  • Patent number: 11226857
    Abstract: When the inspection unit corresponding to at least one disabled layer of a multilayer system is unavailable, a fault-eliminating device defines the at least one disabled layer and a target layer as a combined layer. The fault dependency of the target layer is the lowest among the fault dependency of the at least one available layer. The inspection unit of the at least one available layer is active and the fault dependency thereof is higher than the disabled layer. Then, the device makes the inspection unit and the fault symptom corresponding to the target layer correspond to the combined layer, so as to update a list of layers and a fault model. After that, the device determines a source of a fault from the layers according to the list of layers and the fault model, and performs a strategy of fault elimination corresponding to the source, to eliminate the fault.

  • Patent number: 11176112
    Abstract: An apparatus of adaptive index structures is provided. Four common data attributes, including time, space, keyword, and value, are used. The present invention is a structure adaptively selecting the most efficient combined index by estimating index performance and selectivity rate. The main concept is to set indexes with high selectivity rates at positions having higher priorities for processing query. The intermediate result of query is minimized and the performance is further improved. The present invention uses multiple indexes, where all possible combined-index orders are considered and the best combined index is selected according to different query adaptabilities. As a result, the structure has a high chance of saving query time at a rate of more than 25 times as compared to a structure with indexes of a single attribute sequence. Furthermore, as compared to the traditional relational database PostGIS, the reaction time is also twice faster.

  • Patent number: 11101399
    Abstract: A single-photon detector is provided. The detector has multiple avalanche layers. It has an avalanche photodiode (APD) structure using single photon. The APD is made of indium aluminum arsenide (InAlAs). At least two avalanche layers are designed. When the layer for avalanche is numbered only one and the gain is very big, the speed will be deteriorated very quickly. With the design of two avalanche layers in the present invention for the very big gain, the speed deterioration can be suppressed. After measuring, the present invention shows a faster speed as compared to prior arts. It proves that, by using more than two avalanche layers, the present invention effectively improves the feature of single-photon detector. Hence, the present invention is especially suitable for single-photon detection.

  • Patent number: 11056604
    Abstract: An avalanche photodiode (APD) is provided with a mixed composite charge layer. A novel structure of InAlAs is designed with the mixed layer. A single P-type field control layer is divided into three layers of different materials with each two forming a heterojunction structure. By controlling the relative concentration distributions and thicknesses of the first, second, and third P-type field control layers along with a mesa shape formed through chemical selective etching, a part of the second P-type field control layer is exposed to the air with a part of the first one etched out at the same time through this single structure having the mesa shape. Thus, the field of a multiplication layer is further confined at center to concentrate electric-field so that fringe field is low but not collapsed. Hence, the overall speed is increased, the intensity high, and sensitivity good while response is fast and efficiency high.
