Disclosed are methods and systems for state switching. The method is applied to a first hardware system. The first hardware system is connected with a second hardware system. The first hardware system has a first operation state and a second operation state. The second hardware system includes a memory unit. The memory unit has a first access state and a second access state. The memory unit is in the first access state currently. The method includes: the first hardware system sends an access state switching instruction to the second hardware system when the first hardware system enters the second operation state from the first operation state, wherein, the access state switching instruction is adapted to switch the memory unit of the second hardware system from the first access state to the second access state. The application of the present invention can ensure the security of key data, avoid the access of key data by malicious software, reduce the implementation costs and has a higher extensibility.

Methods and systems for state switching

The present invention discloses a wearable signal input apparatus for a data processing system comprising a wearable unit at least having a index finger sleeve and a middle finger sleeve; a position sensing unit located on said wearable unit for detecting a movement of the index finger and generating a corresponding displacement signal; a first and a second buttons respectively located on the index finger sleeve and the middle finger sleeve of said wearable unit for generating button signals; a signal processing unit provided on said wearable unit for receiving said displacement signal and said button signals and converting said signals into signals which are recognizable by a signal processing system; a signal transmission unit connected to said signal processing unit for transmitting said recognizable signals to said signal processing system; an input switch unit provided on said wearable unit and connected to said signal processing unit for turning said signal input apparatus on/off. The present invention may conveniently achieve the switching interoperation with other input devices and improve efficiency of the signal inputs.
