  • Patent number: 10229451
    Abstract: A method for processing transaction information for a commodity object is provided. The method includes receiving a request for purchasing a commodity object and generating, based on the request, a transaction order. The transaction order may include transaction amount information, information about a first user selling the commodity object, and information about a second user purchasing the commodity object. The method may further include setting an amount of fund in a fund account of the second user to a frozen state, and after a preset time period, transferring the amount of fund to a fund account of the first user. After the amount of fund is set to the frozen state and before the amount of fund is transferred to the fund account of the first user, an income produced by the amount of fund may be calculated and transferred to the fund account of the second user.

  • Patent number: 10222981
    Abstract: Embodiments that relate to displaying holographic keyboard and hand images in a holographic environment are provided. In one embodiment depth information of an actual position of a user's hand is received from a capture device. The user's hand is spaced by an initial actual distance from the capture device, and a holographic keyboard image is displayed spatially separated by a virtual distance from a holographic hand image. The user's hand is determined to move to an updated actual distance from the capture device. In response, the holographic keyboard image is maintained spatially separated by substantially the virtual distance from the holographic hand image.

  • Patent number: 10216446
    Abstract: A solution to deduplication in a storage system is disclosed herein. In this solution, a controller stores, at a first storage address, a data block that is written for the first time, and inserts, in a fingerprint table, a first fingerprint of first data that is written for the first time, but does not establish a mapping relationship between the first fingerprint and the first storage address. When receiving subsequently written second data to be written, the controller allocates a second storage address to the duplicate second data, stores the second data at the second storage address, and establishes a mapping relationship between the first fingerprint and the second storage address in the fingerprint table. This reduces an amount of data in the fingerprint table.

  • Patent number: 10218435
    Abstract: A downhole tool apparatus is disclosed that includes an input fiber optic cable coupled to an electro-optic modulator. The input fiber optic cable propagates first and second actively orthogonally polarized light beams. The electro-optic modulator modulates the first and second actively orthogonally polarized light beams in response to a measurement data stream (e.g., telemetry data). A single light beam comprising the modulated first and second actively orthogonally polarized light beams is propagated over an output fiber optic cable so that the modulated first and the second actively orthogonally polarized light beams propagate the same data through the output fiber optic cable. Recovery circuitry coupled to the single light beam is then used to detect, demodulate, and decode the original measurement data stream.
