Abstract: A request to generate one or more random values can be received. In response to receiving the request to generate the one or more random values, a first read operation can be performed on a memory cell of the memory component to retrieve first data and a second read operation can be performed on the same memory cell of the memory component to retrieve second data. The first data can be compared with the second data to identify a difference between the first data and the second data. The difference can be associated with a noise characteristic of the memory cell. The one or more random values can be generated based on the difference between the first data and the second data that is associated with the noise characteristic of the memory cell.

Abstract: An air intake system (AIS) has a plenum and an inlet barrier filter associated with the plenum, through which air can selectively enter the plenum. The AIS also has an inlet duct associated with the plenum, through which air can selectively enter the plenum. The AIS also has a bypass door associated with the inlet duct, the bypass door being configured to selectively change an amount of air allowed to pass through the inlet duct. The AIS also has a filter airflow change device configured to change an amount of airflow allowed through the inlet barrier filter.

Abstract: The exhaust system is located on each nacelle of a tiltrotor aircraft. The exhaust system includes a vector nozzle that is selectively rotatable in relation to each nacelle in order to achieve certain performance objectives. The vector nozzle can be oriented to provide maximum flight performance, reduce infrared (IR) signature, or even to reduce/prevent ground heating.

Abstract: Compounds that include silicon-containing groups, and optionally urethane groups, urea groups, or combinations thereof (i.e., polyurethanes, polyureas, or polyurethane-ureas), as well as materials and methods for making such compounds.

Abstract: The present invention is related to systems and methods for modifying various non-equidimensional substrates with modifying agents. The system comprises a processing chamber configured for passing the non-equidimensional substrate therethrough, wherein the processing chamber is further configured to accept a treatment mixture into the chamber during movement of the non-equidimensional substrate through the processing chamber. The treatment mixture can comprise of the modifying agent in a carrier medium, wherein the carrier medium is selected from the group consisting of a supercritical fluid, a near-critical fluid, a superheated fluid, a superheated liquid, and a liquefied gas. Thus, the modifying agent can be applied to the non-equidimensional substrate upon contact between the treatment mixture and the non-equidimensional substrate.

Abstract: A heart model provides a simulative environment for lead implantation and affixation. In one embodiment, removable silicone plugs are provided at appropriate locations so that an inserted lead can be affixed to the plugs with a helical tip. A simulative venous structure is provided that has increased lubricity to facilitate the insertion and manipulation of the lead.

Abstract: The present invention is related to the modifying of substrates with multiple modifying agents in a single continuous system. At least two processing chambers are configured for modifying the substrate in a continuous feed system. The processing chambers can be substantially isolated from one another by interstitial seals. Additionally, the two processing chambers can be substantially isolated from the surrounding atmosphere by end seals. Optionally, expansion chambers can be used to separate the seals from the processing chambers.
