Abstract: A backup architecture for a backlight module comprises a first power system and a second power system, each having an enable mode and a disable mode; and a sensor unit, electrically connected to the first and the second power systems. In the enable mode, the first power system or the second power system is enabled to drive the backlight module to emit light. In the disable mode, the first power system or the second power system is disabled and stops driving the backlight module. The first and the second power systems are interconnected in parallel. When one of the first power system and the second power system enters into the enable mode, the other enters into the disable mode. The sensor unit acquires the working signals of the first and the second power systems and monitors whether the first power system or the second power system is in an abnormal state.

Abstract: A keyboard without ghost keys has a circuit which includes a microprocessor in which a plurality of I/O lines form a keyboard scanning matrix. Two of the I/O lines on the matrix cross to define a plurality of signal switches. The microprocessor is electrically connected to a primary level resistance and a reference potential to determine the ON condition of the signal switches. Each signal switch further is electrically connected to at least one secondary level switch which is electrically connected to the primary level switch in a serial manner. When a user depresses any three signal switches on the rectangular angles of the keyboard scanning matrix, the connecting primary level resistance and the secondary level resistance form a new level resistance. The new level resistance and the current flowing to the keyboard scanning matrix are processed to get a potential smaller than the reference potential, thereby to eliminate the phenomenon of ghost keys.

Abstract: An architecture effectively connecting a rotary switch and a casing comprises: a rotary switch and a casing that is engaged with the rotary switch via a rotary disc of the rotary switch. The casing has multiple snap-fit parts corresponding to snap-fit slots of the rotary disc to form a snap-fit interconnection therebetween. When the casing is rotated, the casing will drive the rotary switch to rotate via the interconnection between the snap-fit parts and the snap-fit slots, and a signal module will output instructions corresponding to the rotation track of the rotary disc. The interconnection between the casing and the rotary disc is implemented with a snap-fit method, and the rotated casing drives the rotary disc to rotate synchronically and create signals. As the casing is engaged with the rotary disc via a snap-fit method, the casing is hard to deviate or loosen. Thus, correct instructions will be exactly output.
