Abstract: Provided is a method for delaying signals. The method includes: determining a total quantity of delay phases by which a drive signal is to be delayed; determining, based on a clock period of each level of delay clock signals of a plurality of levels of delay clock signals, a quantity of clock periods of each level of delay clock signals that are required for delaying by the total quantity of delay phases, wherein the clock periods of the levels of delay clock signals decrease sequentially from a first level to a last level; and delaying the drive signal by the quantities of clock periods of the levels of delay clock signals sequentially in descending order, and outputting the drive signal after delay.

Abstract: Provided are an ultrasonic imaging method and device, and a storage medium. The ultrasonic imaging method includes: acquiring an ultrasonic echo signal; segmenting the ultrasonic echo signal into a first predetermined number of sub-echo signals according to scan depths; performing amplitude apodization on each sub-echo signal with a predetermined window function to obtain processed sub-echo signals; completing ultrasonic imaging according to the processed sub-echo signals. At least one sub-echo signal is subjected to the follow processing: segmenting the at least one sub-echo signal into a second predetermined number of unit echo signals according to the scan depths, and assigning a weighting coefficient to each unit echo signal; performing amplitude apodization on each unit echo signal with the corresponding predetermined window function, and weighting the unit echo signals with corresponding weighting coefficients to obtain processed unit echo signals; and forming a processed sub-echo signal from the processed unit echo signals.

Abstract: An electronic apparatus is provided. The electronic apparatus includes a touch control device configured to detect a touch; a processor configured to classify the touch into one of at least two modes; a haptic device configured to produce a haptic action accompanying an individual touch action; and a driving circuit configured to drive the haptic device. The processor is configured to, upon determination that the touch is of a first mode, transmit a first driving signal to the driving circuit. The driving circuit is configured to, upon receiving the first driving signal, drive the haptic device to produce a plurality of sub-actions cumulatively achieving at least a part of the haptic action accompanying the individual touch action. At least two sub-actions of the plurality of sub-actions are different from each other in at least one parameter.
