Patent DE-4115078-A1 (DE)
Title: Device for optical interconnection of active and passive components of integrated optics - involves optical wave conductor of reinforcement material for active component and optically transparent wave conductor for passive component
Inventor: BAUER ROBERT DIPL ING
IPC: H01S5/40
Filed: 1991-05-08
Abstract: The two wave conductors (10, 20) are arranged to each other in spaced planes, and are optically coupled to one another a specific common coupling stretch (3). The coupling stretch (3) is shorter than each ofthe wave conductors, but longer than a diffusion path electrical charge cararier in the optical reinforcement material. The two wave conductors, at least outside the coupling stretch, are insulated optically and electrically to one another. The coupling stretch has a length (w) which is at least equal to a defined min. length, which suits an optical wave transmiited by complete over-coupling from the wave conductor (10) of optical reinforcement material to that (20) of transparent material. The two conductors (10, 20) are optically coupled to one another via an intermediate layer (12) extending in the area of the coupling stretch and located between them. They only partlly overlap, and the coupling stretch is defined by the overlapping area. USE/ADVANTAGE - In integrated optical systems, with optical coupling of active and passive components, which can be electrically uncoupled for electrical signal processing.

Title: Motor vehicle theft protection system disabling engine ignition - has electronic switching unit and relay and evaluates voltage difference in electrical system between switched off and travelling motor vehicle
Inventor: KLOEDEN PETER
IPC: B60R25/045
Filed: 1991-05-21
Abstract: In the non-activated position of the system, the relay has dropped out and the switching contacts are closed. The lead (15) to the ignition coil or the lead (1) from the circuit breaker to the ignition coil is led over these contacts. The vehicle in this position is in operational readiness. The current supply to the electronic circuit is fed by the vehicle electrical system. When the engine is started it runs at the idling speed, with an effort to move the vehicle, the supply of fuel to the engine is increased, giving a higher engine rpm and an increased voltage in the electrical system. The switching threshold of the electronic circuit is set at 13 volts, the relay pulls in and interrupts the operation of the ignition system. The engine stops and psychologically the impression is given that the vehicle is defective. The electronic circuit can be switched on and off by means of local individually different switch in the vehicle. The switch is fitted in the positive supply line between the electronic circuit and the vehicle electrical system. ADVANTAGE - Wiring is simpler and less costly than system presently used, and electronic circuit needs no special measurement input.

Filed: 1991-06-28
Abstract: The equipment is partic. for injecting pharmaceutical solns. into human or animal bodies, having a gas-generation cell delivering oxygen or hydrogen at a rate determined by an electric current flowing through the cell. A piston divides a cylinder into a chamber accommodating the medium handled and one supplied with propellant gas by the cell. The propellant-gas chamber is connected to the outside by a valve, whose opening mechanism is operated by the piston thrust via a linear component before the piston reaches its end position. The electrical circuit can include a switch in the gas chamber and opened by the linear component. ADVANTAGE - Gas cannot flow past the piston via the needle and into the body.

Title: Single-step coder with source word input - has specified number of source words, with specified work bit width
Inventor: ROEHRBEIN ROLAND
IPC: H03M7/16
Filed: 1991-07-24
Abstract: The coder has an input (E) to which source words (q f) are supplied and a unit (C), in which the binary code words (cf) are generated according to a prescription stored in a memory, or realised by a network. The output (A) transmits the code words. The number of the source words for coding is specified. They are associated to code words with a specified bit width. Each group with a bit width l is fed to a Johnson coder (JS), while a second group with the bit width k is supplied to a Gray coder (GC) either unchanged, or inverted in an inverting stage of a control circuit (S). The change between unchanged and inverted takes place when the code word changes the output of the Johnson coder. ADVANTAGE - Improved coding and decoding process.

Title: Preventing milk sample bottle spillage - during magazine filling in milk sample identification system
IPC: G01N35/04
Filed: 1991-10-26
Abstract: Preventing upset of sample bottles having metal bases, during filling of a circular magazine in a milk sample identification system, is claimed. The magazine has a bottle guide spiral located above a driven magnetic turntable. The novelty is that (a) the rotational direction of the turntable during magazine filling is initially reversed after entry of a sample bottle into the magzine until all the bottles in the magazine are shifted close together; and (b) the turntable direction is then reversed again before the next sample bottle is supplied to the magazine. USE/ADVANTAGE - Useful in milk collection vehicles for collecting samples from various milk prodn. sources. The method produces close packing of the sample bottles to prevent upsetting of the filled bottles.

Title: Detecting phantom keys of keyboard using firmware - using diagnostic program during keyboard polling to detect when phantom conditions occur due to simultaneous operation of keys
Inventor: CHEN CHENG-WEN
IPC: G06F3/023
Filed: 1992-02-28
Abstract: The phantom key detection method involves using a single chip micro computer with a built-in diagnostic program to detect the so called phantom key state conditions when one or more keys are operated together. The keyboard arrangement has a matrix of 8 keys per row and 16 lines creating a matrix of 128 keys. The lines are polled every 8 ms using firmware. When only a single key is actuated only one column is 0 and the others 1 and the keyboard is free of phantom effects. For more than one key at a time the diagnostic process identifies more than one column being 0 and a phantom condition is identified. If phantom condition then stops accepting keyboard input and indicates condition via audio signal. USE/ADVANTAGE - Avoids problem of phantom key operations by rapid detection of this condition. Saves memory space by using firmware.
