Abstract: An embodiment of a method for compensating variations in an attenuation of light of an optical filter of a light sensor system comprises illuminating a clear sensor and a color sensor of the light sensor system with a test light having a test spectrum. Therein the color sensor comprises the optical filter and is designed to predominantly sense light with a wavelength within a pass band of the filter; and the test spectrum has components outside the pass band. A clear test signal generated by the clear sensor and a color test signal generated by the color sensor are received in particular in response to the illumination with the test light. Then a first transmission value T is determined based on the clear test signal and on the color test signal. Finally, a compensation factor Kr, Kg, Kb is calculated to compensate the variations in the attenuation of light based on the first transmission value T and a nominal transmission value Tn of the filter.

Abstract: A control system for a gesture sensing arrangement with at least one sensor operates the sensor in a proximity mode. The control system receives data sets generated by the sensor and based on these data sets determines whether an object is present in a vicinity of the sensor. When an object is detected in the vicinity the control system operates the sensor in a gesture mode. Based on further data generated by the sensor the control system determines an end of a gesture, and operates the sensor in the proximity mode.

Abstract: An improved user interface is provided for displaying selectable software functionality controls of a database application. When a task-based functionality tab is selected from the user interface, selectable functionality controls provided by the associated database application for performing aspects of a task related to the selected tab are presented in a ribbon-shaped user interface above a workspace in which a user is entering or editing data. Upon selection of a different task-based functionality tab, the presentation of functionality controls associated with the first task is removed, and selectable functionality controls associated with the second selected task-based functionality tab are presented in the user interface. The selectable functionality controls presented in the user interface are grouped into logical groupings for more efficient utilization.

Abstract: A projection apparatus for the enlargement of photos and sketches constructed integrally within a small tent so that it may be used without requiring a darkened room for projecting. The tent is placed upon a suitable table and has an opening on one side for accessing its interior. The projection system requires that the photo or sketch be traced onto a clear plastic sheet which is then placed onto a transparent platform located somewhere between a miniature lamp and the projection surface. When the lamp is turned on, an enlarged shadow of the traced image is seen on the projection surface and is then traced onto it. Varying the projected enlargement is achieved buy sliding the lamp holder up and down a linear slide.
