  • Publication number: 20190159728
    Abstract: Splints for diagnostic and/or therapeutic purposes are disclosed. In one aspect, the present disclosure relates to a splint system for diagnostic and/or therapeutic functions for a patient with a vascular impairment. In one embodiment, the splint system includes a splint having: a leg supporting portion and a foot supporting portion, that are configured to support and secure the leg and foot of the patient; a locally and/or remotely controllable portion for setting a dorsiflexion angle of the foot of the patient, including electrical and/or mechanical controls and one or more actuators for setting of the dorsiflexion angle, for providing treatment to improve vascular function; and a plurality of physiological parameter sensors for measuring physiological parameters of the leg and/or foot of the patient, wherein the physiological parameters are associated with vascular function in the leg and/or foot of the patient.

  • Patent number: 6986873
    Abstract: A method of producing a single-phase composition Mn+1AzXn, primarily the production of the single-phase material Ti3SiC2, where n lies within a range of 0.8-3.2, where z lies within a range of 0.8-1.2, where M is at least one metal taken from the group of metals Ti (titanium), Sc (scandium), V (vanadium), Cr (chromium), Zr (zirconium), Nb (niobium) and Ta (tantalum), where X is at least one of the non-metals C (carbon) and N nitrogen), and where A is at least one of the chemical elements Si (silicon), Al (aluminum) and Sn (tin) or a compound of those elements, such that the final, desired compound will include the components Mn+1AzXn. A powder mixture of the components is formed and is ignited under an inert atmosphere to prevent promotion of dissociation and to cause the components to react.

  • Patent number: 5942455
    Abstract: Products having single phases or solid solutions of the formula M.sub.3 X.sub.1 Z.sub.2 wherein M is a transition metal, X is Si, Al or Ge and Z is B, C or N can be prepared by taking a powdered mixture containing M, X and Z to a temperature of about 1000.degree. C. to about 1800.degree. C., optionally simultaneously under a pressure of about 5 MPa to about 200 MPa. The products so formed have excellent shock resistance, oxidation resistance and machinability. The products may also be present as composites, preferably composites which are in thermal equilibrium with the single phase or solid solutions of the formula M.sub.3 X.sub.1 Z.sub.2.
