Patent DE-3046078-A1 (DE)
Inventor: BACH ERIK
IPC: A63H19/24
Filed: 1980-12-06
Abstract: The regulating apparatus has a control knob (20) with a coupling hole (25) so that it can be pushed, in a manner such as to be axially displaceable but proof against rotation, onto a switching spindle of a toy transformer with a choice of voltage. The control knob (20), which is open on one side, has a flat floor surface (21) and two flat side walls (22), a flat end wall (23) and a semi-cylindrical end wall (24) which has an end surface (24a) higher than those (22a, 23a) of the other walls (22, 23). When the control knob (20) is brought to rest on a flat base provided with stop cams, the range of angle of rotation, when the control knob (20) is pushed on with its bottom surface (21) facing the base, is restricted by the striking of two adjacent corners of the control knob (20) against the stop cams. When the control knob (20) is pushed on in a reversed manner, the less high end surfaces (22a, 23a) permit unimpeded rotation. As a result, two different ranges of voltage regulation, e.g. 0 to 4.5 V and 0 to 12 V, can be unmistakeably defined by reversing the control knob. <IMAGE>

Title: Navigation referencing by means of a contour sensor with map comparison
Inventor: MUEHLENFELD EIKE PROF DR ING
IPC: G01C21/00
Filed: 1981-03-13
Abstract: The accuracy of a navigation system independent of ground stations or satellites is to be improved by precise and reliable position referencing. This makes it possible to reduce the demands on the compound navigation method to be referenced, and the costs. The position referencing described in the application is carried out by automatic detection of traffic routes and rivers overflown and automatic locating of these line structures by means of a microcomputer. Location and erection of the traffic routes are determined even against a highly structured background and with weak contrast by an essentially radial scanning of the terrain overflown or of an intermediate image. The comparison of detected contours with the data of a map carried on board and reduced to line structures provides a line image of possible actual positions. Using all earlier measurements and the current reference data, the position error which has occurred is determined by means of a recursive optimal filter, taking into consideration the compound drift. <IMAGE>
