A tool system is provided that can include a tool body, a controller, and an actuator that is configured to implement a functionality. The tool system can include an extender in communication with the controller and a remote device in communication with the extender. The remote device can transmit a first signal to the extender. The extender can, in response to the first signal, transmit a second signal to the controller to cause the actuator to implement the functionality.

The invention is concerned with a method, arrangement, computer program and computer program product for estimating the thermal resistivity of soil surrounding an underground cable. The arrangement comprises a thermal resistivity estimating unit that obtains a first temperature (T.sub.s) from a first temperature sensor at an exterior surface of the cable, obtains a second temperature (T.sub.a) from a second temperature sensor placed in the soil at a distance from the cable, obtains a measurement of current (I.sub.c) transmitted in the cable and estimates the thermal resistivity of soil based on the first and the second temperatures (T.sub.s, T.sub.a) as well as on the current measurement (I.sub.c).

A repairing tool for an electric wire threading head for pressing and squeezing a drawing-in wire of the electric wire includes a first holding part, a second holding part opposite to the first holding part, and two positioning bolts for fastening the first holding part and the second holding part. A first half screw hole and a second half screw hole are protrudingly formed on the first holding part and the second holding part to form a complete screw hole. The drawing-in wire is pressed and squeezed through the positive rotation or reverse rotation of the repairing tool to form an external screw thread part and increase a screw thread area, and the surface of the external screw thread part is applied with instant dry adhesive and rotated into a pulling head, so that the drawing-in wire is closely adhered to the pulling head and tensile strength is improved.

An alignment tool for an electrical box having a plurality of screw holes includes a body portion and a plurality of limbs extending away from the body portion in a first direction. Each limb is insertable into a corresponding screw hole of the electrical box. An alignment member extends away from the body portion in a second direction opposite to the first direction and has an alignment target. Upon insertion of the limbs into the corresponding screw holes, the alignment target defines a midline of the electrical box.

A wire harness includes electrical wires and an outer covering member. The outer covering member includes tube portions different in cross-sectional shape and size and a guiding shape portion between adjacent tube portions. The guiding shape portion guides the electrical wires when inserted. A cap is provided to each one end of the electrical wires, and the electrical wires are passed through the guiding shape portion with the caps facing frontward. A wire harness and a method for inserting electric conductive paths through the wire harness can enhance workability related to the electrical conductive paths and an outer covering member while suiting the wire harness to the shapes and the usage environments.

A method and apparatus are disclosed for enabling an existing wire supplying DC current to an electrical load of a vehicle to serve as a clean line for transmission of a data signal without interference from electrical systems of the vehicle. The method comprises identifying opposite ends of the existing wire, cutting the wire at the opposite ends and inserting a respective inductor in series with the wire at each of the opposite ends, to define an intermediate wire section that extends between the two inductors, and coupling data transmitting and receiving units to the intermediate section of the wire to permit data transfer between the transmitting and receiving units.

A base is a platform that supports a component off the ground in a solar energy installation. The specific configuration of a base can vary based on the intended component, for example whether it holds a transformer or power component. Multiple bases are mechanically and/or electrically connected to form a system of bases in the field. Proper placement of bases and engagement of those bases is facilitated by mating alignment mechanisms such that one base can be lowered “fit” with another. A method of positioning components includes positioning a base and aligning and lowering a second base alongside the first such that the bases engage.

A clamping plier is disclosed, including a first and a second plier bodies. The first and the second plier bodies are connected together through a shaft, an elastic member is provided on the shaft. The first plier body includes a first handle and a first jaw and the second plier body includes a second handle and a second jaw. The first jaw is provided with a first clamping head and a first cable stripping head, and the second jaw is provided with a second clamping head and a second cable stripping head. The first crimping head and the second crimping head cooperate to form a terminal crimping position, the first and the second cable stripping heads cooperate to form a cable cutting and stripping position. The elastic member is connected between the first and the second crimping heads or between the first and the second cable stripping heads.
