  • Patent number: 10660239
    Abstract: A cooling system is provided which includes, for instance, a coolant circulation loop, one or more primary coolant pumps, and a fill and drain pump. The primary coolant pump(s) is coupled to facilitate circulating coolant through the coolant circulation loop, and the fill and drain pump facilitates selective filling of the cooling system with the coolant, or draining of the coolant from the cooling system. The fill and drain pump is integrated with the cooling system as a backup coolant pump to the primary coolant pump(s), and circulates the coolant through the coolant circulation loop responsive to an error in the primary coolant pump(s). The primary coolant pump(s) and fill and drain pumps may be different types of pumps, and the cooling system further includes a control system for automatically activating the fill and drain pump upon detection of an error in the primary coolant pump(s).

  • Patent number: 9021782
    Abstract: A laser ignition/ablation propulsion system that captures the advantages of both liquid and solid propulsion. A reel system is used to move a propellant tape containing a plurality of propellant material targets through an ignition chamber. When a propellant target is in the ignition chamber, a laser beam from a laser positioned above the ignition chamber strikes the propellant target, igniting the propellant material and resulting in a thrust impulse. The propellant tape is advanced, carrying another propellant target into the ignition chamber. The propellant tape and ignition chamber are designed to ensure that each ignition event is isolated from the remaining propellant targets. Thrust and specific impulse may by precisely controlled by varying the synchronized propellant tape/laser speed. The laser ignition/ablation propulsion system may be scaled for use in small and large applications.

  • Patent number: 8531025
    Abstract: A semiconductor module structure and a method of forming the semiconductor module structure are disclosed. The structure incorporates a die mounted on a substrate and covered by a lid. A thermal compound is disposed within a thermal gap between the die and the lid. A barrier around the periphery of the die extends between the lid and the substrate, contains the thermal compound, and flexes in response to expansion and contraction of both the substrate and the lid during cycling of the semiconductor module. More particularly, either the barrier is formed of a flexible material or has a flexible connection to the substrate and/or to the lid. The barrier effectively contains the thermal compound between the die and the lid and, thereby, provides acceptable and controlled coverage of the thermal compound over the die for heat removal.
