  • Patent number: 11429501
    Abstract: A device and method for traffic monitoring and a non-transitory tangible machine-readable medium for use in the device are disclosed. The device stores a probability model. The device records a packet quantity transmitted by a device under test in a monitoring time period. The device determines that the device under test is in an abnormal state when a probability of occurrence corresponded to by the packet quantity and the monitoring time period is lower than a probability threshold, wherein the probability of occurrence is determined by the probability model.

  • Patent number: 10802551
    Abstract: A hinge mechanism includes a plurality of linkage units, each including a base bar and two rotating assemblies pivotally connected with two carrying sections of the base bar. Each rotating assembly has a synchronous rotation bar, a friction plate and a torsion plate. The friction plate has a first major plate body and a friction increasing portion inclined outwardly from the major plate body. The rotating assemblies are turnable relative to the base bar between unfolded and folded positions. During the turning, the friction increasing portion is gradually overlapped upon and in frictional contact with the torsion plate so as to increase a friction force for providing a stable turning.

  • Patent number: 10341471
    Abstract: A packet analysis apparatus, method, and non-transitory computer readable medium thereof are provided. The packet analysis apparatus stores a plurality of packets whose formats are unknown. The packet analysis apparatus calculates a plurality of cross-correlation values of the packets. The packet analysis apparatus decides at least one group according to the cross-correlation values and at least one first threshold, wherein each group includes a subset of the packets. The packets included in a specific group of the groups define a plurality of bit positions. Each packet included in the specific group has a plurality of bits. For each of the bit positions, the packet analysis apparatus calculates a variation degree of the bits corresponding to the bit positions. The packet analysis apparatus selects the at least one bit position whose variation degree(s) is/are smaller than a second threshold as at least one field boundary of the specific group.
