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.

Functional jewelry is disclosed. A bracelet includes a plurality of light-emitting diodes (LEDs), a main control unit, and positional and situational sensors, typically including an accelerometer, as well as a decorative, interchangeable fascial layer. The bracelet may also include sensors such as capacitive touch sensors, a microphone, and a color sensor. A radio transceiver within the bracelet is adapted to implement a protocol such as BLUETOOTH 4.0, and is adapted to allow the bracelet to communicate in peer-to-peer or master-slave mode. Two users can pair their bracelets in person, usually with a gestural trigger, for shared light displays, multi-player games, and other types of interactions. Larger groups can pair temporarily and contextually for multi-user displays and interactions, in an ad hoc network with distributed functions. Real-world interactions are communicated to a social network with profiles linked to the individual bracelets.

An illuminated ankle strap assembly for enhancing visibility of a user in a darkened environment includes a strap that is wearable around a user's ankle. A plurality of light emitters is coupled to the strap to emit light outwardly from the strap. Each of the light emitters is actuatable in a first condition having each of the light emitters blinking on and off to visually alert the motorists to the location of the user in a darkened environment. Each of the light emitters is actuatable in a second condition has each of the light emitters is continually on. In this way each of the light emitters enhances visibility for the user when the user is walking in a darkened environment.

An artificial jewel with internal light source may be configured for removable attachment to a region of human skin. The artificial jewel with internal light source may be assembled from a shell, a base-plate, and an electronics-assembly. A portion of the electronics-assembly may be disposed between an inside surface of the shell and an inside surface of the base-plate. The electronics-assembly may include at least one light source that may reside between the shell and the base-plate. The electronics-assembly may include a push button that may extend out beyond a bottom of the base-plate. A bottom of the base-plate may have a sticky adhesive layer for removable attachment to the region of human skin. An exterior surface of the shell may be faceted. The shell may be optically transparent. A distal portion of the push button may physically touch the region of human skin.

An electronic wearable device is disclosed. The electronic wearable device includes a pendant attached to a necklace; the pendant comprising a base and a plurality of interchangeable faceplates; wherein each of the plurality of interchangeable faceplates has a different design and is configured to attach to the base to hide the base.

A compact precision illumination source mounts on a finger of a user for providing localized illumination for precision tasks such as surgical procedures and other tasks performed in dark or confined spaces. A frame having a circular or arcuate shape engages the finger, and secures an enclosure having a small but powerful bright, light focused on a predetermined region defined by the end of the digit that is likely the activity region for an instrument grasped by the digit.

An illuminated ankle strap assembly for enhancing visibility of a user in a darkened environment includes a strap that is wearable around a user's ankle. A plurality of light emitters is coupled to the strap to emit light outwardly from the strap. Each of the light emitters is actuatable in a first condition having each of the light emitters blinking on and off to visually alert the motorists to the location of the user in a darkened environment. Each of the light emitters is actuatable in a second condition has each of the light emitters is continually on. In this way each of the light emitters enhances visibility for the user when the user is walking in a darkened environment.

Article of jewelry includes a main frame defining a cutout in a medial portion thereof, a magnifying glass received within the cutout, and a light source configured to disperse light proximal to the magnifying glass. The main frame comprises a first configuration where the main frame is pivoted inwardly to form a bracelet orientation, and a second configuration in which the main frame is pivoted outwardly to form a magnifying orientation.

A light-emitting jewelry piece includes a gemstone, a head, and a mounting. The head is configured to interconnect the gemstone to the mounting. The mounting is arranged secure the light-emitting jewelry piece to a person or a personal adornment.

An illuminated accessory. The illuminated accessory includes a housing that may be elastic, a power source inside the housing, electric lights connected to the power source, and a power switch to control the electric lights and/or other components of the illuminated accessory, such as a camera, a microphone, a clock, and/or a timer. The illuminated accessory may be configured to wrap around a wrist of an individual and worn as a bracelet, and/or may be configured to wrap around a device, such as a hair trimmer, and used as a light source when performing an activity, such as trimming hair.
