Fabrication of doped and undoped stoichiometric polycrystalline AlN ceramics with high purity is accomplished by, for example, reacting Al pellets with nitrogen gas. Such polycrystalline AlN ceramics may be utilized in the fabrication of high purity AlN single crystals, which may be annealed to enhance a conductivity thereof.

摘要:
Reducing the microvoid (MV) density in AlN ameliorates numerous problems related to cracking during crystal growth, etch pit generation during the polishing, reduction of the optical transparency in an AlN wafer, and, possibly, growth pit formation during epitaxial growth of AlN and/or AlGaN. This facilitates practical crystal production strategies and the formation of large, bulk AlN crystals with low defect densities—e.g., a dislocation density below 104 cm−2 and an inclusion density below 104 cm−3 and/or a MV density below 104 cm−3.

摘要:
An improved system and method is disclosed for dynamically estimating the output variances of carrier-smoothing filters used, for example, in GPS receivers. By accurately estimating the output variances of the carrier-smoothing filters as they transition from initialization to steady-state operation, it is possible to calculate any required protection levels without having to wait for the filters to fully stabilize. As one example, a system for estimating output variances of a carrier-smoothing filter for use in a satellite navigation system receiver is disclosed, which includes a plurality of smoothing filters associated with a navigation processing unit in a satellite navigation receiver. One or more processors associated with the navigation processing unit executes an algorithm for each smoothing filter, which provides a method for dynamically calculating an output variance for a respective smoothing filter as it transitions in response to new input variance values. The method also predicts the settling point of the output variance for that smoothing filter given a set of pseudorange and carrier-phase values to be applied. Therefore, using this novel output variance prediction method, precision navigation applications such as, for example, airborne GPS-based precision landing system applications can begin operations with suitable calculated protection level values without having to wait for the smoothing filters to stabilize. Thus, such precision landing systems are available for use as soon as the required protection level values are reached.
摘要:
The human form punching bag comprises a punching bag and a noise maker. The punching bag may be suspended from above and used for exercise or self-defense training. The human form punching bag may have a torso portion, a right leg portion, and a left leg portion in a humanoid form and may be adapted to be punched or kicked by a user. The intersection of the torso portion, the right leg portion, and the left leg portion may define a groin area. The noise maker may be retained under a flap in the groin area of the punching bag such that a kick administered to the groin area may produce audible feedback.
