A combination light and pressure relief vent is disclosed which includes a housing, a valve assembly, and a light assembly. The housing include a valve body, port tube, and an outside louver. The valve body has a low positive pressure exhaust port, a high positive pressure exhaust port, a low negative pressure intake port, and a high negative pressure intake port. The valve assembly includes a low positive pressure exhaust valve, a high positive pressure exhaust valve, a low negative pressure intake valve, and a high negative pressure intake valve. The light assembly includes a heat sink casing which defines a heat chamber. The casing is coupled to an LED module wherein heat generated by the LED module is transferred through the casing to the heat chamber to warm the valve assembly.

An automated window mechanism with sensor informed calibration is disclosed. An electrically powered actuator moves a window between a closed position and an open position. A current sensor senses the current between a power source and the actuator when the actuator is moving the window. Informed by the current sensor, a processor determines a first endpoint when the window is in the closed position and a second endpoint when the window is in the open position for the window. A controller uses the endpoints to control the actuator to stop in either the first or the second endpoint as desired by a user. Sensors inform the controller, and user input via a mobile device enables both direct user control and programming of the controller.

A drilling system for use at a wellhead has a plurality of modules each containing rig component equipment. The plurality of modules are connected or interconnected together so as to form a drilling rig. Each of the plurality of modules has a size adapted to be lifted by forklift or a front end loader. The plurality of modules are arranged such that one end of the plurality of modules is adjacent to the wellhead. A pipe handling system is positioned adjacent to one end of the plurality of modules. A ventilation system is cooperative with the plurality of modules so as to move air toward or away from heat-generating equipment in the plurality of modules.

A grossing station comprising a table and an overhead hood connected to the table. The grossing station further comprising a plurality of interchangeable plates arranged in a trough of the table and a lift system connected to the table. The grossing station also comprises a touch screen controller arranged on a surface of the station, wherein the touch screen controller is in communication with at least one manual toggle switch for overriding an electronic control and monitoring system if a system failure occurs within the grossing station.

An assembly for controlling the position of air inlets of an enclosure including an actuation rod which moves laterally and is positioned above and parallel with the air inlets, one or more actuation cables, where the first end of each actuation cable is attached to the actuation rod and the second end of each cable is attached to one or more of the air inlets and lateral movement of the actuation rod causes vertical movement of the actuation cables and attached air inlets.

One aspect of the disclosure provides a termination for use with a furnace. The termination, in one embodiment, includes a face plate including an exhaust region and an air supply region, the face plate having a front surface and an opposing back surface. The termination, in this embodiment, further includes an exhaust termination portion extending from the back surface in the exhaust region, the exhaust termination portion capable of engaging a terminal end of a variety of different size exhaust conduits associated with a furnace. The termination, in this embodiment, further includes an opening extending through the face plate in the exhaust region, the opening aligned with the exhaust termination portion.

A ventilation system includes an inside air passage having inflow and outflow ends communicating with an indoor space to be ventilated, at least one permeable film unit including a permeable film, and an air supply passage having an inflow end communicating with an outdoor space and an outflow end connected to a downstream side of the permeable film in the inside air passage. The permeable film allows a target gas to pass and allows the target gas that has passed through the permeable film to he discharged into outdoor air. The target gas contains at least one of carbon dioxide and a volatile organic compound in indoor air that flows in the inside air passage. Alternatively or in addition, the ventilation system can include an outside air passage and a discharge passage in place of or in addition to the inside air passage and the air supply passage, respectively.
