Abstract: A backlight module includes a light guide plate, a light source, a first prism sheet, and a second prism sheet. The light source is disposed on a light incident surface of the light guide plate. The first prism sheet is disposed on a side of a light exiting surface of the light guide plate and has multiple first prism structures facing the light guide plate. The second prism sheet has multiple second prism structures facing the light guide plate. An included angle between an extending direction of the first prism structures and an extending direction of the second prism structures is greater than or equal to 85 degrees and less than or equal to 95 degrees. An included angle between the extending direction of the second prism structures and the light incident surface is greater than or equal to 85 degrees and less than or equal to 95 degrees.

Abstract: A method of spectral analyzing with a color camera is provided, and the method includes: calibrating a color camera to obtain a quantum efficiency database of the color camera; shooting a detection area with the color camera, the detection area including at least one object, to obtain the color content data of the at least one object; and comparing the color content data to the quantum efficiency database to analyze the at least one object.

Abstract: A system for checking the validity of data transmission includes a data transmitting computer (1), a data receiving computer (2), and a network (3). The data transmitting computer is used for generating a check-code of original data, and sending a data packet, which includes the original data and the check-code, to the data receiving computer via the network. The data transmitting computer includes a shift operation unit (111), an addition operation (112) unit, a complement operation unit (113), and a control unit (114). The data receiving computer is used for receiving the data packet from the data transmitting computer, and determining whether the data packet is valid. The data receiving computer includes a shift operation unit (211), an addition operation unit (212), and a control unit (213). A related method is also disclosed.

Abstract: An electronic device (120) includes: an input connector (121), including at least three address pins and plural data pins; a function chip (123), including address pins and data pins corresponding to those of the input connector, and directly connected to the input connector by the data pins thereof; an adder disposed between the input connector and the function chip, and including at least three input pins and at least three output pins, the input pins being connected to the address pins of the input connector of the electronic device in one-to-one correspondence, the output pins being connected to the address pins of the function chip; and an output connector (124), including at least three address pins and plural data pins, the address pins being connected to the output pins of the adder in one-to-one correspondence, the data pins being respectively connected to the data pins of the input connector.
