  • Patent number: 12632676
    Abstract: Described are systems and methods that guide an LLM in determining when to initiate a request to a user for clarification and when to cause execution of a determined directive based on an utterance. At each pass through the LLM it may be determined whether the probability score and/or confidence score of a determined token exceeds respective thresholds. Based on those determinations, the system may decide whether to proceed with the determined tokens or to request clarification.

  • Patent number: 12607595
    Abstract: Various embodiments of the present application are directed towards an ion-sensitive field-effect transistor for enhanced sensitivity. In some embodiments, a substrate comprises a pair of first source/drain regions and a pair of second source/drain regions. Further, a first gate electrode and a second gate electrode underlie the substrate. The first gate electrode is laterally between the first source/drain regions, and the second gate electrode is laterally between the second source/drain regions. An interconnect structure underlies the substrate and defines conductive paths electrically shorting the second source/drain regions and the second gate electrode together. A passivation layer is over the substrate and defines a first well and a second well. The first and second wells respectively overlie the first and second gate electrodes, and a sensing layer lines the substrate in the first and second wells. In some embodiments, sensing probes are in the first well, but not the second well.

  • Patent number: 12574633
    Abstract: Techniques for distributed camera synchronization are described herein. In an example, processing circuitry receives, from a processor, a first signal indicating a request to generate an image capture. The processing circuitry determines a first camera and a second camera. The processing circuitry determines a mapping of the first camera and the second camera to pins of the processing circuitry. A first pin of the pins is communicatively coupled with the first camera. A second pin of the pins is communicatively coupled with the second camera. The processing circuitry sends, using the first pin, a second signal to cause the first camera to generate a first image associated with the image capture. The processing circuitry sends, using the second pin, a third signal to cause the second camera to generate a second image associated with the image capture. The second image is captured synchronously with the first image.
