The Vieussens valve, also known as the valve of the coronary sinus, is a structure located at the opening of the coronary sinus into the right atrium of the heart. It is a thin fold of tissue that acts as a valve, although it is not a true valve like the mitral or tricuspid valves in that it does not completely occlude flow.

Self-replicating machines in fiction refer to autonomous machines or robots that have the capability to reproduce themselves without human intervention. These machines often serve as a narrative device to explore themes such as the consequences of technology, evolution, and the nature of intelligence. In science fiction, self-replicating machines can take on various forms, from simple drones to complex systems capable of building entire cities or ecosystems.

White Family Rotary is a family of rotary engines manufactured by the White Motor Company, which was an American manufacturer of automobiles and trucks. The White family of rotary engines includes several variations and configurations, designed for different applications and performance requirements. These engines are notable for their innovative design and engineering features, often emphasizing smooth operation and high power-to-weight ratios.

A zigzag stitch is a type of sewing stitch that creates a zigzag pattern rather than a straight line. It is produced by moving the needle side to side while it stitches, which results in a series of diagonal lines resembling a zigzag shape. Zigzag stitches are commonly used in sewing for various purposes, including: 1. **Finishing Edges**: The stitch is effective for preventing fabric edges from fraying, making it popular for hems and seams.

A relieving tackle, also known as a "relieving tackle block" or "relieving tackle system," is a mechanical configuration of pulleys and ropes or cables used to lift, lower, or move heavy loads with greater ease and efficiency. This type of tackle is often employed in rigging and lifting operations, where it can be beneficial to distribute the weight of a load and reduce the amount of force required to move it.

A belt sander is a power tool used for sanding and smoothing surfaces, primarily wood. It employs a continuous loop of sandpaper, called a sanding belt, that is driven by a motor. The belt rotates around two or more rollers, providing a consistent and efficient sanding action. **Key features of a belt sander include:** 1. **Power Source**: Most belt sanders are electric, although battery-operated versions are also available.

"Jointer" can refer to different things depending on the context: 1. **Woodworking Tool**: In woodworking, a jointer is a tool used to create a flat surface on a piece of wood. It typically has a long flat bed, and wood is passed over the blades to remove material and ensure flatness. It's primarily used for flattening and jointing the edges of board to prepare them for gluing or other types of joinery.

A table saw is a powerful woodworking tool designed for cutting various materials, most commonly wood and sheet goods. It consists of a circular saw blade mounted on an arbor, which is driven by a motor. The blade extends through a flat, usually rectangular table, allowing the user to guide the material being cut across the surface.

The Boeing 2707 was a proposed supersonic transport (SST) aircraft developed by Boeing in the 1960s. Its design aimed to compete with the Concorde and the Soviet Tupolev Tu-144, both of which were operational supersonic airliners. The 2707 program was notable for its ambitious goals, including a large passenger capacity and advanced aerodynamic features.

"Daktylios" typically refers to the concept in ancient Greek culture associated with the Dactyls, who were mythical beings often linked to the mountains of Phrygia. In Greek mythology, the Dactyls were frequently associated with healing and the discovery of metals and were sometimes viewed as the inventors of certain arts, including music and gymnastics.

A High-Occupancy Vehicle (HOV) lane is a designated lane on a highway or road reserved for vehicles with multiple passengers, typically encouraging carpooling and the use of public transportation. The main goal of HOV lanes is to reduce traffic congestion, improve air quality, and promote the efficient use of road space.

OVMS stands for Open Vehicle Monitoring System. It is an open-source platform designed for monitoring and managing electric vehicles. OVMS allows users to track various vehicle parameters remotely, such as state of charge, location, and performance, using a mobile app or web interface. The system is generally installed in electric vehicles and can provide functionalities such as: 1. **Real-time monitoring**: Users can see the vehicle's current status, including battery level and location.

"Routes" can refer to different concepts depending on the context. Here are a few common interpretations: 1. **Geographical Routes**: These refer to paths or directions between two points, typically used in navigation or transportation. For example, driving routes, walking paths, bike trails, etc. 2. **Internet Routing**: In computer networking and the internet, a route is a path that data takes from its source to its destination.
