Abstract: A biometric information processing device (1) includes a brain wave detecting unit (10), a control unit (20), and a movement assisting unit (30). The brain wave detecting unit (10) detects biometric information in at least one brain region from among a plurality of brain regions that are selectable in accordance with a body part that is a target of function recovery or function improvement. The control unit (20) determines, based on the detected biometric information, at least one activity state in the brain including the location of the brain region(s) that is (are) activated in a subject while attempting to move the body part, and an activation level of such activated brain region(s). When the control unit (20) determines that the at least one activated state of the brain satisfies a predetermined condition, the movement assisting unit (30) executes a predetermined motion to assist movement of the body part.

Abstract: A sensor for use in detecting cardiopulmonary functions employs a skin-heating conductive surface for use in achieving vasodilitation for the measurement of PO.sub.2 and PCO.sub.2. The same surface is employed as an electrode for a heartbeat and/or respiration rate measuring device.

Abstract: A leakage current detector includes conductive inner and outer housing structures separated by an insulator, with the circuit or equipment under observation being disposed within the inner housing. A current detecting circuit connects the two housings and measures the current therebetween.

Abstract: A transcutaneous gas measuring assembly is described in which a glass electrode is formed by a body of highly insulating material and a bottom by a glass membrane. The membrane is provided with a conductive layer on the inner surface thereof and a preamplifier is disposed within the glass electrode and electrically connected to the conductive layer. A reference electrode is disposed around the glass electrode. All of the above form a measuring portion of the gas measuring assembly.

Abstract: A PH electrode is provided with an ISFET for generating a potential difference according to the PH value of an electrolyte to be measured, and includes a cell for driving the ISFET, so that the PH electrode can be used, as it is, with a conventional, potential difference type PH meter.

Abstract: The grounding of an electrical apparatus is monitored by a primary circuit which is inductively coupled to a coil connected in series between the grounding line of the power cord and a grounding terminal on the electrical apparatus to which a second grounding line is connected.
