  • Patent number: 9074936
    Abstract: Methods and apparatus are disclosed, and include: (a) separating an input electromagnetic waveform into a plurality of intermediate waveforms, each of the intermediate waveforms being spatially separated from one another; (b) dispersing frequency components of each intermediate waveform onto different regions of a spatial light modulator and modulating at least some of the dispersed frequency components with the spatial light modulator; and (c) recombining the dispersed frequency components for each of the intermediate waveforms to produce a plurality of temporally shaped output waveforms.

  • Patent number: 9000376
    Abstract: An apparatus for detecting electromagnetic radiation within a target frequency range is provided. The apparatus includes a substrate and one or more resonator structures disposed on the substrate. The substrate can be a dielectric or semiconductor material. Each of the one or more resonator structures has at least one dimension that is less than the wavelength of target electromagnetic radiation within the target frequency range, and each of the resonator structures includes at least two conductive structures separated by a spacing. Charge carriers are induced in the substrate near the spacing when the resonator structures are exposed to the target electromagnetic radiation. A measure of the change in conductivity of the substrate due to the induced charge carriers provides an indication of the presence of the target electromagnetic radiation.

  • Publication number: 20140174760
    Abstract: A technique facilitates conveyance of equipment along a wellbore or other tubular structure. A tractor is provided with a plurality of wheels oriented to engage a surrounding wall. Rotation of the wheels drives the tractor and causes longitudinal movement of the tractor with respect to the surrounding wall via a tangential force created between each wheel and the surrounding wall. Each wheel comprises teeth having a wheel tooth geometry which enhances cooperation with the surrounding wall. For example, the wheel tooth geometry may be designed to cooperate with the tangential force to push debris out of the teeth of each wheel during rotation of the wheel along the surrounding wall. In some applications, the wheel tooth geometry is designed to present a plurality of raised, rounded surfaces which engage the surrounding wall with a low stress impact.
