Patent CA-2335759-A1 (CA)
Inventor: BROWN PAUL M
IPC: G21F9/00
Filed: 1999-06-25
Abstract: An apparatus and method for treating long-lived radioisotopes and transmuting them into short-lived radioisotopes through applied nuclear physics. Nuclear reactions, specifically of the (.gamma., n) type, also known as photodisintegration, are utilized to accomplish this transmutation from a radioisotope of given atomic mass to that of lower atomic mass. A radioactive element (1) is irradiated by high-energy photons, preferably in the form of gamma rays. The gamma rays are absorbed by the nucleus of the radioactive element placing it in an excited state. Upon relaxation from the excited state, the nucleus ejects a neutron, thereby transmuting the element to an isotope of lower atomic mass and shorter half-life.

Abstract: A method for interacting with a user when establishing viewing preferences for a television decoder enables a user to quickly set his or her viewing preferences by interacting with a graphical display. The broadcast ratings system is converted to a numerical or ordered range so that the ratings are placed in a progressive order from least objectionable to most objectionable. One possible implementation is to associate a numerical value with each rating and then order the ratings in accordance with the numerical sequence. Once the ratings are ordered, the ratings are displayed to the user in a graphical fashion so that the user can select a position on the graph that represents the user's viewing preferences without necessarily requiring the user to understand the underlying implications of the ratings system.
