Abstract: There is described an acrylic polyester resin, obtainable by grafting an acrylic polymer with a polyester material. The polyester material is obtainable by polymerizing (i) a polyacid component, with (ii) a polyol component, including—2,2,4,4-tetraallcylcyclobutane-1,3-diol. One of the polyacid component or the polyol component comprises a functional monomer operable to impart functionality on to the polyester resin, such that an acrylic polymer may be grafted with the polyester material via the use of said functionality. Also provided is an aqueous coating composition comprising the acrylic polyester resin and a metal packaging containing coated with the composition.

Abstract: A lighted display device that includes a display device, a backlight device and an electrical delay circuit. The backlight device is disposed proximate the display device and configured to emit light directed to the display device. The ambient light sensor is configured to generate a signal to adjust a brightness level of the light from the backlight device based on a change in input ambient light. The electrical delay circuit is configured to apply a fixed, non-user configurable time delay to delay the adjustment of the brightness level of the light from the backlight.

Abstract: A method and apparatus for reducing display brightness on a portable computer when a user switches from an AC adapter to a battery power source provide battery power conservation. The reduction in display brightness is performed gradually so that a sudden brightness drop is not detected by the user. The display brightness reduction is preferably performed sufficiently gradually so that the reduction in brightness is virtually unnoticeable to the human eye.
