Abstract: A device includes a case having a case sidewall defining a circular receiver having a receiving opening and a central axis. A device body, which is waterproof in one or more applications, includes a sidewall defining a receiving aperture. A crown stem includes a push button disposed within a duct of a threaded bushing and one or more O-rings disposed about the actuation stem to allow translation of the actuation stem in the duct while preventing liquids from passing through the duct. The crown stem inserts through the aperture in the case so that the threaded bushing can hermetically seal the receiving aperture when the device body is inserted into the circular receiver to prevent the liquids from entering the receiving aperture.

Abstract: A wearable apparatus can include a transceiver. The apparatus can include an electrically conductive housing, the transceiver carried in the housing, the housing including at least a first wearable apparatus carrier device connection area. The apparatus can include a radiating element, the radiating element connected to the housing, the radiating element coupled to a feed point that is coupled to the transceiver, and the radiating element configured to radiate radio frequency signals. The apparatus can include a current isolation element. The apparatus can include an electrically conductive wearable apparatus carrier device coupled to the electrically conductive housing via the current isolation element, where the current isolation element provides electrical isolation between the electrically conductive wearable apparatus carrier device and the electrically conductive housing and/or the radiating element.

Abstract: A device includes a case comprising a case sidewall defining a circular receiver having a receiving opening and a central axis. An inner wall of the case defines one or more engagement members. A device body includes a sidewall defining a receiving aperture. The device body inserts into the circular receiver along the central axis at a first rotational alignment. A bezel is coupled to the device body, and couples to the case at the receiving opening. The bezel includes an annular engagement ring defining one or more complementary engagement features to engage the one or more engagement members. A crown stem serves as an axial retention device to retain the device body in the second rotational alignment.

Abstract: Disclosed are removable “locking pins” that hold the front and rear housings of a wearable device together. These pins fit into receiving channels in the walls of the housings. Unlike screws or other fasteners, these pins do not take up space needed for internal components of the device. Unlike snaps, the pins are usable with housings that are very rigid (e.g., metal or ceramic). In some embodiments, the pins are entirely hidden from view, and thus they do not detract from the appearance of the device. Also in some embodiments, the pins fit entirely outside of a water seal for the device, thus reducing cost and assembly complexity.

Abstract: An apparatus can include a wrist worn device configured to be worn on a wrist of a user. The apparatus can include a controller. The apparatus can include a power supply. The apparatus can include a light emitter that can emit light from a user side of the wrist worn device to a wrist of the user. The apparatus can include a light detector that can detect light reflected from the wrist of the user from the first light emitter and can send a detector signal to the controller. The detector signal can be based on the detected light. The apparatus can include a lens coupled to a user side of the wrist worn device external to the light emitter and light detector. The lens can include an opaque section. The lens can also include light transmissive section that transmits light from the light emitter to the user.
