Abstract: Recording a history related to an operation of a safety program contributes to a determination of a cause of a false OFF signal. A safety controller acquires, from at least one safety input device or safety sensor, extra information that is not used for obtaining an output signal and records an input signal and an output signal together with the extra information as history information at predetermined recording intervals.

Abstract: To make it possible to determine in advance the propriety of a measure by simulating a change of an objective variable due to a change of a value of a feature value. A prediction model for predicting an objective variable is generated based on feature values of a plurality of attributes included in analysis target data. An adjustment of a representative value of a feature value is received based on a user's operation input. The feature values of the plurality of attributes are changed according to adjustment amount of the representative value, and the numeric value of the objective variable is recalculated from the prediction model and displayed on a monitor.

Abstract: The present invention provides a mechanism for adding a disabling function that satisfies a safety standard to a safety program in a simplified procedure. A program creation assistance device that assists in creation of a safety program to be executed by a safety controller creates a safety program including an input block to which a safety input signal from an input device is assigned, a functional block that implements a safety function, and an output block that outputs a safety output signal, and adds, to the safety program created, a plurality blocks and connections between the plurality of blocks in accordance with an instruction from a user, the plurality of blocks and the connections between the plurality of blocks being configured to implement a disabling function that disables the safety input signal when a predetermined condition is satisfied in the safety program.

Abstract: To make it possible to automatically generate an objective variable so that even those who are unskilled in data processing can freely conduct an analysis. It is recognized whether a type of an attribute value of each attribute of analysis target data is a numeric type indicating that it is a numeric value or a category type indicating that it is a category. At least one attribute that is a numeric type is set as an attribute of an aggregation target, at least one attribute that is a category type is set as an attribute of an aggregation unit, and for each category value of the attribute of the aggregation unit, a numeric value of the attribute of the aggregation target is aggregated based on a previously prepared aggregation function to generate a new objective variable candidate.

Abstract: A sufficient decoding processing time for each image acquired by performing high-speed imaging is secured to obtain a stable reading result, thereby enabling immediate output of the obtained reading result. A processing unit has a first core and a plurality of second cores. The first core instructs the second cores, presumed to be capable of immediately executing the decoding process or executing the decoding process next to a decoding process being currently executed, to execute the decoding process. The second cores are configured to be capable of simultaneously executing the decoding process on read images instructed by the first core at different timings.

Abstract: To miniaturize an illumination device while meeting requirements of angle characteristics of a liquid crystal panel. A light source 31b is arranged above an outer end portion side of a liquid crystal panel 31d that is positioned radially outward of an illumination housing. A relative position between the liquid crystal panel 31d and the light source 31b is set such that light emitted from the light source 31b is incident within an effective angle range of the liquid crystal panel 31d.

Abstract: A PLC collects a device value stored in any one of a plurality of devices and stores information relating to collecting time at which the device value is collected and the device value in association with each other in a first buffer. The PLC collects data input from a monitoring apparatus and stores information relating to acquiring time at which the data is acquired and the data in association with each other in a second buffer. A saving section saves, when a predetermined saving condition is satisfied, the device value and the information relating to the collecting time stored in the first buffer, and the data and the information relating to the acquiring time stored in the second buffer in correspondence with each other.

Abstract: An imaging processing part 131 executes first imaging processing of causing a first illuminating part to emit structured light from a first direction to a measurement target, causing an imaging part 120 to generate image data, and causing a buffer memory 133 to store therein the generated image data. A computing processing part 132 executes first computing processing of generating, height data corresponding to the first direction. Concurrently with the first computing processing, the imaging processing part 131 executes second imaging processing of causing the second illuminating part to emit structured light from a second direction to the measurement target, causing the imaging part 120 to generate image data, and causing a buffer memory 134 to store therein the generated image data. The computing processing part 132 executes second computing processing of generating height data corresponding to the second direction.

Abstract: Provided is a displacement sensor having a modular structure that allows further downsizing. A housing of a head is made up of a main housing and a lid member, both of which are precision molded products made of a metal material. A first holder to which a light projector is bonded and a second holder to which a light receiver is bonded are individually positioned on and bonded to the lid member. This work is performed by a mounting device. Optical components such as a light projecting lens are also bonded to the lid member, and the lid member modularized by incorporating such optical components is assembled and welded to the main housing.
