Abstract:
The magnetic shield preferably encloses circuitry connected to equipment in a high magnetic field (e.g., two transformers of a gas flow transducer in an MRI suite). The magnetic shield is preferably oriented so that its long axis is aligned with the axis of maximum magnetic sensitivity of the enclosed circuitry. The shield shunts external magnetic flux around the enclosed circuitry to protect the circuitry from saturation in the high magnetic field. The shield is preferably made from hot rolled low carbon steel which has relatively low permeability and saturates slowly. The physical size and construction of the shield reduces magnetic flux within the shield with a minimal amount of iron. In another embodiment, a magnetic field sensor is mounted within the shield to measure the magnetic field affecting the enclosed circuitry. The sensor is coupled to an external circuit which indicates when the magnetic flux is strong enough to affect the operation of the enclosed circuitry.

Abstract:
Several embodiments of a heart valve holder are described. In one instance, the heart valve holder is comprised of a plurality of hollow members having a plurality of openings formed therein. The heart valve holder is adapted to engage a heart valve through use of vacuum pressure. In another instance, a heart valve holder comprised of at least one inflatable balloon member is disclosed. When inflated, the balloon members may be used to hold the heart valve during implantation.
Handpiece System For Multiple Phacoemulsification Techniques
A handpiece system for multiple phacoemulsification procedures is provided which includes a housing having a distal end adapted for sealably and releasably engaging a plurality of nose cones and a sonic generator disposed within the housing. A horn having a body connected to the sonic generator and a needle is provided for radiating sonic energy into an eye for fragmenting eye tissue. A plurality of nose cones are provided which are adapted for being sealably and releasably engaged with the housing and provide structure enabling varied phacoemulsification procedures.
A soundboard for a hollow-body stringed instrument made of layers of carbon-fiber and resin material surrounding a core of one or more layers of constant-thickness plywood, veneer (thinly sliced wood) or paper. Additional shaped layers are provided to produce a desired pattern of stiffness in the soundboard. The soundboard may be tuned by attaching additional masses to a surface of the soundboard. A method of making and tuning the soundboard of the invention is provided.
A flexible carbon-fiber laminate material comprising a layer of carbon-fiber and resin material adhered to a layer of thermoplastic or polymer fiber material, creating a flexible carbon-fiber laminate material. A method of making the flexible carbon-fiber laminate material, by wetting the carbon fiber and cloth layers, laying the fiber layer against glass, applying a release layer and breather layer to the back of the cloth layer, encasing all the layers in an airtight bag, evacuating the bag, then removing the bag, the glass and the release and breather layers.

Abstract:
A self-adjusting mechanism ensures that the collective force on the steering cables of an endoscope or borescope is limited or relieved when a predetermined force is reached. The mechanism includes a frame, a slider that moves on the frame and restrains the proximal ends of the steering cable sheaths, and springs that bias the slider distally. The springs can be preloaded by employing a stop member to limit the distal movement of the slider.
