Patent DE-19531133-A1 (DE)
Title: Fuzzy logic control of a through-flow water heater
Inventor: KRONBERG MANFRED PROF DR ING
IPC: G05B13/02
Filed: 1995-08-24
Abstract: A through-flow water heater has a pipe in which there are two heating stages 4,6 each having pair of electrical resistance heating elements 4a,4b;6a,6b. The temperature of the output of each stage is measured by a sensor 8,10 and the output signals fed back to controllers 12a,12b that control the activation of the heater elements. The control action is based upon a fuzzy logic control algorithm in which actual temperature values are used with reference temperature variations in fuzzy sets.

Title: Traffic control method for packet-switching communication equipment e.g. ATM
Inventor: MASAKI FUMITOSHI
IPC: H04L47/22
Filed: 1995-08-29
Abstract: The method initially involves receiving packets at nodes and calculating dispatch times for them according to a predetermined band-width distribution.  The packets are stored in a packet memory (105), according to the dispatch time, and then transferred to an output queue for transmission at their respective assigned dispatch times. Packets with the same dispatch time are transmitted together, and packets are supplied in succession from the output queue.

Title: Assessing loudspeaker timbre for stereo systems
Inventor: BRAUN DIETER PROF DR
IPC: H04S1/00
Filed: 1995-09-18
Abstract: A measurement process for judging the timbre of loudspeakers (1) in stereo systems requires production of a synthetic or natural test signal series from a two-channel source and transmission of the signal to the speakers, set at some distance from one another. The degree of electrical coherence is then determined by cross correlation between the two channels. The sound amplitude emitted from both speakers can be measured by an artificial head (2), with two artificial ears as measurement channels, positioned equidistantly from them. The acoustic coherence between the two artificial ears should then be determined as a function of time. The correlation between the electrical coherence and the acoustic coherence may be used as a measure of judgement for sound quality from the loudspeakers.

Patent DE-19600297-A1 (DE)
Inventor: CHANEY RAYMOND JOHN
IPC: G01B9/02
Filed: 1996-01-05
Abstract: A laser interferometer for calibrating displacement has a linear array of elongate parallel photosensitive elements (70) situated in a spatial fringe field created from interfering beams having non-parallel directions of propagation. The elements are grouped into sets in an interleaved repeating pattern. Movement of a retroreflector (48) causes a detectable shift in the fringe field. The apparatus includes a beam splitter (44) creating a pair of orthogonally polarised beams. One of the beams is diverted into relatively fixed retroreflector (46), the other passes undiverted into retroreflector (48). The beams recombined at beam splitter (44) are partly overlapping and parallel. A birefringent prism (60) refracts the beams through different angles causing them to converge and polarising element (62) mixes their polarisation states so they interfere and generate a spatial fringe field. The apparatus may also calibrate angular displacement, straightness, squareness, pitch roll or yaw on a machine tool. <IMAGE>

Abstract: The catalytic converter (3) in the exhaust duct (2) has an electric heater (4) upstream to heat the exhaust gasses if the converter is not operating at its optimum temperature. The self analysis control monitors the effectiveness of the converter and measures the amount of heating required to maintain the operation of the converter, especially at idling speed.
