Abstract: An apparatus and method for performing data entry with light based touch screen displays and that is capable of implementing the functions of inking, pressure sensitive data entries, the rate of descent and angle of entry of the pen or stylus, the ability to rotate objects, double-clicking objects, fast clicking, etc. The apparatus and method includes a touch screen and a stylus having a tip that compresses depending on the amount of force is applied to the stylus when placed in contact with the touch screen during a data entry operation. A processor is provided to generate a display on the touch screen that traces the movements of the stylus on the touch screen. To implement the inking function, the processor is configured to extrapolate the relative thickness of the display generated on the touch screen to be commensurate with the amount of compression of the tip caused by the amount of writing force applied to the stylus. The amount of compression of the tip also enables pressure sensitive data entries.

Abstract: A folded optical element waveguide that allows a minimum width bezel to be used around the perimeter of a light-based touch screen display. The apparatus and method includes a touch screen and a waveguide substrate provided adjacent the touch screen. The waveguide substrate includes a plurality of waveguides and a plurality of optical elements provided adjacent the touch screen. The waveguides include an internally reflective surface to reflect light perpendicular to the surface of the touch screen. The emitting and detecting waveguides are thus folded and provided around the side edges of the display. As a result, the width of the bezel around the display can be minimized.

Abstract: Flexible optical waveguide substrates that can be used with touch screen displays. The waveguide substrates include a flexible base material. A first optical layer having a first index of refraction value is formed on the flexible base material. A second optical layer is then formed on the first optical layer, the second optical layer being patterned to form a plurality of optical elements and waveguides respectively. The second optical layer also has a second index of refraction value higher than the first index of refraction value. Lastly, a third optical layer is formed on the second optical layer. The third optical layer has a third index of refraction value lower than the second index of refraction value. The high N second layer is therefore sandwiched between the lower N first and third layers, creating an internally reflective surface wherever the high N and low N materials are in contact. The base material and first, second and third optical layers thus form a flexible waveguide substrate.

Abstract: A coffee dosing apparatus provided with a holder for coffee powder and a dosing mechanism, the dosing mechanism being provided with a dosing chamber, which is bounded at a lower side by a bottom wall with a discharge opening, and which is bounded at an upper side by an upper wall with a feed opening, a rotatable dosing element bounding portion spaces being arranged in the dosing chamber, a driving element being connected with the dosing element, wherein between the driving element and the dosing element a coupling is provided, which is such that the dosing element is rotatable in limited steps, at the end of a limited step a mentioned portion space being located above the discharge opening, and a next limited step being startable only after the preceding limited step has been rounded off completely.

Abstract: The process is a continuous process and comprises bringing together streams comprising a triglyceride oil and a catalyst solution of water, sodium hydroxide and glycerine respectively, homogenizing the mixture, reducing its water content, and interesterifying. Preferably the homogenization and drying steps take place consecutively and are combined and are performed by passage through a spray drying nozzle. The efficiency of the homogenization and drying steps allows the interesterifying step to take place in about 4 minutes and thus permit operation of the process in a continuous manner.
