CPC Class H04N

Construction machine having a running-gear mechanism, a functional component, having a chassis with a cab for a driver, and monitoring cameras connected to at least one monitor in the cab in order to provide visual monitoring of work carried out adjacent to the machine, each camera having wide-angle lenses to monitor around the machine, a first camera to monitor the rear side of the machine with the camera directed in an inclined in relation to the plane (X) on which the machine stands, a second camera for monitoring the left-hand side of the machine and a third camera for monitoring the right-hand side of the machine, the second and third cameras being installed in upper left-hand and right-hand corner regions in relation to the front side of the machine with each directed at an angle of .+−.5.degree. in relation to the vertical (Y) of the plane (X) on which the machine stands.

A thermal weapon sight which includes a thermal imaging sensor, associated control and image processing computational elements, and a display includes one or more of improved reticle centering, shot indication and time lapse image capture, digital zoom, contrast enhancement that acts on displayed data only, and device features such as an eyepiece viewing option and controls disposable on a weapon that allow for weapon sight control without moving hands from weapon operation position.

A triangulation scanner includes a projector, a camera, and a processor, the projector projecting a first pattern of light on a first point during first intervals and a no light during second intervals, the camera including an optical detector, a first accumulator, and a second accumulator, the optical detector receiving reflected light from the first point, the first and second accumulators summing signals from the optical detector during the first and second intervals, respectively, the processor determining 3D coordinates of the first point based at least in part on the first pattern, the summed signals from the first and second accumulators, and a speed of light in air.
