Abstract: A device, system and process involve conducting electroporation of microvesicles or exosomes or other target structures in a microfluidic arrangement at pressures that exceed atmospheric pressure. Single as well as multiple flow configurations can be employed. In some cases, the system and its operation are computer-controlled for partial or complete automation.

Abstract: A method of operating a power tool having a motor and a controller is provided. The method includes: setting a protection time limit associated with a condition of the motor; taking protective action to shut down the motor if the condition of the motor persists for a duration of the protection time limit; and in response to occurrence of the condition during a start-up period of operation of the motor, extending the protection time limit for a duration of a constant-clutch time period to allow an output speed of the motor to reach or exceed a speed threshold, and taking protective action to shut down the motor if the output speed of the motor remains below the speed threshold for the duration of the constant-clutch time period.

Abstract: A power tool is provided including a housing; an electric motor disposed within the housing; a main trigger switch mounted on the housing; a side handle mounted on the housing, the side handle having an auxiliary trigger; and a controller disposed within the housing operable to control a flow of electric current from a power source to the electric motor. The controller activates the motor only if the main trigger and the auxiliary trigger are both actuated. If the one of the triggers is released while the other trigger is still engaged, the controller is configured to continue operating the motor only if the released trigger is reengaged within a time threshold, but otherwise discontinue operating the motor until both the main trigger and the auxiliary triggers are released and reengaged.

Abstract: According to various aspects and embodiments, a growth adaptive expandable stent is provided. The expandable stent includes a stent structure having a cylindrical shape that is self-expanding in a radial direction and includes a plurality of cylindrical rings disposed along a longitudinal axis of the stent structure. The stent structure is configured to exert a continuous outward radial force over time when implanted such that a diameter of the stent structure expands from a first value to a second value that is at least about 1.5 times the first value.

Abstract: A tub box for receiving a drain trap is formed from two substantially identical plastic housing portions each including one or more round knockouts in one or more side walls of the housing portions and one or more edge flange knockouts in an edge flange of each housing portion and side walls in line with and terminating in close proximity to the respective round knockouts. Pull tabs on the round knockouts facilitate removal of the round knockouts from the housing portions and limit the amount of nesting of the housing portions inside one another when stacked for storage and shipment so the housing portions can easily be pulled apart when desired. A lip protrudes axially outwardly from the radial outer edge of the edge flange of each housing portion around one half only of the periphery of each edge flange for overlapping engagement with the outer edge of the edge flange of an other housing portion when the edge flanges of two housing portions are placed in engagement with one another.
