摘要:
Given simultaneous connection of the subscriber line circuits by way of a main distributor to a new switching center and to an existing or old switching center, the subscriber terminals are successively selected proceeding from the new switching center and the old switching center produces connections from a test terminal to these subscriber line circuits. A tone generator of the new switching center supplies a test code word by way of these connections that proceeds via a termination-associated test connection contact and via an external test bus to a code character receiver of the new switching center and is checked therein for coincidence with the test code word.

An improved method and apparatus for shutting down and restoring an ion beam in an ion beam system. Preferred embodiments provide a system for improved power control of a focused ion beam source, which utilizes an automatic detection of when a charged particle beam system is idle (the beam itself is not in use) and then automatically reducing the beam current to a degree where little or no ion milling occurs at any aperture plane in the ion column. Preferred embodiments include a controller operable to modify voltage to an extractor electrode and/or to reduce voltage to a source electrode when idle state of an ion source of the charged particle beam system is detected.

Providers may use mobile devices to access mobile drug sampling services from a drug sample promotional ecosystem. The drug sample promotional ecosystem includes a promotional orchestration engine which comprises a services engine that provides transactional responses to a provider's request, such as informational results being returned to the provider or request for further actions that will be forwarded. An analysis engine stores data and provides tactical and strategic level analysis. The learning engine is a mechanism by which the promotional orchestration engine adapts itself to changing conditions. The learning engine preferably customizes various components of the services engine and components of the analysis engine. From a provider's standpoint, the learning engine allows components of the services engine to be personalized to the particular provider.

A system and method are disclosed for alternate multi-channel bi-directional data transmission in a multi-unit environment. In one embodiment, legacy infrastructure connects entertainment centers in respective rooms to a service server to provide downstream communication from the service server to the entertainment center. To provide bi-directional data transmission, an upstream data transmission channel is provided which includes multiple transmission mediums from the entertainment centers to the service center. The resulting bi-directional channel is asymmetrical with respect to bandwidth and the upstream communication link includes non-continuous bandwidth links.

Systems and methods for processing, transmitting, and displaying data received from a continuous analyte (e.g., glucose) sensor are provided. A sensor system can comprise a sensor electronics module that includes power saving features, e.g., a low power measurement circuit that can be switched between a measurement mode and a low power mode, wherein charging circuitry continues to apply power to electrodes of a sensor during the low power mode. The sensor electronics module can be switched between a low power storage mode and a higher power operational mode via a switch, e.g., a reed switch or optical switch. A validation routine can be implemented to ensure an interrupt signal sent from the switch is valid. The sensor can be physically connected to the sensor electronics module in direct wireless communication with a plurality of different display devices.
摘要:
A method for rapid switching between operating modes with differing beam currents in a charged particle system is disclosed. Many FIB milling applications require precise positioning of a milled pattern within a region of interest (RoI). This may be accomplished by using fiducial marks near the RoI, wherein the FIB is periodically deflected to image these marks during FIB milling. Any drift of the beam relative to the RoI can then be measured and compensated for, enabling more precise positioning of the FIB milling beam. It is often advantageous to use a lower current FIB for imaging since this may enable higher spatial resolution in the image of the marks. For faster FIB milling, a larger beam current is desired. Thus, for optimization of the FIB milling process, a method for rapidly switching between high and low current operating modes is desirable.
摘要:
A focused ion beam (FIB) system is disclosed, comprising an inductively coupled plasma ion source, an insulating plasma chamber containing the plasma, a conducting source biasing electrode in contact with the plasma and biased to a high voltage to control the ion beam energy at a sample, and a plurality of apertures. The plasma within the plasma chamber serves as a virtual source for an ion column comprising one or more lenses which form a focused ion beam on the surface of a sample to be imaged and/or FIB-processed. The plasma is initiated by a plasma igniter mounted near or at the column which induces a high voltage oscillatory pulse on the source biasing electrode. By mounting the plasma igniter near the column, capacitive effects of the cable connecting the source biasing electrode to the biasing power supply are minimized. Ion beam sputtering of the apertures is minimized by proper aperture materials selection.
