摘要： Methods and systems for electron emission are disclosed. An example system can comprise a cup-rod-needle assembly that can collect a source of electrons and allow internal space charge build-up and generation of an internal self-electric field build-up. The system can provide self-emission at a predetermined location of the needle in the system. An example system can comprise a cup-rod-needle assembly, an annular dielectric insulator as a plug, a source of electrons to provide electrons into a cup, and a beam drift tube.

摘要： A system collects a source of electrons allowing for internal space charge build-up and hence internal self-electric field build-up that results in self-emission at a predetermined location (needle) in the system using components of: a conducting medium at one end of the structure denoted as the needle having a work function of less than Y eV (typical absolute values 3 to 4 eV) acting like a cathode and allowing for field emission; a conducting rod between the needle and cup to transport collected electrons with work function greater than X eV; an annular dielectric insulator, plug, with rod passing through acts as an electrical and mechanical barrier for mounting and as a barrier for pressure differentials; a source of electrons to provide electrons into the cup portion of the assembly acting like an anode; a beam drift tube to house and enable electron transport to the cup-rod assembly, the surface of the cup and rod have a work function greater than X eV; the plug with rod passing through seals and terminates the beam drift tube at one end; the cup-rod-needle assembly may be isolated electrically; the beam drift tube supporting a vacuum of less than 5 Torr; and wherein X−Y≧2.5.

摘要： A heart and lung support assembly for extracorporeal support of a heart and one or both associated lungs, using the lungs of the donor as oxygenators. The heart and lung support assembly is controlled by an automated feedback control system to monitor and control various attributes of the heart, lungs, and blood, such that the heart and lungs may be stabilized for an extended period of time in an extracorporeal state. The heart and lung support assembly includes generally a housing, a chest cavity actuator assembly, a blood pressure controller assembly, and an automated monitor and feedback control system. The housing is provided for receiving the heart, lungs, and trachea after being removed from the donor patient as a unit. The chest cavity actuator assembly is carried on the exterior of the housing and is provided for simulating normal inhaling and exhaling by the donor lungs. The blood pressure controller assembly is carried by the housing and includes a fluid circuit for the circulation of blood through the heart and lungs to simulate the normal circulation of blood and to provide a means for monitoring the composition and controlling the flow of the blood. The automated monitor and feedback control system includes an arterial cell for detecting at least the partial pressure of oxygen, the partial pressure of carbon dioxide, and pH levels in blood as the blood passes therethrough. A plurality of blood pressure detectors is provided for measuring the various pressures of interest.

摘要： A UNLV novel electric/magnetic dot sensor includes a loop of conductor having two ends to the loop, a first end and a second end; the first end of the conductor seamlessly secured to a first conductor within a first sheath; the second end of the conductor seamlessly secured to a second conductor within a second sheath; and the first sheath and the second sheath positioned adjacent each other. The UNLV novel sensor can be made by removing outer layers in a segment of coaxial cable, leaving a continuous link of essentially uncovered conductor between two coaxial cable legs.
