Abstract: A social networking system comprises a mobile telephone device relating to a first user. that facilitates telephone calls between the first user and other users. User data including identity data and contact data of the other users is initially resident upon the mobile telephone device. The mobile telephone device comprises a resident client application, a social network server and a network providing communication between the mobile telephone device and the social network server. User data is obtained from the device and transmitted to the social network server. The social network server analyzes the user data to identify which other users are also users of the social network server and to form a social network group accordingly and to receive update data relating to any user of the group. The social network server further selects the update data and transmits it to the client application for presentation to the first user.

Abstract: An image presentation device (100) includes a set of color light sources (122, 124, 126) and a micro-display panel (150) capable of operating in both image processing and non-image processing modes. A sensor (170) is coupled to the micro-display device (150) to convert light received from the light source (122, 124, 126) into a signal value representing the output from the light source (122, 124, 126). A controller (110), responsive to the signal value, selectively and/or collectively varies the input to each of the individual light sources (122, 124, 125) to provide for consistent operating performance over the life of the product.

Abstract: An image presentation device (100) includes a microdisplay panel (150) and a set of light sources (122, 124, 126) operable to emit light of different colors. An optical structure (140) couples the set of the light sources (122, 124, 126) to the microdisplay panel (150). A controller (110) is responsive to the data obtained from an analysis of each image frame, to selectively and individually vary output intensity for the light sources (122, 124, 126) to achieve a particular illumination level and corresponding ratio for processed images.
