An example apparatus can comprise an emitter to emit radio frequency radiation, an absorber that changes temperature based on emissions from the emitter, and one or more sensors to measure a temperature difference between a sample and a reference coupled to the absorber.

High command fidelity electromagnetically driven calorimeter

Valve implant systems positionable within a flow passage, the systems having an inlet, an outlet, and a remotely activatable valve between the inlet and outlet, with the valves being operable to provide intermittent occlusion of the flow path. A remote field is applied to provide thermal or magnetic activation of the valves.

A method of making a single crystal comprises heating a material comprising magnetic anisotropy to a temperature T sufficient to form a melt of the material. A magnetic field of at least about 1 Tesla is applied to the melt at the temperature T, where a magnetic free energy difference &#x394;Gbetween different crystallographic axes is greater than a thermal energy kT. While applying the magnetic field, the melt is cooled at a rate of about 30&#xb0; C./min or higher, and the melt solidifies to form a single crystal of the material.

A method of controlling stoichiometry in a multicomponent material includes providing a solid sample comprising N elements and having a first composition in a main chamber, which is connected to at most N&#x2212;1 reservoirs. Each of the reservoirs is configured to contain a vapor comprising one of the N elements, where N&#x2267;2. The solid sample is heated to a first temperature in the main chamber, and each of the reservoirs is heated to a first reservoir temperature (T, T. . . T) sufficient to achieve a predetermined vapor pressure of the vapor contained therein. The reservoirs are placed in gaseous communication with the main chamber, and thermodynamic equilibrium is achieved between the vapor from each of the reservoirs and the solid sample in the main chamber. Consequently, a stoichiometry of the solid sample is changed to arrive at a second composition thereof.

A device for providing in vivo diagnostics of loads, wear, and infection in orthopedic implants having at least one load sensor associated with the implant, at least one temperature sensor associated with the implant, at least one vibration sensor associated with the implant, and at least one signal processing device operatively coupled with the sensors. The signal processing device is operable to receive the output signal from the sensors and transmit a signal corresponding with the output signal.
