    摘要: A method for controlling a remote wireless device with a user device includes the user device sending a request message packet to the remote wireless device, where the remote wireless device verifies the request message packet and sends a reply message packet to the user device if the request message packet passes verification. The user device verifies the reply message packet and sends a control message packet to the remote wireless device if the reply message packet passes verification. The remote wireless device verifies the control message packet and sends an acknowledgment message packet to the user device if the control message packet passes verification.

    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.
