Abstract: Systems, apparatus and methods are provided for measuring moving vehicle information. Moving vehicle information may be measured by a sensor configured to respond to one or more wheels of the vehicle, where one or more of the wheels changes the characteristic impedance of the sensor at the wheel's contact location. An electrical time domain reflectometry signal processing system which is capable of measuring the change in the impedance of the sensor and converting the impedance change to a signal may be connected operatively to the sensor. A data-processing system receives the signal and extracts the vehicle information therefrom.

Abstract: A method of constructing a sensor includes depositing a first material in a predetermined arrangement to form a structure. The depositing results in at least one void occurring within the structure. The method further includes depositing a second material within the voids. The second material may have electrical properties that vary according to deformation of the second material. The method also includes providing electrical access to the second material to enable observation of the one or more electrical properties. A sensor includes a structure that has one or more voids distributed within the structure. The sensor also includes a material deposited within the one or more voids. The material may be characterized by one or more electrical properties such as piezoresistivity. The sensor includes a first contact electrically coupled to a first location on the material, and a second contact electrically coupled to a second location on the material.

Abstract: Strain sensing may be provided. First, a strain threshold for a circuit board may be determined. Then a strain capacitor may be selected that will fail when the circuit board is subjected to the strain threshold while the strain capacitor is mounted on the circuit board. The strain capacitor may be ceramic and may be in a commercially available size. The strain capacitor may then be mounted to the circuit board and monitored for failure.

Abstract: An overload detecting assembly comprising a lateral probe (18) which cooperates with a first load bearing member (10) as it moves towards a second load bearing member (11) and in turn deflects an indicator member (20) which may take a permanent set when a yield point is exceeded. Ready inspection of the indicator member reveals whether or not it has been bent. The indicator member may comprise a cantilevered beam (24) formed in a sleeve (20) coaxial with the load bearing members (10, 11). Alternatively, an extension (25) of the probe (18) may deflect laterally at a midpoint under overload conditions. Alternatively, the probe (18) may form an impression in an indicator member (30) under overload conditions.

Abstract: The present invention is to provide an imperceptible motion sensing device, which includes a non-conductive elastomer made of a pliable and elastic non-conductor (e.g., polyurethane) and having a bumpy side formed with at least one sunken portion thereon, at least one conductive fiber positioned in the at least one sunken portion respectively (e.g., by sewing), and a conductive elastomer made of a pliable and elastic conductor (e.g., a conductive foam or conductive rubber) and provided on the bumpy side of the non-conductive elastomer. When the sensing device is compressed by an external force, corresponding portions of the conductive elastomer and the non-conductive elastomer are compressed and deformed, causing contact and hence electrical connection between the conductive elastomer and the at least one conductive fiber. Thus, the imperceptible motion sensing device not only provides more accurate and more sensitive signal detection, but also ensures consistent performance even after long-term use.
