Abstract: A system, method and program for playing multiple, communal-card poker games simultaneously. A plurality of selectable starting hands of cards are presented to a participant. Each of the selectable starting hands represents a potential subset of a resulting poker hand, and does not of itself represent a playable hand. The participant selects one of the starting hands for use in all of the concurrently-played poker games. A plurality of communal-card flops are presented to the participant. The number of communal-card flops displayed corresponds to the number of poker games to be concurrently-played. A plurality of participant resulting poker hands are derived, one for each combination of the participant's selected starting hand and the plurality of communal-card flops. A plurality of remaining resulting poker hands are also derived, one for each combination of non-selected starting hands and each of the communal-card flops.

Abstract: Method and apparatus for evolving an object using simulated annealing and genetic processing techniques. In various embodiments, simulated annealing and genetic processing techniques are combined to evolve a computer-represented object. In each iteration an object is mutated in proportion to a mutation level, and the mutated object is evaluated relative to satisfaction of predetermined criteria. The mutation level is reduced with each iteration as the object approaches a final solution. Poorer-performing objects are selectively mutated or discarded based on a probabilistic function. As the object approaches a final solution, the probability of keeping and mutating poorer-performing objects is reduced.

Abstract: A system, apparatus and method for automatically limiting the thrust force applied to a drill string during an underground boring process, in order to prevent the deformation or collapse to the drill rods due to reaching the yield point of the rods. One or more drill string characteristics that have an impact on the yield point of the drill string, or portions of the drill string, are determined. The yield point of the drill string or portion is computed, where the yield point is computed as a function of the drill string characteristics. The thrust force imparted to the drill string is adjusted in response to the computed yield point.

Abstract: A system and method for controlling an underground boring tool involves the use of one or more of a gyroscope, accelerometer, and magnetometer sensor provided in or proximate the boring tool. The location of the boring tool is detected substantially in real-time. A controller produces a control signal substantially in real-time in response to the detected boring tool location and sensed parameters of a boring tool driving apparatus. The control signal is applied to the driving apparatus to control one or both of a rate and a direction of boring tool movement along the underground path. The gyroscope, accelerometer, and magnetometers may be of a conventional design, but are preferably of a solid-state design. Telemetry data is communicated electromagnetically, optically or capacitively between the navigation sensors at the boring tool and the controller via the drill string or an above-ground tracker unit.

A simulated table definition is hosted by a server and includes selected data definitions from the plurality of tables. Data extraction logic is hosted by the server and extracts data from the plurality of tables into memory of the server consistent with the simulated table definition and responsive to a request for access to the simulated table. Interface logic is also hosted by the server and is coupled to the data extraction logic. The interface logic transmits the extracted data to the requester consistent with the simulated table and returns for reuse the memory occupied by data of the simulated table after transmitting the data.

Abstract: An apparatus and method for determining a location and an orientation of an underground boring tool by employment of a radar-like probe and detection technique. The boring tool is provided with a device which generates a specific signature signal in response to a probe signal transmitted from above the ground. Cooperation between the probe signal transmitter at ground level and the signature signal generating device provided at the underground boring tool results in accurate detection of the boring tool location and, if desired, orientation, despite the presence of a large background signal. Precision detection of the boring tool location and orientation enables the operator to accurately locate the boring tool during operation and, if provided with a directional capacity, avoid buried obstacles such as utilities and other hazards. The signature signal produced by the boring tool may be generated either passively or actively, and may be a microwave or an acoustic signal.

The areas for the working and committed data sets are used for storage of the persistent data objects. After a persistent data object is updated in computer memory, the updated version is written to the working data set. Then, references to the working data set and the committed data set are switched, whereby the working data set becomes the committed data set and the committed data set becomes the working data set.

Abstract: A multimedia communication arrangement processes and multiplexes different types of data, including data from an adaptive data rate data source and a nonadaptive data rate data source, to substantially increase data throughput over a communication channel. The rate at which data is collected from the adaptive data rate data source varies based on the available channel bandwidth of the modem. The transmission rate is optionally adjusted in response to a detected error rate. Furthermore, the amount of filtering performed by a video camera on an image before the image is encoded by a codec can be adjusted. In addition, a data recovery terminal optionally selectively adjusts intervals at which received audio data is sampled to potentially reduce latency periods.

Abstract: A method and circuit for compression and decompression of data. For compression, successive units of input data are received in first register and second registers. The contents of the registers are used to address a lookup RAM, and the data stored in the lookup RAM is used to address a dictionary RAM. If output data from the dictionary RAM does not match output data from the first and second registers, a value from a dictionary counter is stored in the lookup RAM. If output data from the dictionary RAM matches output data from the first and second registers, data read from the lookup RAM is fed back for storage in the first register. The data from the first and second registers is provided as compressed output data. For decompression, the compressed data are used to populate another dictionary RAM, which is used to reconstruct the uncompressed data.

Abstract: A circuit arrangement utilizes a common bus for functional operations of logic circuits and for scan testing the logic circuits. In one embodiment, input/output ports and scan test ports of the logic circuits are switchably coupled to a bus. For functionally testing the logic circuits, a predetermined command transmitted over the bus causes the scan test ports to be coupled to the bus and the input/output ports to be decoupled from the bus. Test data may then be transmitted to and from the logic circuits via the bus. When testing is complete, a second predetermined command transmitted over the bus causes the scan test ports to be decoupled from the bus and the input/output ports to be coupled to the bus.
