Patent DE-4236774-A1 (DE)
Inventor: LEPPING JUERGEN
IPC: H04M1/72505
Filed: 1992-10-30
Abstract: For demodulating modulated carrier signals (AS) supplied to a cordless telecommunication apparatus, a data comparator (1212) is used for cordless information transmission, in particular DECT-specific information transmission. A reference signal (RS) generated by integrating the carrier signal (AS) is supplied to an input (E2) of the data comparator (1212) for demodulating the carrier signal (AS). Since according to the DECT transmission agreement, two identical binary values of a synchronisation word (S-BW) must be recognised besides the demodulation, a decision threshold (ES) of the reference signal (RS) is modified by an error value (dES). An additional compensating arrangement (16, 9, 142) which compensates said error value (dES) is therefore provided in the cordless telecommunication appliance.

Title: Vehicle anti-collision radar system - detects distance to object in front of radar system vehicle using laser beam and read gradient detector and determines whether or not object is vehicle
Inventor: HIBINO KATSUHIKO
IPC: G01S13/931
Filed: 1993-12-07
Abstract: The radar system derives distance data for distance between the vehicle radar system and an object in the detection region. A curve detector determines the gradient of a street or road on which the system vehicle travels. A probability determiner calculates the probability that the detected object is a vehicle. The probability is determined based on distance data and curve or gradient data. The rate of change of object speed is determined to determine the required speed of the system vehicle. A laser beam or EM wave is used to determine the distance to an object in front of the system vehicle. ADVANTAGE - Minimises errors due to detection of vehicles on different road lane, advertising boards, street signs, lamp posts, etc..

Patent DE-4405299-A1 (DE)
Inventor: LEGNER JUERGEN
IPC: F16H61/06
Filed: 1994-02-19
Abstract: The invention relates to a power shiftable two-speed gear in the form of a planet gear (3). The two ratios can be hydraulically shifted via two friction clutches (9 and 10).

When this is in operation, it filters with the same retention characteristics as the individual filter itself. In addition to the above method, the appts. to carry it out, is also claimed.
Patent DE-4409832-A1 (DE)
Title: Display device of the gas-discharge type and method for its production
Inventor: NAKAJIMA FUMIO
IPC: H01J1/30
Filed: 1994-03-22
Abstract: A plate-shaped display device of the gas-discharge type has an anode and a cathode, which cathode has a specific form for the purpose of improving the discharge in an airtight chamber which is formed by two substrates. A gas, which contains a gas which emits ultraviolet radiation, such as for example Xe and Kr, and a fluorescent (luminescent) material for emitting light are jointly inserted into the airtight chamber. As a result of the shape of the cathode, there is more discharge than in the case of devices according to the state of the art. A stronger ultraviolet emission as a result of the discharge excites the fluorescent material to generate a visible radiation. The brightness of the device is increased thereby. Since the cathode is coated with an emitter material which is incapable of absorbing the gas which emits the ultraviolet radiation, what is achieved is that not only is the discharge not impeded by the reduction of the gas which emits the ultraviolet radiation, but also the colour of the visible radiation can be maintained in a stable manner.
Patent DE-4410918-A1 (DE)
Title: Capacitive device for rotational distance and/or position measurement around axis
Inventor: SEEWANG PETER DIPL ING
IPC: G01D5/241
Filed: 1994-03-29
Abstract: The device has a sliding plate (2) forming a capacitor surface, which can be continuously manually adjusted with respect to a central position, and fixed capacitive counter surfaces (C1,C2). Alternating voltages offset by 180 deg. are applied to the counter surfaces. Each plate position corresponds to a capacitive characteristic inversely related to the effective capacitive surface of the plate. The relative capacitive characteristic is detected by a bridge circuit. The fixed counter surfaces are divided into sub surfaces arranged in symmetrical Cartesian or polar coordinate effective surface sections. Two capacitor counter surfaces lying opposite each other in Cartesian or polar coordinates are supplied with out-of-phase alternating voltages in the X and Y axes. The signal can be tapped directly from the plate using a bridge circuit or via a neutral capacitor surface (C3).
