  • Patent number: 11133774
    Abstract: A solar tracking sensor includes lens and four fibers respectively representing four directions installed in a lens barrel to serve as a fine-positioning daylighting module, and four groups of fibers installed on the side of the lens barrel to serve as a coarse-positioning daylighting module. A circuit board and four photocells are installed at the bottom of a cassette. Each photocell is connected to fine positioning fibers located in the same direction as the photocell, and is connected to coarse positioning fibers located in a direction diagonal to the direction of the photocell. By using a daylighting method of combining fine-positioning daylighting and coarse-positioning daylighting, the number of the photocells is reduced, the design of the circuit board is simplified, and costs are reduced; moreover, because the coarse-positioning daylighting module can collect sunlight in a wide-angle range, the tracking angle range of the sensor is enlarged.

  • Publication number: 20210297342
    Abstract: Techniques for utilizing Software-Defined Field-Area Network (SD-FAN) controllers to receive a geographic location and transmission power of individual nodes and generate a geographic location topology of a Field-Area Network (FAN) to provide nodes with location-aware route paths for data transmission. One or more SD-FAN controller(s) may maintain a geographic location database to store the geographic location and transmission power of the individual nodes. Each node may utilize a Destination Address Object to advertise its geographic location and transmission power to the SD-FAN controller. The SD-FAN controller(s) may utilize the geographic location table to generate the geographic location topology of the FAN and determine a location-aware route path for optimized data transmission between nodes in the FAN.

  • Publication number: 20210297076
    Abstract: The present invention discloses a USB signal output circuit having reverse current prevention mechanism. A switch circuit turns on when a switch control terminal receives a first high level voltage to output a signal from a signal input terminal to a signal output terminal. A first voltage pull-low circuit includes a passive-component high-pass filter circuit and a discharging circuit. The passive-component high-pass filter circuit couples an output terminal voltage of the signal output terminal to a pull-low control terminal. The discharging circuit turns on when a voltage of the pull-low control terminal is larger than a predetermined voltage level to discharge the switch control terminal to pull the switch control terminal to a second high level voltage. A second voltage pull-low circuit pulls the switch control terminal to a low level voltage when the output terminal voltage is larger than a reference voltage and does not have a glitch.

  • Publication number: 20210288190
    Abstract: A sensor package structure includes a substrate, a sensor chip disposed on and electrically coupled to the substrate, an opaque support (e.g., a ring-shaped solder mask) disposed on the sensor chip, and a light permeable layer disposed on the opaque support. The sensor chip includes a sensing region. The opaque support surrounds the sensing region, and inner lateral sides of the opaque support form a light-scattering loop wall. The light permeable layer, the light-scattering loop wall of the opaque support, and the sensor chip jointly define an enclosed space therein. When light passes through the light permeable layer and impinges onto the light-scattering loop wall at an incident angle, the light-scattering loop wall scatters the light into multiple rays at angles different from the incident angle.
