摘要： Disclosed herein are methods and systems for presenting product stock information. In some implementations, an image of a portion of a retail store is received from a camera and analyzed to divide the image into macroblocks. Each of the macroblocks can be associated with one or more product facings associated with products placed on a shelf in the retail store. A color from the macroblock is optionally identified and compared to a product color or a shelf color to determine a stock level of the product. In some implementations, a reporting module presents the stock level in a graphical user interface to a user.

摘要： This invention relates to a liquid crystal device with grey scale. The invention uses dither, either spatial or temporal. For spatial dither the invention arranges so that at least one bit of dither is not a multiple of the size of a smaller bit of dither—in other words there is a fractional weighting. The two bits of dither have the same number of addressable transmission levels and the weighting sacrifices some linearity in exchange for reduction of manufacturing tolerances for the smaller bit. For temporal dither the invention relates to fractional weighting of the duration of the sub-frames.
摘要翻译：本发明涉及一种具有灰度级的液晶装置。本发明使用空间或时间的抖动。对于空间抖动本发明进行布置，使得抖动的至少一个比特不是较小比特抖动的大小的倍数 - 换句话说，存在分数加权。抖动的两个位具有相同数量的可寻址传输电平，并且加权牺牲了一些线性，以换取较小位的制造公差的减小。对于时间抖动，本发明涉及子帧的持续时间的分数加权。

摘要： This invention relates to a photopolymer mixture capable of use for a liquid crystal alignment layer and to an alignment layer formed from such a photopolymer mixture. The mixture comprises at least two polymerisable materials which are blended together in proportion so as to give a predetermined, preferably low, surface energy. A low surface energy, e.g. less than 4×10−2 N/m can result in an alignment layer which imparts a particular orientation to liquid crystal molecules with out requiring any post cure treatments. The polymerisable materials may be monomers, oligomers or diluents that form long chain molecules when cured and the mixture may contain additives to lower the overall surface energy.

摘要： A method of addressing bistable nematic liquid crystal devices is provided. The method is suitable for implementation using commercially available STN drivers. The method involves applying one of at least two data waveforms simultaneously to each column electrode whilst an active row waveform is applied to an active row and a non active row waveform is applied to all other rows. The resultant waveform at the pixels on the active row comprises a blanking portion sufficient to cause the liquid crystal material to blank, irrespective of which data waveform is applied, immediately followed by a discriminating portion which allows for selective latching depending on the data waveform applied.

摘要： Liquid crystal devices are described that exhibit bistable, tri-stable or other multistable operation. The stable liquid crystal configurations are attained using a surface alignment grating (144) on the internal surface of at least one cell wall (142). The surface profile of the surface alignment grating comprises three or more defect sites per grating period and permit the liquid crystal molecules to adopt any one of two or more stable pretilt angles in the same azimuthal plane. Application of a suitable voltage causes the liquid crystal material to switch between the stable configurations.

摘要： A bistable nematic liquid crystal device is addressed by application of a row waveform to successive row electrodes of an x, y matrix of pixels whilst one of two data waveforms are applied to each column electrode. The row waveform has a period of two or more time slots (ts), with two dc pulses of opposite amplitude for causing a switching to a dark state, and two dc pulses of opposite amplitude for causing a switching to a light state. The data waveforms have the same period as the strobe with dc pulses of opposite amplitude and combine with the strobe pulses to switch the device. The device can be addressed in two field periods, one field switching to a dark state, the other field switching to a light state. Alternatively, the device can be blanked to the dark state then selectively switched to the light state. When blanking is used, the row waveform has blanking de pulses placed a short time before selective switching to reduce overall addressing time. Zero voltage pulses may be used within the two or more time slot period of the strobe and data waveforms; these reduce rms. voltages appearing at the pixels and enhance contrast ratio.
