Abstract: Apparatus is provided, including a sensor, adapted to generate a sensor signal indicative of biorhythmic activity of a user of the apparatus, the sensor signal having a first characteristic, indicative of a voluntary action of the user, and a second characteristic, indicative of a benefit-related variable of the user. The apparatus also includes a control unit, adapted to receive the sensor signal, and, responsive to the second characteristics generate an output signal which directs the user to modify a parameter of the voluntary action indicated by the first characteristic.

Abstract: Apparatus for improving health of a user is provided, including a first sensor, adapted to measure a first physiological variable, which is indicative of a voluntary action of the user. A second sensor is adapted to measure a second physiological variable, which is substantially governed by an autonomic nervous system of the user. Circuitry is adapted to receive respective first and second sensor signals from the first and second sensors, and, responsive thereto, to generate an output signal which directs the user to modify a parameter of the voluntary action.

Abstract: A system for modifying naturally occurring biorhythmic activity including a monitor for analyzing biorhythmic activity of a user, a biorhythmic activity modifier for providing to the user a stimulus input which is operative to change at least one aspect of the biorhythmic activity of the user, and a driver operative to control the operation of the biorhythmic activity modifier, so as to change at least one non-frequency characteristic of the input to the user, in response to changes in the biorhythmic activity of the user during operation of the modifier. A method for modifying naturally occurring biorhythmic activity is also described.

Abstract: A flow cell for monitoring blood or any other cell suspension under flow prises a rigid transparent base having a pair of holes with inlets and outlets. One hole transfers the cell suspension from a supply to a flow channel and the other hole transfers the tested suspension back from the flow channel to a receiver. A flow plate is sandwiched between the base and a transparent plate. The flow channel is a wide hole in the middle of the flow channel plate which can be an integral part of either the base or the transparent plate. The transparent plate covers the flow channel plate and a rigid cover covers the transparent plate with a hole enabling a microscope objective to approach the flow channel plate. The transparent plate and the cover are attached to each other firmly by any conventional method or the transparent plate can be an integral part of the cover.

Abstract: Stress detecting device for monitoring respiration, including a base supporting a transducer responsive to forces applied, at least indirectly, thereon by a slideably engageable belt, for producing electrical signals representative of magnitudes of the forces, and an element allowing at least one component of the forces in a selected direction to be applied to the transducer, while supressing application of other components in other directions of the forces to the transducer. A method for detecting and monitoring circumferential changes in the chest or abdomen of a user resulting from breathing, is also disclosed.

Abstract: A biorhythm modulator, consisting of a sensor for monitoring biorhythmic activity of the body of a user, a circuit for continuously analyzing the biorhythmic activity and producing parameter signals based upon a biorhythmic activity, a circuit for generating selectable sound-code pattern signals, a central processing unit (CPU) connected to receive signals from both the activity characteristic parameters producing circuit and the selected sound patterns generating circuit, and to feed the signals of the parameters and patterns to a sound pattern synthesizer for producing music-like sound pattern signals, transduceable into audible music-like patterns, and having a rhythm which is non-identical to the rhythm of the biorhythmic activity. A method for modulating biorhythmic activity is also described.

Abstract: An electronic device for monitoring changes in characterizing properties of a tested sample by observing displacements of a selected point on a curve of a frequency spectrum of a tested sample. The device includes a generator for generating at least one continuous wave of a predetermined constant frequency and a constant amplitude, or for generating a continuous wave of a predetermined frequency modulation about a constant frequency and amplitude, a resonator applicable to a tested sample to form a resonating system, the system being connected in circuit to the generator and driven thereby when the continuous wave is passed therethrough, and a circuit for continuously demodulating the output signal of the resonating system to form an amplitude modulated waveform representative, of the instantaneous displacements of the selected point occuring when the continuous wave is passed through the tested sample.

Abstract: The invention provides an ultrasonic device for continuously and noninvasively monitoring instantaneous fluctuations in viscoelastic-related properties of tissue comprising a pair of substantially parallel spaced-apart piezoelectric transducers having a gap therebetween and adapted to bracket and come in direct contact with living tissue inserted in the gap between the transducers, at least one of the transducers being adjustable with respect to the other transducer whereby the distance between the transducers is adjustable to enable insertion and clamping of a segment of living tissue therein. The invention also provides a method for continuously and noninvasively monitoring instantaneous fluctuations in viscoelastic-related properties of a tissue with high resolution utilizing such a device.
