Telemetered characteristic monitor system and method of using the same
First Claim
1. A method of synchronizing a transmitter connected to a sensor producing a signal indicative of a characteristic of a user with a remotely located characteristic monitor, the method comprising:
- giving a unique ID code to the transmitter; and
transmitting a message from the transmitter to the remotely located characteristic monitor in pseudo-randomly selected time windows based on the unique ID code of the transmitter,wherein the pseudo-randomly selected time windows are established by utilizing the unique ID code of the transmitter to set up a table of transmission time windows that defines an order in which the transmitter will transmit the message;
wherein the message includes a message count number which indicates where in the sequence of time windows the transmitter is currently transmitting;
setting up a corresponding table of time windows in the characteristic monitor utilizing the unique ID code of the transmitter;
synchronizing the characteristic monitor with the transmitter using the received message count number to locate current position in the corresponding table of time windows; and
determining when the characteristic monitor must be in a receive mode to acquire a next message.

Abstract
A telemetered characteristic monitor system includes a remotely located data receiving device, a sensor for producing signal indicative of a characteristic of a user, and a transmitter device. The transmitter device includes a housing, a sensor connector, a processor, and a transmitter. The transmitter receives the signals from the sensor and Tirelessly transmits the processed signals to the remotely located data receiving device. The processor coupled to the sensor processes the signals from the sensor for transmission to the remotely located data receiving device. The data receiving device may be a characteristic monitor, a data receiver that provides data to another device, an RF programmer for a medical device, a medication delivery device (such as an infusion pump), or the like.
