Patent DE-19719381-C1 (DE)
Title: Computer based speech recognition method
Inventor: HAUENSTEIN ALFRED DR
IPC: G10L15/02
Filed: 1997-05-07
Granted: 1998-01-22
Abstract: The method includes the steps of digitised a speech signal with a pre-settable clock rate, and transferring the digitised speech signal at each sampling point which is determined through the clock rate, into a characteristic vector. A first difference of the characteristic vector to a first pattern vector is determined, in which the pattern vector presents respectively a smallest distinguishable sound unit with a pre-settable context degree, which indicates how far the context of a sound unit extends.  A first minimum of the first differences is selected. A pre-settable range around the first minimum is selected, and the second differences of the characteristic vector to second pattern vectors are determined in this range, which present respectively the sound units with higher context degree than the smallest distinguishable sound unit. A second minimum of the second differences is selected. The characteristic vector is classified through the sound unit achievable by the second minimum, or, if a more exact classification is necessary, the second minimum is assumed as the first minimum, and a new range is considered around it. Speech is recognized from the combination of classified sound units.
Patent DE-19719547-C1 (DE)
Title: Digital oscillator for desynchronizer in communications system
Inventor: BAYER JOHANNES DIPL ING
IPC: G06F1/08
Filed: 1997-05-09
Granted: 1998-11-12
Abstract: The digital oscillator generates a target clock (ZT) by variably dividing a working clock (AT) with first and second factors. An oscillator (Q) generates the working clock whose positive and negative edges trigger first and second divider circuits (TS1,TS2) which alternately receive a control word (SW) contg. at least one bit via a controlled switch (S1). A second switch (S2) alternately switches the divider circuits to a single output for the target clock.  Each divider circuit contains a logic module for detecting an storing the occurrence of each positive or negative control word edge. The logic module causes a controlled changeover of the second switch in response to detecting a control word edge so that the working clock is divided by a second factor whilst maintaining the low or high level duration constant.

Title: Interferometric measuring arrangement for sensing rough surfaces
Inventor: DRABAREK PAWEL
IPC: G01B11/24
Filed: 1997-05-26
Granted: 1998-06-04
Abstract: The invention relates to an interferometric measuring device for measuring form on rough surfaces of an object, comprising a unit for producing a beam, said unit emitting a short-coherent beam and a beam-splitting device for producing a reference beam which is directed onto a device with a reflective element for periodically altering the path of light and a measuring beam which is directed onto the object. The inventive device also has a superimposition element on which the measuring beam coming from the object and the reference beam coming from the device are caused to interfere, and a photo sensor for recording the interfered beam. The invention provides a simple construction which nonetheless guarantees highly accurate measuring. The device for altering the light path has a parallel displacement system which is positioned in the path of the beam, the reflective element being placed in a fixed position behind said parallel displacement system. A compensation grating is also located in the path of the reference beam, in front of the parallel displacement system. The reference beam is diffracted on said compensation grating both before and after passing through the parallel displacement device.

Title: Sensor detecting ferromagnetic particles in fluids, particularly suitable for monitoring wear
Inventor: SEIFERT BODO-SIEGFRIED
IPC: G01N33/28
Filed: 1997-07-22
Granted: 1998-11-19
Abstract: Metal particles forming impurities in a flow of fluid (16) are measured by this new sensor (1). It has a permanent magnet (17) connected to one pole of a source of electricity. This magnet is surrounded at the sides by an insulator (20), isolating it from the body of the casing (16). The casing is connected to the other pole of the same source of electricity. The casing has a fastening section (18), e.g. an external screw thread, for attachment into the wall of a flow channel. The end faces of the magnet, insulation and casing project into the flow channel. As metal particles collect between the pole and casing, they bridge the insulation, lowering the electrical resistance in the circuit.

Title: Energy-absorbing buffer for motor vehicle bumper incorporates devices for low and high collision speeds, that for low collision speeds being plastically deformable
Inventor: KRAEMER JOHANN
IPC: B60R19/26
Filed: 1998-12-24
Granted: 2000-07-27
Abstract: The low and high collision speed energy-absorber for a motor vehicle bumper is a plastically deformable tube running in the vehicle longitudinal direction. The deformation tube (5), at least over a part of its length, is connected coaxially with a tension casing (10) made of a shape memory material.  The tension casing, on heating, undergoes a diameter alteration with effect from a defined value, which causes an increased friction between it and the deformation tube. The tension casing is connected to the deformation tube with a friction value such that, with a relative movement between them on the basis of a collision speed greater than 50 km/per hour, a heating of the tension casing due to diameter alteration occurs because of the friction.
