The disclosed invention provides apparatus, systems, and methods for orientating an object in an enclosed area using a magnetic dipole deployed in the enclosed area and thereafter applying an external rotating magnetic field for applying a rotational force to the dipole along one or more selected axis. Peer discovery, based on direct peer to peer discovery between two mobile nodes can be somewhat limited, e. The metal substrate is removed from the master surface, and at least one electronic device is formed on the seed layer of the metal substrate. The control commands give consideration to the run times of the boilers. The devices are removeably mounted to mesh tissue repair implant devices to manipulate the devices into position and provide for secure fixation about the periphery of such mesh implant devices by providing guide structures such as grooves for directing and positioning a surgical tacking instrument. In a fourth embodiment, the secondary substrate is a flex circuit having a mounting portion secured to the second surface of the transparent substrate and a backing portion bent over adjacent to the back surface of the image sensor chip.
