channel the time domain is divided into several recurrent timeslots of fixed length one for each sub channel a portion e g a digital sample byte or data block of sub channel 1 is transmitted during timeslot 1 a portion e g a digital sample byte or data block of sub channel 2 during timeslot 2 etc in some embodiments one time division multiplexed frame comprises one timeslot per sub channel and a synchronization channel furthermore in some embodiments one time division multiplexed frame sometimes comprises an error correction channel before the synchronization after the last sub channel error correction and synchronization channels the cycle repeats with a new frame starting with the second portion e g digital sample byte or data block from sub channel 1 etc if done sufficiently and quickly the receiving devices will not detect that some of the circuit time was used to serve another logical communication path the multiplexer processes and routes signals received from a plurality of analyte sensors in some embodiments the sensors are electrochemical analyte sensors the electrochemical analyte sensors are exposed to and react with the sample to be assayed and generate an electrical signal e g a potential a current a conductivity that is a function of the chemical activity of the analyte being measured for example in some embodiments the electrochemical analyte sensor generates a potential that is a function of the amount or concentration of the analyte in the sample e g a potentiometric sensor while not limited in the types of sensors that may be used it is contemplated that the device comprises microfabricated.
