A smart ring charging system comprises a charging source integrated into an object, the object configured to be held by a user wearing a smart ring. The smart ring may include a ring-shaped housing and a power source disposed within or at the ring-shaped housing and configured to receive energy from the charging source while the user is wearing the smart ring and holding the object. A controller may be disposed within or at the ring-shaped housing, or at the object with the charger and configured to estimate a charging rate at which the power source receives the energy from the charging source. The system may further include one or more indicators configured to indicate the charging rate.

Described is a toy figure with activated components that are activated by wearable accessories. For example, a wearable ring can be positioned onto a toy figure as a mask or helmet, such that upon positioning the wearable ring upon the toy figure, the toy figure is activated to perform a function. The function is an action, such as causing the toy figure to reveal or expose a toy weapon (e.g., sword, gun, etc.), thereby allowing a user to engage in a variety of game play.

A smart ring is configured harvest mechanical energy using piezoelectricity. The smart ring includes a ring-shaped housing, a power source disposed within the ring-shaped housing, and a charging circuit. The charging circuit includes a piezoelectric harvesting element, and is configured to charge the power source when user motion causes a mechanical deformation in the piezoelectric harvesting element. The smart ring further includes a component, disposed within the ring-shaped housing and configured to draw energy from the power source, and further configured to perform at least one of: i) sense a physical phenomenon external to the ring-shaped housing, ii) send communication signals to a communication device external to the ring-shaped housing, or iii) implement a user interface.

The finger ring is convenient to assemble, increasing the assembly efficiency and reducing the production cost, can protect the blade, and is convenient to carry.

A ring-shaped earphone may be configured to be worn in an ear. When not worn in the ear, the ring-shaped earphone may be conveniently stored on a finger. In one example, the ring-shaped earphone may include a ring-shaped body defined by an outer cylindrical surface and an inner cylindrical surface. The earphone may include a speaker within the ring-shaped body. The speaker may be configured to project sound through a speaker opening in the outer cylindrical surface. The earphone may include a microphone within the housing. The microphone may be configured to receive sound through a microphone opening in the inner cylindrical surface.

A method includes the selection of a jewelry blank having a chamber for receiving a gem. The chamber is partially filled with a first layer of UV resin. Cremation remains are placed within the first layer of resin or on the surface of the first layer of resin. Then, UV light is used to cure the first layer of resin. A second layer of resin partially fills the remaining void and is cured. Diamond dust may be added to the top surface of the cured second layer. A final layer of protective resin is added into the remaining space of the chamber and cured to create the finished jewelry piece.

A jewelry apparatus can include a base member having a hippocrepiform configuration, the base member having a first prong and a second prong. The jewelry apparatus can include a coupling member operably configured for attachment to the base member. The coupling member can include a disk member having a first side and a second side, the first side having a first set of indicia depicting a first partial portion of a word, the second side having a second set of indicia depicting a second partial portion of the word, a first projection extending from the disk member operably configured for attachment to the first prong and a second projection extending from the disk member operably configured for attachment to the second prong. The first projection or the second projection is configured to produce a tactile indication when inserted into or removed from the first prong or the second prong.

A ring comprising: an inner surface; an outer surface; and a central axis; the inner surface and the outer surface are connected by an upper surface and a lower surface; the central axis is orthogonal to the ring; the inner surface comprises an inner top portion, inner narrow portion, and inner bottom portion; the inner top portion of the inner surface comprises an inner top circumference; the inner narrow portion of the inner surface comprises an inner narrow circumference; the inner bottom portion of the inner surface comprises an inner bottom circumference; the inner narrow circumference is less than both the inner top circumference and the inner bottom circumference; and the inner surface is configured to matingly engage with a finger of a user such that when the ring is placed on the finger it is held substantially in place and is substantially prevented from being accidentally removed from the finger.

Disclosed is a spinnable jewelry item, including: a rotating assembly having a rotating face and a main shaft connected with the rotating face, the rotating face rotating with the main shaft as axis; a positioning assembly having a positioning face, the positioning face elastically abutting against the rotating face along the axial direction of the main shaft; a protrusion and a recess opposite the protrusion being provided on opposite surfaces of the positioning face and the rotating face; when the rotating face is rotated, the protrusion enters or exits the recess; an elastic element applying an elastic force against the positioning assembly, such that the positioning face resiliently abutting against the rotating face; a main body part having an opening structure, wherein the main shaft is rotatably connected with the bottom of the opening structure after passing through the positioning assembly and the elastic element, and the positioning assembly and the elastic element are disposed in the opening structure. the spinnable jewelry item has a structure that can be rotated to be positioned, such that various vies of the jewelry item can be well presented, thereby better satisfying a consumer's demands on versatility.
