摘要： Apparatus for dispensing a predetermined volume of a liquid (18) comprises a reservoir (12) for the liquid, a channel (13) provided with an outlet (16) for conveying the liquid (18) from the reservoir to the outlet, and means for generating a pulse of gas. The apparatus is arranged such that the flow of gas causes a predetermined volume of liquid to be ejected from the outlet. The outlet comprises a pair of openings in the channel which face one another, the liquid being retained between the openings by surface tension in the absence of a flow of gas. The gas flow is directed towards one of said openings in use. The apparatus may be used to dispense volumes of a liquid reagent in the range 1 nl to 2νl. The apparatus avoids contamination of the liquid, and dispensing head construction allows devices to be low cost disposable units. The apparatus is less sensitive to liquid viscosity than existing devices.

摘要： A method of generating a second decorrelated audio signal from a first audio signal, for use in synthesising a 3D sound field, includes: a) deriving from the first signal a first delayed signal; b) multiplying this first delayed signal by a gain factor between zero and minus one to give a first delayed gain-adjusted signal; c) deriving from the first audio signal a second delayed signal, having a different delay time from the first delayed signal; d) multiplying this second delayed signal by a gain factor between zero and plus one (such that the said gain factors sum to zero) to give a second delayed gain-adjusted signal; e) combining said first and said second delayed gain-adjusted signals with the first audio signal to provide a second decorrelated audio signal. The first and second delayed signals are delayed by time periods which change in a substantially random manner.

摘要： A laminated artificial pinna having a concha, fossa and auditory canal. The auditory canal (23) is constructed and arranged relative to the concha (12), so that the distance (A) (see figure 7) from the centre of the entrance of the auditory canal (23) to the rear wall of the concha (12) lies within the range of 15 mm to 20 mm, the distance (B) (see figure 8) from the centre of the entrance of the auditory canal to the concha floor lies within the range of 9 mm to 15 mm, and the alignment of the turning point (C) (see figure 9) with the centre of the entrance of the auditory canal (23) is substantially horizontal. The pinna is made with the help of an encapsulated model of a human pinna. A cross-sectional shape is revealed by incrementally machining the encapsulated model away and of each revealed cross-sectional shape an image is taken. The image is used to produce a replica of the cross section out of sheets of material which are assembled in a stack to form the laminated model of the pinna.

摘要： The invention relates to an apparatus and method for chemical analysis. In a preferred embodiment the invention comprises a disc shaped member (1) which has a chamber (8), pathways (10a and b), reservoir (12) and analysis cells (16) formed integrally therewithin. A blood sample is introduced into the apparatus and is centrifuged so as to separate blood cells from serum. Serum is then subjected to a number of processes and/or tests, for example, in order to establish the state of the serum. The invention overcomes problems of prior art systems by being able to repeat certain processes, for example cyclical tests or reactions, by causing or permitting a sample to flow into a region or volume then allowing it to flow out, then allowing it to flow into the region or volume again. Thus washing or rinsing is possible. Optionally sealed pistons (32) which are housed in the disc (1) contain liquid reagents or solvents or water. A matrix of beads (26) whose surface has been coated with a reagent may be disposed in a reaction chamber.

摘要： In order to increase the size of the region (sweet-spot) in which a listener can experience an optimum binaural effect, thereby permitting the listener to move his head while listening, the signal attenuations introduced by left and right binaural channels (2L, 2R) are ajdusted in relation to the signal attenuations introduced by left and right crossfeed channels (22L, 22R), for example by adjusting the transfer function of crossfeed filters (24L, 24R) so that there is a significant amount of crosstalk signal remaining in the sweet-spot.
