20090293120 | ANTI-THEFT METHOD AND APPARATUS WITH WIRELESS TECHNOLOGIES - An anti-theft method to be executed in an active peer, comprising: (a) transmitting radio RF signals to a passive peer to detect whether one of the active peer and the passive peer as a monitored object is in the coverage area of the radio range of the other one of the active peer and the passive peer as a dock; (b) checking whether the monitored object is permitted to leave the dock when detecting that the monitored object is going to leave the area of the dock; (c) sending an alarm signal to an alarm apparatus if the monitored object is not permitted to leave the dock. | 11-26-2009 |
20110190007 | METHOD AND APPARATUS FOR AUTOMATIC ASSIGNING OF DEVICES - In order to solve problems of low accuracy, high computation complexity and low assigning success rate of a topological graph existing on a large scale for device assigning, the present invention proposes methods and apparatuses for automatic assigning of devices. According to an aspect of the present invention, by comparing measured distance-related information between each target device and reference devices, and assumed distance-related information between reference devices and target devices corresponding to assigning nodes, and then selecting the target device with smallest difference to correspond to the assigning nodes, the assigning accuracy of devices is largely improved; according to another aspect of the present invention, based on multiple reference devices, by determining multiple target devices at multiple assigning nodes simultaneously with a large safety margin, assigning complexity is decreased; according to yet another aspect of the present invention, by dividing a large topological graph into blocks and assigning and verifying sub-topology blocks, the assigning accuracy of sub-topology blocks is improved, and error dispersion is avoided, so that the whole assigning success rate of the topological graph is increased. | 08-04-2011 |
20110234366 | METHODS FOR SELECTING AND CONTROLLING DEVICES - A method of selecting and controlling devices based on wireless communication technology. The wireless controller sends a probe message to one or more devices; each device receives the probe message, obtains information in respect of its relative position with respect to the wireless controller, determines a response time to respond according to a first predefined rule, based on its relative position information: detects response signals from other devices before expiration of the response time; decides whether to send or not to send its response signal according to a second predefined rule and the detecting procedure of response signals from other devices; the wireless controller receives response signals sent by the devices after the comparison of the relative position information of each device with respect to the wireless controller, and selects the target devices from the devices. Embodiments of the present invention reduce the complexity, delay and energy consumption of the selection for wireless devices, and are especially applicable for wireless lighting systems. | 09-29-2011 |

20110287789 | METHOD AND APPARATUS FOR RECOGNITION OF DEVICES - The present invention aims to provide a technical solution for recognizing a target device from a plurality of devices as follows: sending a first and second wireless signal to a plurality of devices and determining the target device according to the signal strength differences between the first and second signal strengths. By using the technical solutions of the present invention, the “near-far-effect” caused by a single antenna can be overcome, and different offsets in the measured received signal strengths caused by the diversity of the receiving antennas can also be eliminated, and thus the accuracy of recognition is improved efficiently. | 11-24-2011 |
20120040624 | DEVICE AND METHOD FOR DETECTING CHANNEL STATE - The present invention proposes a device and method for detecting the channel state. The detecting device first monitors a channel within a predetermined duration so as to receive a plurality of signals transmitted on the channel, and then determines whether part of the plurality of signals possess periodicity. If part of the plurality of signals possesses periodicity, then the detecting device determines that the channel is interfered. Even if there is no or less data traffic over one or more wireless networks which occupy the channel, the detecting device and method provided by the present invention are capable of detecting the existence of the one or more wireless networks, and determine that the channel is interfered, so as to avoid potential interference. In addition, the cost to detect whether a channel is interfered will be reduced effectively by using the detecting device and the detecting method according to embodiments of the present invention. | 02-16-2012 |
