Abstract: The present disclosure describes a multi-analyte sensor system. The system includes a first sensor with a first enzyme for a first analyte, a second sensor with a second enzyme for a second analyte different from the first analyte, a potentiostat, a memory, and a processor communicatively coupled to the memory. The potentiostat applies a first voltage to the first sensor to cause a first current to flow through the first sensor and applies a second voltage to the second sensor to cause a second current to flow through the second sensor. The processor determines, based on the first current, a level of the first analyte and determines, based on the second current, a level of the second analyte.

Abstract: The present disclosure describes a multi-analyte sensor system that detects wear location. The system includes a first sensor, a second sensor, a memory, and a processor communicatively coupled to the memory. The first sensor produces a first signal stream indicating a level of a first analyte, and the second sensor produces first physiological data. The processor determines, based on the first signal stream and the first physiological data, a wear location of the first sensor and makes an adjustment related to at least one of the first sensor or the first signal stream based on the wear location of the first sensor.

Abstract: The present disclosure describes a multi-analyte sensor system that detects artifacts using multiple analytes. According to an embodiment, the multi-analyte sensor system includes a first analyte sensor, a second analyte sensor, and a sensor electronics module. The first analyte sensor produces a first analyte signal stream indicating a level of a first analyte. The second analyte sensor produces a second analyte signal stream indicating a level of a second analyte different from the first analyte. The sensor electronics module detects, based on the first analyte signal stream and the second analyte signal stream, at least one of a compression event or a dip and recover event and in response to detecting at least one of the compression event or the dip and recover event, make an adjustment related to at least one of the first analyte sensor or the first analyte signal stream based on the event.

Abstract: An apparatus includes an analyte sensor, a memory, and a processor. The processor monitors, using the analyte sensor, an analyte of a patient during a time period to obtain measured analyte data for the analyte and monitors other measured sensor data indicative of a physiological state of the patient during the time period. The processor also determines, based on the physiological state of the patient during the time period, expected analyte data for the analyte and determines a correction factor based on the expected analyte data and the measured analyte data. The correction factor is indicative of an error in calibration of the analyte sensor. The processor also determines whether recalibration of the analyte sensor is possible. If recalibration is possible, the processor recalibrates the analyte sensor based on the correction factor, and if recalibration is not possible, the processor recommends, to the patient, to replace the analyte sensor.

Abstract: In one aspect of the invention, a dual-mode infrared/radio frequency (IR/RF) transmitter is secured within a wristband worn by the mother and within an ankle and/or wristband worn by the infant. In a matching mode of operation, IR signals are received by infrared receivers located within the various rooms of the hospital to precisely and automatically determine by proximity that mother and infant are correctly united. In a presence detecting mode, RF signals from the infant's badge are detected by RF receivers located throughout the maternity ward of the hospital or throughout the hospital generally. In a security mode, RF receivers located proximate exits of either of the maternity ward and/or the hospital detect RF signals from the ankle and provide a signal to generate an alarm.
