    Abstract: A measuring device includes a total internal reflection prism having a total reflection plane that an object to be measured contacts, a light source to emit light to make the light having a wavelength equal to or greater than 7 micrometers (?m) and equal to or less than 12 ?m incident on the total reflection plane, and a sensor to detect light intensity of the light reflected by the total reflection plane. In the measuring device, an equation arc ? sin ? ( n ? 2 n ? 1 ) < ? ? c < arc ? sin ? ( n ? 2 n ? 1 ) + 5. [ DEG ] is satisfied, where n1 denotes a refractive index of a base material of the total internal reflection prism for the light having a wavelength of 10 ?m, n2 denotes a refractive index of the object to be measured for the light having the wavelength of 10 ?m and n2 takes a value 1.32 or 1.44, and ?c denotes an incident angle of a center of light flux emitted from the light source.

  • Publication number: 20240125691
    Abstract: A biological information measuring technique with improved reliability is proposed. A method of measuring biological information using an optical element with a totally reflecting surface, which is to be brought into contact with an object to be observed, is provided. The method includes, after the optical element has been in contact with the object to be observed, acquiring an absorbance at the totally reflecting surface in a state where the optical element is not in contact with the object to be observed, and determining by an information processing apparatus whether the object to be observed needs to be cleaned, based on the absorbance.

  • Publication number: 20230121849
    Abstract: A tool system includes a portable tool, an image capturing unit, and a control unit. The tool includes a driving unit to be activated with power supplied from a power source. The image capturing unit is provided for the tool and generates a captured image. The control unit controls the tool based on the captured image. The control unit has a work support capability. The work support capability is the capability of placing a restriction on operation of the tool when a work target identified based on the captured image does not conform to a working instruction defined by a working procedure. The control unit suspends, when finding a lifting condition satisfied while performing work-support-enabled operation, the work-support-enabled operation and thereby lifts the restriction on the operation of the tool.
