  • Patent number: 11967948
    Abstract: A method and apparatus for use in improving the linearity characteristics of MOSFET devices using an accumulated charge sink (ACS) are disclosed. The method and apparatus are adapted to remove, reduce, or otherwise control accumulated charge in SOI MOSFETs, thereby yielding improvements in FET performance characteristics. In one exemplary embodiment, a circuit having at least one SOI MOSFET is configured to operate in an accumulated charge regime. An accumulated charge sink, operatively coupled to the body of the SOI MOSFET, eliminates, removes or otherwise controls accumulated charge when the FET is operated in the accumulated charge regime, thereby reducing the nonlinearity of the parasitic off-state source-to-drain capacitance of the SOI MOSFET. In RF switch circuits implemented with the improved SOI MOSFET devices, harmonic and intermodulation distortion is reduced by removing or otherwise controlling the accumulated charge when the SOI MOSFET operates in an accumulated charge regime.

  • Patent number: 5148614
    Abstract: A closure apparatus secured to opposing sides relative to a shoe opening overlying the tongue includes a respective right and left plate member to include a belt anchor and belt buckle respectively mounting a flexible belt web therebetween, wherein the belt web is mounted pivotally to the belt anchor and received through the belt buckle to secure the belt web in an adjustable manner through the buckle. The belt anchor and belt buckle are mounted to conventional shoe lace apertures directed through respective right and left flaps relative to the shoe opening to pivotally secure the buckle and anchor thereto.

  • Patent number: 5084031
    Abstract: A three-way double stopcock and associated tubing is disclosed with which to connect both a cardioplegia solution source and a pressure monitor for the solution selectively and alternatively to either an antegrade cardioplegia catheter or a retrograde cardioplegia catheter. The stopcock includes a hollow valve body with three solution infusion ports communicating to the interior thereof in a coplanar arrangement at a first longitudinal point on the valve body. Three cardioplegia pressure monitoring ports also communicate through the valve body to the interior thereof at a second longitudinal position distinct from the first. Mounted in the valve body is a cylindrical valve core selectively rotatable about the longitudinal axis thereof between a first position in which the cardioplegia solution source and the pressure monitor are coupled to the antegrade cannula and a second position in which the cardioplegia solution source and the pressure monitor are coupled to the retrograde catheter.

  • Patent number: 4639252
    Abstract: A venous return catheter is provided having a first diameter distal portion suitable for insertion in a vena cava, a second, larger diameter proximal portion, and a transition portion forming a smooth transition between the first and second diameter portions. Drainage openings are provided in both the proximal and distal catheter portions. The catheter is of unitary construction, having a smooth bore through its entire length. It is also constructed from a soft, resilient material, but is reinforced with a harder, stiffer material in the region of the proximal drainage openings. The catheter may also be provided with wire reinforcement. The catheter is manufactured by a dip-molding process utilizing a male mandrel as a form.
