Abstract: Alert directives and focused alert directives allow a user to provide feedback to a behavioral recognition system to always or never publish an alert for certain events. Such an approach bypasses the normal publication methods of the behavioral recognition system yet does not obstruct the system's learning procedures.

Abstract: Magnetoresistive device architectures and methods for manufacturing are presented that facilitate integration of process steps associated with forming such devices into standard process flows used for surrounding logic/circuitry. In some embodiments, the magnetoresistive device structures are designed such that the devices are able to fit within the vertical dimensions of the integrated circuit associated with a single metal layer and a single layer of interlayer dielectric material. Integrating the processing for the magnetoresistive devices can include using the same standard interlayer dielectric material as used in the surrounding circuits on the integrated circuit as well as using standard vias to interconnect to at least one of the electrodes of the magnetoresistive devices.
