Title: Digitised audio signal electronic recording and playback unit - digitises, compresses and stores input from microphone to solid state memory, and plays back in analogue form to loudspeaker.
Inventor: HOLZER WALTER DR
IPC: G06F3/16
Filed: 1992-03-09
Abstract: The miniaturised unit for the recording and playback of audio signals uses digital signal circuit techniques. The compact unit is microprocessor based and allows spoken messages to be entered via a microphone (12) that connects with an A/D converter. The generated digital signals are transmitted via an interlock circuit that requires a PIN number which is entered via a keyboard (0-9). The digitised data is subjected to a data compression process before being entered into memory. When accessed, with the aid of the PIN number entry, the data is expanded and converted into analogue form for output by the loudspeaker (14). Speech or music may be handled. USE/ADVANTAGE - Solid state digital signal recording. Controlled access. No moving parts, so no sensitivity to vibrations. More compact unit, and easier access to desired part of stored information.

Title: Vehicle speed controller with memory and microcontroller - calculates desired speed from max. acceleration, defined time interval, and stored desired speed using actual speed valves and microcontroller
Inventor: BERNHARD KARLHEINZ
IPC: B60K31/04
Filed: 1992-12-15
Abstract: The speed controller is reactivated by a microcontroller to provide speed valves Vs in defined time intervals, delta (t). The speed valves are obtained by addition of a value delta (v) to a desired valve using the formula: Vsi = Vsi-1 + delta (v), where delta (v) consists of a predetermined value for max. acceleration, bmax, i.e. delta (v) = bmax * delta (t). As long as the actual speed VI is under the stored value Vsp. Delta (v) depends on the difference Vsp-VI. The max. acceleration depends on characteristic vehicle data, motor power, and comfort demands. ADVANTAGE - Stored speed can be reached independent of actual difference between stored value and actual value quickly and smoothly.

Title: Provision of energy conversion systems which are independent of the electric grid, track the radiation source and are self-sufficient, especially photovoltaic systems which may or may not be combined into farms, for collecting energy which can be used at any time
Inventor: BAEHR GOTTFRIED
IPC: F02G5/00
Filed: 1993-04-02
Abstract: Current nuclear-power power supply installations entail considerable costs and problems in installation, repair, maintenance and disposal and decommissioning operations. The invention now demonstrates, in the field of energy conversion, especially that of photovoltaics, the immediate conversion into energy which can be consumed independently at any time, without being fed into a power supply grid. The immediate dissociation of water into oxygen and hydrogen, still within a farm unit is demonstrated. This system is immediately feasible and helps in moving away from nuclear energy, since it circumvents the step, carrying an economic disincentive, of feeding energy into the power supply grid and is thus portable if required. It assists in the introduction of combustion of hydrogen, especially used in engines for motive power, or for heating together with power supply and thus in reducing the ozone hole. It assists in the beneficial and environmentally friendly development of territories no longer used, since the oxygen produced can be used to aerate, simultaneously, polluted waste waters, sewage plants, lakes and ponds.

Title: Method and device for continuous production of stranded material with a constant, predetermined resistance
Inventor: WIEDERHOLD MICHAEL
IPC: G01R31/02
Filed: 1993-09-27
Abstract: The invention is based on the problem of developing a method and a device using which a large amount of conductor-specific data are determined during the stranding and compression process, preferably data which influence the temperature profile of the conductor, and are used to regulate the setting of the compressor roller of a compressor device within a stranding system. The said problem is solved in that the temperature of the surface of the conductor (4) is measured directly at the same time as the resistance of the compressed conductor (4) is measured in the region of the double-pulley outlet (5), the body temperature of the outlet pulley (7; 8) is measured directly, the environmental temperature of the double-pulley outlet (5) is measured and in each case one additional temperature measurement of the conductor (4) is carried out before and after the double-pulley outlet (5), and all the measurements which have been obtained are fed to an evaluation and regulation device (10) in order to regulate the compresor roller setting. The field of application of the invention is primarily in the area of the cable-making industry (stranding industry). <IMAGE>

Title: Optical modulator
Inventor: KUSCH SIGURD PROF DR SC NAT
IPC: G02B27/28
Filed: 1993-11-05
Abstract: The invention relates to an optical modulator in which an interim light beam is split, by means of a double-refracting (birefringent) crystal, into an ordinary beam and into an extraordinary beam, polarised perpendicular thereto. According to the invention, two optically identical double-refracting crystals are arranged in one plane one behind the other in such a manner that their optical axes run with mirror-imaged symmetry relative to a vertical imaginary plane between these two. In this plane, a chopper is arranged, by means of which either the ordinary or the extraordinary beam can be fed to the second crystal, so that an ordinary or an extraordinary light beam, polarised perpendicular thereto, leaves the second crystal coaxially to the light beam entering the first crystal. <IMAGE>
