  • Patent number: 11953468
    Abstract: According to various, but not necessarily all, embodiments there is provided an apparatus comprising means for: controlling one or more electroacoustic transducers of a device to create a standing wave having a displacement antinode at an expected location of a component of the device; receiving a signal representing sound generated by vibration of the component driven by the standing wave; causing analysis of the signal to determine whether there is a defect based on whether the signal represents a sound that would be expected to result from vibration of the component driven by the standing wave in the absence of a defect.

  • Patent number: 11899774
    Abstract: An authentication apparatus and a method to devise an authentication tool is provided for facilitating determination of authenticity or genuineness of an article with reference to a captured image or a purported primary image of an information bearing device on the article. The authenticity or genuineness of an article is determined with reference to whether a captured image is a primary image of an authentic information bearing device using a trained neural network. The neural network is trained using training images comprising imperfect images having varying degrees of image imperfections which are introduced under controlled conditions.

  • Patent number: 11699299
    Abstract: According to various, but not necessarily all, embodiments there is provided an apparatus comprising means for: determining at least two locations at which a user touches a device; selecting a first location and a second location from the at least two locations to define a transmission path for an acoustic signal through the user; applying an acoustic signal to the user through the first location; detecting an acoustic signal transmitted through the user at the second location; and analysing the detected acoustic signal to determine if it is indicative of transmission of the applied acoustic signal through an authorised user based on a known bioacoustic signature of the authorised user.

  • Patent number: 11683107
    Abstract: According to various, but not necessarily all, embodiments there is provided an apparatus comprising means for: obtaining a propagation profile for wireless signals transmitted between at least two devices via a creeping wave along a user's skin; causing transmission of electromagnetic radiation towards a plurality of locations on a target user's body to obtain dielectric properties of their skin at the plurality of locations based on an amount of the electromagnetic radiation reflected from each location; determining whether the propagation profile correlates with a realizable creeping wave along the target user's skin, the realizability being based on the obtained dielectric properties of their skin; and forming an association between the target user and the at least two devices based on a strength of correlation between the propagation profile and a realizable creeping wave.

  • Patent number: 11636501
    Abstract: The embodiments set forth techniques for delivering relevant news articles to users. The techniques can involve auditioning different categories of news articles (e.g., entertainment, sports, technology, etc.) to a user to create a pleasant onboarding experience that requires minimal user input. As time progresses, affinity information for the user is gathered from various sources (e.g., news readers, web browsers, third-party applications, etc.). The affinity information can be used to (1) suggest additional categories in which the user might be interested, and (2) increase the accuracy by which subsequent news articles are delivered to the user. Additionally, feedback information about the user's interaction with the subsequent news articles can then be obtained, and various metrics associated with these news articles can be updated to reflect the user's interaction. In turn, the various updated metrics can enable these news articles to be delivered to other users in a more accurate manner.

  • Publication number: 20230109044
    Abstract: An apparatus and/or method may be implemented in accordance with aspects characterized herein. A controller may identify a state of an image forming apparatus and generate feedback signals to instruct a mechanical actuator, which moves an imaging component of an image forming apparatus to indicate the state. Accordingly, mechanical printing type componentry, such as linear, rotary, print head or scanning mechanisms, may be utilized for carrying out printing-related functions and to generate audible, visual and/or haptic feedback.

  • Patent number: 11496698
    Abstract: According to various, but not necessarily all, embodiments there is provided an apparatus comprising means for: capturing or causing capture of an image of an object using a rolling shutter having an aperture width and shutter scan speed; during the image capture, projecting or causing projection of electromagnetic radiation with a fixed-spatial, time-variable distribution onto the object, wherein the time-variable distribution of the projected electromagnetic radiation, the aperture width of the rolling shutter, and the shutter scan speed of the rolling shutter, are such that adjustment of one or more of these would not decrease a proportion of projected electromagnetic radiation captured which is directly reflected from a surface of the object.

  • Publication number: 20220262156
    Abstract: This disclosure describes techniques for providing instructions when receiving biometric data associated with a user. For instance, an electronic device may detect a portion of a user, such as a hand. The electronic device may then determine locations of the portion of the user relative to the electronic device. Based on the locations, the electronic device may cause a visual indicator to provide instructions to the user for placing the portion of the user at a target location relative to the electronic device. For example, the visual indicator may emit light indicating that the portion of the user is off-centered, angled, too low, and/or too high. After providing the instructions and determining that the portion of the user is at the target location, the electronic device may capture at least an image of the portion of the user and use the image to identify an account.

  • Patent number: 11361177
    Abstract: A composite information bearing device comprising an image pattern and a human readable data device. The human readable data device includes a set of human readable data symbols representing a first set of data. The first set of data includes a first data portion and a second data portion. The image pattern represents a second set of data and comprises a third data portion. One of the first or said second data portions is to form an identification code upon combination or concatenation with said third data portion, and the other one of said first or said second data portions not forming part of said identification code is to form a verification code, the verification code being related to said identification code by a scheme of operation.

  • Patent number: 11281735
    Abstract: In some implementations, a computing system can determine how important an investment identifier is to a content item that mentions the investment identifier. For example, a content item may describe a story, event, etc., related to an investment identifier. The content item may mention the investment identifier by mentioning the investment identifier, proxies for the investment identifier, or other equivalents associated with the investment identifier. The computing system can determine locations in the content item where the investment identifier is mentioned and/or how frequently the investment identifier is mentioned. Based on the locations and/or frequency of mentions, the computing system can determine an importance score that represents how important the investment identifier is to the story described by the content item. The importance score can be stored in metadata for the content item and used when determining which content items to present to a user.
