Different catheter-based ablation techniques may be used and they generally fall into two categories: (1) cold-based procedures where tissue cooling is used to treat the arrhythmia, and (2) heat-based procedures where high temperature is used to alter the abnormal conductive tissue in the heart.
Speed sensors convert the pulses created by the contact between the magnet and sensor ring through a coil attached to the sensor. This voltage is passed along to the controller. The controller counts the number of pulses to determine wheel speed and evaluates whether the ABS system should intercede to control braking.
How Do Speed Cameras Work? Speed enforcement systems, also known as photo-radar, are triggered when a vehicle exceeding the speed limit by a predetermined amount is observed. Like red light cameras, speed cameras generate photographic evidence that gives the date, time and place, and vehicle speed.
