摘要： The invention generally relates to systems and methods for eye detection for use in, for example, installations and systems for tracking eyes and gaze angle/directions. The system includes a plurality of eye detection units connected to an image sensor. The eye detection units are adapted to receive regions of picture elements of a digital image frame substantially in parallel and wherein the eye detection units are adapted to operate substantially in parallel, each eye detection unit being adapted to receive a specified region of the picture elements of at least one digital image frame and including an eye feature extraction module adapted to perform a eye feature extraction process on the received picture elements to identify predetermined eye features. An eye data generating module is adapted to receive information of potential identified eye features including picture element coordinates for the identified eye features, and the received region of picture elements, and generate eye data based on the information of potential eye features, wherein the eye data is generated if identified eye features fulfill predetermined conditions, and transfer generated eye data and the received regions of picture elements to a processing module, and wherein a data flow of the eye data and the region of picture elements of a digital image frame is substantially parallel.

摘要： A monitoring system monitors and/or predicts drowsiness of a driver of a vehicle or a machine operator. A set of infrared or near infrared light sources is arranged such that an amount of the light emitted from the light source strikes an eye of the driver or operator. The light that impinges on the eye of the driver or operator forms a virtual image of the signal sources on the eye, including the sclera and/or cornea. An image sensor obtains consecutive images capturing the reflected light. Each image contains glints from at least a subset or from all of the light sources. A drowsiness index can be determined based on the extracted information of the glints of the sequence of images. The drowsiness index indicates a degree of drowsiness of the driver or operator.

摘要： A method for processing a signal includes monitoring an over-sampled signal to detect deviations in a number of fill samples, and providing an electronic delay adjustment to a signal path. If a deviation in the number of fill samples is detected, the electronic delay adjustment from the signal path is removed in one or more steps until all of the electronic delay adjustment is removed from the signal path.
