  • Optical element driving mechanism having movable portion for holding lens
    Patent number: 11982866
    Abstract: An optical element driving mechanism is provided and includes a fixed assembly, a movable assembly, a driving assembly and a stopping assembly. The fixed assembly has a main axis. The movable assembly is configured to connect an optical element, and the movable assembly is movable relative to the fixed assembly. The driving assembly is configured to drive the movable assembly to move relative to the fixed assembly. The stopping assembly is configured to limit the movement of the movable assembly relative to the fixed assembly within a range of motion.

  • TARGET DETECTION METHOD, TARGET DETECTION DEVICE, AND MILLIMETER WAVE RADAR SYSTEM
    Publication number: 20240061095
    Abstract: A target detection method includes generate a frequency modulated continuous wave (FMCW) signal; send the FMCW signal through a radar module; receive a first echo signal and a second echo signal reflected by a target and respectively corresponding to a first output signal and a second output signal; process the first echo signal and the second echo signal to correspondingly obtain a first time domain signal S(t1) and a second time domain signal S(t2); process the first time domain signal S(t1) and the second time domain signal S(t2) to obtain a differential time domain signal ?S(t) which satisfies ?S(t)=S(t2)-S(t1); convert the differential time domain signal ?S(t) into an intermediate frequency (IF) signal through Fast Fourier Transform (FFT); calculate a relative distance or a relative velocity of the target relative to the radar module based on the IF signal.

  • Combined Structure of Waterproof Lens and Camera for Monitoring Purpose
    Publication number: 20110064395
    Abstract: A combined structure of waterproof lens and waterproof camera for rapid and simple assembly and disassembly; it comprising: waterproof lens and waterproof camera; in particular: the locking portions, such as internal thread and groove, are arranged onto the hollow wall of a socket end of the waterproof lens, while snapping portions, such as external thread and retaining clip, are arranged around an embedding end of the waterproof camera; based on this structural design, the waterproof lens and waterproof camera can be combined easily by the matched locking portions and snapping portions, thus realizing rapid separation for subsequent efficient repair, maintenance and replacement.
