Abstract: Systems, including devices and methods, for infrared imaging, and more particularly to systems for infrared imaging.

Abstract: An infrared (IR) camera and associated electronics including power are systems, including devices and methods, for infrared imaging that can be switched or reprogrammed to produce or display at least two images associated with at least two temperature ranges.

Abstract: An infrared (IR) camera and associated electronics including power are integrated into portable, self-contained, vision-enhancement apparatus useful in environments of dense air-borne particulate and thermal extremes such as encountered in fire fighting situations, in accordance with the invention. The IR camera is integral with a self-contained power supply so that the system is portable and requires no umbilical cord or other external connections. The camera includes an imager that is preferably an un-cooled focal plane array, and associated imaging, storing, processing and displaying electronics that are cooled in the extreme thermal environment using an integral plural phase heatsink.

Abstract: A head-up display, an IR camera and associated electronics including power are integrated into portable, self-contained, wrap-around, face-worn vision-enhancement apparatus useful in environments of dense air-borne particulate and thermal extremes such as encountered in fire fighting situations, in accordance with the invention. Reflective and opaque lenses are provided at approximately eye level for IR, vision display and blinding purposes, respectively, to produce a clear bright picture of a scene otherwise obscured by darkness or obscurants. The IR camera is integral with wrap-around system along with a self-contained power supply so that the system is portable and requires no umbilical cord or other external connections. An optical axis of the IR camera and an axis describing the user's virtual line of sight through the viewing eye converge at a nominal arm's length in front of the user's viewing eye, e.g. 3 feet away.

Abstract: A retainer for securing the compressor rotor (172) to the compressor-turbine shaft (160) of a turbocharger includes a retaining sleeve (180) having an aperture therethrough for mounting the sleeve onto the shaft adjacent the compressor rotor to prevent movement of the rotor on the shaft in the direction of the sleeve. The sleeve has an inner bore (180a) having a diameter forming an interference fit on the shaft such that the sleeve prevents movement of the compressor rotor on the shaft. In one embodiment, a lug (300) extends from the sleeve (180) and engages the compressor rotor to transmit a rotational force from the shaft to the rotor through the sleeve and lug.
