Abstract: A surface heater automatically adjusts the supply of fuel and/air to the burner in order to maintain a desired air/fuel ratio despite changes in ambient air temperature and/or pressure. The adjustment may be performed on a periodic or continuous basis and on either an open-loop basis or a closed-loop basis. The adjustment includes actuating one or more control devices that control the flow of air and/or fuel to the burner. If the adjustment is performed on a closed-loop basis, signals from a sensor can be used as feedback to control the flow of air and/or fuel into the burner to maintain a setpoint of a controlled parameter. The controlled parameter may include one or more of air mass flow rate, an intake O2 concentration, an exhaust O2 concentration, an exhaust gas composition, and an exhaust gas temperature.

Abstract: A stent device includes generally cylindrical rings aligned along a longitudinal axis, and interconnected by interconnecting members. Each interconnecting member includes a first coupling end, a second coupling end, and an elongate portion therebetween. The first coupling end, the elongate portion, and the second coupling end combine in either a first orientation or a second orientation, which are substantially mirror images. For each interconnecting member, the first coupling end can intersect with a midpoint of a transition region of a substantially repeating curved segment on one of the rings, and the second coupling end can intersect with a midpoint of a curved segment of a different and immediately adjacent ring. The interconnecting members can be arranged in rows extending longitudinally along the device. Along each row, consecutive interconnected members alternate between the first orientation and the second orientation. A cover may be provided over the stent device.

Each actuator is operable between a deployed state and a non-deployed state. A first coupling feature is disposed proximate a first edge on a first surface of the flexible member. A second coupling feature is disposed proximate a second edge on a second surface of the flexible member. The first coupling feature is configured to engage the second coupling feature when the flexible member is wrapped around the affected area and when the flexible member is slidably adjusted relative to the affected area. A retaining feature is coupled to at least one end of the flexible member and configured to retain the flexible member in a selected position on the affected area.

Abstract: A lubrication system for a machine such as a mobile generator, a mobile light tower, or a mobile jobsite heater implements an engine oil supplementation strategy from an auxiliary sump to increase service time between engine oil servicing tasks of an internal combustion engine. The system periodically introduces a supplemental volume of oil from an auxiliary sump into the engine's lubricating system during an oil supplement event. The fluid communication between the engine sump and auxiliary sump may be achieved through multiple sump connections, which may include a sump-to-sump return line that provides a liquid connection allowing oil to freely flow between the engine sump and the auxiliary sump and a vent line that provides a gaseous connection between a void space at an upper end of the auxiliary sump and a void space at an upper end of the engine sump.

The brown-out circuit is configured to extract input voltage information related to a voltage level of the mains power supply, and scale down an input voltage of the mains power supply to a DC voltage proportional to the voltage level. The controller is configured to control the plurality of lights. Wherein, power is provided from the mains power supply to the first group of lights and the second group of lights when the DC voltage is above a threshold, and power is provided from the auxiliary power supply to the first group of lights and not the second group of lights when the DC voltage is below the threshold.
