Patent CA-2139268-C (CA)
Title: Sync acquisition and tracking circuit for ds/cdma receiver
Inventor: KAKU TOMOYA
IPC: H04J13/00
Filed: 1994-12-29
Granted: 2000-04-04
Abstract: In a sync acquisition and tracking circuit for a DS/CDMA receiver, phase position signals are sequentially and cyclically selected at a specified rate higher than the rate at which Rayleigh fading occurs. The selected signal is used to control the phase of PN sequences. Correlation is taken between spread pilot signals and the orthogonal PN sequences at a chip rate to produce despread pilot signals, which are integrated to produce a correlation value. A set of accumulators are provided, which are sequentially and cyclically selected at the specified rate. The correlation value is applied to the selected accumulator to produce a total sum of correlation values. The highest total sums are selected from the outputs of all accumulators, and corresponding phase position signals are identified. A set of orthogonal despreading sequences are generated corresponding to the identified phase position signals for application to the receiver.

Patent CA-2152328-C (CA)
Inventor: RAJALA GREGORY JOHN
IPC: B29C65/00
Filed: 1995-06-21
Granted: 2006-08-01
Abstract: This invention pertains to methods and apparatus for use in constructing a garment including a stretched elastic. Specifically, the invention contemplates incorporating stretched elastic into a continuous web, including one or more segments which exert retractive forces in directions counterproductive to the function of either the web, the garment, or both, and nullifying that portion of the stretched elastic which would be counterproductive. The elastics may be cut at appropriate loci. The stretch may be intermittently reduced or eliminated on one or more selected ones of the elastics as the elastics are incorporated into the web. A special coating may be used on the processing rolls to maintain the width dimension of the web at loci disposed after incorporation of elastic stretched across the transverse dimension of the web. Transverse bonds may be formed on the web using a rotary carrying drum, and energy application devices which rotate with the drum, to increase bond forming time.

Title: System and method for establishing communications over a network
Inventor: FOLADARE MARK JEFFREY
IPC: H04M3/42
Filed: 1996-01-02
Granted: 1999-07-13
Abstract: A communication system capable of establishing communication with a mobile party having a Personal Telephone Number. The mobile party uses a two-way pager to transmit a forwarding number to a paging service. The paging service relays the forwarding number to a Customer Routing Point where the number is stored. Whenever a caller initiates a call to the mobile party by dialing the mobile party's Personal Telephone Number, the Customer Routing Point is notified. The Customer Routing Point then cross-references the Personal Telephone Number with the forwarding number and forwards the call to a terminating telephone associated with the forwarding number. In one possible embodiment an adjunct is used in conjunction with the Customer Routing Point to offer call forwarding service on both a call by call basis and a registration basis.

Abstract: An optical code recognition unit (OCRU) for recognizing a predetermined n-bit optical code sequence coded using the Manchester code format, has an n-way splitter (7) having an input and n parallel outputs (7a).  A plurality of gates (9a, 9b, 9c, 9d) are associated with the splitter outputs (7a), respective pairs of splitter outputs leading to each of the gates (9a, 9b, 9c) via a respective optical combiner (8a, 8b, 8c), and any remaining single splitter output leading directly to its gate (9d).  Each of the splitter outputs (7a) is subject to a different delay of m half bit periods, where m = 0 to 2(n-1), the values of m being chosen such that, if a predetermined optical code sequence is applied to the splitter input, the '1's in the outputs of each of the pairs of splitter outputs (7a) reach the associated AND gates (9a, 9b, 9c) and the '1' in any remaining single splitter output (7a) reaches its AND gate (9d) at predetermined times such that all the gates are turned on.

Abstract: Apparatus and methods are shown for controlling a weighing machine in which product is fed into one end a vibratable pan of a vibratory feeder and is discharged from the other end, for example into a weigh bucket. In a first embodiment, the amplitude of vibration of a pan is measured and is compared to adesired amplitude. The measured amplitude is compared to a desired amplitude, and the amplitude of vibration is adjusted by modifying an input signal to a vibrator attached to the pan until the measured amplitude equals the desired amplitude. In a second embodiment, a mechanism is included to stop the loading of product into a pan when a predetermined amount of product has been discharged from a pan into a weigh bucket, and the weight of product in the pan is monitored as additional product is discharged into the weigh bucket. Only a preselected additional weight of product is subsequently discharged into the weigh bucket. A third embodiment involves at least two pans arranged in series, and the weight of product in the downstream pan is determined and monitored. The measured weight is compared to a desired weight of product in the downstream pan, and the amplitude of vibration of the upstream pan is adjusted, as needed, in a closed-loop manner to feed more or less product into the downstream pan to establish and maintain the desired weight in the downstream pan.

Abstract: In a hollow earth auger head assembly a plurality of bit-holding pockets are provided, spaced circumferentially from one another around an open mouth of an auger head, and bits taken selectively from a multiplicity of types of cutting teeth, have a shank portion that seats in any and all of the pockets. A retaining pin extends chordally, off-set from a diameter, through holes in the pocket and into a retaining pin receiver in the bits. In those bits that are intended to rotate in the pocket, the retaining receiver takes the form of an annular channel. In those bits that are not supposed to rotate, the retaining pin extends through a linear passage in or along a flat on the bit shank. In certain embodiments of sockets a chordal plug or weldment defines a space with one flat side against which a tail of the shanks of certain bits designed not to rotate bear.

Title: Apparatus for processing mixed yuv and color palettized video signals
Inventor: BUTLER DONALD S
IPC: H04N5/445
Filed: 1996-06-24
Granted: 2000-04-25
Abstract: Apparatus processes mixed YUV and color palettized video signals, where "Y" of YUV is the luminance signal and "U" and "V" are the color difference signals, B-Y and R-Y respectively, for display on an interlaced NTSC or PAL television receiver by storing first and second fields of one or more sprites in a graphic memory. The sprites are stored as YUV or color palettized data and each sprite is given a priority. A higher priority sprite overwrites pixel data of sprites of a lower priority when sprites overlap. First and second adjacent horizontal lines of pixel data in the first and second fields, respectively, are concurrently stored in respective first and second double buffers of a pixel assembly buffer during each line period. A delay buffer and the first and second double buffers generate first, second, and third adjacent horizontal lines, respectively, of pixel data at the output of the pixel assembly buffer while third and fourth adjacent horizontal lines of pixel data are inputted to the first and second double buffers. A convolving means receives the first, second, and third output signals from the pixel assembly buffer and generates therefrom an output signal providing a weighted average for a central pixel of a predetermined matrix of pixel data for transmission to the television receiver when a sprite is included in a pixel area of the display of the television receiver. A live video signal is transmitted to the display of the television receiver when no sprite is included in a pixel area of the display of the television receiver.
