A terahertz healthy rosary structure includes a plurality of serial-connected rosary bead that include a silicon material and emit a terahertz wave, a through hole, a rope-based fixing structure, and a first rosary bead that includes a silicon material and emits a terahertz wave. The through hole is formed in the serial-connected rosary beads. The first rosary bead is arranged on the rope-based fixing structure and two sides of the first rosary bead are each connected with a respective one of the serial-connected rosary beads, so that the rope-based fixing structure connects each of the serial-connected rosary beads and the first rosary bead in series to form a rosary bead structure having a predetermined shape. The serial-connected rosary beads and the first rosary bead emit a terahertz wave that has a frequency of 0.1-10 THz and a wavelength of 0.03-3 mm to be absorbed by the human body.

A rosary designed to provide light to the user engaged in prayer, eliminating the need for the use of candles or phosphorescent rosaries in vigils and dimly lit churches. The Rosary is composed of a plurality of beads encompassed around LED enabled wire attached to a printed circuit board located in the Rosary's medallion. Also attached to the Printed Circuit Board is an LED enabled crucifix. The Printed Circuit Board is LED enabled as well, and contains a power switch that provides all parts of the Rosary with power from the Rosary's battery, also contained in the medallion. The Rosary provides a source of light to users and is designed to withstand outdoor climate conditions such as wind and rain, providing an additional benefit over the use of candles in prayer.

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.

This tool for recording the number of swings in a ball game includes a plurality of holed beads 20 and a cord 30 that is passed through the holes 20H of the beads 20 and that holds the beads 20 so that the beads 20 can slide, the cord 30 is formed from a cord material that does not stretch in an axial direction but that stretches in a diametrical direction and that is normally urged in a diameter-expanding direction, and the cord 30 constrict in diameter so as to elastically interlock with the walls of the holes 20H of the beads 20 and hold the beads 20 in position, whereby the beads do not shift even if a player strongly shakes the tool, the number of swings in the ball game can be reliably recorded and confirmed, and the tool is easily assembled.

System, methods, and other embodiments described herein relate to performing an activity using multiple bands. In one embodiment, a method includes touching a subset of inputs, associated with a sensing device of a first band that is wearable, involving an activity with a second band. The method also includes communicating, by the first band, first data to a first mobile device, the first data including information that identifies completion of the activity and indicates a time that the subset are selectively touched, wherein the first band directs the first mobile device to communicate second data to a second mobile device to conduct the activity.
