Abstract: A vehicle theft prevention system switches an engine from an immobilized state to a mobilized state when an ID code received from a mobile device carried by a user matches an ID code registered in advance, and keeps the engine in the immobilized state when the ID code received from the mobile device does not match the ID code registered in advance. Further, when a disable command is received from the center and it is detected that the vehicle is in an unused state based on a state of a predetermined signal indicative of states of the vehicle, the system immobilizes the engine and prevents the engine from being switched from the established immobilized state to a mobilized state even if the ID code included in the signal received from the mobile device matches the ID code registered in advance by invalidating the ID code of the mobile device.

Abstract: A security method obscures the visibility through an aircraft's windshield upon determining the existence of a potential security problem, such as a terrorist attempting to take unauthorized control of the aircraft. The windshield can be obscured by various means such as actuating a liquid crystal system of a chromogenic glass pane; automatically drawing a shade or curtain in front of, behind, or within the windshield; and applying to or within a windshield an opaque or translucent fluid. Although an obscured windshield would likely impede the terrorist, it would not create a problem for a skilled pilot that is more familiar with the aircraft and its instruments. Determining whether a potential security problem exists can be accomplished in various ways such as scanning ID cards; reading passwords; communicating with the flight crew; actuating emergency buttons aboard the aircraft; and comparing cell phone numbers, voice imprints, or facial images to a database.

Abstract: A vehicle anti-carjacking and theft prevention device incorporating a disabling system for terminating operation of a vehicle whether or not the owner is present thus preventing the theft and/or hijacking of the motor vehicle. The system is passive and always activated when the vehicle is started whether by key or if it is hot-wired.

An LED light will signal operator that normal driving operation has been attained. If the touch sensor is not touched by the operator after starting the engine, in the time allowed by the manufacturer, then the system will cut the operation of the fuel pump thereby disabling the vehicle within the factory specified distance. The vehicle cannot be restarted unless it is reset. Thereby the system has a hidden reset jack/button for normal operation of the vehicle to be regained.
