    Abstract: An apparatus, comprising: a coupler adapted to couple to a drip chamber; a support member operatively coupled to the coupler; and an image sensor having a field of view and operatively coupled to the support member, wherein the image sensor is configured to view the drip chamber within the field of view; at least one processor operatively coupled to the image sensor to receive image data therefrom, wherein the at least one processor is configured to: capture a first image; create a first thresholded image from the first image by comparing each pixel of the first image to a threshold value; determine a set of pixels within the first thresholded image connected to a predetermined set of pixels within the first thresholded image; filter all remaining pixels of the first thresholded image that are not with the set of pixels, the filter operates on a pixel-by-pixel basis within the time domain to generate a first filtered image; remove pixels determined to not be part of a drop from the first thresholded image using the first filtered image to generate a second image; determine a second set of pixels within the second image connected to a predetermined set of pixels within the second image to generate a third image, the third image identifies the second set of pixels within the second image; determine a first length of the drop by counting the number of rows containing pixels corresponding to the second set of pixels within the third image, the first length corresponding to a first estimated drop size; update a background image using the first image; create a second thresholded image by comparing first image with background image; sum the rows of second thresholded to create a plurality of row sums, each row sum corresponds to a row of the second thresholded image; start at a row position of the second thresholded image having a first sum of the plurality of sums that corresponds to the first length; increment the row position until the row position corresponds to a corresponding row sum that is zero; determine a second length is equal to the present row position, the second length corresponding to a second estimated drop size; and average the first and second lengths to determine a average length, the average length corresponding to a third estimated drop size.

    Abstract: The application relates to an endoscope with pannable camera. An endoscope has a pannable camera at the distal end of its insertion shaft, the pannable camera assembly being pivotable to provide a range of a field of view that can be equal to or greater than 180 degrees. A terminal light emitting element may be mounted to the camera assembly in order to illuminate the immediate field of view of the camera sensor regardless of the rotational position of the camera assembly. A fluid-carrying conduit of the insertion section may also be used to house functional components, including the camera assembly, actuation cables, a communications cable connected to the camera sensor, and/or a fiberoptic cable providing light to the light emitting element. A distal section of the endoscope handle may be rotatable relative to a proximal hand-held section of the endoscope handle, a rotary encoder being provided to convert the rotational position of the insertion shaft relative to the handle into a signal for the purpose of image orientation correction by an electronic processor.

    Abstract: sistema e método para estimativa de espaço livre. a presente invenção refere-se a um sistema e método para estimar o espaço livre e designar probabilidades de espaço livre nos dados de nuvem de pontos associados a um veículo autônomo que percorre uma superfície, incluindo levar em consideração o ruído do sensor, a disponibilidade do sensor, a alturas de obstáculos, e a distância dos obstáculos a partir do sensor. o sistema e método podem incluir determinar planos de superfície e classificar os pontos da nuvem de pontos de acordo com o fato de se, ou não, os pontos se encontram nos planos de superfície, entre outros fatores.
