Abstract: A backup power supply includes at least one ultra capacitor to store energy. The backup power supply includes a multiphase boost converter to provide a relatively constant voltage level from the energy stored on the at least one ultra capacitor. A charging and discharging controller is used to monitor the status of a power supply and control the charging and discharging of the ultra capacitors.

Abstract: A device, system and method for a backup power supply are disclosed herein. The backup power supply may use at least one ultra capacitor to store a voltage. The backup power supply may also have a multiphase boost converter to provide a relatively constant voltage from the stored voltage and a constant changing power filter to regulate a current that is used to charge the ultra capacitor. A charging and discharging controller may be used to monitor the status of a power supply and control the charging and discharging of the ultra capacitors.

Abstract: The disclosed embodiments are directed to an improved automatic screw machine employing a first servomotor connected to cause rotation of a first set of tooling cams independently of the operation of a spindle drive, and a second servomotor to cause rotation of a second set of cams independently of the operation of the spindle drive, wherein a multi-axis controller controls at least the speed of the spindle drive in conjunction with at least each of the two servomotors, and where the operation of at least the two servomotors is electronically synchronized.
