A02-098 TITLE: MicroElectro-Mechanical Systems (MEMS) Cryo-coolers TECHNOLOGY AREAS: Sensors ACQUISITION PROGRAM: PM, Soldier Systems OBJECTIVE: The objective is the development of a micro-fluidic MEMS (Micro Electro-Mechanical Systems) cooling unit capable of continuously removing 500 mW from an infrared FPA housed in a vacuum enclosure, cooling it to at least 100K. The unit should be completely self-contained and use less power than an equivalent macro-mechanical cooler or TE cooler capable of removing the same amount of heat. DESCRIPTION: Mid wave and short wave infrared focal plane arrays are typically operated at cryogenic temperatures using large, mechanical Sterling cycle cryocoolers or, at higher operating temperatures, with multi-stage thermo-electric (TE) coolers. These coolers require significant amounts of power to operate; far more than the focal plane array (FPA) itself, and in the case of the mechanical cooler add a considerable amount of vibration. In addition, the mean time between failures (MTBF) for all cryogenically cooled sensors is dominated by the MTBF of the cryo-cooler. Recent advances in MEMS technologies, particularly micro-fluidics, make possible the development of closed-cycle gas coolers using Carnot, Stirling, Joule-Thomson, or reverse-Brayton refrigeration systems integrated onto a single silicon wafer not much bigger than the FPA itself. PHASE I: Develop conceptual or preliminary design that would lead to a successful demonstration of a micro-fluidic MEMS cooling unit capable of removing 500 mW, continuous, from an infrared FPA, cooling it to at least 100K. The unit should be completely self-contained and use less power than an equivalent macro-mechanical cooler or TE cooler capable of removing the same amount of heat. The final report should address power, and lifetime issues, as well as the vibration levels produced by any mechanical elements. PHASE II: Design, build, and demonstrate a micro-fluidic MEMS cooling prototype capable of continuously removing 500 mW from an infrared FPA housed in a vacuum enclosure, cooling it to at least 100K. PHASE III: The Phase III effort would involve commercialization of the MEMS cryo-cooler for all applications requiring the inexpensive removal of waste heat from electronic circuitry. MEMS cryocooler would be useful for spot cooling of any commercial electronic product such as microprocessors, DSP's, high sensitivity CCD's, etc. DUAL USE APPLICATIONS: MEMS cryocooler would be useful for spot cooling of any commercial electronic product such as microprocessors, DSP's, high sensitivity CCD's, etc. REFERENCES: 1) Bowman, L.

- Very high dynamic range to avoid harmonic and inter-modulation signals appearing to be valid primary users. - Special algorithms to help reject false detections, otherwise, excessive interference or insufficient amount of harvested spectrum. However, scanning fast is not a critical requirement, many bands with low usage and harvest these bands first. - Need special active probing methods in broadcast bands and in bands with low duty cycle as listening alone will not prevent interference to primary users. After developing the basic technique, a survey is required to determine the spectrum where the technique can be applied best. This can be done with spectrum utilization study. PHASE I: The first part of this phase will include the development of the basic concept of spectrum sharing. A simulation study is required to demonstrate the concept that will satisfy the above-mentioned requirement. The simulation model will demonstrate the concept for spectrum sharing technique for interfacing with DoD’s several radios such as SINCGARS, EPLRS etc. The second part of this phase will include a study to determine the existing spectrum utilization and determine in which band this technique can be utilized most efficiently. PHASE II: This phase will include the development of a prototype product and demonstrate the effective spectrum utilization concept with its direct application in DoD’s FCS. For this purpose, a qualitative study needs to be done to determine advantage of this technique in comparison with the existing techniques. PHASE III Commercial Application: In addition to its application in the combat network system in the military, this technology can be used in the wireless and mobile communication area where dynamically allocated spectrum techniques can increase the coverage areas and reduce intersystem interference. The technique will also have its application in the wireless LAN system where variable data rate transmission is related to the varying bandwidth. As a result in the same WLAN system, at any instant more spectrum can be allocated to the channel where more data transmission rate is required. In this way the performance of the network can be increased manifold. Homeland Defense Application: The technique can be applied for DoD's secured wireless communication by sharing commercial spectrum. This will increase the spectrum utilization efficiency and also provide more reliable wireless communication, both data and voice.

A02-100 TITLE: High Gain Antenna for Wireless Local Area Network (LAN) TECHNOLOGY AREAS: Information Systems ACQUISITION PROGRAM: PM Warrior Informaiton Network-Tactical (WIN-T) OBJECTIVE: To develop a high gain, small aperture, light weight, low cost antenna for wireless local area network (WLAN) and personal communication systems (PCS) on the battlefield. A Phase I prototyping effort would provide a proof-of-concept and a basis for the future development of high gain antennas in the 1.8 GHz to 6 GHz range. Low cost linear phased arrays have become possible with the development of ferroelectric phase shifters and continuous transverse stub (CTS) architectures. DESCRIPTION: Wireless LANs and PCS systems are becoming more useful for military applications as commercial off the shelf products are adapted to military environments. These military adaptations include improved security and ruggedization. Another important capability for battlefield operation is radio coverage. WLANs and PCS will be deployed in various terrain and foliage environments, so radio coverage should be adaptive. New low cost ferroelectric phase shifters in CTS configurations show promise for enabling electronic control of antenna gain patterns allowing adaptive radio coverage for changing battlefield situations. Wireless LANs will also be used for communication between transport aircraft for planning and rehearsal while enroute to deployment. These wireless LANs will pass digital information between C-130 aircraft in to maintain connectivity among command elements while in flight. Adaptive directivity and antenna pattern control could enhance connectivity between flying aircraft. In general, military wireless LANs should be capable of dynamic antenna gain control to perform in various battlefield situations. PHASE I: Provide high gain antenna designs for wireless LAN operation at 2.4 GHz to 2.5 GHz, 4.4 GHz to 4.5 GHz, and 5.7 GHz to 5.9 GHz, and 1850 MHz to 1990 MHz for PCS systems. Specify materials, dimensions, fabrication process, and cost. Illustrate expected performance with results from electromagnetic modeling. PHASE II: Fabricate, test and demonstrate antennas. Show performance gain compared to conventional antennas. Optimize antenna system designs for military and/or commercial applications. Resolve system issues, improve ruggedization, improve antenna control system, address installation and cost. Military application should address improved capability for battlefield operational radio coverage. The coverage should be adaptive as WLAN and PCS will be deployed in various terrain and foliage environments. These WLAN will pass information between C-130 aircraft to maintain connectivity among command elements while in flight for planning and rehearsal while enroute to deployment. PHASE III: Military use in wireless LANs in the tactical environment and in any area that the military or other government agency (to include homeland defense) needs to set up an ad-hoc network with reliable wireless communications through diverse terrain. Commercial use of this technology offers increases in antenna gain control, signal quality, and coverage in various public dispatching services in the field of medical, police and firefighting department.

The need for both low power protocols, as well as those that can be manufactured cheaply, is common to both military and civilian markets. The essential problems to be addressed are the design of integrated channel access and routing protocols that are suitable for implementation in hardware but yet provide both the functionality required as well as flexibility to operate in a number of different radio environments and applications. DESCRIPTION: Low power protocols have been studied for both channel access and network multi-hop routing, but not in an integrated fashion. In addition, most traditional low power protocols are not "customizable" to support differing environments, such as required bandwidth, node scalability, data delivery requirements, or link protocol. Specifically, the channel access methods and routing algorithms developed should be flexible enough to function in the civilian environment where latency and reliable data delivery may be of lessor importance than in a military environment. While there are no specific performance requirements for the channel access and routing algorithms to be designed and developed, a set of goals can be defined. For channel access, both asynchronous (or contention based) and synchronous (TDMA) channel mechanisms are of interest, with the desire to support both modes in a single network environment. Additionally, it is desired to support both reliable, and best effort data transfer at the link layer. The use of Forward Error Detection and Correction should also be considered. In addition, link metrics that address low power issues should also be defined and used. In the area of routing, it may be desirable have algorithms that can operate using a collection of different link metrics. The issue of network connectivity assessment should also be viewed in a low power environment. Congestion control mechanisms that are power aware are also of interest. Finally, network initialization (from a cold start) that is power aware is also a part of the overall problem to be addressed. HOMELAND DEFENSE STATEMENT: The VLSI protocol designs and implementations can be used in Homeland Defense. The sensor technology can be linked using these protocols in an efficient and affordable manner. The low cost and low power will enable large numbers of networked sensors to be deployed and to provide an enhanced level of security at airports and other transportation terminals. The affordability of the devices and components will allow them to be deployed in large numbers with little maintenance and other support for long periods of time. As these VLSI protocols are independent of the attached sensor technology, they may be used in a wide variety of sensor systems.

KEYWORDS: Protocols, Sensor Networks, VLSI, Communication Networks, Low Power VLSI A02-102 TITLE: Network Quality of Service (QoS) Forecasting for Multimedia TECHNOLOGY AREAS: Information Systems OBJECTIVE: Develop network infrastructure that can gather more timely and useful data with regard to current and anticipated network QoS to better facilitate multimedia applications use of network resources. Multimedia applications have both commercial use and Government use in military applications and the Homeland Security effort. DESCRIPTION: Improved information about current and near future network QoS will enable a new breed of agile multi-media applications. These applications will dynamically adapt to network conditions to seamlessly meet communication goals. A precondition for developing such agile applications is the technology for low-cost, high-quality network QoS predictions. This would include better predictions of network QoS at various timescales, particularly targeted at a range of multimedia applications, and better measures of network QoS that are more finely focused on specific multi-media application needs. Such prediction technology would include schemes for conveniently building network QoS-aware, agile multimedia applications. Improved QoS information might include more accurate estimates of delivery times as well as new kinds of metrics for classifying the network behavior. Techniques such as empirical measurements, e.g., network weather forecasting, and causal modeling could be extended to make use of the additional information. Real-world information could also be incorporated for longer range forecasting of network demands (military situation, anticipated impact of information warfare attack, sunspot activity, etc.). Multimedia applications could utilize the additional information in a variety of ways such as adapting the fidelity content based on anticipated quality of the network resource. Practical issues of how to adapt the IP and/or higher layer protocols to gather and provide this information will need to be addressed. PHASE I: This phase will provide a preliminary indication of the effectiveness of applying an improved network QoS forecasting approach. It will define candidate finer measures of quality appropriate to multimedia applications and use analytic or experimental methods to demonstrate the plausible usefulness of these measures as predictors for multimedia application functionality. PHASE II: This phase will design, implement and test the QoS approach in order to increase its effectiveness and to demonstrate it in a wider context. The testing will provide better insight into the effectiveness of the technology for multimedia applications. PHASE III: This phase will develop the technology for forecasting QoS so that can it be evaluated for its contribution in a military networking environment and in the ability to support more consistent effectiveness for commercial applications. In military networks, this technology will be used in planning which will model, predict or forecast the network infrastructure necessary to provide QoS for the deployment and conduct of military operations. Once military operations are active, this technology can be used to monitor, predict, forecast, and tailor changes to the communications network in support of the commander need for QoS for the military multimedia applications. For commercial networks, this technology can be used by network service providers to scale network assets for specific client needs for QoS for multimedia applications based on timescales and business cycles. This technology will impact the efficiency of the commercial networks. This Phase III technology development could be used to support the military and commercial applications adopted by the Federal Government's Homeland Security effort.

This technology could also be directly applicable to the JTRS communication system as well as any communication system for Homeland Security. DESCRIPTION: The goal of a true software radio is direct digitization of received signals followed by all-digital signal processing that is software controlled and reconfigurable. Towards that goal, a bandpass ADC technology, capable of direct sampling of RF signals is required. The frequency range of interest is 2-2000 MHz that includes most of Joint Tactical Radio System (JTRS) communication requirements. The ADC should have high linearity (spur-free dynamic range 80-100 dB) and high resolution (16 effective bits) for 10-100 MHz bandwidth. PHASE I: Feasibility analysis, concept formulation, and parameter optimization to show that a high spur-free dynamic range (SFDR) ADC front-end technology is capable of digitizing bandpass RF signals directly. The ADC is to be built and demonstrated in Phase II. PHASE II: Build and demonstrate a bandpass ADC using the results of the Phase I. PHASE III: a. Military Application: The resultant analog-to-digital converter (ADC) technology could be inserted into future JTRS radio family members as a pre-planned product improvement. This technology could also be directly applicable to any communication system for Homeland Security. b. Commercial Application: The bandpass ADC technology will find widespread use in commercial wireless communications, e.g., direct digitization of the entire 1930-1990 MHz band. This technology could also be directly applicable to any communication system for Homeland Security.
