TLDR
In this paper, a method of at least partially compensating for errors in ink dot placement by at least one of a plurality of nozzles due to erroneous rotational displacement of a printhead module relative to a carrier was proposed.Abstract:
A method of at least partially compensating for errors in ink dot placement by at least one of a plurality of nozzles due to erroneous rotational displacement of a printhead module relative to a carrier, the nozzles being disposed on the printhead module, the method comprising the steps of: (a) determining the rotational displacement; (b) determining at least one correction factor that at least partially compensates for the ink dot displacement; and (c) using the correction factor to alter the output of the ink dots to at least partially compensate for the rotational displacement.read more

System and method for validating program execution at run-time
TL;DR: In this article, a pipelined processor comprising a cache memory system, fetching instructions for execution from a portion of said cache memory systems, an instruction commencing processing before a digital signature of the cache line that contained the instruction is verified against a reference signature of cache line, the verification being done at the point of decoding, dispatching, or committing execution of the instruction, the reference signature being stored in an encrypted form in the processor's memory, and the key for decrypting the said reference signature was stored in a secure storage location.

Continuous run-time validation of program execution: a practical approach
TL;DR: The Run-time Execution Validator (REV) as discussed by the authors uses a signature cache integrated into the processor pipeline to perform live validation of executions, at basic block boundaries, and ensures that changes to the program state are not made by the instructions within a basic block until the control flow path into the basic block and the instructions in the Basic block are both validated.

Method and apparatus for detecting disparity
TL;DR: In this article, the disparity between corresponding pixel positions in a first and second image capturing the same scene was detected using an apparatus consisting of a determiner, a comparator, and an obtainer to obtain the disparity in accordance with the determined similarity of the pixels.

Method of Storing Secret Information in Distributed Device
TL;DR: In this article, a method of storing a function result of a secret key in memory of a device for distribution is presented, which involves applying a first, one way function to a random number stored in the memory of the device, thereby generating a first result, applying a second function to the first result and the secret key, and storing the second result, and then distributing the device with the random number and second result stored in memory and the key not stored in a memory.

Misregistration correction for bidirectional printing in consideration of inclination of nozzle array
TL;DR: In this paper, a correction value is used to correct misalignment of recording positions in a main scanning direction using a representative nozzle sub-array as a reference, which is within a predetermined range around the center of a nozzle array provided on a print head.

Alignment system and method of compensating for skewed printing in an ink jet printer
TL;DR: In this article, a method of printing with an ink jet printer compensates for skewed printing on a print medium is described, where the ink is jetted onto the print medium from the ink emitting orifices during the first and second scans at selected ink dot placement locations generally corresponding to one of the columns of pixel locations.

Method and system for compensating for skew in an ink jet printer
TL;DR: In this paper, a method and system for compensating for swath skew with respect to a perpendicular direction of carrier travel is proposed, which can be carried out through software and/or hardware and eliminates the need for mechanical adjustment of an ink jet printer.
