Patent CA-2329532-A1 (CA)
Inventor: SCHULZ EGON
IPC: H04B7/005
Filed: 1999-04-13
Abstract: The invention relates to a method for operating a wireless telecommunications device which comprises at least one base station and at least one mobile part (PT). The mobile part (PT) has a control loop (RK) for independently controlling the transmitter power according to special information (A-/X-CRC) which is transmitted on the side of the base station and/or for controlling the receiving field strength (FSW) of the base station transmitted signal. A protocol-oriented, standardized information and message exchange is carried out between the base station and the mobile part (PT) over a common air interface. According to the invention, the at least one base station transmits administration procedures (RFP status signal) over the common air interface. Said administration procedures are retrieved by the mobile part (PT) which is located in the reception area. A piece of additional status information contained in the administration procedures is recognized by a microcontroller (MIC) by reverting to a bit which is free up to now. From this, said microcontroller derives a control signal (AS). The transmitter power control (RK) can be activated and deactivated on the side of the base station with the assistance of said control signal (AS).

Patent CA-2330927-A1 (CA)
Inventor: MCEWAN THOMAS E
IPC: G11C27/02
Filed: 1999-05-13
Abstract: A wideband sample-hold circuit (10) is formed with a single diode (D) in a minimum component configuration. A gate circuit comprised of a first capacitor (Cg) and an impedance element (Z) forms a gate pulse, stores the sampled signal charge on the first capacitor (Cg), and transfers the charge to a second capacitor (Ch) via the impedance element (Z). The impedance element (Z) also defines the gate pulse width, in combination with the first capacitor (Cg). In a preferred mode, the first capacitor (Cg) is responsive to individual gate pulses while the larger second capacitor (Ch) integrates charge packets from the first capacitor (Cg) due to multiple gate pulses to provide an integrated baseband output (20). In radar rangefinder applications, the baseband output (20) is an equivalent time replica of the RF input (18). The sample-hold circuit (10) has other applications in radar motion sensing and time domain reflectometry.

Filed: 1999-06-23
Abstract: Left and right stereo audio information is reproduced from a compatible quadrature amplitude modulation (C-QUAM) broadcast using a simplified approximation to true C-QUAM decoding. A synchronous detection approximation is used which avoids generating an envelope signal or calculating a cosine correction factor as in true C-QUAM  decoding. The method requires less intensive computation power thereby allowing a digital signal processor to perform other functions at the same time. The method produces no perceivable distortion or artifacts when reproducing normal broadcast material.
