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

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.

Handheld ultrasonic generating device for testing gas leak detectors

Various example embodiments described herein relate to a window heating apparatus. The window heating apparatus comprises a frame, a heater assembly disposed on the frame, and a glass window. The heater assembly comprises a base having a first side and a second side and defines a first opening. The heater assembly comprises a Printed Circuit Board (PCB) laminated on the first side of the base along an inner edge of the base. The PCB defines a second opening, wherein the first opening and the second opening are aligned coaxially. The glass window is disposed on the base and the second side of the base is in direct contact with the glass window.

Methods, apparatuses, and systems related to gas detection are provided. For example, an example apparatus for gas detection in an air duct component that receives a gas flow associated with gaseous substance is provided. The example apparatus includes a suspension connector component and a gas detection component. The suspension connector component includes a first end that is connected to a gas detection component so that the gas detection component is suspended within the air duct component. The gas detection component includes an asymmetrical outer housing so that the gas flow causes a randomized motion of the gas detection component within the air duct component.

Apparatus, system, and method for gas detection in air duct systems

Example computer systems, computer apparatuses, computer methods, and computer program products are disclosed for testing an ultrasonic gas leak detection device. 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.

Example systems, apparatuses and methods are disclosed for detecting a gas leak. An example system comprises a sensor sub-module, a processor sub-module, and a barrier structure configured to restrict flame spread between the sensor sub-module and the processor sub-module. The barrier structure comprises a first housing part, a second housing part, and a printed circuit board disposed in a cavity structure formed by the first housing part and the second housing part. The barrier structure further comprises a first electrical connector configured to provide a first electrical connection to the sensor sub-module. The barrier structure further comprises a second electrical connector configured to provide a second electrical connection to the processor sub-module.
