Abstract: A magnetic switch can be configured to have or provide a variable, user-selectable radial flux pattern. In an example, the switch comprises a magnetized outer structure and a magnetized inner structure provided at least partially inside of the magnetized outer structure. In an example, at least one of the magnetized inner and outer structures is rotatable relative to the other one of the magnetized inner and outer structures about an axis of rotation that is common to the magnetized outer structure and magnetized inner structure. The radial flux pattern can extend away from the common axis of rotation and can vary in strength according to a relative position of the magnetized inner and outer structures. In other examples, the switch can comprise multiple layers of magnetized structures.

Abstract: A tension device integrated into a pillow or cushion that allows the user to manually adjust the internal arrangement and thus the thickness and firmness of the pillow by pulling on one or more cords that are attached at various locations inside or on the outside of the pillow and run through at least a portion of the interior of the pillow. The cord(s) attach to a portion of the inside or outside of the pillow, then traverse the interior of the pillow to exit a different side of the pillow than the one to which they are attached. The user then pulls on the cord(s) pulling one side of the pillow towards another and then secures the free ends of the cord(s) when the desired firmness is achieved.

Abstract: A method for photoselective vaporization of prostate tissue includes delivering laser radiation to the treatment area on the tissue, via an optical fiber for example, wherein the laser radiation has a wavelength and irradiance in the treatment area on the surface of the tissue sufficient because vaporization of a substantially greater volume of tissue than a volume of residual coagulated tissue caused by the laser radiation. The laser radiation is generated using a neodymium doped solid-state laser, including optics producing a second or higher harmonic output with greater than 60 watts average output power. The delivered laser radiation has a wavelength for example in a range of about 200 nm to about 650 nm, and has an average irradiance in the treatment area greater than about 10 kilowatts/cm2, in a spot size of at least 0.05 mm2.

Abstract: A boat cover shaped to match the bow area of a center console boat and having a flexible material with straps positioned around its periphery. The straps located on the front two edges of the cover removably attach to the rails of the boat while the straps located along the back edge of the cover removably attach to the frame of the deck of the boat.

Abstract: A method for photoselective vaporization of prostate tissue includes delivering laser radiation to the treatment area on the tissue, under direct visualization, wherein the laser radiation has a wavelength and irradiance in the treatment area on the surface of the tissue sufficient to cause vaporization of a substantially greater volume of tissue than a volume of residual coagulated tissue caused by the laser radiation. An endpoint for a procedure can be determined using the direct visualization.

Abstract: A cannulated fastener system is provided for orthopedic applications that include attaching bone plates to bone. The bone fastener has a cannulation with an inner shape. One or more screwdrivers is provided with a shaft having a shape that matches the cannulation of the fastener to rotationally fix the fastener to the screwdriver. In addition, the screwdrivers have a cutting blade that begins the drilling of a hole for the bone fastener. The screwdrivers may either be for use with a single fastener or have multiple fasteners loaded within a retaining sleeve for automatic or controlled dispensing.

Abstract: The present invention provides a compact surgical headlamp capable of dynamic adjustment of the resulting field of illumination, comprising at least a single core fiber optic delivery light guide, an adjustable light projection system, and a mounting mechanism for movably supporting the headlamp proximate to the surgeon's eyes. A receiving block is also provided for supporting the structure of the projection system and for coupling the delivery fiber thereto. The projection system comprises a cylindrical housing mount adapted with a centrally disposed cylindrical cavity for receiving the ferruled, output end of the delivery fiber and for allowing the light output therefrom to initially diverge within the cavity of the housing mount.
