Abstract: A multi-processor system includes a first processor that includes a first time base counter that outputs a first time base count, a second processor that includes a second time base counter that outputs a second time base count, and a communication bus. The first and second processors exchange the first and second time base counts on the communication bus. The first and second processors determine a skew based upon a difference between the first and second time base counts, and the first and second processors synchronize with each other based upon the skew.

Abstract: Multiple positions within a mechanical system are measured with a plurality of sensors including at least one 4-wire and at least one 5-wire sensor. The 5-wire sensor has two output voltage signals sent to a signal conversion processor, and the 4-wire sensor also sends a signal. A sum is created of the two voltage signals from the 5-wire sensor. An excitation voltage supply supplies a common excitation voltage to both sensors. Feedback of the excitation voltage is measured by the signal conversion processor. The excitation voltage feedback is utilized to ratio-metrically correct a position feedback signal from the 4-wire sensor at the signal conversion processor. The signal conversion processor is able to synthesize a signal indicative of the excitation voltage from the two voltage signals sent from the 5-wire sensor in the event the excitation voltage feedback is not received at the signal conversion processor.

Abstract: A method for controlling a vehicle is provided. The method includes generating a digital control signal, generating a digital simulated signal based on the control signal, the digital simulated signal simulating one of a mechanical or analog input signal, converting the digital simulated signal into an analog signal, and controlling a control device of the vehicle using the analog signal.

Abstract: In one example, a method includes receiving, by a controller device from a master device operably connected to the controller device, a memory access request configured to request access to computer-readable memory of the controller device. The method further includes sampling, by the controller device, time-varying data received from a controlled device operably connected to the controller device, and generating, by the controller device in response to receiving the memory access request, an access key using the sampled time-varying data received from the controlled device. The method further includes transmitting, by the controller device, the generated access key to the master device, and enabling, by the controller device, access to the computer-readable memory of the controller device in response to data write commands received from the master device that include an access code based on the access key.
