专利汇可以提供Sensing system and device专利检索，专利查询，专利分析的服务。并且A novel device and system are provided for the detection of overheated journals and bearings on a moving vehicle. In one embodiment retroreflective material is propelled to the roadway beneath the vehicle, e.g., a train, to form a target. The target is then exclusively detected by an optical scanner located on a rearward portion of the vehicle.，下面是Sensing system and device专利的具体信息内容。
1. A system for detecting overheated journals or bearings on a moving vehicle comprising a. heat sensing means which is adapted to actuate when a journal or bearing reaches a predetermined temperature, b. target-producing means comprising 1. a housing, and 2. a marker within said housing which is adapted to be displaced from said housing to the roadway to form a visibly detectable target upon the actuation of said heat sensing means, and c. an optical scanning device located on a rearward portion of said vehicle which is adapted to scan the roadway beneath said vehicle and which is further adapted to exclusively detect said target and thereafter produce a warming signal.
2. a marker within said housing which is adapted to be displaced from said housing to the roadway to form a visibly detectable target upon the actuation of said heat sensing means, and c. an optical scanning device located on a rearward portion of said vehicle which is adapted to scan the roadway beneath said vehicle and which is further adapted to exclusively detect said target and thereafter produce a warming signal.
2. A system for detecting overheated journals or bearings on a moving vehicle comprising a. at least one heat sensing device adapted to actuate when a journal or bearing on said vehicle reaches a predetermined temperature; b. a target-producing means comprising
2. a housing,
3. propellant means which is adapted to actuate upon receipt of an electrical current from said source when said hEat sensing device is actuated,
3. The system of claim 2, wherein said source of electrical energy is a battery.
4. The system of claim 2, wherein said propellant means comprises an explosive charge which is adapted to detonate upon receipt of said electrical current.
4. a marker within said housing which is adapted to be displaced from said housing to the roadway to form a visibly detectable target upon the actuation of said propellant means, and c. an optical scanning device located on a rearward portion of said vehicle which is adapted to scan the roadway beneath said vehicle and which is further adapted to exclusively detect said target and thereafter produce a warning signal.
5. The system of claim 2, wherein said marker comprises light-reflecting means.
6. The system of claim 5, wherein said marker comprises fluorescent material.
7. The system of claim 5, wherein said marker comprises retroreflective material.
8. The system of claim 5, wherein said battery is located within said housing and is electrically connected in series between said heat sensing device and said explosive charge.
