A wearable electronic simulated smoking device is provided for delivery of a desired active ingredient responsive to a user's inhalation through the device. The device includes an elongated tubular member having at least one fixedly arcuate shaped portion to at least partially encompass a portion of a user's body and is releasably retainable thereat. The device includes a vaporization chamber supplied with a vaporizable smoking composition and enabled by a controller to generate vapor from the vaporizable smoking composition and add the vapor to air drawn through the device.

A ring type antenna module and a jig for manufacture for manufacturing the same, which can communicate regardless of the orientation when mounted on a ring type wearable device and can easily process the size are provided. The ring type antenna module includes a base substrate having flexibility on which a radiation pattern is formed, a terminal part formed on one end of the base substrate and connected to one end of the radiation pattern, and the other terminal part formed on the other end of the base substrate and connected to the other end of the radiation pattern; and the size of the ring type antenna module is adjusted by varying the coupled location between the terminal part and the other terminal part.

A personal jewelry article includes a light source coupled to a power source and located within a compartment interior of a shank of the personal jewelry article. A stone is connected to the shank above the compartment. The light source emits light through the stone and the stone alters the light emitted by the light source.

A ring-type wearable device is disclosed. The disclosed ring-type wearable device comprises: an outer ring member; an inner ring member separably inserted into the outer ring member; a sensor unit disposed in the outer ring member; and a control unit disposed in the outer ring member so as to be electrically connected to the sensor unit, wherein the sensor unit can maintain constant sensitivity in correspondence to the thickness of the inner ring member.

Embodiments of the present invention disclose a self-defense ring assembly and method for a user to deter an assailant, having a ring body, a chamber within the ring body containing a pressurized repellant, a conduit within the ring body, a nozzle located on a surface of the ring body, and a button located on the ring, the button having a portion of the conduit passing through the button such that the button selectively translates the portion of the conduit. Furthermore, the ring assembly includes a track running along the ring body, and a cover member that selectively translates along the track, the cover member selectively exposing the button.

A smart ring includes a body including flexible material, a first part, a second part removably connected to the first part, and at least one pair of break-away portions disposed within the body separate from the first part and the second part. One or more of a battery, a charging unit, a processor unit, a user input unit, a communication unit, a memory unit, at least one sensor unit, an output unit or a user input unit is disposed in or on one of the first part and the second part. Each of the break-away portions of the pair of break-away portions is removable from the other break-away portion upon movement of one break-away portion in a direction away from the other break-away portion.

A jewelry head for mounting a precious or semi-precious gem to an article of jewelry, the jewelry head having a ferrimagnetic body with an inner cavity configured to accept a precious or semi-precious gem; and a near field communication circuit having a near field communication chip electrically connected to an antenna, where the antenna is wrapped around and against the ferrimagnetic body.

Systems and devices for a ring wearable cover with non-deformable circumference are described. The removable cover for a wearable ring device may include a ring-shaped surface configured to extend around a full circumference of the wearable ring device when the removable cover is in a mounted state on the wearable ring device and one or more mounting features that are disposed on the ring-shaped surface. The one or more mounting features may be configured to interact with a surface of the wearable ring device to lock the removable cover onto the wearable ring device when the removable cover is in the mounted state on the wearable ring device. In some cases, a diameter of the removable cover is unchanged while the removable cover transitions from the mounted state on the wearable ring device to an unmounted state off of the wearable ring device.

Methods, systems, and devices for a functional cover are described. A removable cover (e.g., a functional cover) for a wearable ring device (e.g., a ring wearable) may include one or more electrical components positioned at least partially within the removable cover. The removable cover may further include a first electrical component exposed to an external surface of the removable cover, the first electrical component configured to contact (e.g., physical and electrically contact) a second electrical component of the wearable ring device, such as when the removable cover is in a mounted state on the wearable ring device. The first electrical component may be further configured to transfer electrical current, data, or both, between the one or more electrical components of the removable cover and one or more additional electrical components of the wearable ring device.

An identification system includes a mobile computing device having a memory and an establishing module establishing an identifying data set stored in the memory. The identifying data set includes an accumulated data gathered at the mobile computing device over an establishing period and is capable of uniquely identifying a user corresponding to the mobile computing device.
