An apparatus includes a sensor assembly. The sensor assembly includes a transmission-line assembly having an electrical transmission-line parameter configured to change, at least in part, in response to reception, at least in part, of a vehicular load of a moving vehicle moving relative to a vehicular roadway to the transmission-line assembly positionable, at least in part, relative to the vehicular roadway.

Systems and methods of detecting, identifying, and classifying objects positioned on a shelf are provided. In one exemplary embodiment, a sensor pad comprises a plurality of electrical contacts disposed in the pad as a matrix of rows and columns of electrical contacts. Further, each contact corresponds to a different surface area of the pad and has a first electrical conductor positioned on a first layer and a second electrical conductor positioned opposite to the first conductor on a second layer. Also, at least one of the first and second conductors is operable to vary in resistance or capacitance based on an amount of pressure applied to that conductor. In addition, each contact is configured to enable an electrical connection between the first and second conductors with a resistance or capacitance that varies based on an amount of pressure applied to a corresponding area of the pad when an object is positioned on that pad.

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 moving vehicle, where one or more of the wheels change 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 moving vehicle information therefrom.

Techniques are disclosed for systems and methods to detect and/or classify a vehicle occupant, such as a passenger seated within the cockpit of a vehicle. An occupant classification system includes an occupant weight sensor, an occupant presence sensor, and a logic device configured to communicate with the occupant weight sensor and the occupant presence sensor. The logic device is configured to receive occupant weight sensor signals from the occupant weight sensor and occupant presence sensor signals from the occupant presence sensor, determine an estimated occupant weight and an occupant presence response based, at least in part, on the occupant weight sensor signals and the occupant presence sensor signals, and determine an occupant classification status corresponding to the passenger seat based, at least in part, on the estimated occupant weight and/or the occupant presence response.

A weighing device includes a weighing module, a processor, and an output device. The weighing module includes a suspension component, a deformation component, and a sensor. The deformation component includes an elastic piece, a connecting portion, and a fixing portion. The elastic piece is coupled between the connecting portion and the fixing portion. The suspension component includes a hook and a lanyard. One end of the lanyard is fixed to the connecting portion, and a second end of the lanyard is passed through the fixing portion and coupled to the hook. When the hook suspends an object to be weighed, the hook moves the connecting portion toward the fixing portion and deforms the elastic piece. The sensor detects a deformation amount of the elastic piece. The processor calculates a weight of the object according to the deformation amount and an elastic coefficient of the elastic piece.
