Abstract: An endoscopic camera system having a camera with a shaft coupled to a handpiece; and a sheath with hollow tube coupled to a body. The tube has: a proximal portion coupled to the body; a bend at a distal end of the proximal portion; and a distal portion distal to the bend. The sheath is configured to deflect the shaft and the sheath is rotatable around the shaft to change a direction of the deflection.

Abstract: A humidity control system for an enclosure includes a housing having a process air duct and a regeneration air duct, with return air from the enclosure and/or atmospheric air being supplied to the process air duct and atmospheric air being supplied to the regeneration duct. A desiccant wheel is rotatably mounted in the housing for rotation through the ducts for absorbing moisture in the process air duct and releasing moisture in the regeneration duct. A refrigeration system including a condenser coil in the regeneration duct upstream of the desiccant wheel is connected to a heat pump which includes a heat exchanger and a recirculating fluid loop connected between the condenser coil and the heat exchanger for transferring heat from the recirculating fluid loop to said reactivation airstream.

Abstract: A remote firing system for remotely detonating explosive charges includes features that provide safety and efficiency improvements. These features include safety communication among multiple remote devices and multiple controller devices, a polling functionality permitting rapid deployment of system devices, electronic key systems, and programmable remote devices for easy replacement of failing remote devices.
