Title: Genomic ppo clones
Inventor: ROBINSON SIMON PIERS
IPC: C12N15/53
Filed: 1997-01-24
Granted: 2009-09-22
Abstract: The present invention relates to the isolation of genes encoding polyphenol oxidase (PPO) from plants. In a first aspect of the present invention there is provided a method for preparing nucleic acid encoding PPO , fragments and derivatives thereof, which method includes providing a sample of plant tissue, a first primer in sense orientation havi ng a sequence corresponding to a conserved region of a PPO gene, a second primer in antisense orientation having a sequence corresponding to a conserved region of a PPO gene; isolating genomic DNA from said plant tissue; and amplifying the genomic DNA using the first and second primers. Surprisingly, the applicant has found that PPO genes in plants lack introns and, therefore, fragments of PPO genes may be amplified directly from genomic DNA of a range of plants. The lack of introns means that the size of the fragments can be predicted an d bands of the appropriate size can be selected for cloning.

Title: Echo controller with compensation for variable delay networks
Inventor: MCCLENNON R SCOTT
IPC: H04M3/00
Filed: 1999-09-09
Granted: 2007-06-05
Abstract: The present invention provides a method of and system for controlling and effectively reducing the echo introduced in telephone connections over variable delay networks such as LAN/WAN networks. The invention includes estimation of the round-trip user-to-user delay in the telephone connection. This estimation can be made in a number of different ways, including using timestamps in existing data packets according to a Real-Time Protocol (RTP) or a Real-Time Control Protocol (RTCP) and by sending timestamps in data packets according to an Internet Control Message Protocol (ICMP). The invention further includes determination of an echo control target for the telephone connection based upon the estimated user-to-user delay. This target represents the total amount of echo control required to limit the probability of objectionable echo to less than a predetermined threshold. The amount of echo control required increases as the length of the estimated user-to-user delay increases. The invention further includes determination of the minimum amount of signal-dependent loss required to supplement the acoustic echo cancellation in order to reach the determined echo control target. Then, in the invention, the determined amount of signal- dependent loss is applied to the telephone connection to effectively reduce echo based upon the estimated user-to-user delay.

Abstract: Information is processed to produce a plurality of information symbols. The plurality of information symbols are encoded according to a concatenation of an error correction code and a nonorthogonal modulatio n code to produce a modulated communications signal. The modulated communications signal is communicated over a communication medium, and communications signal processing means process the communicated modulated communications signal to produce information. Preferably, the information symbols are encoded according to an error correction code, preferably a convolutional code, to produce a plurality of coded symbols. The plurality of coded symbols are preferably interleaved to produce a plurality of interleaved coded symbols. The interleaved coded symbols are then modulated according to a nonorthogonal code to produce the modulated communications signal. Preferably, the coded symbols are modulated according to a proper subset of one of a Nordstrom-Robinson code, a Reed-Muller code, or a Kerdock code, the proper subset being operable to produce a modulated communications signal from a signal set such that the communications signal noncoherently demodulates to produce a unique output for each signal in the signal set, and the communications signal processing means includes noncoherent demodulatingmeans for noncoherently demodulating the communicated modulated communications signa l.

Abstract: An ASK modulator can be operated with only a positive-voltage power source. A source-voltage switching circuit that applies a positive voltage to the source of an FET when a data signal is at an L level in relation to the source of the FET is connected to the source of the FET which has a negative pinch-off voltage. Since the L level of the data signal can be set to 0 V, the ASK modulator can be configured only with the positive-voltage power source.      This allows miniaturization and cost reduction to be implemented.

Abstract: A method and apparatus facilitate the creation and maintenance of web pages which include reusable, upgradeable components. The apparatus provides a simple client object which can identify and contain properties for reusable components from a library.  The client object does not itself need to be upgraded when components are upgraded and therefore it is not necessary to re-specify all of the properties for a component when a component is upgraded. An upgrade tool reads the properties of instances of the client object which is present in the source for a web publishing software, identifies an upgraded version of a component identified by the client object, reads the properties specified for the component by the client object and reconfigures the instance of the client object to identify the upgraded component and to specify corresponding properties for the upgraded component. Use of the invention facilitates rapid upgrading of web pages.

Title: Leptin-mediated gene-induction
Inventor: TAVERNIER JAN
IPC: C12N15/09
Filed: 1999-07-27
Granted: 2010-01-19
Abstract: Using the PC12 cell line as a model system a series of transcripts induced through activation of the leptin receptor or gp130 was identified. Based on kinetic studies on undifferentiated PC12 cells, two distinct gene-sets could be discerned: STAT-3, SOCS-3, Metallothionein-II, the serine/threonine kinase Fnk and the rat homologue of MRF-1 which are immediate early response genes, and Pancreatitis Associated Protein I, Squalene Epoxidase, Uridinediphosphate Glucuronyl Transferase and Annexin VIII, which are late induced target genes. In the latter case only, a strong co-stimulation with the adenylate cyclase activator forskolin was observed. Two additional transcripts encoding Leptin Induced Protein I(LIP-I) and Leptin Induced Protein II (LIP-II) were also identified. LIP-II is a rat orthologue of the human Down Syndrome Cell Adhesion Molecule (DS-CAM). In both cases, no forskolin co-stimulatory effect was observed. On PC12 cells differentiated to a neural phenotype by combined .beta.-NGF and forskolin treatment, Pancreatitis Associated Protein III, Peripherin and Mx2 protein were further identified as being regulated by leptin. Finally, from an RDA experiment using mRNA from either hyper-IL-6- or leptin-induced PC12 cells, the Reg gene, another member of the Pancreatit is Associated Proteinfamily, and HIP-1 were identified as selectively up-regulated by H-1L-6. STAT-3 and SOCS-3 have been recognized i n leptin signalling in vivo before. In this invention it is also demonstrated that leptin modulates the in vivo expression of the MT-II, Fnk and Pancreatitis Associated Protein I genes.

Title: Incremental actions relating to notify and target models
Inventor: DALY RUTH S
IPC: G06F19/00
Filed: 2001-03-12
Granted: 2004-11-09
Abstract: Embodiments of the invention provide for an action to be performed on a target model based on changes in the notify model. The difference between this, and the previous examples, is that in the previous examples, the actions are performed against the notify model, not the target model. When an action needs to be performed based on a change in the target model, the previous examples of behavior are inadequate. Because the target model does not notify that it has been changed, a correlation between the notify model and target model will be used to determine what has changed in the target model. Given that the notify model and the target model are representations of the same data, if the notify model sends an event notification (which indicates that a change has occurred in the notify model), it can be deduced that the corresponding item in the target model has been changed, too. Based on the changes made in the notify model, and using a mapping of the linkages associating objects in the notify model to objects in the target model, the objects in the target model affected by the changes in the notify model are identified. The action (e.g., a validation check) is performed only on the changed parts of the target model.
