  • Patent number: 11875272
    Abstract: Compute engine circuitry configured to represent a spin network mapping of a graph representing a combinatorial optimization problem includes a plurality of ring oscillator cells, each of which includes a ring oscillator having an oscillator output, at least one coupling block, and a read block. Each coupling block connects the ring oscillator of the cell to the ring oscillator of one of a plurality of neighboring cells to form a coupled ring oscillator. The read block generates a state output for each coupled ring oscillator that indicates whether the coupled ring oscillator is in one of a same-phase state, in which the connected ring oscillators oscillate in phase with each other, and an opposite-phase state, in which the connected ring oscillators oscillate in an opposite phase from each other. A controller is configured to output a total energy of the mapping based on the state outputs.

  • Publication number: 20240011776
    Abstract: Localization and navigation systems and techniques are described. An electronic device comprises a processor configured to maintain a state vector storing estimates for a position of the electronic device at poses along a trajectory within an environment along with estimates for positions for one or more features within the environment. The processor computes, from the image data, one or more constraints based on features observed from multiple poses of the electronic device along the trajectory, and computes updated state estimates for the position of the electronic device in accordance with the motion data and the one or more computed constraints without computing updated state estimates for the features for which the one or more constraints were computed.

  • Patent number: 11866687
    Abstract: Techniques are described for automated microinjection of substances, such as genetic material, into single cells in tissue samples. An example system comprises a robotic manipulator apparatus configured to hold and position a micropipette. Furthermore, the system comprises a microscope camera positioned to observe an injection site. A computing device receives image data from a microscope camera of the system, where the image data represents an image of a tissue sample. The computing device receives, via a user interface, an indication of a line traced by a user on the image of a tissue sample. In response, the computing device controls the robotic manipulator apparatus to move a tip of the micropipette along a path defined by the trajectory line. The pressure controller injects a gas into the micropipette to eject a substance out of the micropipette at one or more points along the path defined by the trajectory line.
