Patent CA-2254458-A1 (CA)
Inventor: DAVID FREDERICK R
IPC: D03D1/00
Filed: 1998-11-24
Abstract: A webbing for seat belts having a plurality of warp yarns interwoven with a plurality of weft yarns which are inserted through a shed in the warp yarns is provided. The warp yarns include a first group and a second group, with the second group of warp yarns having a higher density across a portion of the width of the shed than the warp yarns of the first group. At least some of the warp yarns in the second group are separated from one another by the warp yarns of the first group. The webbing has two faces and is flexible from a first, generally flat position to a second, flexed position. When the webbing is in the generally flat position, the first and second groups of warp yarns on one fabric face define a generally smooth surface. When the webbing is in the second, flexed position in which a first portion of the one fabric face is separated from a second portion of the one fabric face by a transition area, and the first portion is positioned generally at an angle a of less than 180° from the second portion of the one fabric face, at least a portion of the second group of warp yarns in the transition area protrude at least partially from the generally smooth surface to define a plurality of ribs.

Title: Adaptive fuzzy controller that modifies membership functions
Inventor: WOESSNER MICHAEL A
IPC: F24D19/10
Filed: 1997-06-23
Abstract: A direct adaptive fuzzy controller having an adaptation mechanism that modifies the locations of output membership functions to improve performance of the fuzzy controller. The controller has a fuzzy rule base that has a different or unique output membership function for each fuzzy rule. The adaptation mechanism modifies the location of the output membership functions in response to the performance of the controller system, to continuously improve its performance. The controller is a feedback mechanism that functions not only using measured outputs of the process controlled, but has feedforward compensation that causes the controller to anticipate feedback due to measured disturbances or other parameters of the process. The adaptive fuzzy controller can be used for various processes, including combi-boiler domestic hot water temperature control, automobile cruise control, a residential thermostat, duct air temperature or static pressure control for the air handling unit in a heating ventilation and air conditioning system, and furnace temperature control for curing parts.

Patent CA-2257441-A1 (CA)
Inventor: HERBERT MARK S
IPC: E04F17/12
Filed: 1999-01-13
Abstract: A dust and debris disposal system is adapted to be mounted in an opening formed in a floor, and is used in conjunction with a dust and debris gathering device such as a broom or a mop. A housing is fixed to a flat upper surface of the floor and includes an inclined debris ramp, a raised support shell joined to the debris ramp and a downwardly depending neck extending through the opening in the floor. The debris ramp is defined by a ramp inlet formed by a peripheral edge of the housing, a ramp rim located inwardly from the ramp inlet and provided with a pair of ends, and a pair of spaced ramp curbs. Each of the curbs extends inwardly and upwardly at an inclined angle with respect to the ramp inlet and intersects with one end of the ramp rim. The support shell is formed with a sweep ridge extending opposite the ramp rim and at an elevation above the ramp rim. The ramp rim, the sweep ridge and the housing define a dust and debris orifice in communication with the tubular neck. A tubular debris shaft is connected to the neck, and a receptacle is attached to the debris shaft. With this construction, dust and debris gathered from the floor through the use of a broom or mop is swept to the ramp inlet up the debris ramp, guided by the ramp curbs and deposited over the ramp rim into the dust and debris orifice from which the dust and debris will fall by gravity through the neck and the debris shaft to the receptacle. Dust and debris remaining attached to the broom or mop is dislodged therefrom for release into the dust and debris orifice by engaging the broom or mop against the sweep ridge and/or dust loosening ribs extending forwardly and perpendicularly of the sweep ridge.

Title: A method and apparatus for controlling optical signal power in response to faults in an optical fiber path
Inventor: RAYCHAUDHURI KAMAL KUMAR
IPC: H04B10/29
Filed: 1999-03-23
Abstract: Automatic reduction of optical signal power supplied by an upstream network element by a prescribed amount is achieved by capturing and processing reflected optical energy that is generated within the optical fiber path as a result of a downstream fiber cut, open connector, or other potentially hazardous discontinuity. Generally, the power level of the reflected optical signal is detected and measured in the optical fiber path and the optical signal power supplied by the upstream network element is automatically reduced. The optical signal power may either be reduced by an amount corresponding to the measured reflected optical signal power or may be completely shut off until the faulty condition is resolved. In one illustrative embodiment, an apparatus for automatically reducing or shutting off the optical signal power supplied by an upstream network element includes a directional optical transfer device disposed along the optical fiber path and coupled to the output of a network element, an optical power monitor for measuring the reflected optical energy received via the directional optical coupler as a result of a downstream fiber discontinuity, and control circuitry coupled between the power monitor and the network element to control the optical signal power being supplied by the network element based on the monitored power level of the reflected optical signal. The control circuitry may be analog, digital, or may be implemented using a microprocessor operating under software or firmware program control.

Inventor: AALTONEN PASI
IPC: F22B1/18
Filed: 1997-10-23
Abstract: The invention relates to a waste heat boiler (1) with variable output, working by natural circulation. The steam/water cylinder (2) functions as a steam (7) and feed water (8) storage tank. All the exhaust gas (52) flows through the convection part (41), whereby the heat transfer surfaces are automatically cleaned due to the high flow velocity. The production of steam (7) is controlled by changing the water level (48) and quantity in the convection part (41). The basis of the control are the different heat transfer characteristics of the liquid and the steam. The steam/water cylinder (2) is connected to the lower end of the convection part (41) by means of the drain pipe (19), wherein is provided valves (20) controlling the water level (48), which may be either continuously adjustable or of the open/closed type. A separate control circuit controls the feed water level in the steam/water cylinder (2).  Different feed pipe (6) and baffle (47) arrangements heat the feed water (8) and condense the steam (7).

Title: Apparatus and methods for stacking forms and moving the stacked forms selectively in one of two directions
Inventor: PARKER REBECCA L
IPC: B65H31/28
Filed: 1998-09-21
Abstract: A bi-directional stacking conveyor (10) is mounted below the discharge from a main conveyor and lies substantially perpendicular to the main conveyor. An adjustable length backstop (30) and adjustable width guide fingers (34A, 34B) are carried by the stacking conveyor (10) to accommodate forms of different lengths and widths, the backstop (30) and side guides (34, 34B) holding the sheets snugly in the stack. In response to a signal from a controller, the guide fingers (34A, 34B) on a side of the stack in the direction of desired movement are displaced to an out-of-the-way position and a motor drives the stacking conveyor belt to displace the stack in a first direction. At the end of a job or completion of a count and responsive to a signal to move the stacked sheets in an opposite direction, the controller operates the stepper motor for the opposite fingers to displace those fingers out of the path of movement of the stacked sheets in the opposite direction so that the motor is reversed and the conveyor belts displace the stacked sheets in the opposite direction.
