Abstract: Methods and systems for welding contacts of a plurality of battery cells are provided. A method includes using a detector to perform a scan of the cell electrode contact area for each of the plurality of battery cells. Based upon the scan of each cell electrode contact area, a determination is made of whether one or more possible weld sites for each electrode contact area are viable for welding. In response to determining that one or more weld sites are viable, one or more of the viable weld sites are selected and a welder is used to weld at least one of the selected weld sites.

The firearm further has a firing pin with a striking end that has a cylindrical shape and a substantially sharp shoulder. A hammer is also provided with a depression disposed in a front surface thereof, the front surface configured to strike the striking end of the firing pin when the upper receiver is next to the lower receiver, and the depression configured to align with the striking end of the firing pin when the upper receiver rotates away from the lower receiver.

Abstract: A gun smith platform includes a top plate. The top plate has a tool hole centrally disposed on the top plate that extends through the top plate through which a work piece attached to a work tool mounted to a bottom side of the top plate may extend, a plurality of alignment holes extending in a linear pattern from the tool hole, the alignment holes configured to receive alignment pins, at least one row of threaded mounting holes disposed parallel to the linear pattern of alignment holes, and a recessed track disposed parallel to the at least one row of threaded mounting holes. Four legs are attached to and supporting the top plate.

Abstract: A firearm and a jig for modifying or constructing a firearm with a locking magazine release button is provided. The firearm has a lower receiver including a magazine locking pin aperture disposed in an upper surface thereof where the magazine locking aperture intersects with a magazine release button aperture in a side surface of the lower receiver. The firearm also has an upper receiver attached to the lower receiver via a pivot pin, a magazine attachable to the lower receiver, a magazine locking pin inserted into the magazine locking pin aperture, and a magazine release button comprising a recessed locking catch. The magazine release button releases the magazine when the upper receiver is away from the lower and the pin is not in the magazine locking aperture. The button is inoperable when the upper receiver is next to the lower receiver and the pin engages the locking catch.

Abstract: A method and apparatus for offset detection and correction is disclosed. In an active amplifier or filter system, or any system that may suffer from unwanted offset, the invention monitors for periods when an input, i.e. reference value, may be predicted or is known. When such a period is detected, the offset detection and correction system records the offset and compares it to the known or predicted reference value. Based on the comparison the amount of offset can be determined. In one configuration, the offset is determined to be greater than or less than the reference value. A digital value is thus provided to correction logic to control an output value. This output value increments or decrements a counter. The output of the counter feeds into a digital to analog converter. The output of the digital to analog converter is provided by into the system that suffers from offset to correct or counter the unwanted offset.
