Abstract: A method to aid the treatment of sleeping disorders that are aggravated by an insomniac's underestimation of total sleep time and sleep efficiency, and overestimation of time necessary to fall asleep. The method includes an observation of the beginning of rest time and self-actuated measurement of the time necessary to fall asleep. The insomniac is made aware of the elapsed wake time and total sleep time upon wakening by further observing the time of awaking and the elapsed wake time as recorded on a wrist watch or other device. The apparatus can include a wrist mounted timer with a hand mounted actuator that stops timing when the insomniac falls asleep and disengages contact with the actuator.

Abstract: High frequency current application electrodes are brought into contact with both hands, both feet, etc., which are extreme parts of a body in order to apply current to the parts of the body to be measured. Potential difference measuring electrodes are brought into contact with the parts to be measured along the path of the high frequency current. High frequency current application electrodes and potential difference measuring electrodes are selected to select the path of the high frequency current and the path of the potential difference measurement in accordance with the purpose. Impedance on each of the parts of the body is measured and body composition is derived.

Abstract: Apparatus and method for the early detection of increased performance impairment, incapacitation or drowsiness of a person, particularly of a person gripping an object such as a steering wheel. A wrist band is worn by the person and an electrical sensor is pressed against the person's skin by the band to sense physiological conditions by detecting various parameters at the wrist and analyzing them to provide an indication of the onset of drowsiness in the person. Some of the parameters analyzed include EMG, temperature, response to stimulation and muscular activity at the wrist. A description of a shock-absorbing wrist monitor is disclosed.

Abstract: An electrode structure for measuring an ECG signal on a person's skin. The electrode structure (100) to be arranged on the person's finger (102) comprises an inner surface (116) residing against the finger (102), which inner surface (1 16) of the electrode structure (100) comprises an inner surface electrode (118), the electrode structure (100) further comprising an outer surface (120) opposite to the inner surface (116), which outer surface (120) of the electrode structure (100) comprises an outer surface electrode (122) to be arranged against a point on the person's skin other than said finger (102) having the electrode structure (100) arranged thereon, the electrode structure being arranged to measure a potential difference caused by the ECG signal between a first electrode and a second electrode.

Abstract: A head acupuncture instrument is disclosed. The head acupuncture instrument includes headgear with electrode probes mounted thereon, a wire dispenser, a plurality of wires extending from an electricity supply to the electrode probes via the wire dispenser, and a column with a bottom end secured to the headgear and a top end extensively received in the wire dispenser. The electrode probes offer stimulating current to acupuncture points needed to be stimulated in a patient's head.

Abstract: A medical extravasation device has an electrode patch that can attach to the skin for sensing electrical information. Tissue impedance is calculated from the electrode patch signals. The patch has elongate pick-up electrodes inboard of elongate energizing electrodes. The measuring zone determined by the elongate space between the pick-up electrodes enhances sensitivity and specificity. The presence of an extravasation is determined by interpreting the tissue impedance measurement. The method for determining the extravasation includes a first step of determining a pre-injection baseline measurement of the tissue impedance. Then, the tissue impedance is monitored during the procedure itself. A predetermined amount of change in tissue impedance is determined to indicate an extravasation.

Abstract: The multi-purpose sensor includes a pair of arms, light-emitting device and light-receiving device that are fitted in an end portion of the arms, respectively, and electrodes that are made of an electrically conductive elastic material and which are bonded to end portion of the arms, respectively.
