Patent ID: 7249023

Claim:
An industrial human-machine interface device, comprising: an integrated circuit including a speech-recognition processor operable to convert a speech pattern to an identification word representing said speech pattern; a microcontroller operatively coupled via an interface bus to said speech-recognition processor to receive said identification word from said speech-recognition processor; a display operatively coupled to said microcontroller; an interface operatively coupled between said microcontroller and a power metering device that monitors at least one predetermined characteristic of a power signal; and a first memory storing instructions, said first memory being coupled to said microcontroller, said instructions when executed by said microcontroller causing said display to be altered in response to one or more predetermined spoken keywords recognized by said speech-recognition processor, said predetermined spoken keywords including power-related keywords each corresponding to different predetermined characteristics of said power signal, said predetermined characteristics including at least one of power, voltage, current, energy, frequency, or total harmonic distortion, said instructions further causing said at least one predetermined characteristic to be provided to said microcontroller via said interface.
