  • Patent number: 10533930
    Abstract: A gas monitoring and control system including a gas sampling chamber, sampling inlet and outlet valves, a pump and a controller. Sensors are disposed within the interior chamber that sense characteristics of a gas from a gas source and generate representative signals. The sampling inlet and outlet valves i) allow the gas into the gas sampling chamber while operating in a gas sampling state, and ii) allow ambient air into the gas sampling chamber while operating in a purge state. The pump i) causes the gas to flow through the gas sampling chamber while operating in the gas sampling state or ii) causes ambient air to flow through the gas sampling chamber while operating in the purge state. The controller causes the sampling inlet and outlet valves, and the pump to alternate operating in the gas sampling or purge state to selectively expose the sensors to the gas.

  • Patent number: 10508917
    Abstract: Exemplary practice of the present invention provides a carriage including a body having a void, a vertical rod passing through the void, four legs arranged rectangularly and projecting obliquely downward and outward from the body, and a vertical coil spring coaxially encompassing a lower portion of the vertical rod. The carriage is coupled with a retroreflective laser target at the bottom of the vertical rod whereby the top of the spring pushes against the bottom of the body and the bottom of the spring pushes against the top of the target. The target continuously adjusts in height so that the bottom of the target remains in constant spring-tension contact with the surface on which the carriage sits or travels, supported by its legs. The carriage is electromechanically propelled, and laser tracking is conducted to direct laser beams at and receive laser retroreflections from the target at various surface locations.

  • Patent number: 10495534
    Abstract: A sensor body for a flow through pressure sensor includes a strain gage surface to receive a strain gage. The strain gage surface has a curved section and a length extending along a portion of a length of the sensor body. A bore wall thickness is defined as a radial distance between the bore and an outer surface of the sensor body, including the strain gage surface. The curved section can have a substantially greater bore wall thickness over its area relative to the planar surface because a greater responsive surface area for strain measurement is available. Thus a larger strain gage may be used and pressure measurement accuracy increased.
