摘要： A photometric device for investigating a sample, comprises an array of radiation sources that are spaced apart from one another, and which are operable to generate radiation that differs from that generated by the other radiation sources in the array. The device includes a lens arrangement for focusing the radiation at a region of space where a sample may be located for example by means of a sample holder, and at least one detector for receiving radiation from the region of space. Preferably, a number of detectors are employed that are spaced apart from one another, and especially about an axis of the device, so that one radiation detector can detect radiation transmitted by the sample and the other detectors can detect radiation scattered by it. The radiation sources may be time division multiplexed so that in each time slot the detectors receive radiation originating from each radiation source. In an alternative embodiment, the radiation from the region of space may be transmitted to the sample via a beam homogeniser, for example an optical waveguide in the form of an optical fibre, which may be used to reduce or remove speckle where laser diodes are employed as the radiation sources. The device may be used to determine the particle size distribution of particles in a sample by a method employing Bayesian inference.

摘要： The invention comprises an encoder for encoding a stegotext and a decoder for decoding the encoded stegotext, the stegotext being generated by modulating the log power spectrogram of a covertext signal with at least one key, the or each key having been added or subtracted in the log domain to the covertext power spectrogram in accordance with the data of the watermark code with which the stegotext was generated, and the modulated power spectrogram having been returned into the original domain of the covertext. The decoder carries out Fast Fourier Transformation and rectangular polar conversion of the stegotext signal so as to transform the stegotext signal into the log power spectrogram domain; subtracts in the log power domain positive and negative multiples of the key or keys from blocks of the log power spectrogram and evaluates the probability of the results of such substractions representing an unmodified block of covertext in accordance with a predetermined statistical model.

摘要： A barcode reader (100) and processing circuitry (18) are disclosed for identifying a position of a cylinder rod (10), for example, along a path of movement. The barcode is marked on a surface (11) of the rod (10) and constitutes a series of markings (12) extending along a portion of the length of the rod (10). The markings (12) represent encoded information based on numbers calculated with a random number generator, and are grouped into subsets, each of which corresponds to a particular rod position. A portion of the rod (10) including a subset of barcode markings (12) is exposed to light emitted from the reader. Light reflected off the barcode is sensed with an array of photosensors (908) provided in the reader. The photosensors (908) generate electrical signals, and using Bayesian probability, a likely subset of markings is determined corresponding to the received electrical signals. Once identified, the markings subset is associated with a location corresponding to the position of the rod. A barcode reader (100) is also described that is relatively easy to assemble and provides uniform illumination of the barcode.

摘要： The present invention provides a public key cryptosystem which comprises an encryption device, said device having means for encrypting information including a feed-back loop which evaluates a one-way or a one-way trap door function incorporating modular exponentiation with a small positive exponent and thereby processes successively the blocks into which the information has been divided, to encrypt the information; and a compatible decryption device. The encryption and decryption devices of the present invention provide an outstandingly high rate of encryption and decryption without impairing the level of security associated with public key cryptosystems.
