Title: Method for synchronously sorting digital value quantities
Inventor: HANEKE EKKEHARD DIPL ING
IPC: B07C5/10
Filed: 1985-05-03
Abstract: In this method, a current image of an object is obtained by means of an opto-electronic sensor and compared with a predetermined reference image. The respective signals for a subsequent sorting process are derived from the comparison. To reduce the error rate and thus to increase the quality of correlation, the current binary word is successively compared with reference words from memory chips (9, 10) via a comparator (5, 6), the smaller current word written in place of the corresponding reference word when it drops below the reference word, and the remaining reference words shifted on by one address via a buffer memory (11, 12), the last reference word dropping out due to the current word shifted in. Instead of minimum sorting, this method can be used for carrying out maximum sorting when the reference word is exceeded. <IMAGE>

Patent DE-3616865-A1 (DE)
Title: Digital magnetometer
Inventor: DRUNG DIETMAR DIPL ING
IPC: H03M1/00
Filed: 1986-05-20
Abstract: Interferometers having two Josephson contacts are used for high-sensitivity measurement of magnetic fields. These interferometers have an analogue negative feedback circuit between the interferometer output and a negative feedback coil. The invention uses a partially digital negative feedback circuit in order to ensure that the measurement data are transmitted without interference. The invention comprises an interferometer having two Josephson contacts, one clock generator, one binary up/down counter and a digital to analogue converter. In contrast to conventional concepts, the Josephson contacts must have hysteresis in the current/voltage characteristics. The clock generator impresses a pulsed gate current into the interferometer so that the latter switches into the voltage state with a probability which is dependent on the magnetic field to be measured. The sequence of voltage pulses produced to the output of the interferometer controls the up/down counter in such a manner that it counts upwards or downwards respectively by one digit depending on whether one voltage pulse or no voltage pulse, respectively, occurs during a gate-current pulse. The digital to analogue converter transforms the counter reading into a current which is supplied into the negative feedback coil of the interferometer. This negative feedback current and thus the counter reading are proportional to the magnetic field to be measured.
