    摘要: Disclosed herein are methods for detecting a water leak in a locomotive engine cooling system comprising numerous components, each being a potential source of leakage of water. The method typically comprises performing at least one inspection providing an indication of a water leak from an engine cooling system of the locomotive. The step of performing at least one inspection may comprise at least one of several steps including performing a visual inspection to determine if water is leaking from a portion of the cooling system external to the engine; performing a visual inspection of exhaust of the engine to detect an indication of water vapor in the exhaust; performing a visual inspection to detect an indication of water leaking into an intake air manifold 30 of the engine; performing an engine oil analysis to detect water in the engine lubricant; reviewing a fault log history for the locomotive; and checking a level of a cooling system sight glass. The method allows for the isolation of potential sources of the water leak from one another so as to prevent false positive leak identification caused by transient water flow between the potential sources. If an engine cylinder assembly is a component identified as a potential source of the water leak during the water pressurization test, the method enables further testing to confirm leakage at such cylinder assembly, before undertaking the costly and time-consuming process of removing the cylinder assembly from the engine. Cylinder assemblies can be tested for leaks by performing an air leak test disclosed herein.

    摘要: A client/server networking topology comprising a trusted server agent (TSA) (e.g., software application) that runs either at a client node or at a node in close proximity to the client and provides various trusted services to the client on behalf of a trusted server. In instances where the node in which the TSA software runs (i.e., the client or a node in close proximity) may be untrusted, and/or unreliable, methods are provided for making the TSA software running on the untrusted and/or unreliable node provide trusted and reliable services. In one aspect of the invention, a method for providing trusted service in a client/server system comprises the steps of: providing at least one client; providing at least one trusted server (TS); providing at least one trusted server agent (TSA) which is executing on or near the at least one client; providing a trusted service by the at least one TSA to the at least one client on behalf of the at least one TS.

    摘要: Each match word line driver circuit associated with a content addressable memory (CAM) utilizes a scannable latch for testing. The scannable latches associated with a particular CAM are connected together, scan output of one to scan input of the next, forming a scanning latch chain. In test mode the scannable dynamic latch is used either for testing CAM match circuits or for driving word lines to test the RAM array. Testing CAM match circuits is accomplished by patterning the CAM array with known storage values. The match circuitry then compares an effective address to each storage value and the results are scanned out. Testing the RAM array is performed by driving each word line with a known scan value. Each word line responds the scan value and a sense amplifier outputs a RAM array value based on the word line.

    摘要: A dynamic sense amplifier (10) cooperates with an embedded latch arrangement for converting signals read from a memory cell array to digital signals. The dynamic sense amplifier (10) is connected to a complementary pair of data output lines, each associated with a data output node, and to a complementary pair of data lines from a column decoder associated with the memory cell array. The dynamic sense amplifier (10) is also connected to a sense enable line for receiving a sense enable signal, while the latch incorporated in the dynamic sense amplifier (10) is connected to a latch enable line. The dynamic sense amplifier (10) operates to quickly develop an intermediate charge state at the data output nodes in response to a read charge state on the data lines and a sense enable signal applied at the sense enable line. After developing the intermediate charge state, the latch enable signal is applied to the latch enable line to take the intermediate charge state to a final charge state at the data output nodes. This final charge state at the data output nodes produces data signals on the data output lines. The latch also operates in response to the latch enable signal to hold the charge at the data output nodes, thereby holding the data at the data output lines.
