Title: A detector system with adjustable field of view
Inventor: PORTER JAMES A
IPC: H05B37/02
Filed: 1997-09-17
Abstract: A sensor system to turn on room lights when a person enters such room but avoids nuisance tripping of the system when a person passes near but outside of the region to be monitored. The inclusion of blinder devices which can be individually set, ahead of the sensor elements, permit the region being monitored to be tailored to the particular room or location. Adjusting levers can be used to set the positions of the blinder devices and then covered to prevent tampering with the settings of the blinder devices.

Title: A high availability asynchronous computer system
Inventor: BEYERLEIN RUTH
IPC: G06F13/16
Filed: 1998-10-29
Abstract: A method and apparatus for receiving status information from shared logical memory modules in a computer system including redundant memory. The status information includes whether the shared logical memory modules are in a transitional state and the number of logical memory modules in the mirror set. When shared logical memory modules are added or removed from redundant memory they go through a transitional state when the memory card may respond to a request for data held on the card, but that data may be unreliable. Checking this status information allows better error checking of data and fault detection of the shared logical memory module.

Patent CA-2255708-A1 (CA)
Inventor: CONWAY PAUL GERARD
IPC: B64G7/00
Filed: 1997-04-10
Abstract: A spacecraft equipment panel (20) including heat pipes (HP1, HP2, HP3) operable in a zero-gravity environment for cooling the equipment (E1, E2, E3) mounted to the panel is not operable in an Earth-gravity environment because the two-phase working fluid in the heat pipes (HP1, HP2, HP3) tends to pool at the bottom of the heat pipe when the heat pipe is vertical. An apparatus and method for overcoming this condition employs infrared lamps (IR1, IR2, IR3) positioned on a mounting frame (120) to heat the bottoms of the heat pipes (HP1, HP2, HP3) to vaporize the working fluid therein, whereby the heat pipes (HP1, HP2, HP3) become operable for transporting heat while in a vertical orientation and under the influence of gravity.
