Title: Method and apparatus for acquiring and organizing ink information in penaware computer systems
Inventor: YAEGER LARRY S
IPC: G06K9/62
Filed: 2000-12-18
Abstract: An ink manager running at a computer system receives ink information entered at a pen-based input/display device and accumulates the ink information into ink strokes. The ink manager communicates with a handwriting recognition engine and includes an ink phrase termination engine that is configured to detect the occurence of one or more ink phrase termination events by examining the ink information. Upon the occurrence of an ink phrase termination event, the ink manager notifies the handwriting recognition engine and organizes the preceding ink strokes into an ink phrase data structure. The ink manager may also pass the ink phrase to an application executing on the computer system that is associated with the ink information, and it, in response, may return a reference pointer and a recognition context to the ink manager. The reference pointer and recognition context are then appended to the ink phrase data structure. Utilizing the recognition context identified by the application, the handwriting recognition engine generates one or more hypotheses for the ink phrase, and provides them to the ink manager. The ink manager forwards the hypotheses together with the reference pointer to the application and may also append them to the ink phrase data structure.

Title: System and method of amplifier gain control by variable bias and degeneration
Inventor: LEIFSO CURTIS R
IPC: H03F3/45
Filed: 2003-04-16
Abstract: A gain control circuit that permits a variable gain amplifier circuit to operate with high input linearity and low power consumption is disclosed. The variable gain amplifier includes a standard differential bipolar transistor input circuit and a pair of degeneration transistors connected to a current source transistor. The gain control circuit provides a variable degeneration control voltage to vary the effective resistance of the degeneration transistors and a variable bias voltage to vary the current of the current source transistor. The input linearity of the variable gain amplifier is controlled independently of gain by adjusting the effective resistance and the current in an inverse relationship such that at maximum gain the current is at a maximum while the degeneration resistance is at a minimum, and at minimum gain the current is at a minimum while the degeneration resistance is at a maximum. Therefore the variable gain amplifier can be controlled to operate with high input linearity and low power at lower ranges of gain.

Title: Method for the amplification and optional characterisation of nucleic acids
Inventor: COLLINS RUAIRI
IPC: C12Q1/682
Filed: 2001-11-01
Abstract: A method for the amplification of a template nucleic acid comprises simultaneously carrying out the steps of reacting a nucleic acid primer with said template nucleic acid, normal DNA precursor nucleotides, at least one modified DNA precursor nucleotide and a DNA polymerase so as to obtain an extended nucleic acid primer, said nucleic acid primer remaining bound to said template; cleaving the modified base-containing extended nucleic acid primer so as to generate a free 3'-OH terminus that is extensible by said DNA polymerase; and repeating steps i) and ii) on DNA fragments thereby generated. The modified precursor nucleotide may be a substrate for a DNA glycosylase or recognised by a 3'-endonulcease and determines the cleavage of the DNA and the site of the cleavage accordingly. The method has significant advantages over existing technologies in that it is more versatile and more flexible with respect to providing a single high throughput process that can be easily adapted to multiple different formats in the fields of DNA detection, quantitation and characterisation.
