Abstract: An optical device for sensing a presence of an analyte in a person is provided. The optical device includes a light source, an optical stack, and a reader. The light source emits a first light having a first wavelength. The optical stack is placed on a skin of the person. The optical stack includes a sensor material and an optical filter. The sensor material emits a second light having a second wavelength when irradiated with the first light. An optical property of the second light is sensitive to the presence of the analyte. The optical filter is disposed on the sensor material and includes a plurality of microlayers numbering at least 10 in total. The optical filter has different first and second transmittances at the respective first and second wavelengths.

Abstract: Systems and methods include registering use of a virtual certification number (VCN) at a secure entity by receiving, at an external gateway, a registration request comprising an external request code and a primary account number (PAN), wherein the external request code is unique to the secure entity, determining that the external request code is an unregistered external request code, receiving a tokenized PAN based on the PAN, receiving an account identifier by applying the tokenized PAN to a certification mechanism tool application programing interface (API), generating a certification mechanism reference identifier by encrypting a certification mechanism associated with the account identifier and the tokenized PAN, updating a database to associate the certification mechanism reference identifier with the external request code, and transmitting, via the external gateway, a registration authentication to an external entity, the registration authentication comprising the external request code.

Abstract: Systems and methods for triggering a virtual certification number (VCN) generation for use at a source include receiving a VCN generation request from an external entity, the VCN generation request comprising an external request code, external risk signals, and one or more source data for the source, verifying a registration authentication of an account associated with the external request code by comparing the external request code to a database entry, identifying a certification mechanism reference identifier associated with the external request code based on verifying the registration authentication, generating a risk authentication based on a risk analysis conducted using the external risk signals and the external request code, identifying a source identifier based on the one or more source data, and generating the VCN based on the certification mechanism reference identifier and the source identifier.

Abstract: Configurations for geographical targeting for managing content of campaigns are disclosed. In one example, the subject technology provides a user interface including controls for enabling selection of targeting criteria by a content sponsor. The user interface includes a campaign tool for receiving input on campaign details to be executed by a content delivery system. The campaign tool includes a search control for receiving search strings and responsive thereto providing search completions that represent one or more geographic areas and reach information for each geographic area. The campaign tool also includes a control for adding a geographic area to a campaign, excluding the geographic area from the campaign, or presenting a map of the geographic area.

Abstract: Configurations for targeting nearby geographic locations for managing content are disclosed. The subject technology identifies one or more geographic locations for targeting content from a campaign for delivery to users and the campaign associated with a content sponsor. One or more geographic locations that are nearby the one or more geographic locations associated with the campaign are automatically presented to the content sponsor, including presenting candidate nearby geographic locations and estimated reach information along with each candidate geographic location. The subject technology receives a selection of one or more candidate geographic locations for inclusion in the campaign, and adds the selection to the campaign.
