Filed: 2004-10-05
Granted: 2009-12-15
Abstract: A system or apparatus and method for retrieving cable from water during marine operations is provided that reduces damage to the cable from pulling forces during the retrieval. A pulling device distributes the forces and stresses all along the cable components. In one embodiment, the pulling drive comprises a pulling drum powered by a clutching system or by a hydraulic torque conversion system set to slip or stall at a selectable force value. The apparatus may use a see-saw action to maintain the forces below damaging levels. The system may be adapted for deploying cable in marine operations as well.

Abstract: The subject invention provides for a feedback loop system and method that facilitate classifying items in connection with spam prevention in server and/or client-based architectures. The invention makes uses of a machine-learning approach as applied to spam filters, and in particular, randomly samples incoming email messages so that examples of both legitimate and junk/spam mail are obtained to generate sets of training data. Users which are identified as spam-fighters are asked to vote on whether a selection of their incoming email messages is individually either legitimate mail or junk mail. A  database stores the properties for each mail and voting transaction such as user information, message properties and content summary, and polling results for each message to generate training data for machine learning systems. The machine learning systems facilitate creating improved spam filter(s) that are trained to recognize both legitimate mail and spam mail and to distinguish between them.

Abstract: Multilayered magnetic pigment flakes and foils are provided. The pigment flakes can have a stacked layer structure on opposing sides of a magnetic core, or can be formed as an encapsulant structure with encapsulating layers around the magnetic core. The magnetic core in the stacked layer structure includes a magnetic layer that is sandwiched between opposing insulator layers, which in turn are sandwiched between opposing reflector layers. Similarly, the magnetic core in the encapsulant structure includes a magnetic layer that is surrounded by an insulator layer, which in turn is surrounded by a reflector layer. The insulator layers in the pigment flakes substantially prevent corrosion of the flakes when exposed to harsh environments. Some embodiments of the pigment flakes and foils exhibit a discrete color shift at differing angles of incident light or viewing. The pigment flakes can be interspersed into liquid media such as paints or inks to produce colorant compositions for subsequent application to objects or papers. The foils can be laminated to various objects or can be formed on a carrier substrate.

Abstract: This invention is a single-piece side wheel attachment member for removably attaching an auxiliary side wheel to a bicycle. The attachment member comprises a single-piece molded structure, including an upper vertical portion and a lower substantially horizontal spindle portion connected to said vertical portion through a C-shape compliant structure for allowing said spindle portion to move vertically when subjected to force. In its natural unbiased condition, the vertical and horizontal portions of the member extend generally perpendicular to one another. The upper vertical portion includes a projection and at least one through-hole for insertion on the rear wheel axle of the bicycle. The horizontal spindle portion is rotatably engaged by the auxiliary side wheel, therefore acting as its axle. Both ends of the attachment member can angularly move relative to one another due to the C-shape compliant structure. The novelty of this invention resides in the structural simplicity of the side wheel attachment member which is, as previously stated, constructed from a single piece of material molded into a C-shape compliant structure.

Abstract: A system provides light of selectable spectral characteristic (e.g. a selectable color combination of light), for luminous applications such a signage and indicator lights (10). An optical integrating cavity (11) combines energy of different wavelengths from different sources, typically different colored LEDs. The cavity has a diffusively reflective interior surface (29) and an aperture (17) for allowing emission of combined light. Control of the intensity of emission of the sources sets the amount of each wavelength of light in the combined output and thus determines a spectral characteristic of the light output through the aperture. A deflector (25) shaped like a number, character, letter, or other symbol, may be coupled to a similarly shaped aperture. By combining several such fixtures, it is possible to spell out words and phrases, with selectable color lighting. Disclosed fixture examples use an extruded body member with appropriately located reflective surfaces to form both the cavity and deflector.
