  • Patent number: 6294349
    Abstract: A panel of biomarkers for the diagnosis and treatment of breast cancer was examined in the saliva of a cohort of 1) healthy women, 2) women with benign lesions of the breast and 3) women with diagnosed breast cancer. Recognized tumor markers c-erbB-2 (erb), cancer antigen 15-3 (CA 15-3), and tumor suppresser oncogene protein 53 (p53) were found in the saliva of all three groups of women. The levels of erb and CA 15-3 in the cancer patients evaluated, however, were significantly higher than the salivary levels of healthy controls and benign tumor patients. Conversely, pantropic p53 levels were higher in controls as compared to those women with breast cancer and those with benign tumors.

  • Patent number: 6293231
    Abstract: An internal combustion free-piston pump-engine provides pressurized fluid for a hydrostatic powertrain. The free-piston is reciprocably mounted in a piston bore and transfer combustion pressure directly into pressurized hydraulic fluid. Fast, computer controlled hydraulic two-way valves initiate the stepwise pressurization of the smaller face, the larger face, or both faces of the hydraulic end of the free-piston, controlling the piston movement and especially its top-end and bottom end positions. The control concept can be applied to a two-stroke, or four-stroke compression or spark ignition engine. A pressure wave charger, transfers the energy of the exhaust pressure wave into an air intake pressure wave. A cylindrical piston is reciprocally mounted in a piston bore of a housing. The exhaust pressure wave moves the piston from the top-end position to the bottom-end position, against the pressure of the intake air and the force of a return spring.

  • Patent number: 6231077
    Abstract: A dynamic control valve system adapted for inflatable restraint systems for vehicles includes a control valve having an inlet in fluid communication with a source of pressurized fluid, and an outlet in fluid communication with an inlet of the air bag. The control valve includes a valve member actuatable between a flow preventing position and a position spaced away from the flow preventing position. The control valve supplies the high pressure fluid through the control valve to the inflatable restraint for inflating the inflatable restraint when the valve member is moved away from its flow preventing position. The control valve includes a valve spool which cooperates with a valve casing to define a plurality of flow paths. Consequently, the actuation of the valve member between closed and open positions is substantially independent of forces produced by flow of the high pressure fluid through the valve.

  • Patent number: 6199823
    Abstract: A solenoid actuated valve includes a valve body and a sleeve armature slidably mounted on the valve body for movement between a flow preventing position and positions away from the flow preventing position. In one embodiment, the sleeve armature and the valve body are configured and arranged to define flow diverters in fluid flow paths to provide flow balance. The movement of the sleeve armature between closed and open positions is controlled by first and second solenoid coils, and, the sleeve armature is maintained in the position to which it has been driven by residual magnetism. In another embodiment, a solenoid actuated valve includes a bias structure for urging the sleeve armature toward the closed position. The solenoid actuated fluid flow control valve is described with reference to an application for inflating inflatable restraints for an occupant of a vehicle.
