  • Publication number: 20030126049
    Abstract: Potential risk exposures of an organization's activities in new and evolving areas where historical data is not available, are assessed using a programmed technique and expert algorithm. A questionnaire prompts for answers that must be selected from a limited quantifiable set, or alternatively will default to a high risk assessment. The answers are scored using an algorithm that computes potential risk levels using stored data and expert rules. A report is generated containing information identifying potential risk levels and preferably contains recommendations selected as a function of the answers or the assessed risks. The responses and report are stored to be used for comparative purposes in future assessments. The technique is useful in assessing risks, although the new and evolving activity may not be well understood or characterized by a data store of experience in similar claims.

  • Patent number: 5818400
    Abstract: A display device that includes a display medium having a planar display area over which an image is generated, a first and second optical point beam each directed in the display medium coplanar with the planar display area, and beam controllers that scan each of the optical point beams to selectively interfere in the display area within a region defined by the intersection of the optical point beams to produce an intensity in the region that has enhanced visibility relative to the individual optical beams propagating in the display medium outside of the region. The beam controller may be an elongated reflector having a reflecting surface upon which a linear array of liquid crystal modulators are controlled to selectively transmit segments of a linear beam incident on the linear array, in order to provide the optical beam by selectively reflecting segments of the linear optical beam into the display medium.
