| 20090141899 | DUAL-MODE WIRELESS SENSOR NETWORK SYSTEM AND KEY ESTABLISHING METHOD AND EVENT PROCESSING METHOD THEREOF - A dual-mode wireless sensor network system including a local wireless sensor, a local event processing device, and a remote event processing device is provided. The local wireless senor detects and announces an abnormal event. The local event processing device and the remote event processing device receive the abnormal event announcement. When the local wireless senor detects the abnormal event, the local wireless sensor encrypts an abnormal event message related to the abnormal event with a regular mode key and transmits the encrypted abnormal event message to the local event processing device. When the local wireless sensor does not receive a response message from the local event processing device, the local wireless sensor encrypts the abnormal event message with a special mode key and transmits the encrypted abnormal event message to the remote event processing device. Thereby, the abnormal event can be successfully announced even with highly protected privacy. | 06-04-2009 |
| 20100141423 | WIRELESS SENSOR NETWORK AND DATA SENSING METHOD THEREOF - A wireless sensor network and data sensing method thereof are provided. A prediction model is established according to sensed data. When statistical value of the sensed data is within a user allowable range, the average value of the sensed data is returned to a user based on the prediction model. Alternatively, when the statistical value of the sensed data is beyond the user allowable range, actually sensed data is returned to the user based on the prediction model. In addition, the prediction model may further be dynamically updated according to subsequently received sensed data. | 06-10-2010 |
| 20100146280 | REMOTE ASSISTING METHOD AND SYSTEM - A remote assisting method is applied in a remote assisting system, which includes a server, a help-asking device and a helping device. The remote assisting method includes the following steps. First, ticket information is encrypted into encrypted ticket information, which is provided to the server, in response to a help-asking event and according to a first key. Next, the encrypted ticket information provided by the help-asking device is decoded into the ticket information according to a second key. Then, the ticket information, generated by decoding, is provided to the helping device such that the helping device can log in the help-asking device and perform a remote assisting operation. | 06-10-2010 |
| 20100150048 | MULTICAST COMMUNICATION METHOD, ACCOMPANIED WITH THE RELAY NODE AND WIRELESS NETWORK SYSTEM DESIGN - A multicast communication method for relaying a multicast packet from a first member node to a plurality of second member nodes in a wireless network is provided, wherein the first member node and the second member nodes belong to a same group and can communicate with each other via a plurality of non-member nodes. In the multicast communication method, a number and distances of the second member nodes are recorded. The multicast packet is received from the first member node, and a waiting time is determined according to the number and the distances of the second member nodes. Whether the multicast packet is broadcasted by any other relay node is monitored during the waiting time. If the multicast packet is already broadcasted to all the second member nodes by other relay node, the multicast packet is not broadcasted; otherwise, the multicast packet is broadcasted after the waiting time elapses. | 06-17-2010 |
| 20110032152 | Method and Apparatus for Positioning Mobile Device - A method for positioning a mobile device includes following steps. Based on a prior location point of the mobile device, many sample particles are generated according to a prior probability distribution associated with the prior location point. A current moving track or a current behavior mode of the mobile device is obtained, and the sample particles are moved according to at least one of the current moving track and the current behavior mode. A current supposed status is obtained based on a radio frequency signal received by the mobile device. A current probability distribution of the sample particles corresponding to the radio frequency signal or the current supposed status is generated to obtain corresponding weights of the moved sample particles. A current location point of the mobile device is obtained according to the weights and distribution of the sample particles. | 02-10-2011 |
| 20110055280 | Wireless Sensing System and Method Thereof - A wireless sensing system and a method thereof are provided. The wireless sensing system includes: a data processing center; and a first sensor module for processing a first source data into a first dynamic counting sketch data structure. The first dynamic counting sketch data structure has a bit length determined based on the first source data. The data processing center estimates the first source data based on the first dynamic counting sketch data. | 03-03-2011 |
| 20110072143 | SCHEDULING METHOD FOR PEER-TO-PEER DATA TRANSMISSION AND NODE AND SYSTEM USING THE SAME - A scheduling method for peer-to-peer data transmission suitable for a peer-to-peer system is described. The peer-to-peer system comprises a plurality of nodes, and the nodes comprise an i | 03-24-2011 |
| 20110092222 | VECTORING SERVICE INITIATION SYSTEM AND METHOD BASED ON SENSOR ASSISTED POSITIONING - A system and a method for vectoring service initiation, such service initiation can be data transfer, game initiation, media download, media streaming initiation, house application and the like, based on sensor assisted positioning are provided, which employ location sensors built in hand-held devices with positioning technology to provide an instinctive 2-D or 3-D user-machine interface, by that the user is able to transfer a file from a source device to a target device. | 04-21-2011 |
