Abstract: A graphically based tool and method for generating programming for a fire monitoring system. The locations of existing devices, such as detectors, in a building being monitored, can be visually presented in the context of the building. New devices can be installed, or the location of existing devices changed since all devices report their locations in the building to the tool. Device location information can be combined with building information to create a multi-dimensional representation of parts of the building being monitored.

Abstract: This technology relates materials that are stab, spike and ballistic resistant and to stab, spike and ballistic resistant composite articles incorporating uniaxially oriented, non-woven fabrics. A fabric layer having a non-uniform areal density is formed having thick areas and thin areas, the thick areas having a greater filament/tape concentration compared to the thin areas. In said thick areas, agglomerated tapes/filaments will protrude from the fabric layer surface. Additional layers are then adjoined with the non-uniform layer to form a panel that has stab, spike and ballistic resistance, with protrusions at least partially spacing the additional layers from full, direct contact with the surface of the non-uniform fabric layer to thereby enhance flexibility and stab, spike and ballistic resistance of the whole.

Abstract: Techniques for detecting motion of a vehicle are disclosed. Optical flow techniques are applied to the entirety of the received images from an optical sensor mounted to a vehicle. Motion detection techniques are then imposed on the optical flow output to remove image portions that correspond to objects moving independent from the vehicle and determine the extent, if any, of movement by the vehicle from the remaining image portions. Motion detection can be performed via a machine learning classifier. In some aspects, motion can be detected by extracting the depth of received images in addition to optical flow. In additional or alternative aspects, the optical flow and/or motion detection techniques can be implemented by at least one artificial neural network.
