The hunter's hood with an adjustable face opening has fabric side panels and a fabric center panel that are sewn together. A face opening is encircled by a fabric tube that is sewn to the side panels and to the center panel by stitches. The fabric tube permits the passage of a persons head through the face opening. An elastic line passes through the right side panel, into the fabric tube, under the face opening, and out through the left fabric tube and side wall. An elastic upper line is mounted in the fabric tube above the face opening. An elastic line right end passes through a right loop end on the upper line. An elastic line left end passes through a left loop on the upper line. Tensioning the elastic line tensions the elastic upper line. Releasing tension on the elastic line releases tension on the upper line.

The invention relates to a disconnection method and device for obtaining the exact off-line length of a conductor of an overhead transmission line. The disconnection method comprises the following steps: firstly eliminating plastic creep deformation of the conductor; and secondly when the conductor is spread horizontally, applying a tension force as same as an equivalent on-line tension force to the conductor in the axial direction of the conductor, measuring the length of the conductor under the tension force, marking or cutting off the conductor at a position on which the length of the conductor is the same as the on-line length, and obtaining the conductor, the completion sag of which is matched with a designed sag requirement, after the conductor is singly suspended under the specific working condition. According to the disconnection method and device disclosed by the invention, before the length of the conductor is measured and obtained, the permanent extension of the conductor caused by the plastic creep deformation is reduced to maximum; the completion sag of the obtained conductor after being mounted meets the designed sag requirement, the completion sag is relatively stable in the certain period during the operation of a later line, and the safety and the reliability of the line operation are improved.

The invention discloses a method for monitoring anchor position and anchor line status of a floating-crane anchor winch, which is implemented on the basis of an anchor position and anchor line status monitoring device for floating-crane anchor winches. In the monitoring method, the tension of the anchor line is monitored in real time by using an anchor-line tension sensor, the length of the anchor line is monitored in real time by using an anchor winch barrel position sensor, and the anchor position is monitored in real time by using a GPS (Global Position System) orientator and a depthometer. The method can be used for accurately monitoring the anchor position and the anchor line status of the floating-crane anchor winch in real time. The method can ensure that the whole monitoring process is stable and accurate, thereby ensuring the operation quality and the operation safety of the floating crane.

The invention is a fishing pole with an integrated line tension measuring device Measured line tension is displayed in quantitative units, pounds or kilograms. A line tension warning system activates when the sensed line tension exceeds a threshold set by the fisherman. The line tension measuring device does not touch the fishing line so the fishing pole with integrated line tension measuring device fishes and operates like a normal fishing pole. The line tension measuring device may be integrated into the fishing reel seat which, in turn, is an integral part of the fishing pole.
