Patent DE-19628836-A1 (DE)
Title: Airbag with valve control for motor vehicles
Inventor: SCHELS MARKUS DIPL ING
IPC: B60R21/276
Filed: 1996-07-17
Abstract: The airbag has at least one valve-controlled discharge aperture to the atmosphere. The valve element (14) automatically regulates the size (20) of the discharge aperture (13), dependant upon the impact of the vehicle passenger (18) on the inflated airbag (12), and the internal airbag pressure variations caused by this load. The element progressively closes the aperture with increasing internal pressure, and opens it when the pressure decreases. The pressure inside the airbag is used as a standard value for automatic position adjustment of the valve element relative to the discharge aperture. The valve element consists of a spring-loaded (16) pressure plate.

Title: Acoustic echo reduction method for hands-free telephone set
Inventor: MARTIN RAINER DR
IPC: H04L27/01
Filed: 1996-09-26
Abstract: The method involves feeding a difference signal (e(k)) to a controllable filter allocated to the transmission path of an acoustic echo. The difference signal is formed from the output signal of a microphone (y(k)) and the output signal of an echo canceller. The echo canceller is coupled to a reception path of the acoustic echo. A loudspeaker is coupled to the output of the echo canceller. The filter is controllable using a mixing signal ((z(k)) formed by mixing the microphone signal with the cancelling signal (dd(k)).  A factor (alpha(k)) for the compensation signal is formed with which the compensation signal goes into the mixing signal. The factor is formed with respect to the microphone signal power or the difference signal and the compensation signal. The factor is greater than one.

Title: Ultrasonic flowmeters measuring water depth and current speed e.g. for river
Inventor: CHANG HAK SOO
IPC: G01F1/66
Filed: 1996-11-27
Abstract: Ultrasonic flowmeters in pair are based on a catamaran-form floating platform (7,7'). This has a central deck (8) carrying a sender/receiver (15), ultrasound vibrators (10,11) for determination of water depth and ultrasound speed, and pairs of vibrators (12,12',13,13',14,14') for determination of current speed.

Title: Automatic transmission lubrication system
Inventor: MIZUTA MUNEO
IPC: F16H63/12
Filed: 1997-02-06
Abstract: The multiple clutch plates (35,43) are engaged and disengaged by means of pistons (34) each acting axially on respective plates and in this way reversing the rotation of the planet gearing (46) and so changing the gear transmission ratio of the drive force. Second multi-plate friction elements within the lubricating system engage in the return movement and adopt the same position as the first set of plates in the axial direction but outside these first plates in the radial sense. The brake piston, (34) used to drive the first plates, may shift the drive gear ratio to give four forward speeds and one reverse obtained by engaging the plates in the second speed gear and in the fourth speed gear and by disengaging the plates in a third speed gear. The two sets of plates overlap one another in the axial direction. Pumped oil may lubricate and cool the 2-4 brake clutch (33) and then brake clutch (40).

Patent DE-19710341-A1 (DE)
Inventor: KRAUSPE MANFRED
IPC: B60S9/12
Filed: 1997-03-13
Abstract: The hydraulic or mechanical support especially for rail vehicles with hoisting apparatus or other apparatus that deliver an increased stationary torque on the vehicle, has a control system present which works automatically by measuring the change of distance between the vehicle frame (3) and parts rigidly connected to it, like the axle bracket (6), the wheel set and parts belonging to the wheel set, like the axle housing (4). The distance is then for each vehicle a constant size dependent on the vehicle construction and the springing used. The distance is measured by a proximity switch (7) or other suitable transmitter and works as an input signal to an electrohydraulic or electromechanical control unit. By controlling the distance, not only hydraulically but also mechanically working vehicle supports can be controlled.
