The present invention relates to a wearable device for acquiring physiological information of a subject. To combine the advantages of a contact sensor and a contactless sensor, the wearable device comprises an optical emitter () for emitting light into the subject's skin, an optical sensor () for receiving light scattered back from the subject's skin in response to the emission of light into the subject's skin, the received light representing or allowing the derivation of physiological information of the subject, and a carrier () for being held at the subject's skin and for carrying said emitter () and said sensor () such that a light receiving area (), at which the emitted light enters the subject's skin, substantially corresponds to a light reflecting area (), at which at least part of the scattered light leaves the subject's skin and is received by said optical sensor, the optical sensor () is arranged between the optical emitter () and the light receiving area () and is at least partially transparent for the light emitted by the optical emitter or the optical emitter () is arranged between the optical sensor () and the light reflecting area () and is at least partially transparent for the light reflected from the light reflecting area.

Wearable device and system for acquiring physiological information of a subject

The invention relates to an assembly comprising a main device and an accessory, which can be connected by a safe connector and a safe detection method. According to the invention, the assembly comprises: &#x2014;a main device (), &#x2014;an accessory () connectable to the main device (), &#x2014;the accessory () comprising an accessory connector () for mating with a device connector () of the main device (), &#x2014;the accessory connector () and the device connector () each comprising one or more supply contacts () for transmitting electric power from the main device () to the accessory (), &#x2014;the main device () comprising a detection device (), which, if connecting the accessory () to the main device (), receives complex accessory data stored by the accessory () and which by positive evaluation of the complex data enables applying a supply voltage at the one or more supply contacts () of the device connector ().

Accessory device and assembly including same for providing secure detection of the accessory device using data transfer

Systems and methods for automatically performing one or more physiological measurements. In various embodiments, image and audio data of a setting in which a patient is present may be acquired via one or more recording devices (). A determination may be made based on the acquired image and audio data of a state of activity associated with the patient. Based on the determined state of activity associated with the patient, a corresponding one or more physiological measurements of the patient to be obtained may be identified. One or more health sensors () may then be caused to be operated to obtain the corresponding one or more physiological measurements.

Using visual context to timely trigger measuring physiological parameters

For saving power in a monitoring system for monitoring physiological data of a patient, motion activity data of the patient is obtained and measurements of physiological data of the patient are initiated, only when the motion activity is both non-zero and below a selected threshold.

Method for operating a monitoring system

The present invention relates to a signal measurement system () for measuring a signal, the system comprising a signal detection unit () for detecting a raw signal, a signal processing unit () and a signal cable () electrically connecting the signal detection unit () with the signal processing unit (). The signal cable () comprises a signal conductor () for electrically conducting a first signal from the signal detection unit () to the signal processing unit (), which first signal comprises at least the raw signal, a reference conductor () for detecting and electrically conducting to the signal processing unit () only a noise signal induced by a movement of the signal cable () or by electromagnetic interference. In this way the effect of noise on the signal quality is reduced caused by movement of the signal cable () or other sources of noise that induce a noise signal in the signal cable (), such as electromagnetic interference, while at the same time not increasing the power usage or power loss.
