A modular picket fence including a pair of vertical separated posts and adapted to be secured to a suitable support surface. A free running clock circuit generates a temperature compensated clock that does not require a synch signal from external to the chip. From graphic commands, a first sequence of graphic commands is determined. Alternatively, a gas emitting tape is positioned under a micro-crack cut line and applies a force against the brittle material along the micro-crack cut line, therein propagating the micro-crack through the thickness of the material and completely separating the brittle material along the micro-crack cut line. A control terminal of the multi-selection switch is used to receive a control signal so as to select a coil segment for connection to the output terminal. Image data associated with the IR beacon is identified using the time signature.
