Title: Externally guided er damper
Inventor: NIAURA WILLIAM S
IPC: F16F9/53
Filed: 2000-06-15
Abstract: A vibration damping device is mounted between two spaced portions of a vehicle for absorbing road forces exerted on the vehicle. A cylindrical housing forms an internal piston chamber and is connected at one end to one portion of the vehicle, with an outer end of the rod of a piston which is slidably mounted within the piston chamber, being connected to another portion of the vehicle. A fluid transfer duct is formed between the housing and piston and provides communication between fluid subchambers formed on opposite sides of the piston within the piston chamber. An electrode is attached to either the housing or piston for applying a voltage across the duct to affect the rheological response of an electrorheological (ER) fluid flowing therethrough to provide a controllable mechanism to modify the damping force characteristics of the device. Each end of the piston rod is slidably supported by a slide bushing assembly which is mounted within an end of the housing. The slide bushing assemblies are separated from the ER fluid contained in the fluid chamber by elastomeric seals to reduce bushing wear and deterioration of the ER fluid.

Title: The process of identification of mutations that control the ability of viruses to replicate and cause disease and the application of these mutations to viral diagnosis and antiviral therapy
Inventor: BROWN EARL G
IPC: C12Q1/70
Filed: 2001-03-09
Abstract: There is currently little understanding of the genetic basis for virulence or growth control in viruses. The invention provides methods of identifying mutations that control viral virulence and growth as well as the application of the detection of these mutations to diagnostic and therapeutic purposes. This patent identifies a process of selecting viral variants that accumulate biologically relevant mutations. The process involves the serial culturing of large populations of virus under conditions of restricted replication in this instance in the lung of mice but can include other types of tissues, that selects viruses with mutations that both increase replication and virulence.  These mutations also involve regions of proteins that are in involved in controlling aspects of specific viral protein and RNA interactions. These regions define targets for antiviral drug intervention.
