Title: A method and apparatus for monitoring a condition in chlorophyll containing matter
Inventor: HARRISON PETER
IPC: G01N21/64
Filed: 2001-07-06
Abstract: A method of monitoring health in chlorophyll containing matter comprises exposing the matter to a light source to cause chlorophyll to fluoresce and emit a fluorescence signal. Any changes in a parameter indicative of changes in the intensity of the fluorescence signal are detected and compared with a predetermined threshold. A change which exceeds the predetermined threshold is interpreted as a transition of the level of stress in the chlorophyll containing matter. An apparatus for monitoring health in chlorophyll containing matter is also provided and comprises a light source for causing chlorophyll in the matter to fluoresce, a detector for detecting the intensity the fluorescent signal, means for measuring changes in a parameter indicative of changes in the intensity of the fluorescent signal and a detector to detect an increase in the change of the parameter above a predetermined threshold.

Abstract: The present invention provides systems and methods for simulating certain regions of the anatomy involved in ophthalmological surgery. In particular, the present invention provides a practice cornea simulating dimensional, geometric and mechanical properties of a human cornea. In one embodiment, the practice cornea is seated in tight apposition to a simulated iris that is characterized by dimensional and geometric properties similar to a human iris.  The practice cornea seated upon the simulated iris may be inserted into an aperture in a simulated sclera, forming therewith a smooth surface similar to that found in the anterior part of the human eye. The simulated sclera may be provided with dimensional and geometric characteristics resembling the human sclera.

A server (108, 109, 113) recognizes the request for a finite bandwidth and approves the request, if capacity permits . Once a request has been approved, the systems and methods consistent with th is disclosure provide for reserved access to transmission bandwidth in a communications channel to support real-time network applications, including transactions involving wireless local area networks (103), cellular networks  (104), and ad hoc networks (102).

Title: Anonymous trading system
Inventor: NEYMAN VLADIMIR
IPC: G06Q40/00
Filed: 2001-06-21
Abstract: An anonymous trading system comprises a number of branches of broking nodes, each broking node having one or more bank nodes connected to it through which trader terminals connected to the bank nodes can input price quotation messages into the system and receive market views. At the top of each branch is an arbitrator performing price matching and the broker nodes each perform the tasks of price matching, deal execution and price distribution. The branches are hierarchical such that matching is first attempted at the broking node at which a price quotation enters the system and matching is then attempted successively at the next upstream broking node. If no match is made the quote is passed to the arbitrator at the top of the branch which then attempts to match it with quotes from other branches.

Title: The identification and use of effectors and allosteric molecules for the alteration of gene expression
Inventor: MARSHALL WILLIAM S
IPC: C12Q1/68
Filed: 2001-03-01
Abstract: The present invention relates to the construction of an allosteric control module in which a catalytic RNA forms a part of or is linked to an effector- binding RNA domain or aptamer. These constructs place the activity of the catalytic RNA under the control of the effector and require the presence of an appropriate effector for activation or inactivation. The present invention provides means to identify useful effector molecules as well as their use to  evolve cognate aptamers. The invention involves both the evolution of RNA sequences which bind the effector and a selection proces in which the allosteric control modules are identified by their catalytic function in the  presence and absence of the effector. The resulting regulatable catalytic RN As may be used to alter the expression of a target RNA molecule in a controlled  fashion.
