Abstract: A method of forming at least one single crystal of a Group III metal nitride. The method includes the steps of: providing a flux material and a source material comprising at least one Group III metal selected from the group consisting of aluminum, indium, and gallium, to a reaction vessel; sealing the reaction vessel; heating the reaction vessel to a predetermined temperature and applying a predetermined pressure to the vessel. The pressure is sufficient to suppress decomposition of the Group III metal nitride at the temperature. Group III metal nitrides, as well as electronic devices having a Group III metal nitride substrate formed by the method are also disclosed.

Abstract: The present invention is a method of simulating the effects of a plurality of channels on a signal that includes the steps of acquiring a state transition matrix for each of said plurality of channels; acquiring an error matrix for each of said plurality of channels; selecting the first channel to be simulated; assuming that the signal is in a particular state; receiving the signal; generating a first number; determining the state to which the signal transitions; transitioning the signal to the state determined in the last step; generating a second number; determining what errors, if any, to inject into the signal by comparing the second number to entries in the column of the error matrix of the corresponding channel that matches the state of the signal; if one of the errors determined in the last step is lost signal then discarding the signal, not injecting any other error into the signal, selecting another channel if the user desires, assuming that the next signal selected is in the same state to which the

Abstract: A router is disclosed for use in a network to carry data packets therein. Each router provides a hop along a path through the network extending from a source network address node to a destination network address node. Each route for routing data packets contains a destination network address to a next successive hop along a path between the source network address and the destination network address. Each router has a central routing processor in communication with its forwarders over a control medium to provide routing tables to each forwarder defining the next hop for forwarding received data packets for each destination address. Routing table updates of the forwarders by the central routing processor are sequentially downloaded to all forwarders simultaneously from the central routing processor, using a negative acknowledgement protocol. The central routing processor selectively responds to a negative acknowledgement message from a forwarder to re-transmit routing table updates.

Abstract: The present invention is directed to a method for changing the color of colored natural diamonds. The method includes placing a discolored natural diamond in a pressure-transmitting medium which is consolidated into a pill. Next, the pill is placed into a high pressure/high temperature (HP/HT) press at elevated pressure and elevated temperature for a time sufficient to improve the color of the diamond. The diamond may be exposed at elevated-pressure and elevated-temperature conditions within the graphite-stable region of the carbon-phase diagram—without significant graphitization of the diamond, or above the diamond-graphite equilibrium and within the diamond-stable region of the carbon-phase diagram. Finally, the diamond is recovered from said press. Colorless Type Ia and Type II diamonds may be made by this method.

Abstract: The mechanisms of the present invention provide comprehensive heuristic menu arrangement control by providing several discrete, yet complementary, features. One feature is automatic menu arrangement for both fixed and variable content menus based on a combination of frequency of selection and recency of selection. Another feature is the consideration of time of day for menu arrangement. Time of day is used in two different ways. First, time of day is used as a heuristic factor (i.e., in the same way as recency and frequency) to affect the automatic arrangement of menu items. The second time of day feature allows the user to affect the order that certain menu items are presented during a user specified time period.

Abstract: A method of enhancing the functionality and usability of a computing device includes the step of defining a plurality of functional profiles, each functional profile having a layout appearance and one or more indicators associated with applications. The functional profiles are then stored, and one of the functional profiles is activated using a functional profile selector or triggered by external communications to a personal digital assistant, e.g. SMS. Thereafter, an application is activated by selecting one of the indicators from those displayed in the layout appearance for the activated functional profile.

Abstract: A split foot damper for damping vibrational energy on a tension mask having a border with an edge. The apparatus has a first element having a first portion in moveable contact with a surface of the border and a second portion in moveable contact with the edge of the border, and a second element having a third portion in moveable contact with the surface of the border and a fourth portion in moveable contact with the edge of the border, where the two elements are connected to each other at a point that is affixed to the surface of the border. As the mask vibrates, the vibrational energy is transferred to the split foot damper, wherein vibrational energy is dissipated as the portions of the split foot damper makes contact against the surface and edge of the border.

Abstract: A jadeite material has a thickness in excess of about 1.0 mm and CIELAB indices of L*>42, a*<−6, and b*>+6. The grain size of the jadeite material is less than about 30 microns and is an equiaxed grain structure. The jadeite material has an optical transmission peak between 500 and 565 nm with an I/IO optical transmission ratio of over 40%. The first step in making the jadeite material is to wrap a glass block, convertible by HP/HT into jadeite and having a nominal composition of NaAlSi2O6, with a graphite or refractive metal sheet. The wrapped glass block is placed in an HP/HT apparatus, rapidly heated, and subjected therein to a pressure in excess of about 3 GPa and a temperature in excess of about 1000° C. for a time adequate to convert the glass block into jadeite. The jadeite material then is cooled and the pressure subsequently released.

Abstract: A technique for efficiently structuring a database takes advantage of redundancy in data point conditions to reduce the time associated with the insertion of data points into a database and to reduce the amount of required storage space. The technique is particularly suited for semiconductor characterization data having a large number of test data points collected under repeated test conditions. The data point conditions are analyzed to inventory the different unique conditions associated with the given set of data points. Each unique combination of conditions is assigned a variable array, and each variable array element identifies a specific condition. The data point values are linked to variable set handles that represent the different variable arrays. In this manner, the data points can be inserted into the database without having to store each data point value with all of the corresponding conditions. Rather, the data point values are stored along with their respective variable set handles.
