  • Patent number: 9494232
    Abstract: A method for monitoring a transmission range selector connected to a transmission of a powertrain system is described. The transmission range selector indicates one of a plurality of ranges including Park, Reverse, Neutral, and Drive. The method includes, upon detecting a change in a target transmission range, monitoring whether a signal output from an on-board sensor indicates an achieved range position of the transmission. When the signal output from the on-board sensor does not indicate that the target transmission range has been achieved, monitoring a transmission incorrect direction metric, monitoring a transmission unintended propulsion metric, and monitoring a metric associated with achieving the target transmission range. A fault is detected when any one of the transmission incorrect direction metric, the transmission unintended propulsion metric and the target range achievement elapsed time metric is exceeded.

  • Patent number: 9497729
    Abstract: A method and system for selectively providing cellular offload services to mobile user data devices via vehicle-based access points. Subscribers and affiliates of vehicle-related online services register their user data devices for authorized connections. Vehicle metrics are used to determine the state of a vehicle (being driven or parked), and the metrics of the user device can be compared with the vehicle metrics to determine if the user device is inside the vehicle. Limiting access to authorized user devices reduces load on the vehicular access points and allows preventing the vehicular access points from being erroneously included on access point maps and thereby infecting the maps.

  • Patent number: 9494090
    Abstract: A system according to the principles of the present disclosure includes a misfire detection module and a fuel control module. The misfire detection module detects misfire in a cylinder of an engine. The fuel control module controls a first fuel system to deliver a first fuel to the cylinder and controls a second fuel system to deliver a second fuel to the cylinder. The first fuel and the second fuel are different types of fuel. The fuel control module selectively switches from delivering the first fuel to the cylinder to delivering the second fuel to the cylinder when misfire is detected in the cylinder.

  • Patent number: 9494189
    Abstract: A turbocharger for an internal combustion engine includes a bearing housing and a bearing bore defined by the bearing housing. The bearing bore has an annular bearing groove configured to receive a fluid. A journal bearing is disposed within the bore such that the annular bearing groove encircles the journal bearing and feeds the fluid thereto. The turbocharger also includes a rotating assembly having a shaft with a turbine wheel and a compressor wheel. The shaft has a longitudinal axis and is supported by the journal bearing for rotation within the bore about the axis. The annular bearing groove is characterized by a trapezoidal shape in a cross-sectional view of the bearing bore taken along and through the longitudinal axis. The trapezoidal shape is configured to generate Taylor vortices in the fluid for capturing debris carried by the fluid and keeping the debris from being fed to the journal bearing.

  • Patent number: 9488078
    Abstract: A startup/shutdown control module selectively generates an engine startup command when an engine of the vehicle is off. A starter control module applies power to a starter motor when the engine startup command is generated. A valve control module, in response to the generation of the engine startup command: operates intake valves of cylinders of the engine in a low lift mode when an engine temperature is less than a predetermined temperature; and operates the intake valves of the cylinders of the engine in a high lift mode when the engine temperature is greater than the predetermined temperature.

  • Patent number: 9489620
    Abstract: A computer-implemented system and method of rapidly predicting at least one of residual stress and distortion of a quenched aluminum casting. Input data corresponding to at least one of topological features, geometrical features and quenching process parameters associated with the casting is operated upon by the computer that is configured as a neural network to determine output data corresponding to at least one of the residual stress and distortion based on the input data. The neural network is trained to determine the validity of at least one of the input data and output data and to retrain the network when an error threshold is exceeded. Thereby, residual stresses and distortion in the quenched aluminum castings can be predicted using the embodiments in a tiny fraction of the time required by conventional finite-element based approaches.

An electrolyte solution is disposed inside the electrolytic compartment and inside the other electrolytic compartment. The electrolyte solution is also in contact with the cell membrane. A transducer, which is directly attached to any of the negative electrode or the positive electrode, is capable of selectively transmitting vibrational energy to the negative electrode and/or the positive electrode. The vibrational energy selectively transmitted to the negative electrode and/or the positive electrode causes bubbles to form and to separate i) hydrogen gas bubbles from a surface of the negative electrode, ii) oxygen gas bubbles from a surface of the positive electrode, or iii) both i and ii.
