Abstract: The present invention discloses a multifunctional Petri dish with two sealing structures to ensure that the water in the medium will not evaporate during continuous culture, further affecting cultured living material growth and development. In addition to alcohol spray, the multifunctional Petri dish allows the application of acids, alkalis, alcohols, peroxides solution, or peroxides gas to immerse the multi-purpose Petri dish to remove bacteria or viruses. Various accessory devices can meet all requirements for a living culture of cells and tissues that the existing Petri dishes cannot provide. Using the dish cover operator and the dish container operator is essential to ensure that the researcher's hands will not directly touch the Petri dish in the sterile operating bench, thereby blocking all potential contamination of the medium and culture by foreign organisms. The labeling and labeling reading recorder with the multifunctional Petri dish provides more convenient and accurate electronic data establishment and reading for in vitro culture.

Abstract: A connector assembly for connection and disconnection between ports of fluid lines for administering fluids into a human body from a route other than the oral route. The connector assembly includes a catheter dock, a cap removal dock, a fluid line dock, and a new cap dock. The catheter dock can receive an inlet port of a catheter secured by a catheter cap. The cap removal dock can aseptically remove the catheter cap from the inlet port. The catheter dock can be switched consecutively between the cap removal dock, the fluid line dock, and the new cap dock. Upon removal of the catheter cap, the catheter dock can be switched to the fluid line dock, and the fluid can flow from the fluid line to the catheter. Upon administering the liquid, the catheter dock can be switched from the fluid line dock to the new cap dock, wherein a new catheter cap is secured into the inlet port under aseptic conditions.

Abstract: A demand-based load balancing function may be provided by one or more drive controllers that takes advantage of the affinity laws to linearize the control of the variable of interest (e.g., flow, pressure, etc.). Each drive controller may be set up by the user simply inputting a few values into the drive controller. Based on the inputs, the drive controllers may interpolate control points using an assumed linear relationship between the variable to be controlled (e.g., pressure) and the current driven to the pump. Feedback data from the system may be used to continually update the drive controllers so as to potentially allow them to better balance power usage to each pump.

Abstract: A non-volatile memory cell and array structure is disclosed situated within a high voltage region of an integrated circuit. The cell utilizes capacitive coupling based on an overlap between a gate and a drift region to impart a programming voltage. Programming is effectuated using a drain extension which can act to inject hot electrons. The cell can be operated as a one-time programmable (OTP) or multiple-time programmable (MTP) device. The fabrication of the cell relies on processing steps associated with high voltage devices, thus avoiding the need for additional masks, manufacturing steps, etc.

Abstract: A method and system for up-vector detection for ribs in a 3D medical image volume, such as a computed tomography (CT) volume is disclosed. A rib centerline of at least one rib is extracted in a 3D medical image volume. An up-vector is automatically detected at each of a plurality of centerline points of the rib centerline of the at least one rib. The up-vector at each centerline point can be detected using a trained regression function. Alternatively, the up-vector at each centerline point can be detected by detecting an ellipse shape in a cross-sectional rib image generated at each centerline point.
