Abstract: A method for moving and orienting an object in a virtual reality or augmented reality environment that uses a movement tool with multiple states that correspond to the actions that a user may take to manipulate the object. The movement tool may have a stored position and orientation that are applied directly to the object without the need for user input; if these parameters are not stored, the movement tool may enter a moving or placing state, and/or an orientation state where the user can set the position or orientation, respectively. Additional movement tool states may include a rotation state and a translation state. State-specific guides or controls may be shown in certain states of the movement tool. These tools may enable a user to perform accurate and intuitive actions to move, scale or rotate an object in an n-dimensional space with millimeter precision.

Abstract: A filter element for the separation of dust particles from a gas flow or air flow. The filter element includes a number of filter pockets and a main support frame, the open mouth edges of the filter pockets being interconnected to the main support frame and its interconnecting traversing ribs. This design of the filter element results in a substantial increase in the usage values of the materials involved and favorably contributes to present high environmental standards, at lower long term system costs. This is achieved by using a main support frame which includes interfitting subframes that are detachably connected one to another and to the filter pockets.
