摘要:
A vehicle sliding door opening/closing control device includes a trouble detecting circuit for detecting a trouble in a control unit which is used for controlling operation of a motor to drive a vehicle sliding door in opening and closing direction, and switching unit responsive to detection of a trouble in the control unit by the trouble detecting circuit for shorting power input terminals of the motor, and after the lapse of a predetermined time, opening the power input terminals of the motor. Upon detection of the trouble in the control unit, the power input terminals of the motor are shorted so that the motor is kept in a locked state. In this instance, if the sliding door is moving at a high speed, it is possible to apply braking to the sliding door. Thereafter, after the lapse of the predetermined time, the switching unit opens the power input terminals of the motor to release a lock on the motor, thereby allowing the sliding door to be displaced by manual.

A document inserter system having an improved control system is disclosed. The system includes a sheet inserter system and one or more web modules for, receiving a web of forms, scanning the forms for information, storing and retransmitting the information, separating the web into discrete forms and feeding the forms for further processing. The information includes control information scanned from a control document for controlling formation of a batch of forms associated with that control document. The control system includes a supervisory control processor which receives the control information and controls the sheet inserter system and the web modules in accordance therewith. The system also includes web control processor systems for direct control of each web module, which web control processor systems are responsive to the supervisory control processor. The system is controlled in accordance with a prespecified configuration which defines the document type for each web module. An operator input is provided whereby an operator may specify a configuration for a mailing. In one embodiment the configuration is specified by interactive selection from a menu displayed by the supervisory control processor. A system and method for orderly shut-down and restart of the inserter system are also disclosed.

An apparatus for shutting-off electrical appliances and electrical devices upon detection of an audible alarm issued by a separate fire alarm. The separate fire alarm device generates an audible warning upon detecting fire. The shutting off device make use of these ever improving ubiquitous fire alarms to greatly reduce the cost and complexity of providing a power shut-off response in the case of fire. The shut-off device includes a switch to interrupt electrical power to an appliance, the switch is activated by a microphone for detecting an audible alarm.

The present invention relates to the provision of a modular control system for a glass forming machine. The glass forming machine control system comprises one central control unit (20) and one machine control unit (22), which are connected via a high-speed data bus (32). The machine control unit (22) is spread out to a plurality of peripheral control units (24, . . . , 30) via a plurality of high-speed data buses (34, . . . , 40). The machine control unit (22) is adapted to distribute control signals received from the central control unit (20) to the peripheral control units (24, . . . , 30) in real time.
摘要:
A microcontroller system includes a microcontroller, a device which is controllable by the microcontroller, and a monitoring device. Under the control of a normal operation program, the microcontroller outputs a normal operation indicating signal. If the normal operation indicating signal is absent, the monitoring device transfers the device into a secured state and, if it is absent over a predefined period of time, locks the device in that state. When predefined exceptional conditions occur, the microcontroller changes to an operation preparation program, and the monitoring device increments a register. If the contents of the register reach a predefined value, the monitoring device locks the device in the secured state.

A multiple error processor in an automatic work handling apparatus includes controlling a number of operating mechanisms individually by the operation of control devices corresponding thereto. The operating mechanisms are controlled to stop for errors arising thereon according to stop mode data which corresponds to the errors. The operating mechanisms are controlled to restart-up according to restart-up data corresponding to a first generated error and also for ensuing errors occurring after the first error and before all of the operating mechanisms come to a stop. The errors are stored in an error code memory in an error recovery device.
