Abstract:
A micro-electro-mechanical systems (MEMS) inertial measurement system facilitates accurate location and/or attitude measurements via passive thermal management of MEMS inertial sensors. Accuracy of the system is also improved by subjecting the inertial sensors to programmed single-axis gimbal motion, and by performing coarse and fine adjustments to the attitude estimates obtained by the system based on the programmed motion and on the passive thermal management of the sensors.

Abstract:
A humidifier assembly comprising a housing that is open at the rear for slidable insertion of a frame carrying a motor driven endless porous water pickup pad and a bottom mounted water reservoir pan. When the housing is mounted on a plenum or the like these and other components within the housing are not accessible for removal from the housing. A special sheet metal subassembly mounts the pad and its supporting rollers and a motor for driving one of the rollers.
