  • Patent number: 11743253
    Abstract: A system for bidirectional device authentication between two computing devices is disclosed. A first processor generates a first random number sequence, performs a first operation on the first random number sequence to determine a first table address, and retrieves a first entry in the first table based on the first table address. The processor also executes a first transformation function on the first entry to generate a first transformed entry, transmits the first random number sequence to the second computing device, receives an encoded entry from a second computing device in response to transmission of the first random number sequence, and decodes the encoded entry to determine a second transformed entry. The first transformed entry matches the second transformed entry, and the first processor performs an update to a dynamic table by replacing each entry of the dynamic table with an associated transformed entry.

  • Patent number: 11741798
    Abstract: An alert is used to inform a user that their blood glucose level has dropped below a threshold (e.g., the user is hypoglycemic) or has increased above a threshold (e.g., the user is hyperglycemic). There is a hierarchy of alerts from lowest priority to highest priority. The alert is communicated by a user device (e.g., a mobile device), which is, for example, a smartphone, smart watch, home automation device, or the like. The alert is modified in order to increase the likelihood that the user receives or acknowledges the alert within a minimal amount of time. An intensity level (e.g., a volume) of an alert is modified based on, for example, whether the user has acknowledged a previous alert. A modality or a sensory channel of an alert is changed if an initial alert does fails to elicit a response from the user.

  • Patent number: 11701037
    Abstract: A method for detecting in-vivo properties of a biosensor. In the inventive method, a sensitivity-to-admittance relation is provided and a raw current in the biosensor is measured. An in-vivo current response is also measured at first and second operating points. A time constant ? is determined by the electrical capacitance C of the working electrode and the electrical resistance RM of the membrane by ?=RM·C. The first and second operating points are selected below and above ?, respectively. An analyte value in a sample of a body fluid is determined by using the raw current and compensating sensitivity drift in the biosensor, which in turn is compensated by using the measured value for the raw current and a corrected value for the sensitivity. The failsafe operation of the biosensor is monitored by using the in-vivo current response measured at the first and second operating points.

  • Patent number: 11686774
    Abstract: A method and device for testing a battery that powers a body-wearable medical device. The battery is contacted via battery contacts and a capacitor is arranged in parallel with the battery contacts. During the battery test, a first capacitor voltage U1 is determined at a first time t1 and a second capacitor voltage U2 is determined at a second time t2 subsequent to time t1. A test current is drawn between time t1 and time t2. t1 is determined by the beginning of drawing the test current and time t2 is determined such that the capacitor voltage at time t2 is in a steady state and is substantially constant while the test current is being drawn. A charging state of the battery is determined from the difference in voltage between U1 and U2 and/or from a time difference between the time t1 and time t2.
