Abstract: A method and system pertaining to a dual antenna compensation algorithm is provided. A local area augmentation system may include a dual antenna system to receive signals from satellites. The system may switch between the antennas to receive signals, and the transition between the antennas should be seamless. Thus, phase variations between the antennas can be determined to correct for code phase variations, and hardware delays between the antennas can be determined to correct for delay differences in signals received from both antennas.

Abstract: The present invention is drawn to an electrically “closed” method and apparatus for transmitting and receiving data signals over a high voltage power line. Inductive coupling is employed for coupling and decoupling the data signal directly on to and off of a single power line wire. An exemplary device includes a high frequency inductive coupling toroid for data signals, a second (50-60 Hz) inductive coupling toroid for providing power, signal conditioning electronics for the receive and transmit signal, a fiber optics interface for electrical isolation purposes, and a weather-proof enclosure. In a preferred embodiment, the toroids are hinged for ease of installation on a power line. A pair of such couplings on either side of a fiber-optic isolator can be used to bridge transformers.

Abstract: An apparatus and method for assessing the signal strength, quality and sources of interference in a wireless network. A drive test is performed using a receiving scanner in a geographic area that contains a plurality of base stations within a carrier's wireless network. The receiver and companion logic measure, analyze and record synchronization channels across all the frequencies used by the local base station. Signal quality is computed and expressed in the form of RxQual. Multiple readings are taken in a brief time period (˜480 msec) thus an average, representative quality is assessed. Signal fading, degradation, and interference are calculated using corelative techniques, for each used frequency. If the signal quality level is insufficient, then a scan for adjacent channel and co-channel interference is done. The data and analyses are used by the carrier to fine tune the wireless network system.

Abstract: A selective blocker for targeted mobile terminals. A signal monitor determines when a targeted mobile terminal is transmitting a signal to a base station. A signal analyzer identifies characteristics of the terminal signal and a processor produces a blocking response based on one or more characteristics. The blocking response is transmitted to the targeted mobile terminal to block communications between the targeted mobile terminal and the base station using the minimum power needed to effectively block the terminal signal so as to limit interference with non-targeted mobile terminals.

Abstract: A synchronization channel detection method for cellular transmission is disclosed. Said method is based on an algorithm that adds coherent components and deriving an average of the components in a synchronization signal that is repetitively transmitted over a short period of time. This method achieves a detection gain as compared to correlation algorithms.

Abstract: Bipolar Gaussian pulses are utilized to modulate digital data to communicate information via standard power lines. The pulses are sent in a pulse train, at set intervals. Modulation is accomplished without use of a sinusoidal wave as a carrier. Data is transmitted via power lines while reducing the amount of radiated emissions, enhancing data security, and mitigating interference from other sources. Channel capacity is also maximized by channelization in code space.

Abstract: A system and method for securing intellectual property rights in distributed intellectual property. The present invention grants and polices rights in electronically distributed intellectual property. Use limitations are established by agreement by the content provider and the client. The use limitations are reflected in time-based, usage-based and player based component codes that are used to determine if the client is entitled to use the intellectual property. The present invention further protects the intellectual property from unauthorized use by encrypting the intellectual property with a key created from some or all of the component codes. As the component codes are known to both the client and the content provider, no key exchange is required by the present invention.

A first data signal is communicated with the power line. A conversion is made between the first data signal and a second data signal capable of being communicated wirelessly. The second data signal is wirelessly communicated with the wireless communication path.

Abstract: The fiber optic isolator of the present invention transports data signals between high voltage power lines and a communications interface device, bypassing a step down transformer to low voltage power. The communication interface device includes a low voltage power line as well as telecommunications and wireless interfaces. The signals are coupled and de-coupled off of a high voltage power line by a power line coupler. The fiber optic isolator gets the signals (in light form) and transports them to and from the communications interface device. This insulates the system from current flow between the high voltage power lines and the communications interface.

Abstract: RF digital information signals are interfaced with a medium voltage power line data channel. An interface circuit connects between the medium voltage and low voltage sides of a step-down power transformer. The interface circuit includes a metal oxide arrestor (MOV) and an opto-coupler. The MOV provides the needed capacitance and voltage rating without the bulk of a capacitor having similar capacitance and voltage rating. The opto-coupler provides an added margin of safety for coupling communications data while isolating the medium voltage power from the low voltage side of the transformer.

Abstract: Isolating data in a power line communications system. Although plural subscribers receive electric power distributed from a common distribution transformer, it is desirable to isolate their branch lines from one another when those branch lines are used to conduct data communications as a supplement to electric power delivery. This isolation of branch lines is implemented in a centralized way at the distribution transformer, or alternatively, in a distributed way at each subscriber's premises. These implementations are made using low pass filters (which pass the power but block the data) and power line communications routers or power line communications repeaters.
