  • Patent number: 7307547
    Abstract: A secure optical-communication traffic-preemption system and method is provided that securely communicates an identification code from an optical emitter to a traffic location. The optical emitter transmits light pulses that represent an encrypted code that is an encryption using a time-varying encryption key of at least an identification code. An optical detector situated at a traffic location receives the transmitted light pulses. Validation, including decryption using a time-varying decryption key, is attempted for the encrypted identification code represented within the received light pulses. In response to validating the included identification code, a traffic-preemption command is generated for a traffic light at the traffic location.

  • Patent number: 7307551
    Abstract: Delimiter lookup is accomplished using a processor permutation instruction. A 256-bit bitmap is defined and stored within two sixteen-byte registers. Each bit of the bitmap represents an eight-bit character occurrable within a character string, such as a section of eXtensible Markup Language (XML) code, and has a value indicating whether the character is a target character, such as a delimiter. The character string has a number of eight-bit characters at a corresponding number of positions. The first position within the character string at which one of the target characters occurs is determined, using the 256-bit bitmap and a processor permutation instruction. The first position within the character string at which one of the target characters occurs, as has been determined, is output.

  • Patent number: 7307565
    Abstract: A signal processing system matches, within a band of near out-of-band frequencies, the frequency response trends of a delta sigma modulator noise transfer function (NTF) and frequency response trends of a low pass finite impulse response (FIR) filter to provide noise attenuation in in-band frequencies and near out-of-band frequencies. More specifically, in at least one embodiment, the signal processing system matches, within the band of near out-of-band frequencies, a gradient trending toward increasing energy as the near out-of-band frequencies increase of the NTF with a gradient trending toward increasing attenuation by a FIR filter to improve attenuation of near out-of-band energy in an output signal of the signal processing system. Operation of the delta sigma modulator generates near out-of-band noise. Improving attenuation of the near out-of-band energy helps prevent the near out-of-band energy from being modulated into in-band frequencies, i.e. frequencies of a signal of interest.

  • Patent number: 7307569
    Abstract: Data throughput rates are increased in an optical fiber communication system without requiring replacement of the existing optical fiber in a link. Channel throughput is increased by upgrading the components and circuitry in the head and terminal of an optical fiber communication system link. Aggregate throughput in a fiber optic link is increased beyond the range of conventional Wavelength Division Multiplexed (WDM) upgrades, while precluding the necessity of replacing existing fiber plants. The increase in system throughput is achieved by using advanced modulation techniques to encode greater amounts of data into the transmitted spectrum of a channel, thereby increasing the spectral efficiency of each channel. This novel method of increasing transmission capacity by upgrading the head and terminal of the system to achieve greater spectral efficiency and hence throughput, alleviates the need to replace existing fiber plants.

  • Patent number: 7307575
    Abstract: Lower resolution and clutter-prone two-tone CW radars can have the displayed images dramatically improved by three techniques involved in the subject invention. The three techniques involved are the stepping of each of the multiple radars for readings at multiple frequencies, weighting the results to compensate for wall-induced distortions and differential image processing. In one embodiment, weights for each frequency counteract the distortion produced by particular wall. For differential image processing, temporal snapshots of the images are subtracted one from the other such that the result is only due to moving objects, thus to provide a dramatic display of the presence and position of moving individuals behind a wall.

  • Patent number: 7307580
    Abstract: Provided is a non-statistical method for compressing and decompressing complex SAR data derived from reflected energy. The method includes selecting a first FFT to provide a target ratio of pixel spacing to resolution. A second FFT is then selected which is smaller than the first FFT. The data is zero-padded to fill the second FFT and transformed to provide at least one transfer frequency. This transfer frequency is then transferred to the at least one remote site. At the remote site the second FFT is inverted to restore the data from the received transfer frequency. The restored data is then zero-padded again to fill the first FFT. The first FFT is then used to transform the zero-padded restored data to provide a data set of points with the target ratio of pixel spacing to resolution.

  • Patent number: 7307582
    Abstract: A method for determining a distance between a radar sensor and a reflection surface of a material comprising the following steps. The radar sensor is energized via a two-wire control loop which allows for data communication and an internal energy store. An echo profile is generated and analyzed to calculate the distance. During generation of the echo profile, the generation process is interrupted at least once to recharge the energy store via the two-wire control loop.

  • Patent number: 7307584
    Abstract: Methods and apparatus compress data, comprising an In-phase (I) component and a Quadrature (Q) component. Statistical characteristics of the data are utilized to convert the data into a form that requires fewer bits in accordance with the statistical characteristics. The data may be further compressed by transforming the data and by modifying the transformed data in accordance with a quantization conversion table that is associated with the processed data. Additionally, redundancy may be removed from the processed data with an encoder. Subsequent processing of the compressed data may decompress the compressed data in order to approximate the original data by reversing the process for compressing the data with corresponding inverse operations. Interleaved I and Q components can be processed rather than separating the components before processing the data. The processed data type may be determined by providing metadata to retrieve the appropriate quantization table from a knowledge database.

  • Patent number: 7307585
    Abstract: An aircraft aeroelasticity measurement system according to the invention can be used to perform in-flight wing twist measurements of an aircraft or any moving vehicle or structure on which its sensors can be mounted. The system includes a centralized processing unit, a reference navigation unit mounted in the aircraft body, a plurality of measurement navigation units mounted in the aircraft wings, and a global positioning system (“GPS”) receiver that generates GPS data for enhancing the accuracy of the navigation data. The system collects navigation data from the reference navigation unit and the measurement navigation units, generates navigation solutions from the navigation data, and performs a stochastic alignment and flexure estimation procedure to generate a corrected measurement solution that indicates the aeroelasticity of the aircraft. Wing twist and wing deflection information can be derived from the corrected measurement solution.

  • Patent number: 7307590
    Abstract: The present invention by propagates a traveling wave of electric current along a microstrip antenna structure rather than a standing wave. By loading an antenna with a series of capacitive gaps of the correct values, the shape of the electric current distribution can be tailored to suppress the resonant properties of the antenna, specifically the standing wave of electric current that normally forms along the antenna structure. A microstrip antenna having a “bulls-eye target” structure comprised of a center disk and concentrically larger capacitively coupled annular sections will tailor the shape of the electric current distribution to achieve a suppression of the resonant properties of the antenna, thereby increasing the antenna bandwidth.

The orthogonal drive may be time orthogonal or phase orthogonal. A location is determined based on near field response which may include propagation properties, which may include amplitude, phase, relative amplitude, or phase, or other properties. In one embodiment, multiple transmitters are utilized to determine the location of a single receiver.
