Abstract:

An electrolytic reactor and related methods are provided for supplementing the air-intake of an internal combustion engine with hydrogen. In one embodiment, the reactor has a core defined by a plurality of whole metal plates separated by peripheral gaskets; an inlet for providing an electrolyte to the core; a gas and effluent outlet, and a pump to force an electrolyte through the core.

Abstract:

A method and apparatus for converting ASCII path names to parsed path name structures provides downward compatibility so that program modules written for modern operating systems which provide parsed path name structure inputs may be run under older operating systems which provide ASCII path name inputs. The method includes, in its most basic form, the steps of converting the prefix and file name of an ASCII path name to a unicode string, then converting the unicode string to a parsed path structure. In a preferred embodiment of the invention, the method is implemented in compiled object code written in the "C" computer programming language. The object code defines a parsed path structure, allocates buffers for stack variables, creates various pointers for scanning and counting functions, determines whether or not Uniform Naming Convention is used for the ASCII path name, converts the ASCII code to a unicode string, and then via scanning and counting, converts the first two character spaces in the unicode string to unicode numbers which indicate total string length and prefix length, respectively, and converts every other backslash character within the unicode string to a unicode number which identifies the length of the name component of the string which follows that particular number.

International Classification:

G06F 1730

US Classification:

395621

Abstract:

Handle-based finding operations for search operations in an operating system in a computing system are converted into non-handle-based finding operations. The invention is responsive to a program module performing search operations specifying a file search path and has a find first module, a find next module and a find close module. The find first module, in response to a find first call from the program module, locates a search block for use in storing file identification information for a first file in the file search path. The find first module marks the search block as "in use," generates a handle identifying the search block and passes the handle back to the program module. The find next module is responsive to a find next call containing the handle. The find next module converts the handle into a search block address and locates the search block from the search block address. The search block is used to store the file identification information for a next file in the file search path.

International Classification:

G06F 1730

US Classification:

707104

Abstract:

Methods and computer program products are disclosed for improving the performance of hardware and software in which checking for duplicates on a linked list is required. In one form, a linked list is checked in its entirety for the presence of duplicates. In another, an element to be added to the linked list is checked to determine whether a duplicate of that element exists on the linked list.

International Classification:

Abstract:

In a computing system, debug flags for software development, testing, and debugging of a module of the operating system are retrieved and set. The module under development is provided with a debugging message handler and a lookup table of debugging flags. The table maps the debugging flags to memory locations containing the present state of the flags. A debugging message is generated at the application-level by a user desiring to monitor or alter the state of the debugging flags. The debugging message handler decodes the debugging message using the table, and the module reports or alters the debugging flag accordingly. In this manner, real-time program evaluation and control can be achieved without the conventional debugging software packages.
