The system in one embodiment relates to tightly integrating parameter estimation, symbol hypothesis testing, decoding, and rate identification. The device of the invention is useful for lifting and moving any object which has a pair of spaced apart wheels but is particularly adapted for the lifting and transporting of hospital beds. The first solar cell portion includes at least one junction and at least one solar cell contact on a backside of the first solar cell portion. The isolation structures are formed by modular implant and etch processes that do not include significant thermal processing or diffusion of dopants so that the resulting structures are compact and may be tightly packed in the surface of the substrate. The first wick member can be engaged at an angle with the second wick member.
