Abstract:
An ion energy analyzer is described for use in diagnosing the ion energy distribution (IED) of ions incident on a radio frequency (RF) biased substrate immersed in plasma. The ion energy analyzer comprises an entrance grid exposed to the plasma, an ion selection grid disposed proximate to the entrance grid, an electron rejection grid disposed proximate to the ion selection grid, and an ion current collector disposed proximate to the electron rejection grid. The ion selection grid is coupled to an ion selection voltage source configured to positively bias the ion selection grid by an ion selection voltage, and the electron rejection grid is coupled to an electron rejection voltage source configured to negatively bias the electron rejection grid by an electron rejection voltage. Furthermore, an ion current meter is coupled to the ion current collector to measure the ion current.
Abstract:
A method is provided for creating a plurality of substantially uniform nano-scale features in a substantially parallel manner in which an array of micro-lenses is positioned on a surface of a substrate, where each micro-lens includes a hole such that the bottom of the hole corresponds to a portion of the surface of the substrate. A flux of charged particles, e.g., a beam of positive ions of a selected element, is applied to the micro-lens array. The flux of charged particles is focused at selected focal points on the substrate surface at the bottoms of the holes of the micro-lens array. The substrate is tilted at one or more selected angles to displace the locations of the focal points across the substrate surface. By depositing material or etching the surface of the substrate, several substantially uniform nanometer sized features may be rapidly created in each hole on the surface of the substrate in a substantially parallel manner.

Abstract:
The invention relates to a mechanism for performing multicast transmission in a cellular network. In order to enable establishment of resources only in cells containing members of the multicast group and to avoid congestion on the uplink channel, a multicast service notification is transmitted to mobile stations, thereby informing members of the multicast group of an upcoming multicast session. The moment for a response to said multicast service notification is selected in the mobile stations and a presence report is sent from at least one of said mobile stations at the response moment of said at least one mobile station. The presence report or reports are received within a radio access network, and radio resources are established for multicast transmission in a cell of the cellular network when the presence report(s) received in said cell meet(s) predetermined criteria.
Abstract:
A chamber component configured to be coupled to a processing chamber is described. The chamber component comprises one or more adjustable gas passages through which a process gas is introduced to the process chamber. The adjustable gas passage may be configured to form a hollow cathode that creates a hollow cathode plasma in a hollow cathode region having one or more plasma surfaces in contact with the hollow cathode plasma. Therein, at least one of the one or more plasma surfaces is movable in order to vary the size of the hollow cathode region and adjust the properties of the hollow cathode plasma. Furthermore, one or more adjustable hollow cathodes may be utilized to adjust a plasma process for treating a substrate.
Abstract:
A chamber component configured to be coupled to a process chamber and a method of fabricating the chamber component is described. The chamber component comprises a chamber element comprising a first surface on a supply side of the chamber element and a second surface on a process side of the chamber element, wherein the chamber element comprises a reentrant cavity formed in the first surface and a conduit having an inlet coupled to the reentrant cavity and an outlet coupled to the second surface. Furthermore, the chamber component comprises an insertable member configured to couple with the reentrant cavity, the insertable member having one or more passages formed there through and each of the one or more passages are aligned off-axis from the conduit, wherein the one or more passages are configured to receive a process fluid on the supply side and the conduit is configured to distribute the process fluid from the one or more passages on the process side.
Abstract:
A method for sending a data packet, which directly or indirectly indicates a quality-of-service requirement, to a mobile node from a correspondent node via a multi-bearer network, or MBN, that provides at least one interface unit to each of multiple alternative bearer networks between the MBN and the mobile node includes, in one embodiment, selecting an optimal bearer network for sending a data packet between the MBN and the mobile node based on the quality-of-service requirement of the data packet in question; traffic load data related to the multiple bearers; interface unit availability information; and bearer type preference information.
Abstract:
An atraumatic hemostatic clamp, being an artery/vein clamp in the field of medical instruments, mainly includes a left clamp body (1) and a right clamp body (2) which are joined by a hinge and may be divided into jaws (3) and handles (4) by the hinge. The jaws (3) have a curved configuration with ends extending upwardly. Serrated portions (8) with serrations projecting from engaging surfaces are formed on both ends of each of the jaws (3) of the left and right clamp bodies (1), (2). A groove (9) is formed between the serrated portions (8) on both ends. Therefore, this atraumatic hemostatic clamp has a simple structure and can provide a reliable grasp without causing trauma to bodily vessels, thus solving the problem of the conventional hemostatic clamp that vessel trauma may be easily caused.
Abstract:
A magnetic stimulation apparatus for central nervous system and circuit thereof and use of the apparatus and method of using the apparatus are shown. Controlling circuit design and outputting wave form signal to a drive power supply circuit enables the drive power supply circuit to output current of corresponding wave form to coils, and by means of the design of the shape, number of turns, size, interval of the coils, generates within a certain region inside the coils a desired time-variant magnetic field which is then applied to the brain of an animal or a human being so that the central nervous system can receive a wide area synergy magnetic stimulation with a precise wave form, high frequency or a combination of a plurality of frequency components, thus achieving the treatment of nervous and psychiatric diseases or brain function improvement in combination with behavior guidance, thought guidance, or psychological guidance.
Abstract:
A digital broadcast (DB) receiver and methods are provided for processing Internet data. The DB receiver receives service identification information mapping a broadcast service component to a unique transmission stream. The DB receiver also receives at least one announcement message mapping an Internet protocol address to a broadcast service component. Using the information, the DB receiver may configure a demultiplexer to filter transmission streams according to an Internet protocol address.
