Abstract: Disclosed are a method for selecting an audio output device and a display apparatus. The method includes: in response to a power cutoff command, saving a first device list and performing a first set of operations associated with the power cutoff command; while the display apparatus is in a power off state, receiving a power on command; in response to the power on command, performing a second set of operations associated with a power on process; in response to a first audio output device having connected with the display apparatus, determining whether a first identifier of the first audio output device is same as the identifier of the current sound output device; and in response to the first identifier of the first audio output device being same as the identifier of the current sound output device, taking the first audio output device as the current sound output device.

Abstract: The disclosure provides a display apparatus and a method. The display apparatus includes a display, a communicator, an external device interface, a memory and a processor. The processor is configured for: receiving a command for adjusting an audio state of an external audio output device in connection with the display apparatus; determining a target audio state to which the external audio output device needs to be adjusted by parsing the command; sending, to the external audio output device, an audio state adjusting instruction for adjusting the audio state to adjust a current audio state of the external audio output device to the target audio state and an instruction for requesting audio state to request the external audio output device to send the target audio state to the display apparatus; receiving the target audio state returned from the external audio output device and displaying the target audio state.

Abstract: Disclosed here is a scanning probe microscope system and method for operating the same for producing scanning probe microscope images at fast scan rates and reducing oscillation artifacts. In some embodiments, an inverse consistent image registration method is used to align forward and backward scan traces for each line of the scanning microscope image. In some embodiments, the aligned forward and backward scan traces are combined using a weighting factor favoring the scan trace with higher smoothness. In some embodiments, the scanning probe microscope image is a potentiometry map and a method is provided to extract from the potentiometry map a conductivity map.
