But the big VR players are still working out motion tracking. When you look down with a VR headset on the first thing you want to do is see your hands in a virtual space. For a while, we've seen the Leap Motion accessory - which uses an infrared sensor to track hand movements - strapped to the front of Oculus dev kits.
Urine specimens should not remain unrefrigerated for longer than two hours. Aurine specimen that cannot be delivered to a laboratory within two hours should be stored in a refrigerator. The reason for this precaution is that urinesamples undergo chemical changes at room temperature.
When I know I'll be tested, I thaw the urine at room temperature overnight (still sealed). At most it's at room temp for 6-8 hours. There will invariably be sediment collected at the bottom of the sample and that is normal. frozen urine sample can last up to one year. I haven't tested this-but it seems to be the general consensus on these forums and on other discussions I've seen on the net. I've used urine stored for over a month without complications, so using yours after a week of storage should be fine.
