An endoscope includes a housing with a distal end insertable into a cavity; an image capture device at the distal end to obtain 3D images, and process them to form a video signal; and a folded substrate folded into a U-shape having first and second legs. The image capture device includes a detector and a lens system with right and left multi-band pass filters having right pass bands that are complements of left pass bands. The lens system receives the 3D images including right and left images. The detector faces the lens system to obtain the right and left images. A processing circuit faces the proximal end behind the detector to process signals from the detector. The folded substrate includes the detector at an outer side of the first leg facing the lens system and the processing circuit at an outer side of the second leg facing the proximal end.

A Traffic Handheld Control Warning Sign including a first and second display sign which are fastened together and have the capability to display different traffic control warnings and commands simultaneously. The invention is battery powered and can be controlled by a separate or built in remote control. The invention can be hand held or can be used hands free by placing it in a tripod or pole and operating it with a remote control from a distance of up to 40 meters.

Micro-emitter arrays and methods of microfabricating such emitter arrays are provided. The microfabricated emitter arrays incorporate a plurality of emitters with heights greater than 280 microns with uniformity of +/&#x2212;10 microns arranged on a supporting silicon substrate, each emitter comprising an elongated body extending from the top surface of the substrate and incorporating at least one emitter tip on the distal end of the elongated body thereof. The emitters may be disposed on the substrate in an ordered array in an X by Y grid pattern, wherein X and Y can be any number greater than zero. The micro-emitter arrays may utilize a LMIS propellant source including, for example, gallium, indium, bismuth, or tin. The substrate may incorporate at least one through-via providing a fluid pathway for the LMIS propellant to flow from a propellant reservoir beneath the substrate to the top substrate surface whereupon the micro-emitter array is disposed.

A dual objective endoscope for insertion into a cavity of a body for providing a stereoscopic image of a region of interest inside of the body including an imaging device at the distal end for obtaining optical images of the region of interest (ROI), and processing the optical images for forming video signals for wired and/or wireless transmission and display of 3D images on a rendering device. The imaging device includes a focal plane detector array (FPA) for obtaining the optical images of the ROI, and processing circuits behind the FPA. The processing circuits convert the optical images into the video signals. The imaging device includes right and left pupil for receiving a right and left images through a right and left conjugated multi-band pass filters. Illuminators illuminate the ROI through a multi-band pass filter having three right and three left pass bands that are matched to the right and left conjugated multi-band pass filters. A full color image is collected after three or six sequential illuminations with the red, green and blue lights.
