Abstract: Technologies are described for suppressing the collection of activity data by an operating system. An operating system provides an application programming interface (“API”) through which applications can submit activity data. The activity data can be exposed to users through a UI that includes UI controls that can be selected to resume previously performed activities. The operating system also provides another UI that includes UI controls for specifying that collection of activity data by the operating system is to be suppressed. When the UI control is selected, the API will discard activity data received from applications. Another selection of the UI control will instruct the API to resume collection and storage of activity data provided by the applications. The UI for suppressing the collection of activity data can also include another UI control which, when selected, will cause activity data previously obtained by the API and stored to be discarded.

Abstract: Technologies are described for resuming activities using activity data collected by an operating system. An operating system provides an application programming interface (“API”) through which applications can submit activity data. The activity data identifies an application and an activity previously performed using the application. The activity data can be presented to users in a UI that includes UI controls corresponding to the reported activities. The UI controls can identify the activity and the application used to perform the activity. The UI controls can be presented in an order determined based upon the time at which the corresponding activity was performed. The UI controls can be selected to resume the corresponding activity. Functionality can also be provided for scrolling through the UI controls, searching the activity data, filtering the represented activities, deleting the activity data corresponding to an activity, and performing other functions.

Abstract: A lens unit (120) shows longitudinal chromatic aberration and focuses an imaged scene into a first image for the infrared range in a first focal plane and into a second image for the visible range in a second focal plane. An optical element (150) manipulates the modulation transfer function assigned to the first and second images to extend the depth of field. An image processing unit (200) may amplify a modulation transfer function contrast in the first and second images. A focal shift between the focal planes may be compensated for. While in conventional approaches for RGBIR sensors contemporaneously providing both a conventional and an infrared image of the same scene the infrared image is severely out of focus, the present approach provides extended depth of field imaging to rectify the problem of out-of-focus blur for infrared radiation. An imaging system can be realized without any apochromatic lens.

Abstract: An optoelectronic component including an optical waveguide, an integrated optical resonator, in which the waveguide or at least a portion of the waveguide is arranged, and a heat source which can increase the temperature of the resonator during operation. A web region adjoins laterally the waveguide when viewed in the longitudinal direction of the waveguide. The web region forms a jacket portion of the waveguide and has a smaller thickness than the waveguide. The heat source is thermally connected to the waveguide by means of the web region.

Abstract: A lens unit of an imaging unit features longitudinal chromatic aberration. From an imaged scene, an imaging sensor unit captures non-color-corrected first images of different spectral content. An intensity processing unit computes broadband luminance sharpness information from the first images on the basis of information descriptive for imaging properties of the lens unit. A chrominance processing unit computes chrominance information on the basis of the first images. A synthesizing unit combines the computed chrominance and luminance information to provide an output image having, for example, extended depth-of-field. The imaging unit may be provided in a camera system, a digital microscope, as examples.
