  • Patent number: 10288015
    Abstract: The invention relates to a method for checking a functionality of a differential pressure measuring unit (31) in an exhaust gas recirculation system (1) of a motor vehicle, and a corresponding exhaust gas recirculation system (1). In an air intake duct (5), a sensor flap (11) is provided downstream of an air filter (9) and upstream of an opening (37) of an exhaust gas recirculation duct (25). This sensor flap (11) is set in two different positions and a value of a pressure drop in the exhaust gas stream is measured for each position as said gas stream flows through an exhaust gas recirculation stream valve (29) provided in the exhaust gas recirculation duct (25). If the measured pressure drop does not significantly change despite the movement of the sensor flap (11), it can be assumed that there is a fault in the differential pressure measuring unit (31).

  • Publication number: 20190054863
    Abstract: A method for operating a motor vehicle, in which a control device of the motor vehicle receives a control input conducted by a vehicle occupant. By means of a sensor device of the motor vehicle, it is checked whether at least one predetermined criterion is met. When the at least one predetermined criterion is met and when the control input is received, the control device brings about a movement of at least one sun visor of the motor vehicle from a stowed position into a functional position, in which the at least one sun visor is flipped down. Furthermore, the invention relates to a motor vehicle.

    Abstract: Methods, systems, and computer-readable storage media determining a behavior model of a computing system under test. In some implementations, actions include executing, using a user interface of a computing SUT, an initial test script on the SUT; recording, after executing the initial test script, a state of the SUT in the behavior model by observing one or more events that can be triggered using the user interface of the SUT; and iteratively refining the behavior model until an end condition is reached by generating one or more new test scripts, executing the new test scripts on the SUT to test unobserved behavior, and recording one or more new states reached by executing the new test scripts on the SUT in the behavior model.

  • Patent number: 9192416
    Abstract: This invention relates generally to devices, systems and methods for the internal fixation of bone fractures, and particularly, to intramedullary fracture fixation devices such as those used in, for example, the treatment of long bone fractures. An IM rod preferably is provided with multiple curved sections in different planes preferably designed to conform with the long bones of a patient, both during insertion and in the rod's final position in the long bone. In addition, the overlap of portions of the curved sections results in a co-planar curvature of portions of the IM rod which assist in the insertion process by guiding the proper rotation of the IM rod as it is inserted into the bone. Spiraling flutes extending down the distal portion of the rod also assist in properly guiding and orienting the rod about its longitudinal axis during insertion such that the appropriate segment of the curved rod conforms with the appropriate portion of the long bone at the appropriate place.
