Various embodiments of a bonding machine structured and programmed for bonding or laminating one or more materials is disclosed. At least one of front and back surfaces is formed as a progressive-power surface whose dioptric power varies depending upon a position thereon. Attitude readout errors bias due to periodic gimbal motions is determined in each IMU along each gyroscope attitude axis. A first heat sensing circuit is located on the first side of the first channel and a second heat sensing circuit is located on the second side of the channel, opposite the first side and facing the first heat sensing circuit.
