  • Patent number: 7241305
    Abstract: A filter for filtering micro-emboli from a patient's blood during an angioplasty procedure is disclosed which comprises a plurality of curved wires connected to a rod between a first connector fixed with respect to the rod and a second connector slidingly mounted on the rod. Two layers of filter material are connected to opposite sides of the wires, and each layer includes perforations which are offset from the perforations in the other layer. When the rod and the wires are disposed within a catheter, the inner wall of the catheter compresses the wires toward the rod and when the rod is extended from the catheter, the wires resume their curved shape and pull the sliding connector along the rod toward the fixed connector.

  • Publication number: 20070119671
    Abstract: A decoupled mono tube damper assembly for a vehicle includes an outer tube attached to the vehicle's unsprung mass. The outer tube has a base and a sleeve end. An outer tube sleeve engaging end of an inner tube is slidingly engaged with the sleeve end. The inner tube has an end distal to the sleeve engaging end, and is attached to the vehicle's sprung mass at the distal end. A damper rod has one opposed end extending axially into a base aperture, and an opposed end connecting to the inner tube. The rod moves axially relative to the outer tube, due to forces transmitted from the unsprung mass. A low amplitude energy-managing member is operatively disposed within the outer tube, and has a throughbore receiving the rod. A travel-limiting member attaches to the rod and is engageable with the energy-managing member. The travel-limiting member constrains axial movement of the rod through the outer tube base to a predetermined limit.

  • Publication number: 20070075575
    Abstract: A car seat alarm has an on/off switch that is initiated by clicking the latch on the car seat. (“Pumpkin” or removable carrier infant seats may use a two-part switch.) Initiating the circuit when clicking the child into the seat would conserve battery life. The device would be off when the seat is unlocked. Additionally, if an occasion arose where a parent or caregiver were sitting in the vehicle with a child and needed to have the engine off, that parent or caregiver would simply need to unclick or unlock the child car seat restraint to deactivate the device. A learning or programmable chip can be programmed to the same frequency as the panic button on the key fob. This may be done by pressing the panic button on the key fob in close proximity to the learning circuit on the seat.

  • Patent number: 7188382
    Abstract: This device is made to protect the bony surfaces of a foot from prolonged pressure and ultimate skin breakdown. It consists of a cylinder of dense foam that is fitted to encompass the lower leg of a user from the knee to the ankle. When in place on the leg a of a user lying in bed, it will support the lower leg such that the foot will not be in contact with the firm surface of the bed, thus providing total pressure relief to the foot. The user can also lie in any position, even prone, with out interference from this device.

  • Publication number: 20060225979
    Abstract: Dampers for vehicle suspensions include a housing comprising a tube attached to a wheel axle of a vehicle and a piston rod extending from a piston within the tube and attached to the vehicle body. The piston divides the tube into first and second chambers. In order to damp responses when minor smooth road imperfections impart low force excitations to the wheel of the vehicle, a fluid bypass passageway in the form of a sleeve is positioned around the tube and overlies the piston. This provides second stage quasi-ideal damping at low force excitations to the wheels and thus to the wheel axles of the vehicle. The sleeve communicates with the first and second chambers through metered orifices or valves. As low force excitations from smooth road imperfections displace fluid within the tube through the metered orifices or valves, the orifices damp responses to the low force excitations, thereby smoothing the ride of the vehicle.

  • Publication number: 20060229791
    Abstract: The ability of a damper to attenuate smooth road shake in a vehicle is tested using a test fixture that is controlled by inputting data for periodic low amplitude periodic excitations having a selected frequency range, selected amplitude range and a selected dither representative of vehicle operation on relatively smooth roads. The selected frequency range is about 5 Hz to 30 Hz and the selected amplitude range is about 0.05 mm to 2.00 mm. A preferred frequency is about 15 Hz which is applied preferably for about 200 cycles in a series of separate tests at individual amplitudes of, for example, 0.05, 0.10, 0.15, 0.20, 0.25, 0.50, 1.00 and 2.00 mm. The damper is tested to produce low amplitude test results comprising displacement, force and velocity parameters, measured as functions of time.

  • Publication number: 20040167421
    Abstract: An electrical parameter imaging apparatus and method includes the acquisition of a charge distribution pattern on an array of electrodes that surround an object being imaged. In addition the exterior boundary, or contours of the object is measured by an array of light beams and associated light sensors. The contour measurement is employed to provide a first estimate of the object geometry needed to compute an electrical parameter image from the acquired charge distribution pattern.

  • Publication number: 20040024306
    Abstract: Methods of cardiac diagnostics of a patient are provided that include administering a stress test to the patient, acquiring a plurality of MRI cine loops of the heart of the patient at a plurality of heart rates, adjusting the plurality of MRI cine loops based on a heart rate associated with respective ones of the MRI cines so as to compensate for differences in heart rate and evaluating the compensated MRI cine loops so as to assess a state of coronary physiology of the patient. Furthermore, the administration of the stress test may be adjusted based on the evaluated compensated MRI cine loops. Also, the evaluation of the compensated MRI cine loops may determine a presence or absence of coronary artery disease based on the compensated cine loops.
