摘要： Systolic blood pressure of a subject is determined by application of monotonic changing pressure conditions over a region of an organ of the subject, simultaneous illumination of a tissue in the pressurized organ with light and measurement of optical data indicative of passage of the light through the tissue and of pressure data indicative of the pressure being applied over said region of said organ. At least one pulsatile and at least one baseline component are determined from the measured optical data and changes are then identified in each of the components, said changes indicative that the pressure applied over the organ is smaller than systolic blood pressure of the subject. The systolic blood pressure of the subject may be determined as a maximal applied pressure at which at least one of the changes in the pulsatile component and the changes in the baseline component started to appear.

摘要： Techniques for determining average value of an arterial blood pressure parameter of an examined subject are disclosed. A pressure device is used to apply changing pressure conditions over a body part of a subject and generate pressure measurement data indicative of the pressure applied. A first measuring unit measures blood-pressure-pulse related signals in the pressure-affected body part, and generate blood-pressure-pulse related measurement data indicative thereof, and a second measuring unit measures blood-pressure-pulse related signals in a pressure-free body part of the examined subject, and generate reference blood-pressure-pulse related measurement data indicative thereof. A control unit is used to operate the pressure device to apply the changing pressure conditions over the pressure-affected body part and simultaneously operate the first and second measuring units, determine an initial blood pressure parameter value of the subject based on the measurement data from the pressure device and from the first measuring unit, determine a correction factor based on the measurement data from the second measuring unit and from the first measuring unit, and determine the average blood pressure parameter of the examined subject based on the initial blood pressure parameter value and the correction factor.

摘要： It is an object of the disclosed technique to provide a novel method and system for shared concurrent access to a memory cell. In accordance with the disclosed technique, there is thus provided a system for shared concurrent access to a memory cell, which includes at least one shared memory cell, an evaluator and a plurality of processing agents coupled to the input of the evaluator. The evaluator is further coupled with the at least one memory cell. The evaluator is configured to evaluate an expression for performing multiple concurrent composite assignments on the at least one shared memory cell. The evaluator further allows each of the plurality of processing agents to perform concurrent composite assignments on the at least one shared memory cell. The composite assignments do not include a read operation of the at least one shared memory cell by the plurality of processing agents.

摘要： There is provided an apparatus for measuring the refractive index of fluids. The apparatus comprises a substantially U-shaped sensor rod made of a transparent material and is submersible in the fluid. The bent portion of the sensor rod has a diameter of curvature at least two times larger than the diameter of the sensor rod, and chosen so as to optimize sensitivity for a given range of indices. The two ends of the U-shaped sensor rod are connectable to a housing and a light source inside the housing has optical access to the face of one of the sensor-rod ends. A light detector means also disposed inside the housing has optical access to the face of the other one of the sensor rod ends.
