Abstract: A prosthetic device for use as an artificial meniscus is disclosed. The prosthetic device restores stress distribution, stability, and function to the knee joint after removal of the damaged natural meniscus. In some embodiments, the prosthetic device includes an anti-migration feature that inhibits extreme movement within the joint while permitting free floating over a significant range. In one aspect, the anti-migration feature is an enlarged anterior structure or a posterior meniscus remnant engaging channel while in another aspect, the anti-migration feature includes a tethering member. Still further, removable radiopaque features are provided to enhance trialing of the implant prior to final implantation within the joint.

Abstract: A portable target locator for use by a ground observer to accurately determine the location of a target and transmit location information and firing instructions to an unmanned vehicle so the unmanned vehicle can locate the target and perform an operation based on the firing instructions. The apparatus comprises optics for permitting a user to see a magnified view of the target; a location determining component for determining a location of the apparatus; rangefinder for determining a range from the apparatus to the target; an Azimuth sensor for determining an Azimuth from the apparatus to the target; a processor for determining the location of the target based on the location of the apparatus, the range to the target, and the Azimuth from the apparatus to the targets, a transmitter for transmitting the location information and the firing instructions to the unmanned vehicle, and a portable handheld housing.
