A wearable device suitable for monitoring blood in a body part may be implemented for instance in oximeters for detecting oxygen level in blood, which operates by contrasting the ratio of transmission of visible red light to transmission of infrared light. The ratio of the amount of absorbed red light to the amount of absorbed infrared light indicates the amount of oxygen in the blood. Therefore, in wearable devices having an oximeter function, there may be an emitter emitting red light to the sensor, and an emitter emitting infrared light to the same sensor which is capable of detecting in both ranges of wavelengths. In this case, the red light emitter and the infrared light emitter take turns to emit light.

Device and method suitable for monitoring arterial blood in a body part

A device for monitoring heart rate or blood oxygen level during exercise is disclosed having sensors () and emitters (), wherein the sensors () are used to monitor transmission from each of the emitters () in turn. This provides a possibility that a smaller device can be provided since less sensors and emitters can be used while obtaining more number of observations. In some embodiments the repeated use of sensors with different emitters introduces redundancy into the device so that the device is more robust and may function even in the event that one or two of the emitters and sensors have broken down.

A device comprising a piece of planar substrate embedded with two sensors and two emitters. The substrate has a generally planar surface for application onto the wearer's body part. The emitters and sensors are shown to be arranged in such a way that no subset of any two emitters and one sensor, or subset of any two emitters and one sensor, forms a straight line, which prevents the two sensors from detecting the same noise caused by the same wearer movements.

An earplug-type earphone is disclosed including: an earplug () for producing sound and an elastic support (). The earplug () includes a front housing () and a rear housing () connected in that order. The elastic support () is positioned on an outer side of the rear housing (). When the earplug () is inserted in the external auditory canal, the elastic support () is pressed and deformed and then applies resilience to the helix, by which the earplug can be stably positioned in the external auditory canal.

A noninvasive light sensor for detecting heart beat signals has a circular support member engageable circumferentially with a body part of a person. There are a plurality of light emitters and light detectors located around a circumference of the circular support member for respectively emitting light signals into different areas of tissue surrounding the body part, and receiving reflected light signals from the different areas of tissue surrounding the body part.

Method of determining body parameters during exercise

A method and apparatus for calibrating or adjusting an accelerometer, wherein the accelerometer is held stationary to obtain the signal outputs from the accelerometer, representing component vectors making up the composite vector of 1 g. Thus, gain or sensitivity, and the zero-g signal offset along for each axis of the accelerometer is determined and adjustable.
