Abstract: Methods and systems for vehicle safety lighting are disclosed, including a system having a multi-axis accelerometer that detects acceleration of the vehicle along a first axis and a second axis normal to the first axis, and outputs a corresponding first axis acceleration measurement and a second axis acceleration measurement. A controller is coupled to the multi-axis accelerometer, and to an array of light emitter elements (LELs). The controller is configured to determine a vehicle deceleration, based at least in part on a combination of the first axis acceleration measurement and second axis acceleration measurement, and to detect the vehicle deceleration exceeding a brake light threshold and, based at least in part on the detection, output a deceleration light signal to the array of LELs.

Abstract: Scrap plastic is treated for incorporation into asphalt-aggregate compositions by first shredding the plastic, then heating the shredded plastic to harden any pieces of film or flexible plastic and to generally reduce the size of the shreds without decomposing the plastic, and then grinding the heat-treated pieces to a size that can be blended with an aggregate. The blend is then combined with an asphalt binder to produce an asphalt-aggregate composition. No discrimination among, or selection of, specific types or classes of plastic is required.
