Hall Effect Sensors are sometimes referred to as “switches” rather than sensors because of the on-off “digital” voltage signal they produce. Unlike magnetic sensors that produce an alternating current (AC) signal which varies in voltage with speed, Hall Effect Sensors produce a constant voltage
signal that can change abruptly from maximum voltage to nearly zero and back again regardless of engine speed. This produces a square wave output signal that can be easily used by the onboard computer for timing purposes.

Lee Products high-flow solenoid valve Active front wings were a feature on F1 cars for the 2010 season but have been banned for the 2011 season, to be replaced by the active rear wing. Drivers are able to control the rear wing once they have been behind another driver for a set amount of time, thereby reducing drag on the straight and allowing greater opportunity for overtaking.
A pinion gear at the pivot, with a rack gear mounted on a rod, driven by a solenoid. This would allow the solenoid to be located lower on the wing endplates, lowering CoG.
DENSO Motor-Driven Electric Variable Valve Timing Control System In place of hydraulic phase shift mechanisms, the Denso system uses an electric motor in the actuator mounted axially with the inlet camshaft that spins faster than the shaft to advance the timing, and slower to retard it. Benefits claimed include better response at low engine speeds and temperatures, positive camshaft positioning for starting, and a greater adjustment range.
The three key components of GM's variable valve timing system are a VVT-specific camshaft, a phaser assembly, and a timing cover with an integrated electric solenoid.

While Formula 1 teams will have to wait until 2014 before they can run the new 1.6 litre V6 engines, one element of the powertrain will make its race debut 12 months earlier. McLaren Electronic Systems has replaced the TAG310B FIA-mandated single ECU with a new, more powerful unit, called the TAG320.
