The present invention is directed to a footwear construction having an insert of unitary structure and made of a single flexible material for providing increased structural support and strength of the footwear while maintaining flexibility of the footwear. Unlike the prior art insert, the present invention makes use of only a single material is used to manufacture the insert. A preferred material should be pliant or flexible and yet can provide the strength and structural support to the footwear in which the insert is used. Instead of using materials of different softness for the various sections in the insert to facilitate bending of the footwear, openings are added to various locations in the insert to facilitate planar bending movement. Such openings are commonly located in the forefoot section. To increase structural support and strength to the footwear, the insert is fixedly secured to the footwear.

An alignment system for co-aligning multiple laser beams to a single spatial reference point in real time. The alignment system includes a beam sampler for sampling the multiple pulsed laser beams. The sampled laser beams are directed onto a quadrant photo detector or quad cell. The output signals from the quad cell are directed to a detector signal integration circuit which develops error signals for driving tip-tilt mirrors in the beam path of the multiple lasers. The system includes a gate, reset and pulse ID generator for generating pulse trigger signals for each of the multiple lasers and signals for correlating the detector signals with the laser that produced the signal. Accordingly, a system is provided for a time multiplexed, multiple laser system which automatically co-aligns the output beams from each of the lasers to a single spatial reference point in real time.

A method is provided for seeding laser system () for single longitudinal mode oscillation. The method includes coupling laser system () to be seeded for single mode output to a seed laser radiation source (). Next, the frequency capture range () and spacing () of the axial modes () of the cavity () of the laser system () are determined. A seed spectrum () is then generated from the seed laser radiation source () with a bandwidth () corresponding to the axial mode spacing (). The seed spectrum () includes a comb of discrete frequency components () with one or more of the discrete frequency components () being within the frequency capture range () of at least one of the axial modes (). The seed spectrum () is then injected into the cavity () such that at least one of the axial modes () oscillates with the seed radiation.

A deformable membrane mirror and a related method for its use, the mirror including a deformable membrane having a reflective front face and a back face, and further including electrodes located on both sides of the membrane, to provide a desired surface contour without imparting a concave bias to the membrane. The electrodes include a first set of electrodes spaced from the back face of the membrane, and at least one additional electrode spaced from the front face of the membrane.

An optical channel waveguide having a reflection grating and a related method for its fabrication. The grating is apodized to provide a desired reflection or transmission spectral characteristic, by varying the grating width along the length of the grating in the direction of light propagation. The grating has multiple parallel elements extending across the waveguide channel width, and apodization is effected by appropriate selection of the width of each element relative to the width of the channel, without varying the grating duty cycle or other parameters.

A hybrid outsole construction comprises high-density carbon rubber molded to low-density blown rubber, providing increased flexibility, cushion, and comfort while maintaining durability, traction, and shock absorbency of the footwear. In accordance with another aspect of the present invention, the hybrid outsole construction is stitched to the upper layers of the footwear, for example using a welt.

A footwear having an outsole coupled to an upper by a preformed closed-loop welt. The welt is a formed ring-shaped structure having no ends or breaks. The welt is sized and shaped to receive the upper-outsole junction. The welt provides an intermediary structure for coupling the outsole to the upper. The welt includes a sidewall that facilitates stitching and gluing an upper portion of the sidewall to the upper.

A technique for compensating for the effects of thermo-optic distortions in a solid state laser gain medium, and reducing optical path differences in the laser. A diode array coupled to the laser gain medium is selectively modulated to provide pump power, the intensity of which varies across the aperture of the gain medium. The modulated diode array has a spatial power profile that is selected to compensate for thermal distortions arising from various causes. The modulated diode array may be one of several diode arrays providing pump power to the laser gain medium, or may be an auxiliary diode array with the sole purpose of providing compensating power input with a selected profile across the aperture of the gain medium.
