A method for estimating the position and the speed of a target with a radar is provided. The thermoelectric device includes first and second electrodes, a first leg, a second leg, and a common electrode. In some embodiments, anodes are interspersed among cathodes, and are electrically separated from the cathodes, with portions of cathode material attached to the welding area of the anode. A content selection command such as a number key input of the remote controller allows immediate and automatic updating of the primary display area to include a desired content item that is associated to the command. Generally described, the lifting device includes a mast separable into a plurality of sections and a pulley supported by a first section of the mast. In one implementation thereof, a device for transferring drive force to a transported object transfers drive force to one side in the width direction, which is perpendicular to the transporting direction.
