Patent CA-2166758-A1 (CA)
Inventor: KELLEY PATRICK D
IPC: A61K33/30
Filed: 1996-01-08
Abstract: This invention relates to topical lubricants that can be spread  across  the  surfaces  of  the  genitals  during  sexual intercourse,  to reduce the risk of  infection by the human immunodeficiency virus (HIV, the virus that causes AIDS). The anti-HIV lubricants of this invention contain a non-toxic, non-irritating, water-soluble zinc salt that can directly inhibit the infectivity of HIV virus particles and reduce the risk of infection even in users who do not suffer from genital lesions caused by other diseases, such as genital herpes or syphilis. Suitable zinc salts include zinc acetate, zinc propionate, and other non-irritating water-soluble organic salts of zinc that readily dissociate into ionic form when dissolved in water (dissociation levels preferably should be equal to or higher than the dissociation rate of zinc gluconate in water). Free zinc,  in  cationic  form  (Zn++),  is  believed  to  reduce  the infectivity of HIV virus particles by forming crosslinking bonds with cysteine or histidine residues in the gp120 protein of HIV. Inside a vaginal cavity, these crosslinking bonds can cause HIV particles to bind in a more or less random manner to other viral particles, to proteins in vaginal fluids, and to proteins on the surfaces of epidermal or epithelial cells that will soon be sloughed off  from the genital  surfaces.  This cross-linking activity eliminates or reduces the infectivity of HIV particles. A two-step incubation assay is also disclosed for evaluating candidate anti-HIV agents for use in topical lubricants. A brief first incubation step models agent-virus interactions inside a vagina,  after  intercourse. The agent/virus mixture  is then dliuted to suitable levels before HIV-susceptible lymphocytes are added and incubated in a second, much longer incubation step.

Abstract: At a post stage of an amplifying optical fiber, such a means is provided that detects a level of light having a center wavelength of the amplified signal light, and also a level of light having a wavelength different from that of this center wavelength, and further another means is provided which compares the level of the light having these wavelengths, and controls an output of a pumping light source based on this comparison result. To detect the intensity of the light having these two wavelengths, two light branching devices, and light receiving devices are arranged via the respective light band-pass filters for passing therethrough the light having the above-described wavelengths at the post stage of the amplifying optical fiber. When the light intensity ratio of both the light having the wavelengths is larger than a preset value, the output of the pumping light source is maintained.          Conversely, when this light intensity ratio is smaller than this preset value, the output of the pumping light source is interrupted by assuming that the input signal light is interrupted. The adverse influences caused by the light surge can be avoided without increasing the noise figure.

Patent CA-2181398-A1 (CA)
Inventor: PAPADOPOULOS HARALABOS C
IPC: H04W92/00
Filed: 1996-07-17
Abstract: A method and system for reducing co-channel interference (CCI) in multiple access communication by providing complete or partial cancellation of a mixed CCI interfering signal in a system base station. An exemplary system includes first and second base stations communicating with users in first and second cells, respectively. The first base station transmits a downlink signal to a user in the first cell. The downlink signal is also a mixed CCI interfering signal in that it interferes with reception of an uplink signal in the second base station. A cancellation signal representative of the interfering signal is supplied along a transmission path from the first base station to the second base station. The second base station utilizes the cancellation signal to reduce the effect of the interfering signal on a received composite signal by, for example, combining the cancellation signal or a suitably processed version thereof with the received composite signal. Other aspects of the invention involve reducing mixed CCI by providing non-uniform quality of service, by dropping potentially interfering packets, or by full or partial circular interleaving of packet slot assignments.

Title: Image processing method, image processor, and pseudo-experience device
Inventor: GODEN TAKESHI
IPC: A63F13/55
Filed: 1996-06-27
Abstract: A system according to this invention comprises an image display means 300, a central processing unit 102, memories 103 - 108, a program processing section 100 which executes a game program which moves a moving object in a virtual three- dimensional space in which three-dimensional objects are arranged, and an operation section 200 which accepts speed data about the moving objects in the virtual three- dimensional space and outputs the data to the program processing unit. The operation section 200 outputs moving- object speed data to a perspective conversion unit 110. The perspective conversion unit 110 varies the distance between a viewpoint and a projection screen according to the relative speed of the moving object. As the effective visual area on the projection screen decreases, the range of the virtual three-dimensional space displayed in the effective visual area increases. This makes the field view angle of the projection screen variable according to the speed of the moving object.
