Title: An intelligent agent for the dynamic generation/retrieval of descriptive/display software modules
Inventor: MAYORGA RENE V
IPC: G05B13/02
Filed: 1997-06-30
Abstract: Here a novel Intelligent Agent is devised for the dynamic generation/retrieval of descriptive/display (multi-media units, web pages, graphic user interfaces (GUIs), cd-rom information, etc.) computer software modules. The overall software system is based on the proper integration of an Active Input Interface with an Intelligent Inference System and an Output Interface. The Intelligent Inference System is the core of the Intelligent Agent and consists of an Expert System, a Fuzzy Logic Inference System, and an Adaptive Neural Network to constitute an appropriate co-active adaptive neuro fuzzy inference system. The Intelligent Agent is devised such that a human being will interact with a user friendly Active Input Interface by answering questions of a crisp/fuzzy nature, and/or selecting options via a crisp/fuzzy input icon. The software system will then instantaneously generate via the Output Interface a dynamic descriptive module. This module can be instantaneously accessed by the user and be retrieved to be displayed as preferred at any time; and/or also be instantaneously retrieved to be displayed as preferred by other users in other (which can be distant) server sites at any time.

Patent CA-2216918-A1 (CA)
Title: Biological tissue stimulation by optical energy
Inventor: BELLINGER GARY J
IPC: A61N5/06
Filed: 1995-03-31
Abstract: Biological tissue of a living subject is irradiated with optical energy at a wavelength and at a power dissipation level to cause the amount of optical energy absorbed and converted to heat in the tissue to be within a range bounded by a minimum absorption rate sufficent to elevate the average temperature of the irradiated tissue to a level above the basal body temperature, but which is less than the absorption rate at which tissue is converted into a collagenous substance. According to this method, a therapeutic, warming effect is produced within the irradiated tissue, but without causing tissue damage by thermal overheating. The method of using a low level reactive laser system from 100 milliwatts to 800 milliwatts in either a pulsed or continuous mode with optical energy produced by a Nd:YAG  laser at a fundamental wavelength of 1,064 nanometers has been found to reduce pain in soft tissues, reduce inflammation and enhance the healing of tissue by stimulation of microcirculation without subjecting the living tissue to damaging thermal effects.

Title: Seed-blanket reactors
Inventor: RADKOWSKY ALVIN
IPC: G21C1/00
Filed: 1996-08-14
Abstract: Seed-blanket type nuclear reactor cores (10, 100) are employed to burn thorium fuel with conventional reactor fuels, including nonproliferative enriched uranium, and weapons or reactor grade plutonium. In a first embodiment, the core (10) is completely nonproliferative in that neither the reactor fuel, nor the generated waste material, can be used to manufacture nuclear weapons. In a second embodiment of the invention, the core (100) is employed to burn large amounts of weapons grade plutonium with the thorium, and provides a convenient mechanism by which stockpiled weapons grade plutonium can be destroyed and converted into electrical energy. The cores of both embodiments are comprises of a plurality of seed-blanket units (12, 102) which have centrally located seed regions (18, 104) that are surrounded by annular blanket regions (20, 106). The seed regions contain the uranium or plutonium fuel rods (22, 110), while the blanket regions contain thorium fuel rods (26, 118). The moderator/fuel volume ratios and relative sizes of the seed and blanket regions are optimized so that neither embodiment generates waste materials that can be employed for manufacturing nuclear weapons. A novel refueling scheme is also employed with the first embodiment to maximize seed fuel utilization, and further ensure that the spent fuel cannot be employed for manufacturing nuclear weapons.

IPC: H04H20/82
Filed: 1996-07-25
Abstract: A method and apparatus for carrying out synchronous co-division multiple access (SCDMA) communication of multiple channels of digital data over a shared transmission media (1162). The system includes modems at remote units (1164) and a central unit (1160) to receive time division multiplexed digital data arranged into timeslots or channels and uses orthogonal codes to encode each channel of multiple data and spread the energy of each channel data over a frame of data transmitted in a code domain. Frames are synchronized as between remote (1164) and central units (1160) using a ranging scheme which is also useful in any other system transmitting data by frames in a distributed system where synchronizing the frames as between all units regardless of differences in propagation delays is necessary. Each frame in the SCDMA modulation scheme includes a gap or guardband containing no other data.
