Publication number: 20140182169Abstract: The invention herein is directed toward footwear containing a central flex zone comprised of a novel combination of a central flex channel with a central flex element that imparts either bidirectional or multi-directional flexion to the shoe, according to various embodiments, thereby allowing more natural flexibility and allowing all surface contacting members to independently engage and disengage from the contact surface of the user as the wearer's weight shifts. The flex zones also naturally adapt to the amount of stress put on the sole from ground elements, such as rocks or branches that the sole encounters during wear and to adjust to different terrain due thereby being particularly useful in applications such as construction boots and athletic footwear.Type: ApplicationFiled: December 27, 2012Publication date: July 3, 2014Inventor: Michael MACK

Patent number: 8035117Abstract: A light emitting diode (LED) grown on a substrate doped with one or more rare earth or transition elements. The dopant ions absorb some or all of the light from the LED's active layer, pumping the dopant ion electrons to a higher energy state. The electrons are naturally drawn to their equilibrium state and they emit light at a wavelength that depends on the type of dopant ion. The invention is particularly applicable to nitride based LEDs emitting UV light and grown on a sapphire substrate doped with chromium. The chromium ions absorb the UV light, exciting the electrons on ions to a higher energy state. When they return to their equilibrium state they emit red light and some of the red light will emit from the LED's surface. The LED can also have active layers that emit green, blue and UV light, such that the LED emits green, blue, red and UV light which combines to create white light.Type: GrantFiled: July 10, 2006Date of Patent: October 11, 2011Assignee: Cree, Inc.Inventors: Steven P.
