Abstract: A semen collection sheet has a front surface to which semen attaches and a back surface having a fixing portion, and when the sheet is unfolded, a reservoir portion is formed to accumulate semen that attaches to the front surface. In a clinic, at home, or other appropriate environment, a user unfolds the semen collection sheet and fixes the sheet to a mounting surface such that the reservoir portion is positioned vertically downward. A user ejaculates aiming at a target portion. Ejaculate semen attaches to the front surface and runs down along the front surface under gravity, and accumulates in the reservoir portion.

Abstract: An optical distance measuring sensor includes a charge accumulation unit for generating a pulse current to be supplied to a light-emitting element; a setting unit that sets a target sensitivity; a pulse current controller that generates the pulse current in synchronization with a repetitive signal, pulse-drives the light-emitting element, and adjusts the pulse current based on the target sensitivity; a light-receiving element that receives the reflected light; a nonvolatile memory having characteristic data of the individual light-receiving element stored therein; a light-receiving element controller that adjusts a multiplication factor of the light-receiving element based on a temperature measured by a temperature sensor, the characteristic data, and the target sensitivity; and a calculation unit that calculates a time from when light is emitted to an object to when reflected light is received based on an output signal repeatedly obtained from the light-receiving element in which the multiplication factor ha

Abstract: To provide a sensor device (100) capable of more accurately detecting a target using rough measurement and fine measurement.

Abstract: A detection system includes a detection device and a display device. The detection device includes a light projecting unit that projects light to a detection object, a light receiving unit that receives reflection light of the light, a light reception quantity acquiring unit that acquires a light reception quantity, and a distance acquiring unit that acquires a distance between a position at which the light is reflected and the detection object. The control device includes a setting unit that sets a threshold value range which is a combination of a threshold value of the light reception quantity and a threshold value of the distance, a detector that detects the detection object based on whether the light reception quantity and the distance belong to the threshold value range, and a display unit that displays correspondence information in which the light reception quantity and the distance are related to each other.

Abstract: Provided are an optical sensor and a detection method which can suppress an influence of an ambient light to detect a target. An optical sensor which detect a target includes: a light reception portion, in which multiple pixels respectively receive lights and a light reception distribution signal showing a light reception amount of each pixel is obtained; an A/D conversion portion, which converts the light reception distribution signal to a digital signal for each pixel; an integration portion, which integrates multiple converted light reception distribution signals for each pixel; and a determination portion, which determines the presence or absence of the target based on the integrated light reception distribution signal.
