  • Publication number: 20230272926
    Abstract: An indoor unit for an air conditioner, in which a diffuser outlet through which humidified air is discharged is placed between a front panel and a grill that guides the discharged air, may produce the effect that discharged air pushes discharged humidified air, thereby allowing the humidified air to flow far away from a lateral outlet. As a result, formation of droplets on a surface of the front panel made of a metallic material may be minimized.

  • Publication number: 20100199178
    Abstract: A screen output control device of a mobile communication terminal includes a first screen output unit to output a first portion of a web page on a first screen, and a second screen output unit to output a second portion of the web page on a second screen. The first portion is a scaled down version of the web page, and the second portion is part of the first portion. The second portion may be enlarged relative to the first portion to be displayed in a scale that is more visible by a user. A user may navigate the web page through a user input to the first screen or the second screen. Another screen output control device divides a web page into areas, each of which is synchronized with inputs of an operation unit so that an area can be selected for display by entering the corresponding input.

  • Patent number: 5502487
    Abstract: A character signal display for a camcorder includes a character signal generator for providing needed character data responsive to horizontal and vertical sync signals separated from a selected video signal. According to one aspect of the invention, the vertical sync signal is extracted from the selected video signal by a microcomputer while the horizontal sync signal is extracted from the selected video signal using a Hsync signal oscillator associated with an electronic viewfinder. When an external video signal is input, selection between the external video signal and the camera video signal is arbitrary; when the external video signal is not applied, the camera video signal is preferentially selected. According to another aspect of the invention, circuitry associated with the electronic viewfinder can generate both the horizontal and vertical sync signals needed by the character generator.
