    Abstract: In a first embodiment, electrodes are coupled to a surface at first, second, and third locations, the first location being further from the third location than from the second location. Impedance is measured at distinct frequencies between pairs of the electrodes. As a result, impedance is measured at differing regions below the surface, one region being deeper below the surface than the other region. In a second embodiment, a microfluidic device carries out an analysis. The analysis may be within a flexible patch adhered to a surface, or may be in a solid device implanted in a body of liquid surrounded by tissue. The analysis may involve pumping a fluid or may involve drawing an analyte electrophoretically through a microfluidic channel.

    Abstract: A system for managing power consumption of a handheld diabetes management device and limiting effects of temperature on operations performed by the handheld diabetes management device comprises a blood glucose measuring module, a temperature sensing module, and a power management module. The blood glucose measuring module selectively measures blood glucose in a blood sample and generates a status signal indicating a status of operation of the blood glucose measuring module. The temperature sensing module senses an internal temperature of the handheld diabetes management device and estimates an ambient temperature external to the handheld diabetes management device. The power management module deactivates one or more components of the handheld diabetes management device based on the status of operation of the blood glucose measuring module when the internal temperature of the handheld diabetes management device exceeds a threshold temperature. The power management module deactivates the blood glucose measuring module when the ambient temperature is greater than a first predetermined threshold or less than a second predetermined threshold.

    Abstract: A system is provided for monitoring analyte in a host, including a continuous analyte sensor that produces a data stream indicative of a host's analyte concentration and a device that receives and records data from the data stream from the continuous analyte sensor. In one embodiment, the device includes a single point analyte monitor, from which it obtains an analyte value, and is configured to display only single point analyte measurement values, and not any analyte measurement values associated with data received from the continuous analyte sensor. Instead, data received from the continuous analyte sensor is used to provide alarms to the user when the analyte concentration and/or the rate of change of analyte concentration, as measured by the continuous analyte sensor, is above or below a predetermined range. Data received from the continuous analyte sensor may also be used to prompt the diabetic or caregiver to take certain actions, such as to perform another single point blood glucose measurement. In another embodiment, the device provides for toggling between two modes, with one mode that allows for display of glucose concentration values associated with the continuous glucose sensor and a second mode that prevents the display of glucose concentration values associated with the continuous glucose sensor.

    Abstract translation: 提供了一种用于监测主机中的分析物的系统，包括产生指示宿主分析物浓度的数据流的连续分析物传感器，以及从连续分析物传感器接收并记录来自数据流的数据的设备。 在一个实施例中，该装置包括单点分析物监测器，其从其获得分析物值，并且被配置为仅显示单点分析物测量值，而不是与从连续分析物传感器接收的数据相关联的任何分析物测量值。 相反，当通过连续分析物传感器测量的分析物浓度和/或分析物浓度的变化速率高于或低于预定范围时，来自连续分析物传感器的数据被用于向用户提供警报。 从连续分析物传感器接收的数据也可用于促使糖尿病患者或护理者采取某些措施，例如进行另一单点血糖测量。 在另一个实施方案中，该装置提供两种模式之间的切换，其中一种模式允许显示与连续葡萄糖传感器相关联的葡萄糖浓度值，以及防止显示与连续葡萄糖传感器相关联的葡萄糖浓度值的第二模式。
