Smart watches and associated systems and methods thereof for lock-screen management are disclosed. A smart watch includes a heart rate sensor, and a method for lock-screen management of the smart watch includes: reading, by the heart rate sensor, a heart rate; determining based on the heart rate whether the smart watch has been taken off by the user, and if yes, stopping the heart rate sensor from working and entering by the smart watch a password-lock-screen mode. Thus, using the method according to the present disclosure can improve the information security on the smart watch.

A wristwatch includes a main unit, a first design belt detachably attached to the main unit, an identifier that identifies the first design belt, a display device that displays the display content, a memory that stores the display content displayed on the display device, and a display control unit that displays the display content corresponding to the first design belt identified by the identifier on the display device.

A wearable apparatus, comprising: a mounting component (2), configured to hold a relationship between relative positions of the wearable apparatus and its user; a folding panel (1) mounted on the mounting component (2), the folding panel (1) including at least two display screens (11,12,13,14) interconnected at a joint where sensors are disposed; and a controller (60) signal connected with individual display screens (11,12,13,14) and the sensors (50) respectively, the controller (60) being configured to control corresponding display screens to turn on or turn off based on the state of the folding panel (1) detected by the sensors (50). The state of the folding panel in the wearable apparatus can be adjusted according to the needs of a user and thereby the usage needs of the user can be satisfied.

Provided are a display method and apparatus, a smart wearable device, and a computer-readable storage medium, the display method being used on the smart wearable device, and the smart wearable device including at least two screen display regions and at least two corresponding audio collection units; when a user is wearing the smart wearable device, the screen display regions are not simultaneously in the same plane. The display method includes according to voice signals collected by all of the audio collection units, determining an audio collection unit nearest a sound source; turning on a screen display region corresponding to the audio collection unit nearest the sound source to display current content.

Display units for digital out of home advertising with orientation-based operations adjustment and related methods are provided. The display unit includes an electronic display. A controller for the display unit receives orientation data from an orientation detection device, determines an orientation of the display unit, and adjusts operations of the display unit based, at least in part, on the orientation.

An electronic device, such as a watch, has a housing to which a carrier is attached. The carrier has a first surface interior to the electronic device, and a second surface exterior to the electronic device. A set of electrodes is deposited on the exterior surface of the carrier. An additional electrode is operable to be contacted by a finger of a user of the electronic device while the first electrode is positioned against skin of the user. The additional electrode may be positioned on a user-rotatable crown of the electronic device, on a button of the electronic device, or on another surface of the housing of the electronic device. A processor of the electronic device is operable to determine a biological parameter of the user based on voltages at the electrodes. The biological parameter may be an electrocardiogram.

A liquid crystal control circuit includes: a first terminal that outputs a rewriting signal for rewriting a plurality of pixels; a second terminal that periodically designates a start timing of the rewriting signal; a third terminal that outputs a polarity signal for designating polarity of AC voltage; a first circuit that identifies a next second inversion timing of any first inversion timing at which the polarity is inverted; a calculator that calculates a first start timing after the first inversion timing based on the start timing; a second circuit that determines whether the second inversion timing is within a period from a predetermined time before the first start timing to the first start timing; and an inversion unit that inverts polarity of the polarity signal after the rewriting signal starting from the first start timing is stopped, when the second inversion timing is within the period.

A watch includes a pointer that rotates and indicates a time, a notifier that performs a notification operation to a user in a mode other than a visual mode, and a processor that controls the rotation of the pointer and the notification operation of the notifier. The processor is configured to control the pointer to cause the pointer to rotate faster than a rotation corresponding to a passage of time and move to a specified position and, when the pointer arrives at a notification position while the pointer is moving fast, control the notifier to cause the notifier to perform the notification operation.

There is provided an information processing apparatus that can appropriately present information to the user, and reduce power consumption, the information processing apparatus including: a display control unit configured to display, on a display unit, display information to which an expiration date is set, on a basis of a display instruction; and a processing control unit configured to control executability of predetermined processing on a basis of whether or not the expiration date has passed.

A device for measuring the concentration of a gas constituting the ambient air includes a wristwatch comprising a watch case (13) containing a watch movement, members indicating the time (1, 3, 9) visible through a glass of the watch case (13). In addition, the wristwatch comprises at least one sensor (11) arranged to measure the concentration of a gas constituting the ambient air. The wristwatch also includes means for actuating an alert when reaching or exceeding a threshold of the gas concentration measured by the sensor (11). The device includes two operating states, a “time” state and an “alarm” state, wherein in the “time” state, the members indicating the time (1, 1′, 3, 9) indicate the time and the sensor (11) permanently measures the gas concentration without displaying it or activating the alert. In case where the sensor (11) detects a concentration of a gas, the device switches to the “alert” state wherein the indicator member (4, 4′, 8, 9, 10) displays this measured value and/or the means for actuating an alert actuate an alert normally without the time being displayed.
