    • A charge pump circuit includes a charge pump having an output voltage. A replica circuit actively matches up and down currents in the charge pump. A charge pump bias current transistor biases the charge pump. The charge pump includes four switches driven by differential UP and DOWN signals. The charge pump includes a first tail current source connected between a supply voltage and two of the four switches that are driven by the differential UP signal, and a second tail current source connected between a supply voltage and two of the four switches that are driven by the differential DOWN signal. The charge pump includes an operational amplifier whose output is connected to an output of one of the tail current sources. A dump capacitor is connected to a negative input of the operational amplifier. The replica circuit includes four transistors, two of which match the first and second tail current sources, and the other two match the switches driven by the differential UP and DOWN signals. The replica circuit includes a second operational amplifier that matches the charge up and down current for varied output voltage. A low pass filter is at the output voltage and includes a resistor-capacitor network.

    • The invention relates to a wireless human-machine interactive device of personal computer including two parts, a display and a base. The display can be independently used separately from the base. The key features are in that: the display output module comprising at least a central processing unit (CPU) and a liquid crystal display (LCD), a main board containing a supply circuit for providing a voltage conversion for the main board and for charging a secondary battery, a backlight board, a touch screen control board, a peripheral interface board comprising all Input/Output (I/O) device interfaces and a secondary battery are mounted on a rear part of the display; an LCD control board and a supply adapter for converting a commercial supply into a direct current (DC) supply and supplying the LCD control board with power is mounted in the base; and the electrical connections between the base and the display are achieved by gilded pins (golden finger) or a multi-pin/multi-jack connector. The present invention can also be applied to a normal liquid crystal display of personal computer. While the inventive wireless human-machine interactive device or liquid crystal display ensures all the other functions, the appearance or the structure thereof is thinner, lighter, and more beautiful with a good visual and practical effect.

    • A system and method are provided for XML query cursor implementation through the steps of query translation and processing, query result navigation, and positioned update. An XML query cursor implemented in Interface Definition Language (IDL) as well as an extension to XQuery, an XML query language, is described. These steps are addressed by one of three approaches: multi-cursor, outer union, or hybrid. In each approach, XML data is assumed to be stored in a relational database with a mapping that maps each element to a row in a relational database table. In each approach, a system and method provide for cursor movements and positioned updates in increments of a node, sub-tree, or entire document. Given a user's navigation patterns, a system and method is provided to select either a multi-cursor, outer union, or hybrid approach as an optimal implementation for an XML query cursor.
