Patents on Algorithms. Whereas until recently much of the analysis of data in pharmaceutical research and development was carried out essentially by manual processes, the volume of data that is currently being generated means that increasingly sophisticated algorithms are being used to order, sort, and analyze the data. 

A marker substance is injected into a central vein. A peripheral arterial line is used to measure the amount of the substance in the arterial system. A graph of concentration versus time is produced and patented algorithms based on the Stewart-Hamilton equation (below) are used to calculate the cardiac output.

There are nonzero chances that the charge flipping algorithm may make direct methods obsolete. Performing as it is, the algorithm is obscure in its fundamentals. No equations, formulas, or proofs are proposed or derived. In the authors own words [14] we admit our own lack of understanding of it beyond the level of intuition. This is a patent case in which the human brain is almost made superfluous by fast computing. Indeed, this facet of scientific activity has few precedents. 

The sensor consists of a patented resonator which is designed to have one side make physical contact with the sample under test The shift in resonant frequency of the cavity, as well as the change in amplitude of reflection are a measure of the dielectric properties, e and e" of the sample. By measuring these two parameters and correlating them to process parameters, one is able to develop an algorithm which can be used for process monitoring. 

The first publication about the computer translation of chemical names was published by Garfield in 1961. In that article, he described the conversion of names into chemical formulas and initiated the path toward N2S algorithm development.45 Developments in 1967 at CAS provided internal procedures for the automatic conversion of CAS names into chemical diagrams.46 47 The first commercially available software program was CambridgeSoft s Name=Struct released in 1999,48 now patented,49 which was followed shortly by ACD/Labs ACD/Name to Structure product released in 2000.50 Two more commercial products are available Chemlnnovation s NameExpert51 and...
