Patent NL-8702749-A (NL)
IPC: H04L7/06
Filed: 1987-11-18
Abstract: In a two-way remote control system a plurality of apparatus, including the hand-held unit, does not only comprise a transmitter but also a receiver. The receiver, inter alia, in the hand held unit is battery-fed. Since the receiver must be continuously in the operative state, this battery is exhausted very rapidly. To improve this, transmitters which deliver messages of a particular type have been selected in this system. In fact, each message comprises a series of pulses and the beginning of each message is marked by a wake-up pulse. At least the receiver which is battery-fed is provided with a wake-up pulse detection circuit controlling a switching circuit which switches the receiver from a rest state to the operative state after it has received of a wake-up pulse and which switches the receiver back to the rest state, in which state it consumes very little energy, if no wake-up pulse has been received for a certain period.
Patent NL-8703043-A (NL)
IPC: H05B6/06
Filed: 1987-12-16
Abstract: In an inductive heating apparatus two or more inductors (2, 3) can be connected to a single high-frequency generator (1). With such a heating apparatus, for example, the two supports (9, 10) having getter in a cathode ray tube can be heated simultaneously. In order to have the heating of each support (9, 10) proceed properly, the heating operations of the individual supports (9, 10) should be effected independently. Independent interruption of the electromagnetic power transfer from the inductors (2, 3) to the supports (9, 10) is preferably effected by axially moving away from the workpiece (4) a coil core (6, 8) inside the associated induction coil (5, 7). This preferred embodiment of the invention is advantageous in that in the case of low-ohmic inductors no large currents and in the case of high-ohmic inductors no large voltages need to be switched. In addition, the induction coils (5, 7), in the case of low-ohmic inductors (2, 3) often being formed by an internally cooled tubular conductor, can then be rigidly arranged.

Title: Subscriber equipment for wireless digital telephony - has control and MODEM processors directly coupled in assembly containing CODEC and universal transmitter receiver
IPC: H04M1/72502
Filed: 1990-12-18
Abstract: A base-band processor provides control of conversion of PCM signals at one bit rate to other bit rates. It converts received digital signals to voice signals and vice versa. It also provides echo cancellation where it uses dynamic memory to store received signals. PROM's store the echo cancellation program information as well as that for utilisation of the processor as a control processor. As a control processor it signals to the frequency synthesiser the frequency of operation for communication to the base station. The processor is directly coupled to a modem processor which is able to access the base band processor memory. This processor sends its signal at a predetermined sampling rate which are converted to analogue signals. The analogue signals are subjected to a cancellation process to reduce distortion. These signals are converted to an IF for addition to the synthesiser frequency to result in an HF signal for transmission.
