  • Patent number: 10984912
    Abstract: A method and apparatus that for monitoring the physiological state of nutrition of an individual and adaptively analyze that data input to anticipate the individual's nutritional needs. A satiety meter may be employed to analyze a user's profile including nutritional state and determine when and how much a user should consume to prevent the onset of hunger and communicate is to a decision engine. The decision engine may generate and communicate a message to the user via the client device to prescribe prophylactic intake of nutrition to the individual prior to the onset of hunger based on the user's nutrition plan and/or regimen.

  • Patent number: 10955270
    Abstract: A physiological monitor gauge panel defines parameters to display on a physiological monitor via corresponding gauges. Gauge faces depict a range of parameter values for each of the parameters. An indicator designates a position on each gauge face corresponding to the current parameter value within the range of parameter values. The indicated position on each of the gauges is at the mid-point of each of the gauge faces when each of the parameters is at a nominal value.

  • Patent number: 10856786
    Abstract: A system and method for controlling and monitoring a diabetes-management system through the use of a model that predicts or estimates future dynamic states of glucose and insulin from variables such as insulin delivery or exogenous glucose appearance as well as inherent physiological parameters. The model predictive estimator can be used as an insulin bolus advisor to give an apriori estimate of postprandial glucose for a given insulin delivery profile administered with a known meal to optimize insulin delivery; as a supervisor to monitor the operation of the diabetes-management system; and as a model predictive controller to optimize the automated delivery of insulin into a user's body to achieve a desired blood glucose profile or concentration. Open loop, closed-loop, and semi-closed loop embodiments of the invention utilize a mathematical metabolic model that includes a Minimal Model, a Pump Delivery to Plasma Insulin Model, and a Meal Appearance Rate Model.
