  • Publication number: 20190147076
    Abstract: A system may generate a score for a predictive model based on receiving a streaming data flow of events associated with a predictive model for a tenant. The system may receive the streaming data flow and calculate one or more feature values in real time based on the reception. The system may store each of the calculated features to a multi-tenant database server. The system may calculate a score for the predictive model based on the storage and may transmit an indication of the score (e.g., a prediction) based on the calculation. The system may transmit the score to, for example, a computing device.

  • Patent number: 10287244
    Abstract: The present invention provides a process for purifying methionine. A methionine product having a purity of up to 99% or higher is obtained by separating methionine from a salt by-product through a process comprising adsorption and desorption using a macroporous adsorption resin, where the methionine content in the salt by-product is ?0.03%. The yield of methionine extracted with the resin is up to 98% or higher. By using the process of the present invention, the existing production process is simplified, the quality of the methionine product is improved, and the production costs for methionine are reduced.

  • Publication number: 20180308365
    Abstract: Systems and methods for automated vehicle guidance based on coded lighting to enable automated vehicle following and/or regrouping. Systems use projectors to project temporal identifiers for space partitioned by pixel projections. Different space partition is associated with a different identifier. By using simple light sensors mounted on the vehicles, and decoding the sensed light signal, the vehicle can determine its precise location in the space relative to the coded light projector. This information may be used for precise vehicle guidance to enable vehicle following and/or regrouping. For vehicle following, the coded light projector is placed on a moving vehicle. For vehicle regrouping, the coded light projector may be placed on a ground or on a pole. Depending on the guidance precision requirements, the coded light precision may be adjusted by using light projectors with different resolutions.

  • Patent number: 9904283
    Abstract: Precision docking is one of the most important tasks for drones and surface robots to charge themselves and load/unload packages. Without accurate docking, surface robots and drones will miss their charging pad or charging contacts and cannot automatically charge themselves for later tasks. Described is a system using coded light to guide the precision docking process for drones and ground robots. More specifically, the system uses projectors to project temporal identifiers for space partitioned by pixel projections. Different space partition gets a different identifier. By using a simple light sensor on a drone or a ground robot, the drone or the ground robot can know its precise location in the space and therefore knows where to move for a precise docking. Depending on docking precision requirement, the coded light precision may be adjusted by using projectors with different resolutions.

  • Patent number: 9849693
    Abstract: Computerized systems and computer-implemented methods that enable printing on a large solid surface, such as a floor, wall, or ceiling using mobile printer heads guided by coded light. In one implementation, a user points a projector onto the printing surface to project a sequence of images with a unique temporal identifier (ID) for each pixel, wherein different space partitions are associated with different pixel IDs. The mechanical transmissions of the conventional printers are replaced with the aforesaid coded light used in conjunction with small mobile printer heads equipped with light sensors, while the coded light is used to guide the printer heads' movements during the printing process.

  • Publication number: 20170345403
    Abstract: Finger-tracking systems and methods for virtual instruments playback. The described system tracks the position of user's ten fingers on a projection surface and can be used to play virtual instruments such as virtual piano, drums, and bells. The system tracks the movement of user's ten fingers while keeping them free of encumbrance or excessive postural constraints. More specifically, in one or more embodiments, a coded light based projector is used to send out location signal onto a flat surface, and ten light sensors are mounted on user's fingers to receive these signals and locate user's fingers. Based on their locations and relative distance to a fixed point, a printed music instrument can be used for virtual instrument music playback. With the described tracking system, various embodiments of virtual music instruments may be implemented, including a system and method for virtual piano playing as well as virtual Chinese bell playing on printed keyboard and printed Chinese bell set.

  • Patent number: 9717059
    Abstract: Embodiments of the present invention disclose a power control method and apparatus, relate to the field of wireless communications, and are invented for reducing power pressure of an air interface of a base station and ensuring a stable network environment. The method includes: determining whether received total wideband power (RTWP) of an air interface exceeds a set first congestion threshold value; when the RTWP of the air interface exceeds the set first congestion threshold value, sending a congestion indication to a radio network controller (RNC), where the congestion indication is used for indicating that the RNC is forbidden from up-regulating a target signal-to-interference ratio (SIR); receiving a target SIR sent by the RNC; down-regulating the target SIR sent by the RNC; and notifying, based on the down-regulated target SIR, a user equipment (UE) to reduce transmit power. The present invention is mainly applied to the field of power control.
