  • Publication number: 20250146868
    Abstract: A microscopic confocal fluorescence spectrometer is provided. The microscopic confocal fluorescence spectrometer includes an optical system and an instrument body. By adopting an open microscopic fluorescence light path, a lens body part of an existing spectrometer microscope is omitted, so that the space behind an objective lens is significantly increased. By reasonably arranging a laser, a spectrum detection device and other components, the space on the side of the objective lens is further increased, and the occupied space of the optical system is reduced, so that the overall volume of the instrument is reduced, and the adaptability of the instrument is further improved. In addition, the spectrum detection device is arranged outside the second shell to facilitate the heat dissipation of the spectrum detection device, so that the heat stability and working reliability of the instrument are further improved.

    Abstract: A speaker includes housing having receiving space and sound-producing unit received in receiving space. The sound-producing unit includes frame; vibration unit; magnetic circuit unit; spring damping element elastically connects magnetic circuit unit to frame and supports magnetic circuit unit to vibrate in accommodating space. A weight is fixed to magnetic circuit unit. In speaker, magnet or yoke and spring damping element form another vibration unit. This another vibration unit and the vibration unit that is composed of voice diaphragm, dome, and voice coil are subjected to interaction forces and vibrate in opposite directions, which reduces force on frame. The weight is added to magnetic circuit unit, which reduces the impact of air in rear cavity on magnet. Moreover, by adjusting mass of weight and stiffness and damping of spring damping element, corresponding resonant frequency and damping of magnetic circuit unit may be set, thereby achieving an optimal vibration isolation effect.

  • Publication number: 20250103404
    Abstract: An approach for managing log messages. In this approach, a hierarchical structure identifies primary and secondary relationships between the log messages. In this approach, primary log messages in the log messages that has one or more secondary log messages is identified using the hierarchical structure. One or more pointers are added to each primary log message in the log messages having the one or more secondary log messages. Each pointer points to a secondary log message in the hierarchical structure. The one or more secondary log messages are removed from the log messages to form remaining log messages. Header information from log message headers and content information from log message content in the remaining log messages are saved to form compressed log information.

  • Patent number: 12236983
    Abstract: Various systems and methods are presented regarding interrupting a write operation to enable a read operation to be performed on a digital tape system. An initial write operation to the tape can be paused, a read operation performed on a previously written data file conducted, and upon completion of the read operation, the write operation can be recommenced. Interrupt points can be positioned within respective data blocks. Based upon knowledge of the amount of data written during the initial write operation, a position P can be determined (relative to the location of the nearest prior interrupt point) such that when the tape is advanced to place the tape head in a position to recommence the write operation after the read operation has been performed, the tape can be positioned such that the tape head is at position P. Accordingly, interruption of the write operation enables random access of the tape.

  • Patent number: 12192730
    Abstract: A multifunctional sound device includes a housing, a sound unit, a vibrator, and a coil. The housing includes an accommodating cavity, and the sound unit is suspended in the accommodating cavity. The sound unit includes a frame, a vibration system, and a magnetic circuit system. The vibration system is fixed in the frame, and the magnetic circuit system drives the vibration system to vibrate and generate sound along a first direction, where the magnetic circuit system includes a magnetic gap. Since the speaker and the motor share one magnetic system, the sound unit and the vibrator are assembled in the housing, which greatly reduces occupied space.
