Abstract: When a controller identifies a universal serial bus (USB) device connected to a USB interface, it outputs a control signal to close a relay and a first start test signal to an electronic device to test a USB interface of the electronic device. When the test of the USB interface is completed, to the controller adds one to an inside counter, and determines whether the count value reaches a preset count value. If the count value reaches the preset count value, the controller outputs a finish test signal to the electronic device. If the count value does not reach the preset count value, the controller controls the closed relay to open and outputs a second start test signal to close a next relay to test a next USB interface of the electronic device corresponding to the now closed relay.

Abstract: Techniques are provided for creating a mapping that maps locations in audio data (e.g., an audio book) to corresponding locations in text data (e.g., an e-book). Techniques are provided for using a mapping between audio data and text data, whether or not the mapping is created automatically or manually. A mapping may be used for bookmark switching where a bookmark established in one version of a digital work is used to identify a corresponding location with another version of the digital work. Alternatively, the mapping may be used to play audio that corresponds to text selected by a user. Alternatively, the mapping may be used to automatically highlight text in response to audio that corresponds to the text being played. Alternatively, the mapping may be used to determine where an annotation created in one media context (e.g., audio) will be consumed in another media context (e.g., text).

Abstract: Animation creation is described, for example, to enable children to create, record and play back stories. In an embodiment, one or more children are able to create animation components such as characters and backgrounds using a multi-touch panel display together with an image capture device. For example, a graphical user interface is provided at the multi-touch panel display to enable the animation components to be edited. In an example, children narrate a story whilst manipulating animation components using the multi-touch display panel and the sound and visual display is recorded. In embodiments image analysis is carried out automatically and used to autonomously modify story components during a narration. In examples, various types of handheld view-finding frames are provided for use with the image capture device. In embodiments saved stories can be restored from memory and retold from any point with different manipulations and narration.

Abstract: An exemplary cabinet for electronic devices includes an enclosure and an overweight alarm device disposed in the enclosure. The enclosure is for accommodating electronic devices therein. The overweight alarm device includes a weighing circuit, an A/D (Analog to Digital) converting circuit, a control circuit and a warning circuit connected in sequence.
