Title: Universal resistance cross-training system
Inventor: CIRJAK DAVID
IPC: A63B23/04
Filed: 1996-08-16
Abstract: A universal resistance cross-training system is described which is adapted to direct a variety of resistance forces to robust portions of an exerciser's limb, while leaving hands and feet free for normal use. The system is based upon an arched cuff which provides both transverse compression sockets at either end and ratcheted channels following the outside surface of the cuff and extending between the two compression mounts. Resistance devices such as fins, elastics, weights, parachutes, floats, and linkages are connected to the cuff via either the compression sockets or the ratcheted channel.

Patent CA-2186225-A1 (CA)
Inventor: CASCIANI JAMES R
IPC: A61B5/1464
Filed: 1995-03-31
Abstract: A pulse oximeter sensor (410) with a light source optimized for low oxygen saturation ranges and for maximizing the immunity to perturbation induced artifact.  Preferably, a red (112) and an infrared light source (114) are used, with the red light source (112) having a mean wavelength between 700-790 nm. The infrared light source (114) can have a mean wavelength as in prior art devices used on patients with high saturation. The sensor of the present invention is further optimized by arranging the spacing between the light emitter (112, 114) and light detectors (116) to minimize the sensitivity to perturbation induced artifact. The present invention optimizes the chosen wavelengths to achieve a closer matching of the absorption and scattering coefficient products for the red and IR light sources. This optimization gives robust readings in the presence of perturbation artifacts including force variations, tissue variations and variations in the oxygen saturation itself.

Title: Plasma Arc Torch and Method of Operating the Same
Inventor: ENYEDY EDWARD A
IPC: B23K10/00
Filed: 1996-10-02
Abstract: A plasma arc torch comprises relatively displaceable electrode  and nozzle components  having  first  and  second positions relative to one another in which the electrode respectively contacts the nozzle and is spaced an operating distance therefrom.  Arrangements are disclosed for relatively displacing the electrode and nozzle between the first and second positions  thereof with a pre-determined  force  of engagement therebetween in the first position, and without having to interrupt the flow of arc gas and/or the flow of arc current during such relative displacement.  A torch start up safety test procedure is performed by sequentially displacing the electrode and nozzle between the two positions thereof, sensing for appropriate open and closed circuit conditions therebetween, and enabling the creation of a pilot arc only when a pre-determined  sequence of  circuit conditions  is sensed.  Sequential displacement of the electrode and nozzle together with the application of a pre-determined force of engagement therebetween promotes cleaning of oxides from the area of contact between the electrode and nozzle.

Title: Compositions for neutralization of lipopolysaccharides
Inventor: WRIGHT SAMUEL D
IPC: A61P31/04
Filed: 1995-06-07
Abstract: The present invention relates to compositions and methods for neutralizing lipopolysaccharide, and treatment of gram-negative sepsis based thereon. Accordingly, the invention is directed to a composition of homogeneous particles comprising phospholipids and a lipid exchange protein, such as phospholipid transfer protein or LPS binding protein. The lipid exchange protein is characterized by being capable of faciliting an exchange of lipopolysaccharide into the particles. In a specific embodiment, exemplified herein, the lipid particles are high density lipoprotein particles comprising apolipoprotein A-I (apo A-I), a phospholipid, and cholesterol or a lipid bilayer binding derivative thereof. In a specific example, the phospholipid is phosphatidylcholine (PC). In a specific example, the ratio of phosphatidylcholine: cholesterol: apolipoprotein A-I is approximately 80:4:1. The level of LPS exchange protein activity in a sample from a patient provides a diagnostic, monitoring, or prognostic indicator for a subject with endotoxemia, gram-negative sepsis, or septic shock.
