Audio signal conveying power supply
First Claim
1. An audio signal conveying power supply configured to provide an output voltage to an electrically powered helmet and an additional audio headset, the audio signal conveying power supply comprising:
- a. a housing;
b. an audio and power signal inlet port in the housing for receiving audio signals, power, or both audio signals and power from a vehicle audio and power cable connected to a vehicle;
c. an audio and power signal outlet port in the housing for transmitting the audio signals, power, or both audio signals and power to an audio and power cable connected to the electrically powered helmet;
d. an independent audio cable in the housing connecting from the audio and power signal inlet port to the audio and power signal outlet port;
e. a battery pack in the housing electrically connected to the audio and power signal outlet port;
f. at least one power converter in the housing coupled between the battery pack and the audio and power signal outlet port;
g. a control circuit connected to the at least one power converter, an on/off switch, an active noise reduction switch, a low battery light, a fault light, and a helmet power switch, the control circuit configured to;
i. turn on or off the audio signal conveying power supply when the on/off switch is activated;
ii. open or close the active noise reduction switch;
iii. activate the low battery light when the battery pack has a low battery;
iv. activate the fault light when the battery pack has a fault within the housing; and
v. open or close the helmet power switch to change operational mode of the battery pack from a primary power to a secondary power and transfer power from the vehicle to the battery pack; and
h. a charging port formed in the housing configured to accept power from a power supply or from the vehicle to charge the battery pack in the audio signal conveying power supply.
