Crimp tool is for and a method forms a strain relief connector including an optical fiber, a cover enclosing the optical fiber. The cover has an inner surface, an outer surface, a first end and a second end, the first end having a tapered portion that extends radially outwardly. A sleeve surrounds the cover and has a first inner volume and a first interior shoulder, a portion of the outer surface of the tapered portion abuts the first interior shoulder. The sleeve and the cover are simultaneously compressed forming a compressed portion. The cover and the sleeve are deformed such that the cover substantially fills the first inner volume of the sleeve.

It takes great effort by players of a bowed string musical instrument to manipulate proper bow-to-string pressure that directly affects the quality of the sound generated. This invention is a training device that provides bow-to-string pressure reading as feedback to players. The device consists of a rib cage, a base unit, and a liquid crystal display unit. The rib cage emulates strings and transfers bow pressure to the base unit. The main components of the base unit include a pressure sensor and microcontroller circuit board. The liquid crystal display unit displays reading sent by the microcontroller board.

Methods and systems are provided for calibrating a compressor surge line. In one example, a method may include adjusting the compressor surge line based on a vehicle speed in addition to a compressor pressure ratio. For example, at higher vehicle speeds, above a threshold vehicle speed, a less aggressive surge line calibration may be utilized in order to improve drivability while at lower vehicle speeds, below the threshold vehicle speed, a more aggressive surge line calibration may be utilized for NVH mitigation.

A rotating cylinder device includes a cylindrical belt having an axis line, several plate-shaped parts, several link mechanisms, and a cylindrical casing. The plate-shaped parts are disposed outside the belt and arranged symmetrically across the axis line. The link mechanisms are pivotally connected to the respective plate-shaped parts and one end of each is pivotally connected to one plate-shaped part and the other end has a moving protrusion. The moving protrusions are adapted to move along a first direction parallel to the axis line. The cylindrical casing is adapted to rotate about the axis line and is coupled to the moving protrusions. When the cylindrical casing rotates about the axis line, the moving protrusions are driven to move along the first direction, and the plate-shaped parts are driven by the link mechanisms to move along a second direction perpendicular to the axis line, to contract the belt.
