摘要： A method and system for using Equivalent Time Sampling to improve the effective sampling rate of sensor data, and using the improved-resolution data for diagnosis and control. Data samples from existing sensors are provided, where the sampling rate of the existing sensors is not sufficient to accurately characterize the parameters being measured. High-resolution data sets are reconstructed using Equivalent Time Sampling. High-resolution input data sets are used in a system model to simulate the performance of the system being measured. Results from the system model, and high-resolution output data sets from Equivalent Time Sampling, are provided to an estimator, which provides accurate estimation of measured quantities and estimation of quantities not measured. Output from the estimator is used for fault diagnosis and control of the system being measured.

摘要： A method is provided for enhancing service diagnostics utilizing service repair data of previously serviced vehicles. Service repair data of previously serviced vehicles is obtained from a memory storage device. The service data is compiled into a service diagnostic code dataset and a service labor code dataset. The service diagnostic code dataset and service labor code dataset are categorized into an electronic data table. Respective combinations are formed in the electronic data table. An aggregate count is determined for each respective combination in the electronic data table. Either of a respective diagnostic code or a respective service labor code is identified having a correlation with more than one of either service diagnostic codes or service labor codes. At least one of a service repair procedure used to repair the vehicle or a respective service diagnostic code used to identify the fault is modified in response to analyzing the respective combinations.

摘要： A system and method for interpreting formal verification results of PLC logic code used to control a manufacturing process, or other automated process, where the interpretation process does not require highly skilled technicians having significant experience in computer and mathematical algorithms. The verification process includes providing a verification results summary to check the compliance of the code with respect to the specifications. The verification results summary is analyzed and categorized to determine whether violations or errors are found in the results. The results can be depicted by assertion trees if a direct assertion between the PLC logic and the specifications can be provided. Alternatively, the results can be depicted by a reduced ladder logic if a direct assertion between the PLC logic and the specifications cannot be provided and a simulation is required. The specification refinement suggestions will be provided if the critical variable for violations is identified.
