  1. GM SDM Module on Car Owners to be Notified of Blackboxes in Vehicle · · Score: 0

    You could probably disable this by removing the CAN / ODB communication wires connected to the recording device. The problem is that GM is incorporated their black box into the air bag SDM module.

    Tampering with that module my not be the brightest idea.

    I know that Toyota sends information on their communication bus to the air bag module. For example there are occupancy sensors in the seats. Why fire the airbag for the passenger if there isn't a passenger?

    So, again, disabling the communication lines to that module may be a bad thing.

  2. Patent what? on Tapping Trees for Electricity? · · Score: 0, Redundant

    The main problems is that he hasn't the slightest idea how to get useful electricity from a tree but yet he was able to apply for a patent. You can drive a ground rod and hoist a copper plate in the air. There will be an insignificant amount of energy generated between the two. Maybe I could patent that and the act of putting electrodes into a potato.

  3. Re:Can you hear me... Can you hear me now... on Driving Away Teens With High Frequency Noise · · Score: 1

    I have no experience with hearing aids but this seems like a simple solution. Why not shift the 500-4000Hz range to a range that you can still hear?

    "Then there's the self-oscillation ("feedback"); since these things use IIR filters instead of FIR filters, they tend to go unstable at odd times, usually as a result of some sound that is barely audible, or a pure sinusoidal sound, like many computer beeps and alarm sounds. Solution? Cycle power on the devices. It's a Windows world, and these don't even run Windows. "

    Right. No feedback but more processing power and memory.

    "Now, a device like this will likely make me effectively deaf. How? The hearing aids set their overall gain based on the sound level in the room, regardless of band. Thus, they will sense the loud HF sound and cut the gain way down, so, from my point of view (hearing?), the world will suddenly get really quiet. "

    I don't understand why a hearing aid would even be that sensitive to a range of frequencies that you can hear. I have no experience in hearing aid design but it seems to me that a manufacturer would map your range of good frequencies and customize a hearing aid from that data.
