摘要： PROBLEM TO BE SOLVED: To provide a distance measuring means having high measuring speed and measurement accuracy.
SOLUTION: A sensor for measuring distances or changes in distance according to the principle of signal transmit time includes a transmitter a transmitter controller capable of transmitting transmitter signals at a transmission time which can be previously set and a receiver for receiving reflected signals. An evaluation unit of the sensor transmits a signal at some transmission time at every measuring period, scans receiving signals, creates a histogram 114b by accumulating signals received in this way over a large number of measuring periods, and determines the time of reception and the passage time on the basis of the histogram 114b. The evaluation unit is constituted in such a way as to determine the time of reception with time resolution higher than the time resolution of the histogram 114b by interpolation and previously set the time of reception over the large number of measuring periods according to some distribution so that the temporal position of the time of reception in the histogram 114b may change over the large number of measuring periods.

摘要： PROBLEM TO BE SOLVED: To increase the efficiency of an operation for fixing an end part cap to a hollow molded body. SOLUTION: This non-contact type protective device (particularly, an optical grid) comprises a light emitting unit and/or a light receiving unit stored in a case formed as the hollow molded body 2. At least one end face of the hollow molded body 2 is closed by an end part cap 4. When the end cap 4 is fitted to the hollow molded body 2 and fixing pins 17 are inserted into positioning holes 16 and 42 from one side face (side on which a cover plate 5 forming a light emitting face and/or a light receiving face) of the hollow molded body 2, the end part cap 4 is fixed to the hollow molded body 2. Thus, as compared with a method for fixing the end part cap 4 with a plurality of screws, not only the operation can be easily performed but also the protective device can be manufactured at lower cost because a screw hole must not be formed in the hollow molded body 2.

摘要： PROBLEM TO BE SOLVED: To provide method and device for controlling at least one safety- related function (an emergency stop function, for instance) of a machine. SOLUTION: A monitoring region 18 is monitored with at least a sensor having location resolution and/or time resolution. By using the sensor, position, moving direction and/or moving speed v of a person 26 are recognized. A safety boundary 32 or a safety region 38 separates off a danger region 36 and defines a safety distance S up to the machine. When an object advances into the safety region 36, the safety-specific function is operated. The position of the safety 32 and/or the size of the safety region 38 are set to be variable according to circumstances by depending on the position, the moving direction and/or the moving speed v.

摘要： PROBLEM TO BE SOLVED: To recognize the presence of an article with no recognizable code in a read area. SOLUTION: The scanning device 11 sends a light beam for scanning movement into the read area provided at a read distance L. The read area has a flat front surface 13 and specific depth. An article 16 carrying an optically detectable article code 15 moves through the read area and an electronic evaluation system 17 provided at the output end of the scanning device evaluates an electric signal generated by a photoreceiver array 19 from light reflected on the scanning device from the code to discriminate the article code. A light reflecting means 18 is arranged behind the read area and reflects the light received from the scanning device when the article 16 is not present in the read area. The electronic evaluation system is equipped with an article recognizing means 21 and inhibits the article discrimination until light whose arrival from the reflecting means 18 can be discriminated is not received.
