A method, system, and computer program product are provided, wherein the bandwidth necessary to transmit an item of image data is reduced. When items of image data are identified in a datastream, they are extracted from the datastream. The image data item is then divided into a series of subregions of variable size. Where efficiency dictates that the operation is appropriate, the subregions are replaced in the image data item with a unique identifier to produce a reduced image. The reduced image is then packaged into a new data structure containing a header, the reduced image, and a decoding table that will allow the replacement of the identifiers with the extracted subregions. Where subregions are repeated, as they frequently are in images of large size, this arrangement will allow for the compression of the image by the elimination of redundant data that merely represents a repeated subregions. When the image reaches its destination, the it is decoded to reproduce the original image.

Apparatus and methods for exciting and detecting fluorescence in samples are disclosed. In one embodiment, a sample holder for holding a plurality of samples is provided together with an optical manifold having an excitation source, a photo receiver, or both, for each of the plurality of samples. In another embodiment, the optical manifold contains only the excitation source or a photo receiver, and the other is associated with the sample holder. This system permits for rapid excitation and measurement of fluorescence without the use of moving parts and without any opto-mechanical or electronic disturbance. It exhibits an exceptional signal to noise ratio, which permits it to differentiate between very low level differences in fluorescence.
摘要:
A method and apparatus for managing complex presentation objects using globally-unique identifiers. Downloaded objects are identified by globally-unique identifiers to maintain object integrity and to facilitate capturing downloaded objects for reuse without additional download time overhead. An object may be referenced by selected indicia, such as a name, a globally-unique identifier or a globally-unique identifier and an object locator, The object is located by the selected indicia. Then, a decision is made whether to allow capture of the object based upon whether the selected indicia includes a globally-unique identifier and is secure.
摘要:
A rug cleaning apparatus to rinse, decontaminate and evacuate fluid or undesirable particulates from the rug with enhanced efficiency is provided. The cleaning apparatus includes a tubular member having a first end, a second end and a side wall, the tubular member having a plurality of openings disposed thereto evenly throughout the side wall, a cap coupled to the second end of the tubular member, and a vacuum coupled to the first end of the tubular member. The tubular member permits the rug to be disposed around the side wall. The vacuum activates to generate sufficient airflow and pressure within the tubular member to draw fluid or undesirable particulates in the rug through the openings of the tubular member and out to the vacuum for a disposal.

摘要:
Apparatus and methods for amplification of DNA are provided that use sonic energy in place of conventional thermocyclers. In one embodiment, sonic energy is applied to a PCR cocktail to effect dissociation of double stranded DNA into single strands of DNA. A quiescence stage, where no sonic energy is applied, results in amplification of DNA. Repetition of the cycles of application of sonic energy and cessation of application of sonic energy results in DNA amplification.
