A battery-operated electronic device, such as, e.g., a continuous glucose monitoring (CGM) transmitter, has a switch disconnect circuit that reduces battery discharge while the device is stored and/or in 'shelf mode.' The device has two externally-accessible activation pads each configured to contact a same electrical conductor positioned in packaging for the device that causes the switch disconnect circuit to disconnect the battery from device electronics while the device is in the packaging. Upon removal of the device from the packaging, the two activation pads no longer contact the electrical conductor, causing the switch disconnect circuit to automatically connect the battery to the device electronics. Methods of reducing battery discharge in a battery-operated electronic device and other aspects are also described.

An analyte monitor includes a controller including a processor coupled to a memory. The memory has instructions stored therein that, when executed by the processor, cause the controller to: provide a working electrode voltage to a working electrode of an analyte sensor; selectively provide a first counter electrode voltage and a second counter electrode voltage to a counter electrode of the analyte sensor; and provide a guard ring voltage to a guard ring associated with the working electrode. The analyte monitor further includes a current measurement circuit coupled to the controller and configured to measure current flow to the working electrode and a reference resistor electrically coupled between the working electrode and the guard ring associated with the working electrode. Other monitors, systems, sensors, and methods are disclosed.

A test sensor for determining an analyte concertation in a biological fluid comprises a strip including a fluid receiving area and port-insertion region. A first row of optically transparent and non-transparent positions forms a calibration code pattern disposed within a first area of the port-insertion region. A second row of optically transparent and non-transparent positions forms a synchronization code pattern disposed within a second area of the port-insertion region. The second area is different from the first area. The synchronization code pattern corresponds to the calibration code pattern such that the synchronization code pattern provides synchronization of the serial calibration code pattern during insertion of the port-insertion region into the receiving port of the analyte meter.

A portable data-management system may be easily employed with multiple processing devices by eliminating the need to pre-install additional programs, agents, device drivers, or other software components on the hosts. A portable storage device contains software for a data-management application, which receives and processes test data from a meter that measures an analyte. The portable device may employ an interface protocol that makes the portable device immediately compatible with different operating systems and hardware configurations. Once the portable device is connected to the host, the data-management application can be automatically launched. The convenience and portability of a data-management system may be enhanced by integrating advanced data processing and display features with the portable device. The users may access some advanced presentations of health data without having to launch the data-management application on a separate host.

A system and method is described for rapid charging and power management of a battery for a meter. A charger component is operably associated with the meter and is capable of executing a rapid charge algorithm for a rechargeable battery. The algorithm includes monitoring for a connection to an external power source and implementing a charging routine of a battery at a first charge rate and then at a second charge rate. The second charge rate is lower than the first charge rate. A temperature rise in the rechargeable battery due to the first charge rate has a negligible heat transfer effect on the fluid sample. The meter can also include a power switch for controlling current flow to a battery fuel gauge. The power switch is open when the meter enters into a sleep mode. The state of battery charge is determined after the meter exits the sleep mode.
