Abstract: A handheld analyte meter, such as a blood glucose meter, has a measurement module, a rechargeable battery and a charging control to select a maximum charging current to regulate self-heating during recharging that can interfere with analyte tests. Self-heating by the meter can bias temperature measurements made inside the meter that are used to determine whether the temperature is acceptable for testing. Prior to beginning a charging session, the charging control selects the maximum charging current that does not change during the charging session based capacity of a charging source along with a first temperature measured near the battery that is compared with a first temperature range. By selecting the maximum charging current in this manner, the risk of the measurement module preventing a test under high lock-out conditions and the risk of the measurement module allowing a test when low lock-out conditions that are masked is reduced.

Abstract: A computer-implemented diabetes management system is provided that supports enhanced security between a diabetes care manager in data communication with a medical device. The diabetes care manager includes: a first application that operates to request access to a first security role supported by the medical device, where the first security role is associated with a first set of commands for accessing data on the medical device that are defined as a private extension of the communication protocol; and a second application that operates to request access to a second security role supported by the medical device, where the second security role is associated with a second set of commands for accessing data on the medical device that are defined as a private extension of the communication protocol. The second set of commands has one or more commands that are mutually exclusive from the first set of commands.

Abstract: A processor module includes memory having instructions for executing functions of a handheld diabetes management device and a processor that selectively executes the instructions. Battery terminals electrically connect the processor module with a re-chargeable battery. A receptacle is configured in accordance with a universal serial bus (USB) standard. A component is included for communicating information from the handheld diabetes management device to a user or another device. A multiplexer module relays power from the receptacle to a bus voltage node. A first switching device is connected between the bus voltage node and a second voltage node. The component receives power from the second voltage node. A second switching device is connected between the bus voltage node and a third voltage node. The processor module is directly connected to the bus voltage node and to the third voltage node.

Abstract: A handheld diabetes management device includes a blood glucose measurement engine that measures a blood glucose level of a patient. The device includes a physical port that is exposed at an exterior of the device. The device includes a processing module that includes first, second, and third physical interfaces that are internal to the device. The device includes a multiplexing module that alternatively connects the physical port to one of the first, second, and third physical interfaces of the processing module. The processing module selectively operates the first physical interface using first and second modes. When an external host is connected to the physical port, the processing module selectively transfers information based on the blood glucose level to the external host using the first mode. When the external host is connected to the physical port, the processing module selectively provides file access to the external host using the second mode.
