Abstract: Systems and methods provide laser pulse equalization at different pulse repetition frequencies (PRFs). After initially pumping a lasing medium from a first pumping level to a peak pumping level, a controller may cause a pump source to continue pumping the lasing medium according to a pulse equalization pumping curve. The equalization pumping curve may be determined based on testing laser pulse parameters at different PRFs to achieve an optimal equalization result of the pulse parameters. The optimization metric used to evaluate various equalization pumping curves may include a consistency of the pulse energy level, peak power level, and/or pulse width of the laser under different PRFs. The equalization pumping curve may be a descending curve from the peak pumping level to the first pumping level. The equalization pumping curve may be a linearly declining curve, a substantially exponentially declining curve, a parametrically declining curve, or any other curve type.

IPC: E21B43/26
Filed: 2009-04-29
Abstract: There is provided a frac adapter configured to couple a frac tree to a wellhead component. The frac adapter may couple the frac tree to a casing head without a tubing head, thereby enabling the well to be fractured before the tubing head is installed. As a result, the tubing head used in well production may be pressure-rated for production pressures rather than for fracing pressures. The frac adapter may be coupled to or integral with the frac tree. In addition, a union-nut coupling may be employed to quickly and easily assemble and disassemble the frac adapter from the wellhead component, such as the casing head. The union-nut coupling may further enable the components to be pressure-tested before the fracturing process is initiated.

Abstract: Three interconnected methods of card-based fare collection at offline service access validation terminals are disclosed. The first method is characterized by storing in the terminals and periodically actualizing positive card lists and card activity data. This method is most pertinent to the public transit fare systems utilizing open-loop payment cards and vehicle-installed offline terminals. The second method is characterized by actualizing the terminals' data by way of data broadcasting or multicasting. This method improves performance of open-loop and closed-loop card systems implementing offline validations.  The third method is characterized by optimizing data broadcasting or multicasting by way of (i) breaking down the data into segments and terminals into groups, and (ii) transmitting the data segments to the terminal groups in order of priority.

IPC: H04W16/06

Abstract: A wireless communication network uses backhaul negotiation based upon static and dynamic resource assignment on jamming graphs. Static reuse factor design methods including fractional frequency reuse (FFR) are addressed. The jamming graph is used to summarize the interfering relationship between transmitters (nodes in the jamming graph). Negotiation-based algorithm is used to arrive at a static resource assignment so that a large reuse factor can be achieved while jamming scenario can be avoided. As a result of such algorithm, each transmitter is assigned some resources, over which traffic transmission can be done instantaneously to reduce the packet delay for short packets. Based on the result of static resource negotiation algorithm, a dynamic resource algorithm can be run, such that the resources assigned to different nodes can be share in a bursty traffic scenario to further reduce packet delay for larger packet size cases, while jamming be also avoided.

Abstract: In certain embodiments, a system for killing pests in an affected area includes a burner for heating a fluid. Heat exchanger units are placed within associated regions of the affected area. Each heat exchanger unit receives the fluid from the burner and emits heated air by transferring heat from the fluid to ambient air within the affected area. Air movers are positioned to circulate the heated air emitted by the heat exchanger units and prevent stratification of the heated air. A temperature difference between the fluid received by the heat exchanger units and the ambient air within the affected area results the affected area being raised to a target temperature greater than 122 degrees Fahrenheit.

Abstract: A method for decoding compressed data that has been encoded using a context model, each context having a context state corresponding to a probability estimate.  Each bin of the data has been encoded using the probability estimate corresponding to the context state for the context associated with that bin. At the decoder, for decoding a series of bins associated with a given context, an initial probability estimate is determined using an initial context state for the given context and the series of bins are decoded and reconstructed using that initial probability estimate. After the series is decoded, the context state is updated based on the reconstructed bins for the series to produce an updated context state for that context to be used in decoding a subsequence portion of the bitstream.
