Patent CA-2274493-A1 (CA)
Inventor: KIRIHARA JULIE A
IPC: A01H5/10
Filed: 1997-12-09
Abstract: The invention provides genetically engineered, preselected DNA sequences and methods of using them to alter the nutritional content of plant seed. Methods of the invention are directed to increasing the weight percent of at least one amino acid essential to the diet of animals, or increasing the starch content of a plant. One such method involves stably transforming a cell of a plant with a preselected DNA sequence encoding a RNA molecule substantially identical or complementary to a messenger RNA (mRNA) encoding a plant seed storage protein, preferably a seed storage protein which is deficient in at least one amino acid essential to the diet of animals. An alternative method employs stably transforming cells with at least two preselected DNA sequences, one of which encodes an RNA molecule substantially identical or complementary to a messenger RNA (mRNA) encoding a plant seed storage protein, and the other preselected DNA molecule which encodes a preselected polypeptide. The transformed cells are used to generate fertile transgenic plants and seeds.  Transgenic seeds are characterized by expression of the preselected DNA  sequence which results in a substantial inhibition of production of a seed storage protein deficient in at least one amino acid essential to the diet of animals and/or an increase in the weight percent of an amino acid essential to the diet of animals.

Title: Water-modifiable flushable polyolefin-containing film
Inventor: WANG JAMES HONGXUE
IPC: C08F283/06
Filed: 1997-12-19
Abstract: A water-modifiable polyolefin-containing film having greater than about 55 weight percent of a polyolefin and less than about 45 weight percent of poly(ethylene oxide). Desirably, the polyolefin can be modified by grafting onto the polyolefin from about 0.1 weight percent to about 30 weight percent of a monomer selected from 2-hydroxyethyl methacrylate or polyethylene glycol ethyl ether methacrylate. More desirably, the polyolefin and poly(ethylene oxide) have grafted thereto a total of from about 0.1 weight percent to about 30 weight percent of the monomer. The polyolefin-containing film, when immersed in water for about 30 seconds, will have a loss of a least 10 % in two or more of the tensile properties: percent strain-to-break, peak stress, energy-to-break and modulus when compared to the dry or pre-immersion values.

Inventor: BEZKOROW ANDREW J
IPC: B65H7/12
Filed: 1999-09-14
Abstract: A double blank detector apparatus and method of operation determines the condition of when one blank, no blanks or more than two blanks are about to be fed into a press. An indicator bar advances relative to the number of blank sheets of material being detected and interrupts an infra-red light beam when only blank of material has been detected. Under this preferred condition, a signal is produced which allows a press located adjacent to the double blank detector to continue its stamping operation. Alternatively, if either a no blank or a double blank condition is sensed, then the indicator bar advances accordingly, thus not interrupting the infra-red light beam. During this condition, a signal is produced indicative of the situation thus notifying the operator that there is a problem and stopping the press from cycling.

Filed: 1998-07-17
Abstract: A dual-rate drive coupling (20, 120) for use in transmitting drive torque between drive and driven members. The first torque rate is near zero for noload and near no-load conditions. A pair of flexible elastomeric arms (24, 26, 124, 126) which are preferably bonded to the inner member (22, 122) are received in recessed portions (44, 46, etc.) in the outer member (40, 140) and provide the coupling with this first very low torque rate. When higher torque loading produces a relative rotation between the outer member (40, 140) and the inner member (22, 122) of at least about 15~, a pair of snubbing arms (28, 30, 128, 130) of the inner member (22, 122) interact with surfaces of openings (48, 50, etc.) of the outer member (40, 140). The contact surfaces of these second snubbing arms (28, 30, 128, 130) are coated with an elastomer to snub all contact between the inner member (22) and the outer member (40) to inhibit vibration induced rattling. In a second preferred embodiment, the elastomeric arms (24, 26, 124, 126) are curved in opposite directions and the second pair of arms (28, 30, 128, 130) are skewed away from drive engagement such that a relative rotation of at least about 25~ is needeed to bring the second pair of arms (28, 30, 128, 130) into driving engagement with the outer member (40, 140).

Inventor: YELDENER SUAT
IPC: G10L25/90
Filed: 1998-11-16
Abstract: The present invention provides a method of pitch estimation which utilizes perception based analysis by synthesis for improved pitch estimation over a variety of input speech conditions. Initially, pitch candidates are generated corresponding to a plurality of sub-ranges within a pitch search range (item 2). Then a residual spectrum is determined for a segment of speech (item 4) and a reference speech signal is generated from the residual spectrum using sinusoidal synthesis (item 8) and linear predictive coding (LPC) synthesis (item 9). A synthetic speech signal is generated for each of the pitch candidates using sinusoidal (item 12) and LPC synthesis (item 13). Finally, the synthetic speech signal for each pitch candidate is compared with the reference residual signal (item 14) to determine an optimal pitch estimate based on a pitch period of a synthetic speech signal that provides a maximum signal to noise ratio.

Title: Method of making a shaped absorbent interlabial device
Inventor: MCFALL RONALD RAY
IPC: A61F13/472
Filed: 1998-11-25
Abstract: A method of making an absorbent device that is worn interlabially by female wearers for catamenial purposes, incontinence protection, or both, is disclosed. The method involves at least partially enclosing a continuous length of absorbent material in a cover material. The cover material is positioned so that it lies on opposite sides of the length of absorbent material. The absorbent material is then optionally shaped so that along its length there are regions of greater and lesser thickness on alternating sides of the longitudinal axis of the absorbent material. In one embodiment, the shaping is accomplished by bonding a first portion of the cover material to a second portion of the cover material on the opposite side of the absorbent material so that the bonding penetrates through the absorbent material. A generally transverse direction cut is made across the length of absorbent material which alternates longitudinally across the length of absorbent material to provide the device with shaped ends. The method produces a plurality of interlabial devices having an asymmetrical shape about a longitudinal axis and shaped end with a minimum of waste therebetween.

Inventor: LEIS STEPHEN ELDON
IPC: G01S17/875
Filed: 1998-12-02
Abstract: A system for determining the spatial position and orientation of each of a plurality of bodies. Each one of the bodies has at least three markers in a predetermined, relative geometric relationship. The markers are adapted to emit energy in response to an activation signal and/or to reflect energy impinging ups such passive marker from an activatable energy source. A common energy detector is provided for detecting the energy emitted by the active marker and the energy reflected by the passive marker. A common processor is provided. The processor has a memory. The memory has stored therein the predetermined, relative geometric relation of the markers for each one of the bodies. The processor compares the stored predetermined geometric relation of the markers for each of the bodies with the energy detected by the energy detector to identify the bodies emitting, or reflecting the detected energy. With such an arrangement, a body can be tracked using a very simple sequence of operation in real-time with robust positive marker identification by taking advantage of a simple marker placement methodology. Multiple bodies can thereby be tracked simultaneously.

Abstract: A method of relaying digital video data over a communications medium such as the Internet is provided where accelerated relaying time can be realised. The method involves assembling digital data of one frame representing a scene of a video image plus data of one or more filters and parameters therefor to be applied to the digital data over a plurality of repeated frames of that scene. All that data is relayed to a users personal computer and then an apparent video movie is generated at the personal computer over a plurality of repeated frame images of the one frame by applying the filters thereto. The filters can include PAN ZOOM FADE etc., so that when applied over the plurality of frames each of the same scene, there will be an apparent motion video movie. Many scenes and filters can be employed to enhance the video. In providing a video of real estate, such as details of an apartment, a 2-D floor plan of the apartment can also be relayed so that a viewer of the apparent video can obtain a better understanding of the image being viewed at any given point of time. The 2-D floor plan can have a route-of-path line drawn thereon to further enhance the understanding of the image being viewed. A moving indicator can be displayed over the route-of-path which can be approximately synchronised with the apparent video to give an approximate indication on the route-of-path for the image being viewed at any given point of time.
