Abstract: An integrated wing-shaped heavy bag is illustrated and described. The heavy bag comprises an elongated body having a hollow receiving space and at least one integrated punching/striking wing disposed at a lateral perimeter. A unitary casing facilitates integration of the wing with the elongated body through continuously transitioned adjoining edges and/or strengthening contours. A wing insert is disposed in and substantially fills a wing cavity of the heavy bag. The wing insert is secured internally to the unitary casing by a fastener which minimizes shifting of the wing insert with respect to the wing cavity and the unitary casing.

Abstract: Collision sensing devices connect to a main unit housing a plurality of electronics which include a cellular telephone circuit, a GPS receiver, and a compass circuit. Once a collision is detected, real-time geographical position and heading data are captured and sent to an emergency alert center where the data may be analyzed to determine the location of the vehicle in distress. Meanwhile, intense visual signals are transmitted from the exact location of the accident. The Vehicle Collision Detector also functions as a means for counterterrorism.
