  • Publication number: 20150086214
    Abstract: A tuning device for a pluggable XFP and SFP+ and DWDM transceiver devices. Also provided are applications for CWDM XFP, and SFP+ and future form factors as well as DWDM and CWDM SFP. This tuning device is for use with tunable DWDM and CWDM transceivers, and provides the ability to lock the tune of the transceiver to prevent a host device from automatically retuning the transceiver.

  • Patent number: 8504304
    Abstract: A method of enhancing the throughput and applicability of NMR-based structure determination of protein-ligand complexes is disclosed. The method circumvents the need for protein sequence-specific resonance assignments and combines NMR data analysis and ligand docking methods into an integrated process. In one embodiment, NMR data is used to filter docking results to identify the most consistent binding modes, thereby providing structural information in a high-throughput fashion without the need for assigning protein resonances. Trial assignments for protein-ligand nuclear Overhauser effect (NOE) interactions are also produced by the method.

  • Publication number: 20100048397
    Abstract: Embodiments herein provide the formulation and use of gamma-aminobutyric acid (“GABA”) in combination with one or more of a herbicide and an insecticide. In one embodiment, the herbicide is glyphosate; in another, the insecticide is imidacloprid. Methods and formulations described and claimed herein may be useful for encouraging growth of desired plants while discouraging the growth of undesirable plants and/or pests. Method and formulations described and claimed herein may be useful for alleviating stress conditions for desirable plants, and for decreasing yield losses resulting from application of herbicides and/or insecticides.

  • Publication number: 20080207448
    Abstract: Seed coatings and coated seeds as provided herein include at least one fungicide and at least one VAM fungus-enhancing composition. Coated seeds exhibit enhanced growth due to depression or elimination of undesirable fungi coupled with either enhanced growth of VAM fungus or lack of detrimental fungicide effect on VAM fungus.

  • Patent number: 7252407
    Abstract: Lighting apparatus is provided comprising a light source (10), the light source being encapsulated in a protective medium (11) to seal the light source against ingress of moisture, the lighting apparatus having a heat sink (12, 13), the heat sink having a first region (12) in communication with light source (10) to receive heat from the light source (10) and a second region (13) which projects externally of the protective medium, such that the heat sink can dissipate heat to the ambient area. The invention provides light apparatus which is particularly suitable for use with caving lamps, although other uses are possible, for example in traffic lights or the lights of a motor vehicle, where the encapsulation would provide protection against rain.

  • Publication number: 20070108383
    Abstract: A device for detecting infrared radiation is described that comprises a resonator element (36; 72; 96; 120) fixably attached to a supporting frame (32;130). The supporting frame (32;130) is arranged to absorb infrared radiation received by the device. The resonator element (36; 72; 96; 120) has a resonant property, such as resonant frequency, that varies with temperature. The device may comprise a plurality of detection elements (70), each detection element comprising a resonator element (72) fixably attached to a supporting frame. A thermal detector array device may also be provided.

  • Publication number: 20070029092
    Abstract: In systems and methods for production of hydrocarbons fluids from a formation surrounding a wellbore, a production assembly is cemented into place, and excess cement is then cleaned from the production tubing and liner. Thereafter, hydrocarbon fluids are produced and artificial gas lift assistance is provided. All of this may be accomplished in a single trip (mono-trip) of the production tubing.

  • Publication number: 20060237191
    Abstract: Devices and methods for methods for cleaning of excess cement from a production assembly as well as from the annulus surrounding the production assembly. A hydrostatic closed circulation valve (HCCV) assembly is described that is primarily actuatable between open and closed positions by varying hydraulic pressure in the flowbore of the production assembly. The valve assembly is useful for selectively circulating working fluid into the annulus from the flowbore of the production assembly.

  • Publication number: 20060215147
    Abstract: A retro-reflective identification tag capable of modulating an optical signal whereby to support bi-directional communication with an associated remote optical interrogation device. The tag comprises a MOEMS modulating layer over a retro-reflective substrate, giving the tag a wide angle of effective operation. The tag modulator may optionally be switched on only responsive to detection of a precursor beam from the interrogation system in order to save power. The interrogation device may make use of multiple optical wavelengths for communicating with the tag.
