The first body includes a main portion and an edge portion, wherein the thickness of the edge portion is smaller than the thickness of the main portion, and the edge portion has an opening. The driving component and the connector module are slidably disposed in the first body and so that the driving component drives the connector module to move from the main portion to the edge portion and the connector module is exposed from the opening of the edge portion.

Abstract: 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.

Abstract: 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.

Abstract: A multi-path data dissemination method for a magnetic diffusion wireless network and a system thereof overcome environmental interferences in wireless data transmissions. Each node of the network is provided for figuring out its good neighbors by broadcasting a good-neighbor exploratory message in a bootstrap process. Each node keeps a good-neighbor table containing nodes with a RSSI higher than a threshold of the good-neighbor table. A magnetic field of a magnetic diffusion (MD) dissemination method capable of determining a data dissemination path is created according to the good-neighbor tables to ensure that the data can be forwarded to a data sink successfully.

Abstract: An indoor localization method is implemented using an indoor localization system that includes beacons deployed in an indoor space and transmitting localization signals, and a radio badge for receiving the localization signals. The indoor localization method includes forming signal vectors from the localization signals received by the radio badge at each of predetermined locations in the indoor space, and generating a signal ID value from the signal vectors for each beacon from which the radio badge has received the localization signals. During a tracking phase, signal vectors are formed from the localization signals received by the radio badge at a current location. If the number of the signal ID values is smaller than the number of the signal vectors, the sum of the signal distances is normalized by the number of the signal ID values. An estimated position of the radio badge is obtained using the signal vectors and the signal ID values.

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.
