Abstract: The present invention provides methods and devices for using feedback to improve non-invasive tissue measurements by making measurements faster, easier to perform, and less error prone. In some embodiments, a set of metrics is identified as measurable potential sources of measurement error that can be controlled by a user. In some embodiments, the set of metrics can be analyzed to determine which metrics are related to one another, and some possible error metrics can be discarded, and others used as surrogate metrics for measuring and monitoring measurement errors.

Abstract: A support device is provided for leaning against by a generally upright person. The support device includes a seat portion having a top surface, a bottom surface and a peripheral edge extending between the top and bottom surfaces. A plurality of legs each has a first end and a second end. Each of the first ends is pivotally attached to the bottom surface of the seat portion. Each of the legs is located generally adjacent to the peripheral edge. The legs are spaced from each other. The legs are each telescoping and selectively extendable between extended and retracted positions.

Abstract: Apparatus for attachment to a refuse truck for moving a refuse container platform from a ground loading station to elevated, inverted dumping and/or washing stations above the truck bed includes a pair of elevating assemblies connected to the sides of the truck body and to the container platform that act substantially in unison to move the container platform relative to the truck bed. Each elevating assembly includes an arm assembly connected to the container platform and pivoted by a hydraulic cylinder. Each arm assembly has first and second arms pivotally connected to one another. In operation, the second arm is pivoted relative to the first arm into a vertical position to move the container platform from ground level to a position above the truck bed, then both arms pivot together to move the container platform horizontally forwardly over the truck bed but not substantially higher off the ground.
