A barrier door may include a section including an outer stationary portion and an inner movable portion disposed within the outer stationary portion, an actuator, and a controller. The actuator may move the inner movable portion between different positions to control flow of air between a protective enclosure and a volume outside of the protective enclosure. The controller may monitor one or more operating characteristics of the actuator and may modify an operational status of the actuator to control the flow of the air between the protective enclosure and the volume outside of the protective enclosure based at least in part on the one or more operating characteristics.

Enclosure for a vehicle system

A door actuation system may include an actuation device to move a first door leaf and a second door leaf between an open and a closed position. The actuation device may provide an open preload force in the open position. The actuation device may provide a closed preload force in the closed position. The system may include one or more of: a first engagement member that may contact the actuation device and may allow movement of the actuation device to adjust the open and closed preload force; or the actuation device may be coupled with the first door leaf by a first rod and the second door leaf by a second rod, at least one of the first or second rod may adjust a length of the first or second rod to maintain the open preload force in the open position and the closed preload force in the closed position.

Door actuation system and method

A barrier door for a protective enclosure includes a lower section and an upper section operably coupled with the lower section, and a ventilation system disposed within the lower section. The ventilation system includes one or more blowers and a plenum. The ventilation system is configured to direct air one or more of into or out of the protective enclosure.

A self-contained water cooler module for use with a water dispenser includes a chassis. The chassis includes a back panel, a pair of spaced side panels extending forwardly from the back panel, a bottom panel extending forwardly from the back panel and attached to bottom edges of the pair of spaced side panels, and the back panel, side panels and bottom panel are constructed of a single, unitary sheet. A strut interconnects front edges of the pair of spaced side panels. A support bracket interconnects the back panel and the horizontal frame member. A refrigeration unit includes an evaporator, a condenser, a fan and motor assembly, and a compressor. The refrigeration unit is attached to the chassis. A water storage tank is configured to receive cooled water from the refrigeration unit. The chassis is configured to be attached to and detached from the water dispenser via a tool-free connection.

Modular water cooler and method

A barrier door for a protective enclosure includes a lower section and an upper section. The upper section includes an outer stationary portion and an inner movable portion disposed within the outer stationary portion. The outer stationary portion and the inner movable portion are light transmissive. The inner movable portion is movable in a vertical direction and is coupled to a lift device disposed in the lower section. The lift device is configured to move the inner movable portion between a lowered position in which the inner movable portion is at least partially withdrawn into the lower section to form an opening in the upper section and a raised position in which the inner movable portion is extended to close the opening.

Illuminated sink

A rotational position sensing device for sensing rotation of an axially adjustable shaft of a shaft and arm assembly of a door that does not require readjustment after the shaft and arm assembly are adjusted includes a fixed bracket supporting a post, a position sensor having an upper portion, a lower portion and an extended portion, and a rotating portion. The extended portion extends from the upper portion of the position sensor and constrains the post of the bracket such that the upper portion of the position sensor is unable to axially rotate relative to the bracket. The rotating section is adapted to be fixed to the shaft and engage with the lower portion of the position sensor, such that the rotating portion rotates relative to the upper portion of the position sensor.

Position sensing device for transit shaft and arm assembly

According to this invention there is provided an adjustable base plate structure for a transit door comprised of a plurality of fixed dimension elements and a plurality of variable dimension elements for accommodating a plurality of door sizes and types. The base plate structure comprises a roller channel for spanning the width of the door and a center brace for being secured to the channel centered on the roller channel. Mounting brackets are secured to the vehicle or door frame and the roller channel.

Base plate structure for transit doors

A height adjustment device for a transit shaft and arm assembly that enables height adjustments without significant disassembly of a transit door. An additional advantage is that the device does not require the use of shims, spacers or adjustment rings to adjust the height of the shaft and arm assemblies. Rotation of a nut threaded on the shaft allows for the adjustment of how much of the shaft hangs below a support member and a bearing. A surface of the nut bears on the bearing and the attached shaft and arm assembly hangs from the bearing and the support member the bearing is attached to. This arrangement allows the arm assembly to pivot along the longitudinal axis of the shaft. This arrangement also allows the height of the shaft and arm assembly to change with changes in position of the nut by threading the nut along the shaft.
