  • Patent number: 6697646
    Abstract: A transceiver comprises a vibration motor for vibrating the transceiver itself in order to notice a call to a user. The vibration motor is driven when a receiving unit issues a received signal in a vibration mode. The vibration motor is prohibited, for a specific time, from being driven when the user operates a specific action such as pushing a transmission button. The transceiver can make a recipient pay attention by vibration without disturbing the user attending, for example, a meeting. Since the vibration motor is not driven while a transmission or reception is repeated within the specific time, users can talk smoothly with the transceiver.

  • Patent number: 6694146
    Abstract: Energy expenditure is reduced in a wireless subscriber station operating in a Cellular Digital Packet Data (CDPD) system by deleting the operation of decoding the Forward Error Correction (FEC) blocks. The decoding of the FEC blocks can be deleted by virtue of using opening and closing Temporary Equipment Identifier (TEI) messages having a minimum hamming distance from all the other TEI messages. Base Error Rate (BER) is measured to determine when the necessity of decoding an FEC block exists. By limiting this operation, battery life for wireless subscriber stations is prolonged.

  • Patent number: 6690662
    Abstract: An approach to improving TDMA system operation is disclosed wherein in-band translator components are located in the center of remote cells which would normally contain a base transceiver system (BTS). The in-band. translators employ wireless in-band signaling for downlink transmission of commands from an operation and maintenance center (OMC) and uplink transmission of status-indicating and alarm signal data. The remotely located repeaters of the present invention have frequency shift key detection and demodulation capability incorporated in the downlink path, while also incorporating FSK modulation capability into the uplink path. This allows the repeater to extract commands from the serving BTS downlink signal and act on them. It also allows for the repeater to transmit status-indicating signals and alarms to the OMC via the uplink path to the serving BTS.

  • Patent number: 6678534
    Abstract: When any application can be operated, a control section first indexes a table for defining validness or invalidness of an operating key corresponding to an application in a memory. Then, if the control section detects that any key is operated, the control section starts to turn ON a back light. Thereafter, the control section detects that any key is manipulated again before a lighting time set by a timer elapses, and it is decided whether the operation section is a valid key. If the valid key is operated, a first back light for illuminating the most neighboring part of the valid key and a second back light for illuminating a display section are continuously turned ON until the lighting time set by the timer of the control section elapses. However, if the lighting time set by the timer of the control section elapses, the back light is turned OFF.

  • Patent number: 6631273
    Abstract: Modern portable communications units, and in particular cellular telephones, can contain several frequency bands for receiving and several frequency bands for transmitting signals. Typically these units contain a baseband unit and a frequency synthesizer unit, which may be embodied as VLSI integrated circuits. The baseband unit commonly contains the user interfaces and control signals for controlling other portions of the circuitry. The second unit is sometimes called a frequency synthesizer unit. The second unit is dedicated to producing frequencies that are used by the communications system to create RF signals for broadcast and also to take RF signals and extract the modulated signal from them for decoding. As personal communications units have begun using an increasing number of bands it is often necessary to configure different filters to receive or broadcast the different bands. Typically, the baseband Integrated Circuit or separate circuitry does this filter configuration management.
