    摘要: Apparatus and methods are presented for protecting data in microcontrollers from both malicious software processes running inside the device as well as from unauthorized attempts to read the data from an external data bus and/or external memory. An illustrative embodiment of the invention accomplishes these security improvements, in part, by utilizing an enhanced memory management unit (MMU). The enhanced MMU is configured to prevent one software process running on the microcontroller from accessing data associated with a different software process running on the same microcontroller. Moreover, data transmitted over an external data bus or stored in an external memory is encrypted, thereby reducing the chances that unauthorized users will gain exploitable information from this data.

    摘要: The present invention provides a mobile portable device comprising a network communication module, a power-on circuit, a switching power supply, a system power supply and external battery and a calculation unit, wherein the system power supply and external battery constantly supply power to the network communication module by using an external AC power supply or the power of the battery, when the mobile portable device is in a power-off/sleep state, and when the power-on circuit detects that the network communication module has received information from a network, it activates the switching power supply to supply power to the mobile portable device and thus put the mobile portable device into an operating state. By supplying power to the network communication module in the power-off/sleep state of the notebook computer, the computer can be in the network communication state at any time and thus will not miss any information transmitted over the network.

    摘要: A MRI guided high-intensity focused ultrasonic therapeutic system comprises: a MRI apparatus and a high-intensity focused ultrasonic therapeutic apparatus. Said MRI apparatus includes the first treatment bed and said high-intensity focused ultrasonic therapeutic apparatus includes an ultrasound transducer and a moving and positioning means, which drives said transducer to move in respective directions. Wherein, said moving and positioning means is placed outside of the bore of the MRI apparatus during treatment and a supporting rod, which can extend into the bore of the MRI apparatus, is connected to said moving and positioning means at one end and is connected to said ultrasound transducer at the other end. In the system provided by the present invention, said ultrasound transducer can move in multiple orientations, freely move without any limitation of space under the treatment bed, brings less interference to the MRI apparatus, fully exerts the function and efficiency of the MRI apparatus and achieves the best therapeutic effects.
