Abstract: The capability to print to a portable document format (PDF) file is provided in a virtualized computing environment that supports a virtual desktop infrastructure (VDI). Printing-related properties, of local printers coupled to a client device, are provided to a host, so that virtual printers at the host can be configured with the printing-related properties. A simulator may be provided at the host to receive the printing-related properties from the client device and to receive a query from a virtualized computing instance for the printing-related properties, instead of the query being directly sent to the client device.

Abstract: The present application provides a pipeline structural fault diagnosis apparatus and a diagnosis method. The pipeline structural fault diagnosis apparatus includes a signal generating apparatus configured to generate an acoustic wave signal by knocking a pipeline; a signal collecting apparatus configured to collect the acoustic wave signal; a signal storage apparatus configured to store the acoustic wave signal for a signal processing and analyzing apparatus to analyze and determine a fault type, a fault degree, and a fault position. The acoustic wave signal after being generated by the signal generating apparatus is collected by the signal collecting apparatus and stored in the signal storage apparatus. The signal processing and analyzing apparatus extracts the acoustic wave signal in the signal storage apparatus, and performs processing and analysis to determine the fault type, the fault degree, and the fault position of the pipeline structure.

Abstract: A method is provided for identifying an equalization target for a channel. The method includes measuring a goodness metric for first and second candidate equalization targets and selecting the candidate equalization target with the best measure of the goodness metric as the equalization target for the channel.

Abstract: A method and disc drive in which tracks and data rates are designated is provided. Under the invention, the write width of a transducer head is determined. A tracks per inch value is adjusted based on the write width, and a data transfer rate is adjusted based on the adjusted tracks per inch value. In particular, the data transfer rate is adjusted such that the adjusted tracks per inch value and the adjusted data transfer rate provide a capacity for the head that is equal to a nominal capacity.

Abstract: Systems and methods are provided through which one or more optimal operating parameters of an electronic device are determined by measuring the objective function of a combinatorial optimization algorithm, such as simulated annealing. For example, the operating parameters are stored in registers in the electronic device. The combinatorial optimization algorithm generates a value of each of the operating parameters of the electronic device. The objective function is measured by operating the electronic device using the value of the operating parameter, and recording at least one operating characteristic of the electronic device. Another value of the operating parameter is generated using the recorded operating characteristic. The process is repeated until an output of the combinatorial optimization algorithm indicates that for each operating parameter, the optimal value is determined.
