Patent CA-2380264-A1 (CA)
Title: Method and apparatus for reducing frame error rate
Inventor: SCHIFF LEONARD N
IPC: H04L1/00
Filed: 2000-07-14
Abstract: A method and apparatus for controlling a signal transmission power. The method of the present invention includes the steps of demodulating a received signal (401) to produce a demodulated signal (407) and distorting the demodulated signal (412) to produce a distorted demodulated signal (413). The demodulated signal (412) can be distorted by, for example, adding noise. A  signal quality measurement, such as signal-to-noise ratio, is then determined (416, 418, 502, 602) based on the distorted demodulated signal rather than the demodulated signal. An adjustment in the transmission power is then requested (420, 506, 508) based on the signal quality measurement of the distorted demodulated signal.

Abstract: L'invention concerne un procédé de traitement d'une étoffe tissée servant à produire une association extensible et consistant à appliquer chaleur et pression sur l'étoffe de manière que les fils à brins multiples, situés sensiblement sur la largeur de l'étoffe, soient forcés de se rapprocher, dotant ainsi l'étoffe d'une extensibilité généralement semi permanente, tout en thermocollant au moins partiellement à cette étoffe une doublure synthétique au moyen d'un agent ou d'une pellicule de liaison extensible. L'étoffe tissée employée dans le procédé de l'invention est généralement à base de matière textile non synthétique, par exemple de la laine ou du coton, ne pouvant généralement être mise en forme de façon permanente uniquement par la chaleur. En revanche, la matière doublante est habituellement une matière synthétique thermoplastique pouvant être thermodurcie, telle qu'une matière textile polyester ou polyamide. Le revêtement ou film thermocollant est, de préférence, un matériau qui en même temps qu'il assure la liaison entre les deux étoffes dote le produit final d'une certaine extensibilité, -c'est pourquoi on préfère utiliser une matière polyuréthanne-, et qui peut être déposé soit sur l'étoffe non synthétique, soit sur la doublure, ou qui peut être une pellicule interposée entre ces deux étoffes.

Title: Remote adjustment mechanism for a combine harvester cleaning element
Inventor: NELSON JEFF ARTHUR
IPC: A01F12/44
Filed: 2002-04-19
Abstract: A remote adjustment mechanism for the louvered cleaning elements of a combine harvester has a linearly movable output member directly fastened to the adjusting bar of each element. The actuator is driven by an electric motor. Calibration and feedback of the louver opening is provided by a pair of non-contact sensors sealed in the actuator housing. A first sensor sends a signal to a microprocessor controller when the output member is in a home position corresponding to a known louver opening. The second sensor sends a signal to the microprocessor that is responsive to movement of the output member. By tracking the movement of the output member from the home position, the current position of the output member is known from which the louver opening is determined based on the louver geometry.

Inventor: GILBERT GENE
IPC: F04B27/00
Filed: 2000-08-26
Abstract: A cylinder is divided into two chambers by a wall to receive a pair of pistons. This reduces the stroke length and correspondingly reduces the line ar speed of the piston. This leads to a reduced PV factor associated with degradation and wear of the piston rings. Moreover, the multi-cylinder arrangement provides the same performance in an oil-free compressor asesmbly  without appreciably expanding dimensional constraints relative to known systems.
