A gas detection system is disclosed that uses an infrared illumination source and an infrared imaging detector. The infrared source is selected to emit at wavelengths corresponding to an absorption band of a gas to be detected. The region to be analyzed for the gas is illuminated, and the infrared radiation reflects off of local surfaces back to the imaging detector. At locations where the gas is present, the infrared radiation is absorbed which reduces the back reflection to the detector.

An articulating infrared window to be installed into a panel of a cabinet is disclosed. The window includes a window housing and an infrared transparent pane. The infrared transparent pane is installed within the window housing. Embodiments of the window housing can include various articulation mechanisms including individually or in combination a double gimbal assembly, a single gimbal and rotary stage, a ball and socket joint, and an extension joint (such as a bellows) for articulating the infrared transparent pane.

A visible light (VL) and infrared (IR) combined image camera with a laser pointer. The laser pointer may be used for marking a hot spot on an object or for focusing an IR lens of a camera on an object. The laser pointer may be adjacent to the VL optics and offset from the IR optics. The VL sensor array may be much larger than the IR sensor array and the camera may also display the pixels of IR data with a much larger instantaneous field of view than the VL pixels. The camera may also provide audible alarms where the alarm is emitted with a tone of variable output to indicate the relative level of the alarm.

Methods for comparing infrared image data and/or for generating infrared image comparison data are provided. In one method two image data sets are selected including visual-light and infrared image data from one or more points of view of a scene. Visual-light image data from each data set can be compared to determine an alignment correlation between different points of view for the visual-light data. The alignment correlation can then be used to correlate infrared image data from each data set. The correlated infrared image data can be compared to generate infrared comparison image data. Thermal imaging cameras capable of performing such methods are also provided.

A thermal imaging camera may be used to capture a visible-light (VL) image and an infrared (IR) image. In some examples, the camera includes a range imaging camera module that captures the VL and an infrared camera module that captures the IR image. In such examples, the VL image may include a plurality of different portions that each correspond to a different portion of the scene and distance-to-target data associated with each of the different portions of the scene. The camera may align each of the plurality of different portions of the VL image based on the distance-to-target data associated with corresponding portions of the scene so as to correct a parallax error between the VL image and the IR image. The camera may then concurrently display the VL image in alignment with the IR image.

An improved low-cost solar air heater is disclosed which utilizes an array of holes or jets in an intermediate solar window to produce impingement of the air on the upper or solar energy absorbing surface of the absorber plate to enhance heat transfer efficiency and reduce convection losses from the system.

A fluid-powered auxiliary starting system for electric motors is disclosed which includes an accumulator means for supplying an amount of fluid at high pressure to a fluid-operated motor and a clutch of similar device for connecting the output shaft of the fluid-operated motor to transfer rotational torque to the shaft of the prime mover motor to be started. The system may be either hydraulic or pneumatic and may be used to bring one or more electric motors substantially up to spaced before electric power is applied to the motors themselves. The same motor or a hydraulic or pneumatic pump may be used to recharge the accumulator between uses for electric motor starting.
