Abstract: The present disclosure provide a detection device of microfluidic polymerase chain reaction (PCR) and a detection system including the same. This all-in-one device and system may be used to detect at least one biological detection chip, so that can amplify gene fragments at the front-end and detect them at the back-end immediately, decreasing the time required for the analysis, enabling real-time, low-cost, and rapid detection of various viruses, such as EBV and COVID-19, without compromising accuracy or sensitivity.

Abstract: A milliactuator integrated with driver and relative position error sensor circuits formed on a single silicon substrate. The integrated milliactuator/electronics module is positioned between the suspension and the slider/transducer assembly to provide rapid, small motion position control of the slider/transducer over data tracks on the disk of a magnetic disk drive. Integration of the milliactuator electronics with the milliactuator reduces parasitic loading and interference problems with the magnetic transducer signals. Electronic circuits are built on a silicon wafer followed by deposition of a planarization layer and a ground plane layer for isolation from the milliactuator which is then built on top of the circuits.

Abstract: A device for removing degraded concrete from a layer of concrete (11). The device includes a carrier (12) and a guide mechanism (13) on the carrier for guiding a nozzle device (14) along a path above the concrete layer. The nozzle device is provided with a noncavitating nozzle (16) which is inclined relative to the concrete layer such that the nozzle points in the direction of movement of the nozzle device for either direction of movement of the nozzle device.
