A data interface based on USB bus technology for full auto patch-clamp system / 生物医学工程学杂志

A USB bus based data interface technology for full auto Patch-Clamp system is discussed in the article. The main controller is CY2131QC (Cypress) and the logic controller is EPM3256A (Altera). Optocouplers are used to get rid of the noise from the interface. It makes the installation of the Patch-Clamp system easier by using the USB bus, and is suitable for the new generation of the Patch-Clamp system with a high speed of 1M bytes/s.

Application of FPGA to the elimination of 50Hz noise in physiological signals / 医疗卫生装备

The application of Field Programmable Gate Array (FPGA) to the elimina tion of 50Hz noise in physiological signal, such as ECG signal, is discussed in this article. The high speed and flexibility are acquired because of FPGA's app lication, which give the system the ability to acquire and process multi bio-par ameters.
