Abstract: A pressure belt comprising a flexible belt, and a flat pack assembly removably attached to the flexible belt, wherein each flat pack assembly comprises at least one sensing element. Further, each flat pack assembly also comprises a memory component associated with the sensing element thereon, wherein the memory component houses data specific to the corresponding sensing element. Unlike prior art structures, each flat pack assembly is individually removable. Therefore, if one sensing element malfunctions, it may be replaced by removing the flat pack assembly comprising the malfunctioning sensing element and swapping it out for a flat pack assembly comprising an operable sensing element. This is an improvement over the prior art as it eliminates the need for replacing and recalibrating the entire pressure belt when one sensing element malfunctions, which can be both time consuming and costly.
