Title: Device for recording relative speed of sporting equipment, e.g. skis, ice-skates, snow-boards etc. - comprises slidable scanner on ski contacting snow for successive contact-point time signalling via spaced sensors and lens
Inventor: MEIER JOSEF
IPC: G01P3/50
Filed: 1995-07-07
Abstract: When the ski, snow-board etc. (1) is set in movement, the device fitted to it slidably contacts the surrounding medium and contains a scanner probing an irregularly structured surface of the medium. This produces two or more signals which characterise structural changes of the scanned surface so that the time lag between the two signals can be evaluated to give the speed of the ski. The scanner has a laser anemometer, prism grating, or optical system (19) to optically represent the structure during signal generation. The optical system should lie flush on the medium side to a sliding surface (5) of the ski, using a cylindrical lens system (21) as part of the optical system so the sliding surface (5) forms the subject plane of the system (19). Two sensors (30,31) on the image side of the system (19) are arranged in tandem at pre-set spacing so as to produce the two signals. The sensors consist of photo receivers, photocells, photo-diodes or CCD elements and a re each fronted by a shutter whose slot runs parallel to the longitudinal axis of the lens cylinder (21).

Patent DE-19531675-A1 (DE)
Inventor: DEPPING HERBERT
IPC: F16H61/08
Filed: 1995-08-29
Abstract: The invention concerns a method of operating a vehicle transmission with friction elements which can preferably be actuated electrohydraulically for shifting between various ratio levels in a vehicle having at least one further prime mover. An actual value of at least one variable characterizing the gear-change operation is determined during each gear-change operation and is compared with a predetermined nominal value which can be memorized. If the actual value differs from the nominal value, a correcting variable is altered by a predetermined correction value in order to influence said value at least indirectly. The invention is characterized by the following features: during each gear-change operation, the time interval between the emission of a gear-change signal and the beginning of the synchronization process and/or the variation of the drive speed during this time interval is determined as a first and/or second actual value of the gear-change-characterizing variable; if the time interval until the beginning of the synchronization process differs from the predetermined nominal time interval or if the predetermined drive speed variation is not attained after a gear-change operation, the initial pressure value is varied by the correction value in order to apply the necessary pressure force of the clutch parts which can be interconnected in a force-locking manner.

Inventor: DICKS RALF
IPC: C09J7/20
Filed: 1995-10-06
Abstract: This self-adhesive device, e.g. a hook, is also detachable. Its front is used for holding and the rear has a strip of double-sided adhesive sheet adhering to it, such that an end protrudes beyond the edge of the base plate. This serves as a grip. Pulling the strip here, along the plane of adhesion, stretches it, to release the adhesion achieved, hence freeing it. A novel feature of the device is the grooving of the base region, where the adhesive strip is glued to it. The grooves extend out over the area of the strip. Also claimed is use of a base plate as described.

Title: Microcomputer controller for timing of internal combustion engines, in control system for motor vehicle
Inventor: FUKUI WATARU
IPC: G01D5/245
Filed: 1996-03-13
Abstract: The microcomputer controller (100) receives signals (POSR) from a first detector (81) which notes the turning of the crankshaft (11) and signals (SGC) from a second detector (82) related to the camshaft (1). From these it determines the parameters (P) which control the working of the motor. The first series of signals gives the angle position and the gauge intervals (101), analysed by the microprocessor, which correspond to each cylinder group (102), while the second series is producing the cylinder identification signals. The system allows for identification of the reference position of individual cylinder, resulting in higher accuracy in the timing control. A back-up control is also incorporated which operates a cut-out if any abnormality is determined (105) in the signals received.

Patent DE-19612507-A1 (DE)
Inventor: PLICHTA PETER DR
IPC: F02C3/20
Filed: 1996-03-29
Abstract: The invention relates to a method of driving a shaft by reaction of silanes, preferably silane oils, with air in a double combustion chamber and an associated drive mechanism. The hydrogen of the silanes reacts in the first combustion chamber with an insufficient level of oxygen of the air supplied, thereby producing high temperatures. At said high temperatures, the nitrogen from the air supplied reacts with the silicon of the silane to form silicon nitride. The resultant combustion gases and dust and the non-combusted hydrogen are mixed in the second combustion chamber with a large quantity of cold compressed air, the hydrogen undergoing late burning, and they subsequently enter a turbine chamber to actuate turbine blades connected to a shaft. The method is particularly environmentally-friendly since no toxic or polluting waste gases are produced.

Title: Continuous process method for multicarrier signal
Inventor: JUNG MICHAEL
IPC: H04L25/02
Filed: 1996-05-09
Abstract: The method involves generating a reference transmission factor (Href) for a reference carrier (S'ref) of a multicarrier receiving signal (S') using a multiprocessor (10). Estimates of the transmission factor (H) which describes a transmission channel are determined for a desired carrier by filtering the reference transmission factor. The estimation is used to determine a desired signal (S) which is influenced by the transmission channel.  The estimation involves filtering the reference transmission factor using a low pass unit (14,16) which acts in frequency direction. The output signal of the low pass unit is fed back to additionally low pass filter the difference transmission factor.
