  • Publication number: 20120061650
    Abstract: A transistor structure comprises a patterned N-type transparent oxide semiconductor formed over a substrate as a base, and a patterned p-type organic polymer semiconductor formed on the patterned N-type transparent oxide semiconductor comprising a first portion and a second portion so that the patterned N-type transparent oxide semiconductor and the first portion and the second portion of the patterned p-type organic polymer semiconductor form heterojunctions therebetween respectively, wherein the first portion of the patterned p-type organic polymer semiconductor is used as an emitter, and the second portion of the patterned p-type organic polymer semiconductor is used as a collector.

  • Publication number: 20110296530
    Abstract: Present invention relates to an electronic reading apparatus with data security and anti-theft functions. The electronic reader apparatus has a code input unit for receiving a security code, and a code determining unit for determining an authenticity of the security code. When no security code, no authentic security code or even no operational signal has been received during the predetermined periods of time, a central control unit may stop a power supply unit from outputting power in order to turn off the electronic reader apparatus and clear the image shown on a display unit. As such, a content of sensitive or confidential data stored in the electronic reading apparatus may not be intruded.

  • Publication number: 20110217687
    Abstract: An examination system and an examination method are disclosed. The examination method includes: generating a first test data by a host device, in which the first test data has a plurality of questions; rearranging the questions of the first test data in order to generate a second test data; and sending the second test data to a corresponding examination device for taking the examination. An anti-cheating module is provided for detecting distances between the examination devices or detecting a deviation angle of a character image of the examinee. When the distance is less than a predetermined value or the deviation angle is greater than a predetermined value, an anti-cheating signal is then generated for avoiding cheating actions.
