  • Arm harness with a control panel for operating multiple electronic devices
    Patent number: 6577499
    Abstract: The present invention relates to an arm harness with a control panel for operating multiple electronic devices contained by the arm harness. The present invention enables a user to conveniently carry electronic devices, such as a cellular phone, an audio player (e.g., tape player, mini-tape player, CD player, etc.). The present invention enables a user to perform other activities by freeing up the user's hands while enabling the user to enjoy music or other recording, communicating by a cell phone etc. The present invention also facilitates transportation of electronic devices in containers within the arm harness of the present invention. The control panel may include a display and control buttons that operate the electronic devices contained by the arm harness. In addition, the control panel may control the sound and other audio qualities emitted by the electronic devices attached to the control panel.
