  • Patent number: 11965810
    Abstract: An exemplary method and system is disclosed that facilitate the integration of multiplexed single-cell impedance cytometry in a high throughput format, which can be deployed upstream from microfluidic sample preparation and/or downstream to microfluidic cell separation. In exemplary method and system may employ impedance-based quantification of cell electrophysiology on the same microfluidic chip (i.e., “on-chip”) to provide distinguishing phenotypic information on the sample, without the need for additional sample handling, preparation or dilution steps as would be needed for other flow cytometry techniques.

  • Patent number: 11922892
    Abstract: The disclosed devices may include a driver circuit including a voltage boost circuit, a pulse modulation controller, and optionally a headroom processor. The voltage boost circuit may be configured to receive a device input voltage (such as a battery voltage) and generate a backlight drive voltage. The pulse modulation controller may be configured to provide a pulse modulation signal to the voltage boost circuit, and may include a digital circuit or an analog circuit. Example devices may include a backlight unit receiving the backlight voltage. The optional headroom processor may provide a headroom signal to the pulse modulation controller based on a headroom voltage determined from the backlight unit. Devices may further include a backlight unit including an arrangement of light-emissive elements, and may include display devices such as head-mounted devices. Various other methods, systems, and computer-readable media are also disclosed.

  • Patent number: 11508484
    Abstract: Systems and methods have been developed to increase user compliance and adherence to respiratory therapy devices. For instance, in some examples the disclosed technology may monitor usage data output from a respiratory therapy device to determine, based on the trends of usage, when a user is likely to terminate or reduce usage within a specified time window. Flagging a user may also trigger further actions to automatically intervene before the user terminates engagement with the service.

  • Patent number: 11297150
    Abstract: Method, system, and programs for measuring user engagement. In one example, a model generated based on user activities with respect to a plurality pieces of content is obtained. One or more actual occurrences of the user activities with respect to one piece of the plurality pieces of content are identified. One or more future occurrences of the user activities with respect to the piece of content are estimated based on the model. A user engagement score with respect to the piece of content is calculated based on the one or more actual occurrences of the user activities and the one or more future occurrences of the user activities.

  • Patent number: 11080287
    Abstract: The present teaching, which includes methods, systems and computer-readable media, relates to ranking content from multiple disparate sources including a person's personal data sources and non-personal data sources. The disclosed techniques may include obtaining a plurality sets of content associated with a request from a person, each of which being from a separate data source, and applying a model for each set of content to obtain a set of features for each piece of content in the set of content, wherein the model is specific to a data source from where the set of content comes from. Each set of features for each piece of content of the set of content may be normalized with respect to a common space to generate a normalized feature set. Further, a score for each piece of content from a set of content may be estimated based on the normalized feature set for the piece of content, and based on the score of the piece of content, each piece of content of the plurality sets of content may be ranked.
