摘要： A position management system manages position information of a second apparatus which carries out wireless communications with a first apparatus that is installed indoors. The position management system determines radio field intensity of radio waves of the wireless communications that are received from the first apparatus when movement of the second apparatus is detected, acquires first position information that indicates a position of the second apparatus estimated based on the determined radio field intensity of the radio waves, and stores the acquired first position information associated with time information.

摘要： A position management system includes a first receiving unit configured to receive a radio wave according to a predetermined wireless communication standard from a first device when the movement of a second device is detected; a second receiving unit configured to receive second position information including latitude and longitude information from an IMES transmitting device when the movement of the second device is detected; and an acquiring unit configured to measure an intensity of the received radio wave, estimate a position of the second device based on the intensity, and acquire first position information indicating the estimated position. The second receiving unit receives a radio wave from GPS when the second device moves outdoors where communication with the IMES transmitting device is not possible, and sets latitude and longitude information, which is measured based on the radio wave received from the GPS, as the second position information.

摘要： A phase compensator having a biaxial birefringent component (40) is fabricated by oblique deposition of an inorganic material on a base plate (69). A polar angle of an evaporation path of the inorganic material is controlled in a predetermined angular range to a surface normal of the base plate (69). In the oblique deposition process, the base plate (69) is oscillated in a horizontal direction. The phase compensator is arranged such that its slow axis (L4) is perpendicular to a slow axis (L3) of tilt components (24a, 24b) in a liquid crystal panel (20), and that an index ellipsoid (41) is tilted in an opposite direction to a tilt direction of the tilt components (24a, 24b).
