摘要:
A networking system may include one or more nodes communicating with each other. The nodes may communicate via one or more links, which a switch or other structure may provide. The networking system may include one or more pools of at least one network diagnostic module. A network diagnostic module may test one or more links and may be configured to rove among a plurality of links. The networking system may include an alarm module. The alarm module may configure one or more network diagnostic modules to test a link. Preferably, the alarm module may, at least partially in response to a first network diagnostic module detecting particular conditions on a link, configure one or more other network diagnostic modules to test a link. The alarm module may configure the one or more other network diagnostic modules according to priority.

An apparatus and method monitor RTP streams between first and second endpoints within a network. A network analyzer is connected at an intermediate point between the first and second endpoints within the network, to extract and process data from RTCP packets to select and monitor the RTP streams accumulated therein having a worst-case jitter and packet loss within the network.
摘要:
Method and apparatus for analyzing intra-cell delay times. The delay time between cells is measured and the number of times the measured delay times equals each of a plurality of predefined values is calculated. A graph is displayed indicating the count for each of the plurality of predefined values.
摘要:
A magnetron sputtering cathode for use in a vacuum deposition process is disclosed wherein the cathode is coated on its sides with an electrically insulating material such as alumina to prevent arcing, and wherein the first end surface of the cathode supports a material to be sputtered. The bottom of the cathode may also be coated with an electrically insulating coating or may be resting upon an insulating platform.

Individual probe management is accomplished in a measurement system by communicating configuration data to each probe based on that probe's received metadata. In one embodiment, the configuration data is sent from a server and the server does not keep track of the probe's configuration. The configuration data can be, for example, parameters used to directly configure the probe or software modules for running on the probe.

The invention relates to a partially disposable substrate holder used in magnetic latches for securing substrates on a planetary rotating platform suspended above a coating source in a vacuum chamber of a vapor deposition system, e.g. a chemical vapor deposition (CVD) system or a physical vapor deposition (PVD) system. The substrate holder includes a reusable base formed, at least partially, from a ferro-magnetic material, which is attracted to the magnetic latch, and a disposable cover formed from a relatively inexpensive, ferromagnetic, easily formable material, which encourages adherence of coating material and has a low vapor pressure at coating temperatures.

An apparatus and method is provided for sensing which faults have occurred in a laser control system, as well as trapping and identifying the first fault occurrence. The apparatus includes an integrated circuit in which a mask register is set by means of a micro-controller or a host system to select which fault sources are to be recorded. A status bit register in which the fault indications are stored can also be interrogated by the micro-controller or a host system. A settable first fault status register determines whether every fault or only the first fault gets recorded.

A large micro-mirror, e.g. 3 mm by 4 mm, in accordance with the present invention has sufficient rigidity to ensure a low mirror curvature, e.g. a radius of curvature greater than 5 meters, and a low mass in order to ensure a high oscillation frequency, e.g. greater than 1000 Hz. A method of making the micro-mirror utilizes bulk micro-machining technology, which enables the manufacture of a honeycomb structure sandwiched between two solid and smooth silicon layers without any indentations or holes. The honeycomb sandwich structure provides the rigidity and low mass needed to obtain a micro-mirror with a low mirror curvature and high resonant frequency.
