Patent number: 9599525Abstract: Pre-loaded force sensitive input devices, force sensing resistors (FSR), are formed as a multiple membrane assembly that is capable of detecting low intensity pressure inputs and quantifying varying applications of pressure to the sensor surface. Pre-loading the force sensor elements results in controlled amount of force between the two substrates causing a constant state of pre-load and eliminating the low-end or minimal pressure signal noise associated with unloaded sensors. Pre-loading the force sensing resistor sensors also enables the sensor to detect removal of low intensity pressure input such as might occur during theft of light weight articles placed in contact with the pre-loaded force sensor. Using an FSR or FSR Matrix Array will enable any handling of protected retail packaging to be detected and identified. A library of “touches” can be established that will yield cutting, ripping, twisting, etc. making the detection of a theft in progress more accurate.Type: GrantFiled: November 26, 2013Date of Patent: March 21, 2017Assignee: Sensitronics, LLCInventor: Franklin N.

Patent number: 8080742Abstract: The present invention provides an improved weigh-in-motion scale. A slight increase in the thickness of a an upper, flexibly-deformable metal plate in a thin, flexibly-deformable plate system coupled with a change in the transverse locations of the load cells provides the improved weigh-in-motion scale, which is capable of weighing substantially heavier loads than previously known weigh-in-motion scales. In use, as weight is applied to the weigh-in-motion scale, the upper flexibly-deformable metal plate elastically bends. The strain gauges thus provide a changing resistive value proportional to the bending of the flexible element and the weight applied, to generate signals to the Wheatstone bridge circuit, which then provides output signals from the Wheatstone bridge circuit, which are proportional to the force applied to the upper flexibly-deformable metal plate.Type: GrantFiled: February 27, 2009Date of Patent: December 20, 2011Assignee: International Road Dynamics, Inc.Inventors: Terrance Arthur Bergan, Randal Leroy Hanson

Patent number: 5753865Abstract: A method which determines the axle load of a vehicle consisting of measur the weight of a wheel while the vehicle is at a first angle of inclination, measuring the weight of the wheel while the vehicle is tilted at a second angle of inclination, and then calculating the axle weight from the two weight readings and the two angles. A front and rear wheel is selected in turn in order to determine both front and rear axle weights. Alternatively, there may be two different force measuring scales which detect two different force components of gravity exerted by the wheel due to the fact that the two different scales are set a different angle with respect to the road surface.Type: GrantFiled: June 14, 1996Date of Patent: May 19, 1998Assignee: Amalgamated Consulting Engineers of South Africa (Proprietary) Ltd.Inventor: David Lechtman

Patent number: 5621195Abstract: In a system for determining the spacing between axles on a vehicle, problems associated with the determination in a stop-and-go situation are overcome with a sensor array system wherein a first sensor is spaced from an array of sensors by a predetermined distance. The total length of the span of all the sensors must be greater than largest axle spacing on the vehicle to be measured. When two axles simultaneously trigger sensors, those triggered sensors' positions are sent to a computer and the axles spacing is computed and recorded. The system operates independently of the speed of the vehicle.Type: GrantFiled: June 7, 1995Date of Patent: April 15, 1997Assignee: International Road Dynamics Inc.Inventors: Brian Taylor, Terry Bergan

Patent number: 5585604Abstract: A method of determining a load measurement value in dynamic weighing of an object passing over a weighing platform supported by load-sensing means generating a load-dependent weighing signal (S) which rises from a basic level to a peak level, to subsequently fall to the basic level. An at least approximative signal peak value (S.sub.peak) is determined as representing the weighed load. The weighing signal is integrated at least during a time interval (t.sub.1 -t.sub.5) about the point where the signal peak value is determined in order to produce a summation result, the time interval being recorded as a measurement time factor (M). Further, a form factor (F) for the weighing signal is calculated in the form of the ratio of the summation result, i.e., the integrated area under the weighing signal (S) for the time interval (t.sub.1 -t.sub.5), to a corresponding rectangular area that would be obtained in static weighing, i.e., the product of a peak value and the above time interval.Type: GrantFiled: December 3, 1993Date of Patent: December 17, 1996Assignee: Frontec Lulea ABInventor: Lauri Holm
