Abstract: A method for optimizing a test sequence to diagnose a failure mode of a device, such as a vehicle, is provided. At least one symptom of a fault of the device is received, and a plurality of taxonomies is generated. The taxonomies include a device component taxonomy, a fault taxonomy, and a diagnostic taxonomy, and each taxonomy has a plurality of nodes. At least one diagnostic test sequence, based on the symptom and the taxonomies, is generated, costs associated with the diagnostic test sequence are determined, and a cost optimal test sequence, based on the costs and the diagnostic test sequence, is generated.

Abstract: To display patient information, a computing device receives a set of diagnostic values for a patient, a processor of the computing device compares the set of diagnostic values with a set of predetermined normal values, and a video image is displayed having a graphical depiction of the diagnostic values in comparison to the related normal values. The related set of normal values is displayed at a predetermined region of the video image and the set of diagnostic values is displayed on the video image in relation to the certain region of the normal values. Varying levels of relative health of the patient are indicated according the placement of an icon relative to areas of the graphical depiction of the diagnostic values. The video image is a plurality of concentric circles with the diagnostic values being displayed relatively closer to a center of the display in response to the diagnostic values being relatively closer to the values of the related normal values.

Abstract: A dynamic diagnostic plan generator arranges diagnostic test procedures related to a vehicle/power tool/patient symptom or operational problem in a sequence based on a probabilistic Failure Mode and Effects Analysis (FMEA). The diagnostic plan generator also tracks a vehicle/power tool/patient state, and provides instructions for test preparation steps and instructions for performing the diagnostic test procedures. The plan generator further generates schematic illustrations of the diagnostic test procedures, and creates a diagnostic data structure containing information related to the diagnostic test procedures. In addition, the diagnostic plan generator sends and receives information regarding actual failure mode occurrences, for example, to and from a central database. Furthermore, the diagnostic plan generator facilitates the creation of failure mode tests by an expert diagnostics author.

Abstract: In a computer-implemented method of optimizing a diagnostic test sequence to diagnose a medical condition of a subject. A group of diagnostic tests related to a symptom is determined from a pool of diagnostic tests. A probabilistic failure mode analysis is conducted to determine the efficacy of each of the diagnostic tests based on historical outcomes of actual diagnostic testing. The comparative utility of each diagnostic tests based on a plurality of factors that can affect problem resolution is analyzed. A weight is assigned to each factor involved in the probabilistic failure mode analysis. The diagnostic tests are ordered based upon at least one of: a probability of the diagnostic test identifying a cause of the failure mode in a minimum amount of time; a probability of the diagnostic test identifying the cause of the failure mode at a minimum cost; and a relative weighting of minimizing time versus minimizing cost.

Abstract: A system and method for alerting interested parties of component failure are provided. The system made up of a diagnostic tool for identifying a failed component, a reporting device for creating alerts, a routing device to ensure interested parties receive the proper alerts, and a memory to store information for associating parties with the alerts. Information is gathered to create an alert used to notify interested parties of instances of component failures. The alerts are routed to parties known to have an interest in the failure of the component. The system and method may provide information that allows for better planning and design of parts, greater availability to ensure a sufficient inventory of parts, more accurate diagnosis of issues, and more effective preventative maintenance.

Abstract: A diagnostic tool and a computer-implemented method for generating testing and diagnosis procedures for vehicle diagnosis include determining if a first procedure remains to be performed, if a first procedure remains to be performed, then determining whether: there is a second procedure dependent on the first procedure, or the first procedure can run in parallel to the second procedure, if there is a second procedure dependent on the first procedure, then performing the first procedure, if the first procedure can run in parallel to the second procedure, then performing the first procedure, and determining if the second procedure remains to be performed.

Abstract: A vehicle state tracker tracks the state of a vehicle during a diagnostic test sequence to eliminate redundant steps between diagnostic procedures. The vehicle state tracker maintains a list of preconditions required for each diagnostic procedure, reads a current vehicle state from a memory register and verifies the current setting of the vehicle state corresponding to a specific precondition. If the precondition is required and the current setting is not valid, the state tracker further formats a test preparation step corresponding to the precondition for display to instruct a vehicle technician to satisfy the precondition. Otherwise, if the precondition is not required and the corresponding setting is valid, the state tracker formats an instruction to reverse the corresponding vehicle condition. The state tracker additionally receives feedback indicating when a precondition has been satisfied or the corresponding vehicle condition has been reversed, and updates the vehicle state in memory.

Abstract: A system and method for determining work procedures through correlated symptoms are provided. The system made up of a diagnostic authoring apparatus for constructing and managing a diagnostic database. Information is stored in the diagnostic database that identifies vehicles that have the tendency to display certain symptoms in correlation with particular problems. These problems in the vehicles generally have a common solution for that type of vehicle. The problem may be common enough to check for a symptom preemptively, possibly before the vehicle owner is aware of it, or even prior to the manifestation of the symptom. The problem may warrant action taken to fix or avoid the problem. The system and method may associate and mark a problem with a preemptive symptom so a vehicle service/repair professional may be presented with the proper way to handle the associated problem for a particular vehicle.

Abstract: A reverse failure analyzer determines a group of diagnostic test procedures related to a particular vehicle component from a pool of diagnostic procedures, and then identifies the specific failure modes of each of the diagnostic test procedures. The reverse failure analyzer further associates the specific failure modes with the respective vehicle component associated with each of the diagnostic test procedures, and the symptoms associated with each of the diagnostic test procedures to the correlated vehicle components and failure modes. In addition, the reverse failure analyzer can cross-reference various vehicle components that can be the root cause of a particular symptom or a vehicle operational problem. Furthermore, the reverse failure analyzer can receive observed symptoms regarding a particular test subject vehicle and correlate the observed symptoms to the vehicle components that can cause the symptoms based on the results of reverse failure analyses.
