A wrist-worn device is provided, which includes a device main body and an earphone. An accommodating groove for placing the earphone is provided on the device main body, a key is slidably mounted on one of the device main body and fee earphone. A clamping groove is provided on the other one of the device main body and the earphone, and a snapin head cooperating with the clamping groove is provided at a top of the key. The key is provided with a first attraction portion, the device main body or the earphone having the clamping groove is provided with a second attraction portion, and the first attraction portion is magnetically attracted with the second attraction portion in a case that the key slides forward until the snapin head is inserted into the clamping groove.

A band for securing an electronic device to a user may include a monolithic band body having proximal and distal ends for coupling to a body of the electronic device. The monolithic band body may include an elastic material that is elastically stretchable between (1) a fitted mode where the electronic device is secured to a limb of the user, and (2) a stretched mode for fitting over the limb of the user.

An adaptive assisted grip apparatus includes a holder comprising an elongated piece of resilient, compressible material; and an insertion channel extending at least partially into the holder parallel to the length of the holder, wherein the insertion channel is configured to expand and contract to accommodate both the size and the shape of the inserted cosmetics product to thereby grip and retain the cosmetics product at least partially inserted within the insertion channel; wherein the holder is configured to be held in the hand of a user such that the cosmetics product can be held and used by the user holding the holder.

Methods, systems, and devices for wireless communications are described that provide for managing transmissions using multiple component carriers (CCs) in which transmissions using one or more of the CCs may span less than a full transmission time of a slot or other transmission time interval. A UE may signal a capability to transmit such transmissions, and one or more capabilities related to carrier aggregation that may be used by a base station for scheduling of transmissions on different CCs. In the event that overlapping transmissions on two or more CCs exceed a maximum power threshold, various techniques for dropping at least a portion of one or more transmissions of one or more CCs are described.

It is herein disclosed a novel strap for a wearable electronic device and a wearable electronic device with such a strap. The strap features a first layer of microfiber and a second layer of natural or artificial leather as an outer layer. A layer of elastic adhesive attaches the first layer to the second layer.

A wearable contact tracing wristband has a main body with at an indicator light, a location tracker, and a processor. The indicator light provides a visual indication, such as a red light, of when the user is exposed to the condition and until testing or clearance occurs. A wireless communication module is connected to the processor, for remote and automatic activation of the indicator light.

A Brunnian link is a link formed from a closed loop doubled over itself to capture another closed loop to form a chain. The example kit provides for the successful creation of unique wearable articles using Brunnian link assembly techniques and includes several pin bars that are supported in a desired special orientation by at least one base. The desired special orientation is dependent on the desired linked configuration of the completed article. The pins may be assembled in various combination and orientations to provide endless variation of completed link orientations.
