Patent Issued for System for Displaying Image from Mobile Device on a Display in a Computer by Booting the Computer with Limited Operating System and Relinquishing Bus Control to the Mobile Device

By a News Reporter-Staff News Editor at Computer Weekly News -- Sony Corporation (Tokyo, JP) has been issued patent number 8819402, according to news reporting originating out of Alexandria, Virginia, by VerticalNews editors.

The patent's inventor is Tran, Teresa (San Diego, CA).

This patent was filed on July 6, 2011 and was published online on August 26, 2014.

From the background information supplied by the inventors, news correspondents obtained the following quote: "An increasing number of people are beginning to use mobile operating systems on small mobile computers such as so-called smart phones, tablet computers, and personal digital assistants (PDAs) for their primary computing needs. These products offer much flexibility when using portable applications, playing casual games, and for viewing and listening to multimedia content. However, as understood herein most of these devices have a small screen, tiny speakers, and no physical input device other than a touch screen. Also, many of these same users possess a more capable computer system such as a PC-like computer such as a notebook computer which functions to transfer data back and forth between the two devices as well as to charge the mobile product.

"As understood herein, there can be times when a user of a small mobile computer doesn't need to use a PC device at all, but nonetheless desires a larger screen, better sound, and easier input for the mobile device. Unfortunately, simple docking systems for mobile computers for the most part do no more than charge the mobile computer and synchronize data between the mobile computer and the PC-like computer."

Supplementing the background information on this patent, VerticalNews reporters also obtained the inventor's summary information for this patent: "Accordingly, a computer such as a laptop or desk top computer includes a housing, a display on the housing, a communication interface such as a universal serial bus (USB) port, and a processor in the housing communicating with a mobile device through the communication interface. The processor executes logic including, responsive to determining that a signal is received indicating mobile device support mode, entering a mobile support mode in which the processor does not boot a full service operating system (O.S.) into memory and instead executes a limited O.S. The processor sends a permission signal to the mobile device indicating that the mobile device support mode is active, and this permission signal may be presented on the display of the mobile device informing the user of expanded capabilities afforded by the computer. The display presents demanded images from the mobile device, and responsive to determining that a signal is received indicating mobile device support mode is suspended, the processor leaves the mobile support mode and boots a full service O.S. into memory.

"If desired, the mobile device support mode is entered only responsive to determining that a signal is received indicating mobile device support mode and also determining that the mobile device is connected to the communication interface. In some embodiments, responsive to detection of the mobile device connection at the communication interface, the computer causes charge current to flow through the communication interface to charge a battery of the mobile device, and data is synchronized between the computer and the mobile device.

"In example implementations, in the mobile device support mode the processor receives demanded images from the mobile device and controls the display to present the demanded images. In other embodiments, however, in the mobile device support mode the processor relinquishes control of an internal bus of the computer to the mobile device, so that the mobile device sends demanded images directly to the display through the communication interface without assistance or interference from the processor.

"If desired, in the mobile device support mode the computer provides to the mobile device access to at least a data storage in the housing. Also, in the mobile device support mode, commands input using a keyboard of the computer may be sent to the mobile device through the communication interface. Responsive to determining that a signal is received indicating mobile device support mode is suspended, the processor can send to the mobile device a revocation signal informing the mobile device that the mobile device support mode is suspended. The signal can be presented on the display of the mobile device.

"In another aspect, a mobile computing device such as a smart phone has a processor in a portable housing, a display on the housing, and a communication interface on the housing communicating with the processor. The communication interface is configured for data exchange with a computer. The processor executes logic on a storage medium that causes the processor, responsive to a determination that a permission signal is received from the computer, to send demanded images through the interface to the computer for presentation of the demanded images on a display of the computer. The processor also receives input signals from a keyboard of the computer for use thereof by the processor of the mobile device.

"In another aspect, a system includes a mobile computing device (MCD) having an MCD processor and MCD display and a computer having a computer processor and computer display larger than the MCD display. A communication port is on the mobile device and likewise a communication port is on the computer and is configured for communication with the communication port of the MCD. A selector element is manipulable by a person to cause the computer processor to enter a mobile device support mode in which the computer processor does not boot into memory a full service operating system (O.S.) contained on a hard disk drive of the computer and the MCD presents demanded images on the computer display of the computer.

"The details of the present invention, both as to its structure and operation, can best be understood in reference to the accompanying drawings, in which like reference numerals refer to like parts, and in which:
