A magnetic measuring apparatus includes at least one magnetic sensor, a coil, a driving circuit configured to supply a current to the coil, a conductor electrically connecting the coil and the driving circuit, and a computing device which estimates relative positions of the magnetic sensor and the coil based on a magnetic field generated by the current supplied to the coil and detected by the magnetic sensor. The magnetic sensor has a magnetic detection sensitivity in a particular direction, and the particular direction of the magnetic sensor and a current vector of the current flowing through the conductor are parallel.

Magnetic measuring apparatus

A biological information processing apparatus and a biological information processing system. The biological information processing apparatus includes a setter configured to obtain a plurality of pieces of biological information and to set a reference used for discrimination of the plurality of pieces of biological information based on a feature amount calculated for each of the pieces of biological information, and a calculator configured to perform addition average of, among the obtained plurality of pieces of biological information, pieces of biological information that have been discriminated based on the reference. The biological information processing system includes a biological information detecting apparatus and the biological information processing apparatus.

Biological information processing apparatus and biological information processing system

A biometric apparatus includes a calculation device that processes first time series data from a first measuring device and second time series data from a second measuring device; a display device that displays the time series data; a trigger signal generator that generates one or more trigger signals; and an input unit, wherein the calculation device determines one or more specific intervals of the first time series data based on the one or more trigger signals; configures a classification reference for classifying time series data in the one or more specific intervals using the time series data in a first specific interval using an input signal as a trigger; classifies the second time series data for the one or more specific intervals using a result of classifying the first time series data based on the classification reference; and displays a classification result of the second time series data.

An optical sensor including an abutment part configured to abut one edge of an object to be measured, a wall extending along a side of the object to be measured and having a first opening to pass light emitted to the object to be measured, and a first concave portion formed between the first opening and the abutment part on a side of the wall to position the object to be measured. A paper-type discrimination device including the optical sensor, and a controller configured to discriminate a paper type of the object using the reflection light from the object measured by the optical sensor. An image forming apparatus including the optical sensor or the paper-type discrimination device.

Optical sensor, and devices incorporating the same

An optical sensor including an irradiation system including an irradiation system including a light source unit having a light source, the irradiation system configured to emit a linearly polarized light of a first polarization direction onto a surface of an object, a polarizing optical element disposed on an optical path of the light that is emitted from the irradiation system and reflected by diffuse reflection from an incident plane of the object and configured to separate a linearly polarized light component of a second polarization direction, a first photodetector configured to receive the linearly polarized light component of the second polarization direction separated by the polarizing optical element, and a housing supporting the irradiation system, the polarizing optical element, and the first photodetector, where the light source unit is fixed to the housing in a light emitting direction of the light source unit via space.

Optical sensor, recording medium discrimination device, and image forming apparatus

A sensor device is disclosed, including a database, and a processing apparatus. The database includes, for multiple different first types of objects, a first output data which are output data of an optical system acquired beforehand for each of the first objects in a case in which a surface of one side of the first object is set as the detection surface; and a second output data which are output data of the optical detection system acquired beforehand for each of the first objects in a case in which a surface of an other side opposite to the one side of the first object is set as the detection surface. The processing apparatus matches measurement data with the database, the measurement data being the output data of the optical detection system which is acquired with respect to a second object, and determines a type of the second object.
