  • Patent number: 10408988
    Abstract: Techniques for creating, configuring, and employing diffusion light devices are presented. Such light device(s) can comprise or be associated with a light management component (LMC) that can employ sensors to monitor environmental conditions in a defined area of people or vehicles, and a diffusion component that can diffuse or otherwise process light. At a least a portion of the diffusion component and/or a light component can be formed of a fabric that can emit light and/or diffuse light. LMC can enhance function of the light device to manage diffusion of light or perform other tasks to enhance user experience and safety and security of people or vehicles. Based on results of analyzing sensor data relating to the conditions, LMC can determine and facilitate implementing an adjustment(s) to a parameter(s) of the diffusion component or light component to achieve desired emission or diffusion of light.

  • Publication number: 20190191528
    Abstract: Techniques for employing an enhanced light device to determine desirable information to a user are presented. Such light device(s) can comprise or be associated with a light management component (LMC) that can employ sensors to monitor respective characteristics or conditions of a device, an environment, and/or a user to determine respective contexts for the device, environment, or user, wherein the user can interact with or be in proximity to the device or environment. The light device(s) collects data, including sensor data, relating to the device or environment from the device, the environment, or other data sources. The LMC determines a desirable subset of information to present to the user based on the respective contexts. The LMC facilitates presenting the desirable subset of information to the user via the light device or a communication device of the user that is communicatively connected to the light device.
