  • Methods and apparatus for detecting particles entrained in fluids
    Patent number: 9541475
    Abstract: Apparatus and methods for size-specific detection of particles entrained in fluids are provided. A particle size selector separates particles entrained in a sample fluid stream using a curved channel. Shroud fluid streams are interposed between the sample fluid stream and walls of the channel. Centrifugal forces arising from fluid flow through the curved channel separate differently-sized particles into different transverse sections of the channel. A detector downstream from the particle size selector specifically detects particles in one or more transverse sections of the channel.
    Type: Grant
    Filed: October 28, 2011
    Date of Patent: January 10, 2017
    Assignee: The University of British Columbia
    Inventors: Winnie Chu-Hui Chu, Allison Schaap, Boris Stoeber

  • Monitoring system and monitoring method
    Patent number: 6977585
    Abstract: To provide a monitoring system and method that allows customization of a monitoring system and method according to a user's instruction, thereby achieving a higher flexibility in configuring the monitoring scheme. The monitoring system comprises a user system and a security server. The user system includes a capture unit, an input unit, a sensor, an imaging unit and a home server. The home server accepts the user's instructions and configure monitoring program realized by the home server. The user may specify logical connections between imaging unit and sensor, notification rule when the alarm is occurred.
