Abstract: The invention relates to a device of generating simulation signals for Controller Area Network (CAN). The device in this invention simulates CAN data streams normally generated by electronic control units (ECUs) in automobiles, vehicles, boats, etc. without the presence of these ECUs. The device in this invention has a visual display of simulated signals' values. In addition, this invention reveals a remote terminal method and software. The remote terminal software in this invention can control the simulated signal via graphic user interfaces. The remote terminal software in this invention also displays the precise values of simulated signals via graphic user interfaces. Furthermore, this invention presents an advantageous method using a license identification management technique to change the functionality and features of the simulation device without any hardware modifications and without sending the device back to the device manufacturer.

Abstract: A method comprising two steps is provided for a simplified on-site bootloading process. Step 1: having a computer or similar device preload initialization instructions and executable codes to an intermediate device. Step 2: having that said device transfer such initialization instructions and executable codes to the operating device. The intermediate device named “bootloader-to-go” is provided in this invention. The said bootloader-to-go device provides the uncomplicated transferring of the initialization instructions and executable codes to the operating device without complex configuration steps. The said bootloader-to-go device is handheld, operated by a single operating switch and is equipped with versatile I/O bus connections compatible to operating devices with various I/O types. There is no need of a hosting computer or similar device on site, the bootloading speed is not controlled by a hosting computer, and therefore the bootloading time is predictable and can be repeated.
