  • Patent number: 6786045
    Abstract: The present invention provides novel engine technologies for power generation and work applications. The engines transform sunlight, heat, or cold, directly into mechanical force. The invention uses a focusing means to apply temperature differentials to a thermally reactive material retained in moveable housings. Said thermally reactive material is mounted in contact with a bearing element configured to apply directional force to said thermally reactive material surface as it changes shape in response to said applied temperature differentials.
    Type: Grant

  • Publication number: 20030226401
    Abstract: The present invention provides methods and apparatus for determining the precise makeup of atomic and molecular structures, as well as providing the capability of modifying said structures. The invention uses induced resonant frequency wave effects to define and modify the electromagnetic, electrical, radioactive, atomic weight, and co-valent bonding characteristics of matter. One embodiment of the present invention may produce directionally controllable magnetic fields in gaseous media that interact with magnetically polarized vehicle surfaces to allow high-speed, highly energy efficient inter-planetary space travel. Another embodiment of the invention may neutralize waste products remaining from nuclear fission power production.

  • Publication number: 20030171144
    Abstract: A gaming apparatus is disclosed that bridges the entertainment gap that currently exists between skill-based video game entertainment and the traditional formats of video games of chance. The present invention as described herein, provides a three dimensional software “world” as the gaming environment, and, through the incorporation of human interface devices, provides the player with the feeling of control experienced when playing a skill-based video game, while maintaining the random outcome requirements of standard video games of chance. In certain circumstances, the present invention may actually provide an element of control over the game outcome, but it is the feeling of control—not necessarily actual control—that provides the unique entertainment value. The present invention also provides a two-way video gaming apparatus for accommodating a plurality of players.

  • Publication number: 20020151363
    Abstract: The invention consists of a method, apparatus, and data structure that allows a player remotely located from wagering devices, such as slot machines, video lottery terminals (VLTs), etc., to make wagers on the wagering devices using funds on deposit in an account. The remote player may establish a communication link to the location where the wagering devices are housed through a remote-access service. After authentication of the player's identity, the player may be provided with a menu of available wagering devices. A wagering device computer network server, preferably coupled to video cameras, may transmit the image of the selected wagering device, or as appropriate, the video output of the wagering device, through telecommunications media, to the player. A pop-up control panel on the player's remote viewing system may provide graphical representations of the game play inputs of the actual wagering device, as well as a graphical display of current funds on account.

  • Patent number: 5901612
    Abstract: A dual axis mechanically actuated motion platform which allows a user to move him or herself through a wide range of angular displacement in two intersecting axes individually or simultaneously by apply manual pressure to a lever in the direction of desired angular displacement. The motion platform is comprised of a base frame, a user support platform mounted on top of a universal joint, and a bearing mounted, preloaded offset linkage system coupled to a joystick lever. The offset linkage system creates enough increased mechanical advantage to move the seat platform in concert with the movement of the joystick lever, providing the user with the feeling of controlling an aircraft and the attendant sensations of pitch and roll motion.

  • Patent number: 5885080
    Abstract: A mechanically actuated motion platform which provides a realistic simulation of the side to side motion experienced while operating a vehicle which is normally steered at its front end. The motion platform is comprised of a base frame coupled through a pivot to a second frame which carries a steering assembly and a operator seat. The steering assembly is coupled though a means for conveying rotational energy to an axle shaft which uses a traction wheel fixedly connected to the axle shaft to effect substantially horizontal movement of the second frame when rotational force is applied to the steering shaft. Also provided is a tiltable operator seat which acts in concert with a spring loaded throttle pedal to impart sensations of acceleration and deceleration to the user.

  • Patent number: 4584896
    Abstract: A multiple axis pivot movement control mechanism includes an actuator operatively connected between the relatively pivotable elements at positions spaced laterally from the pivotal axis. The actuator preferably includes a threaded shaft, a threaded collar received on the threaded shaft and pivotably connected to one of the relatively pivotable elements, a bearing assembly connected to the other relatively pivotable element and rotationally supporting the other end of the shaft and transferring axial forces to its connected relatively pivotable element and a motor which operatively rotates the shaft to create pivoting movement. At least one spring or other force inducing element may be connected between the relatively pivotable elements to apply force to counteract the torque effect created when the center of gravity of the object shifts laterally during pivoting movement.
