Abstract: The present invention relates to a novel optical approach based on spatial analysis of spatial laser speckle patterns for tissue in-depth flow inspection characteristics. In particular, the invention relates to a technique for determining flow characteristics and identifying low blood flow or a blockage in blood vessels.

Abstract: A system for use in monitoring application is described. The system comprises a light detection unit and an illumination arrangement. The detection unit is configured for collecting light returning from a selected inspection region for determining variations in collected light intensity. The illumination arrangement comprises one or more light sources configured for providing illumination of a selected wavelength range directed toward said inspection region. Wherein the illumination arrangement is arranged around the detection unit to provide symmetrical illumination conditions with respect to an axis connecting said detection unit and said inspection region.

Abstract: A monitoring system is presented, configured for use in monitoring heart condition of a subject. The system comprises: a receiver utility for receiving input data comprising data corresponding to signals continuously collected from the subject over time N and being indicative of a sequence of heart sounds; and a processing utility configured and operable for processing said input data to determine data indicative of heart condition of the subject. The processing comprises: identifying within said input data a sequence of acoustic signals corresponding to heart sounds comprising S1 signals corresponding to ventricular contraction and S2 signals corresponding to end of ventricular systole; analyzing the sequence of acoustic signals in accordance with parameters including signal periodicity, amplitude of S1 and S2 sounds, and intervals between S1 and S2 sounds within the collected sequence; and generating data indicative of cardiac condition of the subject in accordance with the analyzed data.

Abstract: A system and technique are presented, for use in remote sensing of acoustic and/or mechanical vibration data from an inspection region.

Abstract: Embodiments of the invention relates to decreasing effects of local and/or regional anesthesia by administering to a patient in need thereof an agent selected from the group of agents consisting of reactive nitrogen species (RNS), reactive oxygen species (ROS) and/or an agent which induces formation of RNS and/or ROS. Exemplary agents which may be used include peroxynitrite and hydrogen peroxide.
