Abstract: A take-off apparatus and method for unmanned aerial vehicle without landing gear includes an unmanned aerial vehicle, a carrier, a lock/release mechanism, a lift or airspeed sensing module, a signal processing module and a release motion sensing module. The lock/release mechanism locks the unmanned aerial vehicle onto the carrier and controllably releases the unmanned aerial vehicle from the carrier. The lift or airspeed sensing module senses an overall lift or airspeed of the unmanned aerial vehicle. When the lift or speed value of the unmanned aerial vehicle is greater than a predetermined threshold, it drives the lock/release mechanism into an unlocked state so that the unmanned aerial vehicle is released from the carrier and takes off more accurately and successfully.

Abstract: A monitoring system for monitoring the condition of and energy guide chain and/or a cable guided in an energy guide chain. Energy guide chains are used for guiding cables, hoses or the like, between abase and a moving end displaceable along a travel path and, in so doing, form a mobile run connected to the moving end, a stationary run with a connection end for the base and a deflection arc between the two runs. A monitoring device with at least one sensing component arranged on the energy guide chain. The monitoring device evaluates a signal generated using the sensing component in order to monitor the occurrence of a fault condition during operation of the energy guide chain. The sensing component includes an electrical indicator conductor guided by the energy guide chain and extending along the greater part of the length of the mobile run. To monitor the condition of a cable and in this case includes two electrical indicator conductors guided by the energy guide chain, the one end of which is connected to the monitoring device and the other end of which is short-circuited.

Abstract: An over-pressure indicator, including a cup-shaped body having, on its bottom, a hole inside which is sealably housed a mobile element loaded by a spring towards the bottom of the cup-shaped body, the mobile element facing an indicator sensitive part for communication with an area where pressure verification is wanted. The mobile element coupled with a signaller of a movement thereof. The spring pressed by a pre-loading ring nut screwed onto the cup-shaped body. The nut torsionally removably coupled with a calibration cap of the indicator. The calibration cap having at least one stop that, when it abuts against a portion of the cup-shaped body, limits further screwing of the nut thus determining pressure beyond which mobile element movement is allowed. The movement causing intervention of the indicator so by coupling the suitable calibration cap and indicator and screwing it in fully, setting the indicator intervention pressure is possible.

Abstract: A measuring element for registering forces comprises a first measuring arm extending in a longitudinal direction of the measuring element, a second measuring arm extending in the longitudinal direction, a deformation section connecting the first measuring arm and the second measuring arm to one another in an elastically deformable manner, and a transformer unit arranged on a first side or a second side of the deformation section. The first measuring arm and the second measuring arm can be deflected relative to one another in a direction perpendicular to the longitudinal direction. The transformer unit responds to deformation and is situated fully within the deformation section.

Abstract: Provided is an analysis apparatus configured to analyze characteristics of a viscoelastic material based on a viscoelastic material constitutive law in which an elastic element and a viscoelastic element are arranged in parallel with each other; calculate, in a viscoelastic material model divided into a finite number of elements each having a node, a displacement amount of the node; calculate a strain rate at the node through use of the displacement amount; calculate, as a relaxation time of the viscoelastic element, a value proportional to a value of a power using the strain rate as a base and a value of a power using a shift factor of a temperature-time conversion law as a base; and calculate a stress at the node through use of the relaxation time.

Abstract: A load-sensing device is arranged in a package forming a chamber. The package has a deformable substrate configured, in use, to be deformed by an external force. A sensor unit is positioned in direct contact with the deformable substrate and is configured to detect deformations of the deformable substrate. An elastic element within of the chamber is arranged to act between the package and the sensor unit to generate, on the sensor unit, a force keeping the sensor unit in contact with the deformable substrate. The deformable substrate may be a base of the package, and the elastic element may be a metal lamina arranged between the lid of the package and the sensor unit. The sensor unit may be a semiconductor die integrating piezoresistors.

Abstract: A sensor for electrically measuring a force distributed unevenly across a measurement surface of the sensor includes a spring device between a measurement surface and a counter-surface. A first measuring element is arranged in or on the measurement surface and a second measuring element is arranged in or on the counter-surface, the elements substantially completely covering these surfaces in each case. The measuring elements include capacitor plates, and are designed such that the measuring signal can be generated from a distance between the measuring elements. The spring device has a large number of elastically designed spring members which are arranged spaced apart from each other by gaps so that each spring member upon loading by the force can deform into the gaps. This arrangement makes it is possible to measure unevenly distributed forces between bodies which may be of very different forms.

Abstract: Described is a force sensor stack configured to measure incident force. Data from the force sensor stack may be used to determine a weight of an object, determine a force distribution of the object resting on the force sensor stack, and so forth. The force sensor stack may comprise a plurality of force sensor layers. Each of the force sensor layers may be responsive to a different range of applied forces. The combined force sensor stacks may thus provide a wide dynamic range. A pressure concentrator layer may be configured to direct the incident force to particular portions of the force sensor layers.

Abstract: A directional force sensor and sensing system are described. The directional force sensor includes a leaf spring and one or more load sensors disposed about the leaf spring such that in response to a force applied to the leaf spring, the one or more load sensors provide a signal. A controller is coupled to receive signals from the one or more directional force sensors and determines characteristics of forces applied to the directional force sensors.
