Abstract: The invention consists(including and not limited to) of the three interrelate and independent themes; I, the “AI Toilet” systems to changing Human stool excretions. Making its become a pleasures, to reducing anal diseases by more than 80%, Hemorrhoids will disappear from humanity. Used intelligent robots, smart sensors community, ect. II, Family data center. To protect the privacys, its changing internet ecology, made decentralization, Establishment every center of the each user family(web3.0+). It own triple protections; A, passware and three security questions, No transfor and saves into the home storage. B, disconnected communication between double barkups. C, Blockchain AI. III, all personal with home devices to IoT. any time any where access, View, Deal. Above nutual most advanced AI GPU, AI CPU, FPGA AI edgd computing, AI local database, AI remotely database, big data analytics, AI algorithms, Customized AI-IC designs.

Abstract: A removable arc welding torch head having a variable electrode receiving aperture that includes a number of discrete, slidable wedges guided within a conical interior surface to enable the head to be used with electrodes of various diameters without changing components of the torch head. The removable nature of the torch, while providing for adequate flow of inert gas, provides an adjusting collar that engages the wedges and forms an adjustable opening for an electrode to be inserted therein.

Abstract: An arc welding torch having a variable electrode receiving aperture including a number of discrete wedges guided within a conical interior surface of a housing to enable the use of electrodes of various diameters without changing components of the torch. An adjusting collar engages the wedges and forms an adjustable opening for an electrode to be inserted therein. Rotation of a tailpiece of the torch handle adjusts the position of the wedges and secures the electrode in position.

Abstract: A damping apparatus having a cylinder, a fluid, and a floating piston. The cylinder includes a fluid chamber with the fluid located within the fluid chamber. The floating piston is coupled to the cylinder to carry the fluid in the fluid chamber. The floating piston is movable in response to movement of the fluid when a force is applied to the cylinder.

Abstract: A bicycle fork having a damping apparatus that includes a cylinder, a damping fluid and a piston. The cylinder defines a chamber. The damping fluid is located in the chamber. The piston is disposed in the chamber and is positioned adjacent the fluid.

Abstract: A damping apparatus for use in a bicycle fork includes two telescoping legs, a rebound piston and a compression piston. A damping fluid is provided in the apparatus. The pistons and legs define compression rebound and variable zones into which the fluid may flow to provide desired damping.

Abstract: The present invention is directed to stadium seating and stadiums incorporating the seating. The invention includes a unitary seat component having a platform seat portion and a back portion formed integrally with one another. The invention also includes a side support which is configured with a arcuate flange receiving channel enabling the seat component of the invention to be installed to the side component. In this fashion, spaced apart side components are useful for attaching a plurality of seats such that a seat is positioned between a pair of side supports and a side support positioned between adjacent seats is shared as a common armrest for each adjacent seat. A channel and track structure is provided to anchor the sides to the stadium or platform floor in the desired fashion.
