Abstract: A mobile video game uses real world anchor points in providing for video game play which includes virtual elements. The real world anchor points may be specified in terms of a geographic coordinate system, and game play may be based on mobile device presence at or about the anchor points.

Abstract: A virtual game world may have game locations based on electronic devices with communications capabilities. In some embodiments electronic devices with communications capabilities are identified to a server, which forms a game location for the identified devices, or at least some of them. The game locations may have non-player controlled game characters as inhabitants of the game locations. One or more characteristics of the inhabitants of a game location may be based on an aspect relating to the electronic device with communication capability with which the game location is associated.

Abstract: A sacrificial barrier for use along a highway, usually arranged in an array of such barriers for causing a relatively rapid deceleration and stopping of a vehicle to prevent substantial injury to the vehicle and the occupant thereof. The barrier comprises a container body, a new, improved frangible support table within the body and a quantity of a dispersible mass supported on the support table. One or more spacers may be used under the table for barriers designed to maintain a constant center of gravity when using smaller quantities of dispersible mass.
