  • Patent number: 10289269
    Abstract: An electronic device for displaying an operation panel is provided in accordance with an aspect of the present disclosure. The operation panel displayed on a screen of the electronic device includes multiple levels of menus. The electronic device displays a first menu of the operation panel on the screen. When a second item being a subordinate item of a first item is selected, the electronic device hides the first menu showing the first item, and displays a second menu of the operation panel on the screen. The second menu includes a central section for identifying the second item.

  • Patent number: 10128035
    Abstract: A coupled inductor array includes a monolithic magnetic core formed of magnetic materials having a distributed gap, first and second windings, and a low-permeability magnetic structure. The first and second windings form respective first and second winding turns around a common winding axis extending in the height direction. The low-permeability magnetic structure is embedded in the monolithic magnetic core and forms a loop around the common winding axis. The low-permeability magnetic structure separates the first and second winding turns in the height direction, and the low-permeability magnetic structure is formed of a magnetic material having a lower magnetic permeability than the one or more magnetic materials forming the monolithic magnetic core. One possible application of the coupled inductor array is in a multi-phase switching power converter.

  • Publication number: 20160110046
    Abstract: Embodiments of the present invention disclose an adjustable timeline user interface for a mobile device. According to one embodiment, in response to a detected touch input on the display of the device, a zoom classification level and/or scrolling feature for the timeline interface is determined based on the number of fingers, finger movement speed, and/or finger direction associated with the touch input. Consequently, the timeline interface and associated data collection is adjusted in accordance with the determined zoom classification level and/or scrolling feature.
