Abstract: An electromechanical tourniquet includes a strap, a buckle assembly connected to the strap and utilized to secure and tighten the strap around a limb of a person and a pressure pad carried on the strap. The pressure pad provides localized application of pressure along a line extending into the limb of a person to whom the tourniquet is applied. The tourniquet further includes a force sensor to measure occlusive pressure applied to the limb along that line as well as a user interface that displays duration of use.

Abstract: An augmented synthetic resin is provided. That resin includes carbon nanotubes dispersed in a polymethylmethacrylate matrix. The method of preparing this synthetic resin includes the mixing and disaggregating of the carbon nanotubes.

Abstract: A method is provided for reducing the amount of wear particulates generated by a total joint orthopaedic implant. The implant consists of two matched articulating components wherein at least one of the components is made of polymer or other material with similar physical properties. The method includes the steps of placing the total joint orthopaedic implant in a fluid bath and articulating the implant in the fluid bath for at least 1,000 cycles. The articulation may be performed in three stages. In the first, the implant is articulated under a load of substantially 0.1-500 Newtons with sliding speeds of substantially 0.01-0.5 meters per second. During a second stage the articulation takes place under a load of substantially 100-2,500 Newtons with sliding speeds of substantially 0.01-0.5 meters per second. In the third stage the articulation takes place under a load of substantially 2,500-10,000 Newtons at sliding speeds of 0.5-2.0 meters per second.

Abstract: A method for improving consolidation of powder resin is provided. The method broadly includes the steps of: (1) sorting particles of the powder resin according to their diameter; (2) combining the sorted particles having a first diameter D1 with the sorted particles having a second diameter D2 so as to form a particle mixture; (3) applying a vibration to the particle mixture; (4) heating the particle mixture; and (5) delivering the particle mixture through a nozzle or into a mold. The particle diameters D1 and D2 are chosen so that once combined there is optimal close packing of the three-dimensional spaces between the powder resin particles.

Abstract: A non-invasive, portable electromagnetic therapeutic method and apparatus for promoting the healing of damaged or diseased living tissue including fractured bone and in particular nonunion or delayed union bone fractures are described. The method and apparatus involve generating a signal having a series of substantially symmetric voltage cycles of bursted pulses having narrow pulse widths on the order of 0.5 to 20 microseconds and converting the signal into an electromagnetic field which extends into an area for desired tissue healing. The portable noninvasive apparatus can be readily worn or carried by a patient and is capable of generating an energy-efficient symmetrical signal coacting with a coil for transducing the signal into electromagnetic pulses.
