Abstract: A system for leak detection and containment is disclosed. The system comprises an impermeable containment casing comprising of a solid extruded material wherein the containment casing encompasses a pipeline deployed therein. The system may further comprise a plurality of separating strips to create an annulus between the pipeline and the containment casing forming one or more flow channels, such that during a leak material leaked from the pipeline flows along a predetermined direction within the one or more flow channels. The containment casing prevents movement of the material leaked from the pipeline to an environment external to the casing. The system may further comprise a plurality of sensors to provide notification of the leak to a user device.

Abstract: A communication network and method of communication is disclosed. A server is coupled to a hybrid communication network that includes a radio frequency communication network and at least one other communication network. A communication device is configured for communication over the hybrid communication network. A mode of communication between the communication device and the server is selected. A message is then communicated over the hybrid communication network using the selected mode of communication. The communication device may be a smartphone coupled to a radio frequency transceiver and configured to drive the radio frequency transceiver.

Abstract: A ground plane apparatus (200) has a plurality of substantially planar ground plane surfaces (201) that are connected, arranged, and configured to substantially form a pyramid-shaped object. A plurality of radiating antennas (202) are then provided with at least one such antenna being mounted on each of the plurality of substantially planar ground plan surfaces such that a line of sight (205) between tips of adjacent radiating antennas is substantially occluded by at least one of the substantially planar ground plan surfaces. An electrically conductive raised surface (401) may be mounted along adjacent edges of the substantially planar ground plane surfaces. Such raised surfaces may further aid in more fully occluding the line of sight between adjacent radiating antennas. As another optional approach, additional shorted antennas (501) are also mounted along at least some of the above-noted adjacent edges to further aid in occluding this line of sight.

Abstract: The invention relates to the use of polycomb group proteins as a tumour-associated antigens. Polycomb group proteins are highly involved in body architecture development, haematopoiesis and cell cycle control. Aberrant expression of polycomb proteins has been linked with haematological malignancies, mainly lymphomas. This invention relates to the use of these polycomb group proteins as antigens for cancer immunotherapy. Immunological responses can be raised against these proteins and such responses are active against polycomb protein over-expressing tumour cells.

Abstract: A voltage-induced optical waveguide modulator is disclosed in which the inter-electrode gap is significantly reduced to a width on the order of 4 microns. The use of a dielectric layer between the electrodes and the electro-optic substrate is disclosed. A ridge of the electro-optic substrate between the electrodes is also disclosed. The dimensions of the device and operating voltage may consequently be signficantly reduced.

Abstract: A high voltage sensor using an integrated optical Mach-Zehnder device is disclosed. A capacitive divider for sensing the electric field is connected to an electrode adjacent one of the parallel waveguide sections, while a second electrode adjacent the other section is grounded. The capacitive divider may be fabricated on the same substrate as the Mach-Zehnder device. Two similar devices which can be immersed in the electric field are also disclosed. In one case the device uses a Mach-Zehnder device having waveguides of the slab type. In this variation materials having two different refractive indices, both of which are low relative to the high index slab form the superstrates of the parallel waveguide sections. In the second variation, a Mach-Zehnder device having waveguides of the diffusion type is used. Thin films of high refractive index material are deposited over the two parallel waveguide sections, with the thickness and/or refractive index of the two film sections being different.
