专利汇可以提供Pressure activated heat absorbing or emitting detection system专利检索,专利查询,专利分析的服务。并且A detector for use in warfare, to provide intelligence information concerning the use of roads or trails by the enemy. The detector comprises an agglomeration of crushable capsules containing reactants for producing a temperature change when the capsules are crushed. The agglomerations are distributed over roads and trails to be monitored and may contain either a chemical which will react with a component of the atmosphere or two chemicals which will react with each other when the agglomerations are crushed. In either case, the reaction produces a change in temperature and a corresponding change in infrared radiation which is detectable by an overflying aircraft carrying suitable infrared detection equipment.,下面是Pressure activated heat absorbing or emitting detection system专利的具体信息内容。

1. The method of covert aerial detection of the movement of relatively heavy objects such as troops or vehicles over an area, comprising the steps of: distributing over the area small camouflaged agglomerations of a large number of pressure frangible capsules containing a chemical reactant capable of reacting exothermally or endothermally with a component of the atmosphere; and later photographing the area with an airborne infrared sensitive camera.
2. The method of covert aerial detection of the movement of relatively heavy objects such as troops or vehicles over an area, comprising the steps of: distributing over the area small camouflaged agglomerations of a large number of uniformly intermixed discrete quantities of the individual reactants of a two-reactant exothermic or endothermic chemical reaction, the quantities of at least one of the reactants being contained in capsules that rupture under pressure; and later photographing the area with an airborne infrared sensitive camera.
3. A pressure activated temperature changing granular material to be spread over the ground to permit the covert aerial infrared detection of troop and vehicle movements in which each grain is a camouflaged agglomeration of a large number of pressure frangible capsules containing a chemical reactant capable of reacting exothermally or endothermally with a component of the atmosphere.
4. A pressure activated temperature changing granular material to be spread over the ground to permit the covert aerial infrared detection of troop and vehicle movements in which each grain is a camouflaged agglomeration of a large number of uniformly intermixed discrete quantites of the individual reactants of a two-reactant exothermic or endothermic chemical reaction, the quantities of at least one of the reactants being contained in capsules that rupture under pressure.
