  • Publication number: 20160172389
    Abstract: A manufacturing method of a thin film transistor includes the following steps. A substrate is provided first. A semiconductor layer is then formed on the substrate. Next, a photoresist pattern including a middle portion and two peripheral portions is formed on the semiconductor layer. The middle portion is disposed between two peripheral portions, and the thickness of the middle portion is greater than each of the peripheral portions. Next, an etching process is performed on the semiconductor layer for forming a patterned semiconductor layer. A photoresist ashing process is then performed to remove at least the peripheral portions of the photoresist pattern to form a channel defining photoresist pattern and expose two portions of the patterned semiconductor layer. Next, the patterned semiconductor layer is treated to form a semiconductor portion and two conductor portions. The channel defining photoresist pattern is then removed.

  • Publication number: 20160171976
    Abstract: A voice wakeup detecting device for an electronic product includes a digital microphone and an application processor. The digital microphone has a function of judging whether a digital voice signal contains a subword according to subword model parameters. If the digital microphone confirms that the digital voice signal contains the subword, the digital microphone generates a first interrupt signal and outputs the digital voice signal. The application processor is enabled in response to the first interrupt signal. The application processor judges whether the digital voice signal contains a keyword according to keyword model parameters. If the application processor confirms that the digital voice signal contains the keyword, the electronic product is waked up from a sleep state to a normal working state under control of the application processor.

  • Publication number: 20160171975
    Abstract: A voice wakeup detecting device for an electronic product includes a front end detecting circuit, a speech recognition processor and a main processor. The front end detecting circuit judges whether a voice signal contains a sub-keyword according to sub-keyword model parameters. If the front end detecting circuit confirms that the voice signal contains the sub-keyword, then it generates a first interrupt signal. In response to the first interrupt signal, the speech recognition processor is enabled to judge whether the voice signal contains a keyword according to keyword model parameters. If the speech recognition processor confirms that the voice signal contains the keyword, then it generates a second interrupt signal. In response to the second interrupt signal, the main processor is enabled. Consequently, the electronic produce is waked up from a sleep state to a normal working state.

  • Patent number: 9350616
    Abstract: A software module on a client computer sends a query to a remote computer server operating a cloud service and receives a response, in order to determine latency. The latency is used with the total size of the packets sent and the packet size to determine the bandwidth available over the network connection at that time. Bandwidth available is calculated periodically and stored in a database of the client computer. Comparing a calculated bandwidth with predefined threshold values indicates whether the network status is good for initiating a cloud service with the computer server or poor. Any number of bandwidth available values are used to determine a slope and the slope is used to predict a bandwidth available value at a future time. A bandwidth available moving average is calculated by summing the bandwidth values for the previous days and dividing by the number of days; the moving average is calculated periodically.
