  • Patent number: 10484383
    Abstract: A content management system can tag a client installer with an information tag linking the client installer to a user account. The client installer can be configured to install the client-side application on the client device and pass the identification tag to the installed client-side application. The client-side application can transmit the identification tag to the content management system, which can use the identification tag to identify the linked user account and log the client-side application into the user account. The content management system can implement several verification measures such as limiting the number of times and when an identification tag can be used, as well as IP addresses that can use the identification tag. The content management system can also use data cached by the web-browser application to determine if the web-browser application was used to access the user account in the past.

  • Publication number: 20190325009
    Abstract: A multi-user collaboration system. User-specific change markings are applied to a collaboration object. The user-specific changes to be presented are time-oriented, based on a time of a last view of the collaboration object. A plurality of users that have access to the collaboration object are identified. Time-ordered versions of the collaboration object are captured. Each captured version corresponds to changes made to the collaboration object by any of the users. When a request to view the collaboration object is received from a subject user, a method determines the latest version of the collaboration object and also determines the specific last accessed version of the collaboration object that was seen by the subject user. The two versions are compared, and the comparison changes are used to generate user-specific change markings. The collaboration object with the generated user-specific change markings is presented by rendering the user-specific change markings on respective user-specific devices.

  • Patent number: 10453656
    Abstract: Embodiments of the present invention provide a plasma chamber design that allows extremely symmetrical electrical, thermal, and gas flow conductance through the chamber. By providing such symmetry, plasma formed within the chamber naturally has improved uniformity across the surface of a substrate disposed in a processing region of the chamber. Further, other chamber additions, such as providing the ability to manipulate the gap between upper and lower electrodes as well as between a gas inlet and a substrate being processed, allows better control of plasma processing and uniformity as compared to conventional systems.

  • Patent number: 10444144
    Abstract: We disclose a method of tagging nutritional or drug compositions using chemical entities which are known to be safely consumed and which are detectable using known techniques, including near IR spectroscopy. The chemical entities used as tags may be detected in easily obtainable biological samples, including urine and feces. The biological sample may be deposited into a medical toilet which may analyze the biological sample using an analytical device associated with the medical toilet. The tag may be identified and quantified to then identify and quantify the nutritional or drug composition the subject consumed along with the tag. This system may be used to track the source of a food or drug, confirm compliance to a prescribed diet or drug treatment, confirm drug consumption in clinical trials, identify the source of contaminated food, and identify the food substances used to produce food products.

  • Patent number: 10408849
    Abstract: We disclose a method of using taggants to assess how and to what extent a drug in a drug composition that a user has consumed has decayed in response to storage conditions and time. The taggants may decay in response to environmental conditions which cause different drugs to lose their efficacy. These environmental conditions may include light, temperature, oxidation, and age. The taggants may be detected in biological samples, including urine and feces. By identifying the taggants, the drug composition and other information relating to the drug may be identified. Additionally, quantification of the different taggants may be used to determine whether the drug in the drug composition has been exposed to environmental conditions which may reduce its efficacy.

  • Patent number: 10407888
    Abstract: The bidet system may include multiple seat scales which may float between the toilet bowl rim and the toilet seat. These seat scales may collect measurements which are transmitted to a controller. The controller may include instructions to calculate a user's center of mass based on the measurements and to identify the position of the user's anus based on the center of mass. The controller may then transmit instructions to a bidet wand directing direct the bidet wand to a position which aims a cleansing fluid spray toward the user's anus. A camera which collects images of the user's anal and urogenital region may also be included in the bidet system. The camera may transmit obfuscated images to the controller to identify other areas of the user's anatomy in need of cleansing. The controller may direct the bidet wand to aim a cleansing fluid spray toward these areas.
