Abstract: A detection system includes an imaging unit configured to acquire in advance a first distance image indicating a background and acquire a second distance image including at least the background and a target object, and a processing unit configured to calculate a first virtual volume indicating the background from the first distance image, calculate a second virtual volume indicating the target object from the second distance image, and compare the first virtual volume with the second virtual volume to detect the target object.

Abstract: A detection system includes an imaging unit configured to acquire a distance image indicating a distance to a target object, and a processing unit configured to divide pixels included in the distance image into blocks according to a distance relationship, and detects a state of the target object by comparing ratios of pixels included in the respective blocks.

Abstract: The present invention provides a grease composition to be used for lubrication between resin-made members or lubrication between a resin-made member and a member made from another material. With respect to the total mass of the composition, more than 0.5 mass % but less than 7.5 mass% of a solid organic molybdenum compound is contained.

Abstract: A method for calculating a tolerable value for simultaneous switching noise in an input/output circuit having a differential input supplied with a power supply voltage. The method includes providing an input/output circuit having a differential input unit with a pulse signal of a predetermined duty ratio, setting a tolerable range for the duty ratio of the output signal of the input/output circuit with respect to the pulse signal, changing the power supply voltage supplied to the differential input unit of the input/output circuit, measuring the duty ratio of the output signal corresponding to the voltage change, comparing the measured duty ratio with the tolerable range, and calculating a tolerable value for the simultaneous switching noise.

Abstract: A method of preparing layout data of patterns formed in a scribe area. First, library data on which a plurality of patterns and arrangement limiting conditions of each pattern and arrangement importance of each pattern are registered is prepared. A pattern to be arranged in the scribe area is selected from the library data. Then, the selected pattern in the scribe area is arranged in accordance with the arrangement limiting conditions and arrangement importance of the selected pattern. In this method, it is not necessary to prepare many arrangement models, so that preparing time of layout data is shortened.
