    摘要： Methods, devices, and non-transitory storage mediums provide a program handoff between user devices. The program handoff permits a user to select a user device with which to resume a playing of the program. The program handoff also permits a user to set a reminder for playing the program. Methods, devices, and non-transitory storage mediums provide for an application layer-based network offloading of programs. A program is buffered based on a network offloading time and the program is played from a buffer during an execution of a network offload. Network offload prediction is used to minimize network offload time and buffering.

    摘要： A method comprises steps for reconstructing in-cylinder pressure data from a vibration signal collected from a vibration sensor mounted on an engine component where it can generate a signal with a high signal-to-noise ratio, and correcting the vibration signal for errors introduced by vibration signal charge decay and sensor sensitivity. The correction factors are determined as a function of estimated motoring pressure and the measured vibration signal itself with each of these being associated with the same engine cycle. Accordingly, the method corrects for charge decay and changes in sensor sensitivity responsive to different engine conditions to allow greater accuracy in the reconstructed in-cylinder pressure data. An apparatus is also disclosed for practicing the disclosed method, comprising a vibration sensor, a data acquisition unit for receiving the vibration signal, a computer processing unit for processing the acquired signal and a controller for controlling the engine operation based on the reconstructed in-cylinder pressure.

    摘要： The method comprises operating an engine and collecting a real-time accelerometer signal from an accelerometer sensor. The real-time accelerometer signal is digitized and filtered to isolate data in a frequency range associated with combustion to produce a filtered signal data set. The filtered signal data set is integrated to produce an integrated signal data set, and misfire is detected by comparing the integrated signal data set with a predetermined reference data set associated with the same operating point. The apparatus is a control system for an engine that comprises an accelerometer sensor mounted to the engine; a look-up table in which is stored predetermined reference data sets, in association with predetermined operating conditions; and an electronic controller programmed to carry out the foregoing method.

    摘要： The method comprises operating a calibration engine, and collecting combustion characteristic data and reference accelerometer signals, which are correlated with each other and stored in a calibration table. The calibration table can be used by an engine to determine a real-time normal combustion characteristic when the engine is operating by collecting a real-time accelerometer sensor signal and cross correlating with the correlated data stored in the calibration table. Accordingly, the apparatus comprises a calibration engine comprising a calibration sensor, a reference accelerometer sensor and a data storage device for storing the collected calibration data that is correlated with the collected reference accelerometer signals, and an engine equipped with an accelerometer sensor, a calibration table and an electronic engine controller programmed to receive real-time accelerometer signals and cross correlate them with reference accelerometer signals to determine a real-time normal combustion characteristic.
