Simple really, the OBC has a dynamic memory that only saves, say, 5 seconds at a time. When an event, such as an accident occurs, the flow of information to the OBC stops, therefore it will "store" the last active 5 seconds and hold it available for download in the event of the information being required for insurance or legal purposes. The OBC will not have sufficient memory to record transgressions over a longer period of time. Of course, Fleet owners make use of a similar device which can store up to 24 hours or more of information, but they do it in the interests of their expensive investment of 18-wheelers and the like, and they do want to know about bad driving habits, etc. Eric That Guy In Africa... http://gds.co.za/northcom/ ******************************************** ICQ# 39461303 ~ Greetings from Sunny South Africa ~ ******************************************** -----Original Message----- From: pctechtalk-bounce@xxxxxxxxxxxxx [mailto:pctechtalk-bounce@xxxxxxxxxxxxx]On Behalf Of MSVERKO@xxxxxxx Sent: 15 April 2003 07:16 PM To: pctechtalk@xxxxxxxxxxxxx Subject: -=PCTechTalk=- Re: my new car is a spy In a message dated 4/14/03 7:31:45 PM Eastern Daylight Time, John82654@xxxxxxx writes: > I think you're forgetting how do they know 5 seconds before the impact in an > > accident that hasn't happened yet? I was thinking the same thing. maybe backs up every couple of minutes to give data.
