    摘要: A frequency hopping method for localization system is aimed to overcome the degradation of location accuracy due to radio interference if there are some other radio devices using the same radio frequency as a localization system. A Packet Reception Rate (PRR) thresholding or a learning-based approach for the diagnostic test is proposed. In that, a PRR thresholding or a set of parameters trained by Hidden Markov Model (HMM) is used as a criterion to decide whether or not to hop. The proposed hopping mechanism provides an accurate and stable localization with a minimum delay.

    摘要: A method of reducing power consumption of a radio badge in a boundary detection localization system is disclosed, in which the radio badge is carried by a tracked target and performs location sampling communication with an infrastructure component of the localization system at the start and end of sampling time intervals such that positions of the radio badge can be estimated. The method includes: determining a velocity of the radio badge; estimating a critical time for the radio badge to reach a critical region through division in which a critical distance from an estimated position obtained at the end of a most recent sampling time interval to the critical region is the dividend, and the velocity of the radio badge is the divisor; and controlling the radio badge to perform location sampling communication with the infrastructure component of the localization system at the end of the critical time.

    摘要: An indoor localization method is implemented using an indoor localization system that includes beacons in an indoor space and each periodically transmitting a localization signal, a radio badge receiving the localization signals, and a host coupled to the beacons and the radio badge. The beacons transmit the localization signals asynchronously. The indoor localization method includes a training phase and a tracking phase. During the training phase, signal vectors are formed from the localization signals received by the radio badge, and a signal ID value is generated from the signal vectors. During the tracking phase, signal vectors are formed from the localization signals received by the radio badge at a current location. An estimated position of the radio badge is obtained using the signal vectors of the tracking phase and the signal ID values.

    摘要: An embodiment of present disclosure provides a state tracking system via a social network interface comprising a detecting module, a state information processing module, and a social network interface. The detecting module can detect at least one tracking target according to a detecting frequency to obtain the state information of the tracking target. The state information processing module can receive the state information and determine whether the present state information of the tracking target is different from the previous state information of the tracking target. If the present state information is different from the previous state information, the state information processing module releases the present state information on the social network interface. If the present state information is the same as the previous state information, the state information processing module does not release the present state information on the social network interface.

    摘要: The present invention relates to a system, and a method for time synchronization with low power consumption and high accuracy. The system comprises a plurality of devices for time synchronization. Each device comprises a GPS receiver, a microprocessor, and an oscillator. The microprocessor generates a drift per second according to the difference between the PPS signal and the clock signal, and calibrates the clock signal constantly according to drift per second. The GPS receiver is turned off when the drift per second is obtained, and then is turned on after a pre-determined time period for updating the drift per second.

    摘要: An operation method and a radio device for controlling power switch of radio based on moving speed are provided. The radio device comprises a speed estimator and an operator. The speed estimator is used for estimating the moving speed of the radio device, and the operator is used for comparing the moving speed of the radio device with a speed threshold value so as to turn on/off the power switch of the radio device. Thereby, the power switch of the radio device can be controlled based on the moving speed so as to decrease the time the radio device staying on, thus reducing the power consumption of the radio device.
