  • Publication number: 20220342051
    Abstract: Disclosed are a TOF depth sensing module and an image generation method. The TOF depth sensing module includes an array light source, a beam splitter, a collimation lens group, a receiving unit, and a control unit. The array light source includes N light emitting regions. The collimation lens group is located between the array light source and the beam splitter. The control unit is configured to emit light. The collimation lens group is configured to perform collimation processing on beams. The beam splitter is configured to perform beam splitting processing on beams. The receiving unit is configured to receive reflected beams of a target object. By means of the TOF depth sensing module, high spatial resolution and a high frame rate can be implemented in a process of scanning the target object.

  • Patent number: 11409344
    Abstract: A head-mounted heat dissipation device includes a fan assembly and a wearing assembly. The wearing assembly is connected to the fan assembly to fix the fan assembly onto a head of a user. The fan assembly includes a casing and fans arranged in the casing. Air inlets and air outlets are defined in the casing. The air outlets are located on an inner side of the bottom surface of the casing, so that the air from the air outlets can be blown to the user's face. In addition, air guide strips are arranged side by side on a side of the air outlet within the casing for concealing the operation of the fans.
