Abstract: A surface cleaning apparatus including a body defining an agitation chamber, an agitator partially disposed within the agitation chamber and configured to rotate about a pivot axis, and a debrider at least partially disposed within the agitation chamber. The agitator includes an elongated body having a first and a second end, a sidewall extending radially outward from the elongated body extending between the first and the second ends, and a plurality of bristles extending radially outward from the elongated body. The plurality of bristles are arranged in at least one row adjacent to the sidewall. The debrider includes a plurality of teeth configured to contact a portion of the sidewall as the agitator rotates about the pivot axis.

Abstract: Systems and techniques that facilitate automated localization of large vessel occlusions are provided. In various embodiments, an input component can receive computed tomography angiogram (CTA) images of a patient's brain. In various embodiments, a localization component can determine, via a machine learning algorithm, a location of a large vessel occlusion (LVO) in the patient's brain based on the CTA images. In various instances, the location of the LVO can comprise a laterality and an occlusion site. In various aspects, the laterality can indicate a right side or a left side of the patient's brain, and the occlusion site can indicate an internal carotid artery (ICA), an M1 segment of a middle cerebral artery (MCA) or an M2 segment of an MCA. In various cases, a visualization component can generate and display to a user a three-dimensional maximum intensity projection (MIP) reconstruction of the patient's brain based on the CTA images to facilitate visual verification of the LVO by the user.

Abstract: One or more devices, systems, methods, and storage mediums using artificial intelligence application(s) using an apparatus or system that uses and/or controls one or more imaging modalities, such as, but not limited to, angiography, Optical Coherence Tomography (OCT), Multi-modality OCT, near-infrared fluorescence (NIRAF), OCT-NIRAF, etc. are provided herein.

Abstract: A modular valve system includes a number of functional components such as valves, pressure regulators, adaptors and manifolds for controlling a fluid flow through said valve system, and at least two connecting blocks of different configurations, each associated to one of said functional components. Each one of said connecting blocks constitutes a functional unit together with one functional component mounted on a functional side of said connecting block. All connecting blocks are formed in a rectangular block shape and have an inlet and an outlet on two opposing end sides constituting an inlet side and an outlet side, respectively. The inlet sides of all connecting blocks are of identical configuration. The outlet sides of all connecting blocks are also of identical configuration, wherein outlet and inlet of neighboring, coupled connecting blocks are aligned with each other. Therefore, functional units can be directly coupled for establishing a fluid flow.

Abstract: A micro-structured reference element for use in a sensor having a substrate and a dielectric membrane. The reference element has an electrical property which changes its value on the basis of temperature. The reference element is arranged with respect to the substrate so that the reference element is (i) electrically insulated from the substrate, and (ii) thermally coupled to the substrate. The reference element is arranged on the underside of the dielectric membrane. The reference element and side walls of the substrate define a circumferential cavern therebetween, which is also bounded by the dielectric membrane, arranged between them. The dielectric membrane is connected to the substrate. A surface area of the reference element which is covered by the dielectric membrane is greater than or equal to 10% and less than or equal to 100% of the possible coverable surface area.
