Title: Dual mode cellular/cordless telephone disabling cordless part when outside cordless coverage area
Inventor: DALSGAARD LARS
IPC: H04W48/18
Filed: 1997-02-05
Abstract: A dual or multi mode telephone capable of operating in a cellular and a cordless network (e.g. GSM/DECT) continuously monitors system information messages from the cellular network to maintain an idle mode connection. The phone periodically searches for a cordless network to monitor. When the telephone enters a new cellular network cell it stores the cell identification and compares it with cell IDs having cordless network coverage. If the comparison indicates that there is no cordless network coverage in the current cellular cell, then the cordless part of the phone is disabled. Thus energy is not wasted by searching for a cordless network when the phone is outside a cordless coverage area. Also disclosed is a dual mode telephone in which the cordless part is disabled when the phone is connected to an accessory part such as a car kit.

Title: Cell size adjustment in a cellular communication system
Inventor: KANAI TOSHIHITO
IPC: H04J13/00
Filed: 1997-03-11
Abstract: To reduce the traffic load in a cell of a cellular communication system, the cell size is reduced thus transferring traffic to adjacent cells. The quality (bit error rate or frame error rate) of a communication channel is monitored, with a deterioration in quality indicating traffic overload. Cell size is reduced by reducing the power of a pilot signal transmitted from the cell's base station or by changing the hand-off parameters (which may be set in the mobile). Adjacent cells increase in size in the same manner so that no gap in coverage is produced. A base station control apparatus for a CDMA system is described in which the uplink and downlink signal quality is monitored (the downlink quality being supplied by the mobile station). Soft hand-off is also described in which the soft hand-off area, where the mobile is communicable with both base stations, is shifted, reduced or expanded when cell size adjustment occurs.

Abstract: A clutch control system comprises a control unit 13a which receives signals from various sensors, eg throttle position sensor 15, shift lever sensors 19a, 19b, tachometer sensor 17 and gas pedal sensor 31. These incoming signals are evaluated, in the control unit 13a, by a control program which calculates and determines the outgoing values based on a comparison and/or functions and/or mapping. Outgoing signals are relayed to an electric motor 12 which controls actuator 13b via gearing. The actuator 13b is connected to a hydraulic master cylinder 11 which operates the clutch 3 via master cylinder 10. When a different torque level is required, for example when a vehicle is heavily loaded and at rest on an incline, the clutch 3 is controlled so as to provide a higher torque than normal so that the vehicle is accelerated from rest. Alternatively, depending on the circumstances, the clutch 3 may be controlled to deliver a reduced torque and acceleration. The system/method may be used with a manual or an automatic transmission.
