DEVICE, SYSTEM AND METHOD FOR MEASURING VITAL SIGNS
First Claim
1. A device for measuring vital signs, comprising:
- a transceiving unit capable of emitting electromagnetic signals and of directionally sensing reflected electromagnetic signals; and
a control unit capable of determining a direction of interest based on the sensed reflected signals and of adjusting a direction of sensitivity of the transceiving unit to the direction of interest.wherein the device is operable in a stand-by mode, in which the device determines in predetermined intervals, whether a person is present, and wherein the device is activated for measuring vital signs, if a person is present.

Abstract
In order to provide means for measuring vital signs such as heart rate, breathing rate, pulse forms, that allow accurate and unobtrusive signal acquisition and that are automatically adjusted to varying positions of an area of interest within a pre-determined area, a device, a system and a method for measuring vital signs are provided, wherein electromagnetic signals such as microwave or radar are emitted and reflected electromagnetic signals are sensed with directional sensitivity by a transceiving unit and wherein a direction of interest is determined based on the sensed reflected signals and a primary direction of sensitivity (300) of the transceiving unit is adjusted to the direction of interest by a control unit. Thus, vital signs can be monitored in an unobtrusive and simple way.
