Methods and devices of multi-functional operating system for care-taking machine

A method for constructing and processing potential images, used to process, analyze, and identify the electric signals detected by detecting devices;

• said construction and processing method further comprises the following steps:
• forming digitized electric signals—signals detected processed by said multi-task amplifying filter and said analog-to-digital converter to become digitized electric signals;
• constructing potential images—image processing unit received digital electric signals and convert them into grey scale pixel signals to form specific potential images;
• pre-processing said images—characteristics of said potential images are highlighted to identify iso-potential lines and iso-potential points;
• grouping said images—after the characteristics were highlighted, said potential images are grouped, according to their characteristics, and tallied with those in the muscle template database;
• generating movement commands—after said images are grouped and tallied with said muscle template database, movement commands are given to said control bus to conduct various controls of said care-taking machine;
• and
• obtaining the next step—after the above control cycle is completed, the next step goes back to said potential image construction step and starts the next control cycle.

A method for multi-functional control interface for care-taking machine, which is used to construct an interface that provides the user with high degree of freedom and instant controllability that the user can use any movable parts of the body to exert highly free control of an equipment, comprising the following steps:

• detecting operation movements—detect the movements on the movable parts of the user's body and generate corresponding electric signals;
• amplifying and filtering electric signals detected by the above step and then output analog signals;
• converting said analog signals into digital electric signals;
• processing images—arranging and converting said digital electric signal generated by said A/D converting step into gray level potential images, and processing said potential images and grouping them according to characteristics highlighted;
• outputting control commands—a muscle template database provides a set of characteristics for tallying with those highlighted in the above step;
• after that, said muscle template database presents a corresponding commands;
• and
• transmitting control commands—a control bus receives the commands outputted in the above step and transmit said commands to related interface, signal converter, or control unit so as to control a specific equipment.
