  • Patent number: 10699320
    Abstract: In one embodiment, a method includes, receiving a request, from a client system of a first user, to access a marketplace including products offered for sale by a second user. The method includes, by the computing device, filtering a set of product listings based on multiple respective product-listing embeddings and a content-interaction embedding associated with the first user. Each product listing includes a description of one of the products in the marketplace. The method includes ranking each product listing in the filtered set based at least on a product-score representing a likelihood of the first user interacting with the respective product. The product-score is based on interaction information associated with the first user, product information associated with the product, and sparse information associated with the first user. The method includes sending, to the client system of the first user, a subset of the ranked product listings.

  • Patent number: 10430762
    Abstract: In an example embodiment, a cohort to target is identified, the cohort including a plurality of members of a social networking service having member profiles that all share at least one attribute value. A minimum number of eligible members of the cohort in order to provide relevant statistical insights from confidential data submitted by eligible members of the cohort is identified, and based on an assumed response rate for eligible members of the cohort, a total number of eligible members in the cohort, and the minimum number of eligible members of the cohort in order to provide relevant statistical insights, the eligible members are divided into a first wave and a second wave.

  • Patent number: 10430816
    Abstract: In an embodiment, a cohort to target is identified, the cohort including a plurality of members of a social networking service having member profiles that all share at least one attribute value. A minimum number of eligible members needed to provide relevant statistical insights from confidential data submitted by eligible members of the cohort is identified. Then, based on an assumed response rate for eligible members of the cohort, a total number of eligible members in the cohort, and the minimum number of eligible members needed to provide relevant statistical insights, it is determined that an estimated amount of responses to invitations to submit confidential data to eligible members of the cohort is less than the minimum number of eligible members needed to provide relevant statistical insights. In response to the determination, the cohort is altered to include eligible members from at least one other cohort, and the process repeated.

  • Patent number: 9831208
    Abstract: A driving chip and a display device, relating to the technical field of driving chip for displays, are disclosed. A surface of the driving chip has a first edge and a second edge opposite to each other. The driving chip includes connecting bumps and supporting bumps, which are arranged along the first edge to form at least one first bump column, and at either end of the first bump column, there is at least one of the supporting bumps; the connecting bumps and the supporting bumps are arranged along the second edge to form at least one second bump column, and at either end of the second bump column, there is at least one of the supporting bumps. A surface of the driving chip according to embodiments of the invention has bump columns, a supporting bump is disposed at an end of a bump column, and acts to support the driving chip favorably. Thus, upon bonding and packaging, the driving chip can bear a force in equilibrium as a whole, and occurrence of a problem of impression defectiveness is avoided.

  • Publication number: 20160275554
    Abstract: An online system tracks stores information identifying content provided by third party systems and accessed by online system users as well as interactions with advertisements performed by online system users. When the online system identifies an opportunity to present an advertisement to a viewing user, the online system identifies content from third party systems accessed by the viewing user and content from third party systems accessed by additional online system users who interacted with advertisements. A score is computed for various advertisements based at least in part on correlations between content from third party systems accessed by the viewing user and content from third party systems accessed by additional online system users who interacted with advertisements. The online system selects candidate advertisements to evaluate for presentation to the viewing user based on the scores.

  • Patent number: 6560804
    Abstract: The present invention relates to a system and a method for detecting and monitoring the distance between a patient and a reference point on an inflatable air mattress and for controlling the air supply to that mattress in relation to such distance. The patient distance sensing system includes a rigid support frame such as a bed frame, an inflatable air mattress positioned atop the bed frame with the upper surface of the inflatable air mattress forming a patient support surface, an air supply operable to provide controlled variations in air supply, and a series of patient distance sensing devices. Such devices including a heterodyning proximation detector, a force responsive distance sensing device, and a light responsive sensing device. Each device is operable to act separately or cooperatively in maintaining a therapeutically beneficial patient support surface through variable control of the delivery of inflation pressure to the air mattress.

  • Patent number: 6447460
    Abstract: An automated screening tool for the exclusion of deep venous thrombosis generally comprises a sensor array for gathering thermal data from the lower limbs of a patient suspected of DVT; a processor for automated analysis of the gathered data; and a display device for reporting the exclusion or non-exclusion of DVT. In the preferred embodiment of the present invention, a microprocessor based system is utilized to control the gathering of thermal data and, thereafter, the reporting of the gathered data to the processor. According to the preferred method for use of the present invention, the gathered thermal data is utilized, alone or in combination with other indicators, as a factor for exclusion of DVT based upon an implemented algorithm. According to the preferred embodiment of the present invention, a neural network or genetic algorithm is implemented within the processor in order to make an entirely objective determination relative the presence of DVT.
