Two sensors spaced at a known separation produce signal pulses when activated by the wheels of a taxiing aircraft. The signals are transmitted to a processor in which the wheelbase of the aircraft can readily be calculated. Since specific aircraft types have unique wheelbase dimensions and characteristics, the type of aircraft passing the sensors is determined in a processor. Also, the time, direction, and speed of the aircraft can be determined and logged by the processor.

Radioactive staining of gels is employed to identify proteins. A radioactive stain composition is formed by introducing radioactive iron isotope into ferrous bathophenanthroline sulfonate by adding crystalline ascorbic acid and acetic acid to a .sup.59 FeCl.sub.3 solution, adding aqueous BPS solution after the dissolution of the crystals, and adding methanol and acetic acid to yield the radioactive stain composition. Alternatively, the radioactive stain composition may be formed by bombarding a ...

A method for providing a node address uniquely identifies a process to be separately addressed and dispatched in a uniprocessor or multiprocessor environment. A single processor (14) identified by a unique primary node may include a single node of multiple processes (50), multiple subnodes of processes which do not replicate all of the processes in the subnode, or multiple subnodes with multiple processes replicated in each of said subnodes. Multiple processors (14), (64) and (66) may be joined ...

The present invention provides methods to identify hemochromatosis in an individual. For example, the invention provides a method of detecting reduced association of .beta..sub.2 -microglobulin with a nonclassical MHC class I heavy chain molecule or a mutation in nonclassical MHC class I heavy chain-encoding DNA which results in a reduction of .beta..sub.2 -microglobulin-heavy chain association indicating that the individual tested has or is at risk of having hemochromatosis.

An apparatus to facilitate identifying information located on a container, for example, a pharmaceutical container, includes at least one member adapted to be secured, for example, removably secured, to a container, and includes a magnifying lens.

An ECG signal is acquired in multiple channels, and sources of interference are filtered from the signals. A covariance matrix is then formed with the channels of data. The invention then employs matrix mathematics to discover a set of eigenvectors that organize the variability of data in a multi-dimensional space along new directions, orthogonal to each other and ranked in order of significance. For each eigenvector, a corresponding eigenvalue is calculated. In addition, coefficients are calcul...

A method to determine reactivity of a candidate compound with a target receptor which method does not require the physical presence of the receptor is disclosed. By providing a formula for treating data obtained from a reference set of receptors which is predictive of reactivity with the target receptor, the compound to be tested can be physically assessed with respect to the reference receptors, the formula applied, and reactivity with the actual target receptor may be predicted.

The present invention is directed to a user communication device 174, 180 for interacting with a contact center 100, comprising a user interface operable to initiate a real-time communication with a contact center 100 and an information transmission agent 184 operable, before the real-time communication is routed to a resource associated with a contact center 100, forward to the contact center 100 at least one message comprising personal information 188 of the user. The personal information 188 ...

This invention provides materials and methods to manipulate the plant genome at the level of single plant cells in culture resulting in the ability to assign metabolic functionality to plant genes involved in the production of biologically active molecules and to create a means of product discovery based on the biosynthetic capacity of plants. The materials to create an activation mutagenesis include incorporation of enhancer sequences from a plant viral promoter at random places in the plant ge...

A switch to switch protocol for network load balancing which negotiates among switches operable in accordance with the invention to assign a unique loop bit offset identifier value to each switch. Various other load balancing protocols associated with the switches then utilize the loop bit offset value as an identifier field when determining loops in the network of switches and costs associated with non-looped paths in the switches. A loop bit offset identifier requires less switch processing ov...
