摘要:
An automation controller for next generation testing system includes a database including a plurality of scripts and modules, a business layer component, and an automation component. The automation component includes an automation agent and an automation worker. The business layer component is operable to determine a next script from the plurality of scripts and modules and send the next script to the automation component in response to a get next script request sent by the automation component. The automation agent is operable to send the get next script request to the business layer, receive the next script from the business layer, and send the next script to the automation worker for execution. The automation worker is operable to execute the next script or section thereof, obtain a result, send status updates, send proof of life notifications and the result of execution to the automation agent.
摘要:
A method of supplying test data for test scripts is provided in an integrated testing platform, where the testing platform includes a prioritization and assignment manager configured forward test scripts to a selected testing individual. Each test script is mapped to an input data set if a corresponding input data set is available. Requests for test scripts made to the prioritization and assignment manager are monitored, and if the test script to be supplied in response to the request has a corresponding mapped input data set, the corresponding input data set is retrieved from a database, and the input data set is provided to the test script prior to execution of the test script.
摘要:
An insert to limit the rate of flow of liquid from a drinking cup, the insert comprising mounting means to locate the insert within a cup above a liquid contained therein but below a brim of said cup so that a peripheral edge of the insert is spaced a predetermined distance from an inner surface of a cup such that, when a person drinks from the brim of a cup fitted with the insert, the rate of flow of liquid to the brim is limited by the insert.

A window regulator, e.g., for a vehicle window, which includes opposing block and pulley arrangements that interact via a lift pulley mounted to a lift plate that slides along a rail. Operative movement of a crank assembly in a first sense tensions a cable to move the lift plate towards a first end of the rail and operative movement of the crank assembly in a second sense, opposite the first sense, tensions a cable to move the lift plate towards a second end of the rail. The regulator enables the reduction of the operating torque requirements without affecting the packaging of the crank assembly.

摘要:
A stab joint coupling, for joining corrugated pipes, has a male connector and a female connector both having means for attachment to a first and second piece of pipe by engaging the corrugation of the pipe. A circumferential elastomeric sealing means is positioned between the joined coupling connectors to effect a substantial liquid seal for the joint. The coupling permits two pieces of corrugated pipe to be joined relatively inexpensively and quickly by workers in the field.
摘要:
The subject invention provides a rock catchment barrier comprising a plurality of modules. Each module comprises a concrete base having a top surface, a post, a concrete barrier, an aperture for connecting the post to the top surface of the concrete base, a connector for connecting the concrete barrier to either side of the concrete base, and a fence panel for catching rocks, the fence panel being attachable to the post, wherein when the concrete base is connected to the concrete barrier, and the post is connected to the concrete base and the fence panel for catching rocks, a resulting module is formed. The rock catchment barrier provides protection for use in a rock excavation or scaling site where there is a need to stop rocks which are projected away from the site, such as when the rock excavation or scaling site is adjacent to a flow to traffic.
