  • Publication number: 20260124093
    Abstract: Described are a gait rehabilitation robot and gait rehabilitation robot and training method thereof, the gait rehabilitation robot including: a pair of footplates; a pair of footplate supports; a pair of gait actuators; a controller; and a memory, wherein the controller receives at least one of a state value and a control command value relating to the corresponding motor from each gait actuator under a load condition, and calculates anteroposterior forces exerted on each of the footplates by the corresponding foot during the gait training based, for each gait actuator, on a difference between at least one of the received state value and control command value and the corresponding reference value stored in the memory for a present gait trajectory and speed. Thus, a gait status can be determined based on the difference between the anteroposterior forces exerted on each footplate under no-load and load conditions.

  • Patent number: 12000935
    Abstract: An integrated GNSS signal having a plurality of signal components with arbitrary power allocation may be processed. In an embodiment, an integrated signal processing unit of a GNSS receiver may generate in parallel complex rotated samples for a sample of the integrated signal. The complex rotated samples (e.g., early and late complex rotated samples) may be accumulated in parallel in a window that spans any arbitrary width that is less than or equal to a number of code chips in a PRN code sequence. In an embodiment, the integrated signal processing unit may sequentially generate complex rotated samples for the sample. The complex rotated samples (e.g., early, punctual, and late complex rotated samples) may be sequentially accumulated in the window. The GNSS receiver may utilize the accumulated complex rotated samples to perform correlation techniques, perform multipath mitigation techniques, and/or track the integrated signal.

  • Patent number: 11225859
    Abstract: Methods and systems produce petroleum products by insulating a thermal hydrocarbon recovery process from heat loss to surrounding areas of a formation utilizing an insulating composition including a non-gaseous phase component introduced into the reservoir that is different from water and insoluble in the hydrocarbons. The insulating composition may be disposed in the reservoir adjacent to where the heat loss is desired to be limited. In addition, the insulating composition may be disposed in a thief zone and may also be from an agent activated to form the composition at such desired locations by selecting activation dependent on at least one of temperature, time delay and oil saturation.

  • Patent number: 10920545
    Abstract: A particularly effective well configuration that can be used for single well steam assisted gravity drainage (SW-SAGD) wherein steam flashing through production slots is prevented by including passive inflow control devices (ICDs) or active interval control valves in the completion. A thermal packer separates the injection and production segments of a horizontal well having a toe and a heel, and the ICDs can be evenly spaced or can decrease towards the heel. The cumulative steam to oil ratio (CSOR) of the SW-SAGD well is thus lowered, as compared to the same well without passive flow control devices or active interval control valves.
