The common solution for a field programmable gate array (FPGA)-based time-to-digital converter (TDC) is constructing a tapped delay line (TDL) for time interpolation to yield a sub-clock time resolution. The granularity and uniformity of the delay elements of TDL determine the TDC time resolution. In this paper, we propose a dual-sampling TDL architecture and a bin decimation method that could make...
Few of the current injection technologies can be applied to those human cells whose diameters are ranged about 10–25 (im only. This paper reports our most recent effort in developing a robot-aided microinjection system to solve the challenging problem of automated injection on human cells. A unique microfluidic cell holding chip is designed and fabricated to trap the single cells in the predefined...
In a robotic cell injection system, the penetration force applied on the cell reflects the changes of the physical behavior of the cell. The force, if not controlled properly, may damage to the cells or even lead to death of the cells. The current cellular force measurement is limited by the inherent cantilever structure of the sensor, which may not be applicable to a practical cell injection system...
