Abstract: A method and a system for predicting churn of a player of an online game is described. Online engagements of a group of players of the online game are monitored during a churn prediction model training period. Online engagement scores for the group of players are computed within a periodic number of days within the churn model training period. A weighted exponential moving average of the online engagement scores of the group of players of the online game is computed during the churn model training period. The weighted exponential moving average is used to determine an online engagement threshold value of a churn prediction model for the online game. The online engagement threshold value is applied to a weighted exponential moving average of a player during an observation period to determine a churn probability of the player within a prediction period.

Abstract: A short-range wireless architecture is presented that allows a wireless user device, such as a personal digital assistant, to communicate and enter into transactions with an application server or back-end device. A wireless tier is utilized, which may provide services for the wireless user device such as security and authentication, session and context management, proxy services, service aggregation ad home page/portal services. The wireless tier may store context and/or session information for the wireless user device, and may be used to filter information sent to a wireless device from an application server. The wireless tier may login/logout the user device to an application server automatically, and may provide user and/or personalization information to the application server. The wireless server may also pre-stage information to enhance the user experience, and may maintain state information in the event of a temporary loss of wireless communication.

Abstract: A method for providing user-apparent consistency in a wireless user device is presented. An IP address, or other unique identifier, is assigned to a wireless user device in wireless communication with a wireless application server. The IP address is associated with a communication session between the wireless user device and the wireless application server. The IP address, along with information related to the communication session, such as context information, is stored by the wireless application server, such as in an active session cache. The wireless user device may then rejoin the communication session in the event the wireless communication is temporarily dropped and re-established between the wireless user device and the wireless application server, without losing the assignment of the IP address to the wireless user device or any information stored for the IP address in the active session cache.

Abstract: An apparatus for semiautomatic classification of volume data provides the ability to generate visually significant representations of the important regions of the data set. The representations may be indicated by opacity or color changes, for example. The apparatus comprises programming to compute a two-dimensional (2D) histogram over a volume of scalar values, ƒ, versus edge values edge( ). A common edge value is the gradient magnitude, edge ( )=|?ƒ|.

Abstract: A method for suggesting products to a user of a wireless user device is presented, which may also allow the user to purchase those products through the wireless device. Historical information stored for the user may be used to query a back-end device for a selection of products. The selection of products may be based upon the historical information, such as may include recent purchases of product viewing history. The selection of products may then be filtered, formatted, pushed to a display on the wireless user device. The user may then purchase these products by selecting them on the wireless user device.

Abstract: A windscreen wiper comprises two wiper blades and a bridge structure for coupling the wiper blades, which bridge structure is a light weight profiled structure and comprises two longitudinal bars which run parallel to and in the longitudinal direction of the wiper blades and are designed uncurved with respect to the wiper blades and connected to each other by cross connecting webs.

Abstract: A plurality of molding boxes having a common center line are disposed in an aligned manner in a horizontal guideway located, in the direction in which pressure is exerted and expulsion is effected, between a pressure piston and an outwardly pivotable pressing device and the molding devices are displaceable in the guideway. One pattern carrier plate is provided between each of the individual molding boxes, and the pattern carrier plates can be moved in and out when the molding boxes are apart. A tilting device is disposed at the outlet of the machine, which selectively either allows pressed mold bodies to pass by it with the position of their seams unchanged, or tilts the mold bodies, pressed in pairs, by an angle of 90.degree..
