  • Publication number: 20240143167
    Abstract: An array of bit cells is programmed with user data, each row including a corresponding word line and each column including a corresponding column line. The array includes a plurality of differential PUF bits, each having a first and second bit cell programmed with user data. A first set of sense-amplifiers outputs a set of data bits of the user data, and a second set of sense-amplifiers outputs a set of differential bits, each differential bit based on a differential current between two columns lines of the selected column lines corresponding to the first and second bit cells of a corresponding differential PUF bit along the selected word line. A potential PUF bit generator outputs a set of potential PUF bits based on the set of data bits of the user data from the first set of sense-amplifiers and the set of differential bits from the second set of sense-amplifiers.

  • Patent number: 11887712
    Abstract: Technologies are provided for classifying detected events as labeled event combinations. Input data for different combinations of detected events are received at a server system, and each combination of detected events is processed at the server system. Processing can include classifying that combination of detected events at a classifier to map that combination of detected events to a probability of an increased insulin delivery demand or a probability of a decreased insulin delivery demand, and labeling each classified combination of detected events with a label to generate a corresponding labeled event combination that has the probability of the increased insulin delivery demand or the probability of the decreased insulin delivery demand. Each labeled event combination can be stored in storage as a database of labeled event combinations, and selected ones of the labeled event combinations can be processed at a client application to generate an output result.

    Abstract: A magnetoresistive random access memory (MRAM) array includes a data array and a sensor array. Each MRAM cell includes a Magnetic Tunnel Junction (MTJ). Each MRAM cell of the data array stores a data bit. A first and second column of the sensor array are connected to form a sensor column which includes sensor cells, each formed by a first MRAM cell in the first column together with a second MRAM cell in the second column along a same word line. Only one of a first MTJ of the first MRAM cell or second MTJ of the second MRAM cell is used as an MTJ of the sensor cell, and drain electrodes of select transistors of the first and second MRAM cells are electrically connected. Read circuitry provides read data from the data array and a sensor output indicative of a rupture state of an MTJ of the sensor array.

  • Patent number: 11839744
    Abstract: Techniques related to automatically generating a super bolus may include determining an amount of an augmented meal bolus to be delivered to a patient for regulating the patient's glycemic response to a meal. The amount of the augmented meal bolus may exceed a sufficient amount for counteracting a glucose level increase caused by the meal. In some embodiments, the techniques may further include determining a duration of a postprandial reduction period during which basal dosage deliveries to the patient are to be reduced. In some other embodiments, the techniques may further include delivering the augmented meal bolus to the patient prior to determining whether or not to cause reduction of basal dosage deliveries. More specifically, a glucose level of the patient may be obtained after delivery of the augmented meal bolus, and the obtained glucose level may be used to determine whether to reduce basal dosage deliveries.

  • Patent number: 11712520
    Abstract: Medical devices and related systems and operating methods are provided. A method of operating an infusion device capable of delivering fluid influencing a physiological condition to a patient involves obtaining an event indication, such as a meal indication, determining an initial bolus amount based on the event indication, and determining predicted values for the physiological condition of the patient during a time window into the future based at least in part on the initial bolus amount. When the predicted values violate a threshold during the time window, the control system identifies an adjusted bolus amount that results in the predicted values for the physiological condition satisfying the threshold during the time window from within a search space defined by the initial bolus amount and operates an actuation arrangement of the infusion device to deliver the adjusted bolus amount of the fluid to the patient.
