An electronic watch may include a housing defining a side wall having a through-hole and a crown assembly including an actuation member. The actuation member may include a crown shaft extending through the through-hole and having an exterior portion defining an input surface and a crown ring coupled to the exterior portion of the crown shaft and electrically isolated from the crown shaft. The crown assembly may further include an optical encoder component attached to the actuation member and defining a group of optical features. The electronic watch may further include an optical detector configured to detect rotation of the crown assembly by detecting motion of the group of optical features and an electrocardiograph sensor comprising a sensing component. The sensing component may be conductively coupled to the actuation member via a conductive path at least partially defined by the crown shaft.

An electronic device, such as a watch, has an input mechanism, such as a crown, that may receive translational inputs, rotational inputs, and/or touch inputs. Inputs received at the crown may result in changes in operation of the electronic device and/or outputs, such as graphical outputs, provided by the electronic device. In various embodiments, the crown includes a retainer that couples an outer crown body to an inner crown body and secures an isolator between the outer crown body and the inner crown body. The embodiments of the crown described herein provide a simple and robust input mechanism for receiving rotational, translational, and touch inputs as described above, while simplifying part alignment, ensuring consistent rotation, and allowing for efficient manufacturing.

An electronic device, such as a watch, has a crown assembly having a shaft and a user-rotatable crown. The user-rotatable crown may include a conductive cap that is mechanically and electrically coupled to the shaft and functions as an electrode. The conductive cap may be coupled to the shaft using solder or another conductive attachment mechanism. The shaft may electrically couple the conductive cap to a processing unit of the electronic device. One or more additional electrodes may be positioned on the exterior surface of the electronic device. The conductive cap is operable to be contacted by a finger of a user of the electronic device while another electrode is positioned against skin of the user. The processing unit of the electronic device is operable to determine a biological parameter, such as an electrocardiogram, of the user based on voltages at the electrodes.

Embodiments of the present invention disclose a display screen control method and apparatus, and a terminal. The method in the embodiments of the present invention includes obtaining a height difference and an acceleration that are generated when a terminal moves from an initial position to a target position and determining, according to the height difference and the acceleration, whether a first predetermined movement is satisfied. The method also includes when the first predetermined movement is satisfied, triggering the terminal to turn on a display screen.

The present disclosure generally relates to interacting with an electronic device without touching a display screen or other physical input mechanisms. In some examples, the electronic device performs an operation in response to a positioning of a user's hand and/or an orientation of the electronic device.

An electronic watch includes a housing defining a side surface of the electronic watch, a transparent cover coupled to the housing and defining a front surface of the electronic watch, an image-sensing element, and a crown extending from the side of the housing and defining an imaging surface. The crown may include a light-directing feature configured to direct, onto the image-sensing element, an image of an object in contact with the imaging surface.

A compact crown for an electronic device such as an electronic watch, including a set of wipers capable of determining a rotation angle, rotation direction, or rotation speed, is disclosed. The set of wipers is in contact with at least one resistance member at different angular positions around a rotation axis. The crown may have a group of ground taps disposed along the resistance member and a measured signal may vary based on the position of each wiper as it contacts the at least one resistance member. A compact crown may also include capacitive members and capacitive sensors in order to similarly determine rotation angle, rotation direction, or rotation speed.

A timepiece illusion device is formed to appear as an ordinary analog watch or timepiece with hour and minute hands. A software application (Illusion App) is provided that can be loaded onto a smartphone or other device. The Illusion App allows a user to provide inputs into the smartphone, which are transmitted (e.g., as time commands, etc.) from the smartphone to the timepiece illusion device. The timepiece illusion device then moves the hour and minute hands per the time command or otherwise performs the relevant operation per the input from the smartphone.

A switch module for an electronic device detects translational inputs and defines at least portion of a conductive path from an input surface of the electronic device to a processing unit of the electronic device. The switch module may be a component of a crown assembly for detecting rotational inputs, translational inputs, touch inputs and/or biological signals such as electrocardiogram (ECG) signals. The switch module may include a conductive dome and a friction guard that is positioned between the conductive dome and the actuation member of the crown assembly. The conductive dome and/or the friction guard may define at least a portion of the conductive path from the input surface to the processing unit.
