Abstract: The systems and methods disclosed herein are configured to unlock a vehicle. The systems use a hash function signature for authentication and use a vibration signal to transfer the hash function from a mobile device to a vehicle.

Abstract: A method of controlling a fuel supply system of an engine 10 of a motor vehicle 50 is disclosed in which an engine driven variable output high pressure fuel pump is operated at a high demand level to charge a high pressure fuel accumulator with fuel during a shutdown of the engine and, during a subsequent start-up of the engine, use fuel from the accumulator while operating the high pressure fuel pump at a low demand level. This reduces the fuel consumption of the engine by using kinetic energy from the slowing engine to drive the high pressure fuel pump and increases the deceleration of the engine.

Abstract: My new mask is like dust masks and surgical masks but it's more efficient and more comfortable. The user can berathe comfortably all day through the cotton cloth I use to make said mask, and it can be reused many times because it's washable. The new built-in padded nose clamp is made of a copper wire that is plyable enough to easily bend to fit the contour of the users nose and strong enough to hold it's shape during normal use. To gather the bottom of said mask snugly under the users chin I built in some draw strings that are fastened together under the users chin with an adjustable quick fastening device. The new design, new materials and the new adjustable devices make my mask easy to use, efficient and comfortable enough to wear all day.
