Abstract: A signal processing system includes a random decision forests-based bulk filter. The signal processing system further includes one or more sensors (e.g., radar systems, satellite systems) that interface with the signal processing system via a radio frequency (RF), electro-optical (EO) or infrared (IR) exchange process, a computationally inexpensive object detector, a computationally inexpensive state estimator, then the random decision forests-based bulk filter, a computationally expensive object tracker, a computationally expensive object discriminator, and a report. Further, the random decision forests-based bulk filter features a filter training optimization process.

Abstract: A method and apparatus for firing a plurality of disrupter loads in arbitrary order at the discretion of the user is disclosed. The loads may be of the same or different types. Both liquid and solid projectiles may be fired. Further, the disrupter may be operated by a user at safe standoff distance from a robotic mount with the aid of control, targeting, ranging and recoil systems.

Abstract: Methods and apparatus for detecting the presence of electronic communications devices, such as cellular phones, are disclosed. In an exemplary method, a complex radio frequency stimulus is transmitted into a target area, and nonlinear reflection signals received from the target area are processed to obtain a response measurement. The response measurement is compared to a pre-determined filter response profile to detect the presence of a radio device having a corresponding filter response characteristic. In some embodiments, the pre-determined filter response profile comprises a pre-determined band-edge profile, so that comparing the response measurement to a pre-determined filter response profile comprises comparing the response measurement to the pre-determined band-edge profile to detect the presence of a radio device having a corresponding band-edge characteristic.
