Certain embodiments include an apparatus, system, or method for time-gain compensation control of an ultrasound system. A computer-implemented method can include providing a tactile gain control comprising a near, middle, and far gain control. The middle gain control can be configured for two-dimensional range adjustment of depth and gain. The computer-implemented method can also include adjust at least one of the near, middle, or far gain control. In addition, the computer-implemented method can include displaying an ultrasound image based on at least one of the adjusted near, middle, or far gain control.

A screenshot image sharing method, a terminal and a storage medium are provided. The method includes: when a screenshot instruction is received, performing screenshot processing on a first user interface to obtain a screenshot image; displaying a floating window on an upper layer of the first user interface; displaying a second user interface in response to a first operation signal for triggering display of the second user interface; and sharing, in response to a second operation signal acting on the floating window, the screenshot image to a target object corresponding to the second user interface. According to the screenshot image sharing method, the operation required for sharing the screenshot image to other objects can be reduced, and the image sharing efficiency is improved.

A verification method, includes: in a case that the first operation does not meet a verification condition, adjusting a current value of a first sub-region in the verification region, or increasing an area of the first sub-region in the verification region, or adjusting a current value of a second sub-region in the verification region. The verification region includes the first sub-region and the second sub-region, and after the current value of the first sub-region or the current value of the second sub-region is adjusted, the current value of the first sub-region is greater than the current value of the second sub-region.

An electronic device is provided. The electronic device includes a display, a memory storing executable instructions, and at least one processor, wherein, when the instructions stored in the memory are executed, the at least one processor is configured to, the occurrence of an event for generating a folder including at least one icon corresponding to at least one application; control the display to display a folder screen including the at least one icon; control the display to display at least two folder names corresponding to the at least one application, receive a user input for selecting a first folder name from among the displayed at least two folder names, and control the display to display the selected first folder name as the folder name of the folder on the folder screen.

Technologies are disclosed for providing visual feedback during touch-based operations on user interface (“UI”) elements. Through implementations of the disclosed technologies, visual feedback can be provided to users during certain touch-based operations on UI elements presented by touch-enabled computing devices. The visual feedback can provide confirmation to users that certain touch-based operations on UI elements were performed successfully. The visual feedback provided by the disclosed technologies can make it easier for users to select a UI element, to understand that actions taken to select a UI element were successful, and to successfully perform operations on UI elements once they have been selected. These benefits can reduce the number of times users need to attempt certain touch-based operations on UI elements. This, in turn, can reduce the utilization of computing resources, such as memory and processor cycles, by touch-enabled computing devices implementing the disclosed technologies.

A capacitive touch screen display operates by: providing a display configured to render frames of data into visible images; providing a plurality of electrodes integrated into the display to facilitate touch sense functionality based on electrode signals having a drive signal component and a receive signal component; generating, via a plurality of drive-sense circuits coupled to at least some of the plurality of electrodes, a plurality of sensed signals; receiving the plurality of sensed signals; generating a stream of capacitance image data associated with the plurality of cross points that includes capacitance variation data corresponding to variations of the capacitance image data from a nominal value within a temporal period; and processing the capacitance image data to determine a touchless gesture occurring within the temporal period.

Systems and methods are described that include providing, on a touchscreen display of an electronic device, a stream of content items, at least some of which are associated with a corresponding display anchor. Inputs are detected at the touchscreen display and the inputs are associated with a scroll speed. The scroll speed may be based on a detected distance between the inputs on the touchscreen and an elapsed time between at least two of the inputs. In response to determining a lack of input for a predefined time period, a display anchor can be determined and selected. The display anchor may correspond to a content item to be used as a pause location for the stream. The scrolling of the stream of content items can be paused at the pause location to use the selected display anchor to display the content item in a top viewable portion of the display.

A method for processing a touch instruction, an electronic device and a storage medium, related to the fields of Internet of Things, intelligent transportation, and the like, are provided. The method includes: detecting a type of a received touch event; in a case where the type of the touch event is a predetermined type, acquiring a number of fingers which execute the touch event of the predetermined type each time; and determining a touch instruction by utilizing a change situation of the number of fingers which execute two adjacent touch events of the predetermined type. According to the solution, the number of fingers which execute the touch event can be determined by utilizing the change situation of the number of fingers corresponding to two adjacent touch events conforming to the predetermined type.

Systems are disclosed for navigating a marine vessel with a navigation system that displays a planned route including a set of current and future waypoints. The system has a display and an integrated user input control. A new desired current heading and new future waypoints with associated future headings are provided and a corresponding autopilot navigates accordingly.

A device and method for controlling the audio level of a device are provided. The device includes a housing, a roll unit mounted such that it is able to rotate in the housing, a flexible, touch-sensitive display configured to be rolled on the roll unit around a roll axis so that a first, curved portion of the display forms a side screen bent around the roll unit, and a second, planar portion of the display forms a front screen, wherein the area of the front screen changes according to a rotation of the roll unit, and a controller configured to adjust, in response to detecting a predefined multi-touch gesture on the side screen, an audio output volume of the device.
