  • Patent number: 10431342
    Abstract: A method, system and related computer program product for tracking the probability of hypoglycemia from routine self-monitoring of blood glucose (SMBG) data in patients with diabetes. A specific bivariate probability distribution of low BG events based jointly on the Low BG Index (LBGI) and the Average Daily Risk Range (ADRR) is used to predict hypoglycemia probability of occurrence from inputted SMBG data. The SMBG data is retrieved from a series of SMBG data of a patient available from the patient's glucose meter and allows tracking of the probability for future hypoglycemia over a predetermined duration, e.g., a 24 or 48 hour period. The tracking includes presentation of visual and/or numerical output, as we construction of hypoglycemia risk trajectories that would enable warning messages for crossing of predefined thresholds, such as 50% likelihood for upcoming hypoglycemia below 50 mg/dl.

  • Patent number: 10411723
    Abstract: A Dynamic Triggering and Sample Engine (DTSE) that detects a first trigger received on a trigger input terminal that triggers a series of analog-to-digital conversions to be completed by an analog-to-digital converter circuit. The DTSE then determines a first sequence configuration stored in a sequence configuration table that is associated with the first trigger, causes a first analog-to-digital conversion to be performed using the first sequence configuration; causes a first analog-to-digital conversion result value to be stored in a sequence result table; and outputs an interrupt to a processor indicating that the first analog-to-digital conversion result value is available in the sequence result table. The interrupt is output from the DTSE before all remaining analog-to-digital conversions in the series are completed. In response to receiving the interrupt, the processor reads the analog-to-digital result value from the sequence result table via a bus.
