摘要： A method and apparatus for dispensing fuel has features to prevent theft of fuel and also control maintenance of authorized vehicles. The system includes a portable memory unit which remains with each vehicle. At the fuel dispensing site, a data processing unit receives the portable memory unit to read from it coded information. A central processing unit is located at a central records site and connected to the remote processing unit for record storage. The remote processing unit reads a vehicle identification number and checks it for validity. The remote processing unit also reads a last mileage at which fuel was dispensed, and compares it to a current mileage entered by the operator into the remote processing unit. A next service mileage is also read by the remote processing unit and compared to the current mileage. If the current mileage is less than the last mileage, this is an indication of error, and fuel will not be dispensed. If the current mileage exceeds a next sevice mileage, the operator is notified to immediately take the vehicle to a maintenance facility for maintenance. The portable memory unit may be updated in the field with the remote processing unit to indicate a new current mileage. The memory unit can also be updated at the maintenance site to indicate a new service mileage.

摘要： A method for dispensing fuel has features to prevent theft of fuel and also control maintenance of authorized vehicles. The system includes a portable memory unit which remains with each vehicle. The portable memory unit is removably connected to an on-board computer on the vehicle. The on-board computer senses certain vehicle conditions and changes through transducers carburetor settings. The on-board computer also writes into the portable memory unit a warning if any of the vehicle conditions exceed limits. At the fuel dispensing site, a data processing unit receives the portable memory unit to read from it coded information. A central processing unit is located at a central records site and connected to the remote processing unit for record storage. The remote processing unit reads from the portable memory unit a last mileage at which fuel was dispensed, and compares it to a current mileage entered by the operator into the remote processing unit. A next service mileage is also read by the remote processing unit and compared to the current mileage. If the current mileage exceeds a next service mileage or if warnings are read by the remote processing unit, the operator is notified to immediately take the vehicle to a maintenance facility for maintenance.
摘要翻译： 用于分配燃料的方法具有防止燃料盗窃并且还控制授权车辆的维护的特征。 该系统包括与每个车辆保持的便携式存储器单元。 便携式存储器单元可移除地连接到车辆上的车载计算机。 车载计算机通过换能器化油器设置感测某些车辆状况和变化。 车载计算机还在便携式存储单元中写入警告，如果任何车辆状况超出限制。 在燃料分配站点，数据处理单元接收便携式存储单元以从其读取编码信息。 中央处理单元位于中央记录站点，并连接到远程处理单元进行记录存储。 远程处理单元从便携式存储器单元读取分配燃料的最后里程，并将其与由操作者输入到远程处理单元的当前里程进行比较。 远程处理单元还读取下一个维修里程，并与当前的里程进行比较。 如果当前里程超过下一个维修里程，或者如果远程处理单元读取警告，则通知操作员立即将车辆带到维护设施进行维护。

摘要： A briefcase contains components capable of sampling air for analysis. For example, air can be introduced into the briefcase through inlet ports and that air can be monitored for components of environmental tobacco smoke. A chemical collection device such as a sorbent tube can collect nicotine, a filter can collect respirable suspended particulate matter, and a chemical detector can monitor carbon monoxide levels. The environmental temperature and barometric pressure of the environment can be monitored also. Data is stored on a microcomputer within the briefcase, and can be transferred to a computer at a later time for data analysis.
