A wearable device allows women to track their menstrual cycle by rotating or sliding a marker that will tell her every day where she is in her menstrual cycle. This device can be shaped in multiple ways. In general, the device has two or more interlocking pieces that allow the user to manually move, e.g., rotate or slide, a marker shaped on one of the pieces with respect to the other piece to highlight indicia, such as a number or icon or color, that represents a day in the menstrual cycle. The indicia can be hidden within the design to protect the user's privacy. In one implementation, the device is attached to a chain, rope or other form allowing it to be worn around the neck, typically under the clothes, like a pendant. Another implementation is shaped like a bracelet, allowing it to be work around the wrist. Other configurations to be worn on other parts of the body also are possible.

A method for iNecklace-iAlphabet-iUniverse comprises receiving a request for intuitive structures from the environment, constructing the iAlphabet, computing the identity, performing algebraic, categorical, and homotopy type constructions, performing constructions with measures, recalling relevant instances with reconstructions, identifying the analytic device, enabling composability to construct iUniverse.

A jewel (M) comprises a main element (1) formed by a metallic cable (2) provided with two opposite ends (E1, E2) adapted to be connected together in a loop by the connection unit (4), and battery means (7) carried by said connection unit (4); said element (1) supports a plurality (5) of LED means (6) connected to each other by said cable (2) and adapted to be lit when said element (1) is connected in a loop by said connection unit (4).

A timepiece includes a representation of a non-rectilinear object, the representation particularly including a movable element kinematically connected to a drive mechanism. The representation also includes at least one second movable element, the drive mechanism being arranged such that the movable elements each move, simultaneously and in synchronization, between a first and a second end position, and vice versa, the movable elements forming the representation at a first size and at a second size greater than the first, respectively, when the movable elements are in the first and second end positions thereof.

Some embodiments of the present technology include a system for wearable technology with creative expression including a personalized electronic jewelry device, the personalized electronic jewelry device being configured to receive a personalized input. In some embodiments the system includes a digital display, the digital display being seamlessly housed in the personalized electronic jewelry device. In various embodiments the digital display is coupled with the personalized electronic jewelry device and is configured to display the personalized input.

A light emitting earring. The light emitting earring includes a light emitting unit comprising a base having a first side and second side, one or more LEDs disposed on the first side, and a pin disposed on the second side. A pattern generator operably connected to the light emitting unit includes an aperture configured to receive the pin therethrough. A retainer having a battery therein is removably securable to the pin via a retainer clip, such that the pattern generator is positioned between the light emitting unit and the retainer. The pattern generator is configured to cause the one or more LEDs to flash in a desired pattern.

Provided is a 360-degree rotatable accessory. The 360 degree rotatable accessory can be used for various purposes such as a decoration of a bag, or a finger ring, a necklace, a bracelet, and an earring, can be rotated a predetermined angle, that is, 360 degrees around a coupling portion, that is, a body, and can be transformed into various shapes because it can be rotated a desired angle and firmly maintained at the angle, thereby having high commercial value and quality.

This is a particular style of decoder ring. It is based on a spinner ring that is worn on the finger. It has a band that spins, and a small window cut out of that band. The window allows characters on the surface below to be read one at a time as the window passes over them.
