The Open Radar Data Acquisition (ORDA) subsystem replaces the current WSR-88D Radar Data Acquisition subsystem with improved receiver and signal processing hardware and with improved user interface, signal processing and diagnostics software. This paper will discuss the input data from the digital receiver, the ORDA signal processing, and the data output from the ORDA hardware. Specifications of the ORDA digital receiver will be presented. The paper outlines the critical radar signal processing flow and provides analysis of new spectrum width computations and clutter filtering schemes used in the ORDA system. Where appropriate, ORDA performance enhancements, data quality improvements and reliability and maintenance improvements will be highlighted.

This paper presents a new adaptive mobility-aware MAC protocol for sensor networks (MS-MAC). The protocol uses any change in received signal level as an indication of mobility and, when necessary, triggers the mobility handling mechanism. By doing this way, the new mobility-aware MAC protocol can work very energy-efficiently when the network is stationary, whereas it can maintain some level of network performance when there are mobile sensors.

SiftGPU is an implementation of SIFT [1] for GPU. SiftGPU processes pixels parallely to build Gaussian pyramids and detect DoG Keypoints. Based on GPU list generation, SiftGPU then uses a GPU/CPU mixed method to efficiently build compact keypoint lists. Finally keypoints are processed parallely to get their orientations and descriptors.

This approach, we feel, came very close to obtaining an image from the camera OV7620. Before we tried to capture a camera signal, we successfully transferred a test image from the FPGA s onboard RAM modules through RS232 to the PC program. This file do it.

Commercially available active noise control headphones rely on fixed analog controllers to drive "anti-noise" loudspeakers. Our design uses an adaptive controller to optimally cancel unwanted acoustic noise. This headphone would be particularly useful for workers who operate or work near heavy machinery and engines because the noise is selectively eliminated. Desired sounds, such as speech and warning signals, are left to be heard clearly. The adaptive control algorithm is implemented on a Texas Instruments (TI™ ) 1 TMS320C30GEL digital signal processor (DSP), which drives a Sony CD550 headphone/microphone system. Our experiments indicate that adaptive noise control results in a dramatic improvement in performance over fixed noise control. This improvement is due to the availability of high-performance programmable DSPs and the self-optimizing and tracking capabilities of the adaptive controller in response to the surrounding noise.

The TJA1040 is an advanced high speed CAN transceiver for use in automotive and general industrial applications. It supports the differential bus signal representation described in the international standard for in-vehicle high speed CAN applications (ISO11898). CAN (Controller Area Network) is the standard protocol for serial in-vehicle bus communication, particularly for Engine Management and Body Multiplexing. The TJA1040 provides a Standby mode, as known from its functional predecessors PCA82C250 and PCA82C251, but with significantly reduced power consumption. Besides the excellent low-power behavior the TJA1040 offers several valuable system improvements. Highlights are the absolute passive bus behavior if the device is unpowered as well as the excellent EMC performance.
