| 20100199791 | TETRAHEDRON RACK AND PINION DRIVE - A spindle assembly drive system that includes a rack unit, a drive gear, a motor, and a plurality of bearings, such that said rack unit laterally moves in a first axis with little or no movement in or rotation about any other axis. | 08-12-2010 |

| 20080247173 | LENS SYSTEM FOR LED LIGHTS - An optical device for distributing light produced by a white LED or other light-producing device includes a lens portion that refracts the light to provide a desired light intensity distribution, and a collimating portion that internally reflects light from the white LED. The optical device may be molded from an acrylic polymer material or the like. The reduced thickness of the device facilitates low cycle times and reduces warpage or other distortion that would otherwise be generated during the molding process. | 10-09-2008 |

| 20090153967 | OPTICAL SECURITY DEVICE OFFERING 2D IMAGE - The present invention provides for a diffractive element comprising a diffractive optical microstructure consisting of a modulated structure of a diffractive type which upon illumination by diffused ambient light creates a two-dimensional image to be viewed by an observer upon tilting or rotating the device or by varying lighting direction, wherein the diffractive modulated structure of the device consists of various generally parameterised special optical elements with specifically prescribed groove shapes, wherein each groove shape, position, centre(s), and line thickness, are described by functions describing those dependencies which are variables of the positional coordinate of the optical element. | 06-18-2009 |

| 20090260934 | SHOCK ABSORBER HAVING RESILIENT DEVICE IN REBOUND CHAMBER - A shock absorber comprises a damping cylinder pressurized by a system pressure and divided by a piston into a compression chamber and a return chamber. A resilient device is disposed in the return chamber. The resilient device comprises a pressurizing member or pressurizing medium disposed in an inner volume that is delimited from the return chamber. The resilient device acts upon the damping medium volume in the return chamber such that the pressure initially during a compression stroke does not fall below a predetermined minimum pressure. As long as the pressure in the return chamber is less than the pressure created by the resilient device, the device is able to absorb energy. When the pressure in the return chamber is greater than the pressure created by the resilient device, the device becomes inflexible. The resilient device compensates for pressure reduction in the return chamber that occurs under rapid damping movements and that can cause cavitation during a compression stroke. | 10-22-2009 |
| 20110017558 | SHOCK ABSORBER WITH INCREASING DAMPING FORCE - A vehicle shock absorber generates an additional counter-force acting counter to the direction of movement near the limit position of movement. The shock absorber substantially comprises a damping medium-filled damping cylinder that is divided into two damping chambers by a main piston. The main piston is axially moveable relative to the damping cylinder and is attached to a piston rod. A second piston/damping piston that contains one or more first and second through-ducts is mounted to the piston rod. The ducts are defined by first and second flow-limiting devices such as multiple thin washers. The damping piston slides in a restricting space located in the damping cylinder. The restricting space has an inside diameter smaller than the inside diameter of the damping cylinder. The additional counter-force is substantially constant throughout the entire stroke in order to create gentle braking of the damping movement. | 01-27-2011 |
