Abstract: A common gate input circuit for III/V D-mode Buffered FET Logic (BFL) maximizes the dynamic range to drive a level shift section to set the proper voltage levels to switch the BFL and allows for decoupling of the switch point from the dynamic range. A common gate switching section includes a D-mode FET (FET1) configured as a load and a D-mode FET (FET2) configured as a common gate connected in series between high and low supplies Vdd and Vee1 (typically ground potential). The gate electrode of FET2 is coupled to Vee1 and the source electrode of FET2 is driven by the external digital signals. This eliminates the additional supply Vss, thus maximizing the dynamic range of the section to switch between Vdd and Vee1 and decouples the dynamic range from the switch point. An input level shift section may shift the Data In to the source electrode of FET2 to shift the switch point and to present a high input impedance.

Abstract: A sight frame assembly for a weapon simulator includes one or more connection arms. The connection arms are for slidably coupling the sight frame assembly to the weapon simulator. The connection arms include a passageway for slidably receiving a guide rod that is attached to a sight frame assembly mounting point on the weapon simulator. A spring is positioned in proximity to the guide rod. The sight frame assembly is disposed in a first position along a longitudinal axis of the weapon simulator when the spring is in an uncompressed state, and the sight frame assembly is disposed in a second position along the longitudinal axis of the weapon simulator when the spring is in a compressed state.

Abstract: A system includes a substrate. The system also includes a detector array disposed over the substrate, where the detector array includes multiple detector pixels. The system further includes multiple plasmonic gratings disposed over top surfaces of the detector pixels, where each plasmonic grating includes multiple convex polyhedrons separated by valleys. Each detector pixel may have a mesa shape, and the convex polyhedrons of the plasmonic gratings may have a smaller size than the mesa shape of the detector pixels. A dimension across a base of each convex polyhedron of the plasmonic gratings may be selected based on a desired resonance wavelength of the plasmonic gratings.

Abstract: A method of controlling access to a network includes receiving, from a node, a request to access the network. A challenge is sent to the node, the challenge configured to elicit a node fingerprint from the node. The node fingerprint is based on the challenge and on unique characteristic data of a physically unclonable function (PUF), at the node. An expected fingerprint is generated for the node based on the challenge and on characteristic data information associated with the unique characteristic data of the PUF. The characteristic data information is accessed from a location that is independent of and separate from the node. The node is authenticated to the network, to allow the node to access to the network, if the received node fingerprint matches the expected fingerprint. The first node is denied any access to the network if the received node fingerprint does not match the expected fingerprint.

Abstract: Techniques for multi-factor pathfinding are disclosed. A system receives multiple data sets that represent multiple physical properties associated with multiple three-dimensional coordinates of a physical environment. The system generates multiple weighted data layers corresponding to the physical properties, at least by applying weights to the data sets. The system generates a multi-factor costmap for the three-dimensional environment, based at least on the weighted data layers. The system determines a path through the three-dimensional environment, based at least on the multi-factor costmap.
