The present invention relates to as battery box comprising a housing and a power supply component mounted within the housing. Through holes are provided respectively on both ends of the housing to lead a wire into the housing to connect with the power supply component. The power supply includes a circuit hoard and a battery. The housing includes an upper housing body and lower housing body which are detachably connected with each other. The upper housing body and the lower housing body could be engaged with each other to form a receiving cavity to receive the power supply component. A contact is provided on the circuit board to be in communication with the battery and correspondingly, a flexible sheet is provided on the upper housing body to press the contact. The present invention further relates to a necklace provided with the said battery box.

An ornamental enclosure and an emergency alert device comprising of a removable housing with a through hole with a actuator button placed within the through hole that is adjacent to the activation button of the alert device. Retainer tabs hold the alert device in place. The ornamental enclosure is distinguished by attachment mechanisms that are a belt buckle configured to engage a belt or a fastener configured to engage a wristband or bracelet. There is a free floating activation push button placed within the ornamental housing which depresses an adjacent actuator button that is positioned to engage the activation button of the alert device. Another embodiment is an ornamental enclosure with a through hole housing common internal emergency alert circuitry, a generic energy source and an activation push button placed within the through hole. The push button is adjacent to an actuator that when pressed causes the actuator to engage a common micro circuit board switch activation mechanism of the generic internal emergency alert circuitry. A variety of durable materials, styles and attachments may be utilized.

A light string with a snap-fit enclosure includes a conductor, a light element mounted to the conductor, a shroud having a body having an open interior and a neck, the neck having an opening therein, open to the body interior and a cap configured to fit onto the neck. Cooperating locking elements are positioned in the cap and on the neck to lock the cap to the neck, such that the cap is secured to the neck and the light element secured within the shroud without the need for an external fastener. At least one of the cap and the neck have at least two cut-outs formed therein opposing one another and defining a channel. The channel is configured to receive the conductor with the cap secured to the neck.

A slap wrist device includes a bottom strip having top and bottom surfaces with at least the top surface of thermoplastic material, a middle strip having top and bottom surfaces and of or coated with a thermoplastic material, and a top strip having top and bottom surfaces, at least the bottom surface being of thermoplastic material. A bistable spring is disposed between the bottom and middle strips, and a light emitting and elongated flexible light transmitting element is disposed between the top and middle strips. The bottom and middle strips are sealed together by high frequency (HF) welding along substantially their entire peripheries, and the top and middle strips are sealed together by HF welding along at least the majority of their peripheries. A battery casing, with or without an external safety light, or a fabric bag, may be mounted to an end of the device.

An electronic necklace comprising a projector medallion and associated methods of formation are described, and more particularly to an electronic necklace with one power source for powering a projector medallion and necklace bulbs and its associated methods of formation. In one embodiment, an apparatus may include a wire serving as a necklace strand with a projector medallion formed of a translucent material including a backside, a front side, an underside, and/or an interior. The necklace may include a power source in the form of a battery. The necklace may include a projector light and/or a medallion light within the interior of the projector medallion. The necklace may include a control chip within the interior of the projector medallion that may distribute power from the battery to the wire, the projector light, and/or the medallion light.

Illuminated jewelry wearable as earrings, body rings, necklaces or the like includes a single or multiple light source(s) that cast, scrape, front light and otherwise illuminate the jewelry desired either incorporated there in or adjacently. Additional desirous effects may include body/skin illumination directly, indirectly, reflected or refracted. Light source(s) can include LED(s), chemo luminescence, incandescent, electro luminescent or other.

A lighting structure and a wearable device are provided. The lighting structure is provided, including at least one light source, a battery, and a control module. The at least one light source includes one or any combination of a first light-emitting diode (LED), a first electro-luminescent (EL) wire, a first optical fiber, and an organic light-emitting diode (OLED). The battery includes either a disposable battery or a rechargeable battery. The lighting structure includes the at least one light source and the battery, the at least one light source is configured as including a plurality of light-emitting materials or a single light-emitting material, and power supply modes of the lighting structure are also various, so that optimal lighting effect of the lighting structure is achieved.

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.
