Systems and methods for processing sensor data and self-calibration are provided. In some embodiments, systems and methods are provided which are capable of calibrating a continuous analyte sensor based on an initial sensitivity, and then continuously performing self-calibration without using, or with reduced use of, reference measurements. In certain embodiments, a sensitivity of the analyte sensor is determined by applying an estimative algorithm that is a function of certain parameters. Also described herein are systems and methods for determining a property of an analyte sensor using a stimulus signal. The sensor property can be used to compensate sensor data for sensitivity drift, or determine another property associated with the sensor, such as temperature, sensor membrane damage, moisture ingress in sensor electronics, and scaling factors.

An activity management system is configured to allow users to access multimedia content where the multimedia content is divided into segments. While a user is viewing or interacting with the multimedia content, the user can submit one or more activities (e.g., comments, questions, replies, or reactions) using an interface. The system is operable to electronically link the activity provided by the user with the particular segment of multimedia content in which the activity was captured by the system. The system is also configured to throttle the number of activities that are displayed to a user for any given segment based on (1) viewers linked to the user (e.g., groups, social media groups, etc.), (2) viewers that influence the user, (3) viewers selected by the user, (4) viewers that cause the user to be engaged with the multimedia content, and (5) a threshold number of activities set by the viewer or the system.

Methods and systems for a detecting an intruder near or within a vehicle are disclosed. Specifically, a method to detect and identify a person near or within a vehicle as an authorized or an unauthorized user is provided. In the event an unauthorized user is detected within a vehicle, the system may take a number of actions. In one embodiment, the actions comprise providing notice to one or more authorized users of the vehicle, disabling the vehicle, notifying emergency personnel or police, and emitting a visual or audio alarm.
