Abstract: The glass composites include glass frit, that when sintered produce a phosphor-containing layer, suitable for use in optical applications. The glass composites can include a crystallizing glass frit, such that phosphor crystals precipitate from the frit composite during sintering, or can include a non-crystallizing glass composition, such that phosphor is added to the frit composite before sintering. The sintering temperatures of the glass are relatively low so that fluorescence of the phosphors will not substantially degrade during sintering. The resulting phosphor-containing layer can be used in various optical applications including those for converting blue light into various color temperatures of white light.

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.

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.

The sensor data may include data collected by sensors on the user's computing device or other computing devices, or data collected by stationary, external sensors. Different types of sensor data may be processed to estimate at least one physical characteristic of the user, such as the user's height, weight, apparel size, age, and so forth. The estimated characteristics may be employed to perform actions based on the user's identity or category, to customize content delivery for the user, or for other purposes.

The computing device may periodically re-compute the probability and change the security level whenever the probability crosses certain predefined thresholds.
