Title: Method and apparatus for achieving correct limb alignment in unicondylar knee arthroplasty
Inventor: HODOREK ROBERT A
IPC: A61B17/56
Filed: 2003-11-13
Abstract: A method and apparatus for correcting limb alignment in a unicondylar knee arthroplasty and linking the distal femoral cut and the proximal tibial cut.  Alignment rods are connected to a spacing apparatus to facilitate correction of limb alignment.  The alignment rods are positioned along the mechanical axis of the femur and the tibia and the knee joint is positioned to correct alignment. A spacing apparatus is positioned in the relevant knee compartment and utilized to hold the knee in position to correct limb alignment. The spacing apparatus includes a femoral cut slot through which the distal femoral cut is made and further includes tibial affixment apertures through which a headless securing device can be positioned to secure the spacing apparatus to the tibia. After the distal femoral resection is complete, the spacing apparatus is removed, with the headless securing devices remaining positioned in the tibia. The headless securing devices are used as a reference for securing a tibial cut block to the tibia for making the proximal tibial resection. With the mechanism of the present invention, the knee can be placed in flexion when making the proximal tibial cut and the distal femoral cut is linked to the proximal tibial cut.

Title: System and method for prebalancing electrical properties to diagnose disease
Inventor: GRAOVAC MILAN
IPC: A61B5/053
Filed: 2004-03-03
Abstract: A system and method for diagnosing the possibility of disease by making electrical measurements in one of a first body part and a second substantially similar body part are described. The present invention balances out differences between homologous body parts that are due to natural factors unrelated to disease, such as differences in size or symmetry between left and right breasts. Once data are prebalanced, statistical analyses can be performed on the data to diagnose disease. The system includes a normalizing module for obtaining a normalizing factors database from a screening population group to account for differences in spatial separation of impedance measurements. Once a set of normalizing factors is obtained, a prebalancing factor can be obtained that can further be used to adjust raw electrical measurements. Normalizing factors are applied to a smaller subset of measurements that are likely to better represent the body part as a whole.      This set of measurements is reduced further by eliminating a set of the measurements that can be biased by a presence of a disease in a body part.      The remaining measurements for each body part are then averaged to obtain an overall measure of a body part electrical property. The quotient between these measures is then used to adjust raw measurements. The adjusted measurements remove the imbalance that might exist due to natural differences between body parts. Adjusted measurements are then used as an input to other methods to obtain more accurate disease diagnostics.

Title: Steel rule die with closely nested cavities
Inventor: JOHNSON MICHAEL J
IPC: B26F1/44
Filed: 1996-10-18
Abstract: A steel rule cutting die for cutting fixed patterns in a single or plurality of stacked material layers according to the shape of the steel rule. The invention provides for a decrease in the quantity of scrap material produced, by minimizing the amount of gap between adjacent cavities in the steel cutting die. Pre-sharpened steel rule is used with the cutting edge shifted to the outboard side of the cavity thus reducing the amount of compensation or wedging of scrap material between adjacent cavities, and thus allowing adjacent cavities to be positioned closer to one another or to contact one another without reducing the ability to remove the scrap material after the cutting operation. Frayed scrap material can be evacuated through the base of the die by providing evacuation holes in the base substrate of the die as well as providing for evacuation of scrap material from marker notch locations along joined sections of adjacent cavities. A variety of cavity shapes can be accommodated.

IPC: H01L35/30
Filed: 2003-02-03
Abstract: A system for recovering the cooling/heating heat efficiently at the time of ventilation and is applicable even to a general house. A centralized fan (110) is coupled through a suction/exhaust pipe with a heat exchanger (120) and the heat of warmed exhaust gas from each room is recovered by means of the heat exchanger (120) before being discharged to the outside from the centralized fan (110) via the heat exchanger (120). On the other hand, the heat exchanger (120) is coupled with a tank (130) through a plumbing pipe and water pumped up from the tank (130) by means of the pump (140) is warmed through the heat exchanger (120) before being returned to the tank (130). The heat exchanger (120) cools exhaust gas from the centralized fan (110) using a Peltier element and heats up the water in the tank (130) so that the heat of air from each room transfers to water efficiently, as a whole. Since heat is transferred efficiently through a Peltier element, temperature of water from the heat exchanger can be set higher than that of the exhaust gas.

Inventor: TABER BRUCE E
IPC: C23F13/00
Filed: 2004-10-18
Abstract: The interior of a vessel containing fluid is protected against undesirable chemical corrosion and/or mechanical erosion caused by the fluid due, for example, to changes in the chemistry of the fluid, by an electrically conductive, chemically corrodable sacrificial member having an internal section disposed within the tank and an exposed exterior portion connected to an electrical corrosion/erosion detection circuit operative to create and maintain a flow of electrical current through the sacrificial member. When the internal section of the sacrificial member is subjected to a predetermined combination of fluid exposure time and fluid chemical corrosivity within the vessel a chemical corrosion gap is formed within the internal sacrificial member section. Creation of this gap terminates or at least substantially reduces electrical current flow through the sacrificial member and responsively causes the detection circuit to output a corrosion/erosion detection signal indicating the need for corrective action.
