The spot beam hopping packet scheduler system includes a downlink queue that is coupled to the burst assembly/congestion controller and receives the downlink cell ID and packet burst memory pointers. A cache is coupled to the downlink queue and receives and stores data from the downlink queue.

Abstract: An adjustable connecting rod system includes a reliable, rapidly responsive mechanism for varying effective connecting rod length to vary the compression ratio of the engine. The mechanism may employ the momentum of connecting rod components during operation of the engine to provide actuation force to vary connecting rod length. Connecting rod length is preferably controlled by manipulation of fluid-actuated locking members. In a preferred embodiment, hydraulic pressure is applied through the use of engine oil or other hydraulic fluids. The connecting rod preferably employs one or more movable compression members such as roller members or other mechanical components that may be shifted from one position to another with relatively little friction in order to vary the effective length of the connecting rod. The movable compression members may engage surfaces of both the crankpin bearing retainer and the connecting rod body, loaded in compression to transmit forces therebetween.

Abstract: A voltage tracking system for an ion thruster includes a discharge chamber, a screen grid, an accelerator grid, and an accelerator grid voltage controller. The discharge chamber contains plasma at a given potential. The screen grid is adjacent to the discharge chamber and is voltage biased relative to the plasma to form a plasma sheath that repels electrons and attracts ions from the discharge chamber plasma. The accelerator grid is adjacent to the screen grid and has a voltage for accelerating the ions to create thrust and prevent any electrons from backstreaming into the ion thruster from the beam plasma. The accelerator grid voltage controller supplies voltage to the accelerator grid. The accelerator grid voltage controller adjusts the magnitude of the accelerator grid voltage to minimize the amount of voltage required to prevent electron backstreaming into the ion thruster.
