Patent number: 11054362Abstract: A system and method adapted to have high sensitivity to the formation of biofilm by mixed community bacteria in fluids. The system enhances corrosion imbalance by differentiating conditions between metal sensor elements immersed in the liquid being monitored. The liquid may be diverted to and flowed through a sample chamber where adjacent sensor elements may reside in different flow velocity or temperature regions. The differentiated conditions allow for different film formation on one of the sensor elements relative to the other, and also more quickly than in the main system from which the sampled liquid has been diverted. The differentiated formation allows the use of measurement of polarization current between the metal sensors to produce data with superior resolution relative to prior methods. The speed of film formation promoted by the differentiated conditions allows for determination of risk of film formation in the main system prior to that film's formation in the main system.Type: GrantFiled: July 21, 2017Date of Patent: July 6, 2021Inventor: David Robert Howland

Patent number: 10793821Abstract: The invention provides a technology for promptly determining bacterial identification or an antimicrobial susceptibility testing. In the invention, first, a state where the bacteria are divided is monitored by performing microscopic observation with respect to the shape or the number of bacteria in each of wells of a culture plate for bacterial identification culture or the antimicrobial susceptibility testing. In addition, the shape, the number or the area of the bacteria are interpreted from the image obtained by the microscopic observation whether or not the bacteria proliferate at a stage from an induction phase to a logarithmic phase, and the time-dependent changes thereof are made into a graph. From the graph, it is determined whether or not the bacteria proliferate for each measurement, the determination results are displayed on the screen, and accordingly, the result of the antimicrobial susceptibility is provided every time when the measurement is performed (FIG. 12).Type: GrantFiled: January 22, 2016Date of Patent: October 6, 2020Assignee: HITACHI HIGH-TECH CORPORATIONInventors: Chihiro Uematsu, Muneo Maeshima
