Graco was founded in 1942 in Philadelphia, Pennsylvania, by Russell Gray and Robert Cone (hence the name) as Graco Metal Products, a company that fabricated machine and car parts. Rex Thomas (one of two engineers hired to come up with a sustainable product) watched his wife sitting on the porch, rocking their baby in a swing with a string tied ...
Graco Inc. is an American industrial company that specializes in the development and manufacturing of fluid-handling systems and products. The company is headquartered in Minneapolis, Minnesota , and markets its products to customers worldwide.
70 years after pulse code cab signals had been introduced, the 4 speed design was found to be insufficient for speeds not envisioned when the system was designed. The two most pressing problems were the use of high speed turnouts , which allowed trains to take a diverging route faster than the normal 30 or 45 mph covered by the existing cab ...
Monopulse radar is a radar system that uses additional encoding of the radio signal to provide accurate directional information. The name refers to its ability to extract range and direction from a single signal pulse. Monopulse radar avoids problems seen in conical scanning radar systems, which can be confused by rapid changes in signal strength.
Pulse 2 is thus counted into the spectral region denoted as P. To ensure pulses are only counted into one channel, the anti-coincidence counter prevents Pulse 1 from being recorded into P . A multichannel analyzer uses a fast ADC to record incoming pulses and stores information about pulses in one of two ways: [ 1 ]
Magnetic pulse welding (MPW) is a solid state welding process that uses magnetic forces to weld two workpieces together. The welding mechanism is most similar to that of explosion welding . [ 1 ] Magnetic pulse welding started [ clarification needed ] in the early 1970s, when the automotive industry began to use solid state welding.
In electronics and telecommunications, pulse shaping is the process of changing a transmitted pulses' waveform to optimize the signal for its intended purpose or the communication channel. This is often done by limiting the bandwidth of the transmission and filtering the pulses to control intersymbol interference .
A digital pattern generator is a piece of electronic test equipment or software used to generate digital electronic stimuli. Digital electronics stimuli are a specific kind of electrical waveform varying between two conventional voltages that correspond to two logic states ("low state" and "high state", "0" and "1").
