  • Wireless communication circuit, wireless communication terminal and method, recording medium, and program
    Patent number: 7031662
    Abstract: In a communication terminal that is capable of carrying out communications based on a plurality of communication standards, for example, a cellular phone, information representing a reception carrier frequency of a wireless channel being received by a cellular-phone functional block is output from a CPU to a contactless-IC-card-reader/writer functional block. In the contactless-IC-card-reader/writer functional block, a controller controls a switching circuit to switch a transmission carrier frequency being used so that harmonic components of an electromagnetic wave radiated from a coil antenna will not work as an electromagnetic-interference wave that affects reception sensitivity of the cellular-phone functional block.

  • Portable wireless communications unit and lighting control method thereof
    Patent number: 5970419
    Abstract: A backlight for a liquid crystal display in TMDA type portable telephones is driven by PWM. A register for holding the PWM-drive pulse width setting values and a decoder for decoding counted values in a base counter for counting the basic timing of three slots for receive, idle and transmit. A lighting control circuit Scb is provided to cut off the supply of power to the backlight incandescent lamp from the secondary battery during the transmit time slot. The power cutoff period by means of the Scb signal may be extended beyond the transmit time slot depending on the voltage detected at the secondary battery terminal by means of a voltage sensor circuit. Consequently additional voltage drops in a battery can be avoided during transmission in a TMDA type portable telephone by switching off a light such as a backlight for a liquid crystal display.
