  • Patent number: 9940583
    Abstract: This disclosure is directed at least partly to a cloud prediction device that provides information to a kiosk. The cloud prediction device may receive information from a user device associated with a user, such as travel information, itineraries, calendar events, emails, etc, which may be used to determine the information. The information may also include user preferences, user recommendations, and/or historical data that may be used to determine content to be provided by the kiosk for the user and/or other users. The kiosk may provide innovative user interfaces to engage a user and provide high speed data transfer of content to a user device associated with the user. The kiosk may be located in frequently visited locations such as travel terminals or public spaces.

  • Patent number: 9665249
    Abstract: A computing device can be controlled based on changes in the angle of a user's head with respect to the device, such as due to the user tilting the device and/or the user tilting his head with respect to the device. Such control based on the angle of the user's head can be achieved even when the user is operating the device “off-axis” or when the device is not orthogonal and/or not centered with respect to the user. This can be accomplished by using an elastic reference point that dynamically adjusts to a detected angle of the user's head with respect to the device. Such an approach can account for differences between when the user is changing his natural resting position and/or the resting position of the device and when the user is intending to perform a gesture based on the angle of the user's head relative to the device.

  • Patent number: 9577521
    Abstract: A circuit for controlling a switch in a power converter in which peak current is regulated to achieve a specified average current through a load. Control logic is operable to monitor a voltage across a sensing resistor such that when the voltage across the sensing resistor reaches or exceeds a threshold value, the control logic generates a signal that causes a switch to be turned OFF.

  • Publication number: 20160092034
    Abstract: This disclosure is directed at least partly to a kiosk that provides innovative user interfaces to engage a user and provide high speed data transfer of content to a user device associated with the user. The kiosk may be located in frequently visited locations such as airports. The kiosks may advertise content and provide instructions to users about how to receive some of the content on user devices via a high speed data transfer. The high speed data transfer may use high speed data transfer protocols that enable download of a standard definition full length movie (e.g., less than 1 GB of data) in less than a couple of seconds or download of a high definition full length movie (e.g., 2-3 GB of data) in a few seconds. Besides, movies, other content may be downloaded such as electronic documents, music, games, and other electronic media available from an electronic catalog.

  • Publication number: 20160026261
    Abstract: An electronic device can be configured to enable a user to provide input via a tap of the device without the use of touch sensors (e.g., resistive, capacitive, ultrasonic or other acoustic, infrared or other optical, or piezoelectric touch technologies) and/or mechanical switches. Such a device can include other sensors, including inertial sensors (e.g., accelerometers, gyroscopes, or a combination thereof), microphones, proximity sensors, ambient light sensors, and/or cameras, among others, that can be used to capture respective sensor data. Feature values with respect to the respective sensor data can be extracted, and the feature values can be analyzed using machine learning to determine when the user has tapped on the electronic device. Detection of a single tap or multiple taps performed on the electronic device can be utilized to control the device.

  • Patent number: 9148925
    Abstract: A circuit for controlling a switch in a power converter in which peak current is regulated to achieve a specified average current through a load. The circuit can include a first input to receive a voltage corresponding to a pre-specified target average current through the load, and a second input to receive a voltage corresponding to a voltage across a sensing resistor immediately after the switch turns ON. The circuit generates a threshold value that is approximately equal to twice the voltage corresponding to the pre-specified target average current through the load, minus the voltage corresponding to a non-zero voltage across the sensing resistor just after the switch turns ON. Control logic is operable to monitor a voltage across the sensing resistor such that when the voltage across the sensing resistor reaches or exceeds the threshold value, the control logic generates a signal that causes the switch to be turned OFF.

  • Publication number: 20140308416
    Abstract: A wine aerator includes a container having walls bounding an interior compartment. The compartment has an open condition in which a volume of a type of wine to be aerated is admitted to partially fill the compartment, and a closed condition for hermetically sealing the wine in the compartment. The remainder of the compartment contains a volume of air. A plurality of indicators are provided on the container for visually indicating different air/wine volume ratios based on the type of wine in the compartment. An agitator agitates the hermetically sealed wine with a selected one of the ratios for a predetermined time to aerate the wine.

  • Patent number: 8573438
    Abstract: This application relates to the field of removable handles for cookware. The use of a single interchangeable and removable handle with different pieces of cookware has several advantages. One advantage is that the overall assembly is much smaller to store, as the handle may be removed and stored in a separate location, reducing the overall size of the assembly. In addition, a single handle may be utilized for multiple cooking vessels as it is common for only one handle to be utilized at a single time. Even though multiple cooking vessels may be used simultaneously, the handle is only utilized for repositioning or stabilizing the cooking vessel. In this way, when no cooking vessel is in use, only one handle need be stored, rather than separate (possibly attached) handles for each article of cookware.
