Abstract
A mobile device such as a smart phone can be connected to the USB port of a computer such as a laptop to charge the battery of the mobile device and to synchronize data. Also, when a special button is pressed the computer enters a mobile device support mode in which the computer processor does not boot the full service O.S. but only a small O.S., with the mobile device sending demanded images and sounds to the larger display and speakers of the computer and receiving input from the more capable keyboard of the computer so that a user can use the resources of the computer in operating the typically more limited mobile device.
Claims20
Computer comprising:
- at least one processor configured to communicate with at least one mobile device through at least one communication interface;
- at least one computer readable storage medium accessible by the processor and bearing instructions which when executed by the processor configure the processor for:
- responsive to determining that a signal is received indicating mobile device support mode, entering a mobile device 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;
- a display controlled by the processor presents demanded images from the mobile device;
- and,
- wherein 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.
5 more elements
Mobile computing device comprising:
- at least one processor configured to control at least one display in a portable housing;
- communication interface configured to communicate with the processor, the communication interface being configured for data exchange with a computer;
- wherein the processor is configured to execute logic on a storage medium that configures 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 and to receive input signals from a keyboard of the computer for use thereof by the processor of the mobile device;
- and
- wherein responsive to receiving a revocation signal from the computer, the processor when executing the logic is configured to present a message on the display of the mobile computing device indicating demanded images from the mobile computing device will no longer be presented on the display of the computer.
2 more elements
System comprising:
- mobile computing device (MCD) having an MCD processor and MCD display;
- computer having a computer processor and computer display larger than the MCD display;
- communication port on the mobile device;
- communication port on the computer and configured for communication with the communication port of the MCD;
- and
- selector element 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;
- wherein in the mobile device support mode the computer processor of the computer relinquishes control of an internal bus of the computer to the MCD, so that the MCD sends demanded images directly to the computer display of the computer through the communication interfaces without assistance or interference from the computer processor of the computer.
