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 projection device, a projection system and a method for calibrating projected image are provided. The projection device and an external projection device the same image source and respectively project an image and another image corresponding to the image source. The same portion of the image source where the two images overlap each other forms an overlapping area. The projection device includes a lens, a light shielding member and a processor. The light shielding member is disposed on the lens. The processor controls the light shielding member to selectively shade a partial area of the lens according to the brightness of the image source, wherein the partial area corresponds to the overlapping area.

Abstract: A method for controlling a display device includes establishing a data link between the display device and a hardware dongle, generating a second interface by the display device through the hardware dongle after the data link is established, generating a control signal by the display device through the second interface, and executing at least one function according to the control signal. A first interface is stored in the display device. The first interface and the second interface are different. At least one first function is supported by the display device. At least one second function is supported by the hardware dongle. The at least one first function and the at least one second function are integrated for generating the second interface by the display device after the data link is established.
