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.
Some vehicles use seperate sensors for the ABS, but it is common that the computer uses the information from the wheel sensors to act as a VSS. For example, many newer Ford vehicles use a rear axle mounted speed sensor for both ABS and computer related vehicle speed functions. Instrument Cluster (IC) and Hybrid Electric Cluster (HEC) modules use vehicle speed info for speedometer operation.
