Abstract: An article of footwear with a heel region including a posterior end of the article of footwear, a mid-foot region, and a forefoot region including an anterior end of the article of footwear; a lateral side, and a medial side opposite the lateral side; an upper; and a sole structure coupled to the upper. The sole structure has a midsole with a first cushioning element extending from the posterior end to the anterior end; a second cushioning element extending from the mid-foot region to the posterior end, the second cushioning element being formed of a different material than the first cushioning element; and a shell with a plurality of circumferentially-spaced apart protrusions, wherein each of the plurality of protrusions is directly coupled to the second cushioning element.

Abstract: A stacking bracket with locking tabs for easily, economically, and securely attaching and horizontal shelving to an upright shelving support post rack assembly as well as connecting and stacking such rack assemblies vertically together, the system and component parts being adaptable and configurable such that shelves, drawers, and other rack accessory elements may be readily incorporated into the system, assembly, and methods for use of same.

Abstract: According to one aspect, a sparse optical system is provided. The sparse optical system includes optical segments, an optical source module to generate beams of light, a collimating module to direct the beams of light towards two adjacent optical segments, a detector to receive a reflection of the beams of light from the optical segments, and a processor. The processor instructs the optical source module to generate a first beam of light, determines a first measurement of an alignment of the two adjacent segments based on the reflection of the first beam, adjusts a position of an optical segment based on the first measurement, instructs the optical source module to generate a second beam of light, and determines a second measurement of the alignment of the two segments based on the reflection of the second beam.

Abstract: A multimode radiation source is disclosed. One embodiment includes a waveguide radiator and an orthomode transducer coupled to the waveguide radiator to provide a first signal to the waveguide radiator. The waveguide radiator is configured to receive the first signal and to radiate the first signal at a first location as a first spherical wave signal with a first phase center. The multimode source also includes transmission medium coupled to the waveguide radiator and configured to radiate a second signal and a third signal from the first location as a second spherical wave and a third spherical wave with substantially the first phase center.
