The key must be inserted into a compartment (with a flap to protect against contamination) in order to activate the power circuit since the key closes the current circuit in the lock housing. ADVANTAGE - Combined electronic lock with burglar alarm.
Patent DE-4310867-A1 (DE)
Title: Radiant wall for wall cooling or heating in spaces
Inventor: HILBERS HEINRICH DIPL ING
IPC: E04C2/52
Filed: 1993-04-02
Abstract: The invention relates to an air-conditioning component which has the advantage of introducing cooling energy into the space, whether it be an office, conference room, business premises and the like, in a comfortable form. In doing so, the increase in air circulation is to be altered, but, in an interaction of the cooling-surface radiation from a directed surface and the cooling energy to be transported in the room supply air, the required temperature can be jointly maintained. The advantageous interaction leads to a considerable reduction in the cost of air-transporting equipment, and thus also large air-duct cross-sections. The method is suitable for retrospective use in existing buildings, since in this case vertical room partitions can be provided with radiant surfaces, can be easily installed in the building and can be connected to the energy carrier, without causing considerable disruption to the work of the people employed there.

Title: MOS semiconductor component
Inventor: STRACK HELMUT DR
IPC: H01L29/739
Filed: 1993-05-11
Abstract: The source regions (14) of the semiconductor component are arranged on the upper side of the gate electrode (4) and are there connected on their upper side with a source electrode (6). The base region (5) laterally adjoins the source region and, laterally to the gate electrode, adjoins the drain region. The minority charge carriers flowing from the semiconductor body to the cathode therefore flow directly to the source electrode (6) via the part of the base region (5) located next to the gate electrode. Turning on of the parasitic bipolar transistor and therefore the occurrence of "second breakdown" is thereby avoided. <IMAGE>

Title: Process for detecting misfires in an internal combustion engine
Inventor: HAFNER SIGRID DIPL ING
IPC: G01M15/11
Filed: 1993-10-02
Abstract: Process for detecting misfires in an internal combustion engine, the crankshaft of the internal combustion engine having assigned to it a sensor for determining the speed of rotation and at least one crankshaft segment being fixed for each cylinder. By means of the speed of rotation, the segment time (tSEG) is determined and the differences ( DELTA tSEG) are subsequently determined from two successive segment times (tSEGn, tSEGn-1). In a first phase, from the registered values for each operating point and each possible error, a multiplicity of process units is calculated, each of these process units being determined by means of a weighting vector and containing an item of information (I). These weighting vectors are stored in a memory unit of the internal combustion engine. In a second phase, during the operation of the internal combustion engine under operating conditions, sample vectors are calculated from the values now currently registered and are compared with learned individual weighting vectors of the process units. In this way, that process unit is selected which exhibits the smallest separation from the weighting vectors of the currently calculated sample vectors. Subsequently, the item of information from the process unit is output as a diagnostic result of the functioning of the internal combustion engine. <IMAGE>
