Abstract: The Tidal Energy System is a structure capable of extracting energy from the potential and kinetic energies of the tides, as well as from ocean waves and offshore wind. Its components operate synergistically in multiple capacities to extract energy from these sources so that the Tidal Energy System operates as unit. The Tidal Energy System is structured so that it can be operated integrally with electrolyzer and fuel cell technology to produce on demand power thus eliminating the pulse character of conventional tidal power. The Tidal Energy System can also generate hydrogen as an end product.

Patent CA-2542404-A1 (CA)
Inventor: JAHNKE RUSSELL CARL
IPC: F02M33/08
Filed: 2006-04-07
Abstract: A vapor vent/tipping valve has a diaphragm with a bleed therethrough responsive to the differential pressure of bleed flow to control vapor venting to the canister and vapor recirculation to the filler tube. A dip tube causes rising fuel in the tank to close the dip tube and prevent vapor flow to the diaphragm bleed thereby starving the recirculation line and allowing nozzle discharge to create a vacuum in the filler and effect nozzle shutoff. Alternatively, float operated shutoff valves may be employed in the dip tube and vapor vent chamber inlet. The shutoff valves may include inertial members for closing the float valves to afford tipping/rollover protection.

Title: Occupancy sensor and method of operating same
Inventor: KONRADI VADIM A
IPC: G05B15/02
Filed: 1998-02-04
Abstract: A multiple sensing technology-based occupancy sensor. Ultrasonic and infrared sensors are used to produce first and second occupancy estimator signals that are combined using a fusion based detection algorithm to produce a combined estimator signal. The combined estimator is then used to switch electrical loads when the combined estimator signal is above a predetermined threshold. The result is an occupancy sensor that has a very high probability of occupancy detection and a low probability of false tripping. In addition, infrared sensitivity is adjusted based upon an estimation of the background noise in order to minimize the occurrence of false tripping.
