Adaptive Pulse Width Modulation
2004Many spacecraft attitude control systems use actuators that operate in an on-off mode; typical examples are the jet thrusters, for which the control amplitude cannot be modulated. Moreover, if we want to reduce the complexity of the devices that drive the actuators, as for example in the case of magnetic coils, the on-off input is the simplest signal ...

Accelerometer with pulse width modulation
The Journal of the Acoustical Society of America, 1992An accelerometer having a movable electrode which is moved according to acceleration with respect to a fixed electrode disposed in opposition to the movable electrode. An output device generates an output voltage which is proportional to the acceleration by measuring a gap between the movable electrode and the fixed electrode.

Sequential Pulse Width Modulated Shunts
2003In the previous chapter, a major concern was raised regarding the power dissipation of linear shunt dissipation elements; shunt transistors and resistors. Basically, it is the thermal environment those elements generate that is the main concern. It was also mentioned in section 7.3 that by taking the advantage of the short circuit operating point of ...
