An in vivo potential measurement device includes an insulating member and an amplifier. The insulating member has an electrode. The insulating member is inserted into an organ of a living body such that an outer peripheral face of the insulating member contacts with an inner wall face of the organ at a contact site. The electrode senses electric potential at the contact site. The amplifier amplifies the electric potential to obtain output voltage. The amplifier has input capacitance Cin and input resistance Rin that satisfy Cin/Ce&#x3e;0.1 and 1/(2&#x3c0;fCeRin)&#x3e;0.1, where Ce represents capacitance of the insulating member at the contact site, and f represents frequency of the electric potential at the contact site on the inner wall face. A contact state between the outer peripheral face and the inner wall face is evaluated using the output voltage.

In vivo potential measurement device

An inspection device () includes a light source () projecting excitation light to an inner surface of a container (); an imager () capturing a fluorescence image of fluorescence emitted from a foreign substance in response to the excitation light projected; and a detector () detecting the foreign substance adhering to the inner surface of the container from the fluorescence image captured by the imager. The foreign substance contains a material emitting fluorescence in response to the excitation light projected to the material. The detector includes a calculator () calculating an average brightness value in an inspection target region, and an adjuster () adjusting an image-capturing condition where the fluorescence image is captured such that the average brightness value falls within a preset range.

Inspection device and production management method

A three-dimensional object inspecting device for inspecting a three-dimensional object includes a light source, a detector, an orientation information acquisition component, a three-dimensional shading corrector, and an inspection component. The light source emits light energy toward an inspection region set for the three-dimensional object. The detector detects radiant energy radiated from the inspection region. The orientation information acquisition component acquires orientation information about the light source and the detector with respect to the inspection region. The three-dimensional shading corrector performs three-dimensional shading correction on information corresponding to the radiant energy detected by the detector, based on shape information about the three-dimensional object in the inspection region, the orientation information, and shading correction information for a planar image detected by the detector for each of a plurality of working distances. The inspection component performs an inspection based on the information on which the three-dimensional shading correction has been performed.

Three-dimensional object inspecting device

In an in-vivo signal source detection method, three electrodes are arranged on the circumference of a surface of an living body to surround multiple muscle fibers; a first voltage Vgenerated when a first external resistor is connected to between each electrode and a ground potential and a second voltage V'generated when a second external resistor is connected to between each electrode and the ground potential; and a ratio V/V&#x2032;is calculated from the first voltage Vand the second voltage V&#x2032;, and the position of a signal source in the living body is detected based on three ratios V/V&#x2032;.
