510(k) Premarket NotificationVitalSense 0Mini Mitter Co, Inc.11.1.4Device description11.1.4.1 Functions of the deviceVitalSense is a compact, ambulatory, physiological data logger. VitalSense may beattached to the belt or worn in a shirt pocket. Up to ten telemetric sensors may be used with asingle VitalSense logger. The device senses and records physiological data and displays the dataon its LCD screen. Recorded data may be transferred later to a PC for display and conversion forexport to other programs.11.1.4.2 Basic scientific conceptsThe device acquires and logs digital data whose values represent the amplitudes ofphysiological signals. Currently available wireless sensors (see Addendum 1) sense temperatureas the physiological signal. The scientific concepts and technologies that are used to sense thesignals are summarized in Table 13.TABLE 13.
