Abstract: Method and system for radiolocation of RF transmitter in the presence of multipath interference. RF receivers are spatially separated at known locations in a moderate multipath environment in the vicinity of the transmitter. Upon detection of a received active RF signal associated with the transmitter, the receivers are directed to acquire measurements of the detected RF signal. Each receiver obtains a sequence of measurements of the RF signal at different positions along a trajectory that provides multiple measurements at relative phase differences between the direct-path and the multipath reflections of the detected RF signal. The receivers may be repositioned automatically or manually, or prearranged or selectively deployed at fixed positions along the trajectory. TDOA measurements between pairs of receivers are calculated based on the obtained measurements, and are averaged to provide a respective updated TDOA measurement value for each receiver pair, which is used to determine the transmitter location.

Abstract: A wrist-mounted device for measuring at least one physiological parameter of a subject. The present invention enables such a measurement to preferably be transformed into clinically useful information about the subject. Such information may then optionally be sent to medical personnel, for example at a contact and/or monitoring center, through a gateway device. The gateway device preferably communicates with the wrist-mounted device of the present invention through a wireless communication channel.

Abstract: A wrist-mounted device (100) for measuring at least one physiological parameter of the user. The present invention enables such a measurement to preferably be transformed into clinically useful information about the user. Such information may then optionally be sent to medical personnel, for example at a contact and/or monitoring center. The measuring parameters may include blood pressure, ECG, location. The present invention can perform a Holter process over more than one physiological parameter.

Abstract: A system and method for automatically monitoring at least one physiological function of the user, without active intervention by the user, in a non-invasive manner. Such monitoring may be used to detect a deterioration in the health of the user. Preferably, the system according to the present invention features at least one physiological sensor for measuring the physiological parameter of the user to obtain the measurement of a physiological function, a local processing unit for extracting medical information from the physiological measurement, and a main server for processing the medical information in order to evaluate the health of the user. Such an evaluation is preferably performed by comparing medical information which has been obtained from a plurality of physiological measurements. Optionally and more preferably, the user is alerted if the evaluation detects a deterioration in at least one physiological function.
