Patent CA-2269185-C (CA)
Title: Parking brake lock-in key switch system for vehicle air brake system
Inventor: DOUGLAS ROBERT L
IPC: B60R25/08
Filed: 1999-04-15
Granted: 2006-11-21
Abstract: A parking brake lock-in key switch system for a truck or bus brake system. The system has two parking brake lock-in valves. One parking brake lock-in valve is installed in the air line piping between the primary air tank and the push pull double check valve and the second parking brake lock-in valve is in the air line piping between the secondary air tank and the push pull double check valve. The parking brake lock-in valves are air operated valves which when closed will lock in actuated parking brakes. The parking brake lock-in valves are operated by a solenoid operated pilot valve which provides air from an air supply to close the lock-in valves when the ignition key is moved to the 'off' position. An actuated parking brake will be locked in because new air from the respective tanks will be prevented from flowing to the push pull double check valve and hence the brake chambers. The parking brake lock-in valve does not vent off downstream piping when it closes. Should the ignition key be positioned to the 'off' position with the vehicle in motion and the parking brake actuator is not engaged in the park position, air will be locked in the air line piping between the parking brake lock-in valves and the individual brake chambers including the piping in which the push pull double check valve is installed. This locked in air will prevent the brake chambers from locking the wheels, hence preventing inadvertent engagement of the parking brakes.

Abstract: A synthetic structure is used to simultaneously provide food, shelter and reproductive support for many aquatic species. Synthetic seagrass may be produced in the form of flexible mats (10) with a plurality of ribbons (12). The lower ends of the ribbons (12) are anchored to the benthos (16). The other ends of the ribbons (12) are buoyant ly supported in the photic zone (18). The ribbons (12) may be economically produced in plural coextensive layers, with one layer providing buoyancy and the other layer being structured to enhance biological growth. The system may be tailored for use in desired application s by selecting the surface area structure, ribbon spacing and density, and other parameters.

Title: Rotary seal with relief angle for controlled tipping
Inventor: BAEHL JEFF
IPC: F16J15/46
Filed: 1999-10-29
Granted: 2010-05-18
Abstract: A sealing device for sealing the gap between two relatively moving members is provided with a pivot point on its cross- sectional perimeter. As pressure against the seal increases, the seal rotates about the pivot point, resulting in an increased sealing surface area on the seal. Additionally, a recess is provided on the cross sectional perimeter, advantageously offering a more frictionless sealing relationship between the seal and the moving member. Further, a recess is provided on outer portion of the cross sectional perimeter on a surface of the seal that would contact an energizer ring, the recess eliminating a dynamic interface between the energizer ring and the seal.

Title: Materials handling vehicle having an expanded operator's compartment
Inventor: TEBBE PATRICK A
IPC: B66F9/075
Filed: 1998-08-26
Granted: 2006-10-24
Abstract: The motor compartment (400) of a fork lift truck (10) is modified so that the operator's feet extend into the space normally required by the motor compartment. A motor support structure (430) is installed between the traction motor (410) and the gear box (440) which is connected to the steerable, powered wheel (25). The motor support structure occupies a smaller space than the traction motor itself, thus increasing the space available to the operator's compartment (70), at least in a limited vertical location adjacent to the support. With the traction motor out of the way, sufficient space for elevated pedals (130, 135, 140) is provided, thus providing the operator (200) ample space to operate the truck while seated. A battery compartment (20) and hydraulic system (500, 505, 510, 515) of the truck are positioned adjacent to one another and ahead of the operator's compartment/motor compartment. In this way, the battery compartment and hydraulic system are positioned such that they are clear of the operator's compartment.

Abstract: A pixel data outputting circuit outputs center and peripheral pixel data from a video signal. A difference calculation circuit calculates differences of the peripheral pixel data from the center pixel data. A correlation pixel data detecting circuit detects a portion of the peripheral data showing high correlation according to the differences and a threshold value. A counter counts the portion of the peripheral data showing high correlation.      A selecting circuit responsive to the correlation pixel data detecting circuit selectively outputs a portion of the differences of the portion of the peripheral data. A summing circuit obtains a sum of the portion of the differences in accordance with the counting result. A dividing coefficient generating circuit generates a dividing coefficient of 2 n according to the counting result.      A dividing circuit divides the sum with the dividing coefficient. An adding circuit adds the dividing result to the center pixel data to generate an output video signal.      A weighting circuit weights each of the portion of differences according to the predetermined priority, wherein the summing circuit obtains the sum from the weighted differences. The corresponding method and the corresponding recording medium storing the method are also disclosed.

Title: Digital variable symbol rate modulation
Inventor: KNUTSON PAUL GOTHARD
IPC: H04W56/00
Filed: 1999-10-21
Granted: 2009-11-24
Abstract: A wireless telephone system having a plurality of wireless handsets and a base unit, the base unit having a base transceiver. Each handset has a handset transceiver for establishing a wireless link over a shared channel with the base unit via the base transceiver, wherein the base transceiver transmits to a handset transceiver a first signal representing successive symbols at a first symbol rate. The handset transceiver has a receiver and a transmitter, and a local clock signal generator that provides clock signals at a local clock frequency. The receiver receives samples representing the first signal, and generates symbol error measurements used to cause a receiver interpolator to produce, in response to the received samples, samples taken at times synchronized to the successive symbols of the first signal. The handset transmitter transmits to the base transceiver a second signal representing successive symbols at a second symbol rate by modifying the second symbol rate in accordance with the symbol error measurements so that the second symbol rate is substantially identical to the first symbol rate.

Granted: 2006-10-17
Abstract: A technique for time domain avoidance of communications link interference sources characterized by intermittent, periodic short bursts of energy. A  transmitting source can be assigned two time slots within a time domain multiple access data frame over which each data packet can be transmitted. The time slots are separated by a duration greater than that of an interference burst, such that an interference burst does not affect both time slots in any given frame. Therefore, the data packet can be received on at least one of the two assigned time slots. Transmitter power consumption can be reduced by calculating the timing of the periodic interference bursts, and only transmitting a data packet on one of the two assigned time slots that will not coincide with an interference burst in each frame. Communications link capacity can be improved during the presence of interference by synchronizing the data frame to the timing of the interference bursts. The bursts then occupy fixed time slots in each data frame, enabling standard single time slot transmissions for the remaining communications channels in the data frame.
