Abstract: A marine vessel propeller to convert engine rotational power into propulsive thrust is of a built-up propeller (BUP) type having a circular array of propeller blades, wherein each propeller blade is a single piece including a blade part and a base part. The base part has a generally circular inner surface with a number of radially extending cylindrical indents provided with planar end wall and fastening holes arranged through the base part at a location of the indents. A cylindrical insert is provided with a hole parallel to a longitudinal axis of the insert and arranged to fit into the indent, such that the propeller blades are attachable to a propeller shaft using exemplary fastening bolts through the fastening holes and inserts. A propeller blade and method for installing a marine vessel propeller are also disclosed.

Abstract: A method of joining first and second blade components of a rotor blade of a wind turbine includes providing corresponding first and second positioning elements at an interface of the first and second blade components. The method also includes aligning and securing the first positioning element of the first blade component with the second positioning element of the second blade component so as to temporarily secure the first and second blade components together. Further, the corresponding first and second positioning elements maintain a desired spacing between the first and second blade components. Moreover, the method includes permanently securing the first and second blade components together such that the desired spacing is maintained between the first and second blade components.

Abstract: Systems and methods are disclosed that provide smart alerts to users, e.g., alerts to users about diabetic states that are only provided when it makes sense to do so, e.g., when the system can predict or estimate that the user is not already cognitively aware of their current condition, e.g., particularly where the current condition is a diabetic state warranting attention. In this way, the alert or alarm is personalized and made particularly effective for that user. Such systems and methods still alert the user when action is necessary, e.g., a bolus or temporary basal rate change, or provide a response to a missed bolus or a need for correction, but do not alert when action is unnecessary, e.g., if the user is already estimated or predicted to be cognitively aware of the diabetic state warranting attention, or if corrective action was already taken.

Abstract: This document discloses techniques, apparatuses, and systems for sparse encodings for control signals. Integrated circuits (ICs) may transmit various signals to manage interactions between circuit components of the IC. These critical signals are common targets for malicious attacks because, when altered, they can cause the IC to perform differently than is intended, and in some cases, bypass security measures. To protect against these attacks, the sparse encodings for control signals described herein transmit critical signals with sparse encodings. Further, multiple rails may be used to transmit a single bit of the sparsely encoded critical signals across each rail. In this way, the techniques described herein may provide a scalable solution that may be adjusted differently based on each implementation.

Abstract: Techniques regarding measuring a position and transcriptome of one or more cells from a biological sample are provided. For example, one or more embodiments described herein can comprise a method, which can comprise covalently bonding a probe to a molecular structure located on a cell to label the cell according to a position of the cell with regards to a biological sample comprising the cell. The probe comprises an oligonucleotide sequence that can be indicative of the position.

Abstract: The present disclosure discusses a method of and an arrangement for the lubrication of a controllable pitch propeller of a marine vessel. The lubrication is based on continuous lubricant circulation from the hydraulic powerpack to the hub and back to the oil tank, when the marine vessel is sailing ahead with propeller blades locked in a desired position. The lubrication is performed by maintaining, at least when the propeller blades are locked in a desired position, a pressure difference between the astern oil chamber and the lubricant chamber for circulating lubricant from the astern oil chamber via the lubricant chamber to the oil tank.

Abstract: This disclosure is directed to the regulated injection of a chemical(s), solution(s) or material(s) hereafter referred to as chemicals into stormwater runoff, other surface waters or other fluid streams to promote the removal of a pollutant(s) or to alter the properties of the water. Specifically, and depending upon the types of chemicals injected, the physical, chemical and/or biological properties of the water can be altered. The invention provides a passive system to alter stormwater runoff or other surfaces. The system may be deployed at a remote site, such as a construction site, and implemented with minimal or zero external power requirements.
