Abstract: A method calculates temperatures in an electric drive unit. A first temperature detection region has a first temperature and a second temperature detection region has a second temperature. The first temperature is influenced by a first coupling value which is non-linearly dependent on the first temperature and the temperature at the first and second temperature detection regions. The calculations are divided among separate calculation units such that the temperatures can be estimated in real time.

Abstract: In an embodiment, a method includes: receiving, within a processing chamber, a wafer with a photoresist mask above a metal layer, wherein the processing chamber is connected to a gas source; applying an etchant configured to etch the metal layer in accordance with the photoresist mask within the processing chamber; and applying gas from the gas source to perform plasma ashing in the processing chamber.

Abstract: The present invention provides a multimedia broadcasting apparatus. The multimedia broadcasting apparatus includes one plug-compatible base for providing inserting different specification memory cards and utilizes an interface switching circuitry to switch and connect the interface for a compression and decompression circuitry to compress the written in data and decompress the read out data. The compression and decompression circuitry is connecting with a memory, a signal converting control circuitry, and a multimedia drive circuitry for using the memory storing the data. Then, a signal converting control circuitry is to convert the decompressed read out data from a digital signal into an analog signal and to output a drive order into the multimedia drive circuitry connecting to drive a image display device and a audio broadcast device to output the analog signal. Furthermore, a power supply device is provided for providing the required power for the action of all member mentioned above.
