Title: Sewing machine control - has controlled solenoid drive circuit working according to function time and needle setting
Inventor: TSUKAHARA HISAAKI
IPC: D05B29/06
Filed: 1992-01-23
Abstract: Control unit for a sewing machine has a solenoid drive circuit connected to its output. Control depends on according to the functions of thread trimming, thread clearing and lifting the presser foot. Control sets the operating time of each solenoid at the drive circuit. Function switch units for the solenoid function pref. match the output function of the solenoid drive circuit for the sewing machine function and another function. Solenoid drive circuit has a further solenoid to control thread release, and the control to operate the solenoid control circuit also determines the time to operate the further solenoid coil. Time span for generating solenoid drive output signals is controlled according to the needle position, using the lower position in the case of an automatic double backstitch thread trimming machine, and the upper needle position in the case of an automatic chainstitch thread trimmer. Microcomputer controls the sewing machine, with the solenoid drive circuit connected to an output port, together with switching to set the solenoid function at the circuit. ADVANTAGE - Control system is cheap and operates the thread trimming at the most suitable time for each type of thread trimmer, with different trimming mechanisms, without further working. System has functions with a relatively small number of output signals and setting switches.

Title: Electronic anti-theft arrangement for motor vehicles and method for preventing thefts
Inventor: BAUER JUERGEN DIPL ING
IPC: B60R25/20
Filed: 1993-03-05
Abstract: Arrangements for preventing thefts usually have disablers of components necessary for locomotion and receivers for a deactivation code or some other owner-specific reference variable. A switching element for initiating authorised use is arranged at the output of the receiver. This switching element is a weak point in all the previously known arrangements for preventing thefts and is a target for attack from the potential thief. The new arrangement forces the thief to give up his intended theft and to abandon the vehicle by bringing about real technical defects which prevent it from being used. The vehicle does not have a deactivation receiver. A vessel with an electronic circuit is arranged in a protected and inaccessible area of the vehicle, which circuit is activated automatically by locking the vehicle in the usual way. The attempt at theft triggers a sequence of preprogrammed faults for the running time of a short-period timer circuit, the result of the said faults being that the vehicle cannot be moved. The faults are stored in a D flip-flops. Deactivation is brought about by successive brief activations of original switches which have to be activated in a sequence, specified by the owner of the vehicle, before or just after the ignition lock is switched on. Via relay couplers the switches flip a fail safe electronic circuit system which consists of main memories and auxiliary memories and at the end of the... Original abstract incomplete. <IMAGE>
