Patent CA-2415685-C (CA)
Inventor: GUNTHER JOHN C

Abstract: A control system for automatically achieving and maintaining a desired sodium/phosphate ratio and phosphate concentration of the boiler water in an industrial. boiler for minimizing corrosion. The system uses an adaptive controller that models the boiler which enables the system to predict boiler pH and phosphate concentrations at any future time given the feed rates, feed concentrations of high and low sodium/phosphate stocks, blowdown rate, mass of the boiler water, initial boiler phosphate concentration and initial pH. Once these future concentrations are determined, the controller then determines which feed rates will return the current boiler water state to, and then maintain the boiler water at, the desired sodium/phosphate congruency ratio in the least amount of time. Where the controller determines that it is not possible to move the current boiler water state to the desired congruency setpoint, the controller determines a feed rate program that will move the current boiler water state to the attainable steady state point closest to the desired setpoint. An alternative embodiment fixes the phosphate concentration by ratioing the phosphate feed with the blowdown rate while continuously monitoring blowdown pH. This arrangement allows for the control of sodium by switching between the high and low ratio sodium/phosphate stocks based on the measured pH with respect to the pH setpoint.

Abstract: A proxy switch, communication methods, and communication logic for use in a mobile network are described. A proxy switch is deployed between a base station subsystem and a mobile station center. A FSN and a BSN are provided for communication with the MSC, and another FSN/BSN pair are provided for communication with the BS. Logic detects whether a received message is a change over order message (COO) from one of the MSC and BS, indicating a break in a first signaling link between the proxy switch and the one of the MSC and BS, and logic generates and sends a COA message to the one of the MSC and BS containing the BSN maintained by the switch for communication with the one of the MSC and BS. Fault emulation logic forces a break in a second signaling link between the proxy switch and the other of the MSC and BS, wherein the second signaling link is configured to correspond to the first signaling link, and generates and sends a new COO message to the other of the MSC and BS.

Abstract: Video encoding and decoding processes provide compression and decompression of digitized video signals representing display motion in video sequences of multiple image frames. The encoder process utilizes object- or feature-based video compression to improve the accuracy and versatility of encoding interframe motion and interframe image features. Video information is compressed relative to objects or features of arbitrary configurations, rather than fixed, regular arrays of pixels as in conventional video compression methods. This reduces the error components and thereby improves the compression efficiency and accuracy. The decoder process decompresses the encoded video information to reconstruct the objects or features of arbitrary configurations.

Filed: 2002-05-07
Granted: 2007-11-27
Abstract: A liquid flow meter (50), including a microcontroller (60) and associated algorithm, monitors urine flow through a cartridge trap (20). Measuring the duration of such flow and the number of times the urinal is used will determine, in accordance with preset criteria, when servicing or replacement is needed, and alerts a service person to that effect by a warning light (68) or other signal. Because urine has a high mineral content, it is electrically conductive, effective to complete circuits between closely spaced metal contacts (62a-62c, 64a-64c) coupled to the PROM, which allows the manner and existence of the urine to be detected. The liquid flow meter is installed in the cartridge trap by utilizing and placing a split ball stem (52) located at the base of the meter into a mounting hole (42) located in the center of the drain holes (36) on the cartridge cover (26).

Abstract: An electro-hydraulic operating system for an extensible boom includes one or more hydraulic cylinders for imparting relative motion between the boom sections to retract the boom according to an electronically stored program of sequences of movement and speeds. A source of pressurized hydraulic fluid is fed through appropriate control valves which include solenoid valves in fluid communication with a source of pressurized hydraulic fluid. The solenoid control valves are supplied with control currents proportional to the desired flow rates of fluid to the hydraulic cylinders in order to achieve speed and position control according to the stored program. A metering valve structure is provided for operation in conjunction with the solenoid control valves. The metering valve includes an associated pilot valve which receives variable pressure signals from the solenoid control valves to achieve the metering of fluid to the hydraulic cylinders in proportion to the characteristics of the control current supplied to the solenoid valves. The electrical control signals are such that the hydraulic cylinders may move associated boom sections at gradually increasing speeds during a starting period of any cycle of movement of the section, at a substantially constant speed during an intermediate period of movement and at a gradually decreasing speed during a stopping period preceding the end of the cycle of movement, thereby providing soft start and soft stop of the sections.
