Abstract: System and methods validate a tangible financial instrument, such as a paper check, that comprises printed or embedded thereon a readable security graphic. The readable security graphic is decodable to a public key or token for the tangible financial instrument. Each key/token can correspond to a financial instrument of an account of an account holder. A host server can retrieve a private key associated with the first account identifier. The host server can then compare the public key/token with the private key associated with the first account identifier. Upon a determination that the private key associated with the first account identifier is paired with the public key or token, the host system can generate and issue an approval notification for the tangible financial instrument. Conversely, the host system can issue a warning notification for the first tangible financial instrument if there is no match.

Abstract: Provided are a computer program product, system, and method for applying a code update to a target system from a personal communication device. A code update command is received from a messaging application, executing on the personal communication device of the user, indicating a code update to install on the target system a code update maintained in the target system. The code update command is processed to extract indication of the code update to install and a target system user identifier of the target system on which to install the code update. At least one job is generated to install the code update on the target system. The at least one job is transmitted to the target system to cause the target system to process the at least one job to install the code update.

Abstract: An approach is disclosed that identifies an anomaly in a Volume Table of Contents Index (VTOC Index) that is associated with a Direct Access Storage Device (DASD) Volume Table of Contents (VTOC) that corresponds to a DASD. The approach operates to automatically correct the VTOC Index based on the identified anomaly.

Abstract: A method for safely sharing access to a volume is disclosed. In one embodiment, such a method includes notifying a storage system that a volume on the storage system is in use by a first host system. The method stores, on the storage system, a first indicator indicating the volume is in use by the first host system. When the storage system receives an I/O request from a second host system to access data on the volume, the storage system reads the first indicator to determine that the volume is in use by the first host system. The storage system may then reject the I/O request from the second host system as a result of the first indicator. A corresponding system and computer program product are also disclosed.

Abstract: Method for preparing a purified crystal for use in an optical component, from an impure crystal having impurities or crystal defects capable of causing a specific absorption of incident light, includes heating the impure crystal to a temperature at which ions in the crystal are mobile and provide conductivity. A part of the crystal is illuminated with an electromagnetic purifying beam having a frequency in or near a visible frequency range so as to optically excite and migrate charges in the crystal, the charges being compensated by a counter-migration of the ions so as to be fixed in place thereafter so as to provide a purified crystal zone. The crystal is cooled to a future operating temperature.

Abstract: A method for determining absolute value of a rotational angle includes imaging a segment of a code track onto a sensor such that the sensor generates a corresponding output signal. The track includes a code in the form of a light and dark transition pattern over an angular range. The code contains code words with each code word corresponding to a respective angular value. The code word of the imaged segment is determined from the position of the transitions in the output signal to determine the angular value of the imaged segment. The position of the transitions in the output signal is compared with a reference curve to determine position deviations between the output signal and the reference signal. The reference curve represents the transitions expected in the output signal in the absence of unwanted mechanical influences. The unwanted mechanical influences are determined as a function of the determined deviations.
