Abstract: Disclosed herein is a wireless interactive presentation system that operate in cooperation with a host computer system executing PC compatible application programs capable of generating and displaying text, image and graphic content on a projector or presentation device. The wireless interactive presentation system also includes a wireless data transceiver capable of communicating and exchanging application or system commands and data with a network-based computer system. The wireless interactive presentation system comprises a micro-controller, an infrared receiver and a wireless transceiver to provide short-range communication between the remote system and wireless interactive presentation system. The microcontroller of the wireless interactive presentation system executes a control program to process the commands and data received from remote computer via the wireless transceiver and provides the resultant application window, template, or graphical display data to projector or presentation device.

Abstract: A pendent assembly is disclosed for suspending from a hospital room ceiling to provide various services used in a hospital operating room. The pendent has a distribution head with outlets for such services, including, for example, electrical, gas and vacuum outlets and which is moveable upwardly and downwardly through a motive means operated by personnel using the pendant. An automatic stop mechanism is included and which comprises one or more sets of electrical contacts interposed between upper and lower housings in the distribution head. The lower housing is suspended from the upper housing at a predetermined distance therefrom and is moveable over that predetermined distance with respect to the upper housing. When the distribution head is lowered such that it encounters an obstruction, the lower head is forced upwardly and the contacts between the housings contact each other to complete an electrical circuit.

Abstract: (U) A dual gate tracker and method for controlling the flight path of a missile having television camera in the nose thereof. The two gates respectively track the right and left contrast edges of the target within the field of view of the camera and the target center is determined from a combination of these two signals. The deviation of the determined target center from the center of the field of view of the camer is utilized for missile control. Means are provided to prevent the tracking of the same contrast edge by the two gates and manual control of the gates may be established to position and/or enlarge the gates for target acquisition.
