Abstract: A radio transmitting apparatus wherein unnecessary consumption of transmission power can be suppressed and PAPR (Peak to Average Power Ratio) can be reduced in multicarrier communication. In the apparatus, a repetition part (105) replicates (repeats) each symbol outputted from a modulating part (103) to generate and output a plurality of identical symbols to an S/P part (107), which converts the symbol sequence outputted in series from the repetition part (105) into parallel symbol sequences and outputs them to an interleaver (109). The interleaver (109) then reorders the symbol sequences outputted from the S/P part (107) and outputs them to a mapping part (111), which removes, in accordance with the propagation path quality of each of subcarriers constituting OFDM symbols that are multicarrier signals, some of the identical symbols as replicated by the repetition part (105) and then maps the rest of the symbols onto subcarriers for application to an IFFT part (113).

Abstract: A non-stereo fundus image is used to obtain a plurality of glaucoma indicators. Additionally, genome data for the subject is used to obtain genetic marker data relating to one or more genes and/or SNPs associated with glaucoma. The glaucoma indicators and genetic marker data are input into an adaptive model operative to generate an output indicative of a risk of glaucoma in the subject. In combination, the genetic indicators and genome data are more informative about the risk of glaucoma than either of the two in isolation. The adaptive model may be a two-stage model, having a first stage in which individual genetic indicators are combined with respective portions of the genome data by first adaptive model modules to form respective first outputs, and a second stage in which the first outputs are combined by a second adaptive mode. Texture analysis is performed on the fundus images to classify them based on their quality, and only images which are determined to meet a quality criterion are subjected to an analysis to determine if they exhibit glaucoma indicators. Also, the images are put into a standard format. The system may include estimating the position of the optic cup by combining results from multiple optic cup segmentation techniques. The system may include estimating the position of the optic disc by applying edge detection to the funds image, excluding edge points that are unlikely to be optic disc boundary points, and estimating the position of an optic disc by fitting an ellipse to the remaining edge points.

Abstract: A system for three-dimensional reconstruction of a surface profile of a surface of an object is provided that utilizes a binary pattern projected onto the surface of the object. A binary string consisting of a series of “1”s and “0”s is first created, and a binary pattern of light that is constructed in accordance with the binary string such that bright and dark bands of light of equal widths correspond to “1”s and “0”s from the binary string respectively is projected onto the surface. The binary pattern is shifted with respect to the surface multiple times, during which an image of the binary pattern illuminating the surface is obtained at each position of the binary pattern. Thereafter, a height of each predetermined point on the surface is calculated relative to a reference plane based upon the images cumulatively obtained at said predetermined point.

Abstract: An echo canceller is proposed that has an echo path change detector (10) capable of reliably distinguishing an echo path change from the condition of double talk. The echo path change detector is adapted to sample filter parameters from an FIR adaptive filter in the echo canceller, and to detect a change in intensity in a pattern formed by the sampled filter parameters. An echo path change is signalled when the degree of said pattern intensity change exceeds a predetermined level. The invention resides in the understanding that the parameters or coefficients of the adaptive FIR filter react differently to a condition of double talk or echo path change. Specifically, when these parameters are sampled and represented as an intensity pattern, a significant change in this intensity pattern over time can indicate an echo path change.

Abstract: A method and apparatus for estimating speech intelligibility in a mobile communications network component handling two-way communication between two ends of a signal path. Test signals adapted for speech intelligibility measurements are inserted into the signal path to simulate two-way communication. Double-talk is detected during the communication, and speech intelligibility measurements are performed only during periods of double-talk. This enables the effect of echo to be taken into account while avoiding undesirable effects from non-linear processing, and comfort noise if present, in the signal path. Voice enhancement devices may then be adjusted in response to the estimated speech intelligibility.
