Abstract: A system and method for simultaneously reading a plurality of readable memory-based digital identification devices, including: a host microcontroller; and a plurality of readable memory-based digital identification devices electrically coupled to the host microcontroller in a parallel configuration; wherein the host microcontroller is configured to assert a read prompt to each of the plurality of the plurality of readable memory-based digital identification devices during a same clock cycle; wherein each of the plurality of readable memory-based digital identification devices is configured to send a response to the host microcontroller in a same clock cycle; and wherein the host microcontroller is configured to capture identification data from each of the plurality of readable memory-based digital identification devices in a same clock cycle.

Abstract: A system and method for protection of virtual connections at the data link layer. The method provides for protection switching in a ring network. The method comprises detecting an error in one of a first and second routes (“the errored route”). Error cells are generated for each virtual connection affected by the detected error. Error cells are transmitted downstream on the errored route. First switch fabric receives the error cells at a downstream network element associated with the errored route. Change in state of the errored route is communicated to a second switch fabric of the downstream network element associated with the other of the first and second routes (the “other route”). When the state of the errored route is worse than the state of the other route, automatically configuring the second switch fabric to establish the other route to be a working route for the virtual connection.

Abstract: An improved foundation vent with increased net free area is provided. The foundation vent has a frame that surrounds and defines an opening and a grill supported by the frame and spanning the opening. The grill has an inside face disposed on the inside of a crawlspace when the vent is mounted in a foundation wall and an outside face disposed on the outside of the crawlspace. A mesh screen is mounted to the frame and spans the opening adjacent the inside face of the grill. The grill is provided with projecting standoffs that support the screen at a predetermined distance from the inside face of the grill to form a plenum between the screen and the grill. A raised peripheral rim is provided on the frame and supports the peripheral portion of the screen. The spacing of the screen from the inside face of the grill and the plenum formed thereby unblocks the portions of the screen that otherwise would be blocked by the members of the grill and thus increases the net free area of the foundation vent.
