Patent CA-2146641-C (CA)
Inventor: LARSON DONALD G
IPC: H01S3/0977
Filed: 1993-10-05
Granted: 2003-04-29
Abstract: An anode (14) and a cathode (16) in a laser (10) are spaced in a first direction. A voltage difference be-tween these members produces an electrical discharge which ionizes gases (18) in the laser (10) to react chemi-cally and produce coherent radiation. First and second tubes (22) made from a dielectric material are spaced in the laser (10) in a second direction transverse (preferably perpendicular) to the first direction. The anode (14), the cathode (16) and the tubes (22) extend through the laser (10) in a direction transverse (preferably perpendicular) to the first and second directions. The tubes (22) are preferably at least a 99.9 % pure polycrystalline alumi-num oxide ceramic with traces of other metallic elements than aluminum. Bushings (24) made from a material homogenous (preferably identical) to the tube material are integral with the tube (22) near the opposite tube ends. First electrical conductors (30) extend through the tubes (22). Second electrical conductors (32) (preferably resilient) contact (preferably line contact) the external tube surfaces to define capacitors with the first conduc-tors (30) and the tube material. Positioning members (36) movably engage the tube external surfaces near the tube ends in co-operation with the resilient members es-tablishing three (3) - line contacts with the tubes (22) for positioning the tubes (22) precisely in the cavity (1). When a voltage pulse is applied between the first conductor (30) inside each tube (22) and the conductors (32) on such tube (22), the resultant cor-ona discharge from the external tube surface produces ultraviolet light which pre-ionizes the gases (18) in the cavity (12). This fa-cilitates the ionization of the gases (18) in the cavity (12) when an anode (14)-cathode (16) electrical discharge is produced.

Title: Method and apparatus for creating a composite waveform
Inventor: SCHAFFNER TERRY MICHAEL
IPC: H04B1/707
Filed: 1994-10-31
Granted: 1996-12-24
Abstract: A method and apparatus is provided for creating a composite waveform. This composite waveform is created by coding a plurality of input digital information signals (201). Subsequently, the plurality of coded input digital information signals (231, 235, 237) are communicated over a communication medium (103) to a digital combiner 9105). The digital combiner (105) combines the plurality of coded input digital information signals. Finally, the digitally combined information signal is spectrally shaped to form a composite waveform (107). These composite waveform creation principals may be applied to digitally encoded voice subbands in a subband coding system as well as channel information in a direct sequence code division multiple access (DS-CDMA) communication system transmitter.

IPC: G06K9/66
Filed: 1996-03-14
Granted: 2000-04-11
Abstract: A technique for automatically training a set of character templates using unsegmented training samples uses as input a two-dimensional (2D) image of characters, called glyphs, as the source of training samples, a transcription associated with the 2D image as a source of labels for the glyph samples, and an explicit, formal 2D image source model that models as a grammar the structural and functional features of a set of 2D images that may be used as the source of training data. The input transcription may be a literaltranscription associated with the 2D input image, or it may be nonliteral, for example containing logical structure tags for document formatting, such as found in markup languages. The technique uses spatial positioning information about the 2D image modeled by the 2D image source model and uses labels in the transcription to determine labeled glyph positions in the 2D image that identify locations of glyph samples. The character templates are produced using the input 2D image and the labeled glyph positions without assigning pixels to glyph samples prior to training. In one implementation, the 2D image source model is a regular grammar having the form of a finite state transition network, and the transcription is also represented as a finite state network. The two networks are merged to produce a transcription-image network, which is used to decode the input 2D image to produce labeled glyph positions that identify training data samples in the 2D image. In one implementation of the template construction process, a pixel scoring technique is used to produce character templates contemporaneously from blocks of training data samples aligned at glyph positions.

Title: Data protocol for a music chip
Inventor: GREWE ANTHONY JAMES
IPC: G10L19/00
Filed: 1996-05-21
Granted: 2000-03-21
Abstract: A protocol for labeling various types of data contained in a music chip. The protocol includes a hierarchical arrangement of headers for storing information about selections on the chip and the method in which they were coded in the memory of the chip. A global header located at the very start of memory will specify information needed to successfully decode the content of the music chip. This will include, for example, the necessary bit rate, as well as information pertaining to a specific PAC (Perceptual Audio Coding) algorithm employed in recording audio on the chip. In addition to the global header, each chip will have a section of memory allocated to a table of contents. The table of contents will include information on play times, song titles, music category and artist. Individual track selections will be listed as part of the table of contents by individual headers. The individual header contains a music category to which a track belongs, for example, classical, jazz, country, rock, etc., the artist, and information for addressing each track selection. Information from the headers is self-registered or automatically downloaded when a chip is loaded into a player/juke box device. The concept of self-registering general information included within the headers allows a user to select by type of music, artist, etc. for music selections made over a period of time.

Title: Method of and apparatus for molding a hollow fan blade
Inventor: MONROE ROBERT C
IPC: B29C33/00
Filed: 1996-12-18
Granted: 1999-08-24
Abstract: A method of and apparatus for molding hollow items using the resin transfer molding technique in such a manner that the resin is more uniformly distributed about and along the molding region of the mold.   This is accomplished by installing oppositely spaced grooves in the mold and injecting resin directly into these grooves.  Upon such injection, the resin travels along and fills the groove (by taking the path of least resistance) before such resin is squeezed or forced out a minute gap that exists between the molding surfaces and into the molding region of the mold.  As such resin is being forcibly injected into the cloths in the mold, a vent permits any air displaced from the cloths by the resin to be released.  Such resin injection and mold venting occurs until such time that no more air is vented and instead 100% resin  is being discharged from the mold.   Upon this occurrence, further resin injection is curtailed and the resin previously injected is allowed to harden and cure.  A disposable pressure bag distributes the molding pressure created by the injected resin equally within the mold.  Thus, this pressure bag enables a high quality void-free plastic laminate to be made.          A means of pressurizing this bag while maintaining a seal that prevents any loss of resin is also disclosed.

Granted: 2000-01-18
Abstract: An ignition system is provided for an internal combustion engine (67) that operates in two modes. In a first mode, the timing of the spark event is under electronic control. In a second mode, the timing of the spark event is fixed and synchronized to the mechanical rotation of the crankshaft (65) of the engine. Under normal operating conditions, the timing of the spark event is electronically controlled. If the electrical system of the engine malfunctions, the ignition system defaults to the second mode in which ignition timing is mechanically controlled.
