Title: Signal recognition system and method
Inventor: KENYON STEPHEN C
IPC: G10L17/26
Filed: 1991-05-02
Granted: 2004-12-28
Abstract: Apparatus and method for recognizing a signal, receives the signal and samples 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:    where: N = the number of sampling points: n = 1 < n < N      X = the signal value of the signal at the sampling point: µ = 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 assess a memory which stores the signal identifications.

Title: Scroll type fluid machinery
Inventor: IIO TAKAYUKI
IPC: F01C21/00
Filed: 1991-06-11
Granted: 1994-05-10
Abstract: 7. ABSTRACT         The present invention relates to a scroll type fluid machinery provided with a slide type radius of revolution variable mechanism, and has an object of pre-venting unilateral working of a rotating bearing 23 due to tilted rotation of a drive bushing 21 and a balance weight 27 fixed thereto.         The construction of the present invention is formed in such a manner that a bolt 41 for regulating tilted rotation is projected at an inner end of a rotary shaft 7, a shaft portion 41a thereof is made to penetrate through a vain hole 42 bored in the balance weight 27, and a bearing surface 41c of a head 41b thereof is brought into slidable contact with the inner end surface of the balance weight 27.  When the radius of revolution is varied at the time of revolution in a solar motion of a revolving scroll 14, an eccentric driving pin 25 slides in a slide groove 24 and the shaft portion 41a of the bolt 41 slides in the vain hole 42 at the same time.          In the interim, the bearing surface 41c of the head 41 comes into slidable contact with the inner end surface of the balance weight 27, thereby to suppress tilted rotation of the balance weight 27.

Title: Rigidized fibre filter element
Inventor: JEFFERY ANDREW B
IPC: B01D39/00
Filed: 1993-01-11
Granted: 1996-01-30
Abstract: A rigidized fibre filter element is produced from a precursor  fibre  web  according  to  various  methods.    The precursor fibre web contains heat-shrinkable fibres or binder fibres  or  both.    The  web  is  exposed  to  temperatures sufficiently elevated to cause shrinkage of the fibres or melting of the binder.   After cooling the web, the filter elements produced are self-supporting, and may have densities up to 500 kg/m3 to improve filtration while retaining good functional characteristics for operating pressure drop and air permeability.    Rigidized  fibre  filter  elements  can  be constructed of one material,  and thus may be suitable for recycling.

Inventor: BINNS WALTER PATRICK
IPC: H04M3/56
Filed: 1993-03-29
Granted: 1997-06-10
Abstract: In a video telephony system, a coaxial cable network (121, 126), which is preferably a part of an existing cable television system (121, 126, 122, 127), provides a local link for the transmission of the video telephone signals between each originating and destination location (101, 105) and a respective "head end"(122, 127) located on the cable company premises. Each of the head ends is connected to a "point of presence" (161, 162) of a telephone interexchange carrier so that a connection between pairs of head ends, and thus between a pair of video telephone locations, can be made via a switched digital network (160) maintained by the carrier. Certain of originating and destination locations comprise a standard television set (103, 106), serving as the audio/video display, and a consumer-type camera or camcorder, serving as the audio/video source. Others of the originating and destination locations comprise ISDN video telephones (111, 115) which are connected to the various points of presence of the interexchange carrier via local exchange carrier telephone networks (140, 145). The video telephone numbers for cable subscriber locations are administered to be the same as the standard ten- (i.e., area code plus seven-) digit telephone number used for regular telephone calls directed to those locations.

Filed: 1991-11-26
Granted: 1998-11-03
Abstract: An apparatus and method is described for transmitting, receiving and communicating program data signals which are combined with digital data signals. Preferably, the present invention compresses 30 digital audio signals (10-1 - 10-n), multiplexes them with title, track, artist, record label, year, etc., program information (20-1 - 20 m and 30-1 - 30-K), and transmits the combined signals via satellite (50) to a receiving station (60). The receiving station demultiplexes (70) the signals and sends them via a cable distribution system to a subscriber's digital music tuner (100). This tuner further demultiplexes (143) and decodes (147) the signals so that the digital audio signals may be converted to analog (160) and output for listening. while the corresponding data signals are communicated to the subscriber. In an alternative preferred embodiment, the program data signals are transmitted to a remote control receiver (200) where they are displayed. The system described in the present invention may be used for transmitting video, software or games with program data to subscribers.
