  • Publication number: 20140105344
    Abstract: A method for radio frequency (RF) pulse synchronization in a super regenerative receiver (SRR), includes receiving an input signal including an asymmetric preamble, and estimating a phase difference between the input signal and a quench signal based on the asymmetric preamble. The method further includes compensating for the phase difference.

  • Patent number: 8402401
    Abstract: One embodiment provides a method for protecting an integrated circuit chip design. The method can include storing in memory a circuit description of an integrated circuit core comprising a set of nodes and selecting a plurality of modification nodes from the set of nodes. A sequential structure can be inserted into the circuit description to provide a modified circuit description, the sequential structure utilizing the plurality of modification nodes as inputs. The modified circuit description can be stored in memory.

  • Publication number: 20120159668
    Abstract: Polynucleotides isolated from chickpea are disclosed herein. The disclosed polynucleotides of the present invention provide genotype-dependent spatial information on the presence and relative abundance of each gene. The transcriptomic analysis of the polynucleotides revealed (649) non-cannonical genes besides many unexpected candidates with known biochemical functions, which have never been associated with pathostress-responsive transcriptome. The polynucleotides disclosed in the present invention can be used as a molecular tool for isolation of novel genes from plants that can be used for plant improvement. Further, the polynucleotide responsible for improving immunity against fungal pathogen in plants is disclosed herein. The present invention also provides a method of improving immunity against fungal pathogen in plants. Transgenic plants exhibiting improved immunity against fungal pathogen are also provided in the present invention.

  • Patent number: 8163977
    Abstract: The present invention relates to environmental stress responsive protein ferritin (CaFer1) of chickpea. The invention discloses identification, isolation and cloning of ECM-localized ferritin (CaFer1) of chickpea and its multifunctional role in nutrient uptake, storage and stress tolerance. Comparative proteomic analysis of the chickpea extra-cellular (ECM) was performed to identify novel components of dehydration stress signaling. In addition, the present invention relates a method for producing environmental stress tolerant transgenic plants over-expressing the said CaFer1 gene. The present invention further provides dehydration stress tolerant transgenic plants overexpressing dehydration-responsive extra cellular matrix (ECM) protein ferritin (CaFer1).

  • Patent number: 7673224
    Abstract: An apparatus and method of reducing power dissipation in a register exchange implementation of a Viterbi decoder used in a digital receiver or mass-storage system without degrading the bit error rate of the decoder, by selectively inhibiting data samples in the Viterbi decoder's register memory from being shifted if the data samples have converged to a single value. FIFO memories keep track of what data samples have converged, the order of the samples, and the converged data value, thereby keeping the decoded data in the FIFO synchronized with data continuing to be shifted through the register memory.
