Patent number: 6689012Abstract: A continuously variable transmission is disclosed for use in rotationally or linearly powered machines and vehicles. The transmission provides a simple manual shifting method for the user. Further, the practical commercialization of traction roller transmissions requires improvements in the reliability, ease of shifting, function and simplicity of the transmission. The present invention includes a continuously variable transmission that may be employed in connection with any type of machine that is in need of a transmission. For example, the transmission may be used in (i) a motorized vehicle such as an automobile, motorcycle, or watercraft, (ii) a non-motorized vehicle such as a bicycle, tricycle, scooter, exercise equipment or (iii) industrial equipment, such as a drill press, power generating equipment, or textile mill.Type: GrantFiled: April 25, 2002Date of Patent: February 10, 2004Assignee: Motion Technologies, LLCInventors: Donald C.

Patent number: 6676559Abstract: A continuously variable transmission. The transmission includes a plurality of power adjusters, such as spherical balls, frictionally interposed between a driving and a driven member. The driving and the driven member are each rotatably disposed over a main shaft. The spherical balls are configured to rotate about a modifiable axis and thereby provide a continuously variable shifting capability by adjusting the ratio between the angular velocity of the driving member in relation to the driven member. The system includes automatic and manual shifting gearing for adjusting the speed of the transmission. The system also includes a support a support member which is rotatably disposed over the main shaft and frictionally engaged to each of the spherical balls.Type: GrantFiled: October 30, 2001Date of Patent: January 13, 2004Assignee: Motion Technologies, LLCInventor: Donald C.

Patent number: 6612651Abstract: An apparatus is provided for imparting substantially oscillatory horizontal motion to a subject. The apparatus has a translating support assembly, an oscillatory mechanism, and an actuator permitting the subject to apply a non-gravitational acceleration to the translating support assembly. The oscillatory mechanism has a linkage assembly with mounts offset in a plane transverse to the direction of motion so as to permit a large stroke of travel of the translating support assembly relative to a fixed support structure. Additionally, a locking mechanism is provided that is biased to preclude motion of the oscillatory mechanism in the absence of a substantial weight on the support assembly.Type: GrantFiled: July 20, 2001Date of Patent: September 2, 2003Assignee: Motion Technology, LLCInventor: Thomas A.

Patent number: 6608408Abstract: A linear electromagnetic machine for generating a force acting between two members relatively movable along an axis, one of which is capable of producing a magnetic field the direction of at least part of which extends substantially radially of the said axis and the other of which comprises or includes a conductor, conveniently in the form of a coil, in which an electric current can flow substantially perpendicularly of the magnetic field so as to generate a force between the two members substantially parallel to the axis. The radial magnetic field is generated by permanent magnets orientated with their direction of magnetization axially, the pole pieces acting to concentrate the magnetic flux to follow a radial path through the coils.Type: GrantFiled: June 14, 2000Date of Patent: August 19, 2003Assignee: Advanced Motion Technologies LLCInventor: Phillip Raymond Michael Denne

Patent number: 6588289Abstract: A contamination resistant lead screw or ball screw-driven linear actuator has the lead screw and drive nut enclosed within a specially constructed guide chassis. A carriage is slidably mounted on parallel rails attached to the guide chassis. The carriage is attached to the drive nut through a slot in the guide chassis. An enclosure surrounds the guide chassis. The enclosure and the guide chassis create a labyrinth seal that effectively contains internally generated debris and contamination and excludes environmental dirt, debris and contamination.Type: GrantFiled: July 6, 2001Date of Patent: July 8, 2003Assignee: Danaher Motion Technology, LLCInventors: Tom Thang Ung, Robert Alexander Lipsett

Patent number: 6551210Abstract: A continuously variable transmission is disclosed for use in rotationally or linearly powered machines and vehicles. The single axle transmission provides a simple manual shifting method for the user. An additional embodiment is disclosed which shifts automatically dependent upon the rotational speed of the wheel. Further, the practical commercialization of traction roller transmissions requires improvements in the reliability, ease of shifting, function and simplicity of the transmission. The disclosed transmission may be used in vehicles such as automobiles, motorcycles, and bicycles. The transmission may, for example, be driven by a power transfer mechanism such as a sprocket, gear, pulley or lever, optionally driving a one way clutch attached at one end of the main shaft.Type: GrantFiled: May 7, 2002Date of Patent: April 22, 2003Assignee: Motion Technologies, LLC.Inventor: Donald C.

Patent number: 6468082Abstract: An apparatus for imparting motion to a load comprises means for applying a force to the load and a compliant support for the load, in which there are provided means for effecting dynamic variation of the compliance of the support during operation of the apparatus so as to optimise the power efficiency. The apparatus may be capable of controlling relative motion in a plurality of degrees of freedom between a platform and a reference plane, the compliant means acting to support the weight of the platform, and the force-applying means being one or more actuators for applying perturbing forces between the platform and the reference plane. Control means act to control one or more actuators to move in one direction or the other to displace the platform with respect to the reference plane. At least part of the compliant supports may be a gas spring and in one embodiment this is in the form of a bellows supporting the platform.Type: GrantFiled: March 17, 2000Date of Patent: October 22, 2002Assignee: Advanced Motion Technologies, LLCInventor: Phillip Raymond Michael Denne
