Abstract: A bolt carrier speed control apparatus that is configured to provide adjustable speed control of the bolt carrier during firing of a round of ammunition. The bolt carrier speed control apparatus is configured to be mounted in a first location or a second location. The bolt carrier speed control apparatus includes a body that is cylindrical in form. The body includes and interior volume and further includes a central bore extending longitudinally therethrough. Circumferentially disposed around the central core are a plurality of movement assemblies. The movement assemblies are configured to move in an inward-outward direction that is facilitated by traversal of an adjustment screw through the central bore. The movement assemblies include a wall engagement member that is configured to extend beyond the external surface of the body so as to engage a portion of the firearm and provide speed control of the bolt carrier through added friction.

Abstract: Systems and methods for image alignment are disclosed. A method includes: determining a first set of patches for a first image and a second set of patches for a second image, wherein each patch in the first and second sets of patches comprises a portion of the first and second image, respectively; determining a set of possible match pairings of a patch from the first set and a patch from the second set; for each match pairing in the set of possible match pairings, computing a transformation operation to align the patch from the first set of patches and the patch from the second set of patches in the match pairing; grouping the match pairings into clusters based on parameters of the transformation operations of the match pairings; and, performing the transformation operation corresponding to at least one cluster to align the first image to the second image.

Abstract: A touch sensor is associated with a housing that is adapted for attachment to the outer perimeter of a fluid conduit. The housing can be attached to the fluid conduit such that the touch sensor can detect the presence of fluid within the fluid conduit. The output of the touch sensor can be used by an indicator or processor.

Abstract: An apparatus is disclosed in a first embodiment of the invention as including a non-conductive substrate providing a first surface onto which a user can apply a fingerprint. A fingerprint sensing circuit is applied to a second surface of the non-conductive substrate opposite the first surface. The fingerprint sensing circuit is capable of sensing a fingerprint through the non-conductive substrate. A navigation device is positioned adjacent to (e.g., below) the non-conductive substrate and is capable of being manipulated by the user through the non-conductive substrate.

Abstract: A method and device for compressing a fingerprint template is provided. The fingerprint template is derived from fingerprint image data captured from a sensor. The compressing process initially surveys the fingerprint template to determine one or more starting points for encoding. Subsequently, the compression process selects a starting point from the one or more starting points and proceeds to encode that starting point. After encoding the starting point, the compression process encodes all contours extending from the selected starting point. The above process is repeated until all starting points and their associated contours have been encoded.

Abstract: Systems and methods performed by an IP telephony system are designed to determine when two parties to a recently terminated telephony communication are simultaneously calling each other in an attempt to re-establish a telephony communication. When the IP telephony system determines that this situation is occurring, the IP telephony system acts to connect the two parties, rather than have both of them see their new call setup attempt fail because the other party's telephony device is indicated to be busy.
