Patent CA-2116255-C (CA)
Inventor: FLANAGAN RICHARD THOMAS
IPC: H04B7/005
Filed: 1994-02-23
Granted: 2000-03-07
Abstract: PREDISTORTION TECHNIQUE FOR COMMUNICATIONS SYSTEMS Abstract The problem of noise enhancement is eliminated in communications systems by predistorting the amplitude of the transmitted information signal in a manner which compensates for the amplitude distortion introduced in a portion ofthe communications channel. In the disclosed embodiments, the communications system includes two signal transceivers which communicate with one another through a communications channel. The communications channel includes two-wire subscriber loops adjacent to each signal transceiver with a four-wire transmission path disposed between the subscriber loops. Each transceiver transmits an information signal which, depending on the system noise characteristics, is predistorted to compensate for all or a portion of the amplitude distortion introduced in a subscriber loop adjacent to that signal transceiver. The predistortion necessary to provide such compensation is determined at each transceiver in response to a received narrowband signal at that transceiver. Advantageously, this narrowband signal may be that used to disable echo cancellers and/suppressors in the communications channel.

Title: Food article filling head
Inventor: PHELPS JAMES M
IPC: B65B19/34
Filed: 1994-04-05
Granted: 2004-11-23
Abstract: A filling head for loading food articles such as franks into individual packaging trays is adapted for quick connect to a power system and a loader parent machine. The filling head comprises an open frame, at least two spring loaded flapper doors hingeably attached to the frame, and a pusher bar unloading system capable of operable connection to the power system of the parent machine to intermittently discharge food articles from the filling head to the individual packaging trays positioned below the flapper doors. The pusher bar unloading system includes a drive rod which can be connected to the periphery of a flywheel by quick connect means to run in an smooth continuous reciprocating motion to deliver an up and down motion to a horizontal shaft slideably mounted on the frame and an associated set of pusher bars and elongated pusher members. The elongated pusher members at the bottom of the drive rod stroke forces food articles in the filling head to open the flapper doors and drop the food articles into the packaging trays.      The filling head has quick connect features which allows the use of different filling heads constructed to deliver different food article arrangements into packaging trays.

Inventor: SCHOEFFLER MAX S
IPC: G10L15/00
Filed: 1994-10-06
Granted: 1997-12-16
Abstract: In a speaker verification system, a method of compensating for differences in speech samples obtained during registration and those obtained during verification due to the use of different types of microphones is provided by filtering at least one of the samples such that the similarities of the two samples are increased. The filtered sample is used within the speaker verification matching process. A two-way comparison is disclosed in which both a verification speech sample and areference sample are filtered with nonlinear microphone characteristics such as carbon microphone characteristics. A four-way comparison is also disclosed in which patterns produced from unfiltered verification and reference samples and patterns produced from the filtered verification and reference samples are compared to identify a match. A score is determined for each comparison. The comparison having the best score is used to determine if a match has occurred.

Abstract: This invention provides a dry butter-based flake product for incorporation into baked goods and flour confections, and methods of manufacture. The dry butter-based flake product comprises from substantially 0 to 2 % moisture, from about 20 % to about 60 % try dairy solids, and the balance is a butterfat. The dry dairy solids are naturally occurring milk solids from which substantially all water has been removed. The method of manufacture provides for mixture of the ingredients so that the solids are suspended in the butterfat. Butterfat or butter oil crystallization is initiated in a tempering unit (40), and the tempered product is deposited on a moving belt (24) which passes through a cooling tunnel (26) to cool ant crystallize the fats to produce a dried butter-based flake product.

Title: Angular position encoder
Inventor: DAMES ANDREW NICHOLAS
IPC: G01D5/20
Filed: 1994-05-03
Granted: 2004-01-20
Abstract: In an apparatus for indicating the angular position of a rotatable member, a drive coil (51) is provided with its axis corresponding to the axis of rotation of the rotatable member. A coil (65) is wound around the rotatable member, and a capacitor (66) is provided in the coil (65) to form an LC resonant circuit. The coil (65) on the rotatable member is wound so that application of an alternating magnetic field to the drive coil (51) induces a resonance in the LC circuit which is constant for all angular positions of the rotatable member. Pick-up coils (53, 55) ace provided such that the planes of these coils and the drive coil (51) are orthogonal. The resonance of the LC circuit produces signals in the output coils (53, 55) which depend upon the angular position of the rotatable member. The signals may be processed to determine that angular position, and the processing is simplified with this arrangement of output coils since the signals produced therein are quadrature signals.
