Title: Device for receiving digital signals and device for transmitting digital signals
Inventor: SPREITZ GERALD
IPC: H04H20/00
Filed: 2000-07-20
Abstract: A device for receiving digital signals and a device for transmitting digital signals is proposed; in order to transmit the signals, these serve, to interleave the symbols that are contained in the digital signals, and combine the symbols to form memory words, and subject the memory words to a cyclical delay and, on reception, to combine the received signals that have the same delay to form memory words and subject them to a further delay so that all the symbols have the same overall delay. The devices comprise an intermediate memory that is used for presorting and registers that are used, on the one hand, for combining symbols to form memory words and, on the other hand, to reseparate the memory words into symbols. The devices for receiving and transmitting digital signals are each connected to a data bus to which the memory is also connected. The present inventions entails the advantage that the data bus is subjected to a load that is so low that the data bus can be made available to other components.

Title: Self-calibrated ultrasonic method of in-situ measurement of borehole fluid acoustic properties
Inventor: MANDAL BATAKRISHNA
IPC: G01N29/30
Filed: 2002-08-08
Abstract: The present invention finds the acoustic impedance of the drilling fluid using reflections from a precise metal disk, and therefrom the density of the drilling fluid.  Because the reverberation characteristics of an acoustic wave depend in part on the acoustic wave shape, the first reflection from the metal disk may be used to calibrate the measurement.  A method for determining a borehole fluid property is disclosed that includes (l) generating an acoustic signal within a borehole fluid, (ii) receiving reflections of the acoustic signal from the fluid, and (iii) analyzing a reverberation portion of the acoustic signal to determine the property. The analyzing of the reverberation portion may include obtaining a theoretical reverberation signal and relating the measured reverberation signal with the theoretical reverberation signal to determine the borehole fluid property.

Abstract: A spectrophotometer includes an optical measurement head (100), a spectrometer (200) and a control electronic (300). The measurement head is equipped with a multi-channel illumination arrangement which includes exclusively light emitting diodes (13) as spectrally continuous light source. Each illumination channel (11) includes a light emitting diode (13), whereby each light emitting diode is separately controllable. The measurement head includes further a preferably telecentrically constructed collecting channel (12) for the capturing of the measurement light remitted or emitted by the sample and for the coupling of the same into the spectrometer (200). The illumination channels (11) are positioned in a circle around the optical axis of the measurement head (100) and illuminate the sample under different angles of incidence. The measurement head includes at least one white light emitting diode and additionally light emitting diodes with different imaging spectra as well as UV light emitting diodes. In combination with the control electronic, an illumination with electronically adjustable spectral characteristics is hereby realized. For a contact-free measurement, means for the determination of the measurement distance and a distance dependent numerical correction of the measurement data is provided. The spectrophotometer can be constructed very compact and allows a versatile use on all input and output media involved in a color management system. The spectrophotometer is especially also usable as a built-in device or measurement sensor in automated color measurement systems or directly in color printing systems. The spectrophotometer is especially suited for the measurement of both color as well as material and color reproduction properties and effect color layers, and permits the formation of device profiles of the most different type from the measurement results, to enable in such a way an exact visualization of the color reproduction properties of a manufacturing process.

Title: System and method for fast code phase and carrier frequency acquisition in gps receiver
Inventor: SULLIVAN MARK C
IPC: G01S1/00
Filed: 2001-09-10
Abstract: A GPS receiver (301) acquires carrier frequency and Gold code phase using short segments of a received GPS signal. In one embodiment, a 1-ms segment of the GPS signal is transformed to the frequency domain. This is multiplied (404) by a frequency representation of the Gol code (402). The resulting product is converted to the time domain, and a peak (406a-d) is detected. The location of the peak (406a-d) corresponds to the code phase. If no peak(406a-d) is located, the carrier frequency is changed. Full- and half-bin steps in carrier frequency are considered. Processing gain is achieved by using longer segments of the input signal, for example 4 or 16 ms and integrating 1-ms segments. Considerations are provided for compensating for the effects of a transition, should it occur in the short segment of the GPS signal being processed. Integrations can be performed using non-coherent and coherent techniques. Adjustments are made for non-integral millisecond segment lengths.
