Abstract: A tracking computer system may track a target using a single linear array. The system may receive first sensor measurements and one or more additional sensor measurements from the linear array. The system may determine whether a location of the target can be identified based on a cone intersection algorithm. When the target location can be identified based on the cone intersection algorithm, the first and the one or more additional sensor measurements may be applied to the cone intersection algorithm to identify the target location. When target location cannot be identified based on the cone intersection algorithm, the first and the one or more additional sensor measurements may be applied to an angular motion model to determine a best fit arc path corresponding to the target. A true target angle estimate and a target angular velocity may be determined based on the determined best fit arc path.

Based on the IR portion, a virtual image is displayed on an interior surface of the lens so that the virtual image overlays the IR portion.

Abstract: A computer-implemented method for processing radar return signals to identify spherical objects from within a cluster of objects, collects by a radar receiver, a plurality of radar return signals over N-point measurement windows corresponding to objects within the cluster of objects, the radar return signals corresponding to electronic pulses transmitted by a radar transmitter.

Abstract: Monoclonal antibodies, which can be produced in vitro, against cardiac epitopes of the human My-C are produced by generating myeloma cell clones that produce such specific antibodies having epitope specificity. These monoclonal antibodies allow, among other things, the creation of an enzyme-linked immunosorbent assay (ELISA) for the specific, cross-reactivity-free quantitative determination of My-C in serum, plasma, whole blood or other body fluid. Specifically, a hybridoma cell clone producing a monoclonal antibody that detects and binds a cardiac epitope in the My-C is produced, which has no cross-reactivity with respect to the myosin-binding proteins of the skeletal muscles. The hybridoma cell line can be obtained by fusing myeloma cells with spleen cells of a test animal, in particular a mouse, immunized against recombinant My-C.
