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.

The invention relates to an emergency response system. The emergency response system () comprises a central station () for receiving information about emergencies, whereby position information of a victim is provided and stored in a look-up table () of the central station (). The central station addresses a list () of publicly available actuatable emergency response devices and selects a suitable device. The central station () transmits a trigger signal by means of a suitable communication network () to the selected remote actuatable emergency response device (), which comprises communication means () for activating the signaling means () upon receipt of the trigger signal. Also, the actuatable emergency response device () comprises storage means () arranged to store the position information of the emergency response device and the provided position information of the victim. Upon receipt of a suitable signal from the communication means (), the signaling means () start broadcasting a message arranged to attract as many potential emergency responders to the victim as possible. The emergency response device () comprises navigation means (), arranged to provide a routing to the victim, which is being fed-back to the responder by the user interface. The invention further relates to an emergency response device and a method for summoning an emergency responder and for routing said responder to the victim.

The invention relates to a waveguide () for focusing electromagnetic energy on an area of interest, said waveguide () 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 (), 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 () can be used for example with a computed tomography system () CT with a rotating gantry () and a patient table (). The waveguide () 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.

A device detects electrical and mechanical cardio-vascular activities of patient, especially early decompensation detection of congestive heart failure patients (CHF). The device includes a transmitter for transmitting electromagnetic signals of a predefined frequency into the chest of the patient, a Doppler radar sensor () for detecting a Doppler radar signal reflected in the patient's chest, and an ECG unit () for capturing an ECG signal of the patient's heart. This device allows for simultaneous detection of electrical and mechanical cardio-vascular activities of a patient which can be used in an easy and reliable way and which allows for implementation in a hand-held or wearable device.

This invention relates to a system and a kit for stress and relaxation management. A cardiac activity sensor () is used for measuring the heart rate variability (HRV) signal of the user and a respiration sensor () for measuring the respiratory signal of the user. The system contains a user interaction device () having an input unit () for receiving user specific data and an output unit for providing information output to the user. A processor () is used to assess the stress level of the user by determining a user related stress index. The processor is also used to monitor the user during a relaxation exercise by means of determining a relaxation index based on the measured HRV and respiratory signals, the relaxation index being continuously adapted to the incoming measured signals and based thereon the processor instructs the output unit to provide the user with biofeedback and support messages. Finally, the processor uses the user specific data as an input in generating a first set of rules defining an improvement plan for self-management of stress and relaxation. The first set of rules is adapted to trigger commands instructing the output unit to provide the user with motivation related messages. Also, at least a portion of said user specific data is further used to define a second set of rules indicating the user's personal goals.

An apparatus measures properties of an object such as a heart in a patient (). The apparatus includes an antenna () for sending and/or receiving electromagnetic waves to and/or from the object () for measuring a property of the object. The antenna () 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.

The invention relates to a system and method for measuring bioelectrical signals of a user. Furthermore the invention relates to a computer program for measuring bioelectrical signals of a user. In order to provide a technique for measuring bioelectrical signals with reduced motion artefacts a new method is provided, comprising the steps of determining the displacement of an electrode, the electrode being adapted for measuring a bioelectrical signal, and adjusting the position of said electrode depending on the determined displacement. The present invention can be used in any system for measuring bioelectrical signals, which uses electrodes, e.g. in any ECG measurement system. With the reduction of artefacts according to the present invention the performance of all those systems can be substantially increased.
