  • 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.

  • POWER SYSTEM
    Publication number: 20240154447
    Abstract: A power system including a first battery pack, a second battery pack, and a power management circuit is disclosed. The first battery pack has a first end and a second end, and has a first battery capacity. The second battery pack has a third end and a fourth end. The third end is coupled to the second end of the first battery pack and provides a low battery voltage. The fourth end is grounded, the second battery pack has a second battery capacity, and the second battery capacity is greater than the first battery capacity. The power management circuit is coupled to the second battery pack to receive the low battery voltage, and provides a component operating voltage to an electronic components based on the low battery voltage.

  • XDSL and G.Fast SFP for any-PHY platform
    Patent number: 9866257
    Abstract: A transceiver in the form of an integrated small form-factor pluggable (SFP) module is described. The SFP module may include a processor, a hybrid circuit, a transformer, a RJ45 connector and a SFP connector. The processor may be configured to perform functions as a serializer/deserializer (SerDes), a digital signal processor (DSP), an analog front-end and a line driver. The hybrid circuit may be configured to neutralize signals reflected from a transmit direction to a receive direction. The DSP may be configured to support communication according to a Very-high-bit-rate Digital Subscriber Line (VDSL) technology such as the G.Fast standard.
