    摘要: A logging-while-drilling density sensor includes a gamma ray source and at least two NaI detectors spaced apart from the source for determining measurements indicative of the formation density. An analytic function based on a heuristic model is used to predict the measured response as a function of offset, mud density and formation density. The model may be used to provide a caliper measurement where acoustic caliper data are unreliable. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understand that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).

    摘要: Elemental analysis of an earth formation is obtained using measurements from a gamma ray logging tool. From the elemental analysis, an estimate of the mineralogy of the formation is made treating the problem as one of Linear Programming (maximizing an objective function subject to equality and/or inequality constraints).

    摘要: An in-track charging system for charging the batteries of ceiling-mounted patient lifts includes a spring-biased pin assembly integrated with a movable truck and one or more rail-mounted charging stations. The truck-mounted assembly includes multiple spring-biased brass pins having upper ends extending upward from a top surface of the truck and lower ends terminating inside the main body of the truck. A wiring cable electrically connects the lower ends of the pins with a battery to be charged. Insulated bushings surround the spring-biased pins to prevent electrical short circuiting to the body of the truck. Each rail-mounted charging station includes a pair of insulated conductive plates that are joined to the inner surface of the upper horizontal cross-piece of the rail using conductive screws and nuts. To prevent electrical short circuiting to the rail insulator bushings are placed around the screws. Wires are connected to the ends of the screws and terminate at a battery charging unit. To charge the battery, the truck is moved along the rail until it is directly beneath one of the charging stations. The position of the truck is adjusted such that the upper ends of the conductive pins rest against the heads of the screws securing the conductive plates to the rail. In that position, current passes from the charging unit, through the conductive pins and plates and to the battery.
