Title: A linear position sensor utilizing time domain reflectometry and magnetic repulsion
Inventor: MCGILLIS GREG
IPC: G01B7/00
Filed: 2003-12-23
Abstract: A linear position sensor includes a linear guide having a first end and a second end. The linear guide is made of a conductive material. A follower is provided having a central aperture. The follower is positioned with the linear guide passing through the central aperture. The follower has opposed magnetic poles. A TDR instrument is positioned at one end of the linear guide. The TDR instrument is adapted to send a TDR signal parallel to the linear guide, which is directed at the follower. The TDR instrument receives a return signal reflected from the follower, which indicates the linear positioning of the follower. At least one magnet is provided which is adapted for mounting on an object. The follower is magnetically repelled to the magnet to such an extent that the follower follows the movement of the magnet.      The linear positioning of the follower provides an accurate indication of the linear positioning of the magnet mounted to the object.

Abstract: The present invention provides adipose-derived stem cells (ADSCs}, adipose-derived stem cell-enriched fractions (ADSC-EF} and adipose-derivedlattices, alone and combined with the ADSCs of the invention. In one aspect, the present invention provides an ADSC substantially free of adipocytes and red blood cells and clonal populations of connective tissue stem cells. The ADSCs can be employed, alone or within biologically-compatible compositions, to generate differentiated tissues and structures, both in vivo and in vitro.  Additionally, the ADSCs can be expanded and cultured to produce molecules such as hormones, and to provide conditioned culture media for supporting the gro.sim. and expansion of other cell populations. In another aspect, the present invention provides a adipose-derived lattice substantially devoid of cells, which includes extracellular matrix material from adipose tissue. The lattice can be used as a substrate to facilitate the growth and differentiation of cells, whether in vivo or in vitro, into anlagen or even mature tissues or structures.

Title: Attachment for preventing reverse rotation of a shaft
Inventor: ZELINSKI ELGIN RICHARD
IPC: F16D65/14
Filed: 2004-06-17
Abstract: A fan rotor is mounted on a shaft carried on bearings attached to a base plate and there is provided an assembly for preventing reverse rotation of the fan which could damage the motor. A stop plate is mounted on the base adjacent the shaft with an edge adjacent the shaft, A pair of wing members are carried on the shaft on two collar pieces so that each wing member is pivotal between ends of the collar pieces about an axis parallel to the tangent to the shaft at the wing member. The wing members are V-shaped and pivot so that one leg moves under gravity either in the vertical or horizontal orientations of the shaft from a retracted position, in which it is free from the stop plate to an extended position in which it engages the abutment surface of the stop member to prevent reverse rotation. The wing members are shaped and weighted such that rotation of the shaft beyond a predetermined angular velocity causes centrifugal force to move the wing members to the retracted position.

Title: Positioning system for moving a selected station of a holding plate to a predetermined location for interaction with a probe
Inventor: LAFFERTY WILLIAM MICHAEL
IPC: C12Q1/68
Filed: 2003-03-11
Abstract: A device for positioning the tip of an elongated probe (14) at a selected station of a holding plate (12) includes motors to move the holding plate and a supporting stage within a coordinate plane (mxy). The elongated probe is also movable along a linear probe axis that is orientated normal to the coordinate plane (mxy). A camera creates a pixel image of an optical marker placed on the stage. The image defines a coordinate plane (pxy). To relate the coordinate plane (pxy) to the coordinate plane (mxy), the optical marker is moved to successive locations in the mxy plane and a pixel image is obtained at each location. Using the pixel images, a computer calculates the relationship between coordinate planes and uses the relationship to signal the motors to move the holding plate in the mxy plane and position the selected station on the probe axis for interaction with the probe.

Abstract: Biomedical materials are encapsulated in ionically crosslinked polymer capsules, preferably alginate microcapsules. The alginate capsules are then subjected, in a liquid vehicle, to an ethylenically unsaturated monomer and an initiator, to induce polymerization of the unsaturated monomer and thereby enhance the strength of the capsule wall. The microcapsules can be after- treated with, for example, polylysine and alginate to reduce their tendency to elicit an immune response if implanted in an animal. The invention extends t o the microcapsules and also to a method of treating or preventing medical conditions in an animal particularly a human, by implanting microcapsules containing biomedical material in the animal.
