Abstract: AIMS is design to eventually have computer provide management function to manage other computers (CMC). The process management algorithms is proven to work on higher level of intelligence as long as the business rule can be represented in the digital logic. This will be relief of management on monitoring various indexes in order to make business decision. By the modularized design, the CMC automation can be operated either an integrated part of AIMS or an independent system outside AIMS.

Abstract: A temperature stable bias circuit for a radio frequency (RF) power amplifier uses current deletion and current supplement techniques to maintain the bias, or reference current of the RF power amplifier at a stable level regardless of the temperature that the power amplifier is operating. When temperature increases, the current deletion circuitry reduces the bias current supplied to the power transistor. When the temperature decreases, the current supplement circuitry increases the bias current supplied to the power transistor. This bias circuitry allows the output of the RF power amplifier to remain constant. The current deletion and current supplement circuitry can be fabricated using the same processing technology as the power amplifier and can be easily integrated into the power amplifier device packaging.
