20100300766Convex Crested Insert With Deflected Wedge Surfaces - This invention relates to carbide inserts used on roller cone bits for oil and gas drilling applications as well as for other geological drilling applications, and more specifically, relates to the convex crested insert with deflected wedge surfaces. The insert comprises a cylindrical portion and a crest portion. Said crest portion is composed of a conical crest base, a top surface and two opposing wedge surfaces. Upper ends of the two wedge surfaces are merged smoothly with top surface of the insert. The specific feature of the structure is that top surface of the crest portion is convexed outwardly and forms a smooth curve surface which is higher in the middle and lowers down gradually to each end. Said two wedge surfaces are slant wedge surfaces, so that a width of the top surface and therefore a width of the insert crest are tapered from one end to the other. Advantages of this invention include: 1. Help for rock breaking and therefore, it can increase drilling efficiency of the cutters and lower the overall drilling cost; 2. higher anti-breakage capability and longer working life; and 3. when inserts of this invention are used as heel row cutting elements on bit, contact area between wider end of the top surface of the insert and borehole wall is larger and therefore the gouging action applied on the borehole wall is higher and can also achieve better gage protection of the bit.12-02-2010

20100138729Pseudorandom binary sequence checker with control circuitry for end-of-test check - Control circuitry is coupled between an error event output and a data input of a pseudorandom binary sequence (PRBS) checker. The control circuitry is configured to switch between a first operating state in which a received PRBS signal is applied to the data input of the PRBS checker and a second operating state in which an error signal is applied to the data input of the PRBS checker, responsive to detection of a designated condition of the PRBS checker. In an illustrative embodiment, the designated condition is an end-of-test condition indicating that the PRBS checker has completed a test involving the received PRBS signal.06-03-2010
20100262671Delay Parameter Testing for Multiple-Device Master-slave Configuration Using a Single-Device Testing System - Devices to be arranged in a master-slave configuration are individually tested using a testing system that ensures that the devices will satisfy an interconnection requirement of that configuration. The testing system configures a first device into one of a master mode of operation and a slave mode of operation, and adjusts frame starting positions of respective traffic flows associated with the configured mode until measured delay parameters of that mode substantially match corresponding ones of a selected set of prospective delay parameters. If the traffic flows of the one configured mode as adjusted are substantially error free, the first device is configured into the other mode, and frame starting positions of respective traffic flows associated with the other configured mode of the first device are adjusted until measured delay parameters of that mode substantially match corresponding ones of the selected set of prospective delay parameters. If the traffic flows of the other configured mode as adjusted are substantially error free, the first device is identified as satisfying the interconnection requirement.10-14-2010
