Title: Heliostat error detection

Abstract

The present disclosure describes non-intrusive optical (NIO) characterization methods which efficiency measures optical errors (such as mirror surface slope error, mirror canting error, and heliostat tracking error) of a heliostat field. The methods utilize photogrammetry and deflectometry to analyze an image taken of a heliostat to determine optical errors and increase the amount of solar energy delivered by the heliostat to the receiver.

System for detecting operating errors in a variable valve timing engine using pressure sensors

Patent Wiles, Matthew A.; Marriot, Craig D

A method and control module includes a pressure sensor data comparison module that compares measured pressure volume signal segments to ideal pressure volume segments. A valve actuation hardware remedy module performs a hardware remedy in response to comparing the measured pressure volume signal segments to the ideal pressure volume segments when a valve actuation hardware failure is detected.

Detecting and correcting hard errors in a memory array

Patent Kalamatianos, John; John, Johnsy Kanjirapallil; Gelinas, Robert; ...

Hard errors in the memory array can be detected and corrected in real-time using reusable entries in an error status buffer. Data may be rewritten to a portion of a memory array and a register in response to a first error in data read from the portion of the memory array. The rewritten data may then be written from the register to an entry of an error status buffer in response to the rewritten data read from the register differing from the rewritten data read from the portion of the memory array.

Methods and apparatus using commutative error detection values for fault isolation in multiple node computers

Patent Almasi, Gheorghe [Ardsley, NY]; Blumrich, Matthias Augustin [Ridgefield, CT]; Chen, Dong [Croton-On-Hudson, NY]; ...

Methods and apparatus perform fault isolation in multiple node computing systems using commutative error detection values for--example, checksums--to identify and to isolate faulty nodes. When information associated with a reproducible portion of a computer program is injected into a network by a node, a commutative error detection value is calculated. At intervals, node fault detection apparatus associated with the multiple node computer system retrieve commutative error detection values associated with the node and stores them in memory. When the computer program is executed again by the multiple node computer system, new commutative error detection values are created and stored inmore » « less

Error detection and correction utilizing locally stored parity information

Patent Nair, Prashant Jayaprakash; Roberts, David A.

A processing system includes a memory coupled to a processor. The memory stores data blocks, with each data block having a separate associated checksum value stored along with the data block in the memory. The processor has a storage location that stores parity information for the data blocks, with the parity information having a plurality of parity blocks. Each parity block represents a parity of a corresponding set of data blocks. The parity blocks can be accessed for use in error detection and correction schemes used by the processing system.

System and methods for hardware-software cooperative pipeline error detection

Patent Sullivan, Michael; Hari, Siva; Zimmer, Brian; ...

An error reporting system utilizes a parity checker to receive data results from execution of an original instruction and a parity bit for the data. A decoder receives an error correcting code (ECC) for data resulting from execution of a shadow instruction of the original instruction, and data error correction is initiated on the original instruction result on condition of a mismatch between the parity bit and the original instruction result, and the decoder asserting a correctable error in the original instruction result.
