Patent CA-2385579-C (CA)
Inventor: HWANG KEVIN
IPC: H04B1/707
Filed: 2000-09-08
Granted: 2009-01-27
Abstract: Method and system for carrier recovery and estimation of Doppler shift from a signal source that is moving relative to a signal receiver. A pure carrier preamble for the received signal is processed through each of two stages of a linear predictor to obtain a successively more accurate estimation of a Doppler frequency offset for the carrier. The received signal is downconverted by each stage estimation of the Doppler frequency offset, and the downconverted signal is processed through a decision feedback phase locked loop to provide a signal in which substantially all of the Doppler offset and/or phase angle are identified and removed. The system has low complexity, is fast, and is accurate to within an estimated few tens of Hertz and will work with signals having relatively low signal-to-noise ratios. The invention is useful for receipt of signals from satellites in low earth orbits (LEOs) and other non-geosynchronous orbits, and wherever a transmitter and receiver are moving relative to each other.

Title: Self-sharpening runner
Inventor: LACHANCE GHISLAIN
IPC: A63C5/048
Filed: 2002-06-21
Granted: 2005-01-04
Abstract: A rectangular, self-sharpening runner for a snowmobile ski: it includes a central rectangular blade inserted in the middle of a support, also rectangular and thin. The hardness of the support is less than that of the central carbide runner, which can slide on a hard surface like an asphalt road, where it digs a deep groove to provide traction and adherence to turn on ice and to protect the support against wear when sliding on an asphalted or frozen gravel or abrasive road. The support wears when it runs on frozen gravel-mixed snow-covered roads, but the carbide runner provides a certain protection. There is always a wear difference relating to the difference in hardness and height between the runner and the support, along the whole depth of the runner, thus also making it self-sharpening until the carbide (30) is completely worn away.

Abstract: A fastener including a body and a locking pin is disclosed, The fastener body includes an apertured base and conjoined flexible arms extending from the base and defining a passage therebetween. The locking pin is arranged for movement relative to the fastener body along a predetermined path of travel and within the aperture and the passage defined by the flexible arms. The locking pin has a predriven position and an extended driven position. A resilient lock is provided in conjunction with the fastener body and resiliently extends into the predetermined path of travel of the pin, when said locking or drive pin is in the predriven position, thereby inhibiting movement of said locking pin toward said driven position. The lock remains in position to inhibit inadvertent linear shifting of the driving pin until the flexible arms are inserted through an opening in an article with which the fastener is arranged in operable association. When the flexible arms of the fastener are passed through the opening in the article, the lock is automatically deflected and removed from the path of travel of and permits the locking pin to be moved toward the driven position.

Abstract: A work-assembling auxiliary device for carrying out the matching of phases in the spline-coupling of a main shaft Sm of a transmission T to a crankshaft Sc of an engine E includes an output shaft 40 radially movably connected through an Oldham coupling 41 to an input shaft 30 connected to and rotated by a drive source. A chamfer 61a is provided at a tip end of a socket 61 mounted on the output shaft 40, and in inserting the socket 61 into a socket hole h in a crank pulley Pc, the output shaft 40 is smoothly aligned with the crankshaft Sc by the action of the chamfer 61a. Further, when the output shaft 40 is reciprocally rotated, the phases of the socket 61 and the socket hole h are smoothly matched with each other, whereby the engagement of the socket 61 and the socket hole h is achieved.      Thus, even if a somewhat deviation exists between an axis of the crankshaft Sc of the engine E and an axis of the output shaft 40 of the work-assembling auxiliary device, the socket 61 of the output shaft 40 can be reliably engaged into the socket hole h in the crankshaft Sc.

Title: Three-point hitch having flotation
Inventor: SCHLESSER WALTER MARK
IPC: A01B59/06
Filed: 2004-01-14
Granted: 2007-08-07
Abstract: A three-point hitch suitable for operation with wide implements is constructed by substituting a pair of flotation actuators for the usual drop links that are normally coupled between a pair of rocker arms and a pair of lower draft links. These drop links are coupled to a hydraulic circuit including, according to one embodiment, individual accumulators for each flotation actuator, and according to a second embodiment, both actuators are coupled to a single accumulator. The accumulator(s) act to cause a pre-selected lifting force to be exerted by the flotation actuators so that a predetermined amount of the weight of an implement mounted to the draft links is counterbalanced, leaving a desired ground pressure being exerted by the implement during operation. When using individual accumulators, a side- to- side weight balance can be achieved since different accumulator settings may be used.
