Method for analyzing ocular and / or head orientation characteristics of a subject. A detection and quantification of the position of a driver's head and / or eye movements are made relative to the environment. Tests of the data are made, and from the data, locations of experienced areas / objects-of-subject-interest are deduced. When a driver of a vehicle is the subject, these areas / objects-of-driver-interest may be inside or outside the vehicle, and may be constituted by (1) “things” such as audio controls, speedometers and other gauges, and (2) areas or positions such as “road ahead” and lane-change clearance space in adjacent lanes. In order to “standardize” the tracking data with respect to the vehicle of interest, the quantification of the position of the driver's head is normalized to the reference-base position thereby enabling deducement of location(s) where the driver has shown an interest based on sensed information regarding either, or both of (1) driver ocular orientation or (2) driver head orientation.

Methods, systems, and apparatuses are provided for estimating a location on an object in a three-dimensional scene. Multiple radiation patterns are produced by spatially modulating each of multiple first radiations with a distinct combination of one or more modulating structures, each first radiation having at least one of a distinct radiation path, a distinct source, a distinct source spectrum, or a distinct source polarization with respect to the other first radiations. The location on the object is illuminated with a portion of each of two or more of the radiation patterns, the location producing multiple object radiations, each object radiation produced in response to one of the multiple radiation patterns. Multiple measured values are produced by detecting the object radiations from the location on the object due to each pattern separately using one or more detector elements. The location on the object is estimated based on the multiple measured values.

The invention relates to a computer-implemented method for automatically extracting data from a scatter plot. The method comprises receiving a digital image of a scatter plot; analyzing the received digital image for identifying a plurality of pixel sets, each pixel set being a group of adjacent pixels; analyzing the pixel sets in the received image or in a derivative of the received image for generating a plurality of templates; comparing the templates with pixels of a target image for identifying matching templates; identifying data points for the identified similar templates; assigning to each identified data point a data series; and returning the identified data points.

A method and apparatus for mapping coded data symbols to resources in a mobile communication system. An S / P converter converts a serial signal including user data or control information into a plurality of parallel signals. A DFT unit performs Discrete Fourier Transform (DFT) on the parallel signals output from the S / P converter. A controller controls the DFT unit so that among the signals output from the S / P converter, a control channel is mapped in the maximum available resources to which the control channel can be mapped, among the resources included in a resource block, and data symbols are mapped to the remaining resources, except for the maximum available resources to which the control channel can be mapped. A subcarrier mapper allocates the signals output from the DFT unit to subcarriers. An RF processor converts a signal output from the subcarrier mapper into a radio signal.

The present invention relates to methods and systems for designing gauge patterns that are extremely sensitive to parameter variation, and thus robust against random and repetitive measurement errors in calibration of a lithographic process utilized to image a target design having a plurality of features. The method may include identifying most sensitive line width / pitch combination with optimal assist feature placement which leads to most sensitive CD (or other lithography response parameter) changes against lithography process parameter variations, such as wavefront aberration parameter variation. The method may also include designing gauges which have more than one test patterns, such that a combined response of the gauge can be tailored to generate a certain response to wavefront-related or other lithographic process parameters. The sensitivity against parameter variation leads to robust performance against random measurement error and / or any other measurement error.

The present invention generally relates to a digital imaging system or a light lens based imaging system. More specifically, the present invention provides an improved method and apparatus for calculating toner age and, additionally, carrier age using a toner concentration sensor and the amount of material dispensed. Both of these quantities can be used to ensure image quality by anticipating or diagnosing problems in image quality, which may be caused by toner age or carrier age.

A method for compressing a HOA signal being an input HOA representation with input time frames (C(k)) of HOA coefficient sequences comprises spatial HOA encoding of the input time frames and subsequent perceptual encoding and source encoding. Each input time frame is decomposed (802) into a frame of predominant sound signals (XPS(k−1)) and a frame of an ambient HOA component (CAMB (k−1)). The ambient HOA component (CAMB (k−1)) comprises, in a layered mode, first HOA coefficient sequences of the input HOA representation (cn(k−1)) in lower positions and second HOA coefficient sequences (CAMB,n(k−1)) in remaining higher positions. The second HOA coefficient sequences are part of an HOA representation of a residual between the input HOA representation and the HOA representation of the predominant sound signals.

The invention is related to a data loading method in a communication system where sub-carriers include eigenmodes, comprising, for instance: arranging eigenmodes into a predetermined number of clusters, each cluster comprising eigenmodes of different quality levels; pre-allocating transmission power to the eigenmodes with the aid of the calculated required power for achieving the approximated signal-to-noise ratio; determining collective transmission power to be allocated to each cluster based on the pre-allocation; allocating collective transmission power to the eigenmodes.

The invention relates to a system and a method for detecting an object of interest in a sequence of medical images. Said viewing system comprises alarm detection means (20) for detecting a set of alarms of said object of interest in a medical image (I′) at time t, in which an alarms is a set of data describing a possible location of the object. It further comprise temporal tracking means (30) for iteratively creating a set of tracks (T′) at time t by associating alarms of said set of alarms (A′) with tracks (T′1) at time t−1 and for choosing a track from among said set of tracks at time t in accordance with a merit criterion. Said track at time t is ended by an alarm which corresponds to a detection of said object of interest in said medical image at time t. Said viewing system advantageously accumulates temporal proofs for confirming or infirming spatial detections of alarms at time t. Detection of the object of interest is therefore made more robust to errors.
