摘要:
A method and system for receiving magnetic resonance signals, and a magnetic resonance imaging system are provided. The method includes dividing coil units in a receiving coil array into different coil unit groups. For each of the coil unit groups, correlations are established between carrier frequencies and the signals received by each coil unit in the coil unit group. Low noise amplification is performed, and filtering and frequency mixing is performed on the signals received by all the coil units in the coil unit group according to the correlations to obtain intermediate frequency signals borne on the respectively corresponding carrier frequencies of an identical channel. After performing amplification and filtering on the intermediate frequency signals, the intermediate frequency signals are output to an analog-to-digital conversion unit to perform digital sampling so as to obtain digital domain signals.

Fault of a particular module in an electronic device is detected. In response to detecting the fault, an update module is retrieved from a network site over a network to update the particular module, where the network stack is independent of a network stack associated with an operating system in the electronic device.

Security methods are provided. The method can include comparing a first device identifier (125) disposed within a component (120) with a second device identifier (135) disposed within an immutable memory (130). The component and the immutable memory can be disposed at least partially within an electronic device (110). The method can include starting the electronic device normally if the first device identifier corresponds to the second device identifier. The method can further include providing at least one indicator (150) if the first device identifier fails to correspond to the second device identifier. Security systems are also provided.

A system for a vehicle includes a desired mass air flowrate (MAF) module and a desired effective area module. The desired MAF module generates a desired MAF through a throttle valve of an engine based on an engine torque request. The desired effective area module generates a desired effective area of the throttle valve based on a throttle inlet air pressure (TIAP) and the desired MAF. A throttle actuator module adjusts opening of the throttle valve based on the desired effective area.

A storage device includes storage media and a controller to control access of the storage media. The controller receives an erase command used to specify an erase operation of at least one portion of the storage media. The erase command has a control field controllable by a requestor device that submitted the erase command to the storage device, where the control field has one or more portions settable to cause the storage device to perform one or more of: reporting a progress of the erase operation, and modifying an operational state of the erase operation.

A control system for a hybrid vehicle that includes an internal combustion engine and an electric motor includes an engine speed control module, an air pressure control module, and an engine torque control module. The engine speed control module increases engine speed during a first calibration period based on a driver torque request and a predetermined torque threshold. The air pressure control module decreases intake manifold pressure (MAP) of the engine during a second calibration period based on the driver torque request and the predetermined torque threshold. The engine torque control module starts the engine during a period after the first and second calibration periods by activating N of M cylinders of the engine, wherein N is based on the driver torque request and the predetermined torque threshold.
