摘要： In heating and cooling apparatus, molecules of working gas are excited by light irradiation and thereby cooled as the gas flows through a mirrored cooling cell. In a closed loop embodiment, the gas then flows by means of a fan or compressor to a first heat exchanger where heat from the matter being cooled is transferred to the gas; and, then to a second heat exchanger where heat is transferred from the gas to a heat sink. The apparatus may be used either like a heat pump or air conditioner. In an open-end cooling apparatus embodiment, the gas flows from the cooling cell, through the first heat exchanger, and to atmosphere. The light source may be a 10.6 micron laser; or a 9-11 micron electric arc, a hot filament or the Sun. Working gases comprise N2 and C02; exhaust gases of engines or fuel cells; and gases which comprise different molecular composition gases or different isotopic species of the same molecular composition gas.

摘要： An alarm system having motion violation sensors (motion or other presence detectors and door and window switches) can have a potential alarm condition be determined to not be a violation of the secured space in response to an authorization code transmitted by a personal device worn by a user. In one embodiment, the personal device transmits an authorization code periodically to bypass sensors in that room for an interval slightly longer than the period between transmissions. In another embodiment, a request for authorization is transmitted in response to a potential alarm condition, in response to which the device transmits the code. In one embodiment, a single authorization code is changed each time the alarm is disarmed, thereby to prevent recordation and subsequent use thereof. Another embodiment responds to plural authorization codes, such as ID numbers of authorized personnel.
