Abstract:
In a method for determining the radial modulus of elasticity of paper or a corresponding web-like material that can be reeled or wound on a reel, the connection between the force and deflection of a material arranged in layers is measured. The measurements of force and deflection necessary for calculating the radial modulus of elasticity are performed on a reel of paper or corresponding material outside the reeling or winding position by loading the reel with a press member.
Abstract:
The present invention involves a vehicle for passengers having a passenger safety system. The system has a crash sensor, a vehicle seat with a weight sensor assembly, an air bag and an air bag controller. The crash sensor is capable of providing a signal when the vehicle experiences an impact force of a predetermined magnitude. The vehicle seat is capable of supporting a vehicle occupant, with a seat frame member attached to a vehicle floor pan. The seat frame member has a rigid end and a resiliently flexible end, the resiliently flexible end able to resiliently deflect with respect to the vehicle floor pan upon experiencing a force due to the weight of the vehicle occupant. The sensor assembly has a cantilevered beam, a fulcrum, and a sensing device. The cantilevered beam has only one point of fixed attachment for connecting to the vehicle floor pan and the seat frame member, and is capable of resiliently deflecting upon experiencing a load force and capable of returning to its pre-load orientation after said load force is removed. The fulcrum is located beneath the free end of the cantilevered beam so as to prevent the beam from permanently deforming under extreme loading conditions. The sensing device is located beneath the cantilevered beam and is adapted to provide a signal when said beam is subjected to a load force of a predetermined magnitude. The airbag is suited to rapidly deploy and provide protection to the passengers when the vehicle experiences an impact force of a predetermined magnitude. The airbag controller is capable of interpreting signals from the crash sensor and sensing device to determine whether to deploy the airbag when the vehicle experiences an impact force of a predetermined magnitude.
Abstract:
A torque applying tool includes a handle and a function end which includes two jaws. A first resistive strain gauge and a second resistive strain gauge are respectively connected to two respective insides of the two jaws. A third resistive strain gauge is connected to the handle and electronically connected to the first and second resistive strain gauges. A display unit is connected to the handle and electronically connected to the third resistive strain gauge. The display unit displays the value of torque that is a result of calculation of information from the resistive strain gauges.
Abstract:
The invention provides increased structural monitoring systems that have sensitive continuous coaxial cable sensors. A preferred embodiment sensor cable of the invention includes an inner conductor, a dielectric jacket, and an outer conductor that is configured to passively deform responsively to strain in an associated structure. The deformation can be aided by the physical structure of the dielectric jacket, the outer conductor, or a combination of both. The deformation translates strain into a measurable change in a reflection coefficient associated with the outer conductor.
Abstract:
The invention relates to a precision load cell with an elastic body comprising a base end, a load or force receiving part and two or more beams connecting said base end and said load or force receiving part. At least one of the beams constitutes a lever connecting the load or force receiving part and a flexible wall of a sensor cavity placed in the base end. The flexible wall is adapted for undergoing deformation as the result of a displacement of the load or force receiving part through an action of the lever, and the sensor means are adapted for measuring the deformation of the flexible wall or the strain in the flexible wall.

A detection sensor includes a detector unit which is provided on an insulating board at a first side of the board, a circuit component which is provided on the board at a second side of the board and which processes a signal detected by the detector unit, and a wiring unit which penetrates through the board in the thickness direction of the board and connects the detector unit and the circuit component.
Abstract:
A coupled spring system is applied to dynamic force spectroscopy measurements. A microcantilever-mounted probe acts as a first spring, and a supported micromachined membrane acts as a second spring. The coupled spring system provides a system spring constant that is lower than either spring individually. By probing different regions of the membrane, the spring constant of the system can be varied.
