Methods and systems that record the location of a user and transmit targeted content to a user based upon their current and past location information. A network is configured to include a server programmed with a database of targeted content, a database of location information, a database of user information, a database searching algorithm, and a wireless communication system capable of communicating with the user's mobile device. The location of the mobile device is ascertained and recorded. The location information is analyzed to determine the routes taken by the user, businesses visited by the user, and other behaviors of the user. Targeted content is sent to the mobile device of the user and whether the user visits the physical locations associated with the targeted content is monitored. Payment systems, phone exchange systems, and other features may also be integrated to provide detailed conversion tracking to producers of targeted content and business owners.

Data monitoring means adds tag information representing a document conversion method to hyperlink information included in a hypertext type document sent to a user-side device from a server-side application, and sends to the user-side application the hyperlink information to which the tag information is added.

The invention discloses a state conversion method, and a state keeping method and device, and belongs to the technical field of communications. The method comprises the following steps: when user equipment is under an unactivated state and satisfies a first predetermined condition, converting the user equipment into an idle state from the unactivated state; when the user equipment is under the unactivated state and satisfies a second predetermined condition, keeping the user equipment under the unactivated state; and when the user equipment is under the unactivated state and satisfies a third predetermined condition, converting the user equipment into a connected state from the unactivated state, wherein the unactivated state is an intermediate state between the connected state and the idle state. The state conversion method, and the state keeping method and the device provided by the invention solve the problem that when the UE (User Equipment) receives and sends small data packet services in 4G (the 4th Generation mobile communication technology), the UE needs to switch between an RRC (Radio Resource Control) connected state and an RRC idle state back and forth to lead to signaling resources waste, thereby achieving the effects that the UE can receive and send the small data packet services under the unactivated state, and the signaling resources are saved.

An example-based 2D to 3D image conversion method, a computer readable medium therefor, and a system are provided. The embodiments are based on an image database with depth information or with which depth information can be generated. With respect to a 2D image to be converted into 3D content, a matched background image is found from the database. In addition, graph-based segmentation and comparison techniques are employed to detect the foreground of the 2D image so that the relative depth map can be generated from the foreground and background information. Therefore, the 3D content can be provided with the 2D image plus the depth information. Thus, users can rapidly obtain the 3D content from the 2D image automatically and the rendering of the 3D content can be achieved.

This invention provides a computer-method for parsing by enabling scripts to be expressed in a language which is syntax-compatible with the document surrounding them. A document is loaded having script and non-script components. Script components are identified and delineated, and are then passed to an interpreter, which returns an object corresponding to each script component. Then, script elements in the original document are replaced with the last returned object from the interpreter. If the returned object is a suitable Document Object Model (DOM) Node, it replaces the script element in the document structure. If the object is not a DOM node, the server invokes its string conversion method to obtain a textual representation, and replaces the script element with that text. After all BML markup block elements in the document have been processed, the altered document is delivered to the client.

Methods and apparatus for use in reducing power consumption in battery-powered mobile communication devices in wireless local area networks (WLANs) are described. In one illustrative example, a mobile device in a WLAN is configured to normally refrain from receiving broadcast messages so that it may remain in a low power mode of operation. A network server is configured to convert broadcast messages into unicast messages for receipt by the mobile device only if the message or protocol type of the broadcast message is one in which the mobile device needs to process. As the mobile device is still configured to receive unicast messages, it will receive and decode such a unicast message and process the broadcast information within it accordingly. Advantageously, battery power is conserved at the mobile device.

An apparatus for thermal conversion of one or more reactants to desired end products includes an insulated reactor chamber having a high temperature heater such as a plasma torch at its inlet end and, optionally, a restrictive convergent-divergent nozzle at its outlet end. In a thermal conversion method, reactants are injected upstream from the reactor chamber and thoroughly mixed with the plasma stream before entering the reactor chamber. The reactor chamber has a reaction zone that is maintained at a substantially uniform temperature. The resulting heated gaseous stream is then rapidly cooled by passage through the nozzle, which "freezes" the desired end product(s) in the heated equilibrium reaction stage, or is discharged through an outlet pipe without the convergent-divergent nozzle. The desired end products are then separated from the gaseous stream.
