## Title
Wireless play communication wristband

## Abstract

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.

## Background
FIELD OF THE INVENTION
This invention is a device that strengthens the play transmission and understanding between players and coaches during game play.
BACKGROUND OF THE INVENTION
Coaches are always trying to communicate plays or certain aspects of plays during a game to their players. Some coaches use a play sheet and a numbered play sheet wristband to signal plays,
some coaches use hand signals to transmit plays to players, some coaches use storyboards with figures and hand signals to send plays to players. These methods of sending play information are archaic at best. Often times signals are confused resulting in the wrong play being called.
This invention solves the play communication problems. The coach is able to press a button on a wireless Bluetooth/Radio Frequency/Infrared device and light the corresponding LED on the player's wristband.
SUMMARY OF THE INVENTION
The invention relates to strengthening coach to player communication during a sporting event presenting light emitting diodes (LED) lights associated with corresponding plays inserted next to or over the LED lights signifying a correct play call.
The invention is a wristband of elastic, or adjustable design with a clear, see-through plastic window displaying the LED lights and corresponding plays, and a velcro enclosure opposite the clear plastic window, which houses the electric components: microcontroller, RF/IR/XBEE/Bluetooth wireless controller, battery power supply.
The wristband invention will link wirelessly with any wireless device that a coach uses to transmit a signal to light the play LED on the invention (player's wristband). The wristband will link with Bluetooth on a cellular device, Radio Frequency or XBEE from an RF panel, or an Infrared device, by changing out the corresponding wireless Bluetooth, XBEE or RF transceiver, Infrared receiver in the wristband enclosure wired to the microcontroller and the battery power source.
A coach presses a button on his wireless device and the signal is received via the wristband's wireless receiver and the signal is interpreted by the microcontroller (powered by the battery power source), and sends the signal to an appropriate LED to light next to a desired play.
This invention is useful to almost any sport where a coach needs to send plays in to players on the field/court/pitch.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The following discussion describes in detail an embodiment of the wireless play wristband apparatus. This discussion should not be construed, however, as limiting the invention to this particular embodiment.
FIG. 1 is an illustrative view of the top side of the wristband invention illustrating a first LED 10 of a LED matrix. FIG. 1 also illustrates the wristband 15, which is made of elastic, or adjustable material. The LED Matrix is covered by a clear (see through) plastic window. There is also a slot to slide plays between the LED Matrix and the clear plastic window. A player will be able to see the LED light next to the corresponding play 20 through the clear plastic window on the top of the wristband 15.
FIG. 2 is an illustrative view of the bottom of the wristband invention. FIG. 2 illustrates a velcro enclosure that will house the electronic components for wireless communication and LED controls.
FIG. 3 is an illustrative view of a programmable LED strip. Several LED strips can be wired together to create a Matrix, or an LED Matrix can be used (FIG. 7; LED Matrix 23).
FIG. 4 is an illustrative view of a Bluetooth universal asynchronous receiver/transmitter (UART) wireless controller 30. The Bluetooth UART wireless controller 30 will accept Bluetooth pairing for remote wireless connectivity from a cell phone, or tablet (or any Bluetooth paired device). The Bluetooth UART wireless controller 30 is wired to a microcontroller.
A Radio Frequency (RF), or XBEE, or Infrared (IR) device may also be used for wireless connectivity.
While certain novel features of this invention have been described in the Detailed Descriptions above, it is not intended to be limited to said details, since it will be understood that various omissions, changes, and substitutions in the forms of details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the wristband invention.
FIG. 5 is an illustrative view of a microcontroller 25. This microcontroller 25 contains the programming allowing the wireless controller (Bluetooth, RF, IR, XBEE) to connect and control the LED Matrix within the wristband.
FIG. 6 is an illustrative view of a power source 40. The power source 40 is typically a 3.3V or 5V power source. The power source 40 is rechargeable via Universal Serial Bus (USB) connection to a PC or another USB power source.
FIG. 7 illustrates the LED Matrix 23.
FIG. 8 is an illustrative view of a circuit assembly. FIG. 8 illustrates a first LED 12 on a LED strip 35. FIG. 8 also illustrates the wiring 17 between each LED strip 35 (an LED Matrix may also be used, see FIG. 7). Three wires connect each LED strip and eventually connect to the microcontroller 25, then the microcontroller 25 is wired to the wireless controller 30.
FIG. 9 is an illustrative view of the communication process. FIG. 9 illustrates a button 46 on a remote wireless device 45 (cell phone, RF, XBEE, IR transmitter). The remote wireless device 45 pairs with the wireless controller 30 on the wristband, then the wireless controller 30 passes a received signal through to the microcontroller 25, which sends a signal to the programmable LED strip 35. Therefore, the first LED 12 of FIG. 8 is lit when the button 46 is pressed on the wireless wristband.
