20110094373 | CONVERTIBLE GAS PISTON CONVERSION SYSTEM - A convertible gas piston conversion system for the AR-15, AR-10, or their variant rifle platforms is provided to convert the platform from a direct impingement gas system to a piston driven operating system. The conversion system includes a gas block having a barrel bore and two piston cylinder bores one on either side of the gas block. One of the piston cylinder bores is for utilization of the AR-15 rifle and the other of the piston cylinder bores is for utilization of the AR-10 rifle, making this piston system convertible for either the AR-15, AR-10, or any of their variant rifle platforms. A piston cylinder is inserted into the gas block via the piston cylinder bore and a piston is actuated inside the piston cylinder to cycle the rifle. A connecting link is coupled between the piston and an op-rod making the gas systems length adjustable by simply replacing the connecting link. The op-rod acts directly upon a carrier lug to cycle the rifle and a compression spring or the like returns the piston back into the battery within the piston cylinder. An op-rod bushing guides the op-rod throughout travel. A bolt carrier includes a lug and an anti tilt/anti wear device. The bolt carrier provides a lug for the op-rod to impinge upon to cycle the rifle. The anti tilt/anti wear bolt carrier device installs into the rear of the bolt carrier to minimize damage and wear to the buffer tube and upper receiver from a condition identified as carrier tilt. | 04-28-2011 |
20130055883 | MULTI-BLOCK GAS REGULATOR - A multi use retro fit capable adjustable gas block designed to interface with an autoloading gas operated firearm is provided to replace existing gas blocks. The adjustable gas block optimizes gas flow into the host firearms operating system. The adjustable gas block has a spring loaded adjustment knob that releases when pulled forward allowing it to rotate. By rotating the adjustment knob the gas flow is increased or decreased based on one of four provided gas settings. Setting one is optimal for using a silencer, setting two is optimal for normal operations, setting three is optimal for adverse conditions, and setting four either turns the gas flow off optimizing sound reduction and providing for manual operation, or provides an extra high gas setting for the host firearm. The system works by precisely metering gas entering the operating system and not by exhausting excess gas into the atmosphere. The adjustable gas regulator may be configured with a piston operating system or a direct gas impingement operating system, e.g. gas tube, as is the case with the standard AR-15/AR-10 family of firearms. | 03-07-2013 |

20090063068 | NUMERICAL TEST DATA REPORTING IN AN IMAGE FILE AND SUBSEQUENT ANALYSIS - The present disclosure is directed to numerical test data reporting using an image file and subsequent analysis of the test data. A method for capturing and analyzing test data in accordance with an embodiment includes: capturing multi-bit integer values of test data; writing each multi-bit integer value to a multi-bit vertical field in an image file; extracting the multi-bit integer values from the multi-bit vertical fields in the image file; and analyzing the extracted multi-bit integer values. | 03-05-2009 |
20090129185 | SEMICONDUCTOR CIRCUITS CAPABLE OF SELF DETECTING DEFECTS - A digital circuit and a method for operating the same. The digital circuit includes (a) M×N regular cells electrically arranged in M rows and N columns, (b) N reference cells corresponding one-to-one to the N columns, and (c) N comparing circuits corresponding one-to-one to the N columns. Each regular cell is electrically coupled to a comparing circuit. Each reference cell is electrically coupled to the associated comparing circuit. Each regular cell includes a first tap node. Each reference cell includes P tap nodes. If a first voltage of the first tap node of a regular cell is between two voltages of two tap nodes of the P tap nodes of the associated reference cell, then the associated comparing circuit is capable of generating a first signal. If the first voltage is not between the two voltages, then the associated comparing circuit is capable of generating a second signal. | 05-21-2009 |
20120139574 | VERTICAL PROBE TIP ROTATIONAL SCRUB AND METHOD - A vertical probe tip rotational scrub and method is described. The vertical probe includes a wafer prober chuck; a wafer positioned on the wafer prober chuck; and at least one probe having a probe tip, the at least one probe tip rotatably mounted such that the probe tip provides a rotational scrub on a surface of a wafer surface. A method for wafer probing is also described, the method includes: determining a vertical location of a wafer surface relative to at least one probe having a probe tip; retracting the probe tip; and imparting an upward motion on the at least one probe in response to the retracting of the probe tip, wherein the upward motion results in a rotational scrub of the wafer surface. | 06-07-2012 |
