    摘要： Disclosed is an access control method of an area restricted network system including a central control device and at least one area restricted network. Each area restricted network includes at least a master node. The method comprises a detection step of detecting that an access device has entered into an area restricted network in the area restricted network system; a receipt step of receiving, by a master node in the area restricted network, an authentication information request sent by the access device; a sending step of, in response to the authentication information request, generating and sending the authentication information for the access device by the master node in the area restricted network; and a request step of, by the access device, receiving the authentication information, and then utilizing the authentication information so as to send an authentication request to the central control device.

    摘要： Disclosed is a method of estimating the distance between two nodes. The method includes obtaining an original real-time strength sequence, its elements being strengths of signals between the two nodes at respective time slots of a first time period; conducting multi-scale transform with respect to the original real-time strength sequence so as to acquire plural real-time strength component sequences which are results of the original real-time strength sequence projected onto plural scales; removing at least one burst noise element in each real-time strength component sequence so as to get plural updated real-time strength component sequences; estimating, based on the plural updated real-time strength component sequences and a multi-scale empirical mapping relationship, an empirical real-time distance, the multi-scale empirical mapping relationship being used for expressing correspondence relations between strength components and distance components; and determining, based on at least the empirical real-time distance, a real-time distance between the two nodes.

    摘要： Disclosed is a relative orientation angle calculation method comprising steps of obtaining inertial sensor data of first and second mobile devices, the first mobile device being capable of sending a first signal to the second mobile device; obtaining a sending frequency that the first signal has when the first mobile device sends the first signal to the second mobile device; obtaining a receipt frequency that the first signal has when the second mobile device receives the first signal sent from the first mobile device, the first signal receiving influence of the Doppler effect in a sending process in which the first signal is sent to the second mobile device from the first mobile device; and calculating, based on the inertial sensor data, the sending frequency, and the receipt frequency, a relative orientation angle between the first and second mobile devices.

    摘要： Disclosed is a method of recognizing a user of at least one mobile device by using an imaging device. The method comprises a first obtainment step of obtaining first positional information of the user of the at least one mobile device by using the imaging device; a second obtainment step of obtaining both second positional information and ID information of the at least one mobile device; a comparison step of comparing the first and second positional information so as to obtain a comparison result; and a determination step of determining, based on the comparison result, whether or not to let the ID information of the at least one mobile device be associated with the user of the at least one mobile device.
