The equation operating system is an improved data and command entry format together with a compatible operation system for use with electronic data processing apparatuses, most particularly with scientific calculators which provide an alphanumeric display of entered equations. This invention also includes a unary operation implementation technique, whereby the operand may be entered either before or after the unary operation.

The equation operating system is an improved data and command entry format together with a compatible operation system for use with electronic data processing apparatuses, most particularly with scientific calculators which provide an alphanumeric display of entered equations. This invention provides an implied multiplication having differing hierarchical ranks when one of a member of a predetermined prefix set entry is followed by one of two differing suffix set entries. Each of these implied multiplications have a differing hierarchical rank than that of explicit multiplication.

The equation operating system is an improved data and command entry format together with a compatible operation system for use with electronic data processing apparatuses, most particularly with scientific calculators which provide an alphanumeric display of entered equations. This invention provides a different set of commands and displayed characters for performing exponentiation. An up arrow together with a down arrow serve to define the expression of the exponent. The numeric data stored in a numeric display register upon implementation of the exponentiation is raised to the power of the expression between the up arrow and the down arrow. This invention also includes an integral power exponentiation command which enables easy entry of single digit positive integral exponents, thereby eliminating the need for a completing command.

A gas turbine engine augmentor includes an augmentor outer casing 502 and an annular augmentor liner 504 disposed radially within and radially separated from the augmentor outer casing 502 to form a generally annular augmentor liner cooling flow path 500 between the augmentor casing and the annular augmentor liner, and an augmentor flow splitter duct 506 disposed at the upstream end of the augmentor liner and radially between the augmentor outer casing 502 and the annular augmentor liner 504 and defining a splitter flow path 520 between the annular augmentor liner 504 and the annular augmentor flow splitter duct 506. A method of operating a gas turbofan engine including an augmentor includes directing a portion of fan bypass air into a generally annular augmentor liner cooling flow path 500 between an augmentor outer casing 502 and an annular augmentor liner 504, directing a portion of the air in the augmentor liner cooling flow path 500 into a splitter flow path 520 disposed radially outside the augmentor liner 504 and maintaining positive backflow pressure margin between air flow within the splitter flow path and the augmentor liner cooling flow path 500.

The present invention relates to methods for identifying cucumber lines having increased resistance to Downy Mildew, and identification of genetic markers linked to gene(s) conditioning such increased disease resistance. The present invention also relates to methods of breeding cucumber plants from lines having increased Downy Mildew resistance by marker-assisted selection, compositions including nucleic acid probes or primers which are useful for such marker assisted selection, and plants and plant parts produced by such methods.

Flexible power converter and simplified process controller capable of being configured for a variety of applications with minimal effort. The power converter has a plurality of filtered half-bridges that can be configured for multiple topologies. The process controller can be adjusted through a timing parameter to process the configured feedback signal. External settings or serial port configuration enable stand-alone or processor-based operation. The invention may be quickly and easily applied as a versatile power supply, motor driver, thermal regulator, or controller for Lighting and flow applications. The flexible power converter and simplified process controller reduces development time and cost, reduces parts count and cost, and improves performance and reliability of power and control systems.
