  • Patent number: 7976648
    Abstract: Cold worked nickel-titanium alloys that have linear pseudoelastic behavior without a phase transformation or onset of stress-induced martensite as applied to a medical device having a strut formed body deployed from a sheath. In one application, an embolic protection device that employs a linear pseudoelastic nitinol self-expanding strut assembly with a small profile delivery system for use with interventional procedures. The expandable strut assembly is covered with a filter element and both are compressed into a restraining sheath for delivery to a deployment site downstream and distal to an interventional procedure. Once at the desired site, the restraining sheath is retracted to deploy the embolic protection device, which captures flowing emboli generated during the interventional procedure. Linear pseudoelastic nitinol is used in the medical device as distinct from non-linear pseudoelastic (i.e., superelastic) nitinol.

  • Publication number: 20090221058
    Abstract: The present invention discloses a potentiometric biosensor for detecting lactate in food, and the forming method thereof. The disclosed biosensor comprises a substrate, and conducting layer on the substrate, an oxide layer on the conducting layer, and an enzyme layer on the oxide layer, wherein the enzyme layer comprises Lactate dehydrogenase (LDH). The detection signal is transmitted for further processing through a wire connected to the conducting layer, or a window formed on the surface of conducting layer.

  • Patent number: 6474211
    Abstract: A scroll saw includes a machine base and a table mounted pivotally on the machine base for placement of a workpiece to be sawn. The table is rotatable about a horizontal axis that extends in a longitudinal direction of the machine base. A C-shaped blade-holding arm is fixed on the machine base, and has upper and lower arm portions that extend in the longitudinal direction of the machine base. A saw blade is held between front ends of the upper and lower arm portions of the blade-holding arm, and extends perpendicularly through the table. A saw-blade driving device includes a motor which is disposed within the machine base, and which is provided with a motor shaft. The motor shaft extends in the longitudinal direction of the machine base. A linkage interconnects the motor shaft and the saw blade so as to reciprocate the saw blade relative to the blade-holding arm.
