Abstract: An article of footwear (10) having an initial contact portion (30) and a medial/forefoot portion (34). The initial contact portion (30) exterior sole surface is formed at a dihedral angle (38) to the sole surface of the medial/forefoot portion (34) such that the heel portion has a minimal thickness of material interposed between the foot (32) and the ground surface (40) at a postero-lateral edge of the sole structure, which means that foot flight continues until the foot moves closer to the ground (40) to delay impact and increase stride length. A high friction interface (72, 172) is provided in a medial/forefoot portion of a shoe insole and low friction interface (74, 174) is provided at the initial contact portion (30) of the shoe insole. The low friction area (72) reduces sharing on foot impact, and the high friction forefoot interface (72, 172) eliminates sliding of the forefoot during foot push-off, to decrease wasted energy. Energy efficient and stride length increase are achieved.

Abstract: An optical device is disclosed wherein a first GRIN lens and a second GRIN lens having their optical axes offset. The first GRIN lens has one or more input ports at an input end. The second GRIN lens is disposed to receive light from the first GRIN lens. A reflecting surface is coated onto a second end face of the second GRIN lens or alternatively is disposed adjacent to the second end face and positioned to reflect an input beam of light launched into the input end face of the first GRIN lens. The reflective surface is at a location where light incident upon it to be returned to the first GRIN lens is collimated.  By placing a filter and third GRIN lens between the first and second lenses double filtering may be achieved at the pass band or pass wavelength of the filter. Furthermore, the more simple arrangement including only first and second lenses provides a means of directing light into and out of the device at different angles or directions with respect to the optical axis of the first lens.

Granted: 2001-07-10
Abstract: An exercise shoe is capable of adapting its fit while being worn.  The shoe has a quarter which is split into an upper portion and a side portion on each side of the shoe.  In the gap between the upper portion and each respective side portion is an elastic gore which will stretch to permit the upper portion and side portions to move apart from each other as the foot moves during exercise or should the foot swell while being worn.  A comfortable fit may be maintained without manipulating the shoelaces.  The elastic gore has a substantial resiliency to pull the upper and side portions of the quarter back together as the foot contracts to maintain a secure fit.

Abstract: Methods are provided for separating polyhydroxyalkanoates ("PHAs") from plants, such as transgenic oil crop plants. The methods advantageously permit both the oil and the PHAs to be recovered from the plant biomass. To isolate the PHAs, in one embodiment, a biomass derived from an oil crop plant is pre-processed, for example by grinding, crushing or rolling. The oil then is extracted from the biomass with a first solvent in which the oil is soluble and in which the PHAs are not highly soluble to remove the oil. The biomass then can be extracted with a second solvent in which the PHA is soluble, to separate the PHA from the biomass. Alternatively, the PHA-containing biomass is treated with a chemical or biochemical agent, such as an enzyme, to chemically transform the PHA into a PHA derivative.  The PHA, derivative then is separated from the mixture using, for example, a physical separation process such as distillation, extraction or chromatography. Advantageously, using the method, the plant oils, the PHAs and PHA derivatives can be recovered and purified on a large scale from oil containing plants such as transgenic oil crop plants.
