Abstract: A method and apparatus to identify an object include extracting first location information, second location information, and motion information of an object from a polarimetric RADAR signal that is reflected from the object. Each of the first location information, the second location information, and the motion information correspond to each of polarized waves. The apparatus and the method also include generating a first image and a second image, combining the first image and the second image to generate first composite images, each corresponding to each of the polarized waves, and identifying the object using a neural network based on the first composite images. The first image corresponds to each of the polarized waves and includes the first location information and the second location information, and the second image corresponds to each of the polarized waves and includes the first location information and the motion information.

Abstract: A monitor for gases includes a terminal portion that has two states, an output configuration state in which an output signal is sent from the processor to a first device, and an input configuration state in which an input signal is received from a second device.

Abstract: A monitor for gases and a mine includes a housing. The monitor includes a battery disposed in the housing. The monitor includes a gas sensor portion powered by the battery and in electrical communication with the battery which detects a first gas and at least a second gas different from the first gas in the mine. The monitor includes an alarm portion disposed in the housing, powered by the battery and in electrical communication with the battery which emits a visual alert and an audible alert when the gas sensor portion senses that either the first or second gas is above a predetermined threshold. The monitor includes a wireless communication portion disposed in the housing, powered by the battery and in electrical communication with the battery and the sensor portion, which sends a wireless signal from the housing that the gas sensor portion has sensed of either the first or second gas.

Abstract: An electronic device security and tracking system. A system includes one or more clients, wherein the clients are electronic devices; and a server computer system connected to each of the clients, wherein the server computer system is capable of tracking and locating each of the clients. In one aspect, the server computer system includes one or more web servers coupled to each of the clients, wherein the web servers include a website for the electronic device security and tracking system; one or more file transfer protocol servers coupled to each of the web servers; and one or more database servers connected to each of the web servers.

Abstract: An alerting system for fire stations utilizes programmable message centers, zone-coded lighting and audio modules to alert only selected personnel for a particular type of emergency, i.e. fire, medical, etc. to decrease response time while reducing stress to remaining personnel who need not be alerted. Related features include night vision lighting, low level lighting, remote sensing and activation of station doors, ceiling mounted lighting signals, bed proximity audio alerts, automatic control of Emergency Response Facility audio sources and daisy-chain Ethernet cabling for simple installation.

Abstract: An emergency signalling unit which is designed to be carried on the person of a fireman or other worker to alert control personnel should the worker become endangered, and an alarm system which incorporates a plurality of such signalling units, each one worn by a different fireman, for providing an alarm at a central station and an indication of which fireman is in trouble, as well as a means of locating him. The emergency signalling unit includes a radio transmitter, a high intensity strobe lamp, and an audio frequency generator. The alarm system includes a plurality of the above-mentioned radio transmitters, each transmitting on a different carrier frequency, and a receiver at a central control station exterior to the burning building, which is equipped to identify the respective carrier signals and to provide a visual indication of which fireman is in trouble as well as an audible signal to alert control personnel to the existence of an alarm condition.
