Abstract:
A method and service for enabling a smallest unit of variable data within a data space of a user application to be dynamically updated using an external source. The application GUI is enhanced with a dynamic update utility (DUU) that enables the data unit to be selected and linked to the broker topic. A list of available topics is presented for selection by the user, and the data unit automatically linked to the selected broker topic without requiring user knowledge of the specific linking parameters of the external source. A JMS client application is provided containing a message listener and an application writing protocol. A subscriber is defined for the data unit and subscribes to the particular event broker topic hosted at a JMS provider. When the event broker receives a publication from the data publication source, a copy of the published data is forwarded to the message listener associated with the subscriber, and the message listener provides the data to the application writing protocol. The application writing protocol then automatically overwrites the data unit with the published data.
Abstract:
An improved caller ID system for providing geographic location information about an incoming call to a cell phone is provided. The area code of an incoming call based on the caller ID information is detected and an area code database is accessed within the cell phone or on the cellular network. The corresponding geographic location of the detected area code for the incoming call is retrieved from the database and displayed for the user on the cell phone, either automatically in response to the incoming call or upon actuation of the function by the user.

Abstract:
A liquid crystal display panel and a fabricating method thereof comprising an image sensing capability, image scanning, and touch inputting. In the liquid crystal display device, a gate line and a data line are formed to intersect each other on a substrate to define a pixel area in which a pixel electrode is positioned. A first thin film transistor is positioned at an intersection area of the gate line and the data line. A sensor thin film transistor senses light having image information and supplied with a first driving voltage from the data line. A driving voltage supply line is positioned in parallel to the gate line to supply a second driving voltage to the sensor thin film transistor.
