Abstract: Aspects hereof relate to a translating cargo assembly for a vehicle. The translating cargo assembly may include a translation mechanism, which may be affixed to a cargo frame of the vehicle. The translating cargo assembly may also include a carrier frame that is coupled with the translation mechanism and configured to mate with cargo implements. A drive mechanism, such as a rotary actuator, may be coupled with the translation mechanism. The rotary actuator may be effective to translate the carrier frame through a range of positions including a transport position, in which the carrier frame may be adjacent to the cargo frame, and a loading position, in which the carrier frame may be proximate ground level.

Abstract: A differential signal strength direction determination systems (DSSDDS) may be programmed to provide an output that will enable an individual to determine a direction in which a source of a signal of interest is located with increased accuracy. The programming of the DSSDSS may improve accuracy by consolidating corresponding parts of a signal over time, by modifying a signal strength scale to enable an individual to better discern between the strengths of various signals and/or by providing a user-perceptible output that enables an individual to better discern between the strengths of various signals.

Abstract: Systems and methods for wirelessly sending signals through the earth between transmitting and receiving antennas are disclosed, wherein the communicating antennas are of the types that generate significant far field radiation and may interact substantially through the emission and absorption of electromagnetic radiation in addition to magnetic coupling. Frequencies are typically chosen which may be much higher than those conventionally used for through-the-earth (TTE) communications. In many situations where TTE communication is desired, the electromagnetic coupling and associated magnetic coupling produced and utilized by these certain types of antennas provide greater effective communications ranges when compared with the ranges that are obtainable with antennas interacting predominately by magnetic coupling alone.

Abstract: An electrical contact includes a crimping section for securing a wire and a flute section for receiving a pin. The flute section includes fixed engagement members and a resilient cantilever member that engages the pin within the flute section.

Abstract: An immunoassay method for the detection or quantitation of an analyte suspected of being in a solution comprising: (a) combining said specimen, a first binding component, insoluble particles, and second binding component labelled with a signal generating material in a solid phase retention and separation apparatus having a sufficient pore size such that said particles are trapped within said filter yet permitting rapid passage of fluid therethrough in such a manner that an immunological reaction occurs if analyte is present in said specimen, resulting in the formation of an immunocomplex of insolublized first binding component:analyte:second labelled binding component on or within said filter means; (b) separating bound from unbound material; and (c) determining the presence and/or amount of signal produced which is correlative with the amount of analyte present in the solution.

Abstract: The invention pertains to an improved heterogeneous enzymeimmunoassay involving the use of a reversibly soluble polymeric substance acting as the support for the antibody. In the direct method the antigen to be detected and an enzyme labeled antigen are bound by antibody which is chemically linked to the soluble polymeric substance. The polymer is rendered insoluble and removed from the test solution. After resolubilization into a solution containing substrate for the enzyme label, the assay for antigen is completed by determination of enzymatic activity. In the indirect method, the antigen to be detected and an enzyme labeled antigen are incubated with a primary antibody unattached to the polymeric substance. After addition of a second antibody which is chemically linked to the polymeric substance, the polymer is rendered insoluble and the assay is performed as in the direct method described above.

Abstract: In the determination of thyroid function in the triiodothyronine uptake and thyroxine tests, a tablet formed from a strongly basic anion exchange resin is used as a secondary binding agent to separate the bound and unbound radioactive thyroid hormone.
