A test specimen support is joined to the moving assembly and disposed on one side of the stationary support so as to move along the axis with movement of the moving assembly, the axis extending through the test specimen support.

Abstract: A data diode provides a flexible device for collecting data from a data source and transmitting the data to a data destination using one-way data transmission across a main channel. On-board processing elements allow the data diode to identify automatically the type of connectivity provided to the data diode and configure the data diode to handle the identified type of connectivity. Either or both of the inbound and outbound side of the data diode may comprise one or both of wired and wireless communication interfaces. A secure reverse channel, separate from the main channel, allows carefully predetermined communications from the data destination to the data source.

Abstract: The current invention comprises a set of Door Jamb Jigs designed to enable the user to temporarily hold a carpenters level, a carpenters square, and a door jamb firmly within the rough opening of a framed wall so that the door jamb can be permanently nailed in place pre-squared, pre-leveled, and pre-plumb. The current invention utilizes universally designed Jigs that enable users to utilize their own conventional carpenters square and carpenters level combined with the Door Jamb Jigs to practice a new method of installing pre-hung interior doors much easer, faster and more accurately compared to the conventional practice of holding tools by hand. The current invention solves problems during the Pre-hung door jamb installation process. #1 The invention enables the user to temporarily attach both a 90 degree carpenters square and a carpenters level to the door jamb so when the door panel is reattached to the jamb the clearance between the door panel and the door jamb is equal and parallel all around.
