US Patent:

20060112296, May 25, 2006

Filed:

Nov 5, 2004

Appl. No.:

10/983237

Inventors:

Thomas Sheahan - Cary IL, US
Keith Kolmos - Elgin IL, US
Raymond Altenburger - Bartlett IL, US

International Classification:

G06F 11/00

US Classification:

714002000

Abstract:

An improved data recovery system for appliances is provided. The system includes an operating module with operating memory which controls the appliance, a recovery module which recovers operation of the device upon a power disturbance, and a data storage device. During operation, critical data is saved to the data storage device. In the event of a power disturbance causing the operating module to reset, the data storage device is checked for valid saved critical data which, if found, is loaded into the computing device's operating memory upon power restoration. In this way, the system is able to recover operation from the point at which critical data was last saved, without the use of a power loss detection circuit and large capacitor used in traditional systems to detect power loss, and power the system while critical data is saved.

Abstract:

A fan having one fan blade; a fan motor for rotating the fan blade; a motor control electrically coupled with the fan motor for controlling operational characteristics of the fan motor; and a power supply having a step-down high efficiency buck converter, a step-down low drop-out linear regulator, and/or a step-down switching regulator are described. The power supply may receive a first input voltage and lower the first input voltage to a second lower voltage. The fan motor is electrically coupled to be driven by the first input voltage and the motor control is electrically coupled to operate using the second lower voltage from the power supply. The motor control may include a microcontroller, level shifters electrically coupled to the microcontroller, and drivers electrically coupled to the level shifters and configured to drive the fan motor.
