Title: Digital filter with rounding error correction - is affected by binary random pulse train replacing rounding bit so that limit cycles cannot develop
Inventor: BUETTNER MANFRED DIPL ING
IPC: H03H17/04
Filed: 1975-08-20
Abstract: A rounding bit is replaced by a random number in at least one path of the feed-back loop of a recursive system in the not yet shortened sum of products. This number is later used for decision as to whether rounding should take place upwards or downwards. It is important for the efficiency of suppression of limit cycles that the rounding error should not become periodic. To prevent this the rounding error is made to depend on the random pulse train and is, therefore, stochastic.

Title: Safety indicator for car dashboard - with relay operated warning light and fused monitoring circuit for permanent indication
Inventor: WEILAND FERNAND J ING GRAD
IPC: B60T17/22
Filed: 1975-10-15
Abstract: The safety monitoring circuit has a set of switches (2) operated by brake failure circuits, fluid level indicators etc. to close when some system fails or reaches danger level. The switches are coupled to the live side of the ignition switch (1) and pass a current through a limiting resistor (3) into a fuse link (4). The fuse link burns out and the rising potential at the resistor allows the current to be shunted by a diode (9) through a control coil (8) of a reed relay (5). The relay operates the warning light on the dashboard. The light (6) cannot be cancelled by switching off the ignition, for as the ignition is switched on again, the light is relit. Inspection of the fuse links identifies the failure cause. The whole circuit can be miniturised to fit behind any dashboard.
