  • Patent number: 11766235
    Abstract: The present disclosure describes ultrasound imaging systems and methods configured to identify ovarian follicles by applying a neural network to pre-processed ultrasound image frames. Systems may include an ultrasound transducer configured to acquire echo signals responsive to ultrasound pulses transmitted toward a target region. One or more processors communicatively coupled with the ultrasound transducer may be configured to generate at least one image from the ultrasound echoes. A threshold may be applied to the image frame that differentiates pixels representative of an ovarian follicle present in the target region from other subject matter. The processors may apply a neural network to the thresholded image frame, in which the neural network determines the presence of the ovarian follicle in the thresholded image frame. The processors also may generate an indicator based on the presence of the ovarian follicle and display the indicator on a user interface.

  • Patent number: 11666306
    Abstract: The present invention relates to a device (10) for detecting a misuse of a medical imaging system (20), comprising a data interface (12) for acquiring medical image data (24) and audit log data (26) from the medical imaging system (20); a processing unit (14) which is configured to configured to analyse the medical image data (24) to determine whether or not a part of a fetus is imaged in the medical image data (24), to compare the medical image data (24) and the audit log data (26) with each other, and to determine based on said comparison whether there is a mismatch between the medical image data (24) and the audit log data (26); and a feedback unit (16) which is configured to generate a misuse alert signal if a mismatch is detected by the processing unit (14).

  • Publication number: 20200229798
    Abstract: An ultrasound system and method enable ultrasonic imaging by inexperienced personnel at the home of a patient under the guidance of a remotely located diagnostic imaging expert. Improper use of the scanning device is prevented by allowing the remotely located imaging expert to enable or disable the transmission of ultrasound energy by the ultrasound system. Other functions of the ultrasound system may also be controlled by the remotely located expert, such as determining whether acquired ultrasound images can be viewed locally on the ultrasound system.

  • Patent number: 10552892
    Abstract: Systems and methods are disclosed that use social networking profiles of users to generate personalized content of display pages. The personalized content may be generated using profile data retrieved via an application program interface of a social networking system, and may be presented on the display pages of a distinct system, such as a site that hosts an electronic catalog of items. The personalized content may include features that allow a user to indicate a like or preference for an item and that can be customized based on, e.g., the extent of the user's social network or the influence the user has over other potential users of the catalog system. Systems and methods are also disclosed that use the social networking profiles to generate personalized messages that can be posted to social network contacts of the user to provide information about items for which the contacts may be interested.

  • Patent number: 10447778
    Abstract: Implementations generally relate to synchronizing peer nodes in networks. In one embodiment, a method includes generating a data sequence number. The method also includes associating the data sequence number with a data item. The method also includes sending the data item and the data sequence number to each peer node of a plurality of peer nodes. The method also includes determining if an acknowledgment has been received from each peer node, wherein each acknowledgment indicates the peer node that sent the acknowledgment and indicates the data sequence number. The method also includes resending the data item and the data sequence number to one or more peer nodes based on a predetermined policy.

  • Publication number: 20190269386
    Abstract: An ultrasound system and method enable ultrasonic imaging by inexperienced personnel under the guidance of a remotely located diagnostic imaging expert. Improper use of the scanning device is prevented by controlling the device to present only low quality images to the person conducting the scan, while images of high quality are sent to the remote expert for diagnosis. Thus, an effective diagnosis by the expert is facilitated while providing at the scanning site only images which, while sufficient to provide visual guidance of the scanning procedure, cannot be used improperly by persons at the site of the patient being scanned.

  • Patent number: 9705826
    Abstract: Methods, systems and computer readable media for L2 redirection in multi-chassis link access group (LAG) environments are described. In some implementations, the method can include determining, at a core switch, a failure of a link in a split multi-link trunk (SMLT), and building, at the core switch, a table mapping each destination media access control (MAC) address to an incoming split multi-link trunk port. The method can also include sending, from the core switch, a link layer discovery protocol (LLDP) redirect message on a per-destination MAC address and per-source access switch basis. The method can further include maintaining a same mapping for each MAC address not hashed to a cluster peer with the failed link or being mapped to a non-inter switch trunk (IST) port.
