Abstract: A method of generating a visual representation of a complex medical diagnosis includes receiving a first signal corresponding to a measurement of a patient biological condition. A second signal corresponding to a measurement of a patient performance condition is also received. The first and second signals are processed and a visual representation of a diagnostic assessment is generated. The diagnostic assessment is based at least in part on the patient biological condition and the patient performance condition. The visual representation is marked with the measurement of the patient biological condition and the measurement of the patient performance condition.

Abstract: A system and method for balancing flows of renal replacement fluid is disclosed. The method uses pressure controls and pressure sensing devices to more precisely meter and balance the flow of fresh dialysate and spent dialysate. The balancing system may use one or two balancing devices, such as a balance tube, a tortuous path, or a balance chamber.

Abstract: An article of apparel for shielding portions of the body from flying debris such as saw splinters, drill chips, dust, grit, and other particulate matter resulting from overhead work with a hand-held tool, includes a sleeve with an arm-fitting cuff for containing one hand of a user, a porous sleeve-section connecting with the cuff, a transparent sleeve section connected above the porous sleeve section and a loop with a downward angled handle for grasping by the other hand of a user and supporting the upper end of the sleeve against an overhead; pumping action of sawing or the like is prevented by breathing action of the porous sleeve section from blowing debris out of the sleeve, and the transparent sleeve section affords good visibility combined with shielding for the user.
