Abstract: The invention relates to a computer-implemented Bayesian inference method for performing Bayesian inference in a Bayesian network, which includes a continuous child node (3) and its discrete parent node (2) having two states. Being provided with a calibrated continuous probability distribution of the observations of the child node (3) for each of the two states of the parent node (2), the inferring for a new observation of the child node (3) for which the state of the parent node (2) is not known of the probability of at least a first state of the parent node (2) makes use of masses of portions of the probability distributions that depend on a locational relationship of the probability distributions and the value of the new observation. This may ensure that the inferred probability of the first state of the parent node (2) monotonically changes with monotonically changing values of the new observation.

The public-key encryption device is configured to compute a second public-key matrix (u), the second public-key matrix (u) having fewer matrix elements than the first public-key matrix (b) of the private-key decryption device. This reduces computation and bandwidth requirements at the side of the public-key encryption device.

Abstract: A drinks machine has an output nozzle for delivering hot water or steam, Steam is used by a milk frothing unit whereas hot water is delivered by the output nozzle directly to the exterior of the drinks machine for collection in a drinks vessel. A single nozzle is thus provided for steam or hot water delivery and there is no need for any accessory when delivering hot water. This means that there is reduced cost, fewer components to lose, and simplified cleaning, in that only per-use cleaning of the milk frothing unit is required, not the fixed parts of the appliance associated with the milk frothing unit.

The gearless longitudinal translation device includes: a first friction wheel having at least a first beveled side surface, and a second friction wheel having at least a second beveled surface; a first linear rod disposed between the first and second friction wheels and in contact with the first and second beveled surfaces; and a control mechanism attached to the first and second friction wheels for rotating the first and second friction wheels.

Abstract: An ultrasound imaging system has an improved dynamic range control which enables a user to reduce image haze with substantially no effect on bright tissue in the image and without increasing speckle variance. A dynamic range processor processes an input image to produce an approximation image which is a spatially low pass filtered version of the input image. The dynamic range of the approximation image is compressed, and image detail, unaffected by the compression, is added back to produce a dynamically compressed image for display.
