A system to monitor a composite system component may include a plurality of sensors mounted proximate to the composite system component. A signal processing unit may receive, from each of the plurality of sensors, a series of sensed values associated with the composite system component and determine a kurtosis value for each series of sensed values. A threshold exceedance detector may detect if at least one of the kurtosis values exceeds a pre-determined threshold value. A delamination location estimation unit may calculate an estimated location of a composite system component delamination alert signal based on calculated time difference delay values of detected signal impulses in the series of sensed values using at least four of the plurality of sensors. A delamination alert output may then transmit a composite system component delamination alert signal, along with the estimated location, when at least one of the kurtosis values exceeds the pre-determined threshold.

A method and apparatus are disclosed for monitoring a linear position, such as the distance between a sensing element and a movable object, and/or related parameters, such as displacement, direction, speed, velocity, and/or acceleration. The method utilizes a sensing element and an electrically conductive portion of the movable object, or a conductive target coupled to the movable object. The apparatus includes at least one sensing element formed by a section of a coupled slow-wave structure. The sensing element is connected to an RF or microwave generator, and an electronic circuit that converts at least one electromagnetic parameter of the section of the coupled slow-wave structure into a position reading. Electric and magnetic fields excited in the sensing element are split so that most of the electric energy is concentrated inside of the sensing element, while most of the magnetic energy is concentrated outside of the sensing element. The distance that defines the linear position is measured as a resonant frequency, impedance, phase shift or other electromagnetic parameter.

A collision sensor assembly is attachable to a stationary structure such as a pallet rack, a door frame, the corner of a wall, or the like. The collision sensor is configured to sense when a collision occurs with the stationary structure such as when a piece of movable machinery contacts the stationary structure. The collision sensor assembly includes a sensor operatively connected to a processor which determines when a collision occurs, and produces a signal to an output signal generator to provide an external indication of the collision.

摘要:
A hammer movement detection device for detecting the movement of a hammer which strikes strings provided for each key of a keyboard musical instrument. The hammer movement detection device radiates light onto a hammer shank which moves with the hammer and detects at least the displacement of the hammer shank based on the light reflected from the hammmer shank. The movement detection device may be attached to a shank rail which supports the hammer shank in a freely rotatable manner. The hammer movement detection device may be supported using a fixed member which is supported above the hammer shank and below the pin board which is connected to the frame which supports the strings which are struck by the hammer.
