A biological information detection apparatus includes a detection unit which has a light receiving unit receiving light from a subject, a light transmitting member which is provided on a housing surface side in contact with the subject of the biological information detection apparatus, transmits light from the subject, and comes into contact with the subject when measuring biological information of the subject, and a diaphragm unit which is provided between the light transmitting member and the detection unit, between the light transmitting member and the subject, or inside the light transmitting member, and narrows light from the subject in an optical path between the subject and the detection unit. The detection unit includes a light emitting unit which emits light to the subject, and the biological information detection apparatus has a light shielding unit which is provided between the light receiving unit and the light emitting unit.

A biometric information processing device includes a heart rate detection unit, a relative heart rate calculation unit, a relative oxygen intake calculation unit, an oxygen intake estimation unit and a calorie expenditure calculation unit. The relative heart rate calculation unit calculates a relative heart rate obtained from a first difference over a second difference, the first difference being by subtracting a resting heart rate of the subject from the heart rate, the second difference being by subtracting the resting heart rate from a maximum heart rate. The relative oxygen intake calculation unit calculates a relative oxygen intake based on the relative heart rate. The oxygen intake estimation unit estimates the oxygen intake from the relative oxygen intake. The calorie expenditure calculation unit calculates calorie expenditure based on the oxygen intake.

Biometric information processing device, biometric information processing method, and control program

A biometric information processing device has a heart rate detection unit that detects the heart rate of a subject; a relative heart rate calculation unit that calculates a relative heart rate, which is the relative value of the heart rate to the prescribed resting heart rate of the subject; a relative oxygen intake calculation unit that calculates a relative oxygen intake based on the relative heart rate; an oxygen intake estimation unit that estimates the oxygen intake from the relative oxygen intake; and a calorie expenditure calculation unit that calculates calorie expenditure based on the oxygen intake.

A beat detection device includes: a pulse wave sensor adapted to detect and output a pulse wave signal; a body motion sensor adapted to detect and output a body motion signal due to a body motion of a human body; a pulse wave signal filtering section adapted to generate an adaptive filter based on the body motion signal to extract a noise signal in the pulse wave signal, and to output a beat signal obtained by eliminating the noise signal from the pulse wave signal; and a filter coefficient setting section adapted to set a coefficient of the adaptive filter to be a predetermined value in response to detection of increase in a body motion change beyond a predetermined threshold value based on the body motion signal.

A coil unit includes a planar coil, a printed circuit board that includes a planar coil placement section that receives the planar coil, a protective sheet that is provided on a transmission side of the planar coil and protects the planar coil, and a magnetic sheet that is provided on a non-transmission side of the planar coil. The planar coil is placed in the planar coil placement section and is electrically connected to the printed circuit board. The planar coil placement section has a shape that corresponds to an external shape of the planar coil.

Coil unit, method of manufacturing the same, and electronic instrument

A coil unit includes a planar coil, a magnetic member that is provided under the planar coil, a magnetic flux leakage prevention member that is provided under the magnetic member, and a heat sink that is provided under the magnetic flux leakage prevention member. The magnetic flux leakage prevention member is electrically insulated from the heat sink. The magnetic flux leakage prevention member is insulated from the heat sink using a double-sided adhesive tape, for example. Since the heat sink dissipates heat generated from the planar coil and is electrically insulated from the magnetic flux leakage prevention member, the heat sink does not function as a member which receives a magnetic flux.

Electronic instrument including a coil unit

A deep-area temperature calculating devicecalculates the temperature Tof a deep area on the basis of a first body-surface temperature and second body-surface temperature from body-surface sensorsA andB, and on the basis of a first intermediate temperature and second intermediate temperature from intermediate sensorsA andB. Since the temperature Tof the deep area is determined from two body-surface temperatures and two intermediate temperatures, the temperature Tof the deep area can be calculated regardless of the heat resistance of the thermometer without making any assumptions regarding the heat resistance of the area that extends from the deep area of the human body to the body surface. Thereby, the temperature Tof the deep area can be calculated and the body temperature can be measured with high precision regardless of differences in the body type or contact with clothing or bedding.

Unnecessary operations are eliminated in the calculation of a non-decompression limit at the current water dept. In this manner, the calculation of the non-decompression limit is made more efficient and the required computing time is shorten to the point where the function can be incorporated into a wrist worn device that provides timely data.

Data processing apparatus for divers and a data processing method, program, and recording program storing the same

Provided is a diver's information processing device for notifying a diver of a change in a pressure decrease ratio, at which pressure decreases during surfacing, for the purpose of minimizing the risk of a diver's decompression sickness and excess pulmonary expansion. In particular, when diving is performed at a high altitude, notification is made so that a pressure decrease ratio will be held lower than a pressure decrease ratio permitted at a low altitude. A diver's information processing device includes means that uses a pressure meter and a timer to calculate a pressure decrease ratio. Moreover, the diver's information processing device includes means that uses an acoustic notifier a vibration generator and a display panel to continuously notify a pressure decrease ratio, at which pressure applied to a diver decreases during surfacing, for the purpose of minimizing the dangers of diver's surfacing.
