Abstract: An odor generation alarm and a method for informing an unusual situation having a high attention attracting effect and a high degree of safety are provided. An odor generation alarm includes an odorant receptacle, a drive section, a detector and a circuit section which is a controller. The odorant receptacle contains an odorant. A concentration of the odorant in air at which a person can no longer tolerate a strength of smell is lower than a no observed effect concentration of the odorant. The drive section causes the odorant to be emitted from the odorant receptacle. The detector detects occurrence of an unusual situation, and outputs a detection signal. When the detection signal from the detector is inputted, the controller causes the drive section to emit the odorant in accordance with the detection signal.

Abstract: [Problem] To provide a disease diagnostic system capable of diagnosing with high accuracy whether a subject is afflicted with a disease, without inflicting pain on the subject. [Means for Resolution] The disease diagnostic system includes collecting means (5) for collecting a substance (e.g., aspiration, sweat, human waste or urine) emitting an odor (e.g., mouth odor, body odor or underarm odor) and storing the same therein, measuring means (10) for measuring whether an indicated substance indicative of the existence of a disease is contained in the odor-emitting substance stored in the collecting means (5), and control means (20) for processing a signal indicative of a result of measurement by the measuring means (10) to determine whether the subject (2) is being afflicted with a disease.

Abstract: The soil contamination detector and detection method are provided, the detector and the detection method can significantly simplify investigation and analysis of a contaminant without use of any large analyzer like a gas chromatograph. The soil contamination detector comprises a sensor (10) and a control mechanism (12). The sensor (10) is disposed in a region (4) as a contamination investigation object, for detecting odor (S) of a substance (M) contaminating soil (G). The control mechanism (12) compares the concentration (D) of the contaminant (M) detected by the sensor (10) with the tolerance limit concentration (Pd) of the contaminant (M) to determine the contamination.

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.

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 card hard to counterfeit it by reading information stored thereinside even if an electronic technique is abused, a card reader used to read such a card, and an authentication system using the card and the card reader. Therefore, in the present invention, fragrant materials (fragrant material chips 13) are placed at predetermined locations on a card surface on the side of contact with the card reader (card reader 2), and the surface on which the fragrant materials are placed in such a manner that a predetermined amount of fragrant-material molecules pass therethrough and are released, is covered so as to reach a flat surface.

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.
