An electronic device is installed in a machine where there is a possibility in occurrence of vibration or impact. The electronic device includes an acceleration detecting unit detecting acceleration in a predetermined time interval, and an impact determining unit. In a case where it is determined that an acceleration value exceeds a predetermined first threshold value, a second threshold value is calculated based on a maximum value among acceleration values of plural accelerations for a predetermined time interval after the determination. In a case where the number of accelerations where acceleration values exceeds the second threshold value among the plural accelerations is a predetermined number or less, the impact as a single-type impact is determined. In a case where the number exceeds the predetermined number, the impact as a multiple-type impact is determined. Also included is an output unit outputting a signal in a case where the impact is determined as the multiple-type impact.

A serial communication branching device and a serial communication system are provided. The serial communication branching device, which branches a plurality of slaves connected to the master by a daisy chain into a plurality of paths, is equipped with a first communication circuit that carries out communication with the master connected to a preceding stage side, a plurality of second communication circuits that carry out communication with the slaves of the paths connected to a subsequent stage side, and a path selection circuit disposed between the first communication circuit and the second communication circuits. In the case that a slave connected on the subsequent stage side transmits a reply signal to the master responsive to a transmission signal transmitted from the master, the path selection circuit selects a path of the slave that transmits the reply signal, and outputs the reply signal from the selected path to the master.

An automated robotic assembly system is configured to assemble a device by fitting a first component made of a material liable to deformation by external force with a second component by means of a robot, and the first component is provided with a distortion detection unit for detecting distortion thereof. If the distortion detected by the distortion detection unit exceeds a predetermined value, a signal for notifying abnormality is output to stop an automated assembly operation by the robot.

Automated robotic assembly system

A remote diagnostic device for a computer-controlled apparatus is provided with a camera configured to pick up an image on a display screen of the computer-controlled apparatus, a diagnostic computer installed in a remote place, and a signal conversion adapter. The signal conversion adapter transmits the image picked up by the camera to the diagnostic computer through a network communication line, automatically identifies an actuator of the computer-controlled apparatus, and converts a remote control signal received from the diagnostic computer into an input/output signal for the actuator and outputs the signal to the computer-controlled apparatus.
