Patent number: 9097814Abstract: A photoelectric sensor comprises a control unit which is configured to store in a memory data on the amount of received light input from a light-receiving unit or measurement data obtained by a measuring process, and to perform a sampling process in which the data stored in the memory are read at fixed intervals as sampling data, the sampling process being performed within a limited reading period. Further, the control unit outputs the thus read sampling data so as to correspond to the order in which they are stored in the memory.Type: GrantFiled: February 8, 2011Date of Patent: August 4, 2015Assignee: OMRON CORPORATIONInventors: Hideyoshi Nakamura, Atsushi Iwamoto, Koji Kosaka

Patent number: 8805643Abstract: Teaching processing using a model of a workpiece is performed by accepting at least one input of a target value for a response time and a tolerance value for a detection error as a parameter representing a condition for a displacement sensor to operate. A CPU during teaching processing determines a maximum exposure time while it causes repeated detection processing by a light projecting unit and a light receiving unit, calculates variation in measurement data of an amount of displacement, and derives the number of pieces of data of moving average calculation suitable for a value for the input parameter as a result of operation processing using the maximum exposure time and variation in measurement data. This number of pieces of data is registered in a memory and used for moving average calculation in a normal operation mode.Type: GrantFiled: June 13, 2012Date of Patent: August 12, 2014Assignee: Omron CorporationInventors: Hiroaki Takimasa, Yusuke Iida, Hideyoshi Nakamura, Hoshibumi Ichiyanagi

Patent number: 8583404Abstract: A photoelectric sensor comprises a control unit which performs a measuring process for data on an amount of light input from a light-receiving unit. The control unit measures the length TPS of period (from point a to point d) from when measurement data starts to change in the direction of a threshold P0 to when the amount of received light returns to the level at which the measurement data started to change, and the length TON of period (from point b to point c) for which the detection signal is ON-level. The control unit then outputs information on a margin for TPS with respect to TON on a display unit provided for the photoelectric sensor or to an external device in order to display them.Type: GrantFiled: February 8, 2011Date of Patent: November 12, 2013Assignee: OMRON CorporationInventors: Hideyoshi Nakamura, Atsushi Iwamoto, Koji Kosaka, Susumu Mizuhara
