Abstract: The invention provides an omnidirectional treadmill system that uses an inner core which is inflated within a tread membrane. On the outside surface of the inflated inner core are ball casters which push outward against the interior of the membrane, resulting in a low friction barrier between the inner core and the inside surface of the tread membrane. The tread membrane rests on a sphere directly below the user in the center of the device. When the sphere is rotated it drives the tread around the stationary inner core. The sphere rotation is accomplished using a holonomic drive system such as motorized omni wheels. The device uses an enclosure which encircles the tread area. The enclosure serves two purposes: to enhance safety of the user and to provide a surface for image projection to the user in virtual reality applications.

Abstract: A small electronic device used to perform alignment of a lined golf ball in preparation for putting. The device is battery powered and includes one or more motors for rotating the golf ball at a high speed. The device further includes one or more photonic line sensors disposed at the golf ball for identifying the line on the golf ball and for communicating with a microcontroller which coordinates the electric rotation motors to align the golf ball to the device. The electronic device also features a mechanical loading mechanism which holds the golf ball for rotation during the alignment process and releases the golf ball to the putting green without rotation when alignment is complete.

Abstract: A method of the invention comprises generating a display of privilege state data for a network system in a three-dimensional view. The privilege state data can include graphical symbols indicating “on”, “inherited on”, “public on”, “off”, “not set”, and “disabled” states. The display can include at least one privilege label, object label, and user label arranged along respective axes of the three-dimensional view. The privilege state data can be displayed one or more cells arranged in association with respective privilege label(s), object label(s), and user label(s). The privilege label identifies at least one privilege, the object label identifies at least one object associated with the privilege, and the user label identifies at least one user or group of users associated with the object.
