  • Publication number: 20220132465
    Abstract: Method for scheduling paging in telecommunication network making the list candidate base station to send paging message. This method based on the Haversine formula to calculate distance between pair of base station from position information (latitude, longitude) and filter by situation: Distance=<?*Min (which ? is 3) to make the list candidate base station for each of base station in list input. This method is useable for the telecommunication system which need to page UE for mobile terminated (MT) service.

  • Publication number: 20200356581
    Abstract: The disclosed embodiments provide a system for estimating transit times. During operation, the system selects one or more transit time thresholds that fall within a transit time preference for a user. Next, the system obtains one or more isochrones representing the one or more transit time thresholds for a starting point associated with the user and a mode of transportation. The system then compares locations of a set of entities to the one or more isochrones to calculate transit times between the starting point and the set of entities. Finally, the system outputs, based on the transit times, one or more recommendations comprising one or more entities in the set of entities that meet the transit time preference.

  • Publication number: 20100090792
    Abstract: In one aspect of the present invention, subminiature fuses are soldered to a PCB via clips attached to the fuse end caps. The clips are physically attached to the PCB pads, enabling the fuse to be replaced if needed and providing thermal decoupling between the fuse and the heating sinking solder/PCB pads. The fuse and clips can also be picked and placed in one operation. In another aspect, improved fuse clips are provided that include tabs that separate the housing portions of the clips from the heating sinking solder/PCB pads. Such improved clips further enhance thermal decoupling. In a further aspect, an improved fuse is provided, in which the thermal decoupling tabs just described are provided directly with the fuse. In yet a further aspect, a thermally insulative fuse body is provided to further decouple the fuse element from its surroundings.

  • Publication number: 20070183599
    Abstract: Security key distribution techniques using key rollover strategies for wireless networks are described. A number of keys are generated, usually by an access point. The present invention allows a standard mode and a mixed mode. In standard mode, each device on the network supports automatic key updates. In mixed mode, one or more devices on the wireless network require fixed keys. In both modes, a predetermined number of keys are determined and communicated to client devices that are accessing the wireless network. The predetermined number is determined so that a client device can miss a certain number of authentication periods without losing communication with the wireless network. Preferably, transmit keys used by an access point are different than the transmit keys used by the client devices that support automatic key updates.

  • Patent number: 6868280
    Abstract: A method of changing an alphabetic character to a variant character when entering information or messages in a mobile phone or a game console or the like. The variant character can be a diacritical variation or a tonal variation of the alphabetic character. After an alphabetic character is entered and displayed on a display device, the star key in the keypad can be used to replace the displayed alphabetic character with a desired one of the variants.
