Heart rate is measured by finding the pulse of the heart. This pulse rate can be found at any point on the body where the artery's pulsation is transmitted to the surface by pressuring it with the index and middle fingers; often it is compressed against an underlying structure like bone. The thumb should not be used for measuring another person ...
Pulse watches are also heavily used in the sport and exercise industry. Coaches and health professionals may want to monitor and analyse an athlete's physical activities. [18] A clinical review found that the use of wearable devices in athlete monitoring, has a significant impact on the improvement of performance. [19]
These may include sensors such as accelerometers, gyroscopes, and GPS to detect speed, location and distance. [3] In recent years, it has been common for smartwatches to include heart rate monitors, which has greatly increased in popularity. [4] Some smartwatches, smart bands and cell phones often use PPG sensors. [5]
A pulse oximeter probe applied to a person's finger. A pulse oximeter is a medical device that indirectly monitors the oxygen saturation of a patient's blood (as opposed to measuring oxygen saturation directly through a blood sample) and changes in blood volume in the skin, producing a photoplethysmogram that may be further processed into other measurements. [4]
Simple bench pulse generators usually allow control of the pulse repetition rate , pulse width, delay with respect to an internal or external trigger and the high- and low-voltage levels of the pulses. More sophisticated pulse generators may allow control over the rise time and fall time of the pulses. Pulse generators are available for ...

For example, an IBM PC with an Intel 80486 CPU running at 50 MHz will be about twice as fast (internally only) as one with the same CPU and memory running at 25 MHz, while the same will not be true for MIPS R4000 running at the same clock rate as the two are different processors that implement different architectures and microarchitectures ...
