Abstract: Methods, systems, and computer programs for generating revenue in an online game are presented. One method includes an operation for creating, in the online game, a first virtual currency and a game score, where the amount of the first virtual currency can be increased in exchange for real currency. The first virtual currency can be traded for advancement in the online game. Further, a game module, that is an autonomous game within the online game, is started, and a second virtual currency and a module score are created in the game module. The amount of the second virtual currency can be increased in exchange for real currency, where the second virtual currency can be traded for advancement in the game module and cannot be traded for advancement in the online game outside of the game module. Advancement in the game module increases the module score and does not increase the game score.

Abstract: A method for performing a social project in a video game is provided. A session of the video game for a primary user is initiated, and a social project is initiated within the session of the video game. One or more secondary users are determined from a social graph of the primary user. A message requesting help to complete the social project is sent to the one or more secondary users, the message including a low-friction response mechanism. Upon activation of the low-friction response mechanism of the request, a response is received indicating an intent to help complete the social project from a responsive secondary user. Upon receiving the response, automated retrieval and animation of an avatar of the responsive secondary user is triggered within the primary user's session of the video game so as to collaborate on the social project.

Abstract: A dental implant unit includes a layer of synthetically created titanium dioxide. The dental implant unit has one end for connection and a lateral surface covering the implant unit except for the end for connection. The lateral surface includes a layer of synthetically created titanium dioxide while the end for connection is free from synthetically created titanium dioxide. Also, a method produces a whitened implantable dental unit. The method includes thermal oxidation of a dental implant unit that includes titanium.

Abstract: The invention relates to a foldable head rest assembly (1) for a vehicle comprising a bracket (3), an armature (5) for carrying a head rest, a locking mechanism (33) and a release mechanism, wherein the armature comprises a first arm, which is mounted to the bracket by an armature shaft (17) and pivotable with respect to the bracket about a first axis (18) between an upright position and a folded position, wherein the first axis is defined by the armature shaft, wherein the locking mechanism (33) prevents pivoting of the armature from the upright position to the folded position and wherein the release mechanism (49) can move the locking mechanism from a locked position to an unlocked position, characterized in that an abutment surface (34) of the first arm abuts a locking shaft (31) in the upright position, the locking shaft extending along a second axis that extends parallel to and spaced apart from the first axis, and the release mechanism is mounted to the locking shaft (31) and pivotable about the second

Abstract: Methods, systems, and computer programs for creating a crew to participate in a mission challenge in an online game includes identifying quests to complete the mission challenge. Each quest includes a plurality of tasks and each task includes a plurality of subtasks. A request feed is sent to members of a social graph of a user requesting the members to join the crew and to participate in completing the subtasks of the challenge. Skill set associated with each member of the social graph responding to the request feed is determined and matched with the skill set required for completing each subtask. A distinct subtask is delegated to each member based on the match. Each crew member's progression in completing the challenge is monitored and managed based on the progression made in the delegated subtask. Status of the challenge is updated and shared with the members of the crew.

Abstract: Software at a massively multiplayer online (MMO) game website receives a request for assistance with a game task from a first player of a MMO game. The software transmits the request to a second player of the MMO game who is associated with the first player through a relationship recognized by the MMO game. The software determines whether the second player responds to the request within a time period. The time period depends on one or more factors related to game mechanics and to user data for the first player. Then if the second player does not respond within the time period and the game task is a game task whose completion can be assigned without the assistance of another player, the software assigns completion of the game task to the first player and transmits an automated apparent response to the first player.

Abstract: The invention provides an antenna arrangement for a radar system arranged for coverage of a surveillance area and comprising antenna elements. The antenna elements are arranged to receive a signal transmitted from a transmit antenna of a transmit antenna arrangement and reflected by a target towards the antenna arrangement wherein: • the antenna arrangement comprises at least two non-parallel line arrays, • each antenna element being connected to a receiver where each line array is arranged to create, by using digital beam forming, beams for instantaneous coverage of at least said surveillance area and • within the surveillance area said line arrays are arranged to allow the target position to be limited to one or two crossing areas between at least two beams from different line arrays from which target reflections have been received. The invention also provides a corresponding method and a radar system comprising the antenna arrangement.

Abstract: The present invention describes particles of titanium, titanium alloy, at least one type of titanium oxide or a combination thereof, wherein at least a substantial amount of the particles are of micrometer-millimeter size and are non-spherical, for use as an X-ray contrast agent. The irregular shapes and/or internal pores and cavities of said particles lead to a prolonged retention time in the gastrointestinal tract leading to a longer time period available for X-ray examination. Further, the particles are not only chemically inert, they also exhibit an anti-inflammatory and anti-bacterial effect on the surrounding tissue.

Abstract: An apparatus for preventing blood exposure or contamination upon withdrawal of a hypodermic needle is provided. The apparatus may include a needle having a tip and a shield configured to at least partially entrap the needle tip upon withdrawal of the needle. The apparatus may further include a blood stabilizing material disposed such that upon withdrawal of the needle the blood stabilizing material is disposed in operative association with the needle tip such that blood carried by the needle is prevented from escaping the apparatus. In some exemplary implementations, the blood stabilizing material may be disposed on one or more surfaces of the shield. The shield of the hypodermic needle may include protective device and/or a housing for shielding the needle tip upon withdrawal. The housing may be adapted to at least partially cover the needle tip upon withdrawal of the needle.
