    摘要: A tracking detection and alarm method which is applied to a navigation device use a number of positioning data points retrieved from a navigation module of the navigation device. A number of deflections and a number of average speeds that correspond to the position data points are calculated and generated. A number of maximum deflections are calculated and generated according to the average speeds. When a deflection of a positioning data point is greater than a maximum safe deflection thereof, one is added to a frequency of unsafe driving instances. When the frequency of unsafe driving instances is greater than a preset threshold value, an unsafe driving alarm is activated.

    摘要: A mobile terminal device includes a detector, a transceiver, an analyzer, an execution module, and a connection module. The detector generates a probing request signal. The transceiver receives signals sent from a plurality of access points (AP). The analyzer retrieves a plurality of Received signal strength Indications (RSSI) of the plurality of APs and workload of the plurality of APs by analyzing the signals. The execution module generates a plurality of indices of the plurality of APs based on an analysis results, and selects one of the plurality of indices as a best comprehensive index. The connection module establishes a connection between an AP corresponding to the best comprehensive index and the mobile terminal device.
