Abstract: A display arrangement comprises an image display device having two or more sets of images for display; a camera directed towards positions adopted by users viewing the display; a face detector for detecting human faces in images captured by the camera, the face detector being arranged to detect faces in at least two face categories; and means, responsive to the a frequency of detection of categories of faces by the face detector at one or more different periods, for selecting a set of images to be displayed on the image display device at that time of day.

Abstract: The invention relates to the use of composite material which comprises nanoparticles of a least one metal derivative and at least one organic sunscreen agent which is chemically bound with said particles in a covalent manner in the form of an ultraviolet radiation protective agent containing the inventive composite material. Cosmetic ultraviolet radiation protective compositions comprises said mixture are also disclosed.

Abstract: Methods for apportioning revenue in an online game-playing community include: maintaining a trait summation ladder, the trait summation ladder comprising a hierarchy of player communities, each player community comprising one or more player groups all having a given trait; receiving a request from a user to play an online game, wherein the user is a member of a player group comprising one or more players sharing a given trait; receiving a request from the user to play a session of the online game in a forum corresponding to a given community, wherein the community includes the user's player group; computing an amount of revenue derived from the player during the session; and determining, based on a level of the given community within the trait summation ladder, a given percentage of the revenue amount to allocate to the player group. Corresponding systems are also described.

Abstract: The present invention provides a method for reducing the immunogenicity of a peptide or protein, which method comprises the steps of designing a series of overlappig test peptides each having an amino acid sequence that corresponds with part of the amino acid sequence of the peptide or protein of which the immunogenicity is to be reduced; identifying which of the test peptides of the series comprises one or more T-cei epitope(s); modifying the amino acid sequence of one or more of the test peptides comprising one or more T-cell epitope(s); repeating some of the steps with the modified test peptides until one or more of the T-cell epitopes originally comprised therein are significantly reduced or eliminated; modifying the amino acid sequence of the peptide or protein of which the immunogenicity is to be reduced according to the T-cell eliminating modifications made in the amino acid sequence of the test peptides to produce a modified peptide or protein.

Abstract: A system and method for delivering short messages to idle mobile stations which conserves paging channel capacity. A normal page is first sent to all cells to locate the mobile station to which the short message is addressed. When the mobile station is located, the full short message is sent over the paging channel for the single cell in which the mobile station is located if the length of the short message is determined to be suitable for sending over the paging channel. If the short message is too long, then a traffic channel is established to the mobile station, and the message is sent over the traffic channel.
