Information is immediately forwarded to preset second contact person.The process continues, until at least one Related Contact receives accident
Information simultaneously confirms that it is received.Other optinal plans for operational notification function are described elsewhere herein.
In one example, accident condition can be based between acceleration information and the time occurred about event (acceleration)
Every data combination.Alternatively, accident condition can be based only upon acceleration information and/or be based only upon spin data.At one
In example, if acceleration is greater than acceleration rate threshold, and the time that acceleration occurs is less than time threshold, it is determined that may be
There are true accidents.If acceleration is less than acceleration rate threshold and/or the time is greater than time threshold, judge that data are not from
Accident.As non-limiting example, in one case, if acceleration is at least 30 gravity (g), there are latent defects.
In this example, be not more than 3 milliseconds (ms) in case of the time interval of at least 30g acceleration, it is determined that there are it is actual can
Report accident.When acceleration is less than 30g and/or acceleration event time interval is greater than 3ms, actual accidents are not present in judgement.
Note that specific acceleration and time restriction are not limiting, and it is exemplary.For example, when sample rate is 1kHz, 3ms
Interior there are three samples, this may provide enough redundancies to prevent from reporting by mistake.In other words, if three continuous-readings are limited higher than g
System, then reading may be effectively.
In some cases, low g and hight Tc superconductor can be used simultaneously.This will allow using multiple acceleration rate thresholds
(for example, 30g and 50g), this can be interpreted the seriousness for determining accident.For example, if meeting low g and high g limitation, thing
Therefore may be very serious, and if only meeting lower g limitation, accident may be less serious.It can be according to severity of injuries
Carry out customised notification message.
Accident condition can also be based on the rotation detected.For instance, it may check from IMU spin data (one,
In two or all three orthogonal axis) to determine that it is more than the rotation amount in given time, indicate turning over for automotive seat
Turn.If children are on the seat, such as by there are sensors to determine, and turnover seat, it assumes that accident has occurred.With acceleration
Equally, rotary sensing can (but not necessarily) join with the time correlation for determining whether there is true accident.For example, it may be determined that
It is as caused by true traffic accident that a certain amount of (for example, 180 degree) is rotated in short time.Or the speed of rotation can be used rather than revolve
Turn amount, or the speed of rotation can also be used other than rotation amount.As acceleration, multiple threshold rotating values can be used.
It can determine that time threshold may be the other reasons tumbled etc due to accident rather than due to the accident of such as automotive seat.
As described above, search and transfer capability are activated to search for contact person simultaneously when can actually accident be reported by detecting
Contact person is sent by the notice that accident has occurred.It can require the people contacted after receiving accident information, preferably
In scheduled short time period, notice receipt is returned.If search and retransmission unit ability do not receive back in specific time
It holds, then search and transfer capability find next contact person and forward accident information.This process will continue, until receiving receipt.
