Apparatus and methods for optimizing anchoring force are described herein. In securing tissue folds, over-compression of the tissue directly underlying the anchors is avoided by utilizing tissue anchors having expandable arms configured to minimize contact area between the anchor and tissue. When the anchor is in its expanded configuration, a load is applied to the anchor until it is optimally configured to accommodate a range of deflections while the anchor itself exerts a substantially constant force against the tissue. Various devices, e.g., stops, spring members, fuses, strain gauges, etc., can be used to indicate when the anchor has been deflected to a predetermined level within the optimal range. Moreover, other factors to affect the anchor characteristics include, e.g., varying the number of arms or struts of the anchor, positioning of the arms, configuration of the arms, the length of the collars, etc.

A tactile input apparatus comprising ring-shaped elements configured to conform to a user's fingers, tactile capacitance sensors operably affixed to periphery of the ring-shaped elements, and a control unit, is provided. Each tactile capacitance sensor is positioned parallel to the underside of each finger and reads a change in capacitance on contacting the user's thumb or palm. The control unit, in wired or wireless electronic communication with each tactile capacitance sensor and with the user's computing device, continuously transmits capacitance readings multiple times per second to a software on the computing device. The software monitors and processes the capacitance readings from the control unit and controls output to the computing device. The software determines logic and then enacts single or multiple custom outputs. The positioning of the tactile capacitance sensors on the periphery of the ring-shaped elements prevents confinement of the user's fingers and allows mobility of the user's fingers.

A drum tuning system which rotates clockwise or counterclockwise to adjust the tension of a drum head fitted over the open end of a drum body. It utilizes a rotating ring having numerous opposing equally spaced vertically projecting tabs along the top of the body's diameter, each with inward facing wheels that ride on the horizontal surface of a separate inner hoop bearing down on the drum head. The rotating actuator ring is fitted with multiple radial cleats projecting from its outside diameter for grasping it. A radius plate having horizontal holes extends from the drum body, and a tool engages the radial cleats on the rotating actuator ring to facilitate rotation. Multiple adjustable eccentric lugs are used to raise and lower the drum camming mechanism in relation to the open end of the drum body where attached. Horizontal projecting links support the drum attached to suspension mounting systems.

An apparatus for cutting and/or profile machining an edge of a pipe is provided. The apparatus includes a housing, a rotatable faceplate mounted on a front surface of the housing, and a tool holder mounted on the faceplate and holding a cutting tool. In a first embodiment, a cutting apparatus includes gearing that permits the tool holder to be moved relative to a surface of a pipe in a rapid-feed mode, a slow-feed mode and a rapid-return mode. In second and third embodiments, a profile machining apparatus includes a carriage having a profiling roller or shaft that advances (or retracts) relative to a pipe along a path defined by a template. The carriage to which the cutting tool is mounted is pivoted about a support shaft permitting the carriage and tool to change its angle and orientation relative to the pipe while advancing or retracting.

Disclosed is a highly efficient turbine nozzle blade that reduces the number of blades in an axial-flow turbine while reducing secondary-flow loss. In the nozzle blade, when a differential pressure between a pressure side and a suction side of each blade, at the same axial chord position of the blade, is defined as a load of the blade, and a ratio between axial chord length “Cx” of the blade and an axial distance “xp” from a leading edge of the blade at a maximum load position that maximizes the blade load is defined as a maximum load relative position, Cx is greater at a hub and tip than at an intermediate vertical portion, and simultaneously a maximum load relative position at the hub and tip is set to be nearer to a trailing edge thereof than a maximum load relative position of the intermediate vertical portion of the blade.

Disclosed is a medicine feeding apparatus. The medicine feeding apparatus includes a medicine cartridge, a cartridge mount, a medicine discharge mechanism, and a discharge drive mechanism. The medicine cartridge has an entrance opening formed in the top thereof, through which a medicine product is put into the medicine cartridge, and a discharge hole formed in a front position of the bottom thereof, through which the medicine product is discharged from the medicine cartridge by operation of the medicine discharge mechanism. The entrance opening is provided with a cover. The medicine cartridge is mounted on an upper surface of the cartridge mount, and the cartridge mount has an outer discharge hole communicating with the discharge hole to discharge the medicine product from the cartridge mount. The discharge drive mechanism is provided at the medicine cartridge and the cartridge mount and serves to drive the medicine discharge mechanism.

A solar collector with a rectangular frame (1), preferably made of extruded or rollformed metal, containing an absorber plate (3), an insulating layer (2) beneath the absorber plate (3), and a cover pane (4) spaced above the absorber (3). Absorber tubing (3b.3c) is attached to the rear side of the absorber plate.
