Abstract: A portable system for dynamometry, exercise, and rehabilitation comprises a base, a detachable servomotor assembly, an embedded control system, and a physical human-machine interface for securing a human limb into a stabilized position for use in a repeatable and ambidextrous manner. In another embodiment, the portable system includes a power source and a user interface subsystem for selecting operative modes and input parameters and for real-time processing, display, and storage of the values collected by the system during operation. In another embodiment, a method for determining strength of an isolated muscle group of a human joint is disclosed. The method includes the steps of mounting and securing a detachable servomotor assembly of a portable dynamometer upon a surface and securing the human joint to be tested into a stable position with an adjustable, ambidextrous distal limb attachment assembly for use of the portable dynamometer in a readily repeatable manner.

Abstract: A gas burner head with extra simmer capabilities, a burner base assembly and combinations thereof are disclosed. A gas burner head having one or a multiple fuel/air mixture exit ports with a simmer flange located above the ports and extending beyond the port exit by a predetermined distance allows the flame/fuel-air mixture from a given port to be fully or partially covered from above at a desired flame height or fuel-air mixture setting. The burner head can be a single or multiple piece assembly and can be used as part of a complete system or as an added-on component to an existing burner system. A burner base assembly has a burner base plate, a venturi and an orifice enclosure that creates a means to supply the required gas for combustion and also enables the burner head to be fully sealed. The venturi can be built-in as part of the burner base plate or made as a separate component and assembled through the burner base plate to create a sealed path.

Abstract: A video toroid cavity imager for in situ measurement of electrochemical properties of an electrolytic material sample includes a cylindrical toroid cavity resonator containing the sample and employs NMR and video imaging for providing high-resolution spectral and visual information of molecular characteristics of the sample on a real-time basis. A large magnetic field is applied to the sample under controlled temperature and pressure conditions to simultaneously provide NMR spectroscopy and video imaging capabilities for investigating electrochemical transformations of materials or the evolution of long-range molecular aggregation during cooling of hydrocarbon melts.
