A terrestrial communications system which comprises one or more terrestrial transmitting nodes for transmitting a first set of signals, one or more terrestrial receiving nodes for receiving a second set of signals, and a plurality of user units, each of the user units including a transceiver for transmitting the second set of signals to the terrestrial receiving nodes and for concurrently receiving the first set of signals from the respective terrestrial transmitting node, wherein the first set of signals are in a first frequency band between 11.0 GHz-13.0 GHz and wherein said second set of signals are in a second frequency band between 0.7 GHz-3.0 GHz.

A method and apparatus for detection of blood coagulation using infrared electromagnetic transmission changes through a sample from a source of infrared energy to suitable detection electronics producing a peak signal representative of the clotting time.

Measurement of blood coagulation time using infrared electromagnetic

A device for forming an orthopedic cast is disclosed which is composed of a core having a fibrous, porous tape rolled thereabout. The tape is impregnated with a first liquid component of a two-component hardenable system. The core is composed of a pressure rupturable container having the second component of the two-component system therein in liquid form. The entirety is encased in a flexible package which serves as a mixing chamber for intermixing the first and second components upon application of pressure to the package sufficient to rupture the core. After intermixing, the package is opened, the tape unrolled and placed about the broken limb in the conventional manner. The cast hardens within a short time at ambient temperature to provide a light-weight, breathable and waterproof orthopedic cast.

Spool of tape and all necessary resin-forming reactant liquids are packaged in a 'one-shot', disposable container for delivery to a physician who mounts the unopened package on an activator machine which spins it in successive operational stages to first activate the reactant liquids by mixing in a mixing region of the package and then wet the tape with the activated liquid by centrifuge, subsequent centrifuging removing excess liquid, whereupon the package is opened and the spool of tape, now damp with the curing resin thereon, is removed for winding on the patient's body to form a polyurethane resin orthopedic cast which hardens within minutes in air and without additional curing procedures. Preferred reactant liquids, plasticizers, and catalysts are disclosed, which have long shelf-life within the package. Package of materials includes special container having inner container containing one reactant liquid; means for opening inner container upon mounting package on activator machine to permit its contents to mix with other reactant liquid disposed at the bottom of the outer container; paddle members for mixing the reactants responsive to intermittent spinning of the package while in a tilted position; and an interior partition configured both to provide a funnel for channeling the polymerizing liquid into a hollow core of the tape spool, and to provide a peripherally extending excess liquid collection region surrounding and extending below the tape spool.
