  • Patent number: 7877265
    Abstract: A system and method for automated customer feedback allows for automatically collecting and analyzing customer feedback data regarding customer satisfaction and customer task completion with respect to self-service applications and live agents. When contacting a customer service center, customers provide one or more customer tasks. The customers are routed within the customer service center based on the customer task and/or one or more customer characteristics. While interacting with the customer service center, the customers are automatically asked one or more specific survey questions relating to the customers' interaction with the customer service center and the customers' satisfaction levels. The customers provide one or more survey responses to the survey questions. The survey responses are recorded and analyzed in order to modify and update the customer service center and the survey questions in order to increase customer satisfaction and increase customer task completion.

  • Patent number: 7697098
    Abstract: It is an object of the present invention to suppress light leakage in a dark state which is generated by rubbing treatment. A liquid crystal material containing an ultraviolet curable liquid crystalline monomer at a concentration of more than 0 wt % and not more than 1.0 wt % is used for a liquid crystal layer, and the liquid crystal layer is irradiated with ultraviolet rays. By applying such a liquid crystal layer to a liquid crystal display device, light leakage in a dark state can be suppressed, and the black display can be improved. Therefore, a liquid crystal display device with an excellent contrast and high display quality can be obtained.

  • Patent number: 7583333
    Abstract: There is described a process for the production of LCDs, in particular PDLCDs, preferably in a roll-to-roll process, wherein in a first process step a first contact layer (12) and a first electrode layer (14) spaced therefrom is applied to a base carrier (10). A first and a second delimitation layer (18, 20) is then applied to the base carrier (10). Thereafter a functional layer (26) comprising a PDLCD mixture provided in a porous support matrix is applied between the first and second delimitation layers (18 and 20). A protective layer (28) is then applied to the functional layer (26) between the first and second delimitation layers (18 and 20) and finally there is applied to the protective layer (28) a second electrode layer (30) which is contacted with the first contact layer (12).
