Abstract: A local coil control apparatus and a wireless local coil in a magnetic resonance imaging system. The apparatus includes a control signal transmission unit, the control signal transmission unit including a wireless receiving unit, a control signal extraction unit, and a control signal distribution unit. The wireless receiving unit receives, by a receiving antenna, a signal from a radiofrequency power amplifier emitted by a body coil of the MRI system, and transmits the signal to the control signal extraction unit; the control signal extraction unit, if it detects that the signal is background noise, generates a control signal instructing a local coil unit to switch to a tuned state, and, if it detects that the signal is broadband noise, generates a control signal instructing the local coil unit to switch to a detuned state, and distributes the control signal to each local coil unit through the control signal distribution unit.

Abstract: A system and method for reverberation reduction is disclosed. A first Deep Neural Network (DNN) produces a first estimate of a target direct-path signal from a mixture of acoustic signals that include the target direct-path signal and a reverberation of the target direct-path signal. A filter modeling a room impulse response (RIR) for the first estimate is estimated. The filter when applied to the first estimate of the target direct-path signal generates a result closest to a residual between the mixture of the acoustic signals and the first estimate of the target direct-path signal according to a distance function. The estimated filter is used for modeling the RIR.

Abstract: A system and method for reverberation reduction is disclosed. A first Deep Neural Network (DNN) produces a first estimate of a target direct-path signal from a mixture of acoustic signals that include the target direct-path signal and a reverberation of the target direct-path signal. A filter modeling a room impulse response (RIR) for the first estimate is estimated. The filter when applied to the first estimate of the target direct-path signal generates a result closest to a residual between the mixture of the acoustic signals and the first estimate of the target direct-path signal according to a distance function. A mixture with reduced reverberation of the target direct-path signal is obtained by removing the result of applying the filter to the first estimate of the target direct-path signal from the received mixture. A second DNN produces a second estimate of the target direct-path signal from the mixture with reduced reverberation.

Abstract: A system and method for low-latency audio signal enhancement is provided. An input mixture of audio signals is partitioned into a sequence of overlapping frames by using a first sliding window method. The first sliding window method comprises a first window function having a first width associated with a window of the corresponding frame and a shift length associated with shifting of the window of the first sliding window method. Each frame is then processed using a first DNN, a frequency domain causal linear filter and a second DNN, to generate final enhanced overlapping frames for each of the processed frames. The final enhanced overlapping frames are then combined using a second sliding window method associated with a second window function having a second width less than the first width and the same shift length as the first sliding window method.

Abstract: A rooftop shelter that can be mounted to a roof of a vehicle and can be quickly and readily assembled and disassembled. The rooftop shelter includes a body and a hinged cover that resembles a suitcase. A roof panel is pivotally coupled to the hinged cover. A left wall panel, a right wall panel, and a front wall panel can be coupled to three respective sides of the body. The body and the hinged cover in the folded state can encase the above four panels. The rooftop shelter can be set up by unfolding the hinged cover and the four panels, wherein the body, hinged cover, roof panel, left panel, right panel, and front panel together form an enclosure. This same structure can use for quick movable ground shelters.

Abstract: A system and method for detecting anomalous sound are disclosed. The method includes receiving a spectrogram of an audio signal with elements defined by values in a time-frequency domain of the spectrogram. Each of the values corresponds to an element of the spectrogram that is identified by a coordinate in the time-frequency domain. The time-frequency domain of the spectrogram is partitioned into a context region and a target region. The context region and the target region are processed by a neural network using an attentive neural process to recover values of the spectrogram for elements with coordinates in the target region. The recovered values of the elements of the target region are compared with values of elements of the partitioned target region. An anomaly score is determined based on the comparison. The anomaly score is used for performing a control action.
