  • AUTO-GENERATION OF PATH CONSTRAINTS FOR GRASP STABILITY
    Publication number: 20240198526
    Abstract: In some cases, grasp point algorithms can be implemented so as to compute grasp points on an object that enable a stable grasp. It is recognized herein, however, that in practice a robot in motion can drop the object or otherwise have grasp issues when the object is grasped at the computed stable grasp points. Path constraints that can differ based on a given object are generated while generating the trajectory for a robot, so as to ensure that a grasp remains stable throughout the motion of the robot.

  • SYSTEMS AND METHODS FOR RAPID FLUSHING OF A MEMBRANE-BASED SYSTEM
    Publication number: 20240198291
    Abstract: Systems and methods for rapid flushing of a membrane-based fluid filtration system are disclosed herein. During flushing, a membrane of the system can be decoupled from other portions of the system and brine can be flushed from the membrane separate from the other portions of the system. In some embodiments, the membrane can be connected to a pump to form a flushing loop that is separate from the flushing loops of the main system to flow the flushing fluid therethrough. The flushing fluid through the membrane can be optimized and set based on a flow rate of the membrane to prevent damaging the membrane while minimizing flush time of the membrane relative to the flush time of the system.

    Publication number: 20240199372
    Abstract: Disclosed are techniques for elevator control. In one aspect, a sensor senses time series data. A system module identifies a feature point of a target object in the time series data, determines whether feature point coordinates of the feature point are located in an offset space, wherein the offset space has a spatial offset to a button, and sends a control signal if the offset space does not overlap with a first sensing range and the system module determines that the feature point coordinates are located in the offset space for a duration exceeding a first threshold time, or if the offset space overlaps with the first sensing range and the system module determines that the feature point coordinates are located in the offset space for a duration exceeding a second threshold time. An elevator floor controller receives the control signal and cancels the triggering of the button.

  • GARDEN TOOL
    Publication number: 20240198786
    Abstract: This application belongs to the field of a garden tool and specifically relates to a garden tool including: a body; at least two traveling wheels located on two sides of the body; and a driving unit. The driving unit is installed inside the traveling wheel. In the present application, the driving unit is installed inside the rim.
