Power tools with conductive couplings used with active injury mitigation technology are disclosed. Conductive couplings are particularly relevant to table saws, hand-held circular saws, track saws, miter saws, and band saws with active injury mitigation technology. Conductive couplings provide a mechanism through which an electrical signal can be coupled or imparted to a blade, and then monitored for changes indicative of human contact with the blade. An exemplary conductive coupling includes a brush that establishes an electrical connection with a moving part of a power tool, and the brush maintains contact with the moving part of the power tool during at least 40 hours of cumulative time when the motor is spinning the arbor and blade without an interruption in the electrical connection sufficient to trigger the reaction system. A conductive coupling may be two-sided compliant. A conductive coupling may connect to a motor shaft to minimize electrical noise.

A web material converting line is disclosed, in particular for converting tissue paper, including a plurality of converting sections arranged in sequence along a feeding direction of a web material to be converted, each section including a converting machine; at least one converting section of the converting line includes a detection system for detecting the presence of people near the converting section. The detection system includes at least a first presence sensor and is adapted to detect the presence of people in at least a controlled area. The controlled area is subdivided into an accessible area 5 that can be accessed when the line is working, and an alarm area. The detection system is adapted to distinguish between the presence of an individual in the accessible area and the presence of an individual in the alarm area. The detection system is connected to a control unit adapted to intervene on the operation of the converting section based on information provided by the detection system.

The present invention relates to a safety protection device, disclosing an anti-squeezing device for mobile console, comprising: an opening/closing mechanism pivotally mounted in the area of an operating desktop of the mobile console, capable of pivotally opening from a closed state in a direction away from the operator in response to the squeezing thrust of the operator to form a dodging space; and a position signal detection mechanism mounted to detect and transmit an opening/closing position signal of the opening/closing mechanism, so that a control unit of the mobile console may perform control operations based on the opening/closing position signal. The present invention further discloses an application-specific pusher-type anti-squeezing device for mobile console and an aerial work machine. The anti-squeezing device provided by the present invention can provide an effective dodging space while performing anti-squeezing operation, and has the advantages of wide protection angle range, high safety and high stability.

An automation unit for handling component carriers has an enclosure for arranging components carriers within a first, a second and a third stacking space. The enclosure has a loading opening for the first stacking space, a transfer device for transferring component carriers between the stacking spaces, and a separating device to selectively separate or release the first stacking space inwardly. A safety system for an intervention area is at the loading opening to interrupt the operation of the automation unit if it detects an intervention. The safety system may switch to partial monitoring mode, to full monitoring mode after completion of an automated loading process or deactivate in a manual loading mode when the separating device separates the first stacking space. The safety system may switch to full monitoring mode before the separating device releases the first stacking space. The automation unit can be loaded both automatically and manually safely.

A safety cutting tool includes an electrically conductive cutting member, an electric motor for actuating the cutting member, a gripping handle electrically insulated from the cutting tool, a cutting trigger control that can be actuated by the hand of the user gripping the gripping handle, the cutting trigger control being electrically insulated from the cutting tool, an emergency stop device sensitive to a user coming into contact with the cutting member. The emergency stop device is controlled by a comparator comparing an impedance of a first electric circuit comprising the cutting tool and a second electric circuit used as a reference, the first and second circuits having manual contact electrodes provided on at least one of the gripping handle of the tool and the cutting trigger control. A method for controlling such a tool is also disclosed. The tool and method are is-applicable to electric secateurs and shears.

A press cover anti-pinch device and an apparatus having a press cover is disclosed. The press cover anti-pinch device comprises: a connector arranged at a lower side of a cover body of the press cover and fixed to the press cover; and a support hinged to the connector and rotatably arranged in a supporting position or in a collapsed position, wherein when the support is arranged in the supporting position, the support swings down and supports the press cover on a supporting surface, and when the support is arranged in the collapsed position, the support is collapsed and the press cover is lowered. During use, when the press cover is in an opened state, the support swings down and supports the press cover on the supporting surface, so that the support provides a supporting force to the press cover.
