  • Patent number: 11183568
    Abstract: Disclosures of the present invention mainly describe a two-dimensional semiconductor device (TDSD), comprising: a two-dimensional semiconductor material (TDSM) layer, a superacid action layer and a superacid solution. The TDSM layer is made of a transition-metal dichalcogenide, and the superacid action layer is formed on the TDSM layer. Particularly, an oxide material is adopted for making the superacid action layer, such that the superacid solution is subsequently applied to the superacid action layer so as to make the superacid solution gets into the superacid action layer by diffusion effect. Experimental data have proved that, letting the superacid solution diffuse into the superacid action layer can not only apply a chemical treatment to the TDSM layer, but also make the TDSD have a luminosity enhancement. Particularly, the luminosity enhancement would not be reduced even if the TDSD contacts with water and/or organic solution during other subsequent manufacturing processes.

    Abstract: A system and method for locating a traffic light at a host vehicle. A probe vehicle obtains image data on an intersection that includes the traffic light when the probe vehicle is at the intersection and identifies the traffic light in the intersection from the data. A remote processor creates an observed node in a digital map corresponding to the traffic light and updates a mapped position of a mapped node within the digital map based on an observed position of the observed node. The host vehicle uses the mapped node of the digital map to locate the traffic light when the host vehicle is at the intersection.

  • Patent number: 10909074
    Abstract: Embodiments provide a method to collect aggregate information or usage data quickly and efficiently with minimal lag. Additionally, the system can use this aggregate information internally for improved load balancing, better data placement, optimization, and enhanced debugging. The system can quickly look at aggregate information across a huge amount of data and drill down cheaply because the aggregate information is generated using existing processes. Aggregated statistics storage and collection may be built on top of an LSM tree used to store a persistent index for a cloud storage system. The statistics may also represent the result of an operation (e.g., max, min, sum, average) on selected parameter(s) or attribute(s) of stored data. Aggregate statistics values may be efficiently maintained during index merge and garbage collection processes or any other index management. As delta LSM trees are merged into a base LSM tree, the aggregates are updated in delta fashion.

  • Patent number: 10901648
    Abstract: A cloud storage system includes a processor and a non-transitory computer-readable medium to store blob table management instructions for execution by the processor. The blob table management instructions are configured to manage a plurality of storage requests for a blob stored in a storage stamp as snapshots in a blob table and selectively create a user snapshot of at least one of the snapshots in the blob table. When automatic snapshots are enabled, the blob table management instructions are configured to receive a first request to overwrite the blob. If the first request does not further specify a key of the one of the snapshots in the blob table, the blob table management instructions are configured to add a new snapshot to the blob table and maintain storage of a prior snapshot of the blob for a maximum period.
