Abstract: A rotating cutter for a fixed cutter type bit includes an annular sleeve with a retainer having a plurality of inwardly extending tabs and a spindle cutter rotatably coupled to the annular sleeve. The spindle cutter includes a spindle extending into the annular sleeve and rotatable about a central axis of the annular sleeve, a base portion positioned between the retainer and a proximal end of the annular sleeve, and a cutter portion coupled to the spindle. The rotating cutter further includes at least one pin disposed between adjacent tabs of the plurality of tabs of the retainer to prevent axial movement of the base portion through the retainer.

Abstract: A method to drill a wellbore includes positioning a cutting structure proximal to a distal end of a drilling string, deploying a bottom hole assembly through a central bore of the distal end of the drilling string and the cutting structure, engaging the cutting structure with the bottom hole assembly, and rotating the cutting structure with the bottom hole assembly. An under reamer assembly includes a reamer shoe positioned proximal to a distal end of a drilling string and a cutting structure coupled to the reamer shoe, wherein the cutting structure is configured to be engaged by a bottom hole assembly, and wherein the cutting structure is configured to enlarge a pilot bore cut by a drill bit of the bottom hole assembly.

Abstract: Earth-boring tools comprise a face and a plurality of cutting elements disposed on at least a portion of the face. An impact material is positioned on at least one portion of a body and has a relative exposure equal to or greater than at least some of the cutting elements of the plurality of cutting elements. The impact material comprises a material having a lower abrasion resistance than the body. Methods of making and methods of using such earth-boring tools.

Abstract: A computer implemented method, apparatus and computer program product for extending test coverage in a simulated multiple core integrated circuit. The simulator applies at a first time a first test vector on the simulated multiple core integrated circuit, the first test vector having a duration. The simulator may also apply a second test vector at a second time before the duration but substantially after the first time. The simulator can collect a response from the multiple core integrated circuit based on the first test vector and the second test vector.

Abstract: A method of forming one or more micro-displays includes forming a first portion of a seal ring overlying a device substrate and surrounding one or more device chips formed on the device substrate, forming a second portion of the seal ring overlying a transparent cover, forming a first layer overlying the transparent cover, plasma bonding the first layer to a second layer formed overlying the device substrate and the one or more device chips, and fusing the first and second portions of the seal ring together using a beam of electromagnetic radiation.

Abstract: This invention is an adapter that fits on a cellular phone that allows a plurality of batteries to be connected in parallel. More specifically, this invention is an adapter that allows a standard cellular telephone battery to be fitted on a phone in the same fashion that an extended capacity or “aux” battery would. The adapter has an aperture for accommodating a battery, as well as electrical connections which couple the battery contacts to the phone's electrical contacts. An end user can use this invention to power a phone. Additionally the device can be used in conjunction with a battery charger to charge a spare battery.

Abstract: A homograph filter and method which increase the probability that homographs are pronounced correctly in a speech synthesis system utilizes a filter engine operating in conjunction with a set of rules. The filter engine parses a textual sentence to extract any present homographs and applies a correct set of rules to the homograph, based on an optimal search algorithm. The engine then carries out any appropriate substitution of phonetic data. Rules are primarily based on syntactic analisis, based on a priori knowledge of how each homograph is used. The rule set is classified into different categories in order to optimize the search algorithm and to allow the rules to be modified and updated incrementally without effecting the engine construction and/or performance. The search algorithm utilizes syntactic analysis to achieve optimum results.

Abstract: A computer system having a peripheral bus and a digital signal processor (DSP) local bus interfacing to the peripheral bus via an extended bus interface circuit (EBIC). The DSP local bus is configured such that devices, which are typically two or more DSPs, electrically connected to the DSP local bus may transfer data to other devices connected to the DSP local bus regardless of data transfer activity of the peripheral bus. Moreover, as seen from the peripheral bus, the devices connected to the DSP local bus have the same arbitration level. However, as seen from the DSP local bus, each device connected to the DSP local bus has a unique arbitration level determined by the priority of the tasks executing on the respective devices, as determined by a DSP operating system.
