Title: Error detection in digital transmission of audio signals - identifying erroneous jumps in level of signal by deviation from value in statistically more probable sequence
Inventor: PLENGE GEORG
IPC: H04B1/66
Filed: 1992-01-31
Abstract: When jumps occur in the level of the received signal (1a) or in selected components thereof, the sequences received before and after a jump (1b) are compared with sequenced corresp. to the signal statistics. When the sequence shows an isolated increase (1c) or decreases (1d), jumps in excess of a defined threshold are identified as errors in transmission if their value deviates from the statistically expected sequence. A probable correct scale factor is easily substd. either by extrapolation from the preceding value or by interpolation between values accepted as correct. ADVANTAGE - Detection at receiver is improved esp. for errors in particular signal components.

Inventor: LHYU JAE-CHON
IPC: G03B15/00
Filed: 1992-07-14
Abstract: An image area indicating device 30 usable in a camcorder 10, uses laser beams 40a to 40d for indicating the extremities of an image area 500 by laser beam images a, b, c and d, the positions of which are adjusted in accordance with the setting of a zoom lens 20.

Title: Semiconductor DRAM component with sense amplifier - charges bit lines with different high reference voltages, to exceed input offset voltage of amplifier
Inventor: NAKAMURA NOBUO
IPC: G11C11/409
Filed: 1992-12-11
Abstract: The memory (DRAM) has a dynamic memory cell (MC), a couple of bit lines (BL,BL) connected to the memory cells, a flip-flop (12) to refresh the memory, a work-line (WL), a differential sense amplifier (10) and NMOS transistors (Q921,Q911,Q922,Q912) used as switch. The sense amplifier (10) is built from high performance current mirrors with active loads to reduce input-offset-voltage. When the bit line (BL) is connected to the voltage reference of 1/2 Vcc by switching the NMOS transistor (Q921) on, the inverted output of the amplifier is feedback to the bit line (BL) through the NMOS transistor (Q911). Supposing that input-offset-voltage of the amplifier is delta V. The bit line (BL) voltage becomes 1/2 Vcc + delta V, the delta being small compared to 1/2 Vcc, therefore it can be tolerable. ADVANTAGE - Complications of input-offset-voltage are avoided.

Patent DE-4303977-A1 (DE)
Title: Float
Inventor: GUHLMANN PETER DIPL ING
IPC: B63B35/73
Filed: 1993-02-08
Abstract: The float invention contains bodies made of porous, silicate-containing materials. It begins therefore with a floating block in an ornamental pond, progresses to a bathing island in the village pond and can be extended via a lighthouse island in the reed area to the construction of inhabitable atoll islands in the ice-free high sea. Ultimately, with coordination with international interests, in particular seafaring, large sections of the ocean can be converted into inhabitable areas. Glass residues and glass bases with a specific gravity of 2.2-3.1 g/cm<3> are, to manufacture the blocks, heated above 800@C until vaporisation of an additive such as soot, carbonised paper, plastics, which additive forms bubbles on further raising of the temperature, and at the same time waste materials can also be included. The tempered closed blocks can, walled together, be sealed by bitumen masses and pressed and anchored in steel reinforcements and metal shells. High-seaworthy atoll-like islands have floodwater channels in the interior, glass-roof greenhouses, harbour gates, vertical shafts through which, in the swell, water runs off and generates energy etc.

Abstract: The invention relates to an optically integrated polariser which comprises a substrate body, along whose surface a strip-shaped optical waveguide extends which is produced by diffusing titanium into it and which has a proton-exchanged region at least on a part of its length. It is essential for the invention that the proton-exchanged region also extends on the two sides of the titanium waveguide into the substrate body and that this region has an overall width amounting to a multiple of the width of the waveguide and is designed in such a manner that its depth in the region of the titanium waveguide is smaller than in the substrate body on the two sides of the waveguide. The invention furthermore relates to a method for the production of such a polariser.

Title: Method for two-dimensional or three-dimensional imaging of an examination region and arrangement for carrying out the method
Inventor: KUHN MICHAEL DR-ING
IPC: G01R33/567
Filed: 1993-03-06
Abstract: The invention relates to a method for two-dimensional or three-dimensional imaging of an examination region, in which a set of raw data is repeatedly measured, it being possible to reconstruct an image of the examination region from each set and the raw data of a set being picked up with various measuring parameters and different sets containing raw data picked up with the same measuring parameters. In this case, improved temporal resolution is achieved in that, in order to generate an image, representing the examination region at a selectable time point, from at least two sets of raw data, a set of auxiliary data is formed, and in that the auxiliary data are derived by interpolation of raw data determined, in each case, from the same measuring parameters but at different measuring time points, in that the weight with which the raw data are included in the interpolation is proportionately larger the smaller the temporal separation between the corresponding measuring time point and the selectable time point, and in that the image of the determination region is reconstructed from the set of auxiliary data.   <IMAGE>

Title: Estimating gripping properties of road surface w.r.t. vehicle wheels - deriving slip limit value from wheel angle signal and slip signal from wheel speeds, using predefined relationship to derive grip value
Inventor: ANDER ANTHONY T
IPC: B60W10/00
Filed: 1993-11-11
Abstract: A number of periodically generated state signals representing the driving characteristics of the vehicle enable an approximate estimation of the road surface grip. Speed signals are generated for the driven and following wheels. A slip signal is derived from the speed signal difference. A wheel angle signal corresponds to the angle between the steered wheel and the longitudinal vehicle axis. A slip limit signal represents a predefined slip value dependent on the wheel angle signal. A value of a state signal is stored for real time estimation of the surface grip. USE/ADVANTAGE - Measuring coefft. of friction of road surface, e.g. for road covered with ice or snow. Enables very accurate estimation of road surface grip wrt. wheels of vehicle with driven and undriven wheels.

Inventor: WANNKE DIETMAR DIPL ING
IPC: G01S13/78
Filed: 1993-12-08
Abstract: The arrangement consists of a transmitter unit (10) and a receiver unit (1) which functions as a semi-passive transponder, taking its power from the transmitted signal. The receiver unit, installed in the wanted vehicle, sends back identification data whole or in parts to the transmitter unit, which is placed in the general area of the vehicle. The transmitter unit may be stationary or attached to another mobile vehicle. The transmitter unit can compare any part of the identification data that are sent back to it with the respective part for wanted vehicles. When part of the identification data of a wanted vehicle is received, further parts of the data can be received and checked. When all identification data for a wanted vehicle have been recognised, an alarm signal can be sent out.

IPC: H04B5/00
Filed: 1994-04-17
Abstract: In the proposed device (1) for transmitting data between an emitter module (M1) and a receiver module (M2) which can move relative to each other, one of the modules (M1) is an electrically conductive line (L) with a defined characteristic impedance and the other module (M2) is a pick-up (S) which can couple with the line (L) without coming into contact with it.
