Methods, systems and devices are described for rapid characterization and screening of liquid samples to determine properties (e.g., particle size, particle size distribution, molar mass and/or molar mass distribution) thereof with static light scattering and/or dynamic light scattering. The liquid samples can be solutions, emulsions, suspensions or dispersions. One method, includes providing a vessel containing a liquid sample having an exposed surface that defines a gas-liquid sample interface, and analyzing the sample by light scattering methods that include transmitting light through the gas-liquid sample interface into the sample, and detecting light scattered from the sample or from a component thereof. Additional methods are directed to characterizing a plurality of liquid samples or components thereof. The methods, systems, and devices have applications in high-throughput screening, and particularly, in combinatorial materials research and in industrial process control.

A ladar system can estimate intra-frame motion for an object within a field of view of the ladar system using a tight cluster of ladar pulses. For example, ladar pulses in a cluster can be spaced apart but overlapping with at least one of the other ladar pulses in that cluster at a specified distance in the field of view. A ladar receiver can then process the reflections from the cluster to computer intra-frame motion data, such as intra-frame velocity and intra-frame acceleration for an object.

An automated method for testing audio signal quality of cell phone transmissions provides a Mean Opinion Score (MOS) output using inexpensive test components. The test system uses a server computer to eliminate the need for expensive faders used in a bench test system. The server computer manipulates data packets from the reference media file to simulate impairments, including losses, errors, noise and jitter, at a much lower cost than using actual faders. Transmission through two separate radio access networks RANs is provided to simulate two parties communicating using separate mobile devices (an end-to-end test solution) with a single cell phone.

This invention provides a device and methods for the rapid detection and/or diagnosis and/or characterization of one or more allergies (e.g., causes IgE mediated allergic reaction (immediate hypersensitvity) in a mammal (e.g., a human or a non-human mammal). In certain embodiments, the device comprises a microcantilever array where different cantilevers comprising the array bear different antigens. Binding of IgE to the antigen on a cantilever causes bending of the cantilever which can be readily detected.

Disclosed herein are examples of ladar systems and methods where data about a plurality of ladar returns from prior ladar pulse shots gets stored in a spatial index that associates ladar return data with corresponding locations in a coordinate space to which the ladar return data pertain. This spatial index can then be accessed by a processor to retrieve ladar return data for locations in the coordinate space that are near a range point to be targeted by the ladar system with a new ladar pulse shot. This nearby prior ladar return data can then be analyzed by the ladar system to help adapt a shot selection for use by the ladar system with respect to new ladar pulse shots.

A system and a method of detecting and characterizing a bacterial colony are presented in which the results are determined within about 48 hours. The bacterial colony is disposed on a substrate and placed between a laser and detector. Light from the laser impinges upon and is scattered by the bacterial colony. The forward scattered light is detected by an optical detector. The signal from the optical detector is analyzed by an analyzer and displayed or supplied to a storage medium for review. As different strains of bacteria possess unique forward scattering fingerprints, the particular strain may be identified.

Characterization of an optical system is quickly and easily obtained in a single acquisition step by obtaining image data within a volume of image space. A reticle and image plane are positioned obliquely with respect to each other such that a reticle having a plurality of feature sets thereon, including periodic patterns or gratings, is imaged in a volume of space, including the depth of focus. Metrology tools are used to analyze the detected or recorded image in the volume of space through the depth of focus in a single step or exposure to determine the imaging characteristics of an optical system. Focus, field curvature, astigmatism, spherical, coma, and/or focal plane deviations can be determined. The present invention is particularly applicable to semiconductor manufacturing and photolithographic techniques used therein, and is able to quickly characterize an optical system in a single exposure with dramatically increased data quality and continuous coverage of the full parameter space. In embodiments, the test reticle is holographically generated by interfering two or more beams of optical radiation. The resulting interference pattern is recorded on a reticle and used for testing the optical system. The geometry of the holographic interference pattern is tightly controlled by the properties of the interfering beams and is therefore more accurate than conventional reticle writing techniques.
