  • Patent number: 7320587
    Abstract: Contact lens molds and systems and methods for producing contact lens molds are described. The contact lens mold sections include two optical quality surfaces, a flange circumscribing at least a portion of the two optical quality surfaces, and an elongate member extending from the flange. Two mold sections can contact one another to form a mold assembly having a contact lens shaped cavity. The mold sections are structured to form a contact lens having an edge that does not require further physical modification before placement on an eye. Systems and methods are described which direct a molten polymeric material into cavities corresponding to the mold sections.

  • Patent number: 6572624
    Abstract: An apparatus for positioning instrumentation into a target region of a brain generally includes an attachment member, specifically a disc adapted to be secured to a cranium, and a marker assembly adapted to be connected to a locator device, for example a conventional stereotaxic assembly. The marker assembly includes a detachable cannula, and is further adapted to be secured to the attachment member in order to immobilize the cannula at a precise position in the brain, thus facilitating additional imaging of the patient in order to determine the position of the cannula with respect to the target region.

  • Patent number: 6531146
    Abstract: Resorbable polylactide polymer scar tissue reduction barrier membranes and methods of their application are disclosed. The scar-tissue reduction barrier membranes are constructed entirely of polylactide resorbable polymers, which are engineered to be absorbed into the body relatively slowly over time in order to reduce potential negative side effects. The scar tissue reduction barrier membranes are formed to have thicknesses on the order of microns, such as, for example, thicknesses between 10 and 300 microns. The membranes are preshaped with welding flanges and stored in sterile packaging.

  • Patent number: 6453681
    Abstract: An improved and simplified system for densifying a cryogenic liquid for space vehicles is provided, which includes a heat exchanger having heat exchange tubes therein for receiving a flow of liquid from a storage tank, for example a liquid propellant in a vehicle storage tank. The heat exchanger is filled around the exchange tubes with a two-component bath, the volume of a primary component substantially exceeding the volume of a secondary component. The secondary component has a boiling temperature that is lower than the boiling temperature of the primary component, and both are lower than the boiling temperature of the cryogenic liquid. In one example, the liquid to be densified is oxygen, the primary component is liquid nitrogen, and a secondary component is liquid hydrogen. The secondary component is preferably injected into the heat exchanger in separate flows to prevent localized freezing of the first component.

  • Patent number: 6159147
    Abstract: A real-time biological data processing PC card is lightweight, cost effective, and portable. The real-time biological data processing PC card is capable of converting a host personal computer system into a powerful diagnostic instrument. Each real-time biological data processing PC card is adapted to input and process biological data from one or more biological data sensors, and is interchangeable with other real-time biological data processing PC cards. A practitioner having three different real-time biological data processing PC cards, for example, each one corresponding to a different biological data collection device, effectively carries three full-sized, powerful diagnostic instruments. The full resources of a host personal computer can be utilized and converted into a powerful diagnostic instrument, for each biological data collection device, by the insertion of one of the real-time biological data processing PC cards.
