Abstract: A cartridge acting as a dispenser for liquid treatments of a human or animal body is U shaped or hoop shape. The cartridge has a container containing a liquid treatment which when required to be dispensed is ejected through one or more nozzles projecting through the wall of the cartridge into the centre of the U or of the hoop. A base is provided for cartridges, the base controlling timing and quantity of treatments.

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.

Abstract: The present invention relates to an apparatus for coating carrier particles with guest particles. The apparatus comprises a cylindrical processing vessel rotatable about its axis and having solid walls defining a chamber for receiving the particles, and a hollow shaft extending within the chamber at least partly along the axis of the cylindrical processing vessel, the hollow shaft defining a gas flow path connected to a gas inlet. The hollow shaft comprises one or more axially-extending slots or one or more axially-extending rows of apertures allowing fluid communication between the gas flow path and the chamber.

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.

Abstract: An impact protection apparatus has a body portion formed of a first resilient material and a number of members protruding radially outward from the body portion. The members are formed of a second resilient material which is the same as or different from the first resilient material. The impact protection apparatus has an adhesive material or a mechanical fastener disposed about the body portion and/or the members. The apparatus may be affixed to a surface.
