    摘要: Respiration of a patient is detected by emitting an electromagnetic signal towards the patient; receiving a reflected electromagnetic signal reflected from the patient; converting the reflected electromagnetic signal, yielding a first signal; phase-shifting the reflected electromagnetic signal and converting the phase-shifted reflected electromagnetic signal, yielding a second signal; determining a first vector being defined by the time derivatives of the first signal and the second signal, for a common first point in time; determining a second vector being defined by the time derivatives of the first signal and the second signal, for a common second point in time; and calculating the scalar product of the normalized first vector and the normalized second vector as an indicator value for a change from expiration to inspiration of the patient or vice versa. A change from expiration to inspiration of the patient or vice versa is preferably indicated if the indicator value is below a threshold value, preferably below a value of 0. In this way, respiration is monitored contactlessly and remotely based on the Doppler radar principle which is reliable and easy to handle.

    摘要: The invention relates to a waveguide (24) for focusing electromagnetic energy on an area of interest, said waveguide (24) comprising outer walls forming a channel with a width (w) and a height (h) for the propagation of the electromagnetic waves. In order to be able to focus the EM waves on an area of interest, i.e. the chest of a patient (20), so that influences which other moving objects in the environment have on the waves, are shielded away, the channel is provided with a first opening and a second opening wherein said walls are non-metal hollow walls filled with an electrically conductive liquid. The waveguide (24) can be used for example with a computed tomography system (12) CT with a rotating gantry (16) and a patient table (18). The waveguide (24) will not produce artefacts in the CT image by scattering the X-ray, like a metal wall would do it. Nevertheless the conductive liquid makes the construction work as a waveguide for EM waves.

    摘要: The invention related to a modulator for a communications system. The modulator comprises a spread spectrum coder, a pulse code modulator having a signal input port connectable to a signal output port of the spread spectrum coder. The modulator performs a robust and error free modulation and coding scheme by using a modified spread spectrum scheme combined with pulse code modulation. The communication system contains a low data rate, noise robust modulation and coding scheme using a very simple transmitter. This results in a very straightforward transmitter circuit, reducing size and costs of the transmitter.

    摘要: An apparatus measures properties of an object such as a heart in a patient (2). The apparatus includes an antenna (3, 4) for sending and/or receiving electromagnetic waves to and/or from the object (2) for measuring a property of the object. The antenna (3, 4) includes an electrically conductive element for functioning as an electrode for measuring a further property of the object. The electromagnetic waves are reflected by the object, causing a Doppler shift. The apparatus uses this shift to provide mechanical information about the object and uses the electrode to provide electrical information about the object, such as an electrocardiogram.

    摘要: The invention concerns an apparatus, system, wearable apparatus and concomitant processing system to detect instants in time at which a cyclically pulsating object within the body of an individual is temporarily quiescent, such an object being the heart, an artery or the lungs. The essence of the invention is the use of a doppler radar motion sensor, normally used for vehicular speed detection or the detection of building occupancy. The doppler radar motion sensor is arranged to transmit electromagnetic signal towards the object and receive reflected electromagnetic signal from the object, and the apparatus is further arranged to identify the instants in time at which the reflected signal indicates the object is temporarily quiescent. The invention is particularly suitable for ambulatory monitoring of the heart.
