Abstract: A vibration sensor senses vibrations generated by an object to generate a noise signal. A processor obtains a structure vibration level spectrum from the noise signal, uses equalization parameters and A-weighting parameters to adjust the structure vibration level spectrum to generate a sound pressure level spectrum, and uses the sound pressure level spectrum to calculate a noise value of the object.

Abstract: A video conferencing system is disclosed. The video conferencing system includes a transmitter and a receiver. When the transmitter is coupled to a port of an information processing device, the transmitter communicates with the information processing device to determine whether the port of the information processing device has video output function. When the above determination result is no, the transmitter emits a wireless signal. The transmitter is coupled to a display device and used to receive the wireless signal and provide a default warning message to the display device.
