Abstract: One variation of a method for monitoring an object during a presentation, includes: initiating capture of a video with a camera defining a field of view, the camera arranged on a first side of a mobile computing device supported on a base device; generating a position signal defining a position of the remote device relative to the camera; in response to wirelessly receiving a first input selection from the remote device, indexing through digital slide content rendered on a display arranged on the first side of the mobile computing device; in response wirelessly receiving sensor data from a remote device coupled to the object, generating an event tag including a timestamp; and generating a multimedia stream including the video, the position signal data, digital slide content, the first input selection, and the event tag.

Abstract: A dual combustion fastener device implements a first combustion event, contained in a first combustion chamber portion to compress a combustible fuel/air mixture contained in a second combustion chamber portion, which is separated from the first combustion chamber portion by a piston including a driver for driving a fastener disposed in the driver's path of travel into a workpiece, in order to generally provide rapid driving power for securing a fastener disposed in a nose guide of the combustion fastener. Ignition of the second combustion event may be timed so that the second combustion event substantially occurs when the piston has achieved top dead center or the maximum compression of the combustible material in the second combustion chamber portion. Utilization of compressed combustible material may allow for the utilization of a piston having a small cross-sectional area in comparison to a typical combustion device while providing equal or greater driving force in a rapid manner.
