  • Publication number: 20240405163
    Abstract: A light-emitting diode and a light-emitting device are provided. A transparent conductive layer, a current blocking layer and a first metal reflective layer are sequentially arranged on a side of a second semiconductor layer away from an active layer. A side of the first metal reflective layer adjacent to the current blocking layer is a first Al reflective layer, and metal Al has high reflectivity in a short-wave band, increasing the reflection of light radiated by the active layer. Since there is no need to form an adhesion layer between the first Al reflective layer and the current blocking layer, there is no light absorption problem of the adhesion layer. A projection area of the first metal reflective layer is greater than or equal to that of the transparent conductive layer, so that the first metal reflective layer can cover a larger light-emitting surface, thereby further improving the light reflection.

  • Publication number: 20240378715
    Abstract: The present disclosure provides a method for topography simulation of a physical structure under a topography-changing process. The method includes initializing a voxel mesh as a three-dimensional (3D) representation of a physical structure by a central processing unit (CPU), generating a batch of particles, simulating a flight path of one of the particles with a ray-tracing method by a parallel processing thread in a graphics processing unit (GPU), identifying a surface normal of a voxel unit in the voxel mesh that intersects the flight path by the parallel processing thread in the GPU, passing parameters describing the one of the particles hitting the voxel mesh from the GPU to the CPU, determining a surface reaction between the one of the particles and the voxel unit by the CPU, and updating the voxel mesh based on the determining of the surface reaction.

  • Patent number: 12124433
    Abstract: The present invention relates to an implementation method for graphic-blockchain-orientated hybrid consensus, at least comprising: calling at least one module to generate a new data block and broadcast it; calling at least one module to check and validate the received new block based on predetermined rules; calling at least one module to generate a void block; and calling at least one module to update a committee member list. The existing graphic blockchain can only achieve probabilistic consensus, yet the present invention achieves deterministic consensus on graphic blockchain for the first time, thereby reaching consensus faster. The present invention decouples generation and consensus of blocks for the first time, so that the two parts can be designed separately in a modularized manner. The present invention provides the first totally decentralized hybrid consensus algorithm in the graphic blockchain. This is unachievable to many existing graphic blockchain such as IOTA and Obyte.

  • Publication number: 20230327707
    Abstract: Described are systems, methods, apparatuses, and computer program products for wireless in-ear-monitoring (IEM) of audio. A system includes transmitter(s) configured to map orthogonal sub-carriers of a digital signal to narrowband receivers to form receiver-allocated audio channels, modulate the digital signal, and transmit the signal as an ultra-high frequency (UHF) analog carrier wave comprising the orthogonal sub-carriers to the nearby receiver. A narrowband receiver is configured to demodulate and sample the sub-carriers allocated to the receiver. Sub-carriers can be positioned orthogonal to one another in adjacent sub-bands of the frequency domain and beacon symbols and pilot signals can be iteratively provided in the same portion of the frequency domain for each channel. The receiver can use non-data-aided and data-aided approaches for synchronization of the time domain and frequency domain waveforms of the received signal to the transmitted signal prior to sampling the allocated sub-carriers.
