Abstract

A reprogramming device is used for reprogramming embedded systems. The reprogramming device comprises a microprocessor, a memory programmed with software to accomplish the reprogramming of distinctly different embedded systems architectures, and one or more hardware devices that facilitate communication over multiple protocols contained in a portable package designed for both one-time and multi-occurrence use scenarios. In some embodiments, the reprogramming device is able to be used to enhance one or more attributes of performance of existing embedded systems through the reconfiguration of internally stored parameters. In some embodiments, the reprogramming device is also to be used to extract and receive information and instruction from existing embedded systems and enable useful presentation of this information. As a result, the reprogramming device is able to be used to adjust and/or monitor the parameters of the on-board diagnostics computer of a vehicle to ensure peak performance and detect errors.

Claims
