Abstract: A system analyzes user activity data generated by computing devices associated with a plurality of users in a messaging system to extract a random user from the plurality of users. Based on determining that user activity data associated with the random user comprises a consistent pattern, a cluster associated with the consistent pattern is generated and the random user is added to the cluster. Then user activity data for the other users in the plurality of users is analyzed to determine whether user activity data for each of the other users comprises a similar pattern as the generated cluster. Each user that is determined to be associated with user activity data comprising a similar pattern as the consistent pattern of the generated cluster is added to the generated cluster and user activity data associated with each user added to the generated cluster is removed from the user activity data.

Abstract: A compact wearable modular multifunctional inhalation and detection device. The device includes a housing with at least one port; a removable cartridge module adapted to seat within the housing, the cartridge module including a removable cylindrical cartridge adapted to seat within a cartridge housing. The cartridge includes a source of inhalant, a port and a heating element for heating the inhalant. A permanent magnet and/or an electromagnet is mounted within the cartridge housing to secure the cartridge to the cartridge housing via the adapter ring whereby the cartridge is pneumatically coupled to an inlet chamber in the mouthpiece housing. Multiple sensors are coupled to the air switch and provide data to an onboard processor. The processor executes software to provide a useful output data regarding inhalation activity. In an alternative embodiment, the device housing is adapted to retain a cartridge with a sensor adapted to detect and address airborne pathogens.

Abstract: A compact modular multifunctional inhalation device including a housing having an inlet port and an outlet port; a removable cartridge module adapted to seat within the housing, the cartridge including: a tray within the cartridge for holding a solid inhalant, a heating element mounted within the cartridge above and through the tray for heating the inhalant; and a removable modular electronic circuit adapted to seat within the housing to provide electrical current to the heating element. The heating element is a coil mounted within a chamber in thermal proximity to the solid inhalant. A quartz rod is mounted within the coil. A plunger is mounted within the cartridge to translate therein and compact the solid inhalant. In an alternative embodiment, dual channels and outlet ports are mounted in communication with an inlet port. In another embodiment, the cartridge is a split chamber cartridge with a split plunger mounted therein.

Abstract: An A/B testing system is adapted to include a user correlation engine and an A/B test exposure module. The A/B testing system includes an A/B test server that provides at least one A/B test to users of a product and collects and analyzes results of the A/B test(s) to determine an outcome. The user correlation engine clusters the users into behavioral clusters based on an activity level of the users with the product. The behavioral clusters include at least high engagement users and lower engagement users. The results of the A/B test(s) for the high and lower engagement users are correlated to identify correlations between at least one high engagement user and at least one lower engagement user. The A/B test exposure module allocates the A/B test exposures to at least the high engagement users based on the identified correlations to optimize the A/B test exposures across the A/B test(s).

Abstract: An engagement tracking system monitors user interactions with media items to calculate an engagement score of the media item. The engagement tracking system may be or include a group of one or more server machines configured to detect an exposure of a client device to a media item maintained by the engagement tracking system. In response to detecting the exposure of the client device to the media item, the engagement tracking system tracks a location of the client device based on access requests to location based media items. The engagement tracking system may thereby monitor client devices exposed to the media item in order to calculate an engagement score of the media item.

Abstract: A location based measurement system monitors user interactions with media items, and visitation data to physical locations, to calculate an engagement score of the media item, wherein the engagement score serves as an indication of a “lift” incited by the media item on a population of users exposed to the media item. The location based measurement system may be or include any instrumentality or aggregate of instrumentalities operable to compute, process, store, display, generate, communicate, or apply various forms of data for geo-fencing, control, or other purposes.

Abstract: System and method for infectious disease prevention includes transmitting, via a server, a facility credential associated with a facility configured to identify a user operating on an application deployed by server from a mobile computing device. The server receives a user identification test code (UITC) associated with a status of an infectious disease of the user. The server then generates a two-dimensional code associated with the facility credential based on the UITC. The server determines if the two-dimensional code is valid for permitting access to the facility based on the status of the infectious disease. Thereafter, the server activates the two-dimensional code on the mobile computing device for a predetermined period of time. A gatekeeper device responds to the two-dimensional code from the mobile computing device and then permits the user access to the facility within the predetermined period of time based on the facility credential and the two-dimensional code.
