  • Publication number: 20230160808
    Abstract: A microfluidic chip configuration wherein injection occurs in an upwards vertical direction, and fluid vessels are located below the chip in order to minimize particle settling before and at the analysis portion of the chip's channels. The input and fluid flow up through the bottom of the chip, in one aspect using a manifold, which avoids orthogonal re-orientation of fluid dynamics. The contents of the vial are located below the chip and pumped upwards and vertically directly into the first channel of the chip. A long channel extends from the bottom of the chip to near the top of the chip. Then the channel takes a short horizontal turn that nearly negates any influence of cell settling due to gravity and zero flow velocity at the walls. The fluid is pumped up to a horizontal analysis portion that is the highest channel/fluidic point in the chip and thus close to the top of the chip, which results in clearer imaging.

  • Patent number: 7616293
    Abstract: A system of lasers and detectors to detect the presence of objects and determine their speed is disclosed. The system comprises of a pair of lasers and a pair of detectors focused through a single lens or a pair of lenses. An electronic board that accompanies the lasers and detectors is used to provide the logic and decision making mechanism. Data collected and processed by the system yields such information as whether an object is present, whether the object is stationary or is moving, and subsequent speed information. The described system is also capable of providing additional information concerning the characteristics of the moving object such as its profile and length, and indication of a traffic violation.
