Abstract: A method includes receiving data characterizing a configuration of an asset configured within an oil and gas production environment. The data can include attribute-value pairs identifying attributes of the configuration of the asset and values of the attributes. The attribute-value pairs can correspond to a hierarchical structure of the asset and sub-components of the asset. The method can include determining a representation of the asset. The representation can be provided in a provided in a language-independent format suitable for use with data interchange application programming interfaces. The method can include determining an asset model of the asset. The asset model can include a digital representation characterize the hierarchical structure of the asset and sub-components of the asset. The asset model can include computer-readable, executable content associated with the attribute-value pairs. The method can include providing asset model.

Abstract: A motorcycle trailer converts between a single mode, for towing one motorcycle, and a dual mode for towing two motorcycles. In the single mode, a longitudinal frame includes a front member, a center member and a rear member which assemble to provide an elongate, narrow platform with a tire channel for receiving the front and rear wheels of a motorcycle. Left and right wheel assemblies each include a wheel with a tire, an axle and an axle extension that slides into an axle sleeve fixed to the underside of the longitudinal frame. A straight coupler is fitted to the front member for hitching the assembled trailer to a tow vehicle. In the dual mode, two assembled longitudinal frames, each having the front member, center member and rear member, are positioned in parallel spaced relation and an axle extension is connected between the axle sleeves.

Abstract: The present invention relates to carrot lines having roots containing increased levels of lycopene, as well as containers of such carrots. The present invention also relates to parts of carrot plants from lines having roots with increased lycopene content, including seeds capable of growing carrot plants with increased root lycopene content. The invention also provides seed and plants of the carrot lines designated RN 71-4904C, RF 71-4911A, RF 71-4912A, RIF 71-4966C, RIF 71-4967B, or RIF 71-4968B. The invention thus relates to the plants, seeds and tissue cultures of carrot line RN 71-4904C, RF 71-4911A, RF 71-4912A, RIF 71-4966C, RIF 71-4967B, or RIF 71-4968B, and to methods for producing a carrot plant produced by crossing a plant of carrot line RN 71-4904C, RF 71-4911A, RF 71-4912A, RIF 71-4966C, RIF 71-4967B, or RIF 71-4968B with itself or with another carrot plant, such as a plant of another line. The invention further relates to seeds and plants produced by such crossing.

Abstract: A discrete multitone stacked-carrier spread spectrum communication method is based on frequency domain spreading including multiplication of a baseband signal by a set of superimposed, or stacked, complex sinusoid carrier waves. In a preferred embodiment, the spreading involves energizing the bins of a large Fast Fourier transform (FFT). This provides a considerable savings in computational complexity for moderate output FFT sizes. Point-to-multipoint and multipoint-to-multipoint (nodeless) network topologies are possible. A code-nulling method is included for interference cancellation and enhanced signal separation by exploiting the spectral diversity of the various sources. The basic method may be extended to include multielement antenna array nulling methods for interference cancellation and enhanced signal separation using spatial separation. Such methods permit directive and retrodirective transmission systems that adapt or can be adapted to the radio environment.

Abstract: A trailer is provided with extendable and retractable left and right axle portions slidably supported within an axle sleeve, and hinged side panels to facilitate conversion of the trailer between a full size mode and a compact mode. In the full size mode, the left and right axle portions are extended and locked to position left and right tires at maximum separation, and the side deck panels are lowered to be generally co-planer with a center deck panel arrangement for towing behind a conventional vehicle. A front panel hinges between a raised position and a lowered position. In the compact mode, the left and right axle portions slide inwardly, within the sleeve, and lock into place to position the left and right tires closer together. The side panels and front panel swing upwardly to be generally perpendicular to the center deck panel assembly, forming a box. Left and right ramps are cooperatively structured to provide a cover and a rear wall to fully enclose the formed box.

Abstract: A hitch guide is a device to aid the driver of a pickup truck in mounting a gooseneck trailer hitch onto the hitch ball mounted in the bed of a pickup truck. the present device has a strap mounted between tow end pieces which in turn mount on the side rails of a pickup truck bed to that the end pieces may be moved along the length of the pickup truck bed for adjustment purposes. A marker, mounted on the strap, may be adjusted laterally between the two pickup bed rails. When the strap and marker are properly adjusted, the pickup truck when backed up to the mounting pole of a gooseneck trailer so that the marker is just touching the mounting pole will be oriented so that the mounting pole and gooseneck trailer hitch are aligned directly over the hitch ball in the pickup truck bed.

Abstract: A step holding member has a first end which is insertable into a receiver-type trailer hitch and a second end which is adapted for holding a step member for stepping onto the tailgate of a pickup truck. In another embodiment of the invention the step holding member telescopes in and out towards a side of a pickup truck allowing for easy storage when telescoped in. In a third embodiment the step holding member folds inwards from the pickup towards the trailer hitch for storage. A fourth embodiment is adapted for mounting directly onto a trailer hitch drawbar so that the hitch may be used for towing with the step in place for use.
