摘要： A simple, inexpensive and highly efficient fuel cell has boundary structures made of a photo-sensitive material in combination with selective patterning. Printed circuit board (PCB) fabrication techniques combine boundary structures with two and three dimensional electrical flow path. Photo-sensitive material and PCB fabrication techniques are alternately or combined utilized for making micro-channel structures or micro stitch structures for substantially reducing dead zones of the diffusion layer while keeping fluid flow resistance to a minimum. The fuel cell assembly is free of mechanical clamping elements. Adhesives that may be conductively contaminated and/or fiber-reinforced provide mechanical and eventual electrical connections, and sealing within the assembly. Mechanically supporting backing layers are pre-fabricated with a natural bend defined in combination with the backing layers' elasticity to eliminate massive support plates and assist the adhesive bonding. Proton insulation between adjacent and electrically linked in-plane cell elements is provided by structural insulation within the central membrane.

摘要： Techniques for location-assisted wireless communication use real-time location(s) of wireless transceiver(s) together with stored location-indexed channel information to improve communication over a wireless channel between the transceiver(s). The stored channel information includes channel characteristics (e.g., average power, angle-of-arrival, and time delay of multipath components) that are substantially constant in time but vary gradually as a function of location. Current transceiver location(s) are obtained and used to retrieve stored channel characteristics corresponding to the location(s). The channel information may be used at either or both transceiver(s) to improve reception and/or transmission of signals propagating over the wireless channel. For example, reception may be improved by using path angle information to perform spatially structured reception, or using path delay information to perform temporally structured reception, e.g., to assign fingers to multipath components in a RAKE receiver and/or to track time delays of multipath components.

摘要： An improved surface plasmon resonance (SPR) sensor is provided based on direct measurement of the Goos-Hänchen effect. Sensor sensitivity is enhanced by selecting the thickness of the metallic layer of the SPR sensor to be close to a critical thickness dcr where the effect of the surface plasmon resonance on the Goos-Hänchen shift is most pronounced. Overall sensor sensitivity is surprisingly found to improve with this approach, even though the measurement is based on a second order effect (i.e., the Goos-Hänchen shift) instead of the first order reflectance change measured in conventional SPR sensor approaches. The invention is also applicable to sensors based on measurements of other non-specular reflection parameters, such as temporal shifts, frequency shifts, and/or angular shifts.
摘要翻译：基于Goos-Hänchen效应的直接测量，提供了改进的表面等离子体共振（SPR）传感器。传感器灵敏度通过选择SPR传感器的金属层的厚度来接近临界厚度d 而增强，其中表面等离子体共振对Goos-Hänchen位移的影响最显着。令人惊奇地发现，使用这种方法，总体传感器灵敏度可以改善，即使测量是基于二阶效应（即Goos-Hänchen移动）而不是在常规SPR传感器方法中测量的一阶反射率变化。本发明还可应用于基于其他非镜面反射参数（诸如时间偏移，频移和/或角位移）的测量的传感器。

摘要： In a complete network-in-a-box system acting as an enterprise network demarcation point, packets such as voice, video and data packets, are routed over common network connections, such as LAN and WAN. The packets are mapped from a public address field (such as an IP address) and port number to a private address field and port number, the mapping process typically being handled by a NAT (Network Address Translation). The packets are also prioritized, by marking the packets for priority queuing and routing, and configuring the bandwidths of the WAN traffic and the voice traffic to predetermined quantities and configuring the address fields of the voice devices. Simultaneous transmission of the various packets can be limited to predetermined quantities, typically by utilizing a CAC (Client Access Control). Secure firewalls are also included as well as a performance test client application that provides a defined workload generated across the WAN interface for capacity planning measurements and allows remote monitoring of the QoS (Quality of Service) data, such as latency, jitter, lost packets and MOS scores. Optionally, a simple, common remote management interface is included, allowing service providers to configure, upgrade and manage the system. Additionally, address fields can be provided to voice, video or data devices attached to a LAN port. VPN authentication and encrypted sessions can be tunneled through the firewall for access to an internal network by using a VPN terminator. For power outages and other emergency purposes, additional ports that connect to PSTN (Public Switched Telephone Network) analog telephone lines as well as other analog telephones or devices, can be provided. Another advantageous element is that most of the above components or features may be enabled or disabled.
摘要翻译：在作为企业网络分界点的完整的网络一体系统中，诸如语音，视频和数据分组之类的数据包通过LAN和WAN等公共网络连接进行路由。分组从公共地址字段（例如IP地址）和端口号映射到专用地址字段和端口号，映射过程通常由NAT（网络地址转换）处理。通过标记用于优先级排队和路由的分组，以及将WAN流量和语音流量的带宽配置为预定量并配置语音设备的地址字段，也优先分组。通常通过利用CAC（客户端访问控制）将各种分组的同时传输限制为预定量。还包括安全防火墙以及性能测试客户端应用程序，可提供跨WAN接口生成的定义工作负载，用于容量规划测量，并允许远程监控QoS（服务质量）数据，如延迟，抖动，丢失的数据包，以及 MOS分数。可选地，包括简单的通用远程管理界面，允许服务提供商配置，升级和管理系统。另外，可以将地址字段提供给连接到LAN端口的语音，视频或数据设备。 VPN身份验证和加密会话可以通过防火墙隧道通过VPN终结器访问内部网络。对于断电和其他紧急情况，可以提供连接到PSTN（公共交换电话网）模拟电话线以及其他模拟电话或设备的附加端口。另一有利的因素是上述组件或特征中的大多数可以被启用或禁用。

摘要： A method to detect and classify a structure of interest in a medical image is provided to enable high specificity without sacrificing the sensitivity of detection. The method is based on representing changes in three-dimensional image data with a vector field, characterizing the topology of this vector field and using the characterized topology of the vector field for classification of a structure of interest. The method could be used as a stand-alone method or as a post-processing method to enhance and classify outputs of a high-sensitivity low-specificity method to eliminate false positives.

摘要： A method of powering one or more electronic devices in a tire monitoring system using a tire pressure based energy scavenger is provided. With this method, a tire is rotated on a surface to generate pressure changes within the tire. These pressure changes are then converted into electrical energy with a transducer and the energy is stored. The electrical energy or stored electrical energy can then be used to power one or more electronic devices in a tire monitoring system, such as a tire pressure sensor, temperature sensor, acceleration profile sensor, and/or a tire wear monitor. A tire monitoring system with a tire pressure based energy scavenger is also provided.

摘要： Optical characterization of lateral features of a pattern is provided. A plane-wave optical response is calculated for each feature. At least one of these plane-wave responses is calculated from an effective optical property (e.g., a waveguide modal refractive index). Such effective optical properties depend on feature geometry and on intrinsic material optical properties. The plane-wave responses for each feature are combined to generate a modeled pattern response. By fitting the modeled pattern response to a corresponding measured pattern response, estimates for pattern feature parameters are obtained. The use of an effective optical property improves model accuracy, especially for features having a size on the order of a wavelength or less, without significantly increasing computation time.

摘要： A finite impulse response filter having tap weight rotation is provided, where each tap has a corresponding coefficient selector. Each coefficient selector includes N coefficients, where N is the number of taps. Each coefficient selector provides one of its corresponding coefficients as an input to a multiplier. Each multiplier also receives an input from a triggered track and hold tap. The tap coefficients are selected according to the time delay since the corresponding track and hold tap was most recently triggered. In this manner, the tendency of multiplier gain nonuniformity to degrade filter operation in the presence of tap weight rotation is reduced. In another embodiment, an offset selector is provided, to reduce the tendency of component offsets to degrade filter operation in the presence of tap weight rotation.
