Abstract:
A WIM (weigh-in-motion) sensor has an oblong hollow profile and includes two force-transmission plates arranged parallel to each other. A tube is arranged between the plates and is integrally formed with the plates and defines a hollow space. Two supports that are arranged opposite one another are formed inside the hollow space, each support extending away from a respective plate and between which a measuring element is received centrally in the tube under preload. The tube includes two tube segments designed to be mirror-symmetrical with respect to each other, which join the plates together and on the inside adjoin the hollow space. The wall thickness of each tube segment has a relatively thick region between at least two relatively thin regions.

The present disclosure also describes methods for measuring the tension in the guide wire as well as installing a device for measuring the tension in the guide wire.
Abstract:
The present invention provides improved load-indicating devices for use with structural assemblies that require accurate tensioning of fastening components such as nuts and bolts. In one embodiment, the load-indicating device comprises a body portion defining a bore extending therethrough, a movable member disposed in at least part of the body portion and configured to move in a direction substantially orthogonal to the axis of the bore, and an adjustment means coupled to the movable member and operable to displace the movable member when the body portion is compressed.
Abstract:
A bumper assembly of a mobile robot includes a sliding member which is installed to be movable in front and rear directions with respect to a robot body, a first elastic member which is coupled to the sliding member and presses the sliding member in the front direction, a first sensor which senses a movement of the sliding member when the sliding member moves in the rear direction, a front plate which is disposed at a front side of the sliding member, rotatably coupled to the sliding member, and moves integrally with the sliding member when the sliding member moves in the front and rear directions, and a second sensor which senses a rotation of the front plate when the front plate rotates.
Abstract:
The object of the invention is to provide a bed with a load detection function. The invention provides a bed with a load detection function that detects a load applied to a bed body, using a load detector attached to the bed body, and detects the state of a user on a bed surface of the bed body. Additionally, a load detector suitable for the bed is provided.
Abstract:
A personal items network, comprising a plurality of items, each item having a wireless communications port for coupling in network with every other item, each item having a processor for determining if any other item in the network is no longer linked to the item, each item having an indicator for informing a user that an item has left the network, wherein a user may locate lost items. A method for locating lost personal items, comprising: linking at least two personal items together on a network; and depositing one or both of time and location information in an unlost item when one of the items is lost out of network.
Abstract:
A load detector and an electronic unit using load detectors include a load sensor having a projective pressure receiving part, a case in which the load sensor is placed with the pressure receiving part facing toward the upper surface of the case, and an elastic body placed on the same side as the upper surface of the load sensor, the elastic body configured to receive a load and press the load sensor in its height direction.
Abstract:
A floor test apparatus is provided, including a base having an upper surface and defining an output shaft opening, a frame disposed in the base, having a main vertically projecting channel in communication with a supplemental, generally horizontally projecting channel having an access opening in a sidewall of the base. A main drive shaft passes through the supplemental channel and being coupled to a gearbox disposed in the main channel. A secondary shaft projects generally from the gearbox and is connected for common rotation with the main drive shaft.
Abstract:
A device for measuring deformations of a rotor blade of a wind turbine generator system includes an angle measuring device and an arm. The angle measuring device includes a first and a second assembly. The first assembly is pivotable relative to the second assembly about an axis. The second assembly has a fastening site that is configured to be connected to the rotor blade. The angle measuring device is configured to measure a relative angular position between the first and the second assembly. The arm has a connection site disposed at a distance to the fastening site and is configured to be connected to the rotor blade at the connection site. The arm is mechanically coupled to the first assembly at a radial distance such that, in response to a change in the distance, a relative angular displacement is generated between the first and the second assembly.
Abstract:
A tactile sensor includes a flexible medium having electrically conductive strips embedded therein and extending in a first direction, said electrically conductive strips including conductive nanostructures dispersed in a flexible support material, said nanostructures selected from conductive nanowires, carbon nanotubes, and graphene, wherein each electrically conductive strip is connected at each end to an impedance measuring device that measures the impedance across each electrically conductive strip. The electrically conductive strips may be formed on a first layer of the flexible medium by using direct-write technology.
