    摘要： A medical electrical lead is provided that is readily manufactured using a minimal number of parts, has a reduced size and improved reliability during implantation and extraction. The lead includes a modular electrode head assembly that is joined to a lead body at a butt joint. The butt joint is stabilized in at least four possible ways: insulation tubing that spans the joint is bonded to the electrode head assembly; two cabled conductors extending the length of the lead body are coupled to the electrode head assembly; an electrode head alignment peg interlocks with and is bonded to the lead body; and a coil electrode is positioned across the butt joint on the outer diameter of the assembly and the lead body. The lead size is minimized by using a compact retraction stop mechanism, a low-friction, press-fit drive shaft seal, and a small diameter coiled conductor insulated by a thin-walled insulating tube.

    摘要： An implantable cardioversion/defibrillation lead having an elongated insulative lead body carrying a tip electrode located at its distal end and a cardioversion/defibrillation electrode located on the lead body, proximal to the tip electrode. An elongated conductor coupled to the tip electrode extends proximally within the lead body. At the proximal end of the lead body is a first connector assembly carrying a first connector and a second connector assembly carrying a second connector. An elongated, stranded or cabled conductor is coupled to the cardioversion/defibrillation electrode and to the second connector and extends uninterrupted therebetween. A cylindrical transition member is coupled to the first connector by means of a coiled conductor. A press-fit sleeve having a longitudinal lumen extending therethrough compresses the stranded or conductor between the press-fit sleeve and the transition member to provide electrical interconnection between the stranded or cabled conductor and the transition member.

    摘要： A method and system for controlling the wavelength of light emitted by a tunable laser. The system includes a wavelength tuner that provides information of a desired wavelength; a coupler for tapping a portion of the light from the tunable laser; and an apparatus for measuring the actual wavelength of the light. The apparatus takes the portion of the light as an input signal and splits the input signal into two beams that are directed through two paths of different optical lengths. Then, the two beams are interfered with each other in order to form a fringe pattern at an observation plane, where the fringe pattern is detected and analyzed to determine the wavelength of the light. A processor compares the difference between the desired and determined wavelengths, and sends a tuning signal to the tunable laser forming a feedback control of the tunable laser.

    摘要： A single channel M×N optic switch is provided in accordance with the present invention to steer light radiating from any one fiber in an input bundle into any selected fiber in an output bundle. Precision beam-steering optics is implemented using a Risley prism pair controlled by a small computer. In order to efficiently couple light between two single-mode optical fibers a low-aberration lens approximately collimates the light from the source fiber before it is passed through the Risley prisms in order to minimize the aberrations introduced by the prisms as they collectively deflect the beam through some precise angle. A second low-aberration objective lens is used to refocus the light at the core of a selected output fiber. The focusing lens transforms the angular deflection of the beam into a change in the position of the focused spot in the focal plane of the lens. In order to switch the light beam from one fiber in the output bundle to another, the Risley prisms are individually rotated about the optical axis to predetemined orientations so as to deflect the collimated light at the exact angle necessary to direct the focused spot to the core of a selected output fiber.

    摘要： A read/write arm for use in an optical memory system. The read/write arm of the present invention has reflective surfaces for directing an optical beam from the arm rotation axis on to an optical disk. The arm features a lightweight lens mounted at one end of the arm for focusing a light beam onto an optical disk. The focal distance of the light beam may be adjusted using piezoelectric actuators mounted on the read/write arm for precisely deflecting the arm. The light beam may be further adjusted through use of a relay lens interposed between a collimating lens and the object lens. This arrangement is advantageously optimized through the use of feedback loops.

    摘要： Multiple element laser diode assembly incorporating a cylindrical microlens and at least one of an astigmatism correcting element and a collimating element. The use of a single purpose cylindrical microlens, for instance for circularizing a beam of laser light output from said diode, in operative combination with at least one additional optical element for correcting astigmatism and for collimating the beam enables the passive mounting of the several optical elements of the assembly without an active alignment step. The cylindrical microlens may incorporate as single powered surface, as may the astigmatism correction element. Alternatively, the astigmatism correction element may comprise a tilted optical plate. The collimating lens may be a spherical lens.
