    摘要: An ultrasonic test system for inspection of structural material includes a test electronics for controlling a plurality of ultrasonic transmitter and receiver channels. This test electronics is operated by sequencing the system through the several channels, but the evaluating circuit is common to the receive channels. The duration of the test, timing of launching, timing of beginning receiving response signals, time and duration of looking windows for identifying and timing particular responses, and comparison data, all are operating and acquisition parameters for operating the electronics. These parameters are furnished from external sources and are programmable and exchangeable, e.g., from test to test. At least some of these parameters are updated on the basis of data as acquired during the test.

    摘要: A diagnostic system (10) particularly though not exclusively for use in an engine management system is provided for generating a diagnostic trouble code (DTC) to indicate the operational status of a component or sub-system which is being evaluated by the diagnostic system. The diagnostic system includes a diagnostic function module (DF Module) (20, 20', 20") for each DTC or a group of related DTCs associated with a component or sub-system. The DF module including device (22) for executing an evaluation routine to evaluate the operational status of a component or sub-system to which the DTC of the specific DF module relates, and a diagnostic function scheduler (DF scheduler)(30) for determining which DF module may be allowed to execute an evaluation routine ant a particular time. Each DF module (20, 20', 20") includes device (22) for producing a ranking value dependent on the operating status of the component or sub-system being evaluated, a ranking value being generated each time an evaluation routine is performed; device (23) for processing and storing statistical results of the ranking values obtained over a number of evaluation routines; device (23) for evaluating the statistical results to produce evaluated data in the form of either an evaluated no-fault signal or an evaluated fault signal, and device (24) for transmitting the evaluated signals to the DF scheduler (30).

    摘要: The system includes a plurality of individually selectable transmitter and receiver channels, a common controller and a common acquisition unit constructed to operate on the basis of parameters which are furnished to the controller and the unit as input signals. Some of the parameters are held in a memory and are withdrawn on the basis of test identification numbers to set up the acquisition unit. The acquisition unit has a transit time counter and two parallel operating looking window generators and several comparator stages, operating under utilization of such parameters. The data as acquired by a test, are accumulated and processed to determine new parameters, if necessary, and feeding them to the memory. The controller conducts the tests on the basis of sequencing the system through a group of test identification numbers, and provides also launch delay and receiving delays on the basis of externally, updatable parameters.
