A method, apparatus, and a computer program is provided. The method comprises: determining an ambient light value from ambient light data provided by at least one ambient light sensor, in dependence upon the spectral distribution of the ambient light data provided by the at least one ambient light sensor and a manufacturer of the at least one ambient light sensor.

Ambient light detection and data processing

An apparatus including a housing defining at least one interior cavity; at least one optical sensor located within the at least one interior cavity of the housing adjacent a first portion of the housing; wherein the first portion of the housing includes a plurality of distributed optical windows through the housing. A housing part of an apparatus including a housing wall comprising a plurality of distributed micro-windows through the housing wall.

Housing for an optical sensor with micro-windows and a light valve to prevent reflected light from escaping

A method, apparatus, computer program product, and user interface provide for determining a minimum and optimum font size for information displayed on a display based on a predetermined set of criteria, and automatically adjusting the displayed information on the display using a module such that a size of a smallest font of the information is not smaller than the minimum font size and that a size of a main font of the information is not smaller than the optimum font size.

Automatic zoom for a display

A method, apparatus, user interface and computer program product include the ability to determine a brightness characteristic of a display, use the brightness characteristic to determine a minimum and optimum font size for information displayed on the display, and automatically adjust the displayed information such that a size of a smallest font of the information is not smaller than the minimum font size and that a size of a main font of the information is not smaller that the optimum font size.

A layered light guide structure has a number of planar light guides arranged in a stack to receive a number of different color light beams from the edge of the light guides. Each of the planar light guides has one or more diffractive structures imparted or provided on its upper surface. The diffractive structures on each light guide are configured to diffract light of a particular wavelength range so that they efficiently diffract the guided light within that light guide. The diffractive structure can be one or more keypad symbols such that the layered light guide structure can be used as a keypad. The symbols can be pixelized such that the pixels can have different color patterns. The diffractive structure can also be a simple patch so that the layered light guide structure can be used as a back-light source.
