Abstract: Systems and methods for embodiments of a hyperdexterous robotic system using groundless user input devices (UIDs). In some embodiments, the hyperdexterous system allows for the slave control to follow the master control even when the two are misaligned. The motion of the master control occurring in multiple degrees of freedom may be decoupled into its component parts and processed differently. Each degree of freedom may be processed independently and scaled differently. For example, in some embodiments, only the roll motion of the groundless user interface device is transferred, in some embodiments, the master slave control is only allowed when the master and slave are within a certain region of each other.

Abstract: An example imaging apparatus comprises a light source, an imaging spectrometer, an image sensor, control circuitry, and processing circuitry. The light source generates power for delivery at a molecular sample, which can include at least 100 mW. The imaging spectrometer separates light emitted from the molecular sample into a plurality of different component wavelengths. The control circuitry causes the image sensor to scan one or more regions of the molecular sample while the imaging spectrometer is aligned with the image sensor and collects hyperspectral image data of the molecular sample from the light emitted that corresponds to the plurality of different component wavelengths. The processing circuitry performs an image processing pipeline by transforming the hyperspectral image data into data that is representative of a quantification of emitters, absorbers, and/or scatterers present in the one or more regions of the molecular sample.

Abstract: In general, techniques are described for processing a set of high-resolution images of an integrated circuit, the images captured at different locations with respect to the integrated circuit, to automatically align and “stitch” the set of high-resolution images into a larger composite image. For example, an imaging system as described herein may use sampled feature points distributed across different grid tiles within overlap regions for pairs of images to match feature points to inform the alignments of a pair with respect to each image in the pair. The system may in some cases further apply a bundle adjustment to iteratively align and refine the alignment results for each image in a set of images being processed. In some examples, the bundle adjustment is a best-fit adjustment based on minimizing the net error associated with the alignment of the set of images.
