    摘要: An impact sensor includes a piezoelectric transducer operatively connected to a chromic device. The chromic device includes a chromic material that changes from a first color state to a second color state in response to electric power generated by the piezoelectric transducer when exposed to a given level of impact force. The chromic material is bistable so that the chromic material remains in the second color state for a significant amount of time. An impact force to which the sensor has been subjected may be quantified by observing the chromic device. In one embodiment, the chromic material is an electrochromic material, such as a viologen, that changes through a color gradient of light transmission states from the first color state to the second color state. A printed color gradient may be used to aid in quantifying the impact force. In another embodiment, the chromic device includes a thermochromic material.

    摘要: Ali apparatus for supporting at least one electrical connector body, the apparatus includes a mechanical frame assembly mountable to a printed circuit board (PCB) and separable from the at least one connector body and the PCB. The frame assembly includes at least one base member for attachment to the PCB; and a plurality of rigid body members each spaced apart from one another and extending from the at least one base member or an adjacent rigid body member. The plurality of rigid body members receive a grouping of one or more connector bodies and a pair of adjacent rigid body members are configured to receive and support at least a portion of an entire length of respective opposing side surfaces defining each connector body. When a lateral force is applied to the connector body, the frame assembly acts as a support and transfers the lateral force to the PCB, thereby reducing a rotational moment at a base of each connector body connected to the PCB.

    摘要: An apparatus and method allow accurately determining properties of an anisotropic material, such as a multilayer printed wiring board, in a non-destructive manner using scanning acoustic microscopy. The apparatus and method includes special signal processing that allows determining the time of flight of an input waveform from a transmitter transducer on one side of the printed wiring board to a receiver transducer positioned on the opposite side of the printed wiring board in a position that opposes the transmitter transducer. The special signal processing includes an auto-correlation function and a cepstrum analysis. Once the time of flight is determined, the velocity of the input waveform may be computed. The Young's modulus and shear modulus for the printed wiring board may then be computed from the velocity of the input waveform. The preferred embodiments allow determining properties of a printed wiring board without the necessity of destructive testing.
