Abstract: A contactless physiological measurement device is disclosed. The contactless physiological measurement device is an electronic device comprising a processor and a memory storing an application program. When the application program is executed, the processor controls a front camera and a rear camera of the electronic device to photograph a user, so as to obtain a face image and a hand image. Subsequently, after extracting a first rPPG signal and a second rPPG signal from the face image and the hand image respectively, physiological parameters are calculated by apply a signal process to the first/second rPPG signal. Moreover, a signal parameter difference is also acquired after applying a signal difference calculation to the two rPPG signals. Consequently, an estimation value of blood pressure is outputted by inputting user anthropometric parameter, said signal parameter difference and at least one physiological parameter into a pre-trained blood pressure estimating model.

Abstract: An apparatus and method for employing the macro- and micro-structure of sleep and similar states of consciousness to optimize pain-treatment are disclosed wherein an objective biomarker of pain-related sleep disturbance guides pain treatment from a sleep perspective. Furthermore, this concept can be extended to states of reduced consciousness such as coma or sedation. Additionally, it could be applied on individuals who are non-communicative due to injury, disease, language issues and/or infancy.

Abstract: An electronic apparatus of a bio-signal measurement system comprises a first electric connector arrangement that is repeatedly connectable with and releasable from a first electric counter-connector arrangement of the bio-signal data processing apparatus. The electronic apparatus comprises also a second electric connector arrangement that is connectable with a second electric counter-connector arrangement of the bio-signal electrode arrangement in a releasable manner, and a battery that provides electric power for operation of the bio-signal data processing apparatus in response to an electric connection through the first electric connector arrangement between the electronic apparatus and the bio-signal data processing apparatus. The first electric connector arrangement comprises separate electric connectors, each of the connectors with a plurality of pins, the pins of the at least two separate electric connectors being for electric power supply and data transfer. The separate electric connectors of the first electric connector arrangement and their counter-connectors of the bio-signal data processing apparatus have structural shapes matched with each other for attaching them together based on contact friction in the releasable manner.

Abstract: Stress information can be determined for a user associated with a wearable device, such as a user wearing a wearable computing device including one or more sensors. At least some of this sensor data can be combined with relevant data provided by a user to calculate a stress score, such as may correspond to a current stress level or stress resilience level of that user. Changes in this stress score can be monitored over time, and appropriate actions taken, such as to provide information or recommendations to the user, or to modify operation of the wearable computing device.
