Abstract: A system for channel sounding and initializing an equalizer using a frequency hopping sounder signal. The system identifies a frequency range for sounding a channel between a first device at a first location within a wellbore and a second device at a second location within the wellbore. Center frequencies, bandwidths, and timeframes are assigned to each of a plurality of sounding sequences, such that an entirety of the frequency range is assigned to the plurality of sounding sequences, and wherein when played in order according to the timeframe assigned to each sounding sequence in the plurality of sounding sequences, a sounding signal having a non-contiguous frequency is produced. By comparing an attenuated sounding signal based on the sounding signal to the sounding signal, the system estimates a transfer function of the channel. The system also initializes the equalizer based on the comparison.

Abstract: A method and apparatus for testing an electronic device with multiple cores is provided. The method begins when at least one scan is input for scan configuring. A signal having a predetermined number of bits is then input to a decoder. The decoder then outputs at least one assigned test channel based on the output of the decoder. A test control block then switches at least one selected scan in channel to a test control block. A hard macro scan out of channels is then input to a channel maximization device which allocates or re-allocates the channels for testing. Testing proceeds once the channels are allocated. An apparatus includes a programmable scan configuration block for adjusting the number of scan out channels to maximize testing resources and a predetermined bit register in communication with the programmable scan configuration block.

Abstract: A downlink telemetry system providing improved apparatus and methods for communicating instructions via pressure pulses from surface equipment to a downhole assembly. The apparatus comprises a surface transmitter for generating pressure pulses, a control system, and a downhole receiver for receiving and decoding pulses. In operation, a bypass valve is opened and closed to create a series of pressure pulses received and decoded by a downhole receiver. The method significantly reduces the time required for downlink communication without interrupting drilling and without interrupting uplink communications such that simultaneous, bi-directional communication is achievable if the uplink and downlink signals are sent at different frequencies. The telemetry scheme and algorithm provide an inventive method for filtering and decoding the downlink signals. The algorithm determines the time intervals between pulse peaks and decodes the intervals into an instruction.

Abstract: The invention provides a method of making tobacco rod in which method the tobacco filler material of the rod is subjected to radio frequency heating before feeding to a rod making machine. The elevated temperature increases the pliability of the tobacco filler, thus reducing its degradation in the rod making machine and enhancing the physical properties, e.g. ends stability, of the tobacco rods thus produced.
