One example is a shock gauge system for measuring an external blast to a hull. The shock gauge system includes at least one accelerometer to produce acceleration data in response to the external blast, a mass with an accelerometer affixed to it, a crush block, a linear displacement potentiometer (LDP), a camera, and a processor logic. The LDP device generates displacement data of a mass being pushed into the crush block when reacting to the external blast. The camera captures images of movement of the mass. The processor logic verifies if the acceleration data is valid by correlating the acceleration data to the displacement data, the images, and/or an amount of displacement into the crush block by the mass. When the acceleration data is valid, the acceleration data may be used to create a more blast resistant hull.

A method for determining stability of a vehicle having a load suspended from the vehicle is provided. The method can include obtaining measurements from a plurality of sensors positioned on the vehicle, obtaining a measurement from a vehicle accelerometer operative to determine an inclination of the vehicle, determining a position of the load suspended from the vehicle, determining a slung load of the load suspended from the vehicle, using the determined slung load and the determined position of the load suspended from the vehicle, determining tipping moments acting on the vehicle, determining righting moments acting on the vehicle and determining a tipping stability based on the determined tipping moments and determined righting moments.

Method and apparatus for remote diagnostics of automobiles are disclosed. In one embodiment, a method may include the steps of reading, by a mobile device, a vehicle identification number (VIN) from a vehicle, transmitting, by the mobile device, the VIN to a diagnostic database, receiving, by the mobile device, an indication that an original equipment manufacturer (OEM) diagnostic tool is required for a diagnosis of the vehicle, and selecting the OEM diagnostic tool for the diagnosis of the vehicle in response to the indication that an OEM diagnostic tool is required for the diagnosis of the vehicle.

An Electronic Stability Control (ESC) system for a vehicle is disclosed. An electronic control unit (ECU) is programmed to reduce vehicle lateral skidding by reducing differences between an intended vehicle direction and/or yaw rate and an actual vehicle direction and/or yaw rate by applying modifications to operation of the vehicle brakes and/or throttle. The ESC system receives inputs from wheel speed sensors, a steering wheel position sensor, a yaw rate sensor and a lateral acceleration sensor. The ESC system also receives input that indicates at least a property of the road upon which the vehicle is located, wherein the road upon which the vehicle is located is determined from a positioning system that uses a map database and the property is determined from the map database. The ESC system incorporates the road property information in determining when and/or how to modify operation of the vehicle to reduce vehicle skidding.
