The present invention relates to a tubular fabric for receiving an underwire in a garment such as a bra. The physiological monitoring system may contain several sensors including a pulse oximeter to detect oximetry and pulse rate, a microphone to detect snoring sounds, and a position sensor to detect head position. The housing includes a latch beam that is deflectable between a latched state and an unlatched state. The one-time programmable devices can be programmed to decouple flawed arrays of reference bit cells from the merged reference node or to select between redundant arrays of reference bit cells for coupling to the reference node. The three signals are aligned with respect to the clock edge to center the intermediate data signal on the clock edge.
