Title: Optical pulse source for long haul optical communication systems
Inventor: WESTBROOK PAUL STEPHEN
IPC: H04B10/145
Filed: 2002-03-12
Granted: 2007-05-15
Abstract: In accordance with the invention, a modulated RZ pulse source comprises a modulated light source optically coupled to a stabilized Bragg grating filter and one or more optical taps. The light source is preferably modulated in power and frequency and has an adjustable channel wavelength .lambda. The Bragg grating filter has a reflectivity bandwidth having a high slope reflectivity cutoff and is preferably tunable. A  feedback arrangement responsive to the taps keeps the source channel wavelength .lambda. on the edge of the reflectivity bandwidth for shaping RZ pulses. When the Bragg grating is stabilized, the feedback system maintains .lambda. at a value linked to the grating reflectivity edge and, by overlapping at least part of the optical spectrum of the source, converts the modulated source light into RZ pulses with high extinction ratio (>= 12 dB). The result is a high power, jitter-free RZ pulse source that is compact, inexpensive and power efficient.

Abstract: A multi-bipolar configured electrode array and means to uniquely position said array within the scalae of the human cochlea is described. Said array is inserted into the scala tympani, scala vestibuli or both, by a surgeon. The electrode array may be pre-formed to lightly hug the modiolar wall of a scala so as to position the electrodes in close proximity to the cochlear spiral lamina and spiral ganglia in the modiolus. Mechanical features within said array allow the surgeon to further position said array against the modiolar wall of the scala, post insertion, and to mechanically retain such positioning of said array. Such positioning is in close proximity to surviving neural sites in the spiral lamina and/or spiral ganglion cells in the modiolus to efficiently stimulate functioning auditory neural elements. The multi-bipolar electrode configuration achieves a high degree of spatial selectivity, thus improving the implantee's speech percepts.

Title: Radiotherapy apparatus and collimator set therefor
Inventor: BROWN KEVIN JOHN
IPC: G21K1/04
Filed: 2001-09-19
Granted: 2008-11-25
Abstract: A collimator set for a radiotherapy apparatus comprises, in sequence, an aperture collimator, a multi-leaf collimator with a pair of opposing arrays of elongate leaves each moveable longitudinally in a Y direction, and a leaf ed ge collimator, the aperture collimator being adapted to collimate the beam in t he X and Y direction to a first extent, and the leaf edge collimator being adapted to further collimate the extent of the beam in the Y direction to a second and therefore lesser extend. This means that to close a pair of opposing leaves, they are moved to their minimum separation, with the gap being convered by the leaf edge collimator. The MLC is after the aperture collimator, so in combination with thin leaves, the MLC leaves will project a much reduced leaf width at the isocentre of the radiotherapy apparatus and collimation of the radiation field by fractional leaf widths becomes unnecessary. A radiotherapy apparatus comprising a collimator set as defined above is also disclosed.
