Abstract: Methods and devices related to an improved mussel sock. The improved mussel sock is a mesh of cells constructed from strands of a first material such as polypropylene. Strands of a second material, with weaker mechanical properties than the first material such as cotton, are woven through the mesh so as to divide each cell into at least two sub cells. Once the mussel sock is full of mussels and after prolonged exposure to water, the second material will degrade and eventually give way to the mussel, thereby providing a mussel suck with a larger cell size. The improved mussel sock also has reinforced sides and are cut to predetermined lengths. One end of the predetermined length mussel socks are reinforcedly sewn shut to provide a ready to-use sock for the mussel farmer.

Title: Transmitting stage
Inventor: JAFARI HOUMAN
IPC: H04B1/04
Filed: 2003-11-10
Granted: 2011-04-05
Abstract: A transmission stage in polar loop technology includes an amplitude regulation means (16), a phase regulation means (17), a VCO (14) and a feedback path (19). In the feedback path a variable amplifier (19b) is provided. The amplitude regulation means (16) is further implemented in order to be controlled by a control means (22) according to a request for a power variation in the output signal of the amplifier in order to correspondingly vary an amplitude control signal for the power amplifier (13). Simultaneously, the control means (22) is implemented in order to correspondingly control the variable feedback path amplifier, so that the amplitude of the output signal of the variable feedback path amplifier remains in a narrowly limited predetermined range. Thus, power variations in the output signal of the amplifier operated in the non-linear area are held remote from the phase locked loop, so that the phase regulation means may be implemented at low cost and operates reliably anyway.

Abstract: A surgical instrument particularly suited to endoscopic use articulates an end effector by including an articulation mechanism in an elongate shaft that incorporates an electrically actuated polymer (EAP) articulation locking mechanism actuator. Thereby, additional options for articulation become feasible, especially those that are actively powered and would otherwise dissipate heat and power if required to maintain position. Alternatively, a mechanically actuated articulation mechanism may be designed with reduced strength, and thus size, since the EAP articulation lock mechanism assists in preventing back driving after articulation. Versions of a. EAP articulation locking mechanism lock a pivoting articulation joint and others lock a flexible neck articulation joint.

Abstract: Method simulating local prestack depth seismic migrated images from target models, without using either real or synthetic recorded data. The input is a background model and some surveys, with the possibility of defining some acquisition surfaces to describe any acquisition geometry of potential surveys. In addition, detailed target models are given, generated from different type of input, such as parameter grids, interpreted time- or depth-horizons with attributes, reservoir models, and other models .In the most efficient application of the invention, a point in the background model is chosen by the user and will act as a node for Green's functions calculation between the surveys/acquisition surfaces and that point. Green's functions can be calculated in many ways (classic ray tracing, Wavefront Construction, and Eikonal solvers are possible methods), the mandatory information being slowness vectors to form a sum vector called the scattering wavenumber.  According to some survey choices, the scattering wavenumbers are extracted, with various sub-selections, sorting, re-ordering, and used to create filters in the scattering wavenumber domain. Amplitudes, pulses, scattering pattern, Fresnel-zone effects, and other effects can be included in the filters. The latter are then applied to each target model to give a simulated prestack local image in depth after some transformation, like Fast Fourier Transform, from the wavenumber domain to the space domain. For better accuracy, local images for neighboring Green's functions nodes can be merged to form a classic prestack depth migrated section. A variant of the present invention is to simulate seismic traces in the time domain. The inner core of the invention, with application of scattering wavenumbers to build filters to apply to target models, can be applied in other domains, such as Ground Penetrating Radar, and possibly acoustical and medical imaging.

Title: Method and apparatus for applying dynamic loads to a locked gear train for testing power transmission components
Inventor: BECKMAN KENNETH O
IPC: G01M13/02
Filed: 2004-11-09
Granted: 2009-03-17
Abstract: An apparatus for testing power transmission components of a locked gear train having two helical gears coupled on a first shaft meshed with two helical pinions coupled on a second shaft, with the two gears arranged to axially translate (while rotating) with respect to the two pinions when a linear force is applied to a thrust bearing at an end of the first shaft. The axial displacement of the two gears causes torsional displacements of the meshed gear and shaft elements, creating a dynamic torque within the locked train assembly. Under rotation, this dynamic torque subjects the components within the locked gear train to a much higher power level for testing.

Title: Apparatus and methods for distributed temperature sensing
Inventor: HARTOG ARTHUR H
IPC: G01K11/32
Filed: 2004-10-18
Granted: 2011-07-12
Abstract: A sensing fibre for use in a distributed temperature sensing system comprises an optical fibre to be deployed in a measurement region in which a temperature measurement is to be made, which incorporates a reflective element, such as a join between portions of fibre, and a coiled fibre portion positioned adjacent a distal side of the reflective element, the coiled fibre portion contributing substantially nothing to the spatial extent of the optical fibre when deployed. In use, the effect of any forward propagating light incident on the reflective element that is returned for detection by the system, and which saturates the detector, can be eliminated by removing the part of the detected signal that corresponds to the coiled portion, after which the detector will have recovered. The remaining parts of the signal can be used to derive the distributed temperature profile since these parts represent the whole extent of the sensing fibre owing to the lack of spatial extent of the coil. Coils can be provided on both sides of the reflective element for double-ended temperature sensing techniques.
