An apparatus and method () for capacitive measurement of electrophysiological signals () suppresses or reduces motion artifacts by providing a feedback mechanism. An average voltage between a capacitive sensor electrode () and the body () is controlled so as to reduce or minimize motion-induced signals.

This invention relates to a method and a system for monitoring skin color of a user. The system comprises a capturing unit, an obtaining unit, a deriving unit and a determining unit. The capturing unit captures at least one image of the user over a predetermined time period, and the obtaining unit obtains motion-related information of the user over the predetermined time period. The deriving unit derives visual information from the at least one image on the basis of the motion-related information, and the determining unit determines the skin color on the basis of the derived visual information. In this way, the skin color of the user can be effectively monitored without exposing the user to strong environmental light.

A sensor device () for determining a flow characteristic of an object () being movable in an element () comprises a light emitting unit () configured for emitting light towards the element () and a light detecting unit () configured for detecting light scattered back from the element (). The sensor device () comprises an optical unit () configured for spatially separating a light incidence element portion () of the element () and a light detection element portion () of the element () from one another, wherein the light incidence element portion () is associated with the emitted light inciding on the element () and the light detection element portion () is associated with the back-scattered light scattered back from the element () for detection. The sensor device () comprises a determining unit () configured for determining the flow characteristic of the object () being movable in the element () based on light indicative of the emitted light and the detected back-scattered light. The sensor device () allows for an accurate and easy determination of the flow characteristic of the object ().

A sensor device and a method for the determination of the amount of target particles at a contact surface adjacent to a sample chamber include detecting, by a detector, the target particles in the sample chamber by a sensor element, and providing at least one corresponding sensor signal. An evaluation unit determines the amount of target particles in a first zone at the contracts surface and in a second zone a distance away from the contact surface based on this sensor signal. In an optical measurement approach, frustrated total internal reflection taking place under different operating conditions, such as wavelength and/or angle of incidence, may be used to extract information about the first and second zones. In a magnetic measurement approach, different magnetic excitation fields may be used to excite magnetic target particles differently in the first and second zone.

In an embodiment, an oxygen sensor comprises a giant magnetoresistance device (), and a magnetic field generator () arranged to generate a magnetic field () overlapping the giant magnetoresistance device and an examination region (). A component (B) of the magnetic field detected by the giant magnetoresistance device is dependent upon an oxygen concentration in the examination region. In an embodiment, a chip () includes one or more electrically conductive traces () disposed on or in the chip and a giant magnetoresistance device () disposed on or in the chip such that electrical current flowing in the trace or traces generates a magnetic field () that overlaps the magnetic field sensor, said magnetic field being perturbed (B) by ambient oxygen () such that a signal output by the magnetic field sensor indicates ambient oxygen concentration.

The invention relates to a method of monitoring a vital parameter of a patient by measuring attenuation of light emitted onto tissue of the patient, comprising the following steps: modulating the light with a modulation frequency or/and a modulation code; emitting the modulated light onto the tissue of the patient; collecting light which is transmitted through the tissue or/and which is reflected from the tissue; demodulating the collected light; analyzing the demodulated collected light with regard to interference with ambient light; determining a modulation frequency or/and a modulation code for which interference with the ambient light is minimized or falls under a predefined threshold; and setting the modulation frequency or/and the modulation code for modulating the light according to the determined modulation frequency or/and a modulation code for which interference with the ambient light is minimized or falls under a predefined threshold. In this way a versatile and reliable possibility of monitoring a vital parameter of a patient with a high signal-to-interference ratio is provided.
