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.

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.

Certain novel formulations of turf additives that act in such a manner as to permit proper amounts of moisture to contact root systems in order to reduce dry spots within highly managed turf areas and / or lawns. It is theorized that the accumulation of humic acid (and other natural byproduct deleterious compounds) at the topsoil surface in most cultivated grassy areas including sandy soils (such as, in particular, golf greens), results in the production of an effective organic waxy coating on the soil components. Such a coating is hydrophobic in nature and thus dries out the soil itself. The inventive formulation thus permits removal of such accumulated humic acid (and other compounds) from the topsoil to the level necessary to provide effective moisture penetration for sustained grass growth therein (hereinafter referred to as "redistributes"). Methods of providing such beneficial removal of humic substances from target sandy soils are also contemplated within this invention, as well as specific test hydrophobic sand formulations.
