  • Patent number: 12649063
    Abstract: The present invention relates to a stimulation generator suitable for use in an implantable neurostimulator, including an injectable neurostimulator. The stimulation generator is adapted to provide a configurable stimulation signal comprising a component, such as a pulse. The stimulation generator comprises circuitry to receive and combine an amplitude control signal and a duty cycle signal to produce a preliminary output voltage signal which includes the component of the stimulation signal. It further comprises a voltage-controlled current source adapted to be driven by the preliminary output voltage signal; and a mode selector controlled by a stimulation mode signal to output the component from the preliminary output voltage signal as a current-controlled component of the stimulation signal via the voltage-controlled current source or as a voltage-controlled component of the stimulation signal.

  • Publication number: 20260087776
    Abstract: A selective multi-view method and a 3D object recognition subsystem for 3D object classification. The method includes inputting, by a 3D imaging sensor, a 3D data representation of a 3D object, extracting, by processing circuitry, multiple view images from the 3D data representation of the 3D object, selecting, by the processing circuitry, a most influential view based on an assignment of importance scores using a Cosine similarity method between visual features detected by at least one pre-trained convolutional neural network (CNN). The method further includes predicting, by the processing circuitry, a classification of the 3D object based on the selected most influential view and outputting, by the processing circuitry, a class of the 3D object. The subsystem may be implemented for a robotic pick and place manipulator.

  • Publication number: 20260038713
    Abstract: A method of manufacturing a corrosion-resistant wireline cable includes embedding a first layer of armor wires onto a core cable using a heated carbon fiber reinforced polymer. A second layer of carbon fiber reinforced polymer is then extruded to envelop the first layer of armor wires. In one method, a layer of virgin or colored polymer is extruded over the second layer, and a second layer of armor wires is embedded through the virgin or colored polymer, displacing it to envelop the outer armor wires. In another method, each wire in the second armor layer is coated with virgin polymer before being embedded into the second carbon fiber reinforced polymer layer. The assembly is then heated to cause the virgin polymer to migrate outward, forming an outermost layer. In both methods, a final jacket layer is applied over the exterior to complete the cable. The resulting cable provides corrosion resistance and mechanical reinforcement.

  • Patent number: 12450830
    Abstract: The present disclosure relates to a method for estimating physical properties of an object. The method includes generating a three-dimensional (3D) reconstruction of a real-world environment based on an input media. Further, the method includes estimating a current set of physical parameters of the object using a physics-based prediction model and a real-world visual content while the object is manipulated. Further, the method includes generating a simulation variant and computing a cost function based on comparing the simulation variant and the real-world visual content. Furthermore, the method includes estimating the physical properties of the object based on optimizing the current set of physical parameters with the cost function such that a similarity between the simulation variant and the real-world visual content increases.
