International Classification:

G06F009/44

US Classification:

717/108000

Abstract:

A system and method for producing software code is provided. In particular, a new software design methodology is provided that is based on axiomatic design theory. In one aspect, axiomatic design theory is adapted for use in designing object-oriented software programs. This methodology overcomes the shortcomings of various software design strategies including extensive software development and debugging time and the need for extensive maintenance. Because traditional software design strategies are not heuristic and do not provide basic principles for the development of good software systems, bad design habits produce poor quality software. A design framework using axiomatic design for software overcomes many of the shortcomings of current software design techniques: high maintenance costs, limited reusability, the need for extensive debugging and testing, poor documentation, and limited extensibility of the software, all of which result in high development cost of software.

Filed:

Sep 17, 1993

Appl. No.:

8/122623

International Classification:

B05D 302
B05D 512

US Classification:

505430

Abstract:

The present invention provides a methodology for increasing the critical current density carried by high transition temperature; superconductive materials. The methodology is employed using any Noble metal to form an electrically conductive coating; and is used with any high transition temperature superconductive material conventionally known. The resulting improved superconducting material demonstrates an enhanced critical current density capability in the order of 48%; and substantially decreases the degradation of the critical current density in the presence of an applied magnetic field; and offers a range of other advantages including environmental degradation protection, an increased mechanical strength, and an improved capability for adding electrical contacts.

Assignee:

American District Telegraph Company - New York NY

International Classification:

G02B 510
G08B 1318

US Classification:

340555

Abstract:

A passive infrared detection system which exhibits a consistent optical aperture and sensitivity over different operating ranges. The system includes a mirror assembly having a plurality of spherical segments arranged in two or more ranks, each corresponding to a different operating range. Each mirror segment is disposed at its respective focal length from a detector, and is of a size and configuration to provide an intended optical aperture to achieve uniform detection sensitivity irrespective of the range of the target.

International Classification:

H02B 104
H05K 712

US Classification:

361427

Abstract:

A mounting bracket having multiple bayonet coupling elements which interengage with the bayonet coupling elements located on the body of an electrical instrument to be attached to a junction box. Additionally and in combination with the bayonet coupling elements, on the bracket and instrument body respectively, are included a pawl and ratchet arrangement for providing fine rotational adjustment while a toothed spring finger attached to the bracket engages a notched annular wall on the instrument body so as to latch and further secure the bracket to the body. It is anticipated that the mounting bracket will have to be attached to any one of several types of junction box thereby necessitating a multidirectional coupling arrangement for properly attaching the subject instrument to the particular junction box encountered.

Eliza Corporation - Beverly MA

International Classification:

G10L 500

US Classification:

381 43

Abstract:

A phoneme estimator in a speech-recognition system includes energy detect circuitry for detecting the segments of a speech signal that should be analyzed for phoneme content. Speech-element processors then process the speech signal segments, calculating nonlinear (powers and products) representations of the segments. The nonlinear representation data is applied to speech-element modeling circuitry which reduces the data through speech element specific modeling. The reduced data are then subjected to further nonlinear processing. The results of the further nonlinear processing are again applied to speech-element modeling circuitry, producing phoneme isotype estimates. The phoneme isotype estimates are rearranged and consolidated, that is, the estimates are uniformly labeled and duplicate estimates are consolidated, forming estimates of words or phrases containing minimal numbers of phonemes. The estimates may then be compared with stored words or phrases to determine what was spoken.
