Abstract:
The reliable and controlled allocation of network elements particularly medical sensors (2) to a network (4) without prior configuration of the wireless sensors or of the network administration system can be carried out using an allocation unit (1) for allocating network elements (2) to a wireless network (4), which allocation unit (1) comprises a transmitter which transmits, in a user-controlled manner, a code to a first network element (2), which code causes the first network element (2) to transmit its ID together with the code (encoded ID) so that the latter can be received by a second network element (3) which allocates the first network element (2) to its network (4).
Abstract:
There is provided an apparatus for use in diagnosing the presence of obstructive sleep apnea in a patient, the apparatus comprising a processor configured to receive signals representing measurements of a patient's breathing obtained during a plurality o breathing cycles by the patient while the patient is awake, convert the signals into the frequency domain and to determine a value for at least one parameter based on an analysis of the frequency-domain converted signals in one or more frequency bands covering frequencies below 100 Hz.
Abstract:
For obtaining a sequence of mutually comparable measurement results, it is desirable to position a number of electrodes on a patient body (10) at substantially the same position for each measurement. As such measurements may be performed every day, it is desirable for a patient to be able to perform the measurement at home, for example. The present invention provides a method and system (100) for enabling a not medically trained person to position the electrodes at substantially the same position for each measurement. The method comprises capturing an image (126) of the patient (10) and comparing the image (126) with a reference image (128). In the reference image (128), the electrode positions (130) are indicated. The electrode positions (130) of the reference image (128) are superimposed on the image (126) of the patient (10). An indicator system (134) indicates the position (130) of the electrodes such that the patient (10) may position the electrodes correctly.
Abstract:
The invention relates to a monitoring device (105) for remotely monitoring a heartbeat of a subject, the monitoring device comprising a remote sensor (102) for receiving a monitored signal (103) indicative of a movement of the subject's thoracic wall (101) induced by the subject's heartbeat. In an embodiment of the invention, the monitoring device (105) further comprises a triggering device (401) arranged to access the monitored signal (403) to generate a triggering signal (402) representative of a phase of the heartbeat. The invention further relates to an imaging or spectroscopy system (901), for example a magnetic resonance or computed tomography system or a cardiac 3D X-ray angiography system, arranged to acquire data from a subject, the system comprising such a monitoring device (105), wherein the system is further arranged to utilize the triggering signal (402) to synchronize the acquisition of the data to the phase of the subject's heartbeat.
Abstract:
The invention relates to an emergency response system. The emergency response system (10) comprises a central station (4) for receiving information about emergencies, whereby position information of a victim is provided and stored in a look-up table (6) of the central station (4). The central station addresses a list (7) of publicly available actuatable emergency response devices and selects a suitable device. The central station (4) transmits a trigger signal by means of a suitable communication network (3) to the selected remote actuatable emergency response device (14), which comprises communication means (13) for activating the signaling means (15) upon receipt of the trigger signal. Also, the actuatable emergency response device (14) comprises storage means (11) 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 (13), the signaling means (15) start broadcasting a message arranged to attract as many potential emergency responders to the victim as possible. The emergency response device (14) comprises navigation means (20), 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.
Abstract:
The invention relates to a method of ensuring the quality of service in a broadcast network (1) which also comprises apparatuses (Q, Z) that do not have their own quality of service functionality. An apparatus operating as a bandwidth manager (BM) monitors the data traffic in the network and, in the case of risk of the ensured quality of service, it sends control messages (A) to the source (Q) of the data stream, which messages cause this source to reduce the data stream. The control messages (A) can be particularly transmitted through the simulated transmitter of the target (Z).
