      <title>Universal Display and Controller for Multiplexed Systems</title>
      <link>https://trid.trb.org/View/1776660</link>
      <description><![CDATA[With today's trend of using multiplexed systems in mobile equipment comes the requirement for a Universal Display and Controller. These Universal Display Controllers (UDC) are used as a means of displaying information to the user issued to and received from the multiplexed systems. The UDC considered is a DOS-based unit allowing for ease of programming and customization for multiple OEM's. A PCMCIA interface is provided to download the functionality of the UDC, in addition to being used to retrieve logged data and configure nodes.Since the UDC's are located in a harsh environment, careful attention must be given to the wide ambient operating temperatures, sunlight readability, emissions, and other considerations unique to the environment. One of the most critical components of such a device is the display, which must survive these conditions and perform to the stringent requirements of today's equipment. The UDC discussed in this paper uses a Planar electroluminescent ¼-VGA display. This paper discusses the criteria for selecting a display component for these applications.]]></description>

      <title>Structured-Compressed-Sensing-Based Impulsive Noise Cancelation for MIMO Systems</title>
      <link>https://trid.trb.org/View/1480304</link>
      <description><![CDATA[In this paper, the powerful signal processing theory of structured compressed sensing (SCS) is exploited to overcome the challenge of impulsive noise (IN) cancellation in multiple-input multiple-output (MIMO) systems. To the best of the authors’ knowledge, the SCS theory is adopted for the first time for IN elimination, bridging IN mitigation and MIMO systems for its potential applications in vehicular-related communications. In achieving the SCS-based IN cancellation, the measurements matrix of the IN is first obtained from the null subcarriers in the MIMO system specified by the IEEE 802.11 standards series. The SCS optimization framework is then formulated through the proposed spatially multiple measuring method, by fully exploiting the spatial correlation of the IN signals at different receive antennas. To efficiently reconstruct the IN signal, an enhanced SCS-based greedy algorithm, structured <italic> a priori</italic> aided sparsity adaptive matching pursuit, is proposed, which significantly improves the accuracy and robustness compared with the state-of-the-art methods. Theoretical analysis is presented to guarantee the convergence and the performance error bound of the proposed greedy algorithm. Computer simulations validate that the proposed scheme outperforms the conventional ones over the wireless MIMO channel.]]></description>

      <title>A Novel Blockwise PAPR Minimization Algorithm for Connected Vehicles</title>
      <link>https://trid.trb.org/View/1427595</link>
      <description><![CDATA[In this paper the authors present a novel algorithm which minimizes peak-to-average power ratio (PAPR) of the orthogonal frequency division multiplexing (OFDM) signal used in IEEE 802.11p like transmission. The proposed algorithm is an extension of the widely known selected mapping (SLM) algorithm. Its novelty relies on performing PAPR minimization jointly in blocks of a few OFDM symbols and transmitting on side information usually required by the SML algorithm on pilot positions. Simulation results prove the usefulness of the proposed algorithm.]]></description>

      <title>Traffic-Aware Online Network Selection in Heterogeneous Wireless Networks</title>
      <link>https://trid.trb.org/View/1395602</link>
      <description><![CDATA[The authors focus on the network selection problem in heterogeneous wireless networks. Many traditional approaches select the best network according to quality of service (QoS)-related criteria, which neglects diverse user demands. The authors aim to select networks maximizing the quality of experience (QoE) of users. When the availability and dynamics of network state information (NSI) are considered, most of the existing approaches cannot make effective selection decisions since they are vulnerable to the uncertainty in NSI. To address this issue, the authors introduce the idea of online learning for network selection. In this paper, the authors formulate the network selection problem as a continuous-time multiarmed bandit (CT-MAB) problem. A traffic-aware online network selection (ONES) algorithm is designed to match typical traffic types of users with respective optimal networks in terms of QoE. Moreover, the authors found that the correlation among multiple traffic network selections can be exploited to improve the learning capability. This motivates the authors to propose another two more efficient algorithms: the decoupled ONES (D-ONES) algorithm and the virtual multiplexing ONES (VM-ONES) algorithm. Simulation results demonstrate that the authors ONES algorithms attain around 10% gain in QoE reward rate over nonlearning-based algorithms and learning-based algorithms without QoE considerations.]]></description>

      <title>Piezoresistive Strain Sensors and Multiplexed Arrays for Transportation Infrastructures</title>
      <link>https://trid.trb.org/View/1239161</link>
      <description><![CDATA[During Year 5 of Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU), Infrastructure Technology Institute researcher Professor Yonggang Huang collaborated with researchers at University of Illinois to engineer stretchable and flexible piezoresistive strain sensors and multiplexed arrays for advanced structure health monitoring of transportation infrastructures. The large, flexible and high-sensitivity sensor arrays enable rapid, accurate and robust measurement of strain distribution on any surface.  This may lead to accurate damage assessment of transportation infrastructures (e.g., bridges, highways) and prediction of service life, which is important to the highway structures portion of National Strategy of Surface Transportation Research identified by United States Department of Transportation research goals. The authors have developed materials, integration strategies, mechanical models and system demonstrations of distributed networks of piezoresistive strain sensors based on ultrathin single-crystalline silicon membranes on thin plastic substrates (i.e. polyimide).  Such systems offer high sensitivity (i.e. piezoresistive coefficient or gauge factor) of single-crystalline silicon while providing lightweight construction and mechanical flexibility. By using Wheatstone bridge configurations for the sensors and coupling them to multiplexing diodes, this technology can be scaled to large-area, integrated monitors with spatial mapping capabilities that also naturally provide compensation for variations in temperature.  They overcome the limitations of current sensors, and thereby opening up new opportunities for structural health monitoring of transportation infrastructures.]]></description>

      <title>FORMALIZATION OF DIGITAL CIRCUITS USING THE B METHOD</title>
      <link>https://trid.trb.org/View/729532</link>
      <description><![CDATA[The aim of this paper is to show how it is possible to combine the advantages of the B method in order to design secure digital circuits that may be easily developed and do not need a design test. The circuit design may be based on the libraries of well-known circuit design language such as VHDL. The goal here is to make use of the B method to produce the electronic or numeric circuits. First, the circuit specifications are written in the abstract machine. The refinement direction is determined by the basic elements that are used to construct the desired circuit, so the designer can orient the development to the needed level. This level can be found as a basic library in B. It is demonstrated how VHDL packages can be translated as B circuit components for giving the designer a high-level view. Using this approach, one can develop a circuit of which each part of the specification parts has already been proven to be correct.]]></description>

      <title>WHAT COST VIDEO?</title>
      <link>https://trid.trb.org/View/693819</link>
      <description><![CDATA[This article considers the cost implications and the technology involved in video multiplexing and transmission, used in surveillance equipment. Analogue Frequency Division Multiplexing systems have been effective in processing a large number of signals from a remote site to a central location. Third-generation systems of this type, allowing system expansion and offering multiple data channels, are the cheapest but still too costly for smaller applications. The latest generation of digital video multiplexers offers real-time video transmission and costs much less. The author describes the capabilities of 10-bit and 8-bit video and points out that the 10-bit system is not necessary and costs more. The latest 8-bit digital generation multiplexers are available in four-channel and eight-channel versions and can be used to build up to sixty-four channels. They cost less and offer efficient use of space, can support comprehensive remote configuration and monitoring, and provide very high performance video and audio transmission.]]></description>

      <title>NEW VEHICLE DATA BUS ARCHITECTURE AND IN-VEHICLE INFORMATION SYSTEM EVALUATION PLATFORM FOR INTELLIGENT TRANSPORTATION SYSTEMS MODULES</title>
      <link>https://trid.trb.org/View/542024</link>
      <description><![CDATA[An increasing number of intelligent transportation systems (ITS) after-market systems present a set of in-vehicle installation and use problems relatively unique in the history of automobile use.  Many automobile manufacturers would like to offer these new state-of-the-art devices to customers, but are hampered by the current design cycle of new cars.  While automobile manufacturers are indeed using multiplex buses [the automotive equivalent of a computer local area network (LAN)], problems remain because manufacturers are not converging on a single bus standard.  A new dual-bus architecture to address these problems is presented with an in-vehicle information system (IVIS) research platform on which the principles embodied in the ITS data bus architecture can be evaluated.  The dual-bus architecture has been embodied in a proposed Society of Automotive Engineers (SAE) standard, with support from both automobile and consumer electronics manufacturers.  The architecture and a reference model for the interfaces and protocols of the new bus are presented and described.  The goals of the ITS data bus are to be inexpensive and easy to install, and to provide for safe and secure functioning.  These high-level goals are embodied in the proposed standard.  The IVIS development platform comprises a number of personal computers (PCs) linked via ethernet LAN, with a high-end PC serving as the IVIS computer.  In this LAN, actual devices can be inserted in place of the original PC that emulated them. This platform will serve as the development and test bed for an ITS data bus conformity test, the SAE standard for which is also being developed.]]></description>

      <title>INTEROPERABLE NETWORKED CONTROL FOR RAIL TRANSIT SYSTEMS WITH LONWORKS TECHNOLOGY</title>
      <link>https://trid.trb.org/View/477413</link>
      <description><![CDATA[Multiplexed buses are necessary to reduce the complexity of wiring electronic control systems within and across rail cars and locomotives today, and to allow the addition of more electronic sensors and actuators to upgrade existing mechanical systems to electromechanical ones.  Locomotives and cars are assembled by integrators who obtain components and sub-assemblies from multiple suppliers.  Traditionally, different integrators have specified different buses.  As the number of systems with distributed sensors and actuators has increased and as the demand for smart trains has increased, standardization of multiplexed bus schemes has become necessary.  LONWORKS control networks offer a low-cost, widely-accepted and well-supported solution for multiplexing in trains.  Already, several onboard and wayside applications have been implemented.]]></description>

      <title>SYSTEM CONCEPTS FOR SERIAL DATA COMMUNICATIONS IN CARS</title>
      <link>https://trid.trb.org/View/373339</link>
      <description><![CDATA[In the past, discussions concerning automotive networks have been dedicated mostly to the protocol and the components used.  However, it is necessary to spend some effort in an investigation on the automobile as a complete electronic system in itself.  A system concept for an in- vehicle multiplex wiring network using the CAN- protocol is presented, covering the topics: requirements on the in- vehicle network regarding robustness against faults; concept for the behaviour of the total system as the result of the behaviour of all electronic subsystems (network members); and, required hardware for different approaches.

      <title>ADVANCED ENGINEERING MEASUREMENT AND INFORMATION SYSTEMS OF FUTURE VEHICLE WIRING SYSTEMS - MULTIPLEX</title>
      <link>https://trid.trb.org/View/373340</link>
      <description><![CDATA[Due to the possibilities of modern electronics the conventional vehicle wiring system can be completely redesigned in a new serial structure.  The Robert Bosch company has developed CAN (Controller Area Network) for serial data communication.  This protocol is already used in control units with high speed data transmission and is being put forward worldwide as a proposed standard by the International Standardization Organisation (ISO).  For slower Multiplex systems a special CAN unit (basicCAN) has been developed with considerably simpler hardware structure but with an identical protocol.  A comparison between both systems shows that serial structures can be used in future with more and more advantages. (A) For the covering abstract of the conference see IRRD 850768.]]></description>

      <title>MULTIPLEXED WIRING APPLICATIONS USING SMART-POWER HALL-EFFECT SENSING</title>
      <link>https://trid.trb.org/View/313870</link>
      <description><![CDATA[The increasing use of sensors in automotive applications has created a wiring nightmare which it is proposed to minimise by using wire multiplexing techniques.  The system described involves an inexpensive magnetic sensor ic that can directly respond to interrogations by the master controller and does not require remote controller board. New technology has been developed to combine cmos devices and bipolar transistors on the same substrate as a hall transducer.  Sensor operation is described in detail with explanatory diagrams.  A maximum of 30 active sensors can exist on a bus and a sequential addressing scheme reduces sensor complexity.  New fabrication procedures are described which were necessary for the design.  The size and complexity of the logic circuitry required high-density, low-current complementary logic and had in addition to be merged with hall transducer manufacturing technology.  The merging of technologies provides potential solutions to several longstanding problems and the author suggests applications in speed monitoring and twilight sensing.]]></description>

      <description><![CDATA[In order to provide road maintenance departments with information on current weather conditions at parts of the road system particularly exposed to skidding risks, a device has been produced which records meteorological data of special relevance, such as air and ground temperature and humidity.  Meteorological data are recorded at certain preselected intervals of time (for example, every half hour) and the last eight readings are retained in a memory.  The information is accessible via the telephone network and is given in verbal form, so that no special equipment is required in order to receive it.  When telephoning to the weather station the current data are obtained first, followed by the last eight readings.  The necessary word stock is stored in digital form and digitalization takes place via delta modulation. (TRRL)]]></description>
