Operating the computing device on the auxiliary processor draws less power from the computing device battery, enabling extended operation in an auxiliary processor mode. When in this mode, the auxiliary processor controls peripherals and provides the system functionality while the CPU is deactivated, such as in “off,” “standby” or “sleep” modes. In the auxiliary processor mode, the computing device can accomplish useful tasks, such as sending/receiving electronic mail, displaying electronic documents and accessing a network while drawing minimal power from the battery. Transitions between the normal operating mode and auxiliary processor mode may be transparent to users. Such a computer may display instant on, always on and always connected operating features.Type: GrantFiled: August 31, 2009Date of Patent: January 29, 2013Assignee: QUALCOMM IncorporatedInventors: James Pyers, George Wiley, James J.

Patent number: 8359407Abstract: A method and device are provided for activating certain functions of a powered-off device having a serial data bus interface when it is attached to a powered device via the serial bus interface. On detection of a voltage on the power line of the serial bus, the processor of the device is booted in a special operation mode, wherein certain functions of the serial data bus interface can be used without powering the complete device. The device may then be enumerated by the attached host device and for example allow access to its memory unit or use the power signal on the serial bus interface for battery charging.Type: GrantFiled: September 26, 2006Date of Patent: January 22, 2013Assignee: Nokia CorporationInventor: Achim Van Bebber

Patent number: 8359423Abstract: One embodiment of the present invention relates to a method for communicating NOR-type flash specific memory commands from a DRAM memory controller to a NOR-type flash memory array without disrupting DRAM operation. In this embodiment flash specific commands are channeled from the DRAM controller to the flash device by using the DRAM protocol as a transport layer. Data to be written to the NOR-type flash memory array are loaded into a data register and a sequence of programming commands are loaded into a mode register as a series of mode register write operations. Once the entire sequence of programming commands is loaded the NOR-type flash memory array the data in the data register is loaded into the NOR-type flash memory array. Other methods and circuits are also disclosed.Type: GrantFiled: March 14, 2008Date of Patent: January 22, 2013Assignee: Spansion LLCInventors: Stephan Rosner, Qamrul Hasan, Roger Dwain Isaac

Publication number: 20130013818Abstract: The embodiments of the present invention provide a method for switching a working mode, a USB device, and a host device. The method for switching a working mode includes: determining, according to the osvc key value in the registry of a host device, that a driver for a second working mode is installed on the host device, after the USB device is connected to the host device; and switching the current working state of the USB device from a first working mode to the second working mode. In the embodiments of the present invention, neither special auxiliary program nor additional driver needs to be developed. Therefore, the solution is easy to implement and a problem of incompatibility will not occur.Type: ApplicationFiled: September 14, 2012Publication date: January 10, 2013Applicant: Huawei Device Co., Ltd.Inventors: Zhenhui Nie, Yeqi Wang

Patent number: 8352655Abstract: A packet communication device autonomously selects an appropriate operation mode according to a connection environment to an external device before a service of the device is started. When the device is connected to the external buses, connection interface units notify an external device discrimination unit of connection of the device. The external device discrimination unit issues a polling packet to the connected device, discriminates the connected external device on the basis of the response packet, and notifies an operation mode switching unit. The operation mode switching unit selects an operation mode conforming to a connection environment of the packet communication device to the external device and switches the operation mode of the device to the mode.Type: GrantFiled: January 14, 2008Date of Patent: January 8, 2013Assignee: NEC CorporationInventors: Jun Suzuki, Youichi Hidaka, Junichi Higuchi, Shigeyuki Yanagimachi, Takashi Yoshikawa

Patent number: 8332668Abstract: Improved techniques to recognize a power source on a peripheral bus and/or determine power available from the power source via the peripheral bus are disclosed. Typically, the peripheral bus is supported by a cable connected between a host device and an electronic device. In this case, the host device is a power source (e.g., power adapter or battery pack) and the cable is used to provide power from the power source to the electronic device. Hence, by understanding the power available from the power source, the electronic device can manage its power utilization so as to operate in a stable and reliable manner. The electronic device is, for example, a portable computing device. Examples of portable computing devices include a Portable Digital Assistant (PDA) and a portable media player.Type: GrantFiled: January 11, 2011Date of Patent: December 11, 2012Assignee: Apple Inc.Inventors: David John Tupman, Ken Herman, Barry Twycross
