  • Publication number: 20240147243
    Abstract: An embodiment includes a method to increase the efficiency of security checkpoint operations. A security checkpoint kiosk serves as a Relying Party System (RPS). The RPS establishes a secure local connection between the RPS and a User Mobile-Identification-Credential Device (UMD). The RPS sends a user information request to the UMD, via the secure local connection, seeking release of user information associated with a Mobile Identification Credential (MIC). The RPS obtains authentication of the user information received in response to the user information request. The RPS retrieves user travel information based on the user information. The RPS determines that the user travel information matches the user information. When the user travel information matches the user information, the RPS approves the user to proceed past the security checkpoint kiosk.

  • Patent number: 10206534
    Abstract: A system, device and method for the brewing of a capsule. The device comprises a first chamber portion and a second chamber portion movable with respect to each other to be moved between an open position and a closed position. The device further comprises a capsule handler arranged to enable insertion therein of the capsule and to position said capsule in a brewing position, wherein the capsule handler retains the capsule in the brewing position when the capsule handler is in a ready position. When the first chamber portion and the second chamber portion are moved with respect to each other from the closed position to the open position, the capsule can fall freely from the brewing position under the influence of gravity when the capsule handler is in an ejection position.

  • Patent number: 10162981
    Abstract: Some embodiments enable a user of an electronic device to selectively secure applications and/or content of the electronic device. For instance, certain embodiments enable a user to password protect applications (e.g., email, calendar, contacts, photos) within a single environment. In some embodiments, a user can selectively secure specific content (e.g., work-related email messages, personal emails, work-related calendar entries, corporate contacts) within an application. Further, some embodiments enable a user to specify which applications and/or types of content the user would like to password protect. For instance, a user that has sensitive work-related information stored on or accessible through the user's device may choose to password protect work-related applications (e.g., work email account) and content (e.g., work documents, work-related calendar entries).

  • Patent number: 9645642
    Abstract: A low distraction interface can be provided for an electronic device by monitoring information such as a gaze direction of a user. A device can be configured to only display information to a user when the user is looking substantially toward the device, and can be configured to present that information in a way that is of minimal distraction to others nearby. The user can control aspects of the display by looking away from the device, continuing to look at the device for a period of time, or otherwise providing input without physically interacting with the device. Such an approach can be beneficial for settings such as business meetings where a user might want to obtain information from the device but does not want to appear inconsiderate by picking up and checking information on the device.

  • Patent number: 9514221
    Abstract: Systems, methods, and computer-readable storage media are provided for utilizing part-of-speech (POS) tagging of both the words included in a search query and the words included in potential search result documents to improve query alteration accuracy and search result ranking. Upon receiving a search query, POS tags are assigned to the words comprising the query to create query word-tag pairs. The query word-tag pairs are utilized to reformulate the query and are compared with document word-tag pairs included in a plurality of potential search result documents to determine a degree of similarity. The degree of similarity is utilized as an input in scoring and/or ranking the relevance of the potential search result documents with respect to one another.

  • Patent number: 9478195
    Abstract: Some embodiments enable a first electronic device (e.g., a notebook computer) to obtain state information directly from another electronic device (e.g., a smartphone) so that the first electronic device may replicate a state of content of the other computing device. This is useful when a user of an electronic device desires to switch between one device and another device such that the user may continue an activity (e.g., playing a video game) on another device without having to restart the activity. This is also useful when a user of a first electronic device attempts to replicate the state of the activity on a second device from another user such that both users may participate in the same activity. In some embodiments, a user of a device may obtain content from a server and state information from another device to replicate the state of content on the other device.
