Abstract: An artificial intelligence enabled system is disclosed. The system includes a core component for enabling AI-powered interactions between the system and its users and one or more agents that understand user intent and automatically interact with products and services on the web and/or in the physical world through imitation of a human user.

Abstract: A method of training a system to interact with an application is disclosed. The system includes an interface model configured to translate one or more requests into a sequence of user interface (UI) actions on the application; the interface model comprising: a static model configured to understand UI components of an application; and a dynamic model configured to understand interactions among the UI components and operations that occur when a UI action is completed. The method includes: recording a demonstration of interacting with the application; converting, by the static model, the demonstration into an intermediate representation (IR); and examining the IR, by the dynamic model, to determine an entity, transition, and semantic of an UI that is part of the demonstration.

Abstract: In one embodiment, a method includes sending, to client computing devices that are each associated with a particular user identifier, conversation-group information that identifies a conversation group. The conversation-group information includes a user identifier of a first user of the conversation group. The user identifier of the first user is associated with a first one of the client computing devices. The conversation-group information also includes a server identifier of a streaming server for the conversation group. The method includes receiving, from the first one of the client computing devices, a first audio stream and a first video stream. The method includes receiving, from each of one or more of the client computing devices other than the first one of the client computing devices, a request to access the conversation group.

Abstract: A method for chat room facilitation, the chat room including a plurality of chat groups each including one or more participants, the method including determining a chat group priority for each of a plurality of chat groups, simultaneously presenting audio and video streams of the plurality of chat groups on a user device based on the respective chat group priority, and adjusting a chat group priority in response to a user action.

Abstract: A self-contained, rechargeable LED flashlight uses a zener diode in reverse-breakdown avalanche mode as a low-cost voltage regulator. A second embodiment of the LED flashlight incorporates boost-buck circuitry to allow the internal rechargeable flashlight battery to be recharged through external dry cells. An LED or LED array of the flashlight may be by passed with operator control to allow an internal battery to operate an external device, such as a cellular telephone or the like.

Abstract: A low cost fiber optic lighting display system includes a light source, an electronic shutter having independently controllable pixel elements positioned proximate to the light source, a controller for controlling the pixels, and a plurality of optical fibers, each fiber having input and output ends with the input end of each fiber positioned proximate to the output side of a pixel element or group of pixel elements. The corresponding method includes providing a fiber optic lighting display having a light source, an electronic shutter having independently controllable pixels, a controller connected to the electronic shutter for controlling the pixels, and a plurality of optical fibers, each optical fiber having an input end positioned proximate to a pixel or group of pixel elements and an output end.

Abstract: A micro-controller and a converter circuit provide constant current to light emitting diode array from a power supply with greater voltage than the forward bias voltage of the light emitting diode. A micro-controller operatively coupled with a semiconductor switch and the converter circuit measures the ability of a DC power supply to charge the inductor. Duty cycles of the semiconductor switch are modified according to the measurement of the voltage across the internal resistor of the semiconductor switch so as to supply substantially constant current to the LED array through an inductor regardless of actual battery voltage.
