Wearable devices having a primary and secondary power source are disclosed, wherein the secondary power sources are located in links of a band portion of the wearable device and the secondary power sources provide a secondary source of power beyond that provided by the primary power source. One exemplary wrist-wearable device includes a centralized processor pod having a primary power source, a wireless communication radio, and one or more sensors. The exemplary wrist-wearable device further includes a band with a plurality of links. Each of the plurality of links can include a secondary power source. The exemplary wrist-wearable device further includes communicative pathways that can be configured to convey at least power and data between the links and centralized processor pod. The communicative pathways can be configured to convey power from the secondary sources of power to the centralized processor pod beyond the power provided by the primary power source.

An electronic device includes a non-rectangular display, an information acquisition sensor, and a processor. The processor allocates information acquired from the information acquisition sensor to any of a plurality of display regions having different sizes or shapes within a display range. The information is displayed on the display in a different display mode depending on whether the information is allocated to a first display region or to a separate display region out of the plurality of display regions.

A wearable device is used to authenticate a user into a user account at a user device of the user. In particular, the wearable device may include a sensor configured to detect whether the wearable device is worn by or is with the user. If so, the wearable device may send a signal to the user device and the user device may authenticate the user based on the signal received from the wearable device. For example, when the sensor detects that the wearable device is worn by the user, the wearable device may send a unique signal periodically, such as every five seconds or every 10 seconds. Based on whether the unique signal from the wearable device is received, the user device may authenticate the user.

A system for transforming a regular smartwatch into a luxury item, comprising, a smartwatch unit including at least the display unit of the smartwatch; and a box including a housing to accommodate said smartwatch, said box having a cover being openable and closeable to cover said display unit, wherein said cover has at least one hole so that a corresponding portion of said display unit is visible to a user when said cover is in closed position, wherein when said cover is in closed position, the smartwatch unit displays the output of the smartwatch in on said corresponding portion of the display.
