response to detection of a carrier of an RF signal at the first frequency, and senses a carrier of an RF signal at a second frequency in response to reception of the information request signal. In the storage device, a control causes the receiver unit to sense a carrier of an RF signal at the first frequency for detection, in a second time period after a sleep time period which is shorter than the time interval, in response to non-detection by the receiver unit of a carrier of an RF signal at the first frequency in the first time period.

  • Patent number: 8570186
    Abstract: A wireless sensor reader is provided to interface with a wireless sensor. The wireless sensor reader transmits an excitation pulse to cause the wireless sensor to generate a ring signal. The wireless sensor reader receives and amplifies the ring signal and sends the signal to a phase-locked loop. A voltage-controlled oscillator in the phase-locked loop locks onto the ring signal frequency and generates a count signal at a frequency related to the ring signal frequency. The voltage-controlled oscillator is placed into a hold mode where the control voltage is maintained constant to allow the count signal frequency to be determined. The reader uses an ambient reading or other information to select a subset of the possible ring signal frequencies, and tunes or adjusts its circuits and algorithms to focus on that subset.

    Abstract: The invention relates to a multimedia device comprising a remote control system for wirelessly controlling a multimedia appliance. In order to establish a connection between a remote control system and a multimedia appliance, the remote control system must identify itself to the multimedia appliance, by means of a hardware device, especially a SIM card. The individual user must also identify him/herself to the multimedia appliance, by means of a hardware device for detecting biometric data. The respective identification data is encoded by means of asymmetrical cryptography. During the initialization process between said two appliances, data encoded for the identification of the remote control system and each person is transmitted to the multimedia appliance and stored therein in an encoded manner.
