Disclosed herein are mechanisms and methods for maintaining and/or achieving a target Automotive Safety Integrity Level (ASIL) level for a vehicle. One or more shutters of one or more corresponding image sensors of the vehicle may be repeatedly closed at a predetermined rate. While the shutters are closed, output values of each image sensor may be measured. A soft error rate may be determined for the vehicle based on the measurement of the output values, and one or more system countermeasures sufficient to maintain and/or achieve a target ASIL level based at least on the soft error rate may be implemented.

Image sensor based countermeasures for improving electronic system integrity

One embodiment describes an automation system including a sensor that determines operational parameters of the automation system; one or more actuators that perform control actions during operation of the automation system; and a control system communicatively coupled to the sensor and the one or more actuators. The control system includes memory that stores the operational parameters; determines occurrence of memory errors in data stored in the memory; determines error parameters that indicate characteristics of the memory errors; determines error-corrected data by correcting the memory errors based at least in part on the error parameters; adaptively adjusts a refresh rate used to refresh stored data in the memory based at least in part on the error parameters; and determines control commands instructing the one or more actuators to perform the control actions by processing the error-corrected data.

Memory device error based adaptive refresh rate systems and methods

An example apparatus for error correction can include an array of memory cells and a controller. The controller can be configured to perform a dummy read on a portion of data stored in the array. The dummy read can include sending a portion of data on output buffers to a host. The controller can be configured to error correct the portion of data in the host. The controller can be configured to write the portion of data back to the array.

Error correction to reduce a failure in time rate

Improved integrated circuits, memory devices, circuitry, and data methods are described that facilitate the adjustment and reconstruction of signal timing of devices by providing for an interface having inputs and/or outputs that are adjustably delayed. This allows embodiments of the present invention to sense the signal delay and utilize adjustable input or output delays to correct the signal timing relationships such that correctly timed communication signals are received by the internal circuitry of the device. In one embodiment of the present invention, a register is utilized to adjust the timing delay of individual input and/or output signals for the device. This increases the robustness of the device and its resistance to communication or data corruption, allowing larger ranges of environmental conditions and input capacitances of systems or communication busses to be tolerated.
