摘要： A system includes: a control unit; a pattern visualization device; and a sensor couplable to the control unit. The sensor is configured to sense a parameter of an environment surrounding at least two objects and to provide the sensed parameter to the control unit. The control unit is couplable to the at least two objects and to the pattern visualization device. The control unit is configured to control, based on the sensed parameter, a relative positioning of at least a first one of the at least two objects with respect to at least a second one of the at least two objects. The pattern visualization device comprises means for moving at least one of the objects based on the controlling of the relative positioning by the control unit.

摘要： We generally describe a winch (100) comprising: a plurality of ropes (130, 140) coupleable to a first load (200) or to different respective second loads (200, 210); a support frame (110); and a first roller (150) moveably coupled to the support frame (110), wherein a first rope (150) of the plurality of ropes (130, 140) is moveable over the first roller (150); wherein a movement of the first roller (150) is configured to shorten and/or lengthen a usable length of the first rope (140) of the plurality of ropes (130, 140), and wherein the shortening and/or lengthening of the usable length of the first rope (140) is configured to raise and/or lower the first load (200) or one of the second loads (200, 210) to which the first roller (150) is coupleable via the first rope (140).

摘要： A winch (100, 200) includes a rope (105), an overwinding sensor (106) coupled to the rope (105) where the overwinding sensor (106) is moveable between a first position and a second position upon winding and/or unwinding of the rope (105). The overwinding sensor (106) includes a first electrically conducting member, a contact member (104) having a second electrically conducting member which is contactable by the first electrically conducting member when the overwinding sensor (106) is in the second position. The second electrically conducting member is not contactable by the first electrically conducting member when the overwinding sensor (106) is in the first position. The winch (100, 200) is configured to stop and/or prevent and/or hamper winding of the rope (105) upon establishment of an electrical contact between the first electrically conducting member and the second electrically conducting member when the overwinding sensor (106) is in the second position.

摘要： A winch having a rope and a rigid member coupled, at a first end portion of the rope, to the rope. The rigid member is coupleable to a load raisable and/or lowerable by the winch, where the rigid member is configured to substantially increase an effective length of the load to stabilize the load when being raised and/or lowered by the winch.
