Patent CA-2218528-A1 (CA)
Title: Difference gel electrophoresis using matched multiple dyes
Inventor: WAGGONER ALAN
IPC: G01N33/68
Filed: 1996-04-19
Abstract: A process and a kit are provided for detecting differences in two or more samples of protein. Protein extracts are prepared, for example, from each of a different group of cell samples (1, 2) to be compared. Each protein extract is labeled with a different one of a luminescent dye from a matched set of dyes.  The matched dyes have generally the same ionic and pH characteristics but emit light at different wavelengths to exhibit a different color uponluminescence detection. The labeled protein extracts are mixed together and electrophoresed together. The gel (4) is observed to detect proteins unique to one sample or present in a greater ratio in one sample than in the other. Those unique or excess proteins will fluoresce the color of one of the dyes used. Proteins common to each sample migrate together and fluoresce the same.

Title: Cam and roller overcenter handle mechanism
Inventor: BROCKMEYER DAVID J
IPC: B64C13/04
Filed: 1997-11-17
Abstract: An overcenter mechanism (10) includes a housing (12) and a first shaft (14) mounted on the housing. The first shaft has a first axis (34). A second shaft (20) is mounted on the housing and the second shaft has a second axis (41) that parallels the first axis. A lever (16) is attached to the first shaft, and the lever pivots about the first axis in response to a force (F op) applied to the lever. A cam (18) is attached to the first shaft, and the cam pivots about the first axis. The cam has a cam surface including a first surface portion (58) and a second surface portion (60). The first and second surface portions form a cusp (62) therebetween. A cam follower (21) has a cam follower surface, and the cam follower pivots about the second axis. A  biasing member (26) urges the cam follower surface against the cam surface in pressure contact. The cam follower and the pressure contact cooperate with the cam to generate torque (~holler) on the cam until the cam follower surface contacts the cusp. The pressure contact creates an instability about the cusp when the cusp contacts the cam follower surface, and the torque pivots the cam so the cusp and the cam follower move away from each other.

Patent CA-2227478-A1 (CA)
Inventor: H GE HARALD
IPC: H04B3/20
Filed: 1998-01-20
Abstract: In an echo suppressor and a method for the operation thereof in a speech input system, particularly suited for use in speech input systems having extremely long echo paths (approximately 50 ms), an input request of the speech recognition system as well as the incoming speech signal (which has been corrupted by the input request) are fast-Fourier transformed, and the transformed signals are divided into a number of sub-bands in order to estimate corresponding sub-band echo signals. This occurs with individual adaptive filter stages that utilize the NLMS algorithm. Due to the division into sub-bands and a reduction of the number of these sub-bands, the calculating outlay is minimized and the sampling rate can be reduced. The calculating procedure in the estimating of the echo signal part is thus reduced. After estimating the echo signal for the individual sub-bands, the original signal is restored as a superimposition of the individual echo signal components, and the echo signal restored in this way is subtracted from the corrupted speech signal, so that only a pure speech signal is supplied to the feature extraction stage of the speech recognition system.

Title: Diagnostic system for a cooking appliance
Inventor: BERNARD G KOETHER
IPC: H05B1/02
Filed: 1996-10-25
Abstract: The diagnostic system (120) of the present invention monitors and accumulates the thermal signatures or characteristics during at least one operational mode of the cooking appliance (105). These thermal signatures or characteristics are collected - through the same temperature sensor (115) used to regulate the temperature of the cooking appliance (105) - and then stored in, for example, a look-up table. Advantageously, this may be accomplished without the need of special sensors or interface boards. The thermal signatures or characteristics may include first order or higher order temperature gradients, as well as temperature profiles. The stored thermal signatures provide a baseline from which the diagnostic system can detect and identify whether the cooking appliance is working under normal operating conditions.

The invention integrates into a state-lattice (figure 34) computational model: a polymorphic strong type system; visibility-limiting domains; first-order assertions; and logic for providing a program correctness. This invention includes special hardware means (figure 24) for elimination of cache coherency among other things, necessary to construct state-lattices (figure 6) concurrently. The model of computation for the DANCE language consisting of four, interrelated, logical systems describing state-lattices (figure 6), types, domains (figure 42) and assertions. A fifth logical system (BPL) interrelates the other four systems allowing proofs of program correctness. The method of the present invention teaches programs as temporal formulas satisfied by lattices of states (figure 6) corresponding to correct execution. State-lattices (figure 6) that are short and bushy allow application of many processors simultaneously, thus reducing execution time.

Abstract: Dans la présente méthode et appareil de traitement d'un signal vibro-acoustique émis par un système de commutation haute-tension, le signal vibro-acoustique est converti en un signal numérique. Le signal numérique est redressé et le signal redressé résultant est appliqué à un filtre convolutionnel avec fenêtre spectrale pour produire un signal lissé. Le signal lissé est décimé pour produire un signal décimé représentant une enveloppe du signal vibro-acoustique. Un réalignement temporel du signal décimé est effectué par rapport à une signature de référence pour produire un signal réaligné. Les valeurs de déviation temporelles génèrent une alarme s'ils dépasse un seuil limite. Le signal réaligné est ajouté comme facteur de moyennes produisant une signature de référence et une signature actualisée. Des variances du signal réaligné sont calculées par rapport aux signatures de référence et actualisée. Le signal réaligné est comparé avec les signatures actualisée et de référence pour déceler un changement de comportement graduel ou un défaut subit en tenant compte des variances.
