Talk:Active Protection System
Hi, is it worth to contact ibm in some sort of conserted effort to get this going?
Just found this thread, http://www.ussg.iu.edu/hypermail/linux/kernel/0412.1/index.html#0544.
Of particular interest is some code that got posted there. --Danguy 05:28, 28 Apr 2005 (CEST)

useless code
This (C#) code is useless.
It does not read the actual sensors which gets done by a seperate device driver (shockprf.sys)
IBM not interested
I have contacted IBM several times on the providing of specs for the APS. They are simply not interested. And yes, everybody within IBM may at any time experiment with Linux. But no, since there is no commercial interest for a Linux-port of this APS-feature, they are not doing it.

discussion on the kernel mailing list
There has been some ongoing discussions about HDAPS on the linux kernel mailinglist: [1]
maybe something comes out of this,
tamer.
Today I recorded data from a ride home. The result is at http://thebe.orbit.homelinux.net/~alphaone/data.ps
Tools used to create it are in /util in my svn rep.

Table parameters
What do all the parameters in the table mean?
'Thinkpad' is obvious. Perhaps 'Model' makes more sense.
'bios firmware' is also obvious, but the output of # biosdecode calls it 'BIOS Build ID'. It should probably say how to determine the firmware version.
What are 'latch' and 'flip'?
'Value at 1.75' is explained below. How useful is it that the tilt be exactly 1.75 radians (and not 1.74 for example). Also, 1.75 radians between what and what? Between a flat surface and the keyboard? Or between a flat surface and the LCD when the LCD is perpendicular to the keyboard?
Same question for 'Value at 0.75'
I just added 'Value at rest'. By that, I mean when the tablet is resting on its base on a flat surface. LCD position is immaterial. Keyboard - flat-surface angle is 0.
What is 'boxers'?
'hdd-type' I believe HDD model number from # hdparm -I /dev/sda. It should be clarified.
In the second table, 'firmware', I believe, refers to the HDD firmware. This is the result of the 'Firmware Revision' value from # hdparm -I /dev/sda
As for 'parked', there probably is a way to tell whether or not it gets parked. I haven't looked into it.
Does the information in that table help anyone at all? It seemed good for development of the hdaps driver, but that's already in the kernel. Do we need that table? Otherwise I'd remove it soon.
And I'd move the harddisk firmware table to the Problem with APS harddisk parking page, then.
