Abstract: Disclosed are a target speaker separation system, an electronic device and a storage medium. The system includes: first, performing, jointly unified modeling on a plurality of cues based a masked pre-training strategy, to boost the inference capability of a model for missing cues and enhance the representation accuracy of disturbed cues; and second, constructing a hierarchical cue modulation module. A spatial cue is introduced into a primary cue modulation module for directional enhancement of a speech of a speaker; in an intermediate cue modulation module, the speech of the speaker is enhanced on the basis of temporal coherence of a dynamic cue and an auditory signal component; a steady-state cue is introduced into an advanced cue modulation module for selective filtering; and finally, the supervised learning capability of simulation data and the unsupervised learning effect of real mixed data are sufficiently utilized.

Abstract: Techniques are disclosed for cross-polarization-based object detection and classification. One example includes a system implemented for cross-polarization-based object detection and classification. The system includes a first transmitter antenna configured for radiating a first millimeter wave electromagnetic signal, where the first millimeter wave electromagnetic signal including a first polarization. The system further includes a first receiver antenna configured for receiving a second millimeter wave electromagnetic signal, the second millimeter wave electromagnetic signal including a second polarization. The system further includes a processing circuitry configured to detect an object based at least in part on the second millimeter wave electromagnetic signal, the object being impacted by the first millimeter wave electromagnetic signal to cause the second millimeter wave electromagnetic signal to reflect off the object.

Abstract: Disclosed is a postoperative functional exerciser for frozen shoulder. The exerciser includes a hand push rod (1) and a restrictive band (2) for restricting the elbow. The hand push rod (1) comprises a wristband (11) and a push rod (12). One end of the push rod (12) is connected with the wristband (11). When the hand push rod (1) and the restrictive band (2) are in operation, a part of the restrictive band (2) winds around the elbow joint of an affected arm, the other part winds around a waist buckle (3) at a waist portion of the restrictive band (2) on a side opposite to the affected arm, and the wristband (11) is sleeved on the wrist of the affected arm. The upper arm is tied to the body by means of the restrictive band (2).
