A method for enabling engagement between a first application on a device and a set of contacts associated with a second application on the device, including: receiving, at the first application, an authentication token from the second application, wherein the authentication token is configured for providing an authentication pass to a server when delivered thereto by the first application, thereby allowing the first application access to a set of messaging functionalities available at the server; delivering the authentication token to the server; upon the authentication token having been verified by the server, connecting, using a communication platform, to the server, wherein the communication platform includes communication functionalities configured for enabling communication with other devices; and communicating with contacts of a set of contacts associated with the second application using, via the communication platform, at least one messaging functionality of the set of messaging functionalities.

Systems and related methods facilitating interactions between a merchant device, a central system and a consumer device are discussed herein. Wallet identifying data may be used to secure messages between the consumer device and the merchant device over a wireless link. For example, the merchant device may include circuitry configured to wirelessly receive the wallet identifying data from a consumer device and to transmit the wallet identifying data to the central system. In response, consumer identifying data associated with the wallet identifying data may be received by the merchant device from the central system. In some embodiments, the consumer identifying data may be associated with a unit of location, such as a dine-in location at a restaurant, to facilitate consumer service.

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.

The vehicle control system/method for adapting a control function based on a user profile may comprise: a gesture recognition module; a user profile module; a function control module; a processor; a non-transitory storage element coupled to the processor; encoded instructions stored in the non-transitory storage element, wherein the encoded instructions when implemented by the processor, configure the system to: identify a user; retrieve a user profile for the identified user; receive at a gesture recognition module, an input indicating a gesture from the user; identify a control function request corresponding to the gesture input; send a verification of the control function request; and receive at a function control module characteristics parsed from the user profile that effect the control function request by the user profile module to adapt a control function command for an adapted control function output by the function control module.

A user-replaceable e-liquid reservoir for dispensing e-liquid, the reservoir being inserted into, or otherwise attached to, a portable, personal e-cigarette device and engaging with an electrical or electronic pump fluid transfer system in the device, the device including: an electrical or electronic pump, being configured to transfer e-liquid from the e-liquid reservoir to an atomizing unit in the device, the pump delivering a pre-defined or variable quantity of e-liquid from the reservoir; and in which the reservoir is not user-refillable.

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 to build containers of uncategorized items are described. In some example embodiments, the methods and systems collect information from titles of items available for purchase within a network-based publication system, generate a title for a container of uncategorized items available for purchase within the network-based publication system that is based on the collected information, and associate two or more uncategorized items available for purchase within the network-based publication system to the container based on a comparison of titles of the two or more uncategorized items and the generated title for the container of uncategorized items.

Pre-connected analyte sensors are provided. A pre-connected analyte sensor includes a sensor carrier attached to an analyte sensor. The sensor carrier includes a substrate configured for mechanical coupling of the sensor to testing, calibration, or wearable equipment. The sensor carrier also includes conductive contacts for electrically coupling sensor electrodes to the testing, calibration, or wearable equipment.
