A first bracelet having physical buttons may be touched in a defined sequence and for a length of time to complete a shared activity across a group of bracelets. The first bracelet may communicate a signal that includes information identifying completion of the shared activity. A second bracelet may receive a signal that programs physical buttons such that they may be touched for the length of time to complete the shared activity by repetition of the defined sequence.

An articulated cross pendant, such as may be worn on a necklace around the neck of a user, is disclosed. The pendant has an upright bar crossed by a horizontal bar. The horizontal bar has right and left arms extending to the left and to the right of the upright bar, respectively. The upright bar may have an upper portion extending upward and a lower portion extending downward from the horizontal bar. The lower portion may be elongated such that it is longer than the upper portion and longer than each of the right and left arms of the horizontal bar. The top end of the upper portion may be looped, and the lower portion is fully articulated to prevent the ends of the upright bar, worn on a necklace, from poking or piercing the skin of a user when the user bows the head downward toward the chest.

An embodiment of the present invention provides a counting information updating method for a portable electronic device having a plurality of spheres connected with each other. The method includes: generating an angular velocity signal by a first sensor of the portable electronic device and generating an acceleration signal by a second sensor of the portable electronic device in response to a sphere moving operation; and estimating counting information corresponding to the sphere moving operation by using the angular velocity signal with an assistance of the acceleration signal.

A terahertz healthy rosary structure includes a rope, a plurality of serial-connected rosary bead configured on the rope, a first rosary bead configured on the rope, and a plurality of terahertz layers formed on the surfaces of the serial-connected rosary beads and first rosary bead, where the two sides of the first rosary bead are respectively connected with the serial-connected rosary beads. When a user hangs the rope on the neck, uses it for singing Buddha, or places it close to the body, the terahertz layers will then emit terahertz waves. After the human body absorbs the terahertz waves, it can achieve the effects of promoting blood circulation, enhancing metabolism, and regulating autonomic nerves.

A rosary includes a first section of a chain closed as a ring with five groups of beads divided in decades sliding freely thereon, the five groups of beads being spaced by a single bead that separates each group from the others; a second chain section connected to the first chain section and terminating with a crucifix, wherein the crucifix is divided in two parts and wherein, in proximity to each one of the two parts of the crucifix, there is at least one recess suited to house a part of the first ring-shaped chain section, so that when the two parts of the crucifix are joined in order to accommodate the part of the first ring-shaped chain section therein, the rosary assumes the shape of a bracelet.
