Abstract: An example robot includes a first actuator and a second actuator connecting a first portion of a first member of the robot to a second member of the robot. Extension of the first actuator accompanied by retraction of the second actuator causes the first member to roll in a first roll direction. Retraction of the first actuator accompanied by extension of the second actuator causes the first member to roll in a second roll direction. A third actuator connects a second portion of the first member to the second member. Extension of the third actuator accompanied by retraction of both the first and second actuators causes the first member to pitch in a first pitch direction. Retraction of the third actuator accompanied by extension of both the first and second actuators causes the first member to pitch in a second pitch direction.

Abstract: A plug that can seal an aperture in a body includes a base, a main plug portion extending outward from the base, a groove body portion extending from a distal end of the main plug portion and having an outer diameter and a cap receiving portion extending from a distal end of the groove body portion and having a smaller outer diameter than the outer diameter of the groove body portion. The plug also includes a cap installed on the cap receiving portion and a radial sealing element disposed between the cap and the distal end of the main plug portion, the radial sealing element having an inner diameter that is larger than the outer diameter of the cap receiving portion. In operation, the cap is installed onto the cap receiving portion after the radial sealing element has been attached.

Abstract: A modular radiator panel includes a coolant tube, a saddle surrounding a first portion of the coolant tube and a radiative sheet mounted to the saddle. The radiative sheet surrounds a second portion of the coolant tube, such that the coolant tube is sandwiched between the radiative sheet and the saddle. A radiator includes a plurality of coolant tubes and saddles. Each saddle surrounds a first portion of a respective one of the coolant tubes. The radiator includes a plurality of radiative sheets. Each radiative sheet is mounted to a respective one of the saddles. Each radiative sheet surrounds a second portion of a respective one of the coolant tubes, similar to the radiative sheet described above.

Abstract: A method and system for hosting an online virtual world system on game engine servers, is provided. One implementation involves obtaining a map representing a virtual world in the game, partitioning the map into multiple partitions, and selecting a game engine server for each partition as responsible for executing the game for detected game entities in that partition, wherein the selection is based on load balancing between the game engine servers.

Abstract: A method and apparatus for hosting a virtual world system including clients and game engine servers, is provided. One implementation involves providing a publication and subscription framework, interfacing the clients with the framework using a plurality of client proxies, interfacing each game engine server with the framework using a game engine agent, and decoupling the proxies from the game engine servers using the framework.
