摘要： The magnetic force between the electromagnet and plunger of a magnetic actuator, the electromagnet including a coil generating magnetic flux when the coil is energized, can be increased by locating a near field plate on the electromagnet. The near field plate has a spatially modulated surface reactance configured to focus the magnetic flux within a region of the plunger, such as the central portion of an end portion of the plunger proximate the electromagnet, so as to increase the magnetic force between the electromagnet and plunger. Examples also include permanent magnet based actuators and the use of other magnetic field focusing devices.

摘要： A process for manufacturing a thermoelectric material having a plurality of grains and grain boundaries. The process includes determining a material composition to be investigated for the thermoelectric material and then determining a range of values of grain size and/or grain boundary barrier height obtainable for the material composition using current state of the art manufacturing techniques. Thereafter, a range of figure of merit values for the material composition is determined as a function of the range of values of grain size and/or grain boundary barrier height. And finally, a thermoelectric material having the determined material composition and an average grain size and grain boundary barrier height corresponding to the maximum range of figure of merit values is manufactured.
