Abstract: A non-invasive method and system for monitoring core body temperature (Tc) of a user continuously so as to prevent the risk of over-heating. The system comprises a detection unit to be worn in the user's ear for measuring physiological data of the user by a plurality of sensors and an analysis unit connected to the detection unit via a communication link for computing Tc of the user with a prediction model using the physiological data measured by the detection unit where the effects of heart rate and external environmental temperature on auditory canal temperature of the user are taken into account. The sensors comprise two sensors (207, 208) for measuring auditory canal temperatures and sensors (209, 210) for measuring heart rate and external auricle temperature respectively. The prediction model is preferably a random forest prediction model or a linear or polynomial regression model. An over-heating state of the user is determined when the computed Tc is above a threshold level (e.g. above 40° C.).

Abstract: 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.

Abstract: An earpiece having light sources and optical sensors arranged to obtain physiological data from the tragus of an ear. At least one extra light source or optical sensor is provided such that there is redundancy. The redundancy allows for misalignment of the earpiece while still having sufficient number of light sources and optical sensors to continuously obtaining physiological data.

Abstract: A device to be inserted into the ear canal having at least two thermistors for observing a temperature gradient in the ear canal of a user. Changes in the temperature gradient are monitored for determining the risk of the user in facing an imminent heat stroke. The device includes a plug suitable for restricting air flow through the opening of the ear canal, a first temperature monitor arranged to measure the temperature of air restricted in the ear canal at a first location in the ear canal, and a second temperature monitor arranged to measure the temperature of air restricted in the ear canal at a second location in the ear canal. The second location being deeper in the ear canal than the first location.

Abstract: Methods and related devices 100 for obtaining the blood pressure of a person in two different ways. The first way comprising steps of providing a light source 101, and an optical sensor 103 configured to detect light from the light source 101 which has propagated through the wrist of a wearer of such a device 100. The amount of light propagating through the wrist depends on the amount of blood in the wrist. Blood pressure is then observed by monitoring the difference in the amplitude of blood pulsation within the wrist when the wrist is lifted above heart level, and when the wrist is lowered below heart level. The second way comprising mathematically analysing light transmission signals though a body part of the same person. Blood pressure readings obtained by the first way are used to calibrate blood pressure readings by the second way.

Abstract: An earpiece comprising a sensor for detecting light in the ear canal. The sensor is held in a cradle to reduce field-of-view. The reduced field-of-view reduce the possibility of light reaching the sensor in a tangential angle. Therefore, the chance of ambient light and light from an emitter reaching the sensor directly is reduced. This improves the likelihood that the readings of the sensor has a greater portion from light that has travelled through the tissue of the ear canal than not.

Abstract: A device having a fingerprint reader and a first heart rate monitor which are co-located such that a person's heart rate is obtained at the same time as this fingerprint. The device is integral to yet another heart rate monitor for monitoring the performance of the person in exercise. The readings of the other heart rate monitor correlates to the readings of the first heart rate monitor if the person whose fingerprint is read is the same person wearing the second heart rate monitor, in which case the fingerprint is deemed acceptable for identifying the person. Other biometric identification besides fingerprint can be used such as iris recognition.

Abstract: An earpiece and a method of for improving mental well-being in a person, using flashing light suppled into the ear or ears of a person. The earpiece can be worn on one ear instead of two for inducing a binaural beats effect.

Abstract: A method of monitoring an analyte in blood, particularly glycated-haemoglobin (HbA1c or HgbA1c) using two photoplethysmocharty (PPG) sensors, which are worn on the body of a subject. Each photoplethysmocharty sensor observes blood of the subject in a different wavelength. One of the wavelengths monitors glycated-haemoglobin. The other one of the wavelengths monitors the body of blood in general. The shapes of the pulses obtained by each of the PPG sensor from the subject are used to adjust the intensity of the light emitted by the PPG sensors into the subject. If on adjustment of the light intensity, the shapes of the pulses become similar, the size of the pulses can be used to provide quasi-quantification of the analyte.

Abstract: A device for monitoring heart rate or blood oxygen level during exercise is disclosed having sensors (106) and emitters (104), wherein the sensors (106) are used to monitor transmission from each of the emitters (104) 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.
