Abstract: A computer system displays a first object that includes at least a first portion of the first object and a second portion of the first object and detects a first gaze input that meets first criteria, wherein the first criteria require that the first gaze input is directed to the first portion of the first object in order for the first criteria to be met. In response, the computer system displays a first control element that corresponds to a first operation associated with the first object, wherein the first control element was not displayed prior to detecting that the first gaze input met the first criteria, and detects a first user input directed to the first control element. In response to detecting the first user input directed to the first control element, the computer system performs the first operation with respect to the first object.

Abstract: A kit is disclosed for use in replacing damaged hose segments of high pressure hydraulic hoses having press-fitted, straight or curved reusable end couplings. The disclosed kit includes at least one pair of support blocks; at least one mandrel having an outside diameter corresponding to the inside diameter of each hose segment to be replaced; at least one removal plate having a centrally disposed aperture corresponding to the outside diameter of each hose segment to be replaced, an elongated slot providing access to the aperture from one side of the plate, and a recess defining an annular shoulder around that portion of the aperture not communicating with the elongated slot; an adjustable pressure plate for use with hose assemblies having curved end couplings; and a U-shaped pusher bar for use with the adjustable pressure plate.
