Inventor: COLLIER R JOHN
IPC: C12Q1/68
Filed: 1996-06-03
Abstract: L'invention porte sur une méthode de sélection génétique basée sur la cytotoxicité (TOXSEL) et son matériel d'expérimentation destinés à l'identification et la sélection positive de molécules ou de mutations à même d'interrompre une interaction inter-protéique spécifique. L'invention permet la sélection positive de molécules qui interrompent les interactions inter-protéiques spécifiques grâce à la présence dans le système TOXSEL d'un gène reporter de toxine. Une interaction interprotéique interrompue empêche l'expression du gène reporter de toxine et, par conséquent, permet d'assurer la survie de la cellule hôte. La technologie TOXSEL permet le criblage à grande échelle de médicaments ou de petites molécules à même d'interrompre des interactions inter-protéiques spécifiques indispensables aux processus de signalisation cellulaire, de carcinogenèse, etc. La sélection positive de molécules ou de mutations à même de faire obstacle aux interactions inter-protéiques spécifiques permet d'identifier des restes ou des motifs structuraux d'acides aminés et de concevoir des médicaments à des fins thérapeutiques ou diagnostiques.

Filed: 1996-05-31
Abstract: A hearing aid or audio communication system includes an earpiece (10) that can be hidden in the ear canal, and which communicates wirelessly with a remote processor unit, or RPU (16), that enhances audio signals and can be concealed under clothing. Sounds from the environnment are picked up by a microphone (12) in the earpiece and sent with other information over a two-way wireless link (17) to the RPU (16). The wireless link (17) uses microwaves for component miniaturization. Furthermore, use of radar technology to implement the wireless link (17), with an RPU (16) interrogator and earpiece (10) transponder, reduces earpiece size and power, as no microwave oscillator is needed in the earpiece (10). Optional secondary wireless link circuitry (19) can be used between the RPU (16) and a cellular telephone system or other sources of information. Electronic voice recognition and response can control system operation.

Title: Methods and apparatus for efficient quantization of gain parameters in glpas speech coders
Inventor: FOODEEI MAJID
IPC: G10L19/04
Filed: 1998-05-29
Abstract: In methods and apparatus for encoding a gain parameter in a generalized linear predictive analysis-by-synthesis (GLPAS) coder, a subframe gain parameter is determined for each of a plurality of successive subframes of a frame, and a quantized frame gain parameter is determined for each frame using a delayed decision quantizer operating on the subframe gain parameters. The subframe gain parameters may be treated as components of a gain vector and the gain vector may be vector quantized to determine the quantized frame gain parameter. Encoder parameters are efficiently aligned with decoder paramters to ensure proper end-to-end operation. Alternatively, tree quantization or trellis quantization may be applied to the subframe gain parameters to determine the quantized frame gain parameter. The methods and apparatus are particularly applicable to low bit rate speech coding.

Title: Method and device for driving a turn-off thyristor
Inventor: GRUENING HORST
IPC: H03K17/04
Filed: 1998-07-21
Abstract: A method for turning a GTO on and off and a corresponding driving circuit are specified. The turn-on current and the holding current are generated from voltage pulses which are converted into currents with the aid of an electric energy store. In terms of circuitry, it is particularly advantageous when the required voltage pulses are drawn from the same energy source, or the same energy store, as the pulse required to generate the turn-off current. The holding current is preferably generated by repeating voltage pulses.      The repetition frequency of said voltage pulses can then be increased or reduced as required. The frequency is reduced, in particular, when the gate-cathode voltage becomes negative, and is increased again when the voltage is positive again.

Patent CA-2251495-A1 (CA)
Inventor: WESEEN ROGER D
IPC: B60J3/02
Filed: 1998-11-02
Abstract: The inventive idea which the new device embodies and the way in which resort to it overcomes the difficulties and inconveniences of previous practices is as follows:      Problem : While driving a vehicle and utilizing the sunvisor for protection from the sun,a person of smaller stature is afforded little or no relief from the sun's rays during the early morning , late afternoon or in Spring and Fall due to the angle of the sun.      This problem exists because the sunvisor does not fold down far enough for adequate protection.      Solution: I have found that this disadvantage may be overcome by utilizing the extention visor for additional sun or glare protection.      The extention visor is installed on both the driver's side and the front sear passenger side position. The extention visor may then be utilized by the driver or the front seat passenger or both.The sunvisor and the extention visor are then adjusted to one's comfort level without impairing thier vision.      Abstract:The extention visor is mounted on the back of the regular sunvisor. To employ the extention visor, begin by swivelling the sunvisor to its down postion.Place your hand in the middle top portion of the Plexiglas extention visor and with a little outward pressure , separate the velcro fastener that holds the extention visor in the closed position. Pivot the extention visor on its hinges to the full down vertical position. As you swivel the sunvisor on its horizontal arm toward the windshield, the extention visor follows and gradually pivots on its acrylic hinges to maintain its vertical position. Continue to rotate the sunvisor until the desired sun/glare protection is achieved. To close the extention visor simply reverse the procedure until the volcro fastener is locked in position.      Description of Drawings: Plate# 1 Depicts a randomly acquired sunvisor from the multitude of all the shapes and sizes that are available from any auto parts dealer. This particular sunvisor has a coverless vanity mirror while others have covered vanity mirrors and still others have no vanity mirror at all and have a plain back. The dimensions of this sunvisor are the actual measurements. Photographs are enclosed.   Plate# 2 Shows the extention visor mounted and laying open.      Plate# 3 Shows the same extention visor mounted and laying closed.      The extention visor may be modified to fit any shape and size of sunvisor.      The embodiments of the invention in which an exclusive property or privilege is claimed is defined as follows: [1] On land: on such vehicles as cars,trucks, vans, 4x4s, station wagons, sports utility vehicles and tractor trailers.      On the farm: on cab over tractors and self-propelled combines.      Road Building: road graders, caterpillars and euclids. [2] In the Air: airplanes, helicopters and spacecraft. [3] On the water: boats with cabins,ships, cabin cruisers and boats equipped with windshields.
