Systems, articles, and methods perform gesture identification with limited computational resources. A wearable electromyography (“EMG”) device includes multiple EMG sensors, an on-board processor, and a non-transitory processor-readable memory that stores data and/or processor-executable instructions for performing gesture identification. The wearable EMG device detects and determines features of signals when a user performs a physical gesture, and processes the features by performing a decision tree analysis. The decision tree analysis invokes a decision tree stored in the memory, where storing and executing the decision tree may be managed by limited computational resources. The outcome of the decision tree analysis is a probability vector that assigns a respective probability score to each gesture in a gesture library. The accuracy of the gesture identification may be enhanced by performing multiple iterations of the decision tree analysis across multiple time windows of the EMG signal data and combining the resulting probability vectors.

Systems, articles, and methods perform gesture identification with limited computational resources. A wearable electromyography (“EMG”) device includes multiple EMG sensors, an on-board processor, and a non-transitory processor-readable memory storing data and/or instructions for performing gesture identification. The wearable EMG device detects signals when a user performs a physical gesture and characterizes a signal vector {right arrow over (s)} based on features of the detected signals. A library of gesture template vectors G is stored in the memory of the wearable EMG device and a respective property of each respective angle θ_i formed between the signal vector {right arrow over (s)} and respective ones of the gesture template vectors {right arrow over (g)}_i is analyzed to match the direction of the signal vector {right arrow over (s)} to the direction of a particular gesture template vector {right arrow over (g)}*. The accuracy of the gesture identification may be enhanced by performing multiple iterations across multiple time-synchronized portions of the EMG signal data.

A method and system provide for entering text into a text field by determining complete-text terms, displaying the complete-text terms, and receiving a selection of a complete-text term as text to be entered into the text field. In some cases, a complete-text term can include all prior text entries used to determine the complete-text terms. In other cases, a complete-text term can include only a portion or none of the prior text entries used to determine the complete-text term. The determination of the complete-text terms can be based on a vehicle identifier. The determination of the complete-text terms can be based on one or more complete-text term selection-limiters, such a location, use, or diagnostic trouble code associated with the vehicle. The system can include a vehicle service tool that requests a set of complete-text terms and receives the set from a complete-text term storage device or an off-board processor.

According to the system disclosed by the invention, an interrupt processing module function is increased on CPLD between a master control board and an interface board, and the operation of interrupt state and control register between the master control board and the interface board is realized by utilizing two serial signal lines. All interrupt states of the interface board are reported to the CPLD of the master control board in a serial bus manner, the master control board processor only needs to execute once and perform bus access when interrupt happens, and the interrupt state is acquired from the CPLD of the master control board. Therefore, instruction per cycle allowing the processor to access peripherals is greatly reduced, load of the processor is reduced, and the interrupt response time is accelerated. The interrupt needs to be transferred between the interface board and the master control board by two signal lines only, and signal pins are greatly saved.
