Title: Method for determining the yaw velocity of a vehicle
Inventor: JACOBI STEFAN DIPL PHYS
IPC: B62D7/15
Filed: 1993-05-05
Abstract: According to the invention, in a first step the circumferential wheel speeds are calculated on the four wheel speeds. The circumferential wheel speeds are used to select that axle whose wheels are running with a slight slip. The yaw velocity of the vehicle is determined from the difference between the wheel circumferential speeds of these two wheels. It is corrected by a factor which is determined from quasi-stationary (quasi-steady-state) circular drives. This factor compensates inaccuracies which are a function of the lateral (transverse) acceleration and are caused by the attitude (slideslip) angle.

Title: MOS power switching circuit IC with short circuit protection - has current limiter between source of MOS power transistor and base of bipolar transistor
Inventor: THRONGNUMCHAI KRAISORN
IPC: H01L23/62
Filed: 1993-05-14
Abstract: The power MOS switching device consists of output transistor (101), with associated MOS device (102), current sense resistor (104) and bipolar transistor (103). The current-voltage characteristic is: Id = KVds (Vin - B Rin / Rb x Vds + B Rin / Rd x Vf - Vt). For normal operation, as the drain voltage increases, an increasing current in (102) causes (103) to turn on, limiting the gate drive voltage (G). In the saturated state for (101) the drain voltage is proportional to current. When no gate voltage is applied, both (102) and (101) are cut off, switching off the leakage current Id. ADVANTAGE - Prevents damage due to overheating when load is short-circuited.

Title: Anti-theft device as an immobiliser on a motor vehicle
Inventor: BOIS WILHELM DIPL ING
IPC: B60R25/04
Filed: 1993-05-21
Abstract: The invention relates to an anti-theft device as an immobiliser on a motor vehicle having a vehicle key (31) in which a transponder (33) is integrated and having an ignition lock (32) in the vicinity of which a transmission coil (36) with connected read-out and evaluation electronics (37) is located. In a control unit, the transponder code which is received from the triggering electronics (37) when the ignition switch is actuated is compared with a stored code for identification. In the event of identity of the codes, a component (40) whose operation is blocked when the vehicle is parked is enabled again. According to the invention it is proposed, in order to reduce costs of such an anti-theft device, that at least some of the components contained in the combined instrument electronics should also be used for additional functions, at least for some of the functions required in the read-out and evaluation electronics and in the control unit. <IMAGE>

Filed: 1993-06-21
Abstract: The invention relates to a device for the open-loop and closed-loop control of mechanical and electromechanical equipment, for example light-protection equipment, which operate independently, without manual influence, exclusively as a function of temperature and material expansion differences and without the use of external energy or fault-susceptible electronics.

IPC: H03H21/00
Filed: 1993-09-27
Abstract: The invention relates to an arrangement for correcting the linear and nonlinear transmission characteristics of electroacoustic transducers which convert an electric quantity into a mechanical or acoustic quantity. The arrangement consists of a variable linear or nonlinear correction filter (1) which is coupled to the electric terminals of the sound transmitter (11), a sensor (12) which measures an electrical, mechanical or acoustic quantity at the sound transmitter, a differential amplifier (17) which compares the measured signal with a nominal signal and determines an error signal, and a control system (24) which produces an adaptive adaptation of the correction filter to the transducer. The control system contains a linear transmission element (25) which connects the output of the differential amplifier (17) to the input of a multiplier and, for each parameter of the correction filter, a linear transmission element (53) which connects the reference signal output (7) of the correction filter (1) to the other input of the multiplier. The arrangement allows an adaptive adaptation of the correction filter (1) to the sound transmitter (11) during the transmission of the useful signal and automatically compensates for parameter change of the sound transmitter (11). <IMAGE>

Title: Filter loading indicator
Inventor: JECKEL ALFRED DIPL ING
IPC: B01D46/44
Filed: 1994-04-15
Abstract: The invention specifies a filter insert for an air filter device, in particular for cleaning the outside air fed to a passenger cell of a motor vehicle. The filter insert is composed of a particle filter layer, in particular of fabric fibres. The particle filter layer contains a monitoring filter region which, in relation to the entire area of the filter layer, is small and which, although air-permeable, has a greater flow resistance than the rest of the filter layer which surrounds the monitoring filter region. Only when the rest of the filter layer is heavily loaded by means of the drawn-in and passing- through air which contains dust or dirt particles and hence there is no longer a large difference in the flow resistances, is the monitoring filter region likewise more and more heavily loaded. In this region there likewise forms a grey shade which increases in intensity, can be visually detected and which can be used to draw conclusions as to the degree of soiling of the rest of the filter layer.

Title: Method for estimating the state of road traffic and method for controlling an operational characteristic of a vehicle
Inventor: MOMOSE NOBUO
IPC: F16H61/66
Filed: 1994-08-10
Abstract: A method for estimating the state of road traffic and for controlling an operational characteristic of a vehicle is carried out by means of a device which has a control device with a fuzzy logic function and neural network function. The control device carries out a frequency analysis for vehicle driving parameters such as e.g. the speed of a vehicle, the steering angle, the degree of opening of an acceleration device and the longitudinal acceleration and the lateral acceleration of the vehicle in order to use them to determine a mean value and a variant of each parameter. This brings about a fuzzy logic on the basis of a ratio of driving time, an average speed and an average lateral acceleration which are obtained from the speed of the vehicle and/or the steering angle in order thereby to calculate the parameters for the state of the road traffic, specifically including a measure of the area of the town, a measure of the road congestion and a measure of the gradient of the carriageway. According to the neural network function, the control device also determines an output parameter which is characteristic of the manoeuvring state of the vehicle in that the mean value and the variance of the vehicle drive parameters and the weighted overall sum of the parameters of the state of the road traffic are subjected to a non-linear conversion. Then, controls the operating characteristics of a device mounted on a vehicle is controlled in a variable way such as e.g. a ... Original abstract incomplete.
