By a News Reporter-Staff News Editor at Politics & Government Week -- From Washington, D.C., VerticalNews journalists report that a patent application by the inventors Muggler, Patrick (Palo Alto, CA); Doy, Anthony S. (Los Gatos, CA), filed on September 11, 2012, was made available online on March 20, 2014.

The patent's assignee is Maxim Integrated Products, Inc.

News editors obtained the following quote from the background information supplied by the inventors: "Electronic devices such as smartphones, tablet computers, and so forth, often incorporate touch screen panels for receiving user input. A touch screen panel is a display that can detect the presence, location, or pressure associated with a touch within the display area, such as a finger, hand, stylus, or other pointing device. These touch screen panels may employ piezo components, such as piezoelectric sensors, that are configured to utilize the piezoelectric effect to measure mechanical pressure, acceleration, force, and so forth."

As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventors' summary information for this patent application: "A piezo driver is described that is configured to furnish electric charge to a piezo component and configured to transfer electric charge from the piezo component to a passive energy storage component during various operational states of the piezo driver. In one or more implementations, the piezo driver includes a first passive energy storage component and a second passive energy storage component configured to store electric charge. The piezo driver also includes a voltage converter configured to electrically connect between a piezo component and the first passive energy storage component and the second passive energy storage component. The voltage converter is configured to furnish electric charge from the first passive energy storage component to the piezo component during a first state of operation and to furnish electric charge from the piezo component to the first passive energy storage component during a second state of operation. The voltage converter is also configured to furnish electric charge from the second passive energy storage component to the piezo component during a third state of operation and to furnish electric charge from the piezo component to the second passive energy storage component during a fourth state of operation.

"This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.

"The detailed description is described with reference to the accompanying figures. The use of the same reference numbers in different instances in the description and the figures may indicate similar or identical items.

"FIG. 1A is a block diagram illustrating a piezo driver in accordance with an example implementation of the present disclosure.

"FIG. 1B is a circuit diagram illustrating a piezo driver in accordance with a specific example implementation of the present disclosure.

"FIG. 2 is a flow diagram illustrating a method for at least partially recharging a storage energy component by way of a piezo component within a piezo driver, such as the piezo driver shown in FIGS. 1A and 1B, according to an example implementation of the present disclosure."
