Title: Driver for high voltage half-bridge circuits
Inventor: WEGENER ARMIN
IPC: H03K17/06
Filed: 1990-05-02
Abstract: A driver circuit for a high-voltage switching power transistor has a first stage connected to the power transistor control terminal (CON) for turning the power transistor on and off, and a second stage connected to the power transistor control terminal (CON) acting as a current sink for capacitive current due to the transistor capacitances. The second stage is arranged to turn on when the power transistor control terminal voltage falls below a turn-on value and to be turned off when that voltage rises above a turn-on value. A driver circuit for a high-­voltage half-bridge switching power circuit, having two such power transistors (T1, T2) connected in series, has similar upper and lower driver circuits (DU, DL) and a level shifting circuit (LS) for providing control pulses to the upper driving circuit.

Abstract: A sausage casing comprises a cylindrical container (1) formed from a laminated sheet of material having a central nylon film (2) and outer films (3) of polyethylene. The longer sides of the laminate are brought into abutment (at 1') and sealed by a tape 4 which is adhered over the area (8) leaving unadhered side portions (7). The tape (4) may comprise a laminate of a nylon film (5) and a polyethylene film (6) which is heat sealed to the laminate (1) 
     To open the casing rapidly so as to expose the contents for further processing, the side portions (7) are lifted up and grasped with the fingers as shown in Figure 2, and the tape pulled away from the casing completely. This arrangement avoids the need to use a cutter or the like which can damage or mark the casing contents.

Abstract: A processing method capable of effecting any frequency conversion such as expansion, compression and inversion, of the shift frequency of a Doppler shift signal. The shift frequency components of the measured Doppler shift signal are multiplied by an arbitral number in order to remove the aliasing and to heighten the precision of detecting a low-speed object. A phase difference generated at a time interval longer than a very short time interval at a given moment is substituted for a phase difference of the very short time interval. This frequency conversion can be arbitrarily adapted to a continuous-wave Doppler method and a pulse Doppler method.

Abstract: A method for avoiding interference between two messages in a mobile telephone system which operates on the time divided multiple access system (TDMA). The first message (RA) constitutes a request for the establishment of a connection from a mobile station (M2) to a base station (B1) in the system, and the second message (HA) constitutes a request for handover access from a second mobile station (M1) to another base station (B2) in the system. These two messages may possibly be transmitted on one and the same carrier frequency and their respective radio channels (RACCH and FACCH) may be confused with one another, causing the messages to be misinterpreted by a base station (B1). According to the method, a given data field of each message is coded so that the data field (HNR) of the one message will not assume the same code combination as the data field (CA) of the other message. The method can also be applied such that the two messages (HA1, HA2) concerning handover access or two messages concerning random access request can be distinguished one from the other.
