A method and apparatus of interrogating an addressable array unit, which includes a substrate, a light reflecting layer on a front side of the substrate, and a plurality of features on a front side of the array. The method may include, for each of multiple features, illuminating the feature simultaneously with reflected and non-reflected interrogating light. A light emitted from respective features is detected. Either or both, constructive interference of interrogating light at the features, or constructive interference of light emitted from the features, can be obtained to allow lowering of light power from the source, enhanced signal, or reduced noise, or combinations of the foregoing. High depth discrimination may also be obtained without the need for a confocal detection system with conventional pinhole.

This patent provides a process that utilizes the vehicle to infrastructure communication process to gather anonymous vehicle trajectories that describe vehicles approaching a signalized intersection. This information is used to project forward in-time the positions of vehicles to calculate the optimal time to change the traffic signal at a point that will minimize the delay to the traffic.

The recycling of charge when two or more of the drive lines of a touch sensor panel are being simultaneously stimulated with the in-phase and anti-phase components of a stimulation signal is disclosed. To perform charge recycling, a discharge path can be selectively formed between drive lines being stimulated with the in-phase and anti-phase components of the stimulation signal. A multiplexer can be coupled to the driver of each drive line and the common discharge path. When charge recycling is to be performed, control logic can configure the multiplexers to isolate the driver and connect the drive lines being stimulated with the in-phase component of the stimulation signal with the drive lines being stimulated with the anti-phase component of the stimulation signal. The capacitance on the charged-up drive lines can then discharge to the capacitance on the discharged drive lines.

A position sensing device comprises a light source that radiates diffuse source light along an optical axis direction to a detector, and a moving aperture arrangement positioned between the source and detector, to move perpendicular to the optical axis direction. The moving aperture arrangement comprises first and second limiting apertures, which angularly filter and transmit the diffuse source light to form a measurement spot on the detector. At least one signal output by the detector is indicative of a position of the movable member along a measurement axis. The angular intensity distribution of the angularly filtered rays of light which form the measurement spot is more consistent as a function of position along the measurement axis than the angular intensity distribution of the source light. The resulting consistent intensity distribution within the measurement spot throughout the measurement range enhances measurement linearity and accuracy.

Method and apparatus for improving the detection and discrimination of slow moving or stationary range-Doppler spread objects on or in close proximity to the ground (or sea surface). Invention detects, discriminates and separates radar returns from interference including ground clutter discretes via a coherent process for separating target returns from the myriad of received signals. Thus the method and apparatus improves the probability of detecting and declaring the presence or absence of an object at the same time that the probability of false declaration decreases. The method and apparatus may be applied to the processing of any over resolved object, including airborne radar.

An electro-optical sensor for use with a retro-reflective target (10). The light-emitting assembly involves a LED (4) and collimating and parallel lenses (2, 4), and the sensing assembly involves a collecting lens (5), an aperture plate (6) and a photodiode array (7) with optional field-curvature correcting lens (8). The lens (5) abut the substrate (1) within the aperture of plate (6) so that the entrance pupil and the exit pupil, when viewed from the target (10), abut opposite, parallel straight-edges of the substrate (1). The photodiode array (7) may be a linear pixel array parallel to the substrate-surface, or may be replaced by a single, large-area photodiode with aperture-limitation of its field of view to a narrow fan-shape parallel to the substrate-surface. A plurality of light-emitters (77) may be used with photo-detectors (71) that have individual light-collection optics (72, 73) with merged fields of view. The sensor can sense golf club-head (100) movement and vehicle speed and plate number (116).

Methods and systems for operating an apertureless microscope for observing one or more features to a molecular sensitivity on objects are described. More particularly, the method includes moving a tip of a probe coupled to a cantilever in a vicinity of a feature of a sample, which emits one or more photons at a detected rate relative to a background rate of the sample based upon the presence of the tip of the probe in the vicinity of the feature. The method modifies the detected rate of the feature of the sample, whereupon the modifying of the detected rate causes the feature of the sample to enhance relative to background rate of the feature.

A technique is set forth that is designed to reduce RF induced power in high field MR imaging that includes application of an initial contrast preserving phase of RF pulses. These initial RF pulses are designed to have a constant, relatively high flip angle over the initial contrast preserving phase. Following an effective TE, a ramp down phase is applied that has a limited number of RF pulses with a flip angle that is less than the flip angle of those in the initial contrast preserving phase. Further, the RF pulses in the ramp down phase have a flip angle that is decreased over the ramp down phase. This technique provides improved resolution and steady contrast and SNR, while significantly reducing induced RF power.

A system for close range sonar is provided. The system provides sufficient warning to permit maneuvering to avoid a close encounter even in the forward starboard/port regions, which have been problematic in the past due to ownship noise. The system utilizes a hull mounted sonar array and a towed sonar array which may be controlled in position to provide sufficient separation of noise received by both sonar arrays such that the noise is largely uncorrelated. The system utilizes beamformers for each array to supply a cross-correlator section which is able to minimize the ownship noise and maximize the signal thereby providing more time for maneuvering. The system also provides a LOFAR display and other displays that are highly sensitive to detecting close encounters.

An analysis for determining a characteristic cycle time of a sample. Active elements in the sample are excited with sufficient intensity and duration larger than the characteristic cycle time that at least some of the active elements are re-excited to an excited state substantially immediately following relaxation to a ground state, detecting quanta emitted by the active elements in the sample to obtain a detected signal, and analyzing the detected signal to derive the characteristic cycle time. The number of active elements in the sample and the intensity of the excitation are such that quanta are detected in a stream in which individual quanta are distinguishable from each other.

A nano-sized CPP aperture is precisely positioned to within a few nanometers of a slider ABS surface to maximize a signal from the disk and to prevent lapping damage to the aperture itself. A linear array of apertures is aligned perpendicular to the ABS plane. The head resistance is monitored during lapping. Each time an aperture is lapped through, there is an increase in head resistance that is equal to the inverse of the total aperture area. There are three equal-sized apertures that are evenly spaced apart. When the first aperture is lapped through, there is a 50% increase in resistance, and a 100% increase in resistance when the second aperture is lapped through. These resistance increases are very large and are easy to distinguish from noise.
