Abstract: The invention provides a passive two-stage multiwavelength approach for measuring temperature, emissivity and stray-light levels. The first stage comprises the steps of, (1) acquiring spectral intensity measurements over a predetermined spectral width of a thermal radiation source radiating at a true effective spectral emissivity and with a true source temperature, (2) forming a composite function that relates said spectral intensity measurements to the true effective spectral emissivity and the true source temperature, (3) providing emissivity estimating means for approximately determining how the true effective emissivity affects the color temperature of the thermal radiation source, (4) substituting an estimated effective spectral emissivity for the true effective spectral emissivity within the composite function such that the estimated emissivity approximately accounts for the effects of the true effective emissivity on the color temperature, (5) substituting a source temperature projection for the true source temperature within the composite function, and (6) utilizing the composite function to provide a best-fit correlation between the spectral intensity measurements, the estimated emissivity, and the projected source temperature such that when the projected source temperature equals the true source temperature the composite function attains an extremum, thereby obtaining an approximation of said source temperature. The second stage comprises the steps of (1) utilizing spectral acquisition means to acquire and measure a set of multiple spectral intensity distributions of a thermal radiation source radiating at multiple source temperatures at an effective spectral emissivity, wherein each of the spectral intensity distributions is associated with a particular source temperature, and (2) forming a first function of at least two of the measured spectral intensity distributions and of a set of temperature variables that represent the temperatures of the spectral intensity distributions used, such that the first function attains an extremum when the temperature variables equal the corresponding source temperatures, thereby calculating the source temperatures.

Abstract: The invention, an incandescent light source, radiates a significantly larger portion of its power within the visible spectrum by enclosing an electrically heated tungsten filament, the radiant primary, within a cavity bounded by a two-layer refractory oxide composite, the radiant secondary. The scattering and absorption coefficients of both layers are manipulated such that the inner layer is substantially absorbing in both the visible and the IR, while the outer layer, though optically thick across the spectrum, is substantially absorbing (and therefore substantially emissive) in the visible while being highly reflective in the IR High temperature cavity radiation established by the radiant primary is absorbed by the inner layer of the secondary, thereby heating both layers such that they radiate brilliantly. The outward emissions of the inner layer are absorbed or reflected back by the outer layer, while the emissions of the outer layer are externally radiated at substantially higher luminous efficiency than that of a tungsten filament.

Abstract: Due largely to their high torque-to-current and torque-to-volume ratios, permanent magnet (PM) motors and generators are increasingly being used in a wide range of high performance applications, such as industrial drives, robotics, computer peripherals, and automotive applications. The present invention utilizes stator modularity to enable cost efficiency by significantly decreasing stator core manufacturing costs, and coil forming and fixturing costs in several ways. Minimizing costs extend to a novel, lightweight, support structure that does not require the usual encasement structure. The approach presents a challenge to mitigating cogging torque via popular methods; therefore a novel anti-cogging approach was developed that is a natural outgrowth of the modular layout instead of being negatively impacted by. The result is a low cost PM machine design and method with low cogging torque.
