Abstract:
The invention is a fully enclosed sample analysis chamber with two halves which may be opened and closed to allow insertion of a sample and closing to keep out ambient light. The upper half has a downward-facing hemispherical dome, attached by hinges to the lower half which holds the planar analysis surface. The dome is provided with lighting means such as RGB LEDs disposed so as to provide uniform illumination of controllable color and intensity to the planar analysis surface when the device is closed. Image processing is carried out by camera under exactly reproducible conditions including use of automatic gain correction and area spectroscopy.
Abstract:
The present invention provides a system for determining power output and propulsion efficiency of a user's limb during limbed propulsion; the system comprising: (a) at least two or more accelerometers to measure the acceleration of the limb in at least two substantially orthogonal planes, (b) a processor means to calculate the power output generated by the limb to derive a limb propulsion efficiency measure, and (c) a transmission means to send the limb power output and limb propulsion efficiency metrics to a receiving device; and wherein the system is wearable on the user's limb.
