Abstract: A method and an appliance for anomaly inspection based on correlations of packets are disclosed. The appliance (1) includes a processing unit (13), a first communication channel (C1), and a second communication channel (C2), wherein the first communication channel (C1) transmits a first packet under a first communication protocol (16) and the second communication channel (C2) transmits a second packet under a second communication protocol (17). The processing unit (13) performs a field breakdown procedure to the first packet and the second packet to respectively obtain multiple packet fields of the two packets, matching relevant fields of the two packets based on a correlation database (15) and computing the correlation of the relevant fields. Therefore, an alarm is made when the correlation of the relevant fields is different from an expected correlation type.

Abstract: A light guide plate is adapted for a backlight module having at least one light emitting device, and the light guide plate includes a light emitting surface, a surface opposite to the light emitting surface, a light incident surface connected with the light emitting surface and the surface, and a plurality of microstructures disposed on the light emitting surface or the surface. 90 percent or more of the surface or the light emitting surface is flat. At least one of the light emitting devices is disposed beside the light incident surface and capable of emitting a light beam. The light incident surface is capable of making the light beam enter the light guide plate and the light emitting surface is capable of making the light beam transmit outside the light guide plate. A backlight module is also provided.
