Patent CA-2558977-A1 (CA)
Inventor: LUTZ ELEA BREWER
IPC: G09B19/00
Filed: 2006-09-07
Abstract: Disclosed are apparatuses and methods for teaching a person, particularly a child, to identify an object associated with a scent. The object can be any substance, material or thing, such as root beer, banana, vanilla or mint, having an identifiable scent. The apparatus includes at least one scented device, which is most preferably a playing card. Also included as part of the apparatus is indicia of the identity of the object. The indicia of identity may be located anywhere, such as on a sheet of paper, board or container, but is preferably located on the device at a position where it cannot be readily detected by someone smelling the device.  Optionally, the apparatus also includes indicia of one or more clues of the identity of the object and/or indicia of one or more things related to the object. One method by which a person uses the apparatus is by smelling the device and guessing the identity of the object. The guess is then compared to the indicia of identity of the object to determine if the guess is correct. One or more clues may be used to assist the user to guess the identity of the object. If the object is guessed correctly, the user may attempt to spell the name of the object, identify the appearance of the object, and/or guess things related to the object. Score may be kept based on correct or incorrect guesses and multiple users may engage in competitive play.

Inventor: YAO YHENGBIN
IPC: A61K39/395
Filed: 2005-05-26
Abstract: A method for preventing or treating mammalian diseases mediated by amphiregulin released from mast cells by administering an anti-amphiregulin antibody to a mammal. The antibody binds to the amphiregulin and prevents it from interacting with and activating mammalian cells that are involved in the pathogenesis of diseases. By preventing this binding and activation, the antibody prevents or treats any diseases mediated by amphiregulin released from the mast cells. Preferably, the method is used to prevent or treat allergic diseases, asthma, or fibrosis by reducing the affect of amphiregulin on the cells involved in such diseases.

This invention further provides a method for the prevention and treatment of diseases and conditions of the mouth, gums and teeth. The method for preventing and treating diseases and conditions of the mouth, teeth and gums is comprised of administering to a host in need thereof a therapeutically effective amount of a composition comprising a mixture of Free-B-Ring flavonoids and flavans synthesized and/or isolated from a single plant or multiple plants, preferably in the Scutellaria, Oroxylum, Acacia or Uncaria genus of plants and pharmaceutically and/or cosmetically acceptable carriers. Finally the present invention provides a method for the prevention and treatment of diseases and conditions of the mouth, teeth or gums, including but not limited to periodontal diseases, such as gingivitis, periodontitis, pulpitis, periodontal conditions caused by the physical implantation of oral dentures, trauma, injuries, bruxism, neoplastic and other degenerative processes; material alba, pellicles, dental plagues, calculus, and stains. Use of the composition described herein also affords the benefit of maintaining optimum saliva production and pH, minimizing bacterial growth, reducing the formation of pellicles and plague, inhibiting tooth decalcification and tooth caries (decay), promoting remineralization, which yields healthy gums, whitening teeth, maintaining healthy oral hygiene and reducing oral malodour (halitosis).

Abstract: Improvements in startup time for an electrochemical fuel cell system from freezing and sub-freezing temperatures are obtained by utilizing an insulated fuel cell stack in combination with an thermal control subsystem. Temperature of the insulated electrochemical fuel cell stack, as well as temperature of the ambient environment, are monitored and a heating fluid is heated by thermal transfer with the environment under appropriate thermal conditions.  The heated fluid is then passed to the insulated fuel cell in order to increase the temperature of the same, typically to a temperature at or near the temperature of the ambient environment. In this manner, ambient heat from the environment is utilized to increase the temperature of the insulated fuel cell stack, thus improving conditions for subsequent cold start of the insulated fuel cell stack.
