Abstract: A system control apparatus and a system control method in which, when a state of a production system is maintained at a reference value or within a reference range, a state of the production system is surely controlled while generation of useless energy is avoided and a user can recognize a degree of energy saving. In consideration of an influence of a disturbance, a prediction range is derived with respect to data (“status data”) indicating the state in which quality of a product produced by the production system, and an instrument is controlled based on a relationship between the prediction range and the reference value. Therefore, the instrument can be controlled in consideration of a variation in status data due to the influence of the disturbance.

Abstract: A safety control system is provided, which is capable of monitoring many more drive circuits by using a single controller without modifying the configurations of the controller and the drive circuit. An a-contact of a relay is electrically connected between a FB (feedback) output terminal and a FB input terminal of a safety controller. A b-contact of the relay is electrically connected between a signal output terminal (safety output (1) terminal) of the safety controller and a signal input terminal (safety input (1) terminal) of a safety drive circuit. A coil of the relay is connected to a FB monitor output terminal of the safety drive circuit. No factor in a large voltage drop is present between the FB output terminal and the FB input terminal, thus making it possible to monitor many more drive circuits by using a single controller.

The power conditioner alternately turns on and off both switches in the first group at a prescribed chopping frequency and alternately turns on and off both switches in the second group at a PWM frequency higher than the chopping frequency. If control is performed with a dead-time provided in the on/off timing for both switches in each group, the power conditioner adjusts and controls the on/off duty for the second group switches to correspond to the effective on drive in one switch by each diode during the dead-time for each switch in the first group.

Abstract: A switch is provided with a reset function including a heart cam portion which extends from a locked position to a side where a lock pin operation end biases, and a lock release passage IV which is blocked off by a lock pin retention protrusion during being retained.

This embodiment can decrease wear between the lock pin and the member for retaining the lock pin.

Abstract: According to one aspect of the teachings presented herein, a projective volume monitoring apparatus is configured to detect objects intruding into a monitoring zone. The projective volume monitoring apparatus is configured to detect the intrusion of objects of a minimum object size relative to a protection boundary, based on an advantageous processing technique that represents range pixels obtained from stereo correlation processing in spherical coordinates and maps those range pixels to a two-dimensional histogram that is defined over the projective coordinate space associated with capturing the stereo images used in correlation processing. The histogram quantizes the horizontal and vertical solid angle ranges of the projective coordinate space into a grid of cells. The apparatus flags range pixels that are within the protection boundary and accumulates them into corresponding cells of the histogram, and then performs clustering on the histogram cells to detect object intrusions.

Abstract: Enabling height recognition processing by setting a height of an arbitrary plane to zero for convenience of the recognition processing. A parameter for three-dimensional measurement is calculated and registered through calibration and, thereafter, an image pickup with a stereo camera is performed on a plane desired to be recognized as having a height of zero in actual recognition processing. Three-dimensional measurement using the registered parameter is performed on characteristic patterns (marks m1, m2 and m3) included in this plane. Based on a positional relationship between a plane defined as having a height of zero through the calibration and the plane expressed by the calculation equation, a transformation parameter (a homogeneous transformation matrix) for displacing points in the former plane into the latter plane is determined, and the registered parameter is changed using the transformation parameter.
