Patent CA-2114214-A1 (CA)
Inventor: GOLDSTEIN YURI
IPC: H04L27/00
Filed: 1992-07-17
Abstract: The preferred method comprises measuring the signal/noise ratio and intermodulation distortion (IMD) relating to signals being transmitted over a channel (25) and adjusting the transmitting power of the,transmitting modem (209) below a maximum permissable power in response to the measurements in order to reduce the error rate of the data transmission, the error rate being a function of both the signal/noise ratio and he IMD. Theoretically, the power can be adjusted to an optimal level, as the decrease in power increases he error rate due to signal/noise ratio according to a first function, but decreases the error rate due to IMD according to a second function. A first preferred manner of determining the final power level to be utilized is to calibrate a modem according to the techniques (e.g., Treillis precoding, etc.) it utilizes, and to utilize a look-up table for that modem to identify the desired power level based on the measured signal/noise ratio and the measured IMD. A second preferred manner is to decrease the signal power according to a formula which is a function of the third harmonic IMD.

Filed: 1992-02-20
Abstract: The present invention provides solid state power controller governance circuitry which includes a power level select circuit (150, 152, 154 155, 156), a power level transition circuit (280), a controlled power limiting circuit (300, 320, 340, 380, 202), and a power level transition reset circuit (280, 390). The circuits together provide an analog voltage or resistance signal for input to a standard power controller device that allows not only for the efficient control of the power level in the power level in the powered device, but additionally provides for controlled power limiting to the powered device when changes in the function of the powered device are initiated or when other conditions warrant rapid power limiting to the device. The circuits also provide means whereby the powered device may be appropriately re-powered from a zero state after controlled power limiting has occured. Together the circuits of the present invention provide a means whereby powered devices may be efficiently, smoothly, and safely operated by standard power motor controller circuits.
Patent CA-2120207-A1 (CA)
Title: Tracula
Inventor: MILBURN CHRISTOPHER L
IPC: E01H4/02
Filed: 1994-06-17
Abstract: On a T-Bar ski lift track as well as on cross country ski trails it is often necessary to groom the icy conditions resulting from frequent use and weather conditions. This invention incorporates the use of a drive roller which is coupled to a tiller roller by use of a chain and sprocket assembly or a belt and pulley assembly. These rollers are housed under a shroud constructed from aluminium. The unit described has a yoke and seat attached to it which is then hooked onto the existing T-Bar by means of a quick release safety belt. The operator rides behind the T-Bar seated on the cross member of the yoke. As the T-Bar progresses up the hill the drive roller rolls along causing the tiller roller to spin and chew up the icy surface. As in use on cross country ski trails the unit will be towed behind a snow-mobile causing the same results.

Title: Fixation de planche a neige avec plaque compensatrice
Inventor: FOURNIER LOUIS
IPC: A63C9/02
Filed: 1994-05-17
Abstract: Une fixation pour planche à neige comprenant une base destinée à contenir le pied, un coussinet de cou-de-pied destiné a couvrir le haut du pied, un support arrière articulé destiné à couvrir l'arrière du talon et de la jambe. Le coussinet de cou-de-pied est relié a la base par des câbles de tension passant dans les cotés de la base et étant finalement attachés sur le support arrière. Le support arrière est maintenu à la verticale par un levier a ressort. Lorsque le levier est tiré, le support arrière peut se rabattre vers l'arrière, dégageant l'espace arrière et relâchant la tension dans les câbles, ce qui permet un accès facile du pied. Ramener le support arrière à la verticale a pour effet de rétablir la tension des câbles pour maintenir le pied fermement en place grâce aux effets combinés du support arrière et du coussinet de cou-de-pied. Lorsqu'un pied n'est pas dans la fixation, le support arrière peut se replier sur la base afin d'occuper moins d'espace de rangement.
