Title: Method and device for determining the intraocular pressure, by measuring the changing of the frequency characteristics
Inventor: LINDAHL OLOF
IPC: A61B3/16
Filed: 2000-08-24
Abstract: The present invention relates to a method and a device for measuring the pressure p in an eye, the so-called intraocular pressure. The method includes a contact body with a known geometry being pressed against the eye with a gradually increasing contact force F and that when the area of deformation of the eye A can be determined, the pressure can be obtained from the relation P=F/A, whereby the frequency characteristic of a contact body associated with a sensor system oscillating in resonance is read, the contact body is pressed against the eye to form a new system oscillating in resonance, the contact force and frequency characteristic for the new system is read, and the change in frequency characteristic is calculated. In this way, the pressure of the eye can be determined since the sought deformation area A is a function of the change A(fch ar). The device has a contact body (4) for pressing against the eye (1) and a means (3) of determining the force with which the contact body is pressed against the eye, whereby the contact body (4) is part of a system oscillating in resonance, and the resonance system is connected to a means (9) for reading the frequency characteristic of the system.

Title: Neural control system and method for alternatively fueled engines
Inventor: SULATISKY MICHAEL THEODORE
IPC: F02M21/02
Filed: 2003-03-19
Abstract: A powertrain controller of a vehicle provides fuel injection pulses based on gasoline operation. The pulse widths of the fuel injection pulses are modified with reference to air temperature, engine speed, and exhaust gas oxygen (EGO) content to control fuel injectors for an alternative fuel such as natural gas. The EGO content, based on alternative fuel operation, is detected and compared to a desired air-fuel ratio or desired fuel trims to provide error information that is used to adjust the modification of the pulse widths. In response to the error information, a neural network (as an example) dynamically adjust the pulse widths of the alternative fuel injection based on the weights of measured, detected engine speed, EGO, universal exhaust gas oxygen, or air temperatures. The engine operating on alternative fuel is provided with the proper mixture of alternative fuel and air to respond to various engine loads and meet emission standards.

IPC: G01N33/34
Filed: 2002-01-28
Abstract: A system and process for measuring paper formation characteristics in real time is disclosed. The system comprises apparatus used in a papermaking process, and includes a rotating forming fabric having an upper and lower surface. A paper slurry is deposited upon the upper surface of the moving forming fabric to prepare a wet paper web.

Title: Methods for identifying small molecules that bind specific rna structural motifs
Inventor: WELCH ELLEN
IPC: G01N33/566
Filed: 2002-04-11
Abstract: The present invention relates to a method for screening and identifying test compounds that bind to a preselected target ribonucleic acid ("RNA"). Direct, non-competitive binding assays are advantageously used to screen libraries of compounds for those that selectively bind to a preselected target RNA. Binding of target RNA molecules to a particular test compound is detected using any physical method that measures the altered physical property of the target RNA  bound to a test compound. The structure of the test compound attached to the labeled RNA is also determined. The methods used will depend, in part, on the nature of the library screened. The methods of the present invention provide a simple, sensitive assay for high-throughput screening of libraries of compounds to identify pharmaceutical leads.
