An air purifying respirator includes a dual stage fan that sucks outside air in through the filter canisters and then pushes the filtered air on to the user's mask or hood, where excess air escapes. A differential pressure sensor measures the pressure within the passages after the dual stage fan and in the ambient environment to estimate the user's rate of respiration. The microcontroller monitors the estimated rate of respiration, as well as the estimated altitude and its estimated amount of oxygen to calculate a user's filtered air flow need. The microcontroller adjusts the van via a fan controller to the appropriate air flow level. The microcontroller further monitors the battery level, filter life, and for low pressure within the user's mask and operates their respective indicators when problem levels arise. The battery supplies power to the microcontroller, power on/off button, and the dual stage fan.

A wearable sensor badge utilizes a carbon nanotube (CNT) sensor array for selective sensing of chemicals from naturally diffused air or by sampling air using a pump/fan for higher sensitivity. An embedded microcontroller monitors the resistance of the sensing elements and by using an advanced detection algorithm the presence of TICs and/or CWAs are identified.

A power distribution system has an electrical box configured to attach a power cable, a plaster ring releasably mounted to the box and one or more electrical devices installed into the ring. A pre-wired ground extends from a first end physically and electrically connected to a ground terminal on the electrical device. The plaster ring is movable between a closed position proximate the box and an open position distal the box. The pre-wired ground is configured as a lanyard so as to support the plaster ring as a wiring platform in the open position for connecting wires between the power cable and the electrical device or devices.

A stylish fold-up table has pivoting leg assemblies mounted to the underside of opposing ends of a table top. Pivoting skirts are mounted to the underside of opposing sides of the table top. The leg assemblies are erected and the side skirts are then folded down. Latches on the side skirts then engage latch receiving elements on the leg assemblies to secure the table in an erect position. In a preferred embodiment, this arrangement allows for a storable fold-up table in which all mounting hardware is hidden when erected.

A mounting assembly for mounting a device, such as a loudspeaker enclosure, through an opening in a barrier, such as a ceiling or wall of a room, including a support for positioning on the back side of the barrier adjacent the barrier opening, and at least one spring having a first end attached to the support and a second end configured for freedom of movement. The spring is held in a set position by a set latch on the support until the device is inserted through the opening and selectively engages the spring, whereupon the second end of the spring is released to allow the spring force to act on the device in a manner tending to pull the device further through the opening, toward the back side of the barrier, and into a mounted position relative to the barrier. For dismounting the device, the second end of the spring may be inserted into a retaining latch on the support by selective engagement of the spring by the device. The support includes a plurality of support members that are pivotally joined together in a manner allowing the support to be partially collapsed for insertion through the opening in the barrier and reopened on the back side.

To permit operators to change dies quickly and easily and to remove shot shells from any station, inspect them and replace them, bayonet snap in dies may be easily inserted into a tooling section of a reloader and shot shells can be removed from shell plates by pivoting the retainer free.

A clothes hanger support for a garment bag or other similar item of luggage includes a depending bracket member pivotally supporting a lower jaw member with hanger-supporting features. A closure member and latch handle cooperates with the bracket and jaw members in a closed position to hold the latter in a hanger-retaining position. Alternatively, the closure member latch handle may be pivoted to allow the jaw member to itself pivot to an open position for insertion or removal of hangers on the support. Pivotal return of the closure member latch handle to the closed position also moves the jaw member to its hanger-retaining position by cooperation of a ramp surface and ramp-follower surface of the closure member latch handle and jaw member, respectively. Preferably, the entire hanger support may be made of four unitary components which are formed of injection molded engineering polymer.
