Disclosed are embodiments of a built-in self-test (BIST) architecture that incorporates a standalone controller that operates at a lower frequency to remotely perform test functions common to a plurality of embedded memory arrays. The architecture also incorporates command multipliers that are associated with the embedded memory arrays and that selectively operate in one of two different modes: a normal mode or a bypass mode. In the normal mode, instructions from the controller are multiplied so that memory array-specific test functions can be performed locally at the higher operating frequency of each specific memory array. Whereas, in the bypass mode, multiplication of the instructions is suspended so that memory array-specific test functions can be performed locally at the lower operating frequency of the controller. The ability to vary the frequency at which test functions are performed locally, allows for more test pattern flexibility.

A vehicle diagnostic data collector/analyzer compiles historical vehicle diagnostic data, including measured operating parameters from a number of different vehicles operating under a variety of normal vehicle operating conditions and vehicle component failure conditions, and performs statistical analyses on various vehicle type/operating condition combinations to establish operating parameter ranges corresponding to normal operating conditions and various failure conditions. The diagnostic data collector/analyzer also measures real-time operating parameters on specific test-subject vehicles and evaluates similarities and differences between the measured operating parameters and the established ranges, and correlates the test data with known operating conditions in order to diagnose potential failure modes of vehicle components.

A system, apparatus, and method is directed to dynamically generating content on the fly based on at least one characteristic of a computing device requesting the content, including a characteristic of a network connection. The invention may receive information from a variety of sources, including a manufacturer of the computing device, a header sent by the computing device, and specific test results performed on computing devices similar to the requesting computing device. The information may include screen size, screen resolution, memory size, browser capabilities, applications supported, and so forth. The network connection information may include bandwidth, delays, degradation, connection type, and so forth. The information may be combined to determine an overall device profile. When a request for content is made, the server may employ the device profile to dynamically format the content and provide it optimized for the computing device.

A generic testing framework to automatically allocate, install and verify a given version of a system under test, to exercise the system against a series of tests in a “hands-off” objective manner, and then to export information about the tests to one or more developer repositories (such as a query-able database, an email list, a developer web server, a source code version control system, a defect tracking system, or the like). The framework does not “care” or concern itself with the particular implementation language of the test as long as the test can issue directives via a command line or configuration file. During the automated testing of a given test suite having multiple tests, and after a particular test is run, the framework preferably generates an “image” of the system under test and makes that information available to developers, even while additional tests in the suite are being carried out. In this manner, the framework preserves the system “state” to facilitate concurrent or after-the-fact debugging. The framework also will re-install and verify a given version of the system between tests, which may be necessary in the event a given test is destructive or otherwise places the system in an unacceptable condition.

A self light emitting device having a function of correcting drops in brightness in self light emitting elements in a pixel portion, and capable of displaying a uniform image without brightness irregularities, is provided. A specific test pattern is displayed when an electric power source is connected, brightnesses are detected by photoelectric conversion elements arranged in each pixel, and then stored in a memory circuit. A correction circuit then corrects a first image signal based on portions which are insufficient from standard brightnesses (brightnesses of normal self light emitting elements at the same gray stale, stored in advance), and a second image signal is obtained. Display of an image in a display device is performed in accordance with the second image signal.

A system for testing a cable network during normal operation interleaves test signals with live data traffic. Installed cable modems are used to generate the test signals. During live communication, such modems send upstream data at allotted time periods. Periodically, there are time slots when no modem is transmitting on the network. During these times, specific modems may be directed to transmit specific test signals. A controller such as a cable modem termination system directs specific modems to transmit signals at defined frequencies and powers during specific time slots. In this manner, the system can monitor the frequency response of the cable network at various locations, and thereby determine “on-the-fly” when maintenance or modification is required.

The present invention applies genetic algorithmic generation of test cases the simulation of VLSI logic circuit blocks. The present invention generates a number of original test cases. This aggregate of solutions is provided to a circuit simulator. The results of the simulator are maintained in a matrix or table. The results detail the number of times that particular logic states or events associated with the VLSI block have been stimulated by particular test cases. The aggregate of solutions and the simulation results are then analyzed by the genetic algorithm. The genetic algorithm preferably identifies states associated with the circuit simulation that have not been produced by the original test cases. The genetic algorithm then combines characteristics of various test cases to generate new test cases. The new test cases are provided to the circuit simulator thereby providing a higher degree of confidence that the entire VLSI chip design has been simulated.

Functional testing of an embedded system is performed by a test control system that implements a peripheral emulation module to interface with an externally accessible port of the embedded system. The test control system implements a test generation processor that operates to autonomously resolve abstracted component templates and embedded system description data, specific to the embedded system, to produce a corresponding specific test program. The test control system executes the test program to drive operation of the embedded processor unit to cause transfer of test data through the external interface, which is then autonomously compared to reference data derived through the execution of the test program and specific to the embedded system, whereby the comparison results reflect the correct operation of the embedded system.

The developed automatic test data generation system can automatically transform the test data into a test script required for a specific test platform, and running of the test script can drive the test for running to realize automatic testing for the embedded software.

A general rule-based technique is provided for generating a test case from an abstract internal test case representation. The abstract internal test case representation is based on a test case representation model that includes application states (state information), external interaction sequences (control flow information) and input data. The abstract representation in essence provides a platform independent representation of test cases. An application object model provides the representational capabilities required for capturing structural and behavioral properties of the application under test. Rules can be specified to define which application states (state information), external interaction sequences (control information) and input data sets should be used in the generation of the test case. Multiple data sets can be created and applied to support data-driven test case generation. A technique based on platform mapping is provided to convert a test case into an automation test script for any specific test script execution environment for any specific application platform.

A system and method for testing a radio network. A user at a central site may choose specific radios to be tested and specific test parameters for each one. The user may specify start and stop times, sample rates, whether one or multiple links are to be simultaneously tested, whether results should be presented as snap shots, statistical tables/graphs/charts, or as correlated data from multiple links. Distributed testing is permitted, in which the operational characteristics of one radio are varied, and another radio is monitored for a corresponding change. Once data has been gathered from one or more tests on one or more links, the data may be returned to the central site for analysis and presentation to the user in the selected format.

A driving method is used for driving a liquid crystal display in a dynamic inversion manner. First, a polarity frame is divided into a plurality of polarity blocks with the same area along scanning lines. By a DC balance requirement as the prerequisite, the polarities of one half of the pixels, total n, connected to the same signal line of one polarity block, are positive, and the polarities of other half of the pixels are negative. Polarity patterns, total 2n frames, are generated from sequentially shifting one polarity line to the next polarity line and shifting the bottom polarity line to the top polarity line in each polarity block. Polarity patterns are arranged in a polarity inversion group in a sequence. During a period of the polarity inversion group, each of the polarity patterns separately appears one time for inverting the polarities of the pixels to avoid a flicker image under the displaying of a specific test pattern.
