Title: Traitement d'infections par papillomavirus
Inventor: ZHOU JIAN DI
IPC: A61P31/20
Filed: 1999-12-13
Abstract: Cette invention se rapporte au traitement d'infections par papillomavirus, et concerne un procédé de traitement d'une infection existante par papillomavirus (PV). Ce procédé consiste à administrer, à un patient souffrant d'une infection par PV, des particules vériformes (VLP) par rapport au PV qui sont choisies dans le groupe comprenant des VLP L1 PV et des VLP L1/L2 PV. Une infection par PV se traduit en général par la présence de lésions épithéliales. L'infection principale que l'on peut ainsi traiter consiste en des verrues génitales causées par le PV humain 6 et le PV humain 11.

Title: Intrusion detection apparatus
Inventor: ARIAV ARIE
IPC: G08B13/16
Filed: 1989-10-06
Abstract: ABSTRACT         An  intrusion  detector  and  method  of  operating  the detector is disclosed.  The detector comprises a means including an antenna for transmitting spaced pulses of radiation energy of a given frequency throughout a region to be protected.  Means are also provided for receiving the radiation energy reflected from the protected region.  The reflected radiation energy is received between adjacent spaced transmitted pulses in the form of an AC analog signal at the given frequency, the peaks and valleys of which  signal vary  in  amplitude  with time.    Means  are  also provided for allocating a portion of the time occurring between transmitted pulses into a plurality of time segments, each of which segments is long enough to correspond to a plurality of cycles of the analog signal.   The detector further includes: means for integrating the plural cycles in each of the time segments to arrive at an integral value for each of the time segments;  means  for  converting  the  integral  values  into corresponding digital  values;  means  for  storing  the  digital values in memory; means for comparing the stored digital values obtained from the reflected energy from the first transmitted pulse with the corresponding digital values obtained from the reflected energy of an adjacent second transmitted pulse; means for   storing   the   absolute   differences   obtained   between corresponding integral values for each of the time segments; and, means  responsive  to  predetermined  changes  in  the  absolute differences  for  a predetermined  number of  time segments  for initiating an intrusion signal in the apparatus.
Patent CA-2002776-A1 (CA)
Inventor: CERUTTI PETER
IPC: C12Q1/686
Filed: 1989-11-10
Abstract: The invention relates to the direct detection of human papilomavirus DNA. The recently developed polymerase chain reaction was modified in order to improve the sensitivity and specificity. By choosing appropriate oligonucleotide primers (amplimers) and reaction temperatures, individual HPV genes from among the total cell DNA can be identified and amplified to an extent such that non-isotopic detection is possible. In addition, use of reverse transcription permits selective amplification of spliced mRNA and thus permits indication of premalignant or malignant conditions and/or lesions.

Title: Cooled blades for a gas turbine engine
Inventor: AUXIER THOMAS A
IPC: F01D5/18
Filed: 1990-01-12
Abstract: An internally cooled turbine blade for a gas turbine engine is modified at the leading and trailing edges to include a dynamic cool air flowing radial passageway with an inlet at the root and a discharge at the tip feeding a plurality of radially spaced film cooling holes in the airfoil surface.      Replenishment holes communicating with the serpentine passages radially spaced in the inner wall of the radial passage replenish the cooling air lost to the film cooling holes. The discharge orifice is sized to match the backflow margin to achieve a constant film hole coverage throughout the radial length.      Trip strips may be employed to augment the pressure drop distribution

Title: Method and apparatus for relating diagnostic information to specific computer instructions
Inventor: SITES RICHARD LEE
IPC: G06F12/0862
Filed: 1990-04-03
Abstract: METHOD AND APPARATUS FOR RELATING DIAGNOSTIC INFORMATION TO SPECIFIC       COMPUTER INSTRUCTIONS                   ABSTRACT OF THE DISCLOSURE      A computer system 10 employs an apparatus for controllably generating interrupts to the computer system processor 12 in order to correlate a significant event occurring within the computer system to the value stored within the program counter at the time of the significant event.  In this manner, the apparatus is useful for diagnosing the performance of the computer system.  The apparatus includes at least one pair of 16-bit binary counters 42, 44, each having inputs connected through respective multiplexers 50, 52 to a variety of significant event signals.  For example, the computer system 10 typically employs a cache where significant time can be wasted by repeated "misses" within the cache. By selecting the cache "miss" signal to be counted by the 16-bit binary counters 42, 44, a signal is generated approximately every 64,000 "misses."  The output of the counters 42, 44 are connected to high priority input ports 30, 32 of the processor 12 so as to generate an interrupt that will ordinarily be handled immediately upon the completion of the current instruction being executed.  The software interrupt routine retrieves the instantaneous value of the program counter and places that value within a buffer, which is subsequently written to a file in main memory.  Thus, at the completion of the program currently being executed, a file within the main memory contains an incidence chart of the particular instructions that generated the cache "misses."

IPC: H04L27/14
Filed: 1990-04-05
Abstract: Abstract of the Disclosure         RCA 84,675 A sampled data FM demodulator samples the FM signal at intervals of (2n.pi.+.pi./2) radians relative to the FM carrier. Pairs of samples Sn and Sn+1 are squared and multiplied together to generate sample values S2n, Sn+21 and SnSn+1. These sample values are lowpass filtered in a filter having a cutoff frequency which will substantially attenuate at least the second harmonic of the FM carrier. The lowpass filtered samples are then combined according to a given relation to generate demodulated output samples.
