  • Publication number: 20020167939
    Abstract: A relatively very fast and scalable algorithm, preferably in the form of software residing on a server, is provided for transmitting data in the form of equations or database input to and from small palm OS, pocket PCs, handheld PCs, web enabled phones or convergence devices such as web enabled phones with complete PDA systems built into the phone. The server based algorithm is efficient precisely because it minimizes information through put to and from the PDA. An integral part of the server is a “front end” page, referred to as WDIE feather, where the page is carefully derived not on the basis of “content” but on the basis of “context” which provides the minimum and necessary information to the user.

  • Patent number: 4680510
    Abstract: A color video monitor is disclosed which includes improved digital convergence using a plurality of memory means in which vertical convergence correction values are stored, one memory each for red, green, blue and lateral blue convergence values. Interpolation means provide additional values between the points stored in memory such that a smooth transition between successive lines of the display is achieved. The correction values stored in the memories are generated by means of a high-order polynomial function. The monitor employs synchronization circuitry which synchronizes all digital components to the supplied video signal including horizontal and vertical sync pulses and an external 36 MHz clock associated therewith.
