Abstract: A bird repellent composition containing a combination of anthraquinone and a visual cue; or anthraquinone and d-pulegone; or anthraquinone, a visual cue and d-pulegone is disclosed. The combinations have been found to produce a synergistic and unexpected effect of increased repellence to birds. One application is the area of pest control baits where the repellent composition is applied to the surface of the bait. Birds are less likely to be harmed by the toxins contained within the bait because they are repelled from the bait. A second application is for horticulture use, whereby the repellent composition is applied to the plant, fruit or ground around an orchard or vineyard thus repelling birds.

Abstract: An optical device according to the present invention is disclosed which comprises a first optical fiber and a second optical fiber disposed adjacent to each other, the first fiber being optically configured to receive incident light; a polarization dependent reflector having a preferred axis; a common lens configured to optically couple the first and second fibers to the polarization dependent reflector; and a third optical fiber coupled to the polarization dependent reflector through a second lens. The device may be characterized in that the optical device is aligned such that incident light launched into the polarization dependent reflector is provided to the second fiber at both a predetermined angle and a predetermined polarization; and such that incident light launched into the polarization dependent reflector is launched into the third fiber at a predetermined polarization.

Abstract: A data processing apparatus includes a SIMD (Single Instruction Multiple Data) array (10) of processing elements. The processing elements are operably divided into a plurality of processing blocks, the processing blocks being operable to process respective groups of data items.
