Abstract: Metering dispensers include a body configured to hold a flowable composition in a chamber, a drive screw coupled to the body, and a plunger threadingly coupled to the drive screw. The plunger includes at least two annular lips that form a fluid seal with the chamber as the plunger travels along the drive screw through the chamber. A base is rotationally coupled to the body with a cam that contacts at least one tab extending externally from the body so that the tab enters at least one low point on the cam by traveling over a trailing edge of the low point, and the trailing edge then prevents the tab from exiting the low point in the direction of the trailing edge.

Abstract: Innovations in adaptive encoding and decoding for units of a video sequence can improve coding efficiency when switching between color spaces during encoding and decoding. For example, some of the innovations relate to adjustment of quantization or scaling when an encoder switches color spaces between units within a video sequence during encoding. Other innovations relate to adjustment of inverse quantization or scaling when a decoder switches color spaces between units within a video sequence during decoding.
Abstract: The present disclosure relates to optical systems and methods for their manufacture.

Abstract: This disclosure describes a novel, ready-to-use protease composition in the form of a film or pouch composition. The protease composition can be used for stabilizing a biological sample containing a nucleic acid molecule for storage or transportation. It allows quick removal of protein contamination in the biological sample, thus facilitating sample preparation for nucleic acid detection or extraction.
Abstract: A tool and an associated method for removing a prosthetic implant includes a lateral tool, a first impact tool secured to the lateral tool, a medial tool, and a second impact tool. Although the tool can be used to remove a variety of different prosthetic implants, it finds particular application in the removal of femoral implants. Both lateral and medial tools are utilized. The lateral tool includes a generally arcuate shape with upstanding sidewalls that define an arcuate interior. The lateral tool is thus dimensioned to follow the contour of the lateral side of a femoral implant. The medial tool includes opposing side walls that define an interior opening. The opening is sized to receive the neck of the femoral implant, thereby allowing the tool to closely follow the medial bone/implant interface.
Abstract: A firearm sight mounting plate assembly for a firearm is provided. The firearm sight mounting plate assembly includes a mounting plate.
