Abstract: A soap bar has a solid or semi-solid matrix comprising a cleaning composition; and one or more articles positioned in the matrix. The articles include an electrical power source, an output device, a switching device, a controller and a pair of electrodes in spaced apart relationship. The pair of electrodes are in electrical communication with the electrical power source and the output device. The output device produces an output when a conductive material creates a current path between the pair of electrodes. A section of the matrix covers the pair of electrodes and prevents the conductive material from creating the current path until the section of the matrix is removed thereby uncovering the pair of electrodes. A sensor device may also be included to create the current path between the pair of electrodes.

Abstract: A railroad signal system interlocking is automatically tested. A control point interface corresponding to a predetermined function of the interlocking has an isolated section and a control section. The isolated section is connected with the interlocking and has a normal, inactivated state during operation of the interlocking, and an activated state for testing the interlocking by detecting an electrical characteristic representing the status of the predetermined function executed by the interlocking. The control section drives the isolated section to its activated state and receiving an output from the isolated section in response to the detected electrical characteristic, and delivers a status report.
