Patent number: 6459050Abstract: An apparatus and method for converting in-ground static weighing scales for vehicles to weigh-in-motion systems. The apparatus upon conversion includes the existing in-ground static scale, peripheral switches and an electronic module for automatic computation of the weight. By monitoring the velocity, tire position, axle spacing, and real time output from existing static scales as a vehicle drives over the scales, the system determines when an axle of a vehicle is on the scale at a given time, monitors the combined weight output from any given axle combination on the scale(s) at any given time, and from these measurements automatically computes the weight of each individual axle and gross vehicle weight by an integration, integration approximation, and/or signal averaging technique.Type: GrantFiled: September 20, 1999Date of Patent: October 1, 2002Assignee: UT-Battelle, Inc.Inventors: Jeffrey D. Muhs, Matthew B. Scudiere, John K. Jordan

Patent number: 6002501Abstract: An optical time-domain reflectometer (OTDR) launches pulses of light into a link or a system of multiplexed links and records the waveform of pulses reflected by the seals in the link(s). If a seal is opened, the link of cables will become a discontinuous transmitter of the light pulses and the OTDR can immediately detect that a seal has been opened. By analyzing the waveform, the OTDR can also quickly determine which seal(s) were opened. In this way the invention functions as a system of active seals. The invention is intended for applications that require long-term surveillance of a large number of closures. It provides immediate tamper detection, allows for periodic access to secured closures, and can be configured for many different distributions of closures. It can monitor closures in indoor and outdoor locations and it can monitor containers or groups of containers located many kilometers apart.Type: GrantFiled: June 30, 1997Date of Patent: December 14, 1999Assignee: Lockheed Martin Energy Research Corp.Inventors: D. Barton Smith, Jeffrey D. Muhs, Chris A. Pickett, D. Duncan Earl

Patent number: 5998741Abstract: This system and method of operation weighs and characterizes a moving vehicle traveling on a roadway. The moving vehicle travels across a weight transducer and first and second switching devices. The transducer provides a first set of output signals indicative of vehicle tire loading. The switching devices provide second output signals indicative of vehicle speed and characterization. Processor means receive the first and second output signals and characterize the vehicle; calculate the vehicle speed and calculate the vehicle weight by integrating the second output signals and combining with the vehicle speed.Type: GrantFiled: April 29, 1999Date of Patent: December 7, 1999Assignee: Lockheed Martin Energy Research Corp.Inventors: David L. Beshears, Gary J. Capps, John K. Jordan, John V. LaForge, Jeffrey D. Muhs, Robert N. Nodine, Matthew B. Scudiere, Cliff P. White

Patent number: 5627934Abstract: A concentric core optical fiber provides for the simultaneous but independent transmission of signals over a single optical fiber. The concentric optical fiber is constructed of a single-mode or multimode inner optical fiber defined by a core and a cladding of a lower index of refraction than the core and an outer optical fiber defined by additional cladding concentrically disposed around the cladding and of an index of refraction lower than the first mentioned cladding whereby the latter functions as the core of the outer optical fiber. By employing such an optical fiber construction with a single-mode inner core or optical fiber, highly sensitive interferometric and stable less sensitive amplitude based sensors can be placed along the same length of a concentric core optical fiber.Type: GrantFiled: August 3, 1994Date of Patent: May 6, 1997Assignee: Martin Marietta Energy Systems, Inc.Inventor: Jeffrey D. Muhs

Patent number: 5568582Abstract: A fiber optic connector and method for connecting composite materials within which optical fibers are imbedded. The fiber optic connector includes a capillary tube for receiving optical fibers at opposing ends. The method involves inserting a first optical fiber into the capillary tube and imbedding the unit in the end of a softened composite material. The capillary tube is injected with a coupling medium which subsequently solidifies. The composite material is machined to a desired configuration. An external optical fiber is then inserted into the capillary tube after fluidizing the coupling medium, whereby the optical fibers are coupled.Type: GrantFiled: October 13, 1994Date of Patent: October 22, 1996Assignee: Martin Marietta Energy Systems, Inc.Inventors: Slobodan Rajic, Jeffrey D.

Patent number: 5381492Abstract: A fiber optic vibration sensor utilizes two single mode optical fibers supported by a housing with one optical fiber fixedly secured to the housing and providing a reference signal and the other optical fiber having a free span length subject to vibrational displacement thereof with respect to the housing and the first optical fiber for providing a signal indicative of a measurement of any perturbation of the sensor. Damping or tailoring of the sensor to be responsive to selected levels of perturbation is provided by altering the diameter of optical fibers or by immersing at least a portion of the free span length of the vibration sensing optical fiber into a liquid of a selected viscosity.Type: GrantFiled: February 15, 1994Date of Patent: January 10, 1995Assignee: Martin Marietta Energy Systems, Inc.Inventors: Joseph B.

Patent number: 5374821Abstract: Fiber optic sensing means for the detection and measurement of events such as dynamic loadings imposed upon elastic materials including cementitious materials, elastomers, and animal body components and/or the attrition of such elastic materials are provided. One or more optical fibers each having a deformable core and cladding formed of an elastomeric material such as silicone rubber are embedded in the elastic material. Changes in light transmission through any of the optical fibers due the deformation of the optical fiber by the application of dynamic loads such as compression, tension, or bending loadings imposed on the elastic material or by the attrition of the elastic material such as by cracking, deterioration, aggregate break-up, and muscle, tendon, or organ atrophy provide a measurement of the dynamic loadings and attrition.Type: GrantFiled: June 30, 1993Date of Patent: December 20, 1994Assignee: Martin Marietta Energy Systems, Inc.Inventors: Jeffrey D. Muhs, Gary J. Capps, David B. Smith, Clifford P. White

Patent number: 5260520Abstract: Apparatus for weighing a vehicle in motion is provided by employing a plurality of elongated fiber-optic sensors defined by an optical fiber embedded in an encasement of elastomeric material and disposed parallel to each other on the roadway in the path of moving vehicles. Each fiber-optic sensor is provided with contact grid means which can be selectively altered to provide the fiber-optic sensors with sensitivities to vehicular weight different from each other for weighing vehicles in an extended weight range. Switch means are used in conjunction with the fiber-optic sensors to provide signals indicative of the speed of the moving vehicle, the number of axles on the vehicle, weight distribution, tire position, and the wheelbase of the vehicle. The use of a generally N-shaped configuration of switch means also provides a determination of the number of tires on each axle and the tire footprint.Type: GrantFiled: April 2, 1992Date of Patent: November 9, 1993Assignee: Martin Marietta Energy Systems, Inc.Inventors: Jeffrey D. Muhs, John K. Jordan, Kenneth W. Tobin, Jr., John V. LaForge
