This invention is intended to strengthen play transmission between players and coaches before, and during plays. The wristband is an elastic, or adjustable wristband with a clear plastic window and LED strips or LED matrix that lights the Light Emitting Diode (LED) next to a desired play. The wristband is wirelessly linked to either a radio frequency panel, bluetooth device, or infrared controller. The wristband LED's are wired to a microcontroller, Bluetooth controller (or RF transceiver, or Infrared controller), and a battery power source. The LED's are displayed through the clear plastic window and the plays are slid over the top of the LED's. The micro controller, battery and wireless controller are contained in a velcro-enclosed, low-profile enclosure opposite the clear plastic window.

Disclosed is a catenary equipment including a pillar unit which comprises a first pillar member and a second pillar member to be arranged at regular intervals; a horizontal wire which is horizontally arranged in between the first pillar member and the second pillar member; a horizontal-wire holder unit which comprises a first horizontal wire holder installed on the first pillar member, and a second horizontal wire holder installed on the second pillar member; a horizontal-vibration absorbing member which is arranged in between the horizontal wire and the first horizontal wire holder; a holding wire which holds the horizontal wire; a ceiling holder which is installed at a ceiling of the building; a connection bracket which connects a second end of the holding wire and the horizontal wire; and an earthquake-proof lighting equipment assembly which is installed on the horizontal wire.

A low-noise light fixture reset structure includes a pivot shaft and a pivot member rotatably connected to the pivot shaft. The pivot shaft is fixedly connected with a drive wheel and is sleeved with a shifter lever on which a first detection marker is provided on the shifter lever. A first detector configured to detect the first detection marker is provided on the pivot member. A first limiting post configured to limit the shifter lever is also provided on the drive wheel. The pivot member is further provided with an elastic member capable of resisting against the shifter lever and a second limiting post that limits the shifter lever. The second limiting post, the elastic member, and the first limiting post do not interfere with each other during a relative movement between the pivot member and the pivot shaft.

Disclosed herein is a luminaire apparatus having an air cleaner attached thereto, which is connected by wires and cables so as to be vertically movable. More particularly, the luminaire apparatus enables a luminaire and air cleaner, which are considerably heavy, installed on a ceiling to be safely moved vertically using wires in order to perform replacement of light bulbs, replacement of air cleaner filters, troubleshooting, or maintenance, and is usable through supply of power to the luminaire and the air cleaner at a desired height by installing the air cleaner capable of vertically moving together with the luminaire and by installing power cables capable of supplying power even when the luminaire and the air cleaner are moved up and down.
