摘要： An apparatus for testing respective electrical components in situ within a circuit having a plurality of the electrical components. A power bus is connected between a power source and switching devices operable for conducting test current to respective ones of the electrical components. A comparator circuit includes inputs connected to the power bus and to a reference potential. A processor is programmed to actuate respective switching devices for causing a test current to be conducted from the power bus through a respective component, while sensing any output signal from the comparator circuit corresponding to an increased potential on the power bus indicative of a reduced current flow caused by an open or failed component. An isolating resistor is connected between the power bus and the power supply, and a bypass switch is connected in parallel with the isolating resistor for bypassing the isolating resistor and conducting operating power directly to the power bus, for operating the circuit when testing is not in progress.
摘要翻译：一种用于在具有多个电气部件的电路内原位测试各个电气部件的装置。电源总线连接在电源和可操作用于将测试电流传导到相应的电气部件的开关装置之间。比较器电路包括连接到电源总线和参考电位的输入。处理器被编程为致动相应的开关装置，以使得测试电流从电力总线通过相应的部件传导，同时感测来自比较器电路的任何输出信号，该输出信号对应于电力总线上增加的电位，表示减小的电流由打开或失败的组件引起。在电源总线和电源之间连接一个隔离电阻，旁路开关与隔离电阻并联连接，用于旁路隔离电阻，并将工作电源直接连接到电源总线，用于在不进行测试时操作电路进展。

摘要： An apparatus for storing and monitoring a plurality of articles, including at least one cabinet or carrier having a plurality of receptacles in which the articles are stored. In one application, the apparatus is utilized to maintain a library of magnetic tapes or other storage media associated with a data processing center. Each of the articles is identified by a respective code or volser number, and requests for the articles are received by the system in the form of requests for a particular volser number. In a preferred embodiment, the articles may be randomly stored in any of the receptacles in any of a plurality of carriers. The system includes a polling and searching system operable to identify the carrier in which a requested article is currently stored, and a display system operable to display the carrier's location. A host computer controls the operation of the system, but no central data base is maintained of the coded articles. Instead, their volser numbers and usage histories are stored in respective memories associated with each coded article.
