  • Patent number: 12210952
    Abstract: A reorganizable neural network computing device is provided. The computing device includes a data processing array unit including a plurality of operators disposed at locations corresponding to a row and a column. One or more chaining paths which transfer the first input data from the operator of the first row of the data processing array to the operator of the second row are optionally formed. The plurality of first data input processors of the computing device transfer the first input data for a layer of the neural network to the operators along rows of the data processing array unit, and the plurality of second data input processors of the computing device transfer the second input data to the operators along the columns of the data processing array.

  • Patent number: 9658302
    Abstract: A method of synchronizing clocks between a central controlling unit and a radio frequency (RF) coil which are wirelessly connected to each other in a magnetic resonance imaging (MRI) system, which includes receiving a first clock from the central controlling unit, synchronizing a second clock of the RF coil with a received first clock, and discontinuing the receiving of the first clock from the central controlling unit when the second clock is synchronized with the first clock.

  • Patent number: 9229075
    Abstract: A magnetic resonance imaging (MRI) system includes a radio frequency (RF) coil which receives timing information about a pulse sequence and stores the timing information in a memory of the RF coil. Then, when an RF excitation signal is transmitted, the RF coil performs decoupling. When a magnetic resonance (MR) echo signal is generated, the RF coil receives the MR echo signal and transmits the MR echo signal to a central controlling apparatus through a wireless channel. When a transmission error arises, the RF coil retransmits corresponding data in an idle time when the RF excitation signal is not transmitted or the MR echo signal is not generated. Thus, the RF coil is prevented from being damaged by the RF excitation signal and prevents the quality of an MR image from deteriorating compared to a synchronization-type communication method.
