Inventors and Patents From the City of Lisle

The list of patents issued to Lisle residents includes a variety of products. Some of the products are medical or industrial and are used to improve human health. Another invention is a system for analyzing object simulation data. Several companies in the region have also been granted patents.

Tellabs Operations, Naperville, Ill., has been assigned a patent for a “reverse notification tree for data networks”

The patent covers methods and apparatus for detecting a failure in a passive optical network. Co-inventors are James D. Jacobson of Lindenhurst, Ill.; Tuan Bui of Green Oaks, Ill.; and Atif Yardimci of Vernon Hills, Ill. The patent was filed on Nov. 8, 2008.

The patent also covers an RNT that is associated with working paths. In this system, each switch can remember its upstream neighbors. Then, it can merge these upstream neighbors into one working path and exit as a single working path. The invention also describes data structures stored in memory that identify switches in a working path.

Another patent was recently granted to Tellabs Operations. This invention is an improved version of a method for managing data network usage. It is based on an invention by Kajeet. The patent was filed on March 21, 2010 and covers a system and method for managing utilization of communications devices.

The invention has received a patent number of seven,881,184. Co-inventors include John E. Jones, Winnetka, Ill.; Christopher A. Dybek of Wyanet; and William H. Eichhorn of Glenview.

Two other companies have filed patent applications for similar ideas. One of these companies, Coramed Technologies of West Chicago, Ill., has been assigned a patent (7,880,026).

In another patent, Tellabs Operations, Naperville, Illinois has been assigned a patent for a reverse notification tree. This method re-routes downstream messages and data onto a protection path. The protection path is a different transmission path, and may even use different transmission media.

Another company, Tellabs Operations, Naperville, Illinois-based Tellabs, has been awarded a patent for a “reverse notifications tree for data networks” that allows for a network to be more reliable and responsive.

The technology is similar to that used in wireless communications. It is based on a “reverse notification tree” – a protocol that sends periodic updates to data networks. Tellabs’ patent application was filed on Aug. 25, 2006 (11/510,193) and subsequently on Feb. 3, 2009 (12/364,917).

A “reverse notification tree” enables network administrators to notify all affected downstream switches of a fault. This method minimizes network recovery time by sending a notification over a reverse path of working paths.

Boeing, Chicago, has been assigned a patent for a “barrier coatings for polymeric substrates”

The patent, which covers the use of barrier coatings on polymeric substrates, was developed by Boeing. It was assigned to four co-inventors, including Boeing’s James H. Mabe and Frederick T. Calkins, who live in Westlake Village, Wash.; and Glenn S. Bushnell and Stefan R. Bieniawski of Bellevue, Wash. The patent application was originally filed on July 21, 2005.

The patent covers methods of applying barrier coatings to polymeric substrates for various purposes. This technology can be used to protect polymeric substrates from damage and ensure long-term reliability. The company has been developing such technology for the past several years.

The company has also developed an aerosole using a polymer material. The invention consists of monodisperse mesoporous silica microspheres produced from surfactant templates in an aerosole. The inventors of this patent include Timothy L. Ward, Jaime Bravo, Abhaya Datye, Gabriel Lopez, and Hien Pham of Albuquerque.

Among other patents issued to aircraft companies, a new one relating to air-to-air aftercoolers was recently granted to Caterpillar Inc. for a method of forming a container with improved release properties. The patent application, no. 7,877,968, was filed on Aug. 14, 2007.

The company has also received patents for a pallet sheet. The patent, which was developed by five co-inventors, describes a pallet sheet with oppositely oriented cleats. The company is based in Hawthorn Woods, Ill.

Lockheed Martin, Chicago, has also been granted a patent for the same technology. The company filed its patent application for “barrier coatings for polymeric substances.” It was awarded the patent on Dec. 8, 2008. The inventors are:

Another patent assigned to Boeing is D631,863, developed by Cheol Woo Park and Ruben D. Castano. It was filed on Dec. 30, 2007. A similar patent was issued to Tippmann Sports, Glenview, Ill.

Barrier-coated polymeric substrates outperform glass in several physical tests. In fact, they have been shown to have less strain-to-failure than glass, which is a major concern for aircraft windows.

Abbott Laboratories has been assigned a patent for inhibiting an enzyme

Abbott has a patent on a drug that binds to an enzyme called a protease. The drug is called Norvir and is used to treat HIV, the virus that causes acquired immune deficiency syndrome (AIDS). It is a protease inhibitor that helps the immune system fight off HIV. However, it is known to have severe side effects when taken alone, so Norvir is better used as a booster for other protease inhibitors. Norvir works by inhibiting an enzyme called Cytochrome P450-3A4, found in the liver.

HNTB Holdings has been assigned a patent for a “system and method for collecting and modeling object simulation data”

The patent claims a method and system for collecting and modeling object simulation data. The system also includes a means for presenting the data in graphical form. In addition, the method uses a database with geographic data to create a geographically accurate representation of the traffic environment. The system also includes a route selector.

An exemplary system is shown in FIG. 5, which consists of multiple applications that collect real-time simulation data and convert it into 3-dimensional representations. Each extraction application 508 is in communication with a simulation application 505. The system also includes a virtual reality interface 515 (which may be located on a remote computer 520).

The system also includes an object simulation model associated with a portion of a network representation, such as a node or link. The network representation may be a microscopic, mesoscopic, or macroscopically modeled network.

The system and method of the invention allow for spatial analysis of traffic flow on a large road network. The system also integrates geographic information systems with traffic simulation processes to determine traffic loads and patterns. It also enables the import of data such as travel demand, road network, and survey data. In addition, it includes multiple traffic simulation models with varying levels of granularity.

In one embodiment, the system and method 600 refers to receiving data from a database containing information about the location of moving objects. This data may include the location of traffic signals, vehicles, people, baggage, and military personnel.
