Patent DE-19749005-A1 (DE)
Inventor: REIMANN GERD
IPC: B62D5/04
Filed: 1997-11-06
Abstract: The inventive device and method are used for regulating motion quantities representing the movement of a vehicle. The device contains first elements for detecting the quantities representing the movement of the vehicle. It also contains at least two controllers which, independently of each other and with the help of suitable actuators, intervene in order to stabilize the vehicle, basing their action on the quantities detected using the first elements. At least one of the controllers acts on the steering of the vehicle; at least another controller acts on the brakes and/or the motor of the vehicle, and/or another controller acts on the chassis actuators. In addition, the device has a second set of elements for determing signals and/or quantities on the basis of the quantities detected by the first elements. These signals and/or quantities temporarily influence at least one of the two or more controllers in such a way as to stabilize the vehicle. During this procedure, at least one of the two or more controllers intervenes to stabilize the vehicle, as long as it is not influenced by the second set of elements. This continues until it is influenced by the signals and/or quantities determined by means of the second set of elements.

Title: Autonomous data radio network organization
Inventor: ROHLING HERMANN PROF DR
IPC: H04L12/56
Filed: 1997-11-08
Abstract: Each radio station measures continuously the momentary field intensity in a common channel during the first time frame without demodulation of the received signal. A section (S3) with a starting time point (T3), in which the field intensity lies underneath a threshold value, is identified as free, and the message to be transmitted to other stations, is send in a number of following period frames (Z2,... Z4) in the identified free section. The method involves organizing a data radio network with an amount of involved, movable radio stations, whereby all radio stations access the same radio channel, actively and passively. Each radio station determines arbitrarily a starting time point (T0) for a time frame (Z1) which repeats itself continuously. Each radio station measures continuously the momentary field intensity in the channel during the first time frame without demodulation of the received signal.  A section (S3) with a starting time point (T3), in which the field intensity lies underneath a threshold value, is identified as free, and the message to be transmitted to other stations, is send in a number of following period frames (Z2,... Z4) in the identified free section. The radio station measures the field intensity continuously in the remaining time of the respective following period frames (Z2,... Zn), and uses a different period for the transmission at overstepping of the threshold value.

IPC: D03J1/08
Filed: 1998-02-19
Abstract: The cutting mechanism at a loom has a swing body (18) with a fitted cutting blade carrier (2). The electromotor (4) for the drive operates the moving cutting blade (5), in a swing movement round the center axis (6a) of the blade bolt (6). The cutting unit also has a fixed blade (3). A rotary axis (7), fixed to the machine, is at a gap from the blade bolt (6) for the sprung cutting unit (1) to swing round its center axis (7a) on the plane of the woven fabric (8) supported at the spreader (16). A sprung guide for the cutter (1) is held in contact with the selvage of the woven fabric (8), held at a fixed part (2,3) of the cutter (1) and at a gap from the blade bolt (6). The fixed part of the cutter is the blade carrier (2) or the fixed cutting blade (3). The sprung guide has a U-shaped profile (9a) and a pin (9b) carried at an end side of the profile. The cutter (1) swings round the center axis (7a) of the rotary axis (7) between limits at the fabric side and the catch side. The limit at the fabric side is at a gap from the cutter (1) which equals the maximum fabric contraction after the spreader (16). A spring is at the grip surface away from the rotary axis (7), to act on the cutter (1) and the guide. The spring force on the cutter is adjustable. The pin (9b) is held (10) at the blade carrier (2). The center axis (10a) of the pin holder (10) is set at the blade carrier (2) so that the guide is in contact with the selvage after the cutting point of the blades (3,5). The position of the guide can be set in relation to the fabric selvage.

Abstract: The method involves the input signal being converted into a quasi-analog signal by a floating point representation. The converted signal is then processed by a psycho-acoustic filter, so affecting the frequency response inversely to the human hearing response curve such that regions of high hearing sensitivity are lowered in their loudness. The filter output is quantized with the destination word width (N+X), and the quantized data word is then added to a noise signal of the same width (N+X).

Title: Motor control unit for vehicle
Inventor: TOYOHARA MASAHIRO
IPC: F02D41/30
Filed: 1998-06-16
Abstract: The control unit has a processing unit (26) to receive operating state signals e.g. engine crank angle signal, gas pedal activation signal. It calculates control values for a task on the basis of a specific signal, or on the basis of a signal received in a preset time, according to a preset program, in a time period between the signals. An appts (402,403) limits or counts the number of executions of an interrupt triggered by the task activation signal. The processing unit determines the duration of a fuel injection on the basis of an engine crank angle signal, in the time period between crank angle signals. In the case of a poor mixture combustion, the number of interrupts is limited or counted so that at least one fuel injection occurs in the tie between the crank angle signals.
