A nano particle reinforced polymer element of a stator and rotor assembly for a power section of a positive displacement fluid motor or a progressive cavity pump. Nano-sized particles are blended with an uncured polymer to improve the physical and chemical properties of the polymer. The use of nano-sized particles reduces the quantity of reinforcement material required to manufacture the polymer for the stator and rotor assembly and lowers the viscosity of the uncured polymer to improve manufacturing characteristics. The use of chemically functionalized nano particles improves the chemical and physical characteristics of the polymer.

A method for performing a common cancel (CC) function on a dynamic random access memory (DRAM) semiconductor device to improve reliability and speed of a memory system. The CC function rakes advantage of the intrinsic delays associated wit memory read operations at high clock frequencies, and the increased write latency commensurate with increased read latencies where non-zero larencies for read and write operations are the norm by permitting address and command ECC structures to operate in parallel with the address and command re-drive circuitt The CC function is extendable to future DDR2 and DDR3 operating requirements in which latency of higher frequency modes will increase due to the shift from 2 bit pre-fetch to 4 and 8 bit pre-fetch architecture.

A strengthened glass container or vessel such as, but not limited to, vials for holding pharmaceutical products or vaccines in a hermetic and / or sterile state. The strengthened glass container undergoes a strengthening process that produces compression at the surface and tension within the container wall. The strengthening process is designed such that the tension within the wall is great enough to ensure catastrophic failure of the container, thus rendering the product unusable, should sterility be compromised by a through-wall crack. The tension is greater than a threshold central tension, above which catastrophic failure of the container is guaranteed, thus eliminating any potential for violation of pharmaceutical integrity.
