Patent EP-0438993-A2 (EP)
Inventor: PATEL ARVIND MOTIBHAI
IPC: G11B20/14
Filed: 1990-12-17
Abstract: A method is disclosed for processing, in a signal processing channel, digital values corresponding to a digitized incoming analog signal representative of coded binary data. 
     A state-dependent sequence detection algorithm includes two groups of appropriate functional expressions of digital sample values, which expressions are identical but offset one sample position from each other. During each iterating step with successive pairs of clock cycles, the value of each expression in the said two groups of expressions is precomputed from a preselected number of sample values ahead of a then current sample value; preselected ones of these expression values are compared against an appropriate threshold, which is the same for corresponding expressions of each group, to provide respective binary decision outputs corresponding to each of the two groups; and the current state value then advances to two next successive state values. 
     During precomputation, a preselected greater number of sample values ahead of the current sample is preferably used in a pipelined configuration to allow additional time for precomputing said groups of expressions.

Abstract: In a differential-detection demodulator circuit, a PSK modulated signal is compared with a locally oscillated signal to obtain a phase difference between the two signals, whereupon the phase difference is demodulated. A phase detector circuit of the digital type outputs the phase difference signal. The digital phase comparator circuit compares plural reference signals, which give predetermined delays to the locally oscillated signals having carrier frequencies, with the inputted modulated signals. Preferably, a pulse signal having a phase difference between the inputted modulated signal and the locally oscillated signal is produced, and the pulse width of this pulse signal is measured by a counter. By digitalizing the entire phase comparator, it is possible to realize demodulation with low electrical power consumption and simple circuit construction.

Abstract: This invention is based on a new model describing the drilling process of a drag bit and concerns a method of determining the drilling conditions associated with the drilling of a borehole through subterranean formations, each one corresponding to a particular lithology, the borehole being drilled with a rotary drag bit, the method comprising the steps of: measuring the weight W applied on the bit, the bit torque T, the angular rotation speed ω of the bit and the rate of penetration v of the bit to obtain sets of data (W i , T i , v i , ω i ) corresponding to different depths; calculating the specific energy E i  and the drilling strength S from the data (W i , T i , v i , ω i ); identifying at least one linear cluster of values (E i , S i ), said cluster corresponding to a particular lithology; and determining the drilling conditions from said linear cluster. The slope of the linear cluster is determined, from which the internal friction angle φ of the formation is estimated. The intrinsic specific energy ∈ of the formation and the drilling efficiency are also determined. Change of lithology, wear of the bit and bit balling can be detected.

Abstract: An optical pickup device having an optical system provided with at least a light source (11), a shaping prism (14), an diffracting element (12) and a photodetector (17). The light source projects light whose intensity distribution has an elliptical shape in its cross section orthogonal to the optical axis. The shaping prism directs the light to a recording medium after shaping the intensity distribution thereof into a circular shape. The diffracting element (12) has diffraction regions formed by at least one division line substantially parallel to a reference direction. The light reflected from the recording medium forms an elliptical bright portion on the diffracting element. The photodetector (17) is divided by a plurality of division lines, at least one of which is substantially parallel to the reference direction. The diffracting element diffracts the reflected light so as to converge it on the photodetector. Here, a hypothetical line extending from a projecting point of the light source through the center of a light-receiving face of the photodetector is also set to be parallel to the reference direction. For example, when the shaping prism is to shape the intensity distribution having the elliptical shape with respect to its minor axis direction, the optical system is arranged so that the minor axis of the bright portion is parallel to the division line of the diffracting element. Thus, it is possible to always obtain an accurate focusing control signal.

Abstract: The invention relates to a gear pump comprising a housing provided with an inlet and an outlet duct and two externally toothed gears, the bearings of which are mounted sealed against the pumped substance in the housing. The object of the present application is, by simple means, to reduce the wear and so design the gear pump that it efficiently pumps even those rubber compounds which are difficult to pump without any reduction in service life. The invention lies in the fact that the seals in the form of a delivery spiral for return of pumped substance are arranged on the ends of the gears in order to separate the pump chamber from the bearing of the gears.

Abstract: The primary dielectric resonator (RDP) is sealed in a quartz support (SQP) which holds up a secondary dielectric resonator (RDS) and keeps it at a fixed distance from the primary resonator. Tuning is achieved by a metal screw (VS) with adjustable distance from the secondary resonator. There is obtained a strong structure which minimizes the negative effects of mechanical vibrations on the resonance frequency whose adjustment is linear with the distance of the screw from the resonator. In addition the Q-factor of the cavity remains constant with the variation of the tuning frequency.

Abstract: A method and apparatus are provided for adaptively equalizing data signals in a communications receiver. An unequalized data signal is demodulated. The demodulated data signal is filtered in an adaptive equalizer (60) that initially updates adaptive filter coefficients using error signals derived from a first algorithm. A carrier lock signal is generated (62, 78) when a phase error of a filtered signal output from the adaptive equalizer reaches a threshold value. The adaptive filter coefficients are updated (74) using error signals derived from a second algorithm instead of the first algorithm in response to the carrier lock signal (72). The first algorithm is a self-recovering equalization algorithm such as the Constant Modulus Algorithm. The second algorithm can be a decision directed algorithm. Carrier phase is recovered without the use of a phase rotator or phase de-rotator, by locating the adaptive equalizer inside of the carrier recovery loop (56). The invention is particularly adapted for use in the recovery of multilevel amplitude modulated data, such as QAM data.

Abstract: A transform encoder/decoder system employs a discrete transform, adaptive transform coefficient quantization, and adaptive bit allocation to encode high-quality music including broadcast and compact disc applications at low bit rates (128 kBits per second). A fixed number of bits is allocated to low-frequency transform coefficients to reduce and/or eliminate low-frequency artifacts. Other transform coefficients are nonuniformly quantized by assigning a fixed number of bits and a variable number of bits determined adaptively based on psychoacoustic masking. A technique is described for assigning the fixed bit and adaptive bit allocations. The transmission of side information regarding adaptively allocated bits is not required.

Abstract: A memory circuit (70) is provided which has a select and a deselect mode. The memory circuit, as part of its technique for quickly accessing data, includes circuitry for generating a pulse in response to detecting an address transition (74). When the memory circuit switches from the deselect mode to select mode, there appears to be an address transition even when there is not an address transition. In order to prevent a delay associated with interpreting such a false transition as an actual transition, local clock pulse generators (88) are used which only detect high to low transitions in the chip select mode.
