Inventor: KUEBLER WERNER DIPL-ING FH
IPC: F04C18/16
Filed: 1991-12-19
Abstract: The invention relates to an internal combustion engine with air compressor. When gearwheels are used to transmit the torque from the crankshaft to the shaft of an air compressor, widely fluctuating torques occur with reciprocating air compressors and these torques impose considerable loads on the gearwheels and, in addition, lead to severe gear noise. In order to avoid this, the invention proposes to use an air compressor which operates on the rotary principle. A rotary compressor has a constant torque characteristic. As a result, the transmitting gearwheels are no longer exposed to these torque fluctuations and their life is thereby lengthened. Since, in rotary compressors, there is no torque reversal due to reverse expansion as in reciprocating air compressors, the gear noises, caused by the impact of the gearwheel flanks, are also considerably reduced.

Abstract: Une enseigne pour détaillants, du type à panneau-balançoire possède un cadre principal sous forme d'un moulage par injection à coeur gazeux, réalisé par exemple en polypropylène. Le coeur gazeux se présente comme une cavité simple qui s'étend le long du rail supérieur (1A), des montants latéraux (1B, 1C) et des parties extérieures du rail inférieur (1D) du cadre. Les régions creuses du cadre, vues en section transversale, sont convexes sur toute leur périphérie afin de faciliter le moulage et en particulier le centrage du coeur gazeux dans la structure moulée. La structure du cadre peut comporter des parties de connexion verticales pour des paires de pieds à pivotement (5) qui peuvent être déplacés depuis des positions perpendiculaires au cadre à des positions alignées avec les plans majeurs du cadre. L'utilisation d'un cadre de section généralement ovale ainsi que d'un rail inférieur (1D) qui n'est pas en contact avec le sol perment de disposer d'une structure qui résiste au renversement en cas de vents violents.

Title: Signal recognition system and method.
Inventor: KENYON STEPHEN C
IPC: G10L15/06
Filed: 1991-05-02
Abstract: Recognizing a signal begins by receiving the signal and sampling it at a plurality of sampling points to produce a plurality of signal values. A statistical moment of the signal is calculated using the signal values according to the formula:  <IMAGE>  where: N=the number of sampling points; n=1<n<N X=the signal value of the signal at the sampling point;  mu =a mean of the signal values;  sigma =a standard deviation of the signal values; and k=an integer greater than 1. The calculated statistical moment is then compared with a plurality of stored signal identifications and the received signal is recognized as similar to one of the stored signal identifications. Preferably, the calculated statistical moment is used to create a feature vector which is quantized, and a weighted sum of the quantized feature vector is used to access a memory which stores the signal identifications.
