Abstract: The use of a harvester head, processor head or merchandiser to deploy or place probes into a standing tree, felled stem or trunk, log, cant or the like whereby a time of flight of a stress or acoustic wave can be measured for the purpose of comparing a relationship to a threshold for the purpose of attributing a characteristic to be harvested, processed or broken down tree, stem or trunk, log, cant or the like.

Abstract: A power conversion apparatus for converting power from an alternating source to dc includes an input stage for receiving power from the alternating source, which includes an input filter, a rectifier for rectifying the alternating signal, a capacitor for storing energy from the rectified signal, and an output for outputting power from the rectifying means and the capacitor to the pulsed load. The pulsed load has at least one switched winding which receives power from the output, and wherein the capacitor is configured such that the voltage across the capacitor falls below 15% of the nominal peak rectified voltage of the source during each cycle of the alternating source. A converter of this kind provides benefits in that the current drawn from the ac supply falls within limits imposed by regulations and is simpler and cheaper than known converters of a similar power rating.

Abstract: In a method of controlling operation of a processing system, a host computer, a process tool and a component of an evacuation system, for example an abatement tool, are connected to a system bus. The abatement tool monitors signals transmitted on the system bus between the host computer and the process tool, and signals received directly from the process tool. The abatement tool uses information contained within the monitored signals to generate a signal for the process tool regarding an operating characteristic of the abatement tool. This signal is transmitted either directly or over the system bus to the process tool, which uses the generated signal to control an operating state of the process tool.

Abstract: A cathode plate and method for electro-refining or electro-winning of metal. The cathode includes a cathode blade and hanger bar. A quantity of electrically conductive material is wrapped around the hanger bar and along the cathode blade to a position, in use, proximate the level of electrolyte in the electrolytic bath. The provision of a deeper and preferably thicker coating of electrically conductive material, as compared with conventional cathode plates, reduces power consumption in the electrolytic circuit.

Abstract: The present invention relates to an immunogenic or vaccine composition to induce an immune response or protective immune response against Orbiviruses, more specifically bluetongue virus (BTV) in an animal susceptible to BTV infection. The composition may include a pharmaceutically or veterinarily acceptable vehicle or excipient, and a vector. The vector may contain heterologous nucleic acid molecule(s), expresses in vivo in the animal BTV antigen, immunogen or epitope thereof, e.g., BTV VP2; BTV VP2 and VP5; BTV VP2 and VP5 and VP3 and/or VP7. The composition can contain an adjuvant, such as carbomer. Methods for making and using such a composition, including prime-boost regimes and including as to differential diagnosis, are also contemplated.

The system includes a timing reference circuit for generating a reference clock signal, a video format detector coupled to the reference clock signal and to synchronization data derived from the incoming video signal for generating a format signal indicating the format of the incoming video signal, and a clock and timing generator circuit coupled to the format signal and the reference clock signal for generating clock and timing signals that emulate the incoming video signal, and may be locked to the incoming video signal.

Abstract: A voltage controlled band-pass filter is in a phase locked loop. The output from a phase detector is applied through a loop filter as the control voltage. The phase detector output is proportional to the difference in phase between first and second signals input to the phase detector. The first signal is fed directly from a local oscillator to the phase detector. The second signal is fed from the local oscillator to the phase detector through the voltage controlled band-pass filter.

Abstract: Methods and apparatus for scrolling database records, particularly in a client-server computing system, are disclosed. A database holds records, accessible by a server, that each include a unique identifier. A client requests the server to retrieve a set of database records. Records are retrieved from the database and stored on the server. The server determines an upper context token and a lower context token corresponding to the end records for a subset of those records. The upper and lower context tokens include a reference to the respective unique identifier. The first subset records is passed to the client for display. The client then makes a scrolling request by a previous or next subset of data, and passes the relevant upper or lower context token to the server.
