Abstract: Consensus vehicular collision properties determination is provided by a method that receives mobile device sensor data from mobile device(s) of vehicle occupant(s). The vehicle is a vehicle of multiple vehicles involved in a collision, and the sensor data indicates movement and position information pertaining to the collision. The method shares the packaged sensor data to a decentralized ledger that stores this as part of a collection of sensor data from across multiple mobile devices of different vehicle occupants in the vehicles involved in the collision. Extraction and correlation of data from the ledger is used to determine consensus properties of the collision. The method determines, based on the consensus properties of the collision, which of the different vehicle occupants were driving the multiple vehicles involved in the collision and behavior of those occupants driving the multiple vehicles at the time of, and following, the collision.

Abstract: The high straightness arrow in the present invention is designed to improve the straightness of the archery arrow by adopting new manufacturing technique and method. Chamber and post are made of dissimilar metals and the chamber includes a wall that creates an external housing and defines an internal airspace. Once the post with shaft is positioned through chamber, nuts are tightened securely, forming an assembly, to straighten post. Due to the different coefficients of thermal expansion of chamber and post, when they are heated simultaneously, the chamber expands more than the post, creating a natural tension along post which results in a near perfectly straight shaft. As the assembly cools, the post and chamber return to their original length, yet the shaft retains its straightened form and thus this manufacturing process yields an arrow shaft that is straighter than shafts made of the same materials but with a traditional manufacturing technique.
