Abstract: A wound therapy system includes a dressing an instillation pump fluidly communicable with the dressing and configured to provide instillation fluid to the dressing, a negative pressure pump fluidly communicable with the dressing and configured to remove air from the dressing, and a control circuit communicably coupled to the instillation pump and the negative pressure pump. The control circuit is configured to control the instillation pump to provide an amount of the instillation fluid to the dressing, provide a soak period, and control the negative pressure pump to provide a cyclic variation of negative pressure at the dressing.

Abstract: A wound debridement system includes a wound dressing having an active layer and a wound interface layer. The active layer is formed from one or more transmission layers that are arranged about a central post. Activation of the transmission layers is configured to cause the movement of the wound interface layer relative to a tissue site to which the wound dressing is applied. A drive unit is operably attached to the central post. The drive unit is configured to generate and transfer a vibrational energy and/or a rotational movement to the transmission layer(s) via the central post. The resultant vibration and/or rotation of the transmission layer(s) is imparted onto the wound interface layer, thereby effectuating the desired movement of the wound interface layer relative to the tissue site, which allows for the debridement of debris that may be located at the tissue site.

Abstract: Blended operator and autonomous control in an autonomous vehicle, including: receiving sensor data from a plurality of sensors of an autonomous vehicle; determining, based on the sensor data, a degree of autonomous control for each control input of a plurality of control inputs; and applying the degree of autonomous control for each control input of the plurality of control inputs.

Abstract: A computer includes a processor and a memory storing instructions executable by the processor to instruct a first sensor to run at a scanning rate; in response to a trigger event, reduce the scanning rate; in response to receiving data from the first sensor indicating a newly present object, turn on a second sensor; and then record data from the second sensor. The second sensor has a higher power draw than the first sensor.

Abstract: The techniques disclosed herein identify ransomware attacks as they are occurring, improving the security and functionality of computer systems. Ransomware attacks are identified using a new probabilistic machine learning model that better handles the unique properties of ransomware data. Ransomware data includes a list of computing operations, some of which are labeled as being associated with ransomware attacks. In contrast to deterministic machine learning techniques that learn weights, probabilistic machine learning techniques learn the parameters of a distribution function. In some configurations, a radial Spike and Slab distribution function is used within a Bayesian neural network framework to better handle sparse, missing, and imbalanced data. Once trained, the machine learning model may be provided with real-time operations, e.g., from a cloud service security module, from which to infer whether a ransomware attack is taking place.

Abstract: An improved apparatus and method provide conditioning to a powder deposited on a substrate (e.g., a web), for example, by wetting the powder in a 3D printing apparatus. To achieve this in an exemplary implementation, a wetting apparatus is located between a powder dispenser and at least one top calendering roller in a direction of movement of the substrate, wherein the wetting apparatus is configured to apply a wetting agent to the powder on the substrate before the powder passes through the calendering roller. The wetting agent is comprised of a material which increases cohesiveness of the powder to prevent the powder from adhering to the top roller. In a particular implementation, the wetting agent is steam confined to an area of the substrate where the powder passes through the wetting apparatus, without wetting other areas of the substrate which are not in the wetting apparatus.

Abstract: An improved apparatus and method are provided to remove powder from a web, for example, in a 3D printing apparatus. A flexible blade is provided to contact and move across a first portion of the web located between adjacent portions of the web to scrape powder from the first portion without removing powder deposited on the adjacent portions. A pair of edge vacuum nozzles and a central vacuum nozzle are also provided to move with the flexible blade to remove powder from both edges of the first portion and a central region of the first portion.

Abstract: Improved carrier plates and methods of use thereof are provided to secure and transport individual layers of a multilayer structure during manufacture of the multilayer structure. In one implementation a carrier plate is provided including a lower portion and a raised portion to support a flexible substrate holding an individual layer laid on an upper surface of the raised portion. Clamping mechanisms, such as rollers, are formed on extended regions adjacent to side walls of the raised portion. The clamping mechanisms are configured to move from open positions, where the clamping mechanisms are spaced apart from the sidewalls of the raised portion, to closed positions, where the clamping mechanisms secure opposite edge portions of the flexible substrate between the clamping mechanisms and the first and sidewalls of the raised portion.

Abstract: A headlight assembly for assembly adjacent at least one skin component of a vehicle includes a housing supporting at least one light and a lens attached to the housing. The lens includes at least one attribute for engaging the at least one skin component. The attribute may be a pin or an aperture formed in the lens which may extend a distance from a surface of the lens for guiding the skin component. The skin component may be a grille and the attribute may restrict movement of the headlight assembly relative the grille in a Y-axis direction forming a margin therebetween. The attribute may be a channel including a bracket for guiding the skin component, for instance, a facia into the channel. The attribute may be a cavity formed in the lens for receiving an overlapping portion of the skin component, for example, a grille.
