摘要： This invention relates to the ultrasound enhancement of sedimentation of particulates in a particulate-bearing fluid medium while the fluid medium is undergoing centrifugation. The ultrasound energy forms standing waves in the fluid and cause particulates in the fluid, whether solids, liquids, or gases, to agglomerate in bands. The bands approximate either the nodes or antinodes of the standing wave, depending on the density of the particulate relative to the fluid. The banded or agglomerated particulate enhances the rate of sedimentation as well as the reverse flow of suspernatent by removing particulate which would otherwise impede this flow.

摘要： A hand-held centrifuge apparatus for sedimenting a fluid suspension in a sample tube, the sample tube being subjected to centrifugation at an acute angle to the axis of rotation. An electronic circuit activates an electric motor for a preselected time period as a function of voltage supplied by a battery to the motor to provide a predetermined degree of centrifugation to the sample. A voltage tester periodically tests the voltage in the circuit to assure that adequate voltage is being supplied by the battery. A deactivation circuit is actuated if inadequate voltage is sensed and a disabling circuit disables the electronic circuit until adequate voltage is again available. The disabling circuit is masked during acceleration to preclude deactivating the circuit when the motor is in acceleration.

摘要： Methods and apparatus for controlling the movement of materials having different physical properties when one of the materials is a fluid. The invention does not rely on flocculation, sedimentation, centrifugation, the buoyancy of the materials, or any other gravity dependent characteristic, in order to achieve its desired results. The methods of the present invention provide that a first acoustic wave is propagated through a vessel containing the materials. A second acoustic wave, at a frequency different than the first acoustic wave, is also propagated through the vessel so that the two acoustic waves are superimposed upon each other. The superimposition of the two waves creates a beat frequency wave. The beat frequency wave comprises pressure gradients dividing regions of maximum and minimum pressure. The pressure gradients and the regions of maximum and minimum pressure move through space and time at a group velocity. The moving pressure gradients and regions of maximum and minimum pressure act upon the materials so as to move one of the materials towards a predetermined location in the vessel. The present invention provides that the materials may be controllably moved toward a location, aggregated at a particular location, or physically separated from each other.

摘要： An automatic hematocrit reader wherein a sample of blood in a microhematocrit capillary tube is banded with a standing wave from an ultrasonic transducer. A light source and photocell combination is used to determine the relative thicknesses of the bands of red blood cells and the bands of plasma. The hematocrit of the sample of blood is electronically calculated from this data. A calibration strip is included so that the device is calibrated each time the hematocrit is determined. The device includes a mechanical interlock/eject system for the microhematocrit capillary tube and is specifically configured so that the operator does not handle or even touch the microhematocrit capillary tube.

摘要： This invention is a dual axis, continuous flow centrifuge apparatus and method. A centrifuge head rotates in a vertical orientation about a first axis which, in turn, is rotated in a horizontal plane about a second axis. The rotation of the centrifuge head is matched to the rotation of the second axis to cancel out any net rotation of flexible conduits attached to the centrifuge head. The nonrotating coupling of the conduits permits continuous flow through the centrifuge head in the absence of seals. An angled centrifuge chamber inside the centrifuge head provides a more rapid separation of the components in the liquid passing through the centrifuge head. The path of travel of a particle in a centrifuge chamber inside the centrifuge head follows a generally cycloidal path thereby undergoing a pulsatile centrifugal force component.

摘要： This invention is an ultrasound apparatus for determining hematocrit. A sample of blood in a microhematocrit capillary tube is acoustically coupled to an ultrasound transducer which creates a standing wave in the blood sample. Red blood cells in the blood sample are packed in bands that correspond to the nodes of the standing wave. The thickness of the bands as a function of the thickness of the remaining plasma is an indication of the hematocrit of the blood sample.

摘要： Methods and apparatus for maintaining urinary continence in normally incontinent individuals. The present invention involves the non-surgical implantation of a bolus of ferromagnetic material into the bladder. The bolus of ferromagnetic material may comprise a biocompatible membrane, containing a ferromagnetic material. The bolus will normally rest at the juncture between the bladder and the urethra and will prevent the flow of urine from the bladder into the urethra. Essentially, the bolus serves as a seal between the urethra and the bladder. When it is desired to void the bladder, the ferromagnetic bolus is moved out of the intersection between the bladder and the urethra by positioning a magnet along the external surface of the person's body and manipulating the magnet until the desired movement of the bolus is accomplished. Movement of the magnet is sufficient to displace the bolus such that flow may be initiated from the bladder into the urethra.
