Analog-valued floating-gate transistors are used as trimmable circuit components for modifying andor controlling the gain, phase, offset, frequency response, current consumption, andor transfer function of signal pathways in parallel andor serial processing circuits in radio frequency, analog, or mixed-signal integrated circuits. The control system may control one or more devices within a vehicle. The pixel data that defines the overlapping part includes mask data that identifies pixels of the overlapping part that are to be included in the image. The closed position protects contents of the file folder, while the opened position allows access to the contents of the file folder. The upper half element has an exposed surface for receiving a corner portion of the rectangular member to minimize shifting and other movement of the rectangular member.
