Abstract: A helmet with an airbag assembly coupled to the shell of the helmet. The airbag assembly includes an airbag and an inflation device. The inflation device is configured to at least partially inflate the airbag upon deployment of the airbag assembly. The helmet also includes a processing circuit disposed at least partially within the shell. The processing circuit is configured to receive helmet data regarding a second helmet, transmit deployment data regarding inflation of the airbag assembly, and control operation of the inflation device to inflate the airbag based on the helmet data.

Abstract: A force balanced irregular pitch reamer is provided that is particularly well suited for precision operations requiring small tolerances. More specifically, a reamer is provided having a shank, a body portion, and a plurality of cutting teeth extending outwardly therefrom. The teeth are spaced at non-uniform intervals around the body portion, wherein each tooth includes a cutting surface and rake face, and defines a rake angle between the rake face and an imaginary line extending from the central or longitudinal axis of the reamer to the cutting surface. In operation, the reamer is rotated about its central axis and is plunged into a formed hole sized slightly smaller than the reamer such that the reamer engages the workpiece and produces a smooth finished hole. Each tooth generates a cutting force with determinable magnitude and direction to define cutting force vectors.

Abstract: Apparatus for aligning a document, the apparatus comprising: structure for feeding a document in a downstream path of travel, the document have a downstream edge relative to the path of travel; structure for registering the downstream edge of a document in a direction extending transverse to the path of travel, the registering structure including at least one member extending into the path of travel, the registering structure including structure for moving the at least one member downstream in the path of travel; and structure for controlling the feeding structure to urge a document into engagement with the at least one moving member.
