Abstract: Systems and methods are disclosed that use microbes as active sensors to make microscopic measurements across surfaces, such as large geographical surfaces. The methodology can image large physical areas with high resolution hyperspectral data, create a dataset that can be analyzed to develop an image analysis model, and then leverage hyperspectral images to determine the presence of materials (chemicals, pathogens, minerals, etc.) of interest. The systems and methods enable a user to identify the target within hyperspectral data, without the need to utilize microbes to measure areas beyond their initial use as labeled training data.

Abstract: A drill piping or tubing pressure seal includes a diameter-spanning body portion. The diameter-spanning body portion includes a high-pressure side, a low-pressure side and a plug receptacle passing through the diameter-spanning body portion from the high-pressure side to the low-pressure side. The high-pressure side and the low-pressure side of the diameter-spanning body portion include a protective coating; however, an interior surface of the plug receptacle located between the high-pressure side and the low-pressure side does not include the protective coating. In addition, a plug is configured to be located within the plug receptacle, and the plug is configured to be retained within the plug receptacle by an anchor element to maintain the plug within the plug receptacle until a breakaway force of the anchor element is exceeded. A gasket is located between a portion of the plug and the plug receptacle.

Abstract: A variable demand radiant heating system applies variable burner control technology to singular or multi-burner radiant heating systems. A radiant heater consists of a burner connected to an elongated heat exchanger tube. The combustion air is supplied to the burner via blower or draft inducer. Fuel is supplied to the burner via fuel regulator. Fuel and air are mixed in burner and communicated to the inlet end of the heat exchanger tube. Spent products of combustion are expelled from the heat exchanger at the outlet end. The burner controls continuously vary gas supply pressure (volume), via a modulating gas regulator, and combustion air pressure (volume), via a variable speed blower, communicated to the burner mixing chamber, which in turn, varies the burner input on a continuous curve (not stepped or staged) within a pre-determined input range as heat demand varies.

Abstract: During fabrication, a rotating semiconductor substrate is radiated in accordance with a thermal recipe. Temperature measurements of the semiconductor substrate are obtained along with the position of the semiconductor substrate at the time of each temperature measurement. It is then determined for the position of the semiconductor substrate whether at least one particular temperature measurement of the temperature measurements should be filtered. If so, at least one filtered temperature measurement is obtained. The radiation of the semiconductor substrate is subsequently controlled based on the temperature measurements, the at least one filtered temperature measurement, and the thermal recipe.
