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.
What is claimed is: 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 tra
What is claimed is: 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. 2. The method of claim 1, wherein the receive mode occurs five minutes. 3. The method of claim 1, further comprising the step of: activating an alarm if the transmitted message is not received by the characteristic monitor after a predetermined period of time. 4. The method of claim 1, further comprising the step of: entering the receive mode at the next anticipated transmission time if the transmitted message is not received by the characteristic monitor. 5. The method of claim 1, further comprising the step of: expanding the receive mode to cover all time windows until the next message is received if the transmitted message is not received by the characteristic monitor. 6. The method of claim 1, wherein the pseudo-randomly selected time window is one second. 7. The method of claim 1, wherein the step of transmitting the message occurs after the sensor initializes. 8. The method of claim 7, wherein the sensor initializes in five minutes. 9. The method of claim 7, wherein the message is transmitted in a pseudo-randomly selected time window within 128 seconds following the sensor initialization. 10. The method of claim 1, wherein the step of transmitting the message occurs while the sensor initializes. 11. The method of claim 1, wherein the message is between 100 ms to 150 ms in length.
