A method for waking up a smart device includes receiving sound information; determining whether the sound information includes a multi-frequency tone; and when the sound information includes the multi-frequency tone, waking up a preset function of the smart device based on the multi-frequency tone. A device for waking up a smart device as well as a smart device incorporating the device includes processing elements for performing the method. A non-transitory computer-readable storage medium stores computer instructions to cause processing elements to perform the method for waking up a smart device.

Method and apparatus for waking up smart device, smart device and medium

An ultrasonic data transmission method, apparatus and system, a terminal device and a medium are provided. The method is applied to a transmitting terminal which includes at least two ultrasonic signal transmitting arrays. The method includes: a single-frequency ultrasonic coding signal of to-be-transmitted information corresponding to each ultrasonic signal transmitting array is respectively determined, ultrasonic codes of to-be-transmitted information corresponding to different ultrasonic signal transmitting arrays being different; and corresponding at least two single-frequency ultrasonic code signals are transmitted through the at least two ultrasonic signal transmitting arrays to a receiving terminal in a focusing mode, frequency bands of transmitting frequencies of different ultrasonic signal transmitting arrays being different.

Ultrasonic data transmission method, apparatus and system, terminal device and medium

A frequency combination corresponding to target data to be transmitted is determined. The frequency combination includes at least two different frequencies. Ultrasonic waves of frequencies in the frequency combination are sent within a predetermined duration.

Method and device for processing ultrasonic waves

The present invention discloses a floating gate structure of a flash memory device and a method for fabricating the same, which relates to a nonvolatile memory in a manufacturing technology of an ultra-large-scaled integrated circuit. In the invention, by modifying a manufacturing of a floating gate in the a standard process for the flash memory, that is, by adding three steps of deposition, two steps of etching and one step of CMP, an-shaped floating gate is formed. In addition to these steps, all the other steps are the same as those of the standard process for the flash memory process. By the invention, a coupling ratio may be improved effectively and a crosstalk between adjacent devices may be lowered, without adding additional photomasks and barely increasing a process complexity, which are very important to improve programming speed and reliability.
