Abstract:
The present invention provides an apparatus and a method wherein the movement of analytes on a chromatographic separation column is controlled by the manipulation of isocratic and gradient flow. Such manipulation allows for a distinct set of analytes to be eluted from the chromatography column and delivered downstream for further separation and/or processing while the remainder of the sample remains in a “holding pattern” on the chromatography column. As such, the present invention allows for a small portion of the sample to be processed downstream of the column while substantially eliminating undesirable isocratic elution from the column during such downstream processing. Once the downstream processing has been completed, the column of the present invention elutes a second distinct analyte and the remainder of the sample is maintained in a holding pattern. The process may be repeated until the entire sample has been eluted from the chromatography column.

Abstract:
Described herein is a system that includes a receiver component that receives gesture data from a sensor unit that is coupled to a body of a gloveless user, wherein the gesture data is indicative of a bodily gesture of the user, wherein the bodily gesture comprises movement pertaining to at least one limb of the gloveless user. The system further includes a location determiner component that determines location of the bodily gesture with respect to a touch-sensitive display apparatus. The system also includes a display component that causes the touch-sensitive display apparatus to display an image based at least in part upon the received gesture data and the determined location of the bodily gesture with respect to the touch-sensitive display apparatus.

Abstract:
A method for detecting a two-dimensional bar code pattern using a bar code pattern reader, the bar code pattern being in the form of a matrix of rows and columns of data cells of either a first or second colour representing encoded data bits, and containing a set of at least two predetermined locating symbols at predetermined positions within the bar code pattern, wherein the method comprises the steps of: receiving a two-dimensional image containing the pattern, analysing the image to identify potential occurrences of the locating symbols within the image, validating the potential occurrences of locating symbols by analysing the potential occurrences to identify any set of occurrences whose size and relative positions within the image are consistent with the predetermined positions of the locating symbols within the bar code pattern, thereby identifying a set of locating symbols, and identifying the location of the bar code pattern within the image on the basis of the positions of the identified locating symbols. An apparatus for carrying out the method, and systems which utilise the bar code pattern, are also disclosed.
