1. A measurement module for analyte testing comprising:
- a housing having a test strip receptacle and a connector portion, wherein the connector portion provides a direct connection between the measurement module and a processing device;
a glucose measurement circuit for determining the amount of glucose present in a sample;
at least one optoisolator for transmitting data across a power isolation barrier between the measurement module and the processing device;
an isolated power module; and
a transformer-coupled power transfer circuit that bridges the power isolation barrier and thereby transfers isolated power from a power source to the isolated power module.

Abstract
A measurement module for glucose testing includes a glucose testing measurement module housing, a test strip receptacle formed in the housing, and a connector portion formed in the housing and shaped to permit mechanical removable attachment of the housing to a hand-held computer. Electronics determine the amount of glucose present in a sample of body fluid, when the test strip is positioned in the receptacle and the body fluid is placed on a test strip, and communicate the glucose amount to the hand-held computer via the connector portion.

8. An analyte monitoring apparatus, comprising:
-
a measurement module having an analyte test sensor receptacle, a glucose measurement circuit to determine the amount of glucose present in a sample, an isolated power module, and a connector portion; and a processing device coupled with the connector portion of the measurement module to form an integrated, hand-held unit, wherein the processing device includes a power source; a power isolation barrier between the power measurement module and the hand-held processing device; a data isolation circuit having at least one optoisolator pair to transmit data across the power isolation barrier; and a transformer-coupled power transfer circuit that bridges the power isolation barrier and thereby transfers isolated power from the power source in the processing device to the isolated power module in the measurement module. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
