Patent number: 10164444Abstract: An energy storage device includes an integrated fuel gauge that is operatively connected to the energy storage device. The fuel gauge evaluates an operating parameter of the energy storage device and dynamically determines a state of charge. The fuel gauge communicates a communication including a requested operating parameter to the charging component with the single communication line and the signal indicates to an operating system component a change of an energy storage device state. The signal is used to trigger an alert or interrupt that causes the operating system component to display the change of the energy storage state based on the signal.Type: GrantFiled: June 6, 2017Date of Patent: December 25, 2018Assignee: Hewlett-Packard Development Company, L.P.Inventors: Thomas P. Sawyers, Jon G. Lloyd, John Wozniak, Christopher K. Matthews

Patent number: 10084316Abstract: One example of a device includes an output terminal to electrically couple to a load, a first input terminal to electrically couple to a first voltage source, and a blocking rectifier electrically coupled between the first input terminal and the output terminal. The device includes a second input terminal to electrically couple to a second voltage source. The second input terminal is electrically coupled to the output terminal. The device includes a control circuit to control the second voltage source to prevent a voltage at the output terminal from exceeding a voltage at the first input terminal and to deliver power to the load in place of power delivered by the first voltage source.Type: GrantFiled: January 31, 2014Date of Patent: September 25, 2018Assignee: Hewlett-Packard Development Company, L.P.Inventor: Thomas P Sawyers
