The present invention is an improvement to a non-invasive blood pressure sensing device and method. The present invention is an improvement that includes a transducer (26) with an associated memory or memories (28A) for storing data such as sensor characteristics and history information. In a preferred embodiment, the stored information includes transducer offsets and gains, date code, serial number, model type, usage counter, time stamp of the last test of the device, motor characteristics and one or more checksums. The stored data is used by the device (10) for several purposes including calibration, generation of indications such as component expiration indications and test needed indications, automatic identification of appropriate algorithms for control and data manipulation, service and billing. |
