  • Patent number: 11790487
    Abstract: A medical device that includes a sensor including a filter array. The sensor is configured to capture a raw image and the filter array is configured to filter the raw image into a frame of raw pixel values including first, second, and third pixel values. The medical device includes non-transitory computer readable medium storing demosaicing instructions that, when executed, causes a processor to exclude the first pixel values from the frame of raw pixel values. The processor generates estimated second pixel values at locations of the excluded first pixel values and the third pixel values on the frame, and generates estimated third pixel values at locations of the excluded first pixel values and the second pixel values on the frame. The processor creates a processed image having a partial-resolution frame from the second pixel values, estimated second pixel values, third pixel values, and estimated third pixel values.

  • Patent number: 11786109
    Abstract: Various apparatuses to attach a first medical device to a second medical device are described that allow the physician to grasp only a single device while the other device remains securely attached to the one being grasped. The apparatuses, once they are attached to the first medical device, are designed to be easily and quickly attached and detached to a second medical device, normally only requiring the use of one hand. Furthermore, the apparatuses oftentimes include a base that can easily couple and decouple from the portion that is attached to the second medical device so that if the need arises to separately use the second medical device, it can be decoupled from the first medical device without completely removing the apparatus from the second medical device.
