io Automated pointing and control of high resolution cameras using video analytics By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT An automated method for cueing a high resolution video camera to a mobile object involves first detecting the presence of an object by a wide-area surveillance asset such as a radar and using the radar's positional information to cue the video camera iteratively, while updating the positional information each time. Then, a video analytics algorithm detects the object and generates more accurate positional and rate information on the object, which is then used to cue the video camera into a higher resolution setting for classifying/identifying the object. Once the object is identified, the positional and rate information is updated and the updated information is used to further cue the video camera into a higher resolution setting for recording a video clip of the moving object while the video camera is dynamically steered.

io Device and method for controlling compression of tissue By www.freepatentsonline.com Published On :: Tue, 28 Apr 2015 08:00:00 EDT A method and device for controlling the compression of tissue include clamping tissue between a first clamping member and a second clamping member by driving at least one of the clamping members with an electric motor toward a predetermined tissue gap between the clamping members and, during the clamping, monitoring a parameter of the electric motor indicative of a clamping force exerted to the tissue by the clamping members. The method and device include, during the clamping, controlling the electric motor, based on the monitored parameter, to limit the clamping force to a predetermined maximum limit. Full Article
io Varying tissue compression with an anvil configuration By www.freepatentsonline.com Published On :: Tue, 28 Apr 2015 08:00:00 EDT The present disclosure relates to surgical fastener applying apparatus and the application of variable compression to tissue. More specifically, the presently disclosed surgical fastener applying apparatus act to limit the flow of blood through tissue immediately adjacent a cut-line formed therein to effectuate hemostasis, while maximizing the flow of blood through tissue more removed from the cut-line to limit unnecessary necrosis. In one embodiment, a surgical fastener applying apparatus is disclosed having a tool assembly coupled to a distal end thereof with first and second jaws respectively including an anvil and a surgical fastener cartridge. The surgical fastener cartridge includes, among other things, angled pushers that engage surgical fasteners of varying lengths. Full Article
io Staple cartridge comprising compressible distortion resistant components By www.freepatentsonline.com Published On :: Tue, 28 Apr 2015 08:00:00 EDT A fastener cartridge can comprise a support portion, a tissue thickness compensator positioned relative to the support portion, and a plurality of fasteners positioned within the support portion and/or the tissue thickness compensator which can be utilized to fasten tissue. In use, the fastener cartridge can be positioned in a first jaw of a surgical fastening device, wherein a second jaw, or anvil, can be positioned opposite the first jaw. To deploy the fasteners, a staple-deploying member is advanced through the fastener cartridge to move the fasteners toward the anvil. As the fasteners are deployed, the fasteners can capture at least a portion of the tissue thickness compensator therein along with at least a portion of the tissue being fastened. Full Article
io Interlocking buttress material retention system By www.freepatentsonline.com Published On :: Tue, 28 Apr 2015 08:00:00 EDT A surgical stapler is provided having a pair of jaws including a staple containing cartridge and an anvil. Buttress material is releasable affixed to the staple containing cartridge and the anvil. One of the jaws includes a pair of longitudinal projections at a first end of the jaw and configured to frictionally engage corresponding slots in a first end the buttress material. One of the jaws includes a post at a second end of the jaw. The buttress material includes a hole in a second end of the buttress material for receipt of the post. Full Article
