  • Patent number: 9119033
    Abstract: An improved system and method for defining an event based upon an object location and a user-defined zone and managing the conveyance of object location event information among computing devices where object location events are defined in terms of a condition based upon a relationship between user-defined zone information and object location information. One or more location information sources are associated with an object to provide the object location information. One or more user-defined zones are defined on a map and one or more object location events are defined. The occurrence of an object location event produces object location event information that is conveyed to users based on user identification codes. Accessibility to object location information, zone information, and object location event information is based upon an object location information access code, a zone information access code, and an object location event information access code, respectively.

  • Patent number: 9047829
    Abstract: An image display apparatus includes a dimming value determination circuit for determining a dimming value of a backlight based on an input image signal, an image signal compensation circuit for compensating the input image signal supplied to a liquid crystal panel in accordance with the dimming value, and a backlight drive circuit for driving and controlling the backlight in accordance with the dimming value. When the light emitting luminance of the present frame of the backlight increases relative to the light emitting luminance of the previous frame, the backlight drive circuit delays the timing for applying the dimming value of the present frame. This makes it possible to reduce power consumption of the backlight by suppressing deterioration in the image quality in spite of the sharp change in the display image luminance.
