Talk:Sudden Motion Sensor

From Wikipedia, the free encyclopedia

uhm, whoever wrote this dosn't know how gravity/accelerometers works. Dropping a laptop dosn't cause a sudden acceleration, it causes a sudden lack of acceleration.

[edit] Patented?

How did Apple patent Sudden Motion Sensor if IBM has IBM Active Protection System? I've seen it myself on Macworld Expo 2006 keynote broadcast that Steve said that Apple invented the Sudden Motion Sensor, but is it actually true?

“Sudden Motion Sensor, which is you know Apple invented and holds all the patents for”, — Steve Jobs at Macworld Expo 2006 keynote in January 2006 about Standard Features of MacBook Pro.

I don't know about patents. Perhaps it uses a diffrent technology or sensor for the same end result? I'm using a thinkpad right now, with APS... let me assure you it is the most useless feature I have ever seen. It begins to get very annoying when your music/movie stops as you simply adjust the laptop. I turned it off within a couple weeks... and am blissfully happy without it. --AK7 05:26, 23 January 2006 (UTC)

Oh, and shouldn't this article be called APS, with a refernce to SMS, since nAPS was first? Or shouldn't APS have it's own page? --AK7 05:27, 23 January 2006 (UTC)

The usefulness of Sudden Motion Sensor and IBM Active Protection System is another question all together. :-) Going back on the topic:

1. It probably should not be called SMS.

2. It probably should be clarified that origin of the Apple patent is unknown.

3. Yes, IBM's APS might as well have it's own page if someone writes one for it. :-) MureninC 14:22, 23 January 2006 (UTC)

[edit] Counts per gravity?

The article states that the technology "resolved 52 counts per gravity". Is this a measure of the sampling rate of g-forces, or something else? The explanation needs to be clearer to non-specialists. — Loadmaster 16:53, 17 June 2007 (UTC)
