A bed status system includes a patient support apparatus having a status, a location unit configured to provide a location to the patient support apparatus, and a bed status module coupled to the location unit and the patient support apparatus to receive the status and the location. More particularly, the present invention provides a method for identification, classification and prediction of protein structures. Instead of being custom fitted by a CPAP interface specialist, the patient is given multiple CPAP interfaces to try and select the CPAP interface most desirable to the patient. Upon detection of a load change, the transducers are engaged in an active mode to actively scan the impact area to determine the location and size of any resulting damage region. Where the light transmissive carrier comprises a thermo formable material the method can further comprise heating and vacuum molding the carrier such as to form an array of hollow features configured such that a respective feature corresponds to a respective light emitter and is capable of housing a respective light emitter.
