Abstract: A system for real-time visualization of subdermal structures of a mammal, using near-infrared (nIR) illumination source, a support structure with independently articulating arms for attaching a camera and a visual display screen, a controller for the camera and nIR illumination source. The camera includes a zoom lens that provides a detection field of view at a long working distance to avoid the camera obstructing the view of the medical personnel when performing a medical procedure on the mammalian body part. A targeting system indicates a focus location of the zoom lens and a center of detection field of view. An nIR bandpass filter and image processor convert the captured and filtered trans-illuminating nIR light to an image signal. An interfaced computer can operate on a commercial or proprietary operating systems and operates image enhancement software and image archival, distribution and display.

Abstract: This invention relates to a trolling propeller in connection with an inboard-outboard type of boat in which the improvement consists of mounting the trolling propeller onto the main propeller assembly without requiring any adjustment of the relative positions of the main and trolling propellers with respect to the boat and in utilizing the main power source to drive a main propeller or to drive the trolling propeller.
