Abstract: There is provided a simulation-based Computer Generated Force (CGF) system for tactical training in a training field including a receiver for receiving information on the training field, a database for storing a library of CGF behaviours for one or more robots in the training field, a CGF module, coupled with the receiver and the database, for processing the information on the training field and selecting a behaviour for each of the one or more robots in the training field from the library of CGF behaviours stored in the database, a controller, coupled with the CGF module, for sending commands based on the selected behaviours to the one or more robots in the training field. The information on the training field includes location of one or more trainees and the commands include shooting the one or more trainees.

Abstract: One embodiment of the disclosure is a method for changing a cutting ability of an abrasive device. The method includes abrading a portion of an abrasive device, thereby reducing a cutting ability of the abrasive device. Moreover, the method includes heating the abrasive device to fuse materials therein, thereby increasing a cutting ability of the abrasive device. Another embodiment of the disclosure includes a method for treating an abrasive brush having a plurality of bristles, each bristle having a distal tip; the method includes rotating the brush so that a plurality of bristle tips contact a hot plate. The disclosure also describes an apparatus for increasing a cutting ability of a used abrasive device, the apparatus comprising a heating element to fuse materials of the abrasive device.

Abstract: A molded brush segment having a plurality of integrally molded bristles extending from a generally planar center portion. The brush segment is molded from a moldable polymer, such as a thermoplastic elastomer, and has a plurality of abrasive particles present in at least the bristles of the brush segment.
