  • Electro-optic displays, and materials and methods for production thereof
    Patent number: 7733554
    Abstract: A front plane laminate (see U.S. Pat. No. 6,982,178) is produced by forming a sub-assembly comprising a lamination adhesive layer and an electro-optic layer, forming an aperture through the sub-assembly, and securing a light-transmissive electrode layer to the sub-assembly so that the electrode layer extends across the aperture. Alternatively, formation of the aperture is omitted, and the electrode layer has a tab portion extending beyond the edges of the lamination adhesive and electro-optic layers. When a front plane laminate is secured to a backplane to form an electro-optic display, a stiffening layer may be attached to either part to increase its stiffness, then removed after the lamination. An electro-optic display or front plane laminate may use an adhesive layer comprising separate layers of cross-linked and non-cross-linked adhesive.

  • Calculating a doppler compensation value for a loudspeaker signal in a wavefield synthesis system
    Patent number: 7734362
    Abstract: For reducing Doppler artifacts in the wave-field synthesis due to delay changes from one time to a second time, first, the delay for the first time and the delay for the second time are determined. Then, a value of an audio signal delayed by the first delay for the current time and the value for the audio signal delayed by the second delay for the current time are determined. Then, the first value is weighted by a first weighting factor and a second value is averaged with a second weighting factor, whereupon the two weighted values are added up to obtain a discrete value for the current time of the component in a loudspeaker signal for a loudspeaker based on a virtual source. Thus, by knowing a delay present at a later time, panning is obtained from a delay to a subsequent delay, which reduces undesired Doppler artifacts.

  • Revolving door control system
    Patent number: 7733043
    Abstract: In a method and system for controlling a revolving door that has a plurality of chambers defined by wings of a revolver, at least one imaging sensor is provided for acquiring images of a first area where the plurality of chambers rotatably pass by or through. A drive causes the revolver to rotate in a first direction from a first position where a user can enter a first chamber via the first opening. Images are acquired by the one imaging sensor and signals are acquired from a position sensor that is operative for outputting signals indicative of the angular position of the revolver. Based on the signals acquired from the position sensor, each imaging sensor or its output is disabled and/or each image acquired by each imaging sensor is ignored when each door wing is in field-of-view of the imaging sensor.
