Abstract: A method and system for blending biogas with conventional fuel in which the fuel blend is automatically adjusted for lower biogas flows and methane concentrations by introducing higher concentrations of conventional fuels. The system is able to automatically adjust the fuel blend, thereby eliminating the requirement for manual intervention, and producing a variable blended biogas that can be utilized within existing natural-gas fired combustion units such as boilers, furnaces, heaters, etc., as well as enabling automatic adjustment and operation, maximum usage of biogas, and integration with combustion unit controls. Using all available biogas to provide energy also minimizes the need for flaring unused biogas.

Abstract: An improved technique for acoustic sensing involves, in one embodiment, launching into a medium, a plurality of groups of pulse-modulated electromagnetic-waves. The frequency of electromagnetic waves in a pulse within a group differs from the frequency of the electromagnetic waves in another pulse within the group. The energy scattered by the medium is detected and, in one embodiment, the beat signal may be used to determine a characteristic of the environment of the medium. For example, if the medium is a buried optical fiber into which light pulses have been launched in accordance with the invention, the presence of acoustic waves within the region of the buried fiber can be detected.

Abstract: Systems and methods are described to allow arbitrary 3D data to be rendered to a 2D viewport on a device with limited processing capabilities. 3D vertex data is received comprising vertices and connections conforming to coordinate processing constraints. A position and orientation of a camera in world co-ordinates is received to render the 3D vertex data from. A processing zone of the plurality of processing zones the position of the camera is in is determined. The vertices of the 3D vertex data assigned to the determined processing zone are transformed based on the position and orientation of the camera for rendering to the viewport.

Abstract: There is provided a distributed sensor, comprising a length of optic fibre; an interrogator unit having a detector arranged to detect light from the optic fibre, wherein the interrogator is arranged to provide distributed sensing on the optic fibre and wherein an optical path is defined between the optic fibre and the interrogator detector; a sampler coupled to the optic fibre and arranged to obtain a sample of light from the optical path of the optic fibre; a threshold detector arranged to detect the intensity of the sampled light and determine whether the intensity of the sampled light is above a threshold value; and an optical attenuator provided in the optical path and arranged to attenuate light propagating along the optical path when the intensity of the sampled light is above the threshold value. By attenuating light in the optical path if it is above a threshold value, the sensitive detector in the interrogator unit can be protected.
