Abstract: A fire alarm device and method capable of informing people with visual and hearing difficulties of occurrence of fire. A fire detection means (1) detecting the occurrence of fire is connected to an emission control means (4). A smell emitting means (9) activated by the emission control means 4 is also connected to the emission control means (4). The fire detection means (1) activates the emission control means (4) when detecting the occurrence of fire. The emission control means (4) is provided with a smell condition-setting means so as to set starting time for continuously-emitted smell, and to set emission periods, emission intervals and emission concentrations for intermittently-emitted smell. The smell emitting means (9) will be activated in accordance with the conditions set by the smell condition-setting means.

Abstract: An object of the present invention is to provide a diagnostic sensor and a diagnostic system capable of easily detecting abnormality in a human body by a simple apparatus without using a conventional testing method of removing a part of tissues and/or taking blood, which gives pain to the patient, and examining the part of tissues and/or blood under a microscope for long time. A diagnostic sensor of the present invention includes: detecting means (2) for detecting any of various pathogens existing in a part of a living body and/or body fluid of the living body or a gas emitted from the living body, or an antigen (S) or ligand corresponding to abnormality or disease; and signal generating means (semiconductor integrated circuit 1) for generating a signal when the detecting means (2) detects any of the pathogens, antigen (S), or ligand.

Abstract: An apparatus and method for generating a desired smell by processing smell information through a combination of a computer system and a perfume generating means. In order to generate a desired smell under control of a computer, preset perfume information concerning a smell classification table, kinds of preset perfume corresponding to the items of smell in the smell classification table, the amount of smell to be generated and the variation with time of the amount is registered, the item of a specific smell is selected from the smell classification table, and relevant pieces of the preset perfume information corresponding to the item of the specific smell is extracted. A deodorant may be combined or various smells may be combined with an image.
