    Software applications that require a high learning curve, a mountain of documentation, and weeks of training should be things of the past. Today's applications need to be simple to learn and to use. The human/computer interface should be intuitive and consistent. Context sensitive help should be available to keep the user on track. This paper provides some guidelines for taking commercial world concepts and applying them to the Automatic Test Equipment world. Examples included are from the Integrated Maintenance Information System (IMIS).<> View full abstract»

  • Magnetically inflatable SPS with energy storage capability

    Publication Year: 1995 , Page(s): 9 - 14

    A new approach to superconductive magnetic energy storage (SMES) for solar power satellite (SPS) with inherent rigidity is introduced in this paper. The rigidity of this SMES originating from the electromagnetic forces within it, can eliminate the need for mechanical building blocks for support structure. This force can also be used for the deployment of the system in space. In addition, the storage capability of the system allows its use in low Earth orbit (LEO) which reduces the launching and transmission costs. The paper also discusses the basic design and the operation of the proposed SPS system View full abstract»

  • New architectures for space power systems

    Electric power generation and conditioning have experienced revolutionary development over the past two decades. Furthermore, new materials such as high energy magnets and high temperature superconductors are either available or on the horizon. Our work is based on the premise that new technologies are an important driver of new power system concepts and architectures. This observation is borne out by the historical evolution of power systems both in terrestrial and aerospace applications. This paper introduces new approaches to designing space power systems by using several new technologies. Two new architectures are introduced: the current source current intensive system and the articulate system. Basic characteristics of these systems have been investigated. Some aspects of the articulate system architecture, as discussed in this paper can be implemented in the short term. Flexible AC transmission systems which are now undergoing rapid development and implementation, can be regarded as a subset of the family of control methodologies which constitute the realm of articulate systems View full abstract»

  • Patent claims-How to keep track of them

    Publication Year: 1995 , Page(s): 32 - 33

    The claims are a vital part of every patent disclosure, but can be confusing for a non-lawyer to read and understand. A patent disclosure includes, among other things, a description of the embodiment which reads like a technical article, and a set of claims, which reads like a legal document: the claims often depend on each other in a complicated way. While preparing material for a UK, US and Canadian patent with my patent attorney, I have found the claims to be the most difficult to keep organised: it is only too easy to leave something out, or to get the dependencies mixed up. The author has found it useful to summarise the claims in tabular form, and a simple dependency table is given View full abstract»

  • An experiment with an S-band radar using pulse compression and range sidelobe suppression for meteorological measurements

    A major technology barrier to the application of pulse compression for the meteorological functions required by a next generation ATC radar is range/time sidelobes which mask and corrupt observations of weak phenomena occurring near areas of strong extended meteorological scatterers. Techniques for suppressing range sidelobes are well known but without prior knowledge of the scattering medium's velocity distribution their performance degrades rapidly in the presence of Doppler. Recent investigations have presented a “doppler tolerant” range sidelobe suppression technique. The thrust of the work described herein is the extension of previous simulations to actual transmitted dispersed/coded waveforms using the S-band surveillance radar located at Rome Laboratory Surveillance Facility. The objectives of the experiment are: 1) to extend the verification of the simulation of the Doppler tolerant technique; and 2) to demonstrate that the radar transmitter, waveform generator, and receiver imperfections do not significantly degrade resolution, performance or reliability of meteorological spectral moment estimates View full abstract»

  • Sunlight viewable electroluminescent displays for military application

    A new advanced type of high ambient viewing AC electroluminescent display has been developed incorporating a combination of high contrast and high brightness techniques. The improvement in the contrast is achieved by a black absorption layer within the thin film structure. Improvement in the brightness is attributed to increasing the refresh rate by an order of magnitude. This can only be accomplished by an order of magnitude decrease in front electrode impedance with the use of a new metalized structure to reinforce the ITO electrodes and lower their resistance View full abstract»

  • Perspective on ultracapacitors for electric vehicles

    Recent advances in performance of chemical double layer capacitors (DLC) with aqueous and non-aqueous electrolytes have made it possible to seriously consider them for commercialization. Non-aqueous (organic) carbon based laboratory monopolar devices have recently met key U.S. Department of Energy (DoE) mid-term specifications (> 5 WNkg, >500 W/kg and >100,000 life cycles) for load-leveling electric vehicles batteries. All DLC technologies currently under development by DoE are discussed. Each technology has distinct advantages and none are clear winners at this time. A study has been completed by the General Electric Company on the interface electronics needed to best utilize the energy of capacitors for load-leveling batteries. System costs are presented based on this study, several battery technologies, and capacitor projections View full abstract»
