A multipurpose accessory and storage system for an electronic device includes a housing member attaching to the electronic device and a charging station structured on the housing member to charge, arrest and dispense an accessory item. The accessory item includes a protective membrane housing a logic board, a power component, an image sensor, a transmitter configured to transfer a signal or data to the electronic device or the housing member and a software program stored in the logic board. The transmitter establishes a pairing or electronic connection between the electronic device or the housing member and the accessory item. The pairing or electronic connection enables content captured by the image sensor to be relayed to the electronic device to permit a user to view the content on the display of the electronic device and/or to control components and features of the accessory item via the electronic device.

Provided is a wearable device for displaying translucent stones and the like. The wearable device comprises a base, a back plate, a bezel and a locking element. The base comprises a cavity, at least one base locking element a recess comprising a recess void and an illumination assembly in the cavity wherein the illumination assembly comprises an illuminator capable of emitting light. The back plate is reversibly mountable on the base. The back plate comprises at least one back plate locking element. The back plate locking element is reversibly engageable with the base plate locking element. A tab is provided on the back plate which is receivable by the recess. The tab comprises a tab void which is alignable with the recess void. An illumination window in the back plate allows light to transmit through said illumination window. The back plate also comprises at least one securing recess and a paint preferably in an engraving. The bezel is reversibly mountable on the back plate. The bezel comprises a viewing window and a securing tab wherein the securing tab is received by the securing recess. A locking element extends through the aligned tab void and recess void.

Systems and methods for evaluating gemstones are disclosed. The system includes a gemstone holding case, an illumination pad and an image capturing and gemstone evaluation device. The case includes a transparent viewing window in a top wall, a translucent bottom wall and a compressible light-diffusing pad for receiving gemstones thereon. The case and pad are dimensioned such that, when closed, the viewing window presses the gemstones into the pad holding them in place and level and allowing for in situ gem imaging. The illumination pad includes embedded LEDs for selectively illuminating the portion of the pad on which the case is placed. The controllable lighting, translucent case and diffusive pad serves to evenly light the gems and reduce unwanted light thereby improving the images and analysis performed using the image capturing and gemstone evaluation device. Methods for analyzing gemstones under diffuse lighting using the system is also disclosed.

A case for an eyewear device includes a body defining an opening leading to a storage chamber that is sized for retaining the eyewear device. A cover depends from the body and is movable between an open position, in which the opening is exposed, and a closed position, in which the opening is covered by the cover. A battery is mounted to the body for charging the eyewear device. A detector is positioned on either the body or the cover for detecting when the cover is in the open position or the closed position. A display displays a charge state of the battery when the cover is in the open position.

An axle-free wheel comprising: an outer rim member having a ground interface on an external surface thereof and an outer ball race or rolling race on an inner surface thereof; an inner rim member having an inner ball or rolling race on an outer surface thereof.

A flexible frame element has a receiving curved surface which is concave to mate with and receive the curved surface of an object upon which it is to be applied. The frame element is substantially transparent and includes a phosphorescent layer along the concave curved surface. The frame element may include a flexible wire to provide structural integrity. The frame element is disposed along the phone body with the concave surface receiving the convex surface and the phosphorescent layer being disposed between the convex surface of the phone body and the concave surface of the frame element.

A protective smartphone case with UV LED sanitizer configured for attachment to a smartphone includes a plastic smartphone case body having a base, a top end, and a bottom end with four impact resistant sides which form the perimeter of the said smartphone case body; a back cover plate; a fixed bracket; a power connector; a touch switch module; a phone power socket; and an LED ultraviolet light module. Use of the protective smartphone case with UV LED sanitizer includes the steps of attaching a smartphone to the plastic smartphone case body, pointing the LED ultraviolet light module in the direction of the surface or object to be disinfected, positioning the LED ultraviolet light module at an optimal distance from the surface or object, engaging the touch switch module, irradiating the surface or object for a recommended period of time and disengaging the touch switch module.
