US Classification:

359584, 359587, 359580, 359578, 359577

Abstract:

An electromagnetic wavelength filter that allows the transmission of electromagnetic energy within a narrow range of wavelengths while reflecting incident electromagnetic energy at other wavelengths. The filter includes at least one cavity region; and at least two reflectors surrounding the at least one cavity region, at least one of the reflectors being an omni-directional reflector. The omni-directional reflector includes a structure with a surface and an index of refraction variation perpendicular to the surface, and the omni-directional reflector is specifically configured to exhibit high omni-directional reflection for a predetermined range of frequencies of incident electromagnetic energy for any angle of incidence and any polarization.

Abstract:

Context-specific user interfaces, e.g., for use with a portable multifunction device, provide, inter alia, indications of time and, optionally, a variety of additional information. A user interface screen including a current time indicator and a first platter is displayed. The first platter is at a first position, is associated with a first application, and displays a first set of information obtained from the first application. The first set of information relates to a first temporal context of the current day. In response to detecting a user input, the first platter is displayed at a second position and a second platter is displayed at the first position. The second platter is associated with a second application and displays a second set of information obtained from the second application. The second set of information relates to a second temporal context of the current day.

International Classification:

G06T 7/579
G06T 7/246
G06V 10/44
G06V 10/74

Abstract:

A method includes receiving a first image, receiving a motion dataset, determining a motion level, determining an initialization state, and determining a tracking level. In a first condition, the method includes generating a first image pyramid, detecting a plurality of features in the first image pyramid using a first detector threshold, and generating a first set of detected keypoints from the plurality of features. In a second condition, the method includes generating a second image pyramid, detecting the plurality of features in the second image pyramid using a second detector threshold, the second detector threshold being less restrictive than the first detector threshold, and generating a second set of detected keypoints. In a third condition, the method includes detecting the plurality of features in the first image according to the first detector threshold and generating a third set of detected keypoint.

Abstract:

Systems, methods, and devices can allow applications to provide complication data to be displayed in display of an electronic device. A client application can create a data object according to a template to efficiently select how the data object is to be displayed. For example, a complication controller on the electronic device can receive new data and determine which template to use. The data object can be sent to a display manager that can identify the selected template and display the data according to the template.

Abstract:

The present disclosure generally relates to providing time feedback on an electronic device, and in particular to providing non-visual time feedback on the electronic device. Techniques for providing non-visual time feedback include detecting an input and, in response to detecting the input, initiating output of a first type of non-visual indication of a current time or a second type of non-visual indication of the current time based on the set of non-visual time output criteria met by the input. Techniques for providing non-visual time feedback also include, in response to detecting that a current time has reached a first predetermined time of a set of one or more predetermined times, outputting a first non-visual alert or a second non-visual alert based on a type of watch face that the electronic device is configured to display.
