Abstract: An information broker is provided which receives information regarding the updating of IP addresses and distributes the information to subscribing Domain Name Service (DNS) or Dynamic Host Configuration Protocol (DHCP) servers. A list of subscribing servers is maintained by the broker. The broker may broadcast information regarding the allocation of a IP addresses to subscribing DNS servers, which then may be added to the DNS databases or the database may be updated with the new information. The broker may also broadcast information regarding the revocation of IP addresses to subscribing DNS servers, which may then be used to clear DNS entries in the database. Revocation of dynamically allocated IP addresses in networks with multiple DHCP servers may also be simplified by using the broker, where the broker broadcasts information regarding the revocation of IP addresses to subscribing DHCP servers.

Abstract: A method for displaying grey-scale images at a desired grey scale resolution up to the visible limit on a display having a matrix of pixels, includes the steps of: defining a plurality of control matrices, each of said control matrices having a size and equal to the desired grey scale resolution of the display, each position in each of said control matrices corresponding to a specific pixel of said display; defining a super matrix, each position in said super matrix corresponding to one of said plurality of control matrices and having an assigned number in a range equal to the desired grey scale resolution; turning on a selected number of pixels within each of said control matrices based upon the grey scale value of the pixel, the orientation of the pixels turned on based on the value of a circular queue of size equal to said desired gray scale resolution; and adjusting the starting value of said circular queue for each of said control matrices based upon the number contained in the position of the super matr
