Title: Crossflow with crossmirror and lock out capability valve
Inventor: WOLFE C BRIAN
IPC: F15B20/00
Filed: 1997-11-12
Abstract: A control valve system has two valve trains each of which has a series of valves which dynamically move between a deactuated position and an actuated position. An inlet of the valve system is connected to an outlet of the valve system when all of the valves are actuated and the outlet of the valve system is connected to an exhaust when all of the valves are deactuated. Each valve train includes asolenoid valve which when actuated moves the remaining valve members to their actuated position. The various valves of each valve train are interconnected with the valve of the other valve train such that actuation of all of the valves in a substantially simultaneous manner will connect the inlet of the valve system to the outlet of the valve system and deactuation of all of the valves in a substantially simultaneous manner will connect the outlet to the exhaust. The valve system monitors the dynamic movement of the valve members during its operation will move to a locked out condition when any valve is in a deactuated position and when one other valve is in an actuated position. In the locked out condition, the outlet of the valve system is connected to the exhaust. In one embodiment, The valve system will remain in this locked out condition until a resetting operation is performed. In an additional embodiment, the valve system will automatically reset itself

Title: Occupancy sensor and method of operating same
Inventor: HARDIN CHARLES C
IPC: H05B37/02
Filed: 1996-02-05
Abstract: An occupancy sensor that provides improved performance by the inclusion of a microprocessor that controls the sensing transducers and processes the received signal to optimize desired detection performance. The occupancy sensor includes a quadrature detection technique and automatic sensitivity adjustment that reduce false detection caused by air flow, hallway traffic and other noise sources. A fault detection method executed periodically detects fault conditions in the sensor or sensing area caused by component failure or obstructions in front of the sensor. Transmitter power is varied depending on the size of the desired coverage area. Since various ambient parameters such as line voltage, light level, and temperature may be easily and usefully monitored, the microprocesor may use these variables to make intelligent decisions in controlling electrical loads, such as building lighting and ventilation.
