Mass calculating and indicating means for weighing moving vehicles
First Claim
1. A device for calculating the weight of a load, comprising,an impact sensor unit including a bladder adapted for travel of the load thereover, and a transducer operable for producing a signal by the flexure of the bladder caused by a load passing thereover, and in proportion to the extent of said flexure,a speed sensor operable for producing a signal, in response to sensing the speed of the load passing over the impact sensor unit, corresponding with the speed of the load so passing, andcomputer means operable for sensing said two signals and utilizing them and thereby producing a specific signal indicating the weight of the load.

Abstract
A mass calculation and indicating device particularly for weighing moving vehicles (trucks) on the highway. It includes means for sensing both the impact of the mass of the truck, and the speed, each producing an electronic signal, and using the signals to indicate the total weight of the truck. The mass is sensed by an impact component having a bladder, operating on fluid displacement, and producing an electronic signal thereby. The speed is sensed by a radar component, utilizing the Doppler effect, and produces another electronic signal. The two signals determine a signal which indicates the weight of the truck axles. The axles are sensed individually, both as to impact and speed, and the signals produced by these two factors are used as to each axle to show the weight of each axle, and are themselves combined to show the final total weight of the truck. A component is included to sense the presence of the truck in the sensing range, and its departure therefrom, to detect individual trucks following one another and thereby control the signals relating to each individual truck.
