G06F 17/10

US Classification:

235375, 23546207, 235385, 23546225

Abstract:

A method and system for collecting, storing, and processing automatic identification code information includes receiving automatic identification code information and parsing it based on stored definitions for automatic identification codes and/or automatic identification code standards. Various data configurations may be used to store definitions and to facilitate parsing of raw automatic identification code data. For example, a first component may be used for generally defining one or more automatic identification code standards and a second component may be used for detailed information regarding code definitions, such as information relating to code segments. In addition, the system may facilitate further processing of parsed automatic identification code information, such as for cycle counting or parts movement of inventory.

International Classification:

G06F 19/00

US Classification:

702 72

Abstract:

A phase-locked loop is characterized by analyzing phase noise in its output signal while known levels of input phase noise are provided. The resulting data provides intrinsic phase noise and gain of the phase-locked loop. These values provide a general relationship between input phase noise and output phase noise for the phase-locked loop, which allows estimation of output phase noise corresponding to a given level of input phase noise, and allows estimation of input phase noise corresponding to a given level of output phase noise.

US Classification:

702 66, 702 67, 702 69

Abstract:

A method for predicting a predetermined bit error rate for an actual data transmission from a transmitter to a target receiver over an actual backplane link is disclosed. The method involves defining a simulated backplane corresponding to an actual backplane link intended to be used for data transmission between a transmitter and a target receiver. Once the simulated backplane is defined, a data transmission from the transmitter to the receiver is simulated and captured across the simulated backplane. A waveform simulation of the data transmission over the simulated backplane is then generated. The waveform simulation takes into account characteristics of the simulated backplane and the target receiver. From the waveform simulation, a total jitter for a predetermined bit error rate for the data transmission is extrapolated.

US Classification:

714704, 714742, 375226

Abstract:

An integrated circuit (“IC”) includes circuitry for use in testing a serial data signal. One such IC includes circuitry for transmitting the serial data signal with optional jitter, optional noise, and/or controllably variable drive strength. One such IC also includes circuitry for receiving the serial data signal and performing a bit error rate (“BER”) analysis in such a signal. Such an IC provides output signals indicative of results of its operations. One such IC operates in various modes to perform or at least emulate functions of an oscilloscope, a bit error rate tester, etc. , for testing signals and circuitry with respect to jitter-tolerance, noise-tolerance, etc.

International Classification:

G06F 100

US Classification:

364900

Abstract:

The invention generally relates to improvements in the process and storage of formatted voice, graphic and image data. A new editing process allows the same commands to be applied to a plurality of data files of varying resolution and formats. The technique employs an edit tracking file to retain the edit commands applied to a file of a first format. The edit commands are then executed against a file of a second format to perform the identical editing steps to the second file. This process avoids the inaccuracies associated with converting information to a common format while providing the benefits of supporting multiple formats of file information.
