Patent CA-2352731-C (CA)
Title: Optical characteristic measuring apparatus, the method thereof and recording medium
Inventor: YAMASHITA TOMOYU
IPC: G01M11/02
Filed: 2001-07-09
Granted: 2005-07-26
Abstract: The object of the present invention is to provide an apparatus that can perform measurement of chromatic dispersion, even if the wavelength of variable-wavelength light source and that of fixed-wavelength light source for reference are identical with each other.      The variable-wavelength light generated by a variable-wavelength light source 12 is subjected to intensity modulation to a frequency f by a first optical modulator 15a and transmitted from one end 30a to the other end 30b of an optical fiber 30. The fixed-wavelength light generated by a fixed-wavelength light source 14 is subjected to intensity modulation to a frequency f by a second optical modulator 15b and transmitted from the other end 30b to the one end 30a of optical fiber 30. Therefore, it is possible to separately obtain the variable-wavelength light and fixed-wavelength light transmitted through the optical fiber 30 using a second directional coupler 28 and a first directional coupler 26, respectively, regardless of wavelengths thereof. Accordingly, it is also possible to perform the comparison of phase and measurement of chromatic dispersion, even if the wavelengths of variable-wavelength light source and fixed-wavelength light source for reference are identical with each other.

Granted: 2007-02-27
Abstract: Methods and apparatus for shaping pipes, tubes, liners, or casing at downhole locations in wells. Use is made of rollers bearing radially outwards against the inside wall of the pipe (etc.), the rollers being rolled around the pipe to cause outward plastic deformation which expands and shapes the pipe to a desired profile. Where one pipe is inside another, the two pipes can be joined without separate components (except optional seals). Landing nipples and liner hangers can be formed in situ. Valves can be deployed to a selected downhole location and there sealed to the casing or liner without separate packers.  Casing can be deployed downhole in reduced-diameter lengths and then expanded to cast a well without requiring larger diameter bores and casing further uphole. The invention enables simplified downhole working, and enables a well to be drilled and produced with the minimum downhole bore throughout its depth, obviating the need for large bores. When expanding lengths of casing, the casing does not need to be anchored or made pressure-tight. The profiling/expansion tools of the invention can be deployed downhole on coiled tubing, and operated without high tensile loads on the coiled tubing.

Title: Combination dissector and expander
Inventor: YOUNG RODERICK A
IPC: A61F2/12
Filed: 1997-06-30
Granted: 2007-08-21
Abstract: A combination tissue dissector and long term expander is disclosed for use in plastic surgery applications and other applications where it is desirable to dissect a tissue pocket, and serially expand the dissected pocket through long term tissue expansion. The combination device performs the separate functions of dissection, and long term expansion in a single balloon package. In an exemplary embodiment, three sheets of substantially inelastic material (45, 47, 48) are bonded together at their outer margins to form two discrete inflatable chambers (49, 51). The lower inflatable chamber (49) defined by the middle and lower balloon sheets (45, 47) is further welded together at various points (50) over the sheet's surface area to create a semi-rigid base portion (44) which provides a fiat well-defined footprint for the balloon. The semi-rigid base portion (44) prevents further enlargement of the tissue pocket at the margins when the device (32) is utilized as a tissue expander. In a preferred method of use for the combination device, the combination device is tunneled bluntly to a desired location within the body. The device (32) is then inflated to dissect tissue layers along natural tissue planes and create a tissue pocket. After dissection, the combination device may be left within the body as a temporary implant to further expand the tissue pocket through long term expansion until the desired tissue pocket volume is achieved.
