    Abstract: A linear movement bistable electromagnetic switch, comprising a coil (1), a magnetic rotor (2) movably disposed in an inner hole of the coil (1), a shell (3) which wraps an outer side surface of the coil (1), and an insulating layer (4) disposed between the coil (1) and the shell (3). The magnetic rotor (2) is able to move under the effect of a magnetic field generated after the coil is energized; one end of the magnetic rotor (2) extends out of the coil (1) and is connected to a blocking piece (211) for opening/closing a loudspeaker leakage hole. The magnetic rotor is able to be extended or retracted by changing the direction of current in the coil so as to drive the blocking piece to block or open the leakage hole, such that the call distortion condition can be improved and the high-frequency sound effect will not be reduced.

  • Patent number: 11951331
    Abstract: Described is an approach for tracking 3D organ motion in real-time using magnetic resonance imaging (MRI). The approach may include offline learning, which may acquire signature and 3D imaging data over multiple respiratory cycles to create a database of high-resolution 3D motion states. The approach may further include online matching, which may acquire signature data only in real-time (latency less than 0.2 seconds). From a motion state and motion signature database, the 3D motion state whose signature best (or sufficiently) matches the newly-acquired signature data may be selected. Real-time 3D motion tracking may be accomplished by performing time-consuming acquisition and reconstruction work in an offline learning phase, leaving just signature acquisition and correlation analysis in an online matching step, minimizing or otherwise reducing latency. The approach may be used to adapt radiotherapy procedures based on tumor motion using a magnetic resonance linear accelerator (MR-Linac) system.

  • Publication number: 20230402729
    Abstract: The present invention provides a retaining component, a battery assembly and an end structure. The retaining component of the present invention is configured to fix multiple cells at the top and/or bottom of the multiple cells, and a hole open to the outside is provided in the retaining component at a position corresponding to a fusible part, so that the fusible part is exposed. According to the present invention, the fusible part can be exposed to the outside at the opening; this provides space for melt-through of the fusible part. For example, when melt-through occurs due to current flow through the fusible part of a collector component, the structure of the opening allows the fusible part to melt through fully, thereby protecting the circuit.
