20130300490 | RETURN-TYPE CURRENT-REUSE MIXER - A return-type current-reuse mixer having a transconductance/amplification stage, a mixing stage, and a high-pass and a low-pass filter network. The transconductance/amplification stage has a current-reuse CMOS topology wherein an input frequency signal is converted into a frequency current, low-frequency components are removed from the frequency current by the high-pass filter network, the frequency current is fed into the mixing stage, modulation occurs in the mixing stage, and then an intermediate-frequency signal is generated and output. Once high-frequency components are removed from the intermediate-frequency signal by the low-pass filter network, the intermediate-frequency signal is sent again for input into the transconductance/amplification stage, then amplified in the transconductance/amplification stage and output. The mixer transconductance/amplification stage employs a current-reuse technique. The input frequency and the output intermediate-frequency signal share a common transconductance/amplification stage. The mixer reduces power consumption, simplifies the circuit topology, and provides high conversion gain. | 11-14-2013 |

20140305008 | SHOE SOLE AND FOOTWEAR CONSTITUTED THEREOF - A new design of shoe sole that includes both a base portion and a base support portion, wherein said base support portion is a base support portion attached underneath to the center area of said has portion. The current design further includes an expansion portion that extends downwardly from the outside rim of said base portion, wherein said expansion portion is elastic, and the bottom surface of said base support portion is higher than the bottom surface of said expansion portion. Footwear made of this type of sole first touch a support surface (ground) with the expansion portion, which forms a first contact region. Further because the expansion portion is located at the outward rim of the base portion, it is easier for the expansion portion to extend to all directions when pressed. It allows a first round of shock absorption in both longitudinal and cross-sectional directions. As the pressure on the shoe sole increases, the expansion portion is expanded, and the base support portion starts its contact with the surface. The deformation of both the expansion portion and base support portion allows a second round of shock absorption. When this occurs, the deformations of both the expansion portion and base support portion lowers the height of the shoe sole, expands the support area of the outsole, and leads to stronger joint support of the wearer. | 10-16-2014 |
