Patent CA-2517771-A1 (CA)
Title: Magnetic resonance imaging interference immune device
Inventor: SIMPSON PAUL G III
IPC: G01R33/28
Filed: 2004-06-24
Abstract: A voltage compensation unit (410 or Figure 12) reduces the effects of induced voltages upon a device having a single wire line. The single wire line has balanced characteristic impedance. The voltage compensation unit includes a tunable compensation circuit (700 of Figure 20) connected to the wire line.  The tunable compensation circuit (700 of Figure 20) applies supplemental impedance to the wire line. The supplemental impedance causes the characteristic impedance of the wire line to become unbalanced, thereby reducing the effects of induced voltages caused by changing magnetic fields.

Title: Characterization of the earliest stages of the severe acute respiratory syndrome (sars) virus and uses thereof
Inventor: XU RUI HENG
IPC: C12N/
Filed: 2004-07-09
Abstract: Severe Acute Respiratory Syndrome ("SARS") is a human respiratory disease of recent origin, widespread infectivity, recurring incidence, and significant mortality. Although there is abundant evidence suggesting that the coronavirus responsible for the disease ("SARS-CoV") evolves during an outbreak, there is currently little data on the earliest strains of this coronavirus. The present invention is directed to the characterization of the genomic RNA sequences of these earliest SARS coronaviruses, to the identification of nucleotide positions within the SARS-CoV genomic RNA that are characteristic of the different evolutionary stages of the coronavirus, to kits based on these positions for use in diagnosis of the disease in patients, and for the development of vaccines to the disease based on the lowered virulence and contagiousness of these earliest strains of SARS-CoV.
