  • Publication number: 20210173704
    Abstract: A computing device can obtain usage data associated with the device. The usage data indicate how the computing device operates or how the device is used. The device can analyze the usage data to recognize usage patterns. The usage patterns can correspond to recurring actions or tasks initiated by the user using the device, such as actions or tasks initiated due to the user's habits and/or routines. Based on the usage patterns, the device can determine a task that has a sufficient likelihood of being performed using the device within a specified or determined time (e.g., 5 minutes from now, one year from now, etc.). The device can provide information (e.g., recommendations) associated with the task, and likely relevant to the user. The user can use the provided information to perform the task, thereby increasing the ease of access or efficiency associated with performing the task.

  • Publication number: 20210034192
    Abstract: A system and method for identifying a user of a device includes comparing audio received by a device with acoustic fingerprint information to identify a user of the device. Image data, video data and other data may also be used in the identification of the user. Once the user is identified, operation of the device may be customized based on the user. Further, once the user is identified, data can be associated with the user, for example, usage data, location data, gender data, age data, dominant hand data of the user, and other data. This data can then be used to further customize the operation of the device to the specific user.

    Abstract: A phosphor in glass (PiG) cover is provided to modulate the color emitted from an LED chip. The PiG cover includes an active layer including glass and phosphor, and a secondary layer including glass and free of phosphor. The active layer is stacked on the secondary layer to form the PiG cover. Alternately the PiG includes an active layer sandwiched between two secondary layers. Two or more active layers can be stacked to each other or disposed side-by-side. An LED chip is arranged under the PiG cover to form an LED package.

  • Patent number: 10577279
    Abstract: A method of modifying glass frit involves treating the frit with a grain-boundary-healing compound. The method increases transmission and clarity, and reduces haze of a fired enamel coating made from such modified glass frit as compared to a coating not made from such modified glass frit. The grain-boundary-healing compound influences the chemistry at the grain boundaries to prevent haze. The compound burns out to yield a fluxing material that dissolves alkaline carbonates or bicarbonates on the surface of the glass frit. The dissolved species are incorporated into the enamel coating, thereby promoting the fusion of the glass frit and reducing the amount of haze in the enamel coating. The additives also function to prevent the formation of seed crystals on the surface of the glass frit that may inhibit the fusion of the glass frit.

  • Publication number: 20180186687
    Abstract: A sintered machinable glass-ceramic is provided. The machinable glass-ceramic is formed by mixing phyllosilicate material having a sheet structure, with a glass fit and firing the mixture at relatively low temperatures to sinter the phyllosilicate, while maintaining the sheet-like morphology of the phyllosilicate and its associated cleaving properties. The sintered machinable glass-ceramic can be machined with conventional metal working tools and includes the electrical properties of the phyllosilicate. Producing the sintered machinable glass-ceramic does not require the relatively high-temperature bulk nucleation and crystallization needed to form sheet phyllosilicate phases in situ.

  • Patent number: 9972037
    Abstract: Systems and methods for providing wireless charging via radio-frequency (RF) carrier wave. The system can enable user equipment (UE) to charge wirelessly using RF waves when the UE is not it use. The system can activate wireless charging based in part on the battery level of the UE. The system can also initiate wireless charging when the UE is sufficiently idle (e.g., not being used for a call or web browsing). The system can also ensure that the signal strength of the carrier waves at the UE is sufficiently strong to support wireless charging. One or more system components can ensure that the threshold charge level, threshold signal strength, and threshold utilization rate are met and that the UE is authorized for wireless charging on the network. Wireless charging may be billed to the user according to usage (e.g., kWh), at a flat rate, or per instance.
