Abstract: A method for calibrating performance of a small array microphone is provided. The small array microphone includes at least two microphones. The method includes: measuring parameters of the microphones; recording the parameters in a storage media; and calibrating acoustic performance of the array microphone according to the parameters recorded in the storage media.

Abstract: A method for showing an array microphone effect includes the steps of obtaining an original acoustic signal from array microphones, and visualizing the original acoustic signal to obtain a figure. The original acoustic signal includes a crystal voice, out-beam noises, background noise, and/or an echo. The figure includes a plurality of graphic components representing the crystal voice, out-beam noise, background noise, and/or echo, respectively.

Abstract: A voice recognition system and method thereof. The communication system comprises a setup controller, a voice recognition controller, and an application controller. The setup controller receives a voice keyword table including a voice recognizable keyword and a corresponding application instruction. The voice recognition controller, coupled to the setup controller, receives the voice keyword table from the setup controller, receives a first voice input, and matches a first voice input to the voice recognizable keyword to determine the corresponding application instruction. The application controller, coupled to the voice recognition controller, receives and performs the corresponding application instruction. The setup controller, the voice recognition controller, and the application controller communicate through wireless communication.

Abstract: An improved voice recognition system in which a Voice Keyword Table is generated and downloaded from a set-up device to a voice recognition device. The VKT includes visual form data, spoken form data, phonetic format data, and an entry corresponding to a keyword, and TTS-generated voice prompts and voice models corresponding to the phonetic format data. A voice recognition system on the voice recognition device is updated by the set-up device. Furthermore, voice models in the voice recognition device are modified by the set-up device.

Abstract: An electro acoustic system built-in test and calibration method utilizes a built-in self-test module to send a test signal through a first circuit device to an audio transmitter, causing the audio transmitter to output a test signal, for enabling the test signal to be received by a audio receiver and then processed by a connected circuit device and converted into a feedback digital signal to the self-test module for comparing the linearity relative to the originally provided test signal so that the parameter values and conformity of circuit devices can be optimized subject to comparison result. The test and adjustment procedure is recycled for other parameter items, and a warning signal is produced when proper adjustment cannot be done.

Abstract: A self-unloading bed includes a conveyor with chain bars that are strong, light-weight and non-damaging to the floor upon which the conveyor slides. The preferred chain bar is an elongated bar with two legs, each of said two legs having a foot. The feet extend away from the leading (unloading) direction, the transition from leg to foot being formed by smooth bends, so that no sharp edges exist that would gouge into the floor as the chain bar moves across the floor. The preferred chain bar, made of a single metal bar with four longitudinal bends, is extremely strong for its weight, and it unlikely to bend or gouge into the floor during use.
