Abstract: Venous infusion catheter assemblies and methods of use are described herein. A catheter assembly may comprise an elongated body having a proximal end and a distal end, with an expandable occlusion element disposed on the elongated catheter body. A catheter may include a first infusion lumen extending to a proximal infusion port positioned on the catheter body proximally of the occlusion element and a second infusion lumen extending to a distal infusion port. Some embodiments may use a suction lumen extending to at least one suction port. When the catheter is introduced into vasculature of a patient, the suction port may be positioned in the patient's superior vena cava or right atrium to draw blood, the distal infusion port is positioned to direct normothermic or hyperthermic fluid toward the patient's heart, and the proximal infusion port is positioned to create a flow of hypothermic fluid in the patient's cerebral vasculature.

Abstract: Co-located sensors in a sorting facility are disclosed, including: a first sensor associated with a first field of view, and wherein the first sensor is located in a sorting facility; a second sensor associated with a second field of view, wherein the second field of view is adjacent to or overlaps with the first field of view, and wherein the second sensor is located in the sorting facility; and one or more processors configured to: receive a first image including a first set of objects from the first sensor; receive a second image including a second set of objects from the second sensor; and evaluate the first image and the second image to determine a sorting decision with respect to a target object.

Abstract: Centralized control of multiple sorting facilities is disclosed, including: a feedback interface configured to collect sorting results feedback data from a first sorting facility, wherein the first sorting facility is associated with a second sorting facility; and one or more processors configured to reconfigure a set of sorting facility devices located in the second sorting facility based at least in part on the sorting results feedback data.

Abstract: Time-varying control of a controllable air stream is disclosed, including: a set of image sensors configured to capture image data showing a target object being conveyed by a conveyor device along a Y-direction; an array of air jets located along an X-direction, wherein the X-direction crosses the Y-direction; and a processor configured to: receive the image data from the set of image sensors; determine a classification of the target object within the image data; and modify a two-dimensional firing polygon of air to be directed by the array of air jets on the target object based at least in part on the classification of the target object; and wherein the array of air jets is configured to perform a sorting operation on the target object as the target object is translated across the array of air jets based at least in part on the modified two-dimensional firing polygon.

Abstract: Dynamic bale creation is disclosed, including: a plurality of sorting facility devices configured to capture objects from a material stream based at least in part on target sorting metrics specified by a bale recipe; and one or more processors configured to: determine current sorting metrics associated with captured objects that are to be added to a collection mechanism at a sorting facility; and determine whether to trigger reconfiguration of at least a subset of the plurality of sorting facility devices based at least in part on a comparison between the target sorting metrics and the current sorting metrics.

Abstract: A system that provides a guide arm, a ratchet arm frame configured to be coupled to the guide arm, a ratchet arm configured to be coupled to the ratchet arm frame, and a sagittal sizing guide body configured to be coupled to the ratchet arm. The sagittal sizing guide body includes a first radiopaque object disposed at a first position and a second radiopaque object disposed at a second position that is spaced apart from the first position. The first radiopaque object has a length that corresponds to a length of a second prosthesis component. When the surgical alignment system is positioned for use on a patient, the first radiopaque object identifies a location at which a first resection of a first bone is to be performed.

Abstract: Systems and methods for assaying a test entity for a property, without measuring the property, are provided. Exemplary test entities include proteins, protein mixtures, and protein fragments. Measurements of first features in a respective subset of an N-dimensional space and of second features in a respective subset of an M-dimensional space, is obtained as training data for each reference in a plurality of reference entities. One or more of the second features is a metric for the target property. A subset of first features, or combinations thereof, is identified using feature selection. A model is trained on the subset of first features using the training data. Measurement values for the subset of first features for the test entity are applied to thereby obtaining a model value that is compared to model values obtained using measured values of the subset of first features from reference entities exhibiting the property.
