It is described herein a venting apparatus for an opening in a roof. The venting apparatus for an opening in a roof may comprise a structural frame, an adapter, a mount, a hinge, and a latch. The adapter may comprise a frame adapter section, a lip extending inwardly from a portion of the frame adapter section inner surface, and a protrusion extending upwardly from the lip. The frame adapter section may be configured to fit around an outer surface of the structural frame while the mount may be configured to fit around an outer surface of the protrusion. The latch may be configured to receive a signal from a device when the device detects the presence of smoke within the building to cause the latch to change from a latch closed position to a latch opened position.

A safety cabinet can include an enclosure defining an interior compartment accessible through an opening. The safety cabinet includes an interior lighting system. The interior lighting system can include at least one of an illuminating light to enable viewing to cabinet contents and an ultraviolet light configured to disinfect the interior compartment of the safety cabinet. To provide electrical power to the interior lighting system, the safety cabinet includes an electrical connection disposed through the enclosure. The electrical connection can include at least one of a bulkhead connector and an intumescent socket.

Disclosed herein is an apparatus for variable fluid damping. The apparatus comprises a mount. The apparatus also comprises a damper coupled to the mount to apply a damping force in response to movement of the mount. The apparatus further comprises an electrical element positioned to correspond to the damper. The apparatus additionally comprises a rheological fluid disposed in the damper. The rheological fluid changes viscosity in response to a change in an output of the electrical element to change the damping force of the damper. The apparatus also comprises a controller to provide input to the electrical element in response to a normal operating condition or an emergency operating condition.

A dampening system (28) that includes an actuation state and/or a door actuation system that includes a single-use pressurized tank (34). The dampening system or the door actuation system may include a damper (30) and a fluid pressure source (e.g., the single-use pressurized tank (34)) that pressurizes the damper to actuate from a first position to a second position. The pressurization allows the damper to actuate another component, such as a vehicle door (26) that is operably coupled to the damper. A user may shift the damper into the actuation state to actuate the vehicle door open during an emergency, such as when a military vehicle is on its side after an explosion knocks over the vehicle and the vehicle door is too heavy for the user to open without assistance.

A harvesting machine includes a chassis, a ground-engaging mechanism for supporting the chassis, and a tank assembly mounted to the chassis for storing a crop material. The tank assembly includes a retractable door for at least partially covering an opening formed in a top of the tank assembly. A mobile sensor assembly includes a rod and a sensor for detecting a weather condition, such that the rod includes a first end coupled to the retractable door and a second end to which the sensor is coupled. The retractable door is operably moved between an open position and a closed position, and the mobile sensor assembly is rotatably moved between a deployed position and a stowed position as the door is moved between the open and closed positions, respectively.

A fenestration automated operating system includes a fenestration frame, fenestration panel and one or both of a panel operating assembly or a panel latch assembly. The panel operating assembly is coupled with one or both of the fenestration frame or the fenestration panel. The panel operating assembly includes a panel actuator coupled with the panel actuator. A panel latch assembly is coupled with one or both of the fenestration frame or the fenestration panel. The panel latch assembly includes a latch and a latch actuator coupled with the latch. A fenestration controller is configured to operate each of the latch actuator and the panel actuator.

A rear door assembly includes a rear opening and a roof structure having a recessed area. A carrier is movable along a portion of the recessed area between a rearward location to a forward location. A motor is attached to the carrier and the vehicle. The motor is operable to move the carrier relative to the roof structure and the rear opening between the rearward location and the forward location. A rear door has a hinge pivotally supported to the carrier for movement therewith. The rear door is movable between a door closed orientation covering the rear opening, an intermediate orientation partially exposing the rear opening and a door open orientation exposing the rear opening. A linear movement device has a first end attached to the carrier for movement therewith and a second end attached to the rear door at a location spaced apart from the hinge.
