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.

To detect whether a closed-loop's voltage is out of range, a voltage detector includes first and second transistors that deliver first and second currents respectively to first and second high impedance nodes. The voltage detector further includes third and fourth transistors that draw third and fourth currents respectively from the first and second nodes. The first and second currents are scaled replicas of a current flowing through a current source of a voltage-to-current converter that converts the close-loop's voltage to a current and supplies a first voltage to the first and second transistors. The third and fourth currents are scaled replicas of a different current flowing through a current mirror of the voltage-to-current converter and that supplies a second voltage to the third and fourth transistors.

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 charge pump is configured to control current flow at an output node in response to input signals. A plurality of control signals are generated based upon the input signals. The control signals operate to control the timing and duration of current flows within the charge pump and to thereby reduce charge pump power consumption. Based upon the control signals, the conductivity of a first path between a power supply and the output node and a second path between the output node and a ground potential is varied. Optionally, the charge pump is disposed as part of a phase-locked loop (PLL), the input signals are produced by a phase/frequency detector, and current flow at the output node controls an oscillator element.

A workflow for 3D content authoring, delivery, and rendering is facilitated based on pre-authored image projections to obtain improvements in authoring efficiency. Additionally, a content delivery platform centered on such pre-authored image projections provides a mechanism for significantly improving streaming efficiency for 3D worlds. Multiple images encode primary surface detail of 3D worlds in real-time applications. Examples of such projections include images that can be as rich as film frames, feature animation frames, high end digital renders, concept paintings, or any suitable combination thereof. An algorithm for improved image projection camera path trajectories, sampling selection, and blending may be implemented by various systems and methods to facilitate smooth transitions during movements of a player within a game set in the 3D space. In addition, a back-projection technique may be implemented by various systems and methods to propagate revisions of one or more projections.
