Abstract: The described technology is generally directed towards pull locomotion, which allows users to move around a virtual reality environment (typically larger than their physical environment) by interacting with pull targets, which comprise interactive objects displayed in the reality environment. When (e.g., via a controller) the user reaches grabs a pull target and pulls the controller back towards the user, the user's perceived position moves toward the target, as if the environment is being pulled to the user. A push motion generally results in moving the user's perceived position away from the target. The perceived movement can be gradual in the environment, relative to the speed of the pull or push. The pulling and pushing facilitate an interactive narrative experience or enhance interactive game play.

Abstract: A high pressure gas flare using the Coanda effect has a noise attenuator surrounding the high pressure gas outlet slot. The noise attenuator is in the form of one or more upwardly diverging frusto-conical shields which may be spaced apart or closed with the body of the flare. The attenuator is particularly useful for steam driven flares.
