    摘要: A system (10) and method for supplying uninterruptible power has active power negotiation and an extended range. The system includes a housing (12), a power supply input (14), a power source equipment input (16), a powered device output (18), an alternative power supply (20), and a control module (22). The control module (22) includes a comparator (36), a switch (38), a converter (40) and an injector (34). The injector includes a regulator (45) and power autonegotiation module (47). The injector actively manages the power to the powered device, even when the PoE available from older power source equipment differs from the PoE requirements of an updated powered device. There can also be an Ethernet switch (49) as a power source equipment extension between the powered device and the system. The Ethernet switch extends the range of the powered device from the system.

    摘要: The tool re-positions a floor guide supporting a climbing screen. The climbing screen includes a mounting arm that extends along a longitudinal axis and is fixed to a floor of a construction. The tool includes a first member fixable to the floor of the construction at a first position along the axial length of the mounting arm, a second member fixable to the mounting arm at a second position spaced along the longitudinal axis of the mounting arm from the first member, and a driver linking the first and second members to one another and operable for varying the spacing between the first and second members along the longitudinal axis.
