International Classification:

G02B 6/00

US Classification:

25022714, 356 731, 356477, 385 12

Abstract:

An apparatus and method for determining a physical parameter affecting an optical sensor or a number of sensors in a network. The apparatus uses a narrow linewidth source at an emission wavelength λand an arrangement for varying the emission wavelength λof the radiation. An analysis module with curve fitting is used to generate a fit to the response signal obtained from the optical sensor. The physical parameter is determined form the fit rather than from the response signal. The apparatus can be employed with Bragg gratings, etalons, Fabry Perot elements or other optical sensors.

US Classification:

372 20, 372 14, 372 29022, 372102

Abstract:

Tunable external cavity lasers are used in applications such as interferometry, FM spectroscopy, and optical communications equipment testing. Mode hop free high bandwidth frequency modulation operation is desired in a tunable external cavity laser. This application describes new and novel techniques for controlling the output wavelength of a tunable external cavity laser while suppressing mode hop.

Assignee:

Bookham Technology PLC - Abington

International Classification:

H01S 3/115
H01S 3/10

US Classification:

372 12, 372 20

Abstract:

A laser-emitting device may be coupled to an electro-optically controlled wavelength actuator. An electro-optically controlled wavelength actuator may be a holographic wavelength actuator or a liquid crystal wavelength actuator. The electro-optically controlled wavelength actuator may function as a tunable diffraction grating for external cavity lasers.

International Classification:

A61F 2/06

US Classification:

623 112, 623 111, 623 123, 606108

Abstract:

Devices for loading a collapsible implant onto a delivery catheter. In one aspect, a loading device comprises an outer tubular structure and an inner tubular structure. The outer tubular structure comprises a narrowing passage configured to receive a catheter at one end and a collapsible implant at another end. The inner tubular structure is configured to move slidably and co-axially within the outer tubular structure. The inner tubular structure comprises a carrier pin configured to move within the narrowing passage as the inner tubular structure slides into the outer tubular structure. The sliding of the inner tubular structure into the outer tubular structure causes an implant mounted on the carrier pin to collapse as the implant moves through the narrowing passage and into the distal end of a catheter. In an optional aspect, the outer tubular structure further comprises a grasper to stabilize the catheter for receipt of the collapsible implant, and the internal diameter of the inner tubular structure varies to cause the grasper to first contract and stabilize the catheter, and then expand and release the catheter, as the grasper moves into the inner tubular structure.

International Classification:

A61B 18/18

US Classification:

606 51

Abstract:

A surgical device comprising a clevis defining a longitudinal axis and a jaw comprising a first member and a second member. A slider is slidably engaged to the clevis, the slider comprising a pin. The pin is receiveably engaged in the first slot and the jaw is selectively moveable between a first position and a second position through longitudinal movement of the slider. In various embodiments, the first and second members are movable between an angular open position, a parallel open position, and a parallel closed position.
