Embodiments of mechanisms for forming a micro-electro mechanical system device are provided. The device may be affixed to the catheter insertion site using an adhesive or fastening band, or through other methods. Because different memory devices may have different CAS latencies, a system CAS latency is selected wherein the system CAS latency is the fastest common CAS latency of each of the plurality of memory devices. An exemplary system and method processes a signal that focuses on a subset of harmonics that are least corrupted by noise, disregards the signal harmonics with low signal-to-noise ratio, and disregards amplitude modulations that are inconsistent with speech. The second segment piece has at least two inner peripheral recesses formed on an inner periphery thereof and at least two outer peripheral recesses formed on an outer periphery thereof. The communications system may also include an interactive voice response system operable to collect information from the device.
