There is provided a low-cost electronic control unit that is capable of performing its hardware check every start and stop of the electronic control unit. A monitoring and control circuit section that is an integrated circuit element built in the electronic control unit includes a self-test circuit configured with a built-in self-test control block, scan chain circuits and mask circuitry, and performs a self-test using the built-in self-test control block and a partial combination of the scan chain circuits at start of the operation. In the shipment inspection of the integrated circuit element alone, an external test is performed by a checker microprocessor using an entire combination of the scan chain circuits. Thus, the electronic control unit of low-cost configuration is capable of performing a scan test by making use of part of the scan chain circuits designed for the component inspection.

The invention discloses a high-resolution universal display screen intelligent control system, which comprises a control unit, at least two transmitting units and at least two groups of receiving units which are sequentially connected. The control unit is provided with a first preset value input end, a video conversion module and a first distribution module, presets the screen body resolution of an LED screen, converts a video file into video signal data, divides the data into at least two groups of data according to the number of the transmitting units, performs batch processing on the data through a video output interface and correspondingly transmits the data to each transmitting unit. Each transmitting unit is provided with a first automatic identification module, a processing module and a second distribution module, automatically identifies the screen body resolution, generates control signal data, divides the data into groups, and transmits the data to each corresponding receiving unit respectively. Each receiving unit controls the LED screen through at least three data output ports. The high-resolution universal display screen intelligent control system intelligently identifies the LED screen body resolution, can control a high-resolution large-area LED screen by only one set of control system, and has the advantages of simple control mode and lower cost.

A system and method for merging multiple connections that share a same class of service into a single virtual circuit (VC) in an Asynchronous Transfer Mode (ATM) network. A queuing apparatus includes multiple connection queues for each of the connections, and further includes a scheduled queue corresponding to a particular class of service, wherein contents of the connection queues are transferred into the scheduled queue before being transmitted on the VC. A reassembly queue control block (RQCB) defines a chain of buffer control blocks for the connection queues. Each buffer control block corresponds to a cell belonging to a packet of a particular connection and includes a next buffer address and a lock bit. The chain of buffer control blocks is transferred to a scheduled queue control block (SQCB) in response the lock bit indicating a last packet cell.

A body-worn motion assisting device (1) comprises a shoulder joint mechanism (5) for assisting the user to move a shoulder joint, an elbow joint mechanism (6) for assisting the user to move an elbow joint, and a control unit (100) having a control circuit for controlling a drive unit (11) of the shoulder joint mechanism (5) and an elbow joint mechanism (6). The control unit (100) controls the drive unit (11) according to the physical quantities and biosignal detected by an angle sensor, a torque sensor, and a biosignal sensor. A control section of the drive unit (11) includes a motor monitoring block for monitoring the operation state of a motor and a motor control block for limiting the drive signal sent to the motor depending on the results of monitoring by the motor monitoring block so that the motor does not become under overload.

A method, system and computer program product for preventing at least in part overloading of a control processor. A network device may comprise at least one network processor and at least one control processor. The control processor may be configured to process slow path packets that are redirected from a network processor to the control processor. The control processor may configure control blocks to determine if the bandwidth for the control processor will be exceeded by the network processor transferring another slow path packet to the control processor. If the control block determines that transmitting the slow path packet would exceed the processing capacity of the control processor, then the control block may generate a result indicating for the network processor to discard the received packet. By discarding packets that exceed the processing capacity of the control processor, overloading of the control processor may at least in part be prevented.

Upon reception of a marker cell indicating a current/reserved switching timing, a system switching control block (280-1) of a first transmission path interface block (270-1) which is a current system in the initial state notifies contents of a read out order table and a read out pointer to a system switching control block (280-2) of the reserved system. After the marker cell is received, a read out block (276-1) for the current system continues to read out cells in accordance with the read out order table and the read out pointer until the marker cell is detected in buffers of all the quality classes. On the other hand, a read out block (276-2) of the reserved system discards cells in accordance with the read out order table and the read out pointer notified to the system switching control block (280-2). When the marker cell is detected in buffers of all the quality classes of the current system, the current/reserved switching is performed.
