    Abstract: An example method includes capturing a plurality of images of a rotating object using an imaging device optically coupled to a microscope. The method removing a first portion of a model of the rotating object based on a first contour of the rotating object in a first image of the plurality of images. The method includes orienting the model based on an amount of rotation of the rotating object between capture of the first image and capture of a second image of the plurality of images. The method also includes removing a second portion of the model of the rotating object based on a second contour of the rotating object in the second image.

    Abstract: A single point sensing system may include a microscope having a field of view, a single-point sensor having a focal point, a stage to support a substance, an actuator to move at least one of the single-point sensor and the stage relative to one another, and in alignment controller. The alignment controller is to identify a location of the substance on the stage based upon signals from the microscope and output sensor alignment signals to the actuator to align the location of the substance on the stage with the focal point of the single-point sensor based upon the identified location of the substance.

    Abstract: A three-dimensional volume modeling method may include rotating a three-dimensional biological object having a translucent outer surface to different angular positions, capturing different two-dimensional images of the three-dimensional biological object, each of the different two-dimensional images being at a different angular position, and modeling an exterior of the three-dimensional biological object based upon the different two-dimensional images. The method may further involve identifying a point of an internal structure of the three-dimensional biological object each of the two-dimensional images and modeling the internal structure of the three-dimensional biological object in three-dimensional space relative to the exterior of the three-dimensional biological object by triangulating the point amongst the different two-dimensional images using a three-dimensional volumetric template of the three-dimensional biological object.

    Abstract: A cellular object imaging system may include a growth platform. The growth platform may include a body having a cellular fluid suspension region, a media supply passage extending within the body to the cellular object fluid suspension region, at least one fluid pump on the body to selectively deliver media to the cellular object fluid suspension region, a waste discharge passage extending within the body from the cellular object fluid suspension region and a cellular object rotator on the body adjacent the cellular object fluid suspension region to rotate a cellular object within the cellular object fluid suspension region. The cellular object fluid suspension region permits optical imaging of the cellular object suspended in a fluid during rotation by the cellular object rotator.

    Abstract: In example implementations, an apparatus is provided. The apparatus includes a dielectrophoresis (DEP) separator, an electrical field generator, a tracking system, and a controller. The DEP separator is to separate a plurality of different particles. The electrical field generator is coupled to the DEP separator to apply a frequency to the DEP separator. The tracking system is to track a movement of a type of particles in the DEP separator. The controller is in communication with the electrical field generator to control the frequency and the tracking system to track the separation. The controller is to calculate a cross-over frequency from a cross-over frequency distribution for the type of particles based on a frequency sweep performed on the type of particles and the movement of the type of particles that is tracked.
