Michael Philip Goldowsky has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Electrical test tool having easily replaceable electrical probe
    Patent number: 6504388
    Abstract: Disclosed is an improved probe housing mechanism that will allow for the quick release of a probe tip from a testing tool. The invention includes a probe housing, a double cantilevered beam for holding a probe tip, and a releasable spring mechanism for holding the beam into place. The spring mechanism can be released by squeezing the spring together or by releasing a non-removable locking screw, thereby allowing the beam to be slidably removed from the probe housing for easy replacement.
    Type: Grant

  • Hydrodynamic blood bearing
    Patent number: 6436027
    Abstract: A hydrodynamic blood bearing includes a piston disposed coaxially in a housing bore. The piston includes a cylindrical outer surface journal spaced from the bore to define a first radial gap for receiving blood as a bearing fluid for hydrodynamically supporting the piston. The piston includes two sets of bearing pads axially spaced apart from each other, with each set including circumferentially spaced apart pads for increasing tilt stiffness of the bearing defined by the journal.

  • Torsion heart valve
    Patent number: 6432135
    Abstract: A rigid leaflet blood check valve uses a torsion wire suspension to suspend the leaflet. The leaflet is non-contacting with the housing. Complete washout of all valve parts in blood contact exists. This eliminates areas of blood stasis which exist in valves employing conventional pivot bearings. Relative motion, wear, and washout problems have been eliminated in the valve.

  • Uncoupled rotary linear pump
    Patent number: 6290640
    Abstract: A fluid pump includes a piston mounted in a housing. A check valve is disposed in the piston for controlling fluid flow. A linear motor joins the piston and housing for axial oscillation of the piston to pump the fluid in unidirectional flow. A rotary motor includes magnet strips mounted in the piston and a cooperating rotary drive coil mounted in the housing. The rotary motor is magnetically uncoupled from the linear motor.

  • Contactless hermetic pump
    Patent number: 6208512
    Abstract: A hermetic pump includes a housing having a bore, an inlet, and an outlet for channeling a fluid therethrough. A shaft is disposed coaxially in the bore, and includes a journal and an impeller spaced apart therefrom. The shaft is hermetically rotated to pump the fluid through the bore from the impeller and around the journal for developing a hydrodynamic journal bearing. In one embodiment, the pump may be used in a closed loop cooling circuit.

  • Self calibrating linear position sensor
    Patent number: 6190319
    Abstract: A rotor is disposed coaxially in a tubular housing and spaced therefrom to define a gap for receiving a fluid. An ultrasonic transducer is mounted at one end of the housing in alignment with a target at a corresponding end of the rotor. Ultrasonic pulses are bounced off the target for measuring linear position thereof based on the speed of sound in the fluid and round trip pulse time between the transducer and target. The speed of sound in the fluid between the transducer and target is self-calibrated.

  • Counterbalanced pump
    Patent number: 6068588
    Abstract: Fluid is periodically pumped through a motor-driven tubular pump at a substantially constant pumping frequency. The pump includes at least one resiliently reciprocate counterbalancing ring joined to a cooperating spring having a fundamental natural frequency corresponding with the pumping frequency and pumping flowrate is varied independently of the pumping frequency.
