Abstract: A leakage-sensing device for installation adjacent to a pipeline configured for conveying liquid or gaseous chemical materials. The leakage-sensing device comprises a length of cable configured to transmit and back-reflect signals.  The cable is communicable with a signal-measuring device. The entire length of cable is encompassed by a torsioned and tensioned coiled biasing means. The cable and the torsioned and tensioned coiled biasing means are embedded in a chemically frangible casing material. The chemically frangible material is selected for its structural instability when contacted with the selected chemical material to be conveyed within the pipeline thereby releasing the torsioned and tensioned biasing means which subsequently imparts bending and/or twisting and/or elongating and/or contracting forces to the cable thereby causing the cable to physically interfere with and/or deform and/or break the transmission and back-reflection of signals along the cable.

Abstract: A method and apparatus for estimating oscillator signal variation due to temperature and for providing an estimated frequency to a GPS receiver in order to assist the GPS receiver to acquire the signals quickly is disclosed. A temperature sensor is closely thermally coupled with the crystal oscillator in the GPS receiver and during GPS tracking mode, when the error in the oscillator signal is known with precision, outer bounds of TCXO frequency at given temperatures are maintained, which may correspond to rising and falling temperature conditions. During acquisition mode, an estimated frequency value is provided to the GPS receiver based on a determined average of these bounds. Optionally, an uncertainty factor associated with the frequency estimated may also be provided. The two bounds take into account the hysteresis effects of the oscillator signal drift due to temperature so that a more accurate initial frequency estimate can be provided to the GPS receiver, thus reducing its average time to first fix.

Abstract: A robust computational secret sharing scheme that provides for the efficient distribution and subsequent recovery of a private data is disclosed. A cryptographic key may be randomly generated and then shared using a secret sharing algorithm to generate a collection of key shares. The private data may be encrypted using the key, resulting in a ciphertext. The ciphertext may then be broken into ciphertext fragments using an Information Dispersal Algorithm. Each key share and a corresponding ciphertext fragment are provided as input to a committal method of a probabilistic commitment scheme, resulting in a committal value and a decommittal value. The share for the robust computational secret sharing scheme may be obtained by combining the key share, the ciphertext fragment, the decommittal value, and the vector of committal values.

Abstract: Systems and methodologies are described that facilitate defining and utilizing hopping patterns to transmit broadband pilot signals in a wireless communications network. Portions of bandwidth can be dedicated to transmitting the broadband pilot data, and patterns can be utilized to hop across frequencies in given time periods to effectively utilize the entire dedicated bandwidth. Moreover, the periodicity for transmitting the data is configurable to allow devices requiring additional scheduling (e.g., high activity devices) to transmit the broadband pilot data more frequently. The hopping patterns can also hop across cyclic shifts of the patterns to provide optimum diversity for transmitting broadband pilot signals.
