Tic
Complex motor tics are typically more purposeful-appearing and of a longer nature. They may involve a cluster of movements and appear coordinated. Examples of complex motor tics are pulling at clothes, touching people, touching objects, echopraxia (repeating or imitating another person's actions) and copropraxia (involuntarily performing obscene or forbidden gestures).
Motorcycle Stability Control
Motorcycle Stability Control (MSC) is a motorcycle electronic brake control system developed by Robert Bosch GmbH. It is a lean-sensitive variation of the traditional ABS system Anti-lock braking system. The MSC system uses accelerometers and/or gyroscopic sensors to evaluate how close to the limit of adhesion the motorcycle is cornering. It reduces the allowable braking tire slip ratio, reducing the braking force, thus preventing the tire skid, and keeping the motorcycle from falling into the turn, or low-siding.
