Abstract: A method includes: obtaining impact values for characteristic conditions; selecting training data subsets respectively from training data sets according to the impact values; obtaining a candidate model and an evaluation value based on the training data subsets; supplementing the training data subsets according to the impact values; obtaining another candidate model and another evaluation value based on training data subsets thus supplemented; repeating the step of supplementing the training data subset, and the step of obtaining another candidate model and another evaluation value based on the training data subsets thus supplemented; and selecting one of the candidate models as a prediction model based on the evaluation values.

Abstract: An LED illuminating showcase includes a frame unit and a lighting unit. The frame unit includes bottom and top seat covers, and a transparent tubular shell extending from the bottom seat cover to the top seat cover and defining a display space with the seat covers. The lighting unit includes opposite terminal subunits respectively disposed in the seat covers, a connecting bar connected fixedly to an inner surface of the tubular shell, having two ends that abut respectively against the seat covers, and that are connected respectively and electrically to the terminal subunits, and an LED module embedded in the top seat cover for illuminating the display space.

Abstract: A signal enhancing method for capacitive touch panel of mobile device provides a reference potential by a reference bar that is next to a sensor bar, wherein when the reference potential is a ground potential, the reference bar becomes a ground (GND) bar. The sensor bar and GND bar may comprise a plurality of tiny sensor bars and a plurality of tiny GND bars, respectively; and may further comprise fishbone sensor bars and fishbone GND bars. The plurality of tiny sensor bars and plurality of tiny GND bars are arranged in an alternative disposition. In this way, when a touch panel is touched, a tiny sensor bar and adjacent tiny GND bar are both touched so as to obtain a large coupling capacitance.

Abstract: A method for unlocking a touchscreen device comprises no involvement of pressing a physical button of the touchscreen device. Rather, it employs a pre-defined touchscreen area as the unlocking spot. The location and size of this unlocking spot can be redefined by a user. When this spot is touched by a finger, a counter will start to count numbers. When it passes a pre-defined number threshold, the activation signal will be sent to a micro control unit (MCU) to activate the MCU. In this way, the touchscreen device is unlocked. In addition, a power saving circuit is provided to execute such unlocking function and reduce power consumption.
