Patent CA-2264060-C (CA)
Title: A high performance self modifying on-the-fly alterable logic fpga
Inventor: CHATTER MUKESH
IPC: G06F15/78
Filed: 1997-08-12
Granted: 2008-01-08
Abstract: A technique for configuring arrays of programmable logic cells, including those associated with FPGA devices, through a novel DRAM-based configuration control structure that enables not only "on-the-fly"  alterable chip and similar device reconfigurations, but, where desired, self-modifying reconfigurations for differing functionalities of the devices, eliminating current serious reconfigurability limitations and related problems, while providing significantly enhanced system performance at low cost. A large amount of memory is available internal to the FPGA and is accessed with a small number of pins such that the reconfiguration time is, for example, four orders of magnitude faster than the traditional approaches and at notably low cost.

Title: Method and apparatus for the detection of holes and plugged spots
Inventor: GILBERT P DANIEL
IPC: D21G9/00
Filed: 1997-09-17
Granted: 2003-07-22
Abstract: A method and an apparatus for detecting plugged sites and holes and for measuring of the water permeability properties of pervious machine fabrics is disclosed. Plugged sites in a permeable fabric are detected by sensing water pressure pulses occurring in the nozzle at the moment when a stream of water flowing through the nozzle contacts a plugged site on a fast running fabric.  The apparatus can be used on-line to simultaneously detect plugged sites and holes on a moving pervious fabric while monitoring its water permeability properties.

Title: Chaff cutter for comminuting haulm behind the grain-separator devices of a combine harvester
Inventor: JAKOBI WILHELM
IPC: A01D41/12
Filed: 1996-09-10
Granted: 2007-06-26
Abstract: The subject matter of the invention is a straw-cutting machine which is disposed behind the grain separating devices of a combine harvester and whose separating means cut up the stalks falling down from the straw walkers into short piece s. In this process, thanks to an innovative, special disposition of the generally conventional deflector which, under the straw walkers, deflects the stalks falling down from these to the cutter tray at the inlet into the cutter, the receiving of the stalks by the cutting drum is made more secure and, on the other hand, thanks to an innovative, special design of the distribution hood following the cutter, the ejection and the distribution of the chopped up stalks over the field soil is essentially improved over existing designs.

Abstract: When a steering angle speed (V.theta.), a rate of change of a steering angle with respect to time is not higher than a predetermined stop threshold level (Vb) (YES at S10) with a motor current value (Im) within a motor stop range (.DELTA.I), which is determined on the basis of a no-load current value, for a predetermined period of time (YES's at S12 and S13), a motor is stopped (S14). Since the no-load current value is a value recorded when the steering torque is zero, the motor stop range corresponds to a range in which steering assistance is not required.  Namely, when both the steering angle speed (V.theta.) and steering torque are small, the steering assistance is regarded as unnecessary, and the motor is stopped.

Abstract: Replica correlation processing, and associated representative signal-data reduction and reconstruction techniques, are used to detect signals of interest and obtain robust measures of received-signal parameters, such as time differences of signal arrival and directional angles of arrival, that can be used to estimate the location of a cellularized-communications signal source. The new use in the present invention of signal-correlation processing for locating communications tranmitters. This enables accurate and efficient extraction of parameters for a particular signal even in a frequency band that contains multiple received transmissions, such as occurs with code-division-multiple-access (CDMA) communications. Correlation processing as disclosed herein further enables extended processing integration times to facilitate the effective detection of desired communications-signal effects and replication measurement of their location-related parameters, even for the communications signals modulated to convey voice conversations or those weakened through propagation effects. Using prior, constructed signal replicas in the correlation processing enables elimination of the inter-site communications of the signal representations that support the correlation analyses. Reduced-date representations of the modulated signals for voiced conversation, or for the variable components of data communications, are used to significantly reduce the inter-site communications that support the correlation analyses.

Title: Method and apparatus for fine frequency synchronization in multi-carrier demodulation systems

Granted: 2003-08-12
Abstract: A method and an apparatus relate to a fine frequency syn- chronization compensating for a carrier frequency deviation from an oscillator frequency in a multi-carrier demodulation system of the type capable of carrying out a differential phase decoding of multi-carrier modulated signals, the sig- nals comprising a plurality of symbols, each symbol being defined by phase differences between simultaneous carriers having different frequencies. A phase difference between phases of the same carrier in different symbols is deter- mined. Thereafter, a frequency offset is determined by eliminating phase shift uncertainties related to the trans- mitted information from the phase difference making use of a  M-PSK decision device. Finally, a feedback correction of the carrier frequency deviation is performed based on the deter- mined frequency offset. Alternatively, an averaged frequency offset can be determined by averaging determined frequency offsets of a plurality of carriers. Then, the feedback correction of the frequency deviation is performed based on the averaged frequency offset.

Abstract: Over-sampled timing signal jitter tolerance is improved in a q-times over-sampled architecture by phase-sampling the timing signal to produce a plurality of input phase samples ~in, where ~in .epsilon. {~1,~2,...,~q). An output phase value ~out = ~in is initialized for each input sample ~in. A difference vector d i is derived for each input sample ~in, where d i = F j(n,k). F denotes a vector operation, n is the number of input samples, k is a pre-defined threshold value, and j represents a filter order value. A predefined scaling coefficient ai is applied to each difference vector d i to produce a corresponding set of scaled difference vectors a i d i. The scaled difference vectors are summed:   The output value ~out is incremented by 1 if d j > k; decremented by 1 if d j < -k; and maintained unchanged if -k <= d j <= k. Finally, the output value ~out is selected to represent the input sample ~in.
