An image of a check that is in the field of view of a camera is monitored prior to the image of the check being captured. The present invention supply tensile stress in the channel width direction of a MOS transistor, so as to improve performance of PMOS andor NMOS transistors. These chambers have a generally flat two-dimensional shape in its uninflated and unfolded configuration. When in the closed position, a second end of each bar is preferably engaged in a bracket of the frame, which provides added support for the bar and prevents inadvertent opening thereof. In the case where the load is being disconnected from a first AC source and connected to a second AC source, the volt-seconds of the load can be measured andor calculated during disconnect, in order to delay connection of the load to the second AC source by an amount sufficient to prevent saturation of magnetic devices and thereby ensure volt-second synchronization of the sources.
