Patent ID: 7602310

Claim:
A telemetered characteristic monitor system for monitoring a characteristic of a user, the system comprising: a sensor for producing a signal indicative of the glucose level in the body of a user; and a transmitter device including: a housing; a sensor interface on a first semiconductor chip within the housing coupled to the sensor to provide an interface between the sensor and the transmitter device; processing electronics on a second semiconductor chip within the housing coupled to the sensor interface to process the signals from the sensor; data formatting electronics on a third semiconductor chip within the housing and coupled to the processing electronics for converting the signals processed by the processing electronics into a stream of data having a predetermined format; and a transmitter coupled to the data formatting electronics for wirelessly transmitting the stream of data to a remotely located data receiving device that is configured to be worn on the user's body and includes a tactile indicator for providing to the user at least one of a reminder and an indication of a condition of said characteristic monitor system, said characteristic monitor system being calibrated by inputting a calibrating glucose reading into said remotely located data receiving device.
