A three-dimensional imaging system to reduce detected ambient light comprises a wavelength stabilized laser diode to project imaging light onto a scene, an optical bandpass filter, and a camera to receive imaging light reflected from the scene and through the optical bandpass filter, the camera configured to use the received imaging light for generating a depth map of the scene. The latter can be closed with a lowerable bottom door. The decorative stones are matched to a color or colors of the animal. A capacitor bottom plate is formed to contact the storage cell contact pads, then the dielectric layer is etched a third time using the liner and the bottom plate as an etch stop layer. Each rule specifies at least how to form the analytic result from one or more analytic measurements.
