Abstract: The invention provides a dispersion compensation system and method formed by cascading a series of GT cavities with three setting parameters, reflectivity, resonant wavelength, and free-spectral-range. In one aspect of the invention, the GT cavities can synthesize any shape of combined dispersion compensation, including positive, negative, slope dispersion compensation. In another aspect of the invention, the GT cavities are tunable or dynamic to accommodate various types of dispersion compensation. Advantageously, the present invention provides an effective cost solution for a more precise dispersion compensation tuning.

Located on these protrusions are reflective patches. A hood can be removably secured to the vest.

Abstract: Flexible retroreflective sheeting, and products therefrom, fabricated from an elastic substantially linear olefin polymer are found to exhibit significantly enhanced retention of retroreflectivity and do not require the addition of plasticizers. The retroreflective sheeting of the invention is a surprisingly good replacement for polyvinyl chloride sheeting which heretofore have shown poor retention of retroreflectivity and have required addition of plasticizers for optimal flexibility and handling.

Abstract: A bicycle rider expandable light reflective strap which can be worn around the arms, legs, waist or wrist of a bike rider. Also, the strap can be used for receipt around the frames or handle bars of a bicycle or scooter. The light reflective strap provides for increase safety when ridding in traffic, at night and when traveling during poor weather conditions. The light reflective strap is expandable and retractable and can be coupled together with another light reflective strap for forming various sizes of a light reflective belt. The bicycle rider expandable light reflective strap or straps include a flexible webbing with one or more parallel light reflective stripes along the length of the webbing. The stripes are used for reflecting light thereon. A first end of the webbing is attached to a first female attachment buckle, A second end of the webbing is looped through a portion of a first male attachment buckle and attached to a webbing length adjustment slide.

Abstract: A reflector belt, which includes a light reflecting frame belt having an elongated base and a light reflecting layer covered on the elongated base, a flexible cover strip covered on the light reflecting layer of the light reflecting frame belt and fastened to two opposite end pockets at the light reflecting layer, and a LED circuit retained between the flexible cover strip and the light reflecting frame belt, the LED circuit having a plurality of LEDs respectively inserted into respective through holes at the cover strip.

Abstract: A combination backpack and splash guard used by a bicycle rider. The combination is designed to protect the bicycle rider's clothing from water and mud during wet weather and when riding through water and mud puddles. Also, the backpack and splash guard provides for carrying various items when riding a bicycle. Further, the backpack and splash guard includes reflective material and/or reflective tape sewn thereon for providing greater visibility to approaching vehicles under dark conditions. The backpack and splash guard includes an outside waterproof back cover with adjustable reflective shoulder straps and waist straps. The shoulder straps and waist straps are used to secure the back cover to a back of a bike rider. An inside back cover, made of mesh material, is attached to a rear face of the outside back cover with a storage opening between the tops of the outside and inside covers.

Abstract: Dual axis retroreflective articles and methods of using them are disclosed. The retroreflective articles may combine dual axis retroreflection with three axis retroreflection to provide a steady glow due to the three axis retroreflective portions of the article and also provide intermittent or flashing retroreflection as the plane of retroreflection from the dual axis retroreflector passes through or near the light source. The retroreflective articles may also include dual axis retroreflective structures in combination with sparkling reflective structures, as well as dual axis retroreflective structures in combination with both three axis retroreflective structures and sparkling reflective structures. Methods of use include moving the dual axis retroreflective structures to obtain intermittent or flashing retroreflection.

Abstract: An exposed lens retroreflective article 10 has in sequence a layer of microspheres 12, a polymeric intermediate layer 18, a metal reflective layer 16, and a polymeric binder layer 14. Microspheres 12 are partially embedded in the binder layer 14, and the intermediate layer 18 and the metal reflective layer 16 are disposed between the microspheres 12 and the binder layer 14 such that the intermediate layer 18 is in contact with microspheres 12.
