Abstract: A breath alcohol testing device has a removable tamper-resistant sampling chamber assembly that provides a disposable interface between the test subject and the alcohol sensor, other sensors and electronics of the testing device. Hydrophobic membranes prevent bodily fluids and other liquids from entering the alcohol sensor and other sensitive components of the testing device. A set of chambers with one-way valves direct the gas flow within the sample chamber assembly to ensure the breath sample delivered to the alcohol sensor is not diluted by the subject inhaling, and is a deep-lung breath sample.

Abstract: Leaks in a roof membrane are detected by applying a grid of electrically conductive shielding elements on the upper surface separating the membrane into a plurality of zones and generating a potential difference between the elements and a conductive component such as the roof deck or a layer at the deck. In each zone a respective one of a plurality of sensor conductors is mounted separate from the shielding elements and an electrical potential difference is applied between the sensor and the conductive component such that, in the presence of a leak located within the zone, current flows between the sensor conductor and the conductive component through moisture at the leak for detection of the current or resistance indicative of a leak.

Abstract: A modular soldering station includes a first platform having a liquid reservoir and a solder dispenser, a power supply assembled to the first platform and configured to power a soldering iron, and a second platform assembled to one of the first platform or the power supply and having a fluid absorbent medium fluidly coupled to the liquid reservoir.

Abstract: A gas-lift plunger includes a body having an upper end, a lower end, a bore extending axially from the upper end to the lower end, and a port therein that is in communication with bore, and an obstructing member positioned in the bore. The obstructing member includes a valve stem and is movable between a closed position, in which the obstructing member substantially prevents fluid flow through the bore from the port to the upper end, and an open position, in which fluid flow through the bore from the port to the upper end is permitted. The plunger includes an end nut connected to the lower end of the body, and a clutch assembly including arcuate members that are positioned at least partially around and configured to engage the valve stem to impede movement thereof. The clutch assembly is positioned at least partially within the end nut.

Abstract: An inverter phase leg for a DC-AC inverter includes a high supply line and a low supply line across which a DC voltage is provided. A high side gate controlled switch is connected to the high supply line and a low side gate controlled switch is connected to the low supply line, with an output node between the high side switch and the low side switch. An inverting driver is connected to the high side gate controlled switch. The inverting driver's voltage source is configured in such a way as to hold the high side gate controlled switch off during the turn on cycle until the driver output has overcome the negative bias generated across the high side switch gate, producing high immunity to spurious turn on. A digital isolator is connected between the inverting driver and a control signal for switching the inverter phase leg. A differential transmitter and differential receiver may be used to further increase noise immunity.
