Baseball pitch selection communication system
A system for communicating pitch selections wirelessly from a wireless transmitter has a coded signal generator that generates coded signals in accordance with selected pitch types. A receiver decodes the received coded signals, selects an audio file based on the received coded signal and generates an audio signal announcing the selected pitch type based on the transmitted selected pitch type in accordance with the received coded signal. The audio signal is transduced by a bone conductor transducer so that the player can hear the announced selected pitch type through bone conduction.
1. A system for communicating pitch selections wirelessly, the system comprising:
a transmitter having a signal generator that generates a coded signal in accordance with a selected pitch type, and a wireless transmitter coupled to the signal generator and configured to transmit a coded wireless signal signifying the selected pitch type in accordance with the coded signal;
a wireless receiver that decodes the received coded wireless signal, selects a stored audio file corresponding to the selected pitch type based on the received coded signal and generates an audio signal from the stored audio file; and
at least one bone conductor that transduces the audio signal into a human-perceptible signal.
2. The system of claim 1 , wherein the wireless transmitter is a spread spectrum wireless transmitter that transmits the coded wireless signal as a spread spectrum signal.
3. The system of claim 2 , wherein the spread spectrum signal is transmitted using a frequency-hopping spread spectrum transmission protocol.
4. The system of claim 3 , wherein the spread spectrum signal is transmitted using a direct-sequence spread spectrum transmission protocol.
5. The system of claim 2 , wherein the transmitter includes a plurality of human-actuatable elements that are actuated by a user to select the selected pitch type.
6. The system of claim 5 , wherein the plurality of human-actuatable elements are individual buttons.
7. The system of claim 6 , wherein the transmitter is a wrist-worn device.
8. The system of claim 5 , wherein the transmitter is a tablet device.
9. The system of claim 1 , wherein the wireless receiver substantially fits within a sweatband of a baseball style cap.
10. The system of claim 9 , wherein the wireless receiver has a single bone conductor, the wireless receiver sized to fit within the sweatband on only one lateral side of the baseball style cap.
11. The system of claim 9 , wherein the wireless receiver has multiple bone conductors, the wireless receiver sized to fit within the sweatband around a back of and along both lateral sides of the baseball style cap.
12. The system of claim 11 , wherein the wireless receiver has an approximately semi-circular substrate that fits within the sweatband, and an electronics board on which electronic components of the wireless receiver are mounted to the substrate, wherein the multiple bone conductors are mounted on the substrate and coupled to the electronic components of the wireless receiver.
13. The system of claim 12 , wherein the electronic components of the wireless receiver include a battery, a microcontroller coupled to the battery, a receiving unit coupled to the microcontroller, and a memory coupled to the microcontroller.
14. The system of claim 13 , wherein the wireless receiver includes an antenna coupled to the receiving unit and extending along a periphery of the substrate.
15. A system for communicating a selected pitch type to a person wearing a baseball hat, comprising:
a transmitter having a signal generator that generates a coded signal in accordance with a selected pitch type, and a wireless transmitter coupled to the signal generator and configured to transmit a coded wireless signal signifying the selected pitch type in accordance with the coded signal;
a hat with a wireless receiver that decodes the received coded wireless signal, selects a stored audio file corresponding to the selected pitch type based on the received coded signal and generates an audio signal from the stored audio file; and
at least one bone conductor that transduces the audio signal into a human-perceptible signal.
