The invention relates to automatic eye tracking, wherein at least one imaging device (150) registers sequential image data (D_EYE) representing at least one eye (181; 182) of a subject (180). A processing unit (170) receives the image data (D_EYE), and based thereon, produces a position estimate of the at least one eye (181; 182). The processing unit (170) also produces a control signal (D_ILL)>which is received by at least one light source (140).

A vehicle tracking system for a vehicle is configured to track a remote vehicle by template matching between a reference image and an input image obtained by a camera mounted on the vehicle. The position and distance of a remote vehicle is determined by calculating a position and an enlargement/reduction ratio of a portion of the input image that provide a maximum correlation value between the portion of the input image and the reference template that is greater than a threshold value. The reference template is updated by calculating a dispersion of at least one pixel of the reference template with respect to a corresponding pixel in a vehicle image extracted from the input image that provides the maximum correlation value, and by deleting the at least one pixel when the dispersion of the at least one pixel is equal to or greater than a threshold value.

A position identifying system (1) is comprised of a radio terminal device (2) carried by a monitoring target and a sensor device (3) provided with a radio communication unit (9) for communicating by radio with the radio terminal device (2) and a camera unit (10) for taking an image of the monitoring target. In the sensor device (3), the position (tag position) of the radio terminal device (2) is detected on the basis of a detection signal from the radio terminal device (2), and the position (image position) of the monitoring target is calculated on the basis of the image taken by the camera unit (3). By linking the tag position with the image position, the position of the monitoring target is identified. Thus, there is provided the position identifying system capable of identifying the position of the monitoring target and keeping track of the movement of the monitoring target even if the image of the monitoring target cannot be taken.

Transducer elements of recording heads for magnetic storage media are moved independently in either of two directions with respect to the slider of the recording head. The motion is controlled using a micropositioner having magnetic coils integrated into the recording head. The transducer moves in the x direction between data tracks and in the z direction perpendicular to the surface of the magnetic storage medium. The micropositioners are used for small-scale positioning of the transducers over data tracks and to adjust fly heights. Because of the high minimum resonant frequencies and the low mass of the transducers, the micropositioners also improve settling times associated with track following. The micropositioners can be used during fabrication for dimensional control of recording head components. The motion of the transducers in the z direction enables the recording heads to be used reliably in the presence of asperities and changing ambient pressures and temperatures.

The present invention relates to automatic registration and tracking of the eyes of at least one subject. An optical system, including a lens structure, a mask and an image sensor, receives incoming light from a scene containing the subject and directs at least a portion of this light towards the image sensor, which registers spatially distributed light and thus produces primary data. The mask is adapted to alter a basic optical transfer function of the lens structure and the image sensor into an enhanced optical transfer function, which is substantially less sensitive to variations of an unknown distance between the optical system and the subject than the basic optical transfer function. The processing unit is adapted to receive the primary data and process this data to produce resulting eye-tracking data representing a position estimate of the at least one eye and/or a gaze direction for the at least one eye.

An automatically tracking scanning sonar alternately performs horizontal scanning and vertical scanning and a target lock processor calculates a predicted position of a target based on an echo signal previously received from the target when the echo signal from the target is interrupted. A selector sets a range, tilt angle and sounding direction and outputs them to a transmit-receive controller such that the scanning sonar can scan the predicted target position. As the depth of the target is determined by performing the vertical scanning, the tilt angle of an umbrellalike beam pattern produced by the horizontal scanning can be varied to follow the target by controlling the tilt angle based on target depth information even when the target moves in vertical directions. It is therefore possible to automatically track the target in a reliable fashion.

The invention belongs to the technical field of multisource information fusion, and discloses a flight path fusion method. The flight path fusion method comprises the following steps of: establishing a relative distance matrix between data by using observation information of a plurality of sensors; computing a support threshold function to obtain a support threshold matrix, establishing an equation set, and solving a weighting factor; multiplying the weighting factor with a corresponding observed value, obtaining corresponding filter values respectively through filtering, and adding all obtained filter values to obtain a filter fusion value with an observation coefficient; and updating an estimated value of target state step by step by using Kalman filtering, wherein the filter fusion value serves as a state updating input value. In the invention, as the filter fusion of the observation coefficient is carried out through the observation information of the plurality of sensors, influence on the fusion of flight paths due to the uncertainty of the observation information is reduced under the condition that data processing complexity is not increased; and correlation of the observation information is taken into consideration during the filter fusion of the observation coefficient, so that observation accuracy is increased, and the reliable tracking of a target is obtained.
