1. A method of determining glucose trend information, comprising:
- receiving a signal associated with a monitored analyte level from an in vivo analyte sensor;
retrieving a predetermined number of stored signals associated with the monitored analyte level and received from the analyte sensor;
determining glucose trend information including a rate of change of the monitored analyte level indication based on the received signal and the retrieved predetermined number of stored signals, the predetermined number of stored signals not exceeding a preset error factor tolerance level such that no more than a fixed number of the stored signals are determined to be corrupt; and
updating a prior trend information based on at least a portion of the retrieved predetermined number of stored analyte level signals.

8. An apparatus, comprising:
-
a communication unit to receive an analyte level signal from an in vivo analyte sensor; and a data processing unit coupled to the communication unit, the data processing unit configured to retrieve a predetermined number of stored analyte level signals received from the analyte sensor, determine a trend information including a rate of change of the analyte level indication based on the current analyte level signal and the retrieved predetermined number of stored analyte level signals, the predetermined number of stored analyte level signals not exceeding a preset error factor tolerance level such that no more than a fixed number of the stored analyte level signals are determined to be corrupt, and update a prior trend information based on at least a portion of the retrieved predetermined number of stored analyte level signals. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)

17. A method of determining glucose trend information, comprising:
-
receiving a signal related to a monitored analyte level from an in vivo analyte sensor; retrieving at least one stored signal related to the monitored analyte level received from the analyte sensor; determining a calibration scaling factor; applying the determined calibration scaling factor to the received signal and to the retrieved at least one stored signal to generate scaled data, wherein the generated scaled data includes retrieved data and the received signal adjusted with the calibration scaling factor; and determining glucose trend information based on the generated scaled data such that the accuracy of the determined glucose trend information is greater than the accuracy of glucose trend information based on the received and retrieved signals before the calibration scaling factor is applied. - View Dependent Claims (18, 19, 20, 21, 22)
