Editor's Note: Low-cost, easy-to-use development systems lower the threshold to entry into embedded systems development for engineers, regardless of their experience level. Among these compact ...

Multiple methods are available to monitor the health of a power supply, ultimately leading to improved reliability of the power subsystem and, subsequently, the total system. These improvements can ...

Two new Apple patents involving a PWM and a data transformation system have appeared at the US Patent & Trademark Office. Patent number 20110254464 involves a pulse width modulation (PWM) closed loop ...

This circuit transforms a pulse-width-modulation (PWM) signal into non-overlapping clock signals, whose number depends on the length of a shift register. These clock signals can be used to power up ...

Withclosed loop speed control, the fan controller ensures that the fan isrunning at the desired speed by measuring the actual speed and adjustingthe duty cycle accordingly. Here the host specifies the ...
