Abstract: A master-slave card system includes a master card and a plurality of slave cards connected in serial. The master card sends a command with a station-number information to the slave cards. A selected slave card designated by the station-number information sends back a response message, where the response message includes an initial packet, a plurality of data packets and a CRC check packet. The master card sends a next command to a next slave cards after the master cards identifies a correct initial packet. When the initial packet is not correct, the master card halts sending the next command until the received signal is already stopped for a predetermined silence time. The master card drops all the data packets if the CRC check packet associated with the data packet is not correct.

Abstract: A liquid crystal displayer for preventing the generation of moisture includes a front cover, a touch panel, a nameplate, a partitioning plate and a liquid crystal displayer module. With the partitioning plate dividing a region between the touch panel and the liquid crystal displayer module into a first space and a second space, the first space is smaller, whereas the second space is larger. After the liquid crystal displayer module is supplied with electricity, the hot air staying in the first space is less. Further, the heat-obstructing effect of the partitioning plate causes the hot air not to condense in the second space, and thus it is not easy to generate a temperature difference from the external environment, thereby preventing the generation of mist.
