Abstract
In an application system of a liquid crystal display, for protecting transmissions between a master terminal and a slave terminal, effects caused by an unstable power source of the slave terminal have to be reduced to a lowest degree. When the application system is reset or under normal operations with the power source having a suddenly-decreased or suddenly-unstable voltage level, the transmission between the master terminal and the slave terminal have to be terminated, and related data of the terminated transmission is temporarily stored. When the voltage of the slave terminal is confirmed to reach to a stable voltage over a predetermined duration, the transmission may be restored by the stored data.
Claims18
An information protecting method applied on a master terminal and a slave terminal in a system, comprising:
- (a) detecting if a voltage level of a power of the slave terminal is lower than a reference voltage;
- and
- (b) if the voltage level of the power of the slave terminal is lower than the reference voltage, storing a data related to a transmission between the master terminal and the slave terminal, and terminating the transmission.
A system for protecting an information, comprising:
- a slave terminal having a power terminal coupled to a power;
- a master terminal for accessing information of the slave terminal;
- and
- a detecting device for detecting the voltage level at the power terminal of the slave terminal, and for performing a detecting/protecting mechanism;
- wherein the master terminal terminates or restores transmission between the master terminal and the slave terminal according to results of the detecting/protecting mechanism.
