101results about How to "Fast readout" patented technology

An iris imaging system used for biometric identification provides a combined iris imager and wavefront sensor. The detector array allows for independent readout of different regions, such that a wavefront sensor region can be read out fast while allowing signal to integrate on the iris imaging region. Alternatively, the entire array may be used for wavefront sensing during an acquisition phase, and then at least a portion of the array may be switched to be used for iris imaging during a subsequent imaging phase. An optical periscope optionally allows various optics to be inserted in front of the combined iris imager and wavefront sensor. In another embodiment, the glint image of an on-axis or near on-axis illumination source is picked off at the image plane and directed to the wavefront sensor optics, while allowing all of the light from the iris field to pass through to the iris imaging camera.

An electronic image stabilizer in a digital camera compensates for camera motion-induced blurriness by segmenting exposure times into multiple shorter exposure times and summing the individual pixels from successive frames after applying an appropriate motion correction. Motion is detected by computing the correlation function between successive images, and compensation is applied by maximizing the correlation function. This avoids the need for mechanical stabilization devices in order to detect or correct the motion as is done in prior art. This method further enables the detection of moving objects in a still background, and correction of blurriness images due to such motion.

A method and apparatus are provided for aligning optical elements or microbeads, wherein each microbead has an elongated body with a code embedded therein along a longitudinal axis thereof to be read by a code reading device. The microbeads are aligned with a positioning device so the longitudinal axis of the microbeads is positioned in a fixed orientation relative to the code reading device. The microbeads are typically cylindrically shaped glass beads between 25 and 250 microns (μm) in diameter and between 100 and 500 μm long, and have a holographic code embedded in the central region of the bead, which is used to identify it from the rest of the beads in a batch of beads with many different chemical probes. A cross reference is used to determine which probe is attached to which bead, thus allowing the researcher to correlate the chemical content on each bead with the measured fluorescence signal. Because the code consists of a diffraction grating typically disposed along an axis, there is a particular alignment required between the incident readout laser beam and the readout detector in two of the three rotational axes. The third axis, rotation about the center axis of the cylinder, is azimuthally symmetric and therefore does not require alignment.

The disclosure provides an apparatus and method for assessing brain plasticity by measuring electrical brain biomarkers, for example, with a near real-time analysis of electrical brain biomarkers, where an increase or decrease in at least one biomarker is indicative of a state of brain plasticity in response to a stimulus or treatment. Brain plasticity can be measured with or without an added stimuli, for example, to determine the best time for learning. Also provided is a method for treating a neurological disease or trauma by applying an electrical or drug stimulus to a patient, where the stimulus is increased or decreased depending on the changes of electrical brain biomarker of the patient. This treatment can occur in near real-time, so a course of treatment can be tailored immediately to a patient's needs.
