Abstract: A system for controlling relative delivery of a therapeutic during a surgical intervention, having: a base; a frame having a proximal end and a distal end; a first subassembly having: a syringe carriage configured to interface with the frame and be moveable relative thereto; a plunger shaft having a proximal end and a distal end, the plunger shaft connected to the frame; and an instrument clamp configured to interact with the plunger shaft; and a syringe having a delivery cannula attached to a syringe body and a syringe plunger, the syringe held by the syringe carriage, where when the syringe plunger is secured to the instrument clamp, the syringe plunger is held in place by the instrument clamp such that the syringe plunger moves relative to the syringe body to cause delivery of a therapeutic as the syringe carriage moves and the delivery cannula is withdrawn.

Abstract: Provided herein are devices, systems, and methods for providing controlled delivery of a therapeutic substance during a surgical procedure, the devices and systems including a base, a frame having a proximal end and a distal end attached to the base, an injection subassembly including a plunger shaft, a relative motion subassembly including a lever plate, and a fastener configured to connect the plunger shaft of the injection subassembly and the lever plate of the relative motion subassembly.

Abstract: Methods of forming a semiconductor structure include providing an insulation layer on a semiconductor layer and diffusing cesium ions into the insulation layer from a cesium ion source outside the insulation layer. A MOSFET including an insulation layer treated with cesium ions may exhibit increased inversion layer mobility.

Abstract: An aerodynamic seal assembly for a rotary machine includes multiple sealing device segments disposed circumferentially intermediate to a stationary housing and a rotor. Each of the segments includes a shoe plate with a forward-shoe section and an aft-shoe section having multiple labyrinth teeth therebetween facing the rotor. The sealing device segment also includes multiple flexures connected to the shoe plate and to a top interface element, wherein the multiple flexures are configured to allow the high pressure fluid to occupy a forward cavity and the low pressure fluid to occupy an aft cavity. Further, the sealing device segments include a secondary seal attached to the top interface element at one first end and positioned about the flexures and the shoe plate at one second end.

The assembly includes multiple sealing device segments disposed circumferentially intermediate to a stationary housing and a rotor. Each of the segments includes a shoe plate with a forward-shoe section and an aft-shoe section having multiple labyrinth teeth therebetween facing the rotor. The shoe plate is configured to allow a high pressure fluid to a front portion of the plurality of the labyrinth teeth and a low pressure fluid behind the plurality of the labyrinth teeth and further configured to generate an aerodynamic force between the shoe plate and the rotor. The sealing device segment also includes multiple bellow springs or flexures connected to the shoe plate and to a top interface element, wherein the multiple bellow springs or flexures are configured to allow the high pressure fluid to occupy a forward cavity and the low pressure fluid to occupy an aft cavity.

Abstract: A system to equalize pressure connected to a compressor for use in HVAC&R system is provided. The system includes a component in fluid communication between a high pressure side and an intermediate pressure side of the compressor. The component is configured to permit flow of refrigerant between the high pressure side and the intermediate pressure side at least when the compressor is not in operation.

Abstract: A scroll compressor (10) is disclosed which includes a fixed scroll element (12) and an orbiting scroll element (14). Each of the scroll elements has a planar surface (18, 24) extending from the wrap on the element to the peripheral edge of the element. A relief area (56) is formed in each of the scroll elements through the planar surface to move the effective pivot point of the intermediate pressure force counteracting the tangential gas force radially inwardly toward the centerline of the scroll elements. A reduction in friction forces is the result, as well as a decrease in the time necessary to work in the scroll elements.
