Abstract: An injection nozzle that for a first fuel in a first mode and in a second mode ignition fluid for a second fuel is introduced. The injection nozzle includes an injection nozzle body with first and second injection orifices and a displaceable injection nozzle needle in the injection nozzle body. The first injection orifices have smaller injection orifice cross-sections than the second injection orifices and are arranged at a defined distance. In a first displacement direction for closing the orifices the first injection orifices are located in front of the second injection orifices and seen in a second displacement direction of the injection nozzle needle for the opening or unblocking of the orifices, the first injection orifices are located behind the second injection orifices.

Abstract: A method and a transistor device are disclosed. The transistor device includes: a semiconductor body; first regions of a first doping type and second regions of a second doping type in an inner region and an edge region of the semiconductor body; transistor cells in the inner region of the semiconductor body, each transistor cell including a body region and a source region, the transistor cells including a common drain region; and a buffer region arranged between the drain region and the first and second regions. A dopant dose in the first and second regions decreases towards an edge surface of the semiconductor body. A dopant dose in the buffer region decreases towards the edge surface.

Abstract: Methods and systems of authoring audio signal(s) into haptic data file(s) are disclosed. An audio analysis module analyses the audio signal(s) using filterbank(s) or by performing a spectrogram analysis. Transients are detected in the audio signal. If present, the transients are processed to determine a transient score and a transient binary. A database stores device specific information and actuator specific information. A haptic perceptual bandwidth of an electronic computing device having an embedded actuator is determined by using information from the database. A user interface allows modification of time-amplitude values and transient values based on the determined haptic perceptual bandwidth. Authored time amplitude values are aggregated in authored audio descriptor data, which is passed to a transformation module that fits the data into the haptic perceptual bandwidth and implements algorithms to produce transformed audio descriptor data.

Abstract: Disclosed is a method and system of authoring an audio signal to produce an immersive haptic experience. The method and system preprocesses the audio signal in a preprocessor, which is passed to an audio analysis module. The audio analysis module processes the audio signal for a to produce (a) an array of time amplitude values, and (b) an array of spectral centroid values. In another implementation, the audio analysis module transforms the audio signal using Fourier transformation to produce an array of time amplitude frequency values and an array of spectral centroid values. The array of time amplitude values and the array of spectral centroid values are passed to an authoring tool. A user can modify the array of time amplitude values, the array of timer frequency values and the array of spectral centroid values to adjust the audio signal.

Abstract: A computer implemented method and system of transforming an audio signal into a haptic data to fit into a haptic perceptual bandwidth of an electronic device having at least one actuator is disclosed. The method and system receives the audio signal; filters the audio signal into one or more frequency bands with each frequency band having a center frequency and time-amplitude values; authors the one or more frequency bands by modifying the time-amplitude values by changing, appending or deleting one or more time amplitude values to create an authored audio descriptor data; calculates an available bandwidth and the haptic perceptual bandwidth of the electronic device having at least one embedded actuator and fits the authored audio descriptor data into the haptic perceptual bandwidth of the electronic device to create a haptic data file.

Abstract: Systems and methods for generating a haptic output from an audio signal having a continuous stream of sampled digital audio data are provided. A haptic processing system receives the digital audio data, analyses the digital audio data for processing and extracts haptic signals for generating a haptic effect through an actuator. The method includes passing the digital audio signal on through dynamic processor(s), adjusting the dynamic range of the digital audio signal, extracting the signal envelope of the audio data, synthesising low-frequency signals from the extracted signal envelope, and enhancing the low-frequency content using a resonator. The haptic output is generated by mixing the digital audio signal with outputs from the different modules of the haptic processing system. An analytics module monitors, controls and adjusts the processing of the digital audio signal at the noise gate module, the compressor module and the envelope module to enhance the haptic output.
