Abstract: A night vision system along with an image intensifier tube having a microchannel plate and method of forming the microchannel plate are provided. The microchannel plate comprises a plurality of spaced channels extending through the microchannel plate, wherein each channel sidewall surface near the input face of the microchannel plate comprises a series of layers formed thereon. The input face of the microchannel plate, as well as the sidewall surfaces of each channel near the input surfaces, are configured with an electron backscatter layer arranged between a contact metal layer and a secondary electron booster layer. When formed partially into the channel openings near the input face, the electron backscatter layer and overlying secondary electron booster layer are configured circumferentially around the sidewall surfaces and extend radially inward toward a central axis of each channel.

Abstract: Systems and methods for blocking spoofed traffic within communications networks include obtaining, at a computing system, routing information for an autonomous system of a communications network, the routing information identifying Internet Protocol (IP) addresses associated with the autonomous system. In response to receiving the routing information, the computing system generates a prefix list based on the routing information, the prefix list including one or more prefixes encompassing the IP addresses identified by the routing information. The computing system then transmits instructions to a network device of the communications network configured to cause the network device to update a filter function of the network device based on the prefix list such that the network device permits network traffic that originates from IP addresses within the prefixes of the prefix list.

Abstract: Systems and methods for network-based ultrasound imaging are provided, which can include a number of features. In some embodiments, an ultrasound imaging system images an object with three-dimensional unfocused pings and obtains digital sample sets from a plurality of receiver elements. A sub-set of the digital sample sets can be electronically transferred to a remote server, where the sub-set can be beamformed to produce a series of two-dimensional image frames. A video stream made up of the series of two-dimensional images frames can then be transferred from the remote server to a display device.

An optical fiber extends within the hollow flexible shaft substantially along the central axis. A distal tip of the optical fiber is attached to the hollow flexible shaft and aligned with the imaging window so as to transfer an optical coherence tomography signal through the imaging window. A handle is attached to the hollow flexible shaft configured rotate the hollow flexible shaft at speeds of greater than 1,000 rpm.

Abstract: Aspects of the present disclosure involve systems, methods, computer program products, and the like, for providing multiple egress points from a telecommunications network for a client of the network. In particular, the process and system allows for multiple provider edges of the network to utilize a route reflector server to provide a border gateway protocol (BGP) route to other provider edges in the network. Further, the multiple provider edges may each announce similar interior gateway protocol (IGP) routes through the network such that a provider edge receiving a packet intended for the customer network may select from the multiple IGP routes to provide the intended packet to the customer network. In this manner, the receiving provider edge may load balance among the various connections of the customer network to the telecommunications network.

Abstract: A primary subsystem captures original information and supplemental information to form a revision. A primary subsystem enables revisions to be made at the location of the incident prior to leaving the location. Systems for collecting and managing information about incidents include primary and secondary subsystems. A category is a descriptor or label that identifies a common aspect among members assigned to the category. Categories may determine how information is stored, communicated, and/or accessed on primary and/or secondary subsystems.

Abstract: An adjustable bed base has a subframe which may be raised and lowered relative to a stationary frame by primary linear actuators. A deck is attached to the subframe. The deck may be flat or fully articulated depending upon the position of secondary linear actuators which are a part of a subframe module. The subframe module may be secured to the stationary frame of the adjustable bed base. The deck may be inclined by extending one of the primary linear actuators more than the other regardless of the positions of the deck members.

Abstract: A neuromodulation therapy is delivered via at least one electrode implanted subcutaneously and superficially to a fascia layer superficial to a nerve of a patient. In one example, an implantable medical device is deployed along a superficial surface of a deep fascia tissue layer superficial to a nerve of a patient. Electrical stimulation energy is delivered to the nerve through the deep fascia tissue layer via implantable medical device electrodes.

Abstract: A tissue thickness compensator may generally comprise a compressible core comprising a plurality of movable particles, and a wrap surrounding the compressible core. The plurality of movable particles may comprise at least one medicament. A tissue thickness compensator may generally comprise a compressible core comprising a plurality of crushable particles, and a wrap surrounding the compressible core. The plurality of crushable particles may comprise at least one medicament. The compressible core may comprise a material selected from a group consisting of a biocompatible material. The wrap may comprise a material selected from a group consisting of a biocompatible material. Articles of manufacture comprising the tissue thickness compensator and methods of making and using the tissue thickness compensator are also described.

Abstract: Instruments and surgical techniques may be used to correct a bone deformity, such as a bunion in which a metatarsal is misaligned with respect to a medial cuneiform. In some examples, a bone cutting guide is utilized to cut an end of the metatarsal and/or an end of the medial cuneiform to facilitate realignment of the bones. The cutting guide can have a pivotable cut guide surface along which a cutting instrument is translated to provide a precise bone cut. In some applications, after suitably preparing and aligning the bones, the bones are compressed together using a fixation pin. The fixation pin can be driven through one of the bones, into the second bone, and then further driven to compress the bones together.
