Abstract: Provided herein are isolation processes and the associated hardware to allow fluid streams to be isolated from a sterilized system (e.g., a sterile process vessel) that contains a sterile process. The isolation processes described herein allow for continuous removal of fluid streams (e.g., waste streams, liquid containing recombinant therapeutic proteins) from a sterilized system (e.g., a biological manufacturing system), which provides for less manual manipulation of the sterilized system and a decreased risk of contaminating the sterilized system.

Abstract: A method for determining a lowest stimulation threshold current level in a group of channels of a neuromonitoring device. The method includes stimulating tissue at a current level from a predetermined range of current levels as a sequence of pulses delivered at a frequency. The stimulating includes increasing the current level of each pulse in the sequence of pulses from an immediately preceding pulse by a first current increment. The method includes determining that a first evocation pulse from the sequence of pulses evokes a first muscular response. The method includes stimulating the tissue with a second evocation pulse from the sequence of pulses to evoke a second muscular response. The stimulating includes decreasing the frequency of the delivery of each pulse in the sequence of pulses and increasing the current level of each pulse in the sequence of pulses from the immediately preceding pulse by a second current increment.

Abstract: A power detection device for a facility monitoring system provides non-contact power detection in a power supply line for determining a powered up or energized state of equipment connected to the power supply line. The power detection device is adapted to be disposed in communication with a live power supply line without disconnecting or interrupting the power supply to the powered equipment. A hinged casing including a sensor circuit for detecting electrical current is frictionally engaged to the power supply line by closing the hinge and drawing opposed sides of the casing together. Sensor signals are aggregated and amplified such that an amplified signal above a threshold is indicative of a current flow sufficient to power the equipment and render a determination of an energized, or “equipment on” state. Conversely, the lack of a threshold signal indicates inactive equipment such that remedial measures may be commenced.
