Abstract: There is provided a method of lifting a shovel comprising an undercarriage and a superstructure with a counterweight. The method comprises configuring the shovel and a front lifting assembly and a rear lifting assembly on a lifting site in a lifting configuration wherein the front lifting assembly matches corresponding force applying points on a front portion of an undersurface of the superstructure and the rear lifting assembly matches corresponding force applying points on an undersurface of the counterweight, wherein at least one of the front and the rear lifting assemblies includes a lifting beam including a set of spaced-apart lifting units and an elongated beam extending inbetween; contacting the front lifting assembly and the rear lifting assembly with the corresponding force applying points on the undersurface of the front portion of the superstructure and the undersurface of the counterweight respectively; and starting a lifting operation to raise the superstructure to a desired height.

Abstract: In one embodiment, a flashlight virtual object is provided that has a field of view. Any portions of the representation that fall within the field of view of the flashlight virtual object are highlighted. The position and orientation of the flashlight virtual object is manipulated in three-dimensional (3-D) space using a pointing device that captures motion in two-dimensions, by translation of the flashlight virtual object about one or more of a plurality of user-selectable two-dimensional (2-D) planes, rotation of the flashlight virtual object about one or more of a plurality of user-selectable points, translation of the flashlight virtual object along, or parallel to, one or more of a plurality of user-selectable axis and/or automated movement to a nearest point.

Abstract: In one embodiment, a special paper plot (referred to herein as a dynamic plot) for which corresponding metadata is maintained is printed. A mobile appliance obtains corresponding metadata for the dynamic plot. A camera of the mobile appliance computes an image of the dynamic plot. A position of the camera of the mobile appliance with respect to the dynamic plot is calculated from the image of the dynamic plot. Using the calculated position, information or icons are overlaid at particular locations in the image captured by the camera of the dynamic plot. The image captured by the camera of the dynamic with the overlaid information or icons is then displayed on a display screen of the mobile appliance. A user may add annotations beyond what is printed on the dynamic plot. This information may subsequently be shared with other users involved in the project.

Abstract: The device (1) comprises means (3) which can detect a disturbance such as a discrete gust or a continuous turbulence, and means (4, A1 to An) for controlling the deflection of control surfaces (S1 to Sn) of the airplane, when such a disturbance is detected.

Abstract: Disclosed herein is a fish stringer for underwater maintenance of live captured fish, the fish stringer comprising, in combination: a buoyant element having a generally oblong shape and ballast in its underside, a towing line secured at one end thereof to the buoyant element and to be releasably secured at the opposite end to a watercraft, an angler or a fixed object, a fish stringing line secured at one end thereof to the buoyant element and having a needle element at the other end thereof for threading the fish stringing line through the gills and mouth of captured fish, the fish stringing line extending generally underwater below the buoyant element, and an adjustment structure for adjusting the operational length of the fish stringing line.
