摘要： A harness for use with breathing apparatus has: a flexible hip plate 12 and a flexible bandolier-style shoulder panel 14, linked together by a strap 15, and a waist belt 16 fastenable by a sprung fastener. In use, the flexible hip plate 12 rests against the hip of a user (the left hip in this example), the waist belt is fitted around the waist of the user, and the shoulder panel 14 rests against the shoulder opposite to the hip against which the flexible plate is resting (the right shoulder in this example). At least the bandolier-style panel 14, and optionally also the hip plate 12 of the harness 10, are made of a resilient material which, though flexible, allows the harness substantially to retain its operational configuration even when not being worn.

摘要： A hose dispenser has a rotatable reel 10, holding a coiled hose 12 suitable for conveying breathable gas, mounted on a tubular steel frame 14. The reel has a pivoting arm 16, which has a portion defining an aperture, or “eye” 18 fitted thereon. The hose is threaded through the eye 16 so that the free end of the hose protrudes through the eye. The free end of the hose is fitted with a resilient frusto-conical protective hood 20. The hood provides two functions. First, it enables the free end of the hose to engage the eye of the arm 16, and secondly, it protects a valve 22, located on the free end of the hose, from damage. Another valve 24 is provided in the centre of the reel, which is connected to the other end of the hose. In use, the free end of the hose is carried by an operative, or is attached to breathing apparatus worn by the operative, and the other end is connected to a source containing gas for breathing. The arm 16 is mounted pivotally on the reel. Due to the fact that the hose is threaded through the aperture portion mounted on the arm, when the hose is put under tension, i.e. when the end of the hose is pulled so as to uncoil the hose, the arm lifts. If the hose becomes slack, i.e. when it is not being pulled, the arm falls under gravity. The pivoting arm 16 is operatively connected to braking means which provides a brake for the reel 10 holding the hose. When the brake is engaged rotational motion of the reel is inhibited, thus preventing undesirably large amounts of hose from being dispensed from the reel 10 when the hose is slack.

摘要： The invention provides time-synchronised transmission of data on the (polarisation or phase-modulated) QKD channel and the (on-off modulated) conventional channel such that a QKD bit is only transmitted when a zero, or sequence of zeros, is transmitted on the conventional channel. Also, there is co-directional propagation of the QKD and conventional channel. Further, there is dispersion management through wavelength selection or control of fibre properties or other means such that the “walk-off in time of the QKD pulses and the Raman pulses generated by the ones on the conventional channel is less than or of the order of one bit period. The latter can be achieved, for example, by placing the conventional and QKD channel wavelengths close to the point where the group velocity-induced time delay for optical pulses propagating in the fibre reaches a minimum. This dispersion minimum occurs at a wavelength of 1.3 microns in standard fibre. The invention discloses a receiver embodiment to implement the invention.

摘要： A suitable cross-linkable matrix precursor and a poragen can be treated to form a porous cross-linked matrix having a Tg of greater than 300° C. The porous matrix material has a lower dielectric constant than the corresponding non-porous matrix material, making the porous matrix material particularly attractive for a variety of electronic applications including integrated circuits, multichip modules, and flat panel display devices.

摘要： The invention provides a linear burst mode receiver comprising a first amplifier connected to a photodiode adapted to detect an optical input burst signal, a second amplifier connected to said photodiode; and means for deriving the peak input current of the detected burst signal using said second amplifier. The invention further provides means for using the derived peak input current to adjust the gain of the first amplifier during the preamble of each burst, such that the output voltage swing of the first amplifier equals a given reference, independent of the strength of the optical input burst signal. The usage of the fast feed-forward automatic gain control mechanism solves the problems with gain switching and non-linearity prevalent in today's burst-mode receivers.

摘要： A face mask (10) mechanically coupled to a lung demand valve (LDV) (12). The face mask (10) comprises a main mask and an inner mask (15) which fits over the wearer's mouth and nose. The interior of the inner mask (15) is in fluidic communication with the interior of the main mask (10) by means of non-return valves (16). The interior of the main mask is in fluidic communication with an inlet port (18) which is mechanically and fluidically coupled to a supply port (20) of an LDV. The LDV (12) includes a diaphragm and a cover (44) which comprises three parts (44a, 44b) and (44c). Exhaled air is used to flush the space around the diaphragm. Thus, any toxic or undesirable gas in the vicinity of the diaphragm is pushed out to atmosphere by the exhaled air flowing past and around the diaphragm.
