Methods and apparatus for recording impulsive sounds
Loud sounds with fast rise times, like gunfire and explosions, can cause noise-induced hearing loss (NIHL). Unfortunately, current models do not adequately explain how impulsive sounds cause NIHL, which makes it difficult to predict and prevent NIHL on battlefields and other hostile or rugged environments. Fortunately, the impulsive sounds experienced by soldiers and others working in rugged environments can be recorded using a compact, portable system that acquires, digitizes, and stores high-bandwidth audio data. An example of this system can be mounted on a helmet or other article and used to record hours of audio data at a bandwidth of 20 kHz or higher, which is broad enough to capture sounds with rise times less than 50 ms. An analog-to-digital converter (ADC) digitizes these broadband audio signals at rate of 40 kHz or higher to preserve the impulse information. A processor transfers the digitized samples from a buffer to a memory card for later retrieval using an interrupt-driven processing technique. |

A firewall system determines whether a protocol used by an incoming data packet is a standard protocol compliant with Request For Comment (RFC) standards. In the event the protocol is RFC compliant, the firewall transmits the packet to the recipient according to firewall policies regarding the standard protocol. If the protocol is not that of an RFC standard, the firewall determines whether the protocol matches an RFC-exception protocol in a RFC-exception protocol database. If the protocol does match an RFC-exception, the firewall may transmit the packet to the recipient according to firewall policies regarding the RFC-exception protocol. If it does not match an RFC-exception, the firewall may transmit the packet or protocol to a support system where it may be quarantined until it is approved based on a decision that the protocol is safe and/or widely adopted. |
