Abstract: A mobile communication device comprises a communication unit and a processor. The communication unit initiates a wireless communication channel within a range. The processor coupled to the communication unit automatically determines if a server offering point of interest (POI) data exists in the range. If so, the communication unit initiates a wireless communication channel with the server and downloads the POI data therefrom.

Abstract: A System of dynamically displaying an associated message in a message employed in a handheld data processing device, including a multimedia database storing a plurality of sets of multimedia data, a keyword identification module capable of identifying the content of a draft message and a sent message based on a predetermined keyword list to generate a set of keyword information, a keyword search module searching a set of multimedia data corresponding to the set of keyword information from the multimedia database and an associated message prompt module generating the associated message based on the searched set of a set of multimedia data and displaying the associated message on the handheld data processing device.

Abstract: A wireless tire pressure monitoring device has a detecting device and an air tap bonded to the detecting device. The detecting device has a flat box, in which an emitting circuit board is received, and a lid to close the box, and the air tap has a tube, a cover on a free end of the tube and a bolt, in which air flows, to secure an end the tube on a middle section of the box of the detecting device, such that the detecting device and the air tap are mounted between a rim and a tire. An aerial is embedded in the box of the detecting device to combine the aerial and the box as a single element.

Abstract: A data structure for a point of interest (POI) and a method for use and application of POI information with the data structure, and is applied in a handheld device. The POI information for a single POI is sorted based on attributes of the POI and the sorted sets of POI information are included in folders, file names or POI information. As such, when a locating operation for the POI information is requested, the amount of operations for locating the handheld device may be reduced and processing thereof may be sped up. Further, the sorting technology with respect to the POI information corresponding to the POI may be performed based on an attribute district of the POI. A plurality of sets of POI information thus obtained may be compressed to a single set of POI information so that the total information stored in the handheld device may be reduced.

Abstract: An ejector mechanism for a memory card connector includes a plate defining a guiding groove therein, a push bar, a leaf spring, a slider, a spring and a case. The slider provides a guiding pin and an elongate hole on opposite ends thereof. The plate defines a recess and forms a raised portion and a dowel in opposite ends of the recess. The dowel of the plate can move forward and backward within the hole. The end of the slider including the guiding pin approaches the raised portion when the guiding pin is located at a predetermined position of the groove of the plate for preventing the guiding pin from being misguided in the groove.
