Effect of transcutaneous acupoint electrical stimulation
For each epoch, (1) Perform the Morlet wavelet transform with the wavelet central angle frequency of 6 (ω0 = 6) at frequency band 2.0 Hz to 45 Hz, with a frequency resolution of 0.5 Hz; (2) EEG could have little chance of sudden change during anesthesia. Therefore, we reasonably treat the abrupt change in EEG energy as induced by artifacts.

Electrosurgery - an overview | ScienceDirect Topics
Mark E. Bruley, in Complications in Head and Neck Surgery (Second Edition), 2009 Electrosurgery. Electrosurgery is a widely used surgical technology that employs a high-frequency electric current passing through tissue to cut or cauterize that tissue. ESUs are the most common ignition source in surgical fires. 5, 9 By its very nature, electrosurgery can produce a high …
Insulation Testing Key to Reducing Electrosurgery Risks in
· A laparoscopic insulation tester is a low-frequency, high-voltage generator that delivers the voltage to an inspection electrode. As the electrode moves over the insulation and a pin hole or bare spot is encountered, a small current flow will create a visible (non-hazardous) spark at the point of contact, which then triggers a visible and .

Ram 1500 Spark Plug & Ignition Wires – CARiD.com
Spark plug wires are necessary for the transfer of electrical impulses from the ignition coil(s) to the spark plugs. These high-voltage impulses appear with high frequency and must be strong enough when they reach a spark plug. In order to operate perfectly, the wires must have good conductivity and isolation.
