  • Patent number: 9897528
    Abstract: A particulate detection system (1) for detecting the quantity of particulates S in a gas under measurement EG includes first heater energization means S2 to S3, current convergence determination means S4 to S5, S7 to S8, second heater energization means S6, and detection start means S10. S2 to S3 performs low-temperature energization of heater (78) for a predetermined period after operation of ion source (11) is started by ion source drive circuit (210) such that gaseous discharge current Id becomes equal to a predetermined target current It. S4 to S5, S7 to S8 determines, after elapse of the predetermined period, whether or not Id has converged to an allowable range IR. When S4 to S5 determines that Id has not yet converged, S6 performs high-temperature energization of the heater (78) until Id converges. Then, S10 starts detection of particulates S using signal Is detected by a detection circuit (230).

  • Patent number: 9880138
    Abstract: Many diseases are difficult to diagnose or present with no symptoms that would suggest that medical diagnosis is needed until significant bodily damage has occurred. We disclose a medical toilet that may be used to diagnose disease. The toilet comprises a conduit through which volatile organic compounds travel from the toilet bowl to the environment outside the toilet. The invention includes methods that comprise the steps of training an animal to identify the scent of bodily waste collected from a user that is afflicted with a defined disease. A user's bodily waste is deposited into the medical toilet and the animal is then exposed to the volatile organic compounds traveling through the conduit on the medical toilet. The animal performs an act that signals that the animal has perceived the smell associated with the disease. Thus, we disclose a novel device for diagnosing disease and methods of user thereof.

  • Patent number: 9857343
    Abstract: A gas sensor includes a protective cover having a resin cylindrical cover portion at a rear end thereof, that can be airtightly attached to an attachment hole, and that can prevent a decrease in quality and a molding defect. A plurality of vertical ribs, which extend substantially parallel to an axis of a cylindrical cover portion, are formed on an outer peripheral surface of the cylindrical cover portion so that protrusions and recesses are provided in a circumferential direction. Due to the presence of the vertical ribs, as compared with an existing cylindrical cover portion that has a smooth outer peripheral surface without the vertical ribs, defects of the outer peripheral surface are not likely to occur in a molding process. Moreover, because slipping is not likely to occur when an operator holds and twists the cylindrical cover portion with his/her fingers, an attachment operation can be smoothly performed.

  • Patent number: 9851277
    Abstract: Mechanical, electronic, algorithmic, and computer network facets are combined to create a highly integrated advanced gas sensor. A sensor is integrated into switchgear housings. These sensors integrated into high voltage switchgear products, deployed by electric utility end users in replacement and expansion cycles, function to detect and mitigate atmospheric pollution caused by leaking SF6. As its associated gas insulated tank is charged with 10 to 350 lbs. of SF6, each gas sensor monitors its local cache of gas, accurately sensing and computing fractional percentage losses (emissions) and gains (maintenance replacement) in SF6 mass, storing data in onboard data logs, and communicating data when triggered by detection events or in response to remote requests over a hierarchical communications network, a process that continues without labor until a fractional leak is automatically detected and reported creating the opportunity for early leak mitigation.
