The present invention provides a method and system of storing information for drawing an object on a computer system that includes providing a palette file that includes a set of first labels matched with numerical values, tagging a vector graphics file for drawing the object with second labels, translating the second labels into one or more of the first labels, and plugging in values stored in the palette file associated with the translated second labels into the tagged vector graphics file.

Flexible interface using scalable vector graphics with metalevel palette

An efficient multicast key management is achieved by using seals. A security server generates a seal. In one embodiment, the seal contains a key. In another embodiment, the seal contains information for generating a key. An application server requests the seal from the security server and broadcasts the seal to a plurality of recipients. A recipient wishing to encrypt or decrypt a data stream transmits the received seal to the security server to be opened. If the recipient is authorized, the security server transmits a permit to the authorized recipient. In one embodiment, the recipient generates a key from the permit. In another embodiment, the permit is the key. If the recipient is a sender, the recipient encrypts data using the key and broadcasts the same encrypted data stream to all receivers. If the recipient is a receiver, the recipient decrypts an encrypted data stream using the key. In one embodiment, a seal with a corresponding offset value is sent periodically in a data stream. In another embodiment, multiple instances of identical seals are opened only once. In yet another embodiment, a seal is appended to each datagram packet. In a further embodiment, a seal is appended to any data stream.

A cooling system and method are provided for cooling a heater block located in a cylindrical processing chamber of a wafer processing apparatus. The cooling system includes first and second frame assemblies having respective ends adapted to rest on an upper peripheral surface of the processing chamber, and fan assemblies mounted to the frame assemblies at spaced locations therealong. A first pair of fan assemblies are directed to push air into the processing chamber, and a second pair of fan assemblies are directed to pull air out of the processing chamber. The fan assemblies are arranged such that they circulate ambient air through the processing chamber to provide a rapid cooling of the heater block to a safe working temperature. The frame assemblies have an adjustable length that can be adjusted to fit processing chambers having different sizes and configurations. The cooling system substantially reduces the cooling time required for the heater block to reach a safe working temperature as compared to conventional cooling by free convection.
