Abstract: A method to secure boot an electronic device is disclosed according to some embodiments. The method includes receiving a request to initiate a boot sequence using memory content stored in a non-volatile memory circuit. A secure boot circuit receives verification data from the non-volatile memory circuit indicating the memory content. The verification data includes an error correction code for the memory content without including all of the memory content. A cryptographic hashing operation is performed to the error correction code in the secure boot circuit to obtain a digest of the error correction code. The digest is compared with a pre-stored reference digest to generate a verification signal. The verification signal is provided to the electronic device indicating whether the boot sequence passes the verification.

Abstract: In an interface, a host device or controller configures a peripheral or remote device to send data back to the host device. The remote device is operatively coupled to one or more sensors located throughout the vehicle and performs an analog to digital conversion on signals received from the sensors. The signal data is automatically transferred into particular locations in memory of the host device. In this manner, the host merely has to access its memory to obtain fresh data needed to control one or more operations of the vehicle.

Abstract: One embodiment of the invention includes a method for managing a system. The method includes providing a plurality of system values and generating an event signal if one of the plurality of system values is logically related to a compare value. At least two of the plurality of system values are captured at a time that is related to the event signal. Other systems and methods are also disclosed.

Abstract: A system that controls the application of a clock signal used to autonomously transfer data from a remote device to a host device. The clock signal can be allowed to continually cycle for legacy applications, or can be controlled to only cycle when data transmissions are occurring.

Abstract: A tire monitoring system and associated method includes a plurality of tire sensor modules configured to transmit tire data in a wireless fashion at a predetermined time interval. The system also includes a vehicle control module that is configured to receive the tire data from the tire sensor modules, and is further configured to dictate the predetermined time interval at which the tire data is transmitted by the tire sensor modules.

Abstract: The present invention advantageously provides a microprocessor controlled power delivery circuit with short circuit protection. The microprocessor controls the load current flow at the circuit's load connection terminal by connecting this terminal to the positive or negative side of a power supply or opening the circuit to prevent current flow. The short circuit protection uses a passive electrical component feedback circuit to communicate the voltage level at the circuit's load connection terminal back to the microprocessor. The microprocessor routinely monitors this voltage and compares this voltage against the expected voltage at this terminal. When the actual voltage does not match the expected voltage, the circuit will provide protection by interrupting current flow through the load connection terminal.
