Patent DE-4326454-A1 (DE)
Title: Motor-driven zoom lens photographic camera
Inventor: KIRIGAYA TADAYUKI
IPC: G02B7/28
Filed: 1993-08-06
Abstract: A main CPU (35) in the camera body communicates with a lens CPU (61), and calculates a defocus amount on the basis of data from a macrometric CCD sensor unit (21). The main CPU drives an AF motor (39) using the rotational direction and pulse number of the motor as determined by the CPU. The motor communicates with the lens (51) through a drive mechanism (55). A focussing operation is actuated either on commencing, during or on stopping the changing of the focal length using a zoom ring. The focussing operation is actuated when a neutral position of the focal length changer is detected. An object magnification is determined using distance data and current focal length when ther focussing operation is completed.

Title: Control of torque transfer between IC engine and gearbox - Has fluid torque converter in parallel with friction clutch and adaptive control procedure to adjust clutch slip
Inventor: OTTO DIETER
IPC: F16H59/24
Filed: 1993-08-21
Abstract: The control of torque transmission to an automatic gearbox from an IC engine, involves a fluid torque converter and a parallel friction clutch between engine and gearbox, with sensors and central microcomputer unit, so that the friction forces in the clutch, and therefore transmitted torque, is controllable. The process used is adaptive control so that the slip is the minimum necessary and deviations from the ideal are eliminated by corrections. An iterative equation (similar to the over-relaxation equation in finite difference methods) links the clutch torque corrections with the new clutch torque value via a torque distribution factor. USE- For automatic gearbox systems.

Patent DE-4332753-A1 (DE)
Inventor: MESTER RUDOLF DIPL ING DR
IPC: G06T7/246
Filed: 1993-09-25
Abstract: A method which is used for optically detecting moving objects method comprises an image recording unit 1, a computing unit 2 with a memory 4, and a signal display 5. The computing unit compares an image recorded by the image recording unit with a reference image in relation to the measured variables: image signal variation, displacement and texture. For determining the comparison values the chronological mean value and the chronological variance are thus preferably used for describing the typical distribution of the measured variables in each case. If the comparison displays an atypical image signal variation and an atypical texture and an atypical displacement, a moving object is detected, a signal is emitted, and the actual image signal is stored as the new reference image signal and is used as the reference image signal for the next comparison. <IMAGE>

Title: Preventing acoustic feedback in the microphone circuit
Inventor: LOBEMEIER RUDOLF
IPC: H04R3/02
Filed: 1993-10-05
Abstract: This method deals with the suppression of the feedback whistle frequently occurring in microphone transmissions. This is done by limiting the amplitude of the microphone signal when a sine wave rising above the useful signal is detected. From this rise, a control voltage is formed which limits the gain at this point. This prevents feedback from arising.

Title: Clamping aid for fretsaw blades
Inventor: BROCKMANN PETER
IPC: B23D51/12
Filed: 1993-10-29
Abstract: The clamping of a fretsaw blade is simplified and facilitated by the clamping aid. The clamping aid can be mounted on any fretsaw. The fretsaw frame is pretensioned and arrested by means of the clamping aid. The clamping aid consists of any desired material. The clamping aid can be mounted at any location on the fretsaw frame.   The arresting of the pretensioned fretsaw frame is effected according to any desired principle with the aid of the bow of the clamping aid.   The clamping aid facilitates the clamping of a fretsaw blade. Furthermore, it prevents material fatigue in the fretsaw frame, since the frame is handled with constant pretension by the clamping aid. Figures 1 to 3 show the basic construction of the clamping aid described.
