Frequency of Movement*:
0.4 (low) to 0.6 Hz (high)
Displacement:
7 to 10 cm
Force:
8.7 - 16 N
Weight:
9 kg
Cost:
$341.22
Dimension:
80 cm (width) x 50 cm (length) x 30 cm (height)
Installation:
One time assembly; may be difficult to set up alone while in wheelchair
Adjustable to Individual:
Fits leg diameters of 13 cm
Operating Time:
6 hours
Software Interface:
Allows user to control device program while lying down;
Operates in a range of 6 ft;
Wide range of control: automatic mode for sleep; manual control for wake
Minimal interference
Safety:
Causes no short or long-term damage to user
Contains no toxic materials or chemicals and no exposed electrical components
Cords not harmful or disruptive to user
Low friction: avoids sores due to friction over long term use
Comfort:
Legs lifted 17 cm;
0.05 kg weight rest on the legs; comfortable to use throughout the night while maintaining normal sleep
Sound:
48.1 - 61 dBA
*The Sun Ancon Chi Machine, an existing solution, has a frequency of 2.33 Hz, but this frequency is not suitable for use during sleep.
(Another group is working on a sensing device for PLMs, so our device would ideally be compatible with theirs)
