The software is currently produced by SoftRail (formerly Signal Computer Consultants) for Windows-based computers. The simulator is operated from the perspective of a CTC dispatcher. Track diagrams similar to actual CTC displays are provided, and train operations run according to a timetable. Operations can be run in real time or adjusted fast ...

The 2N7000 is housed in a TO92 package, with lead 1 connected as the source, lead 2 as the gate, and lead 3 as the drain. The BS170 has the source and drain leads interchanged. The 2N7002 variant is packaged in a TO-236 surface-mount package. The 2N7000 is an N-channel, enhancement-mode MOSFET used for low-power switching applications. [1]
IEEE 1451 is a set of smart transducer interface standards developed by the Institute of Electrical and Electronics Engineers (IEEE) Instrumentation and Measurement Society's Sensor Technology Technical Committee describing a set of open, common, network-independent communication interfaces for connecting transducers (sensors or actuators) to microprocessors, instrumentation systems, and ...
SDI-12 (Serial Digital Interface at 1200 baud) is an asynchronous serial communications protocol for intelligent sensors that monitor environment data. These instruments are typically low-power (12 volts), are used at remote locations, and usually communicate with a data logger or other data acquisition device.
iText is a library for creating and manipulating PDF files in Java and . NET.It was created in 2000 and written by Bruno Lowagie. The source code was initially distributed as open source under the Mozilla Public License or the GNU Library General Public License open source licenses.
Figure 3: PNP version of the emitter-follower circuit, all polarities are reversed. A small voltage change on the input terminal will be replicated at the output (depending slightly on the transistor's gain and the value of the load resistance; see gain formula below). This circuit is useful because it has a large input impedance
Cam-follower dwell mechanisms are used in pairs in sewing machines to operate the four motion feed dogs, with one cam moving the dog up and down, and the other cam moving the dog forwards and backwards. The cams in this application are usually phased 90 degrees apart allowing a pause in the up/down movement of the dog while it is being moved ...
