  • Publication number: 20100043104
    Abstract: The present invention provides a process for generation of a transformed plant capable of emitting fluorescence by introducing a gene encoding a non-plant-derived fluorescent protein into a plant such that the fluorescent protein is recombinantly expressed in the active form of its mature protein in the leaf or petal of the plant, and also provides a transformed garden plant capable of emitting fluorescence that is generated by using the process. For example, cDNA encoding the full-length amino acid sequence of a Chiridius poppei-derived fluorescent protein CpYGFP or its H52F modified protein CpYGFP H52F is inserted into a T-DNA-based expression vector system, which is in turn introduced into the chromosomal DNA of a plant. As a result, the transformed plant thus generated can exhibit fluorescence attributed to these fluorescent proteins and exhibit no substantial difference in the other phenotypes from wild-type one of the plant.

  • Publication number: 20100042803
    Abstract: A state transition management device includes a memory that stores subsequent state number candidates for a current state number and a selection circuit that selects a subsequent state number from among the subsequent state number candidates that have been read out from the memory. For the state number having the subsequent state number candidates that are branch destinations of the current state number and are small in number, the memory stores the subsequent state number candidates for a plurality of current state numbers at one address in the memory that can be concurrently read out. The selection circuit selects the subsequent state number based on an event identification code (109, 110) and a current state number.

  • Publication number: 20100042876
    Abstract: A method and system for packet transmission in a hybrid automatic repeat request (ARQ) system. A modulation and a block length for a transmission are determined based on the average mutual information per bit. The average mutual information per bit is computed based on a current channel signal-to-noise ratio and a plurality of previous transmissions, each being transmitted with a respective coded block length, modulation form, and signal-to-noise ratio. A block error rate is computed for the potential block lengths and modulations based on the average mutual information per bit, and a throughput of the current transmission is determined based on the block error rate. The modulation form and the block length of the transmission are determined based on an analysis of the throughput. If the receiver cannot decode the current transmission, the transmitter repeats the computation to determine the modulation and the block length for retransmission.

  • Patent number: 7664306
    Abstract: In a visual inspection method and apparatus, a picture processing unit converts an original picture, obtained by taking a photograph of a BGA illuminated by a ring illuminator from above, by using a camera, and labels a binary picture obtained by this binary conversion. Then, it forms a circumscribing rectangle circumscribing an outer circumference of a labeling picture obtained by the labeling, and inverts a labeling picture within the formed rectangle, and removes a portion of a region formed by the outer circumference and the circumscribing rectangle in a picture obtained by the inversion, and then generates an inspection picture by adding a picture obtained by the removal to the labeling picture, and accordingly judges a pass or rejection of the inspection target sample based on the generated inspection picture. Thus, the inspection can be carried out at a high accuracy irrespectively of a low cost.

  • Patent number: 7664524
    Abstract: The invention provides a mobile communication terminal that allows the time for recognizing the scrambling code to be shortened. The mobile communication terminal predicts the scrambling code to be searched at the next time by collating the previous result of GPS information process and the stored content of a position information database in a control part, if establishment of slot synchronization is completed employing a slot synchronization part. The control part acquires the information required for inverse spreading of the predicted scrambling code from a memory, and generates a code for inverse spreading. A predicted scrambling code recognition part inputs the code for inverse spreading shifted in a unit of slot from the control part, and attempts inverse spreading.
