  • Publication number: 20200179196
    Abstract: A seat assist device is described. The seat assist device includes a base, a lift platform having a front portion and a rear portion, with the front portion of the lift platform being pivotally connected with the base. A lifting arm is connected with the rear portion of the lift platform. The lifting arm extends from the lift platform to project beyond the front portion of the lift platform, with the lifting arm terminating in handles for grasping by a user. A lift bar is pivotally connected between the base and the lifting arm, whereby a user sitting upon the seat assist device can press downward on the handles to cause the rear portion of the lift platform to rise and, in doing so, assist the user in rising from a seated position.

  • Patent number: 10671947
    Abstract: One embodiment of the invention disclosed herein provides techniques for distributing tasks to skilled workers participating in a managed crowd-sourcing workforce. A crowd worker routing system receives a request for a task assignment from a first worker participating in the crowd-sourcing workforce. The crowd worker routing system retrieves one or more scores associated with the first worker, wherein each score is related to the performance of the first worker with respect to completing a prior set of task assignments. The crowd worker routing system determines that a first task assignment included in a first set of task assignments is related to a first score included in the one or more scores. The crowd worker routing system determines whether to route the first task assignment to the first worker for completion based on the first score and one or more routing rules.

  • Publication number: 20200162797
    Abstract: Methods and apparatus for providing delivery of content to client devices of a network via both multicast and unicast mechanisms. In one embodiment, a system for use in a managed content delivery network is described to bridge multicast to unicast, so that the total network bandwidth consumption is significantly lower than a corresponding unicast-only delivery solution, yet which still provides improved quality of service and user viewing experience as compared to a multicast-only delivery solution. In addition, various exemplary aspects of the present disclosure are readily adapted for real-time multicast to unicast streaming of audio and data to, among other things, minimize network bandwidth usage, while maintaining the guaranteed delivery of unicast streams with little or no modification to the existing client device logic.

  • Patent number: 10633897
    Abstract: A tamper-proof lock includes: a housing, shaft/handle, cam, lever, spring, and plate. The shaft is pivotally mounted in a housing orifice, with the cam pivotally mounted to the shaft. The cam has first and second shaped openings at first and second respective radial positions, and an arcuate recess. The lever is secured to the shaft, and has a protrusion that alternately engages each of first and second ends of the arcuate recess to respectively/selectively drive the cam to rotate/counter-rotate in first and second directions, into locked and unlocked cam positions. The spring biases the plate for a protrusion thereon to be respectively received within each of first and second shaped cam openings, when aligned therewith at those cam positions, and for a curved surface of the plate to be correspondingly received within first and second curved cam recesses, respectively, when aligned therewith, which facilitate withdrawal of the plate protrusion.

  • Publication number: 20200092598
    Abstract: Methods, systems and devices are provided for communicating multimedia content over a service provider network. A network server may receive an audio-video stream from a content provider server, relaying the audio-video stream to a receiver device via the service provider network, receive an operating mode notification identifying a user behavior from the receiver device, and ceasing the relaying of the audio-video stream to the receiver device based on the user behavior. The network server may also alter the audio-video stream based on the received operating mode notification and send the altered audio-video stream to the receiver device via the service provider network.

  • Publication number: 20200073516
    Abstract: A user interface, system and method for optimizing a patient problem list in an electronic medical record or electronic health record in which entries in the problem list are removable or otherwise editable if they were entered into the problem list longer ago than a limited duration window to which the entries are categorized. In order to determine that categorization, the problem list entries are mapped to concepts or lexicals of an interface terminology, which in turn is mapped to concepts of another terminology, and those concepts are analyzed with respect to one or more criteria used to establish the limited duration window.

  • Patent number: 10570652
    Abstract: A sash fastener for securing a slidable and tiltable sash window includes a lock assembly and left-hand and right-hand latch assemblies. The lock assembly is mounted upon the sash window meeting rail, and includes a pivotable cam to engage a keeper on the master frame, a handle to pivot the cam, and a pair of pivotable arms, each extending into the meeting rail. A link selectively connects the two arms, and when actuation of the handle causes the cam to rotate, it may selectively drive one of the arms to pivot, with the link causing the other arm to pivot. The left- and right-hand latch assemblies each include a housing, biasing means, a latch member with an adjustable receiver clip having an opening therein configured to receive one of the arms of the lock assembly, within the meeting rail, with movement of the arms actuating the latch to permit tilting.

  • Publication number: 20190340537
    Abstract: A personalized score for a place that a user may want to visit is computed and displayed to the user. The score is computed based on at least one of inferred or explicit parameters, using machine learning. The score may be displayed to the user in connection with the place, and in some examples explanations of the underlying factors that resulted in the score are also displayed. Because each user is unique, the score may be different for one person than for another. Accordingly, when a group of friends are deciding on a place to visit, such as a place to eat, the personalized score for a given restaurant may be higher for a first user than for a second user.

  • Patent number: 10339663
    Abstract: Systems and methods are disclosed for generating georeference information with respect to aerial images. In particular, in one or more embodiments, systems and methods generate georeference information relating to aerial images captured without ground control points based on existing aerial images. For example, systems and methods can access a new set of aerial images without ground control points and utilize existing aerial images containing ground control points to generate a georeferenced representation corresponding to the features of the new set of aerial images. Similarly, systems and methods can access a new image without ground control points and utilize an existing georeferenced orthomap to produce a georeferenced orthomap corresponding to the features of the new image. One or more embodiments of the disclosed systems and methods permit users to obtain georeference information related to new images without the need to place ground control points or collect additional georeference information.
