  • Publication number: 20240137658
    Abstract: A non-transitory computer-readable storage medium stores executable instructions that, when executed by a processor, cause performance of operations comprising operations to access an image captured by an image sensor, obtain a transfer function for mapping pixel values, determine a faces indication that reflects a proportion of a scene depicted in the image that includes one or more human faces, and modify the transfer function based on the faces indication. Modifying the transfer function based on the faces indication comprises adjusting a gain of the transfer function to move the gain closer to unity. The operations include to apply the transfer function to pixel values of the image to produce a tone mapped image and output the tone mapped image.

  • Patent number: 11342054
    Abstract: A system and method to establish a no-login authenticated and contextualized two-ways data flow between a medicine user and the pharmaceutical manufacturer. Near Field Communication (NFC) technology, enabling short-range communication between two compatible devices is utilized via a writeable NFC tag carried by a medication package. The writeable NFC tag includes medication information, anti-counterfeiting information, as well as data about the patient and the prescription. The NFC tag may be read by a user device associated with the patient, enabling the user device to merge this data with the patient's feedback, send this rich flow in a secure way to the manufacturer, who in turn is now able to provide rich contextual guidance to the patient.

  • Patent number: 10489439
    Abstract: A method for extracting entities from a text document includes, for at least a section of a text document, providing a first set of entities extracted from the at least a section, clustering at least a subset of the extracted entities in the first set into clusters, based on locations of the entities in the document. Complete ones of the clusters of entities are identified. Patterns for extracting new entities are learned based on the complete clusters. New entities are extracted from incomplete clusters based on the learned patterns.

  • Patent number: 10378574
    Abstract: It has become apparent that the dimensions of inbuilt-collar driving means of the same nominal size may vary according to the method of manufacture. The dimensions of the collar must therefore be adapted to suit the mode of manufacture, at the expense of its strength or mass. Moreover, the transmissible torque for tightening and loosening operations varies according to a useful wrenching height. In order to have a useful height identical to the height of the shank (7), the idea underlying the invention involves pushing the frustoconical collar (152) of a driving means (151) in towards its center along the extension of the sides of the shank. The inbuilt-collar driving means proposed by the invention is suited to all modes of manufacture, and can be manufactured without adversely affecting the dimensions of the driving means or its installation.

  • Patent number: 9589143
    Abstract: A system and method provide for shared access to a database in a semi-trusted platform. In the method, for each of a set of users, provision is made for regenerating a respective user key, based on a respective predefined user input, such as a hashed password. One or more of the users is authorized to have access to an encrypted database. For each of these, the method includes encrypting a key for the encrypted database with the respective user's user key to generate an encrypted database key. During a user session, one of the authorized users is provided with access to the encrypted database by decrypting the database key from the encrypted database key with the respective user's user key, and decrypting the database, from the encrypted database, with the database key. The database key and each user's user key are not stored on the platform and are thus inaccessible to platform administrators and unauthorized users between user sessions.

  • Patent number: 9501769
    Abstract: A system and method incorporating a multi-function printer (MFP), a mobile device and a server to effect payment of MFP services. The MFP generates and displays a session prepayment code containing identification information for the MFP and for a specific session initiated by a user. The code is entered into the mobile device and the mobile device transmits it to the server. In response, the server transmits a menu of MFP functions and costs to the mobile device, allowing the user to estimate and prepay the cost of the specific session through a service accessible on the mobile device. Once proof of prepayment is received, the server transmits an authorization code to the mobile device and the user inputs it into the MFP. The MFP verifies the authorization code with the server and performs user-selected functions until a time allotted for the specific session ends or until available credit is used, whichever comes first.
