Abstract: Techniques are described for measuring acceleration of a vehicle with a mobile device. The techniques are applied to detect excessive acceleration events of the vehicle. The techniques are implemented in a mobile device that includes an accelerometer, a global positioning system (GPS) sensor, and a processor configured to identify an excessive acceleration event of a vehicle that the mobile device is located in. The processor is configured to receive, from the accelerometer, a first acceleration data when the vehicle is a rest and a second acceleration data when the vehicle is moving. The processor is also configured to determine, based on the first acceleration data, a gravity vector, and determine, based on the second acceleration data, an acceleration vector for the mobile device.

Abstract: A computer system including a single, fully-integrated software program that allows an employer to assess employee performance for various jobs. The system includes a user interface having graphical inputs that allow a user to rate the quantitative and qualitative skills specific to a job. The system also allows the weighting of the quantitative and qualitative criteria based on job type and graphing such data against the market rate of such employee to determine the value of the employee to the organization. The system is available over a network and allows a user to compare the performance of one or multiple employees over a single period of time or over a longer period of time to track trends in employee performance.
