    Abstract: A system that includes a driving component, such as a motor, and a driven component. The system also includes a torque limiter positioned between the driving component and the driven component. The driving component is coupled to a driving end of the torque limiter and the driven component is coupled to a driven end of the torque limiter. The torque limiter is configured to assume a normal operating state with no slippage between the driving and driven ends of the torque limiter and an over-torque operating state with slippage occurring between the driving and driven ends of the torque limiter. The torque limiter includes a metal moving part that assumes a first position when the torque limiter is in the normal operating state and a second position different than the first position when the torque limiter assumes the over-torque operating state. An inductive proximity sensor monitors the position of the metal moving part.

    Abstract: A linear actuator especially for adjustable furniture comprises a spindle (16) with a spindle nut (16a) for bringing about the adjustment of the article of furniture. At the end of the spindle (16) there is a bearing (17) for mounting of this in the actuator. The spindle/spindle nut (16,16a) is driven by an electric motor (27) through a transmission (28). For preventing accidents and/or damage during the adjustment of the article of furniture the actuator is equipped with a squeeze protection based on a piezo element (22). This piezo element (22) is arranged in connection with the bearing (17) for registering the forces or deflections of the forces affecting the spindle (16). In that the piezo element (22) has a through-going hole for the spindle the mounting of the piezo element (22) is simplified and further it has turned out that a particularly good signal/noise ratio is obtained.

    Abstract: A load indicator comprises a load bearing assembly of first and second load bearing members (23, 22) connected together to bear a lateral load applied to the first member (23), the first load bearing member defining a cavity (25) with the second load bearing member such that it is frangible above an indicator load, and the cavity (25) containing an indicator liquid which escapes from the cavity once the first load bearing member is fractured by said load. The load bearing members (22, 23) comprise cylindrical members arranged concentrically with the outer member (23) having a portion of reduced thickness to render it frangible and to define the cavity (25). The cavity (25) includes an internal volume within the second load bearing member (22). The load indicator may be configured as a load bearing pin to connect two components.

    Abstract: Systems and methods for passively determining when a threshold force has been exceeded. An example apparatus includes a housing and a substrate that is attached at one end to an interior portion of the housing. The substrate includes at least one conductive trace, each having two ends. The substrate is configured to fail when the threshold force has been experienced. The metal trace ends are electrically accessible from an exterior side of the housing. Prior to delivery, the housing is connected to a package that includes one or more force sensitive devices. Upon arrival of the package, the at least one conductive trace is electrically tested to determined if the substrate has failed. If the substrate has failed the package has experienced a force greater than the threshold force.

    Abstract: A clamping element for the transport of a substrate in a predefined transport direction comprises a first and a second leg with a first and second clamping jaw for clamping a substrate. Each of the two clamping jaws has a clamping plate which is movable in transport direction relative to the corresponding leg. A sensor measures the deflection of the first clamping plate relative to the first leg. As soon as the measured deflection exceeds a predefined threshold value, the clamping element is opened.
