20090100285Internal Clock Signal Generating Circuits Including Frequency Division and Phase Control and Related Methods, Systems, and Devices - An integrated circuit device may include a main clock signal input pad configured to receive a main clock signal having a main clock frequency, a high speed clock signal input pad configured to receive a high speed clock signal having a high speed clock frequency greater than the main clock frequency, a frequency divider, and a phase controller. The frequency divider may be configured to generate a plurality of preliminary internal clock signals responsive to the high speed clock signal wherein each of the preliminary internal clock signals has the same main clock frequency and a different phase. The phase controller may be configured to select one of the preliminary internal clock signals having a phase most closely matched with a phase of the main clock signal, and to translate the preliminary internal clock signals to internal clock signals so that the preliminary internal clock signal having the phase most closely matched with the phase of the main clock signal is translated as a primary internal clock signal, so that the internal clock signals have the main clock frequency. Related methods, systems, and devices are also discussed.04-16-2009

20080254310Article comprising a fine-Grained metallic material and a polymeric material - Lightweight articles comprising a polymeric material at least partially coated with a fine-grained metallic material are disclosed. The fine-grained metallic material has an average grain size of 2 nm to 5,000 nm, a thickness between 25 micron and 5 cm, and a hardness between 200 VHN and 3,000 VHN. The lightweight articles are strong and ductile and exhibit high coefficients of restitution and a high stiffness and are particularly suitable for a variety of applications including aerospace and automotive parts, sporting goods, and the like.10-16-2008
20100028714Fine-Grained Metallic Coatings Having the Coefficient of Thermal Expansion Matched to the One of the Substrate - Fine-grained (average grain size 1 nm to 1,000 nm) metallic coatings optionally containing solid particulates dispersed therein are disclosed. The fine-grained metallic materials are significantly harder and stronger than conventional coatings of the same chemical composition due to Hall-Petch strengthening and have low linear coefficients of thermal expansion (CTEs). The invention provides means for matching the CTE of the fine-grained metallic coating to the one of the substrate by adjusting the composition of the alloy and/or by varying the chemistry and volume fraction of particulates embedded in the coating. The fine-grained metallic coatings are particularly suited for strong and lightweight articles, precision molds, sporting goods, automotive parts and components exposed to thermal cycling. The low CTEs and the ability to match the CTEs of the fine-grained metallic coatings with the CTEs of the substrate minimize dimensional changes during thermal cycling and prevent premature failure.02-04-2010
