20130295601 | Systems and Methods for Testing Drugs and Drug Delivery Systems - A system is provided that simulates the in vivo micro-environment of three-dimensional cellular structures or bodies, such as tumors. The system simulates the pressure gradients and fluid flows of the vascular and lymphatic systems as well as the interstitial and capillary transport mechanisms between the 3D cellular structure and the vascular and lymphatic systems. The system can be used to introduce drugs or drug delivery carriers to a tumor, for example, to assess the uptake capability and effect on the tumor. The system maintains the viability of the tumor cells for a sufficiently long period of time to permit testing of several different drugs and/or delivery carriers. | 11-07-2013 |

20160070381 | SEMICONDUCTOR DEVICE AND SEMICONDUCTOR SYSTEM FOR PRODUCING NOISE DIFFERENCES BETWEEN POINTS OF TIME - Provided are a semiconductor device and a semiconductor system, which can increase immunity against noises through tertiary correlated double sampling (CDS). The semiconductor device includes an amplifier that receives noise and a driving signal, resets for each predetermined period of the driving signal and samples the noise to generate first sampled noise. The first sampled noise includes multiple noise differences each occurring between consecutive reset points. A sampler performs second sampling and third sampling on the first sampled noise and performs fourth sampling on the second and third sampled noises. The first sampled noise includes first to third noise differences, the second sampled noise is a difference between the first and second noise differences, the third sampled noise is a difference between the second and third noise differences, and the fourth sampled noise is a difference between the second and third sampled noises. | 03-10-2016 |
20160098117 | TOUCH DISPLAY DEVICE FOR CONTROLLING OFFSET CAPACITANCE CALIBRATION - A touch display device configured to drive a signal line in a first plurality of steps during a line-sensing period and adjust an offset capacitance in a second plurality of steps corresponding to the first plurality of steps. | 04-07-2016 |
