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.

A method for providing a camera calibration includes recovering geometric information from a single rectangular image, obtaining intrinsic and extrinsic construction information of a camera based on the recovered geometric information, obtaining a shooting position and real geometric information of the camera from the obtained intrinsic and extrinsic construction information of the camera.

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.

The present invention relates to determining a trajectory of a target from two streams of images obtained from two sources of images, a sub-image of each of the images of the two streams of images representing an overlapping area of a real scene. After having obtained a target path for each of a plurality of targets, from images of the sources of images, for each of the two streams of images, each target path being obtained from a target tracker associated with a source of image, each of the obtained target paths is split into a plurality of target path portions as a function of each potential target switch along the obtained target path. Then, the trajectory is generated as a function of a plurality of the target path portions.

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.

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.

An apparatus includes a device having n input ports and n output ports. The n input ports are configured to receive n corresponding physical objects of a physically processed, quantum redundancy coded state. The n output ports are configured to output the n physical objects in the physically processed, quantum redundancy coded state. The device is configured to measure bits of a syndrome of the physically processed, quantum redundancy coded state by passing the n physical objects through the device. The device is configured to measure a parity check bit for the measured bits of the syndrome by the passing the n physical objects through the device.
