摘要： A control unit is disclosed for controlling the usage of an electrical device, such as a television. The control unit maintains a plurality of time accounts for a plurality of users. The control unit, responsive to receiving a request to operate the electrical device from a user, identifies a time account for the user and begins decrementing time from the time account for the user when the electrical device is turned on. The control unit decrements time from the time account based on one or more desired algorithms. The algorithms as disclosed herein cause the control unit to continue decrementing time from the time account of the user even after the electrical device is shut off.

摘要： An exemplary coil actuator for an associated switching device which can be actuated during its operation from an open position to a closed position to allow a current to flow therethrough and from the closed position to the open position to interrupt such flowing from flowing therethrough. The coil actuator includes a coil electromagnet arranged to move between a rest position and an actuating position, wherein movement from the rest position to the actuating position is suitable to cause the actuation of the switching device; and an electronic component arranged to count an operation time which is indicative of the duration of the actuation of the switching device.

摘要： A machine includes first and second electrically actuated components and a shutdown circuit electrically interconnected therewith. The shutdown circuit has a current sense relay element which is electrically connected to the first electrically actuated machine component. The current sense relay element includes a coil capable of generating a magnetic field in response to direct current flowing therethrough and a reed switch adjacent the coil which is movable between open and closed positions in response to the presence of the magnetic field. The reed switch is normally closed when the direct current flowing to the first electrically actuated machine component is at or above a predetermined level. The reed switch opens when the direct current flowing to the first electrically actuated machine component falls below the predetermined level. The shutdown circuit also includes a shutdown relay element electrically connected to the current sense relay element and the second electrically actuated machine component so that when the direct current flow falls below the predetermined level, the current sense relay element the shutdown relay element are opened and the first and second electrically actuated machine components are shutdown.
