The TC840 CompactPCI time-to-digital converter module, with 50 ps timing resolution, is made for measuring the time of the rising or falling edge of very fast trigger events, using inputs with programmable thresholds. It is designed to handle large-scale experiments like hydrodynamics, particle accelerator timing, nuclear fusion studies and explosive testing, plus time-of-flight measurement in mass spectrometry and 3D mapping. With a wide-range, single- and multi-start converter, the TC840 uses 13 identical hardware channels: one is the common start, while the rest are independent stop inputs. It works in single-start or multi-start acquisition, and with timing information on all the independent channels encoded relative to the common channel. Up to 512 stops per channel can be recorded with the large internal buffer, and start/stop events up to 20 seconds apart can be recorded. Digitized data goes straight to the onboard FPGA-based data processing unit. This increases data throughout the PC through the direct memory access mode. The TC840 measures time on the internal low jitter (&3 ps rms), high stability (±2 ppm) clock source, or an external 10 MHz reference input. Pricing starts at $11,990, with delivery in six weeks ARO.
Machine vision and video streaming systems are used for a variety of purposes, and each has applications for which it is best suited. This denotes that there are differences between them, and these differences can be categorized as the type of lenses used, the resolution of imaging elements, and the underlying software used to interpret the data.
Comic books long have appealed to kids as a fun way to introduce reading and art without being overly didactic. Now a software engineer and project manager from Oklahoma thinks the medium can be used to get them interested in STEM careers.
