Makita Auto-Start Wireless System (AWS) is a wireless communication method used between power tools and dust collection devices/vacuum cleaners, released by Makita in 2017. [ 24 ] The system uses Bluetooth Low Energy (BLE).
Makita circular saw. Makita Corporation (株式会社マキタ, kabushiki gaisha Makita) (TYO: 6586) is a Japanese manufacturer of power tools.Founded on March 21, 1915, it is based in Anjō, Japan and operates factories in Brazil, China, Japan, Mexico, Romania, the United Kingdom, Germany, United Arab Emirates, Thailand, Indonesia, Malaysia, Philippines, Canada, and the United States.
The AWS visual indicator ('sunflower') in the driver's cab will change to all black. If the signal being approached is displaying a 'clear' aspect, then AWS will sound a bell tone (modern trains have an electronic sounder that makes a distinctive 'ping') and leave the 'sunflower' black.
(The nominal power of the transmitter.) The blanking level (300 mV) yields 73% (in an ideally linear transmitter). Usually the figure 75% is found to be acceptable. The highest modulating signal at white (1000 mV) yields only 10% of the carrier. (so called residual carrier). Sometimes 12.5% is used as the residual carrier so the output power ...
The transmitter oscillator drives the transmitter plates in opposite phase (180° phase difference) by a high alternating voltage, and the load is connected between the two receiver plates. The alternating electric fields induce opposite phase alternating potentials in the receiver plates, and this "push-pull" action causes current to flow back ...
Battery consumption of the phones is a factor that must be taken into account when deploying beacon enabled apps. A recent report has shown that older phones tend to draw more battery power in the vicinity of iBeacons, while the newer phones can be more efficient in the same environment. [ 10 ]
A radio transmitter or just transmitter is an electronic device which produces radio waves with an antenna. Radio waves are electromagnetic waves with frequencies between about 30 Hz and 300 GHz. The transmitter itself generates a radio frequency alternating current, which is applied to the antenna. When excited by this alternating current, the ...
AWS/TPWS acknowledgement button. TPWS temporary isolation switch. AWS/TPWS full isolation switch. If the loops are energised, an aerial on the underside of the train picks up the radio frequency signal and passes it to the receiver. A timer measures how long it takes to pass between the arming and trigger loops.
