Abstract: A disposable sensor device for remote sensing of conditions such as temperature and dangerous gasses includes a body defining an enclosed chamber, a power source mounted in the chamber, an on-off switch mounted on and accessible from outside the body, a processor mounted in the chamber and powered by the power source, sensors mounted on the exterior of the body in communication with the processor and capable of detecting gasses and temperature. A transceiver, a speaker, and a microphone are mounted in the chamber and in communication with the processor. The transceiver is adapted to receive sound signals from a remote unit and input the signals to the speaker for broadcast, and the microphone is adapted to receive sound signals from outside the body and input the received sound signals to the processor for transmittal to the remote unit.

Abstract: An assembly for displaying three-dimensional images includes a base portion forming a housing adapted to house electronics and mechanics, and having a planar surface, a projection member disposed in a position removed from the base portion planar surface, drive rods extending from the base portion and connected to the projection member covered by a layer to mask/reveal selectable pixels, the drive rods being movable by electronics and mechanics disposed in the base portion to move the projection member through planes parallel to the base portion planar surface, and a transparent envelope enclosing the base portion planar surface, the drive rods, and the projection member, the envelope being adapted to contain a near vacuum therein.

Abstract: A disposable radio communication device includes a body defining an enclosed chamber, a power source mounted in the chamber, an on-off switch mounted on the body and accessible from outside the body, a processor mounted in the chamber and powered by the power source, and a transceiver mounted in the chamber and in communication with the processor. A speaker is mounted in the chamber in communication with the processor. A microphone is mounted in the body and is in communication with the processor. The transceiver is adapted to receive sound signals from a remote unit and input the signals to the speaker for broadcast, and the microphone is adapted to receive sound signals from outside the body and input the received sound signals to the processor for transmittal by the transceiver to the remote unit.

Abstract: The invention as disclosed is a recoverable tethered optical fiber buoy and winch assembly that is mounted to the back of the sail or the back of an aft non-moving surface of an underwater vehicle and housed in a configuration to provide very little additional drag to the underwater vehicle when the assembly is not deployed. The invention provides a capability to connect ocean surface visual or radio frequency sensors to an underwater mobile platform with a very high data rate link that is retrievable.

Abstract: A method and apparatus is described for enabling a single sensor to indicate a greater quantity of information about a sensed event, or the occurrence of many different types of events. A sensor system employs a number of individual sensors with single-use indication means (such as an explosive charge). Each individual sensor is equipped with a chronometer. The sensors are programmed to transmit information through their single-use indication means at specific times with each specific time being indicative of a particular type of event or of specific information about an event. A central monitor chronologically records all sensor indications and compares indication times to a schedule of time keyed information to determine the nature of each sensor indication.
