Methods for manufacturing an apparatus for testing an ultrasonic gas leak detection device and methods for testing an ultrasonic gas leak detection device are disclosed. An example method includes disposing a rotary selector around a housing, disposing a rotary position sensing device within the housing, disposing a button on the housing, and disposing an ultrasonic transduction device within the housing, wherein the ultrasonic transduction device is configured to generate a first ultrasonic signal for testing the ultrasonic gas leak detection device when the first rotary position corresponds to the first testing mode and the button simultaneously corresponds to the depressed state, and generate a second ultrasonic signal for testing the ultrasonic gas leak detection device when the second rotary position corresponds to the second testing mode and the button simultaneously corresponds to the depressed state, wherein the second ultrasonic signal is different from the first ultrasonic signal.

Handheld ultrasonic testing device

Methods, apparatuses, and systems for diagnosing misalignment in gas detecting devices are provided. An example method may include causing at least one detector component of a receiver element of the open path gas detecting device to generate a first light intensity indication corresponding to first infrared light; causing the at least one detector component to generate a second light intensity indication corresponding to second infrared light; and generating an alignment indication based at least in part on the first light intensity indication and the second light intensity indication.

The example apparatus for testing an ultrasonic gas leak detection device includes a button configurable between an un-depressed state and a depressed state and an ultrasonic transduction device. The ultrasonic transduction device is configured to generate a first ultrasonic signal for testing the ultrasonic gas leak detection device in response to a first determination that the apparatus is in a first testing mode and that the button simultaneously corresponds to the depressed state, and generate a second ultrasonic signal for testing the ultrasonic gas leak detection device in response to a second determination that the apparatus is in a second testing mode and that the button simultaneously corresponds to the depressed state, wherein the second ultrasonic signal is different from the first ultrasonic signal.

Apparatuses, systems, methods, and computer program products for flame detection are provided. An example of a flame detection apparatus includes an infrared sensor to generate infrared sensor data and a thermal camera to capture one or more thermal images and generate thermal image data. The flame detection includes detecting if a flame is present in an environment based on the infrared sensor data and the thermal image data, including determining if one or more false alarms are present. The flame detection may also be based one or more spectral features or thermal features.

An example method includes determining a rotary position of a rotary selector of the handheld ultrasonic testing device. The method further includes determining whether the rotary position of the rotary selector corresponds to a first testing mode for testing the ultrasonic gas leak detection device or a second testing mode for testing the ultrasonic gas leak detection device. The method further includes generating a first ultrasonic signal for testing the ultrasonic gas leak detection device in response to determining that the rotary position of the rotary selector corresponds to the first testing mode. The method further includes generating a second ultrasonic signal for testing the ultrasonic gas leak detection device in response to determining that the rotary position of the rotary selector corresponds to the second testing mode.

Embodiments relate generally to systems and methods for filtering unwanted wavelengths from an IR detector. In some embodiments, it may be desired to remove or reduce the wavelengths absorbed by water, to reduce the effects of water on the detection of the target gas. In some embodiments, a filter glass may be used in the IR detector, wherein the filter glass comprises one or more materials that contain hydroxyls in their molecular structure, and wherein the spectral absorption properties of the filter glass are operable to at least reduce wavelengths of light absorbed by water from the optical, thereby reducing the IR detector's cross sensitivity to water.

Use of selected glass types and glass thicknesses in the optical path to remove cross sensitivity to water absorption peaks

Example computer systems, computer apparatuses, computer methods, and computer program products are disclosed for detecting a gas leak. An example computer method includes receiving an electronic indication of a monitoring mode and determining whether the monitoring mode corresponds to a standard mode or a focus mode. The example computer method further includes, in response to determining that the monitoring mode corresponds to the standard mode: monitoring a first range of ultrasonic frequencies to generate a first set of monitored data; and generating a first ultrasonic gas leak detection signal based on the first set of monitored data. The example computer method further includes, in response to determining that the monitoring mode corresponds to the focus mode: monitoring a second range of ultrasonic frequencies to generate a second set of monitored data; and generating a second ultrasonic gas leak detection signal based on the second set of monitored data.
