摘要： This invention relates to a grip for a cricket bat handle. The grip may include a first raised portion for locating the top hand of a batter. The grip may also include a second raised portion for engaging with the palm of the bottom hand of the batter to prevent over gripping of the cricket bat handle by the batter. The grip may also include a third raised portion for engaging with the fleshy part of the bottom hand of the batter, between the thumb and index finger, in order to locate the bottom hand of the batter on the cricket bat handle. The grip may serve to correctly locate the hands of a batter on a cricket bat handle and/or the grip may assist or guide the hands of the batter during the playing of a batting stroke(s)

摘要： The present invention relates to a protective clip (10) that may be affixed to a motor vehicle steering linkage ball joint (7), and in particular to a clip that presents a heat shield (28) between a rubber sealing gaiter (11) surrounding the ball joint (7) and a brake disc (5), and that also covers over a slot (38) in a steering knuckle (4) above the joint (7). The protective clip 10 has a planar mid-section (24) with a hole (26) therethrough through which a ball mounting shaft (40) may pass. The heat shield (28) extends transversely away from a first edge (30) of the planar mid-section (24). A steering knuckle engaging feature (49) is proximate a second edge (32) of the planar mid-section (24) opposite the first edge (30), the engaging feature (49) being non-coplanar with the planar mid-section. A spring clip (34) extends from the second edge (32) and is concave towards the planar mid-section (24).

摘要： The percentage fraction of fundamental mode power located in the cladding holes of different holey fibers (PFholes) is shown as a function of wavelength in microns of the fundamental mode (&lgr;). Properties of two groups of holey fibers are shown. The upper group of three curves shows embodiments of the invention with &Lgr;=0.75 &mgr;m and d/&Lgr;=0.6, 0.7 & 0.8 respectively, where d is the hole diameter and &Lgr; the hole spacing or pitch. The lower group of curves, which are almost superimposed on each other, show properties of holey fibers representative of the prior art with &Lgr;=3.2 &mgr;m and d/&Lgr;=0.6, 0.7 & 0.8 respectively. A huge improvement in the mode power present in the holes is evident. In the prior art curves, the mode power fraction is generally less than 1%, whereas with the illustrated embodiments of the invention, holey fibers with 10-40% of the fundamental mode power in the holes are achieved. Generally the holey fiber should be structured such that the wavelength of the guided light &lgr;>2.2&Lgr;. For telecommunications wavelengths, this means that the hole spacing should be smaller than typical in the prior art, i.e. around 1 &mgr;m or less, and the hole diameter should be as large as possible in relation to the hole spacing, preferably d/&Lgr;>=0.6.

摘要： An optical device, suitable for use either as a coherent receiver or analog-to-digital converter, of optical phase modulated signals borne on a carrier. The signal is four-wave mixed with a pump to generate a non-linear comb of a series of harmonic components of the signal. The modulation-free carrier is also combined with the pump to generate an equivalent linear comb matched in frequency to the components of the non-linear comb. The harmonic and modulation-free components are linearly combined so they interfere in a pairwise manner, and then the interfered frequency components are separated out in an optical wavelength division demultiplexer into a plurality of frequency-specific optical output channels. A plurality of photodetectors connected to respective ones of the optical output channels then converts the analog values in each channel to respective electronic signals which are then digitized using a processor into binary digits using a thresholding process.

摘要： Apparatus for providing timing jitter tolerant optical modulation of a first signal by a second signal, the first signal having a first wavelength, the second signal including a plurality of second signal pulses having a second pulse shape and a second wavelength. The apparatus includes a first signal input port, a second signal input port, a coupler, a grating and a non-linear optical device. The apparatus is configured to direct the second signal at the second signal input port to the non-linear optical device via the coupler and the grating, and to direct the first signal at the first signal input port to the non-linear optical device. The grating is a superstructured fibre Bragg grating that converts the second signal pulses into intermediary pulses each having an intermediary pulse shape. The intermediary pulse shape is such that it provides a switching window within the non-linear optical device.

摘要： A source of optical pulses, comprises an optical source operable to generate ultrashort optical pulses at a first wavelength; and an optical fiber amplifier comprising an optical fiber having a core containing a dopant to provide optical gain at the first wavelength and anomalous dispersion over a wavelength range including the first wavelength and a second wavelength. The optical fiber receives the ultrashort optical pulses, amplifies the ultrashort optical pulses, and alters the wavelength of the ultrashort optical pulses to at least the second wavelength by the soliton-self-frequency shifting effect. Microstructured and/or tapered fibers can be used to provide the required dispersion characteristics. Pulses can be generated in one of three spectral regimes—monocolor solitons, multicolor solitons and continuous broadband spectra by adjusting the energy of the optical pulses, and tunability can be achieved by varying the power of pump light provided to the amplifier.

摘要： An optical regenerator for regenerating a multi-level phase encoded signal. A first non-linear medium (HNLF1) generates a comb of frequency harmonics from the signal under the action of a coherent pump, each component bearing the phase encoded data. A filter selects the first and (M−1)th order components. The filtered signal is then input to a second non-linear medium (HNLF2) where a further pump is applied, to coherently add the first and (M−1)th order components and regenerate the signal by reducing phase noise.

摘要： Optical code division multiple access (OCDMA) coder:decoder gratings have been fabricated. The modulated refractive index profile that makes up the OCDMA coder:decoder grating incorporates changes in polarity between OCDMA chips by discrete phase shifts, thereby to provide bipolar coding through phase modulation. (In another embodiment quadrupolar coding is achieved). For NRZ modulation, each grating section is either in phase with, or has a predetermined phase shift relative to, the preceding grating section, depending on whether the OCDMA signature has a change in polarity between chips. RZ modulation is also possible. Results are presented from specific examples of bipolar OCDMA with NRZ modulation, which show higher data rates (10 Gbit/s), shorter chip-lengths (6.4 ps) and far longer code sequences (63 bits) than previously demonstrated. Other embodiments relate to optical packet switching, for example using the Internet Protocol (IP) or Asynchronous Transfer Mode (ATM).
