Air circulation in a system

Abstract: An example system may include racks that house slots, in which devices may be stored for testing. Cold air from a cold atrium is drawn over the slots and expelled into a warm atrium. The resulting warm air is cooled and then recycled back through the slots to control slot temperature.

Determining electrical path length

Abstract: An example process for determining electrical path lengths includes: injecting current into a transmission line having a known capacitance per unit of length; determining a rate of change in voltage on the transmission line in response to the current; determining a capacitance of the transmission line based on the change in voltage; and determining an electrical path length of the transmission line based on the determined capacitance of the transmission line and the known capacitance per unit of length

Concurrent test planning

Abstract: Testing multiple device functions in parallel can yield significant test time and cost of test reductions. This paper discusses the planning process and algorithms required to realize an efficient and achievable concurrent test plan.

Method for web based software object testing

Abstract: A system for testing middleware of applications in the N-tiered model. The test system contains test code generators, test engines to execute multiple copies of the test code and a data analyzer to analyze and present the results to a human user. The system is able to automatically generate test code to exercise components of the middleware using information about these components that would otherwise be available to the application under test. Multiple copies of the test code are executed in a synchronized fashion. Execution times of multiple events are recorded and then presented in one of several formats. With the system, an application developer can identify components that represent performance bottlenecks or can gather information on deployment properties of individual components that can be used to enhance the performance of the application under test.

Is a Protocol Aware test system feasible

Abstract: A Protocol Aware (PA) test system would greatly assist the test engineer in multiple highly leveraged activities but is such a system in fact possible to build? One must construct the system so that pins can be grouped by membership in the various protocols on the DUT. Once grouped, local processing must be flexible enough to understand each protocol and respond properly to commands with reasonable latency. Since the supply of new protocols is unlimited, it must be possible to add new protocols at any time. And then, when all this is complete, it must be possible to synchronize operation of the various protocols so that a complete test of the DUT results.
