Abstract: A system for rental fraud detection comprises an input interface, a feature vector extractor, a model builder, and a predictor. The input interface is to receive a set of training data, wherein the set of training data comprises a set of rental fraud indications and to receive a set of prediction data. The feature vector extractor is to extract a first training set of feature vectors from the set of training data and to extract a first test feature vector from the set of prediction data. The model builder is to build a first model using the first training set of feature vectors and the rental fraud indications. The predictor is to predict whether the first test feature vector corresponds to fraudulent data using the first model.

Abstract: We present optical systems suitable for focusing two substantially collimated beams or sheets of light propagating in different directions onto a common focal point. In some embodiments the optical systems comprise separate focusing elements for each beam or sheet of light, while in other embodiments the optical systems comprise a focusing element and a redirection element. The optical systems have particular application in the receive optics of infrared touch screens, where they enable the detection of additional light paths that assist in the determination of two or more simultaneous touch events.

Abstract: The invention describes various optical waveguide layouts with reduced substrate area, with particular application to reducing bezel width in optical touch systems. In certain preferred embodiments the optical waveguide layouts include a plurality of waveguide crossings.

Abstract: An apparatus and method for transmitting, collimating and redirecting light from a point-like source to produce a collimated optical signal in a substantially planar form are provided. In one embodiment the apparatus is manufactured as a unitary transmissive body comprising a collimation element and a redirection element, and optionally a transmissive element. In another embodiment the apparatus is assembled from one or more components. The apparatus and method are useful for providing sensing light for an optical touch input device.

Abstract: A data input apparatus having at least one transmit element coupled to a source of light of a predetermined wavelength, at least one light receive element and a detection device to detect interruption of beams of the light of said predetermined wavelength extending from said transmit element to said receive element wherein at least one of said transmit element and said receive element comprises at least one waveguide having a light transmitting core and a non-core portion and one or more discontinuance means adapted to reduce transmission of stray light within the non-core portion. The discontinuance is adapted to scatter, absorb, divert or block stray light and can be applied to one or more of the upper cladding, lower cladding, substrate or common base.
