    Abstract: According to certain embodiments, a device for conditioning a flow of air includes a casing with an inlet and an outlet. The device has a flow conditioner disposed within the casing and concentrically aligned with the casing. The flow conditioner has a cylindrical portion and a domed end portion capping the cylindrical portion. The flow conditioner forms an annulus region between the flow conditioner and the casing. The flow conditioner also forms a mixing chamber interior to the flow conditioner. The flow conditioner also has a plurality of holes throughout the flow conditioner that are configured to permit air to pass from the inlet of the casing and the annulus into the mixing chamber. The device also has a flow straightener located at the outlet of the casing configured to straighten the airflow as it flows from the mixing chamber out of the device.

  • Publication number: 20200041377
    Abstract: A system (101) for examining lenses in a pair of glasses includes a tablet computer (112), a camera (128) mounted above the computer screen and a glasses mount (156) for holding a lens in a pair of glasses between the camera and the display screen. The camera (128) is operatively connected to the computer for storing and processing image data captured by the camera. In use, a test pattern is displayed on the screen below the camera and an image of the test pattern seen through a lens is captured by the camera. Image data is saved to the computer which processes the data to determine the power of the lens from the distortion to the test pattern caused by the lens. The results are displayed on another section of display screen. The camera mount (156) may be a plinth slidably positioned on the display screen.

  • Publication number: 20200041378
    Abstract: A test pattern (170) comprising a set of dots (174) which define a first ellipse (176) of best fit in which the major and minor axes R1, R2 are equal (i.e. a circle) is displayed on a plane surface and a digital image of the (usually distorted) test pattern seen through a lens is captured. A second ellipse of best fit joining the dots in the set is derived from the distorted test pattern in the image. Characteristics of the first and second ellipses are compared to determine the degree and nature of distortion to the test pattern, from which the power of the lens is calculated. The major and minor axes of the first and second ellipses may be compared. The test pattern can include a number of said sets of dots distributed over an area of the surface with each set being analysed to determine the optical parameters of the lens at multiple locations.
