A query server of a mobile search engine system for searching content items accessible online, is arranged to send at least a first screenview of search results (63) to a browser of a mobile device (10), and send instructions (69, 74) in a scripting language to the browser for a background process to fetch further search results to the mobile device for presentation later. The further search results can then be viewed as desired without the need for a further round trip delay across the wireless network. The user can be presented with a simpler navigation model. The first screenview can be sent in the form of a page formatting template, and results data. The formatting information can be reused for other results, to reduce formatting overhead in the downloads. The instructions can also be used for showing information while waiting for downloads, or downloading information during entry of search queries.

Fast approximate focus operations providing an approximately focused image that is sufficiently focused to support certain subsequent inspection operations. The operations are particularly advantageous when used to provide images for successive inspection operations that predominate when inspecting planar workpieces. Improved inspection throughput is provided because, in contrast to conventional autofocus operations, the fast approximate focus operations do not acquire an image stack during a run mode as a basis for determining a best focused image. Rather, during learn mode, a representative feature-specific focus curve and a focus threshold value are determined and used during run mode to provide an approximately focused image that reliably supports certain inspection operations. In one embodiment, an acceptable approximately focused inspection image is provided within a limit of two focus adjustment moves that provide two corresponding images. The adjustment moves are based on the representative feature-specific focus curve provided in learn mode.

One embodiment of the present invention distributes data via a network to remotely located individuals.

The evaluation feedback may be in the form of ratings of product reviews. The feedback helps customers by allowing the more useful reviews can be quickly located.

Highly efficient and rapid filtration-based concentration devices, systems and methods are disclosed with sample fluidic lines and a filter packaged in a disposable tip which concentrate biological particles that are suspended in liquid from a dilute feed suspension. A sample concentrate or retentate suspension is retained while eliminating the separated fluid in a separate flow stream. The concentrate is then dispensed from the disposable tip in a set volume of elution fluid. Suspended biological particles include such materials as proteins / toxins, viruses, DNA, and / or bacteria in the size range of approximately 0.001 micron to 20 microns diameter. Concentration of these particles is advantageous for detection of target particles in a dilute suspension, because concentrating them into a small volume makes them easier to detect. All conduits by which the disposable tip attaches to the instrument are combined into a single connection point on the upper end of the tip.

Systems and methods are disclosed for vehicle motion planning where a sensor, such as a ladar system, is used to detect threatening or anomalous conditions within the sensor's field of view so that priority warning data about such conditions can be inserted at low latency into the motion planning loop of a motion planning computer system for the vehicle. The ladar system can perform compressive sensing to target the field of view with a plurality of ladar pulses.

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.

A compressive imaging system and method for quickly detecting spectrally and spatially localized events (such as explosions or gun discharges) occurring within the field of view. An incident light stream is modulated with a temporal sequence of spatial patterns. The wavelength components in the modulated light stream are spatially separated, e.g., using a diffractive element. An array of photodetectors is used to convert subsets of the wavelength components into respective signals. An image representing the field of view may be reconstructed based on samples from some or all the signals. A selected subset of the signals are monitored to detect event occurrences, e.g., by detecting sudden changes in intensity. When the event is detected, sample data from the selected subset of signals may be analyzed to determine the event location within the field of view. The event location may be highlighted in an image being generated by the imaging system.

This invention relates in general to methods and systems of rapid focusing and zooming for the applications in the projection of volumetric 3D images and in the imaging of 3D objects. Rapid variable focusing or zooming is achieved by rapid and repeated change of the object distance or the spacing between lens groups of the projection lens or a combination of both. One preferred approach inserts thin wedge prisms into the optical path and changes their positions relative to the optical path. This changes the thickness traveled through by the optical path and results in effective optical path length change. Another approach folds an optical path by mirrors and moves the mirrors to change the optical path length. For focusing purpose, small and precise displacement is achieved by moving a wedge-shaped optical device obliquely with respect to the optical path. The wedge-shaped optical device can be a thin wedge prism or a mirror on a wedge-shaped base. Optical layout analysis shows that the changes of the object distance, of the spacing between two lens groups and of the image distance are almost in proportion and can be correlated by linear relations. Therefore, the same type of motion function can be used to change these three optical path lengths to achieve focusing and constant magnification.

The photographing method comprises the steps of: detecting whether an ambient brightness value of a scene to be photographed is within a preset brightness range; if so, controlling the first camera to perform focusing processing on the scene to be photographed, and transmitting the obtained focusing information to the second camera; controlling the second camera to perform focusing according to the focusing information; and controlling the second camera to acquiring first image information of the scene to be photographed after the second camera finishes focusing, wherein the photographic sensitivity of the first camera is higher than that of the second camera. According to the photographing method, the first camera with high photographic sensitivity is started for focusing under the specific brightness condition and sends focusing parameters to the second camera, so that the second camera can perform focusing and acquire images according to the focusing parameters, thereby solving the problem that clear pictures cannot be photographed due to low ambient brightness.
