US Classification:

717124, 717127, 717129, 717131, 714 34, 714 381, 714 3814

Abstract:

A method, computer-readable medium, and apparatus for debugging a computer program utilizing breakpoints triggered by accessing a rarely used or unused I/O port is provided. Rarely used or unused I/O ports are identified in a computer system and a debugger program is instructed to halt program execution when an access is made to one or more of the identified ports. An instruction for writing to one of the ports is then inserted in the program to be debugged. When the instruction is executed, the debugger program will cause the execution of the program to stop. When the breakpoint is no longer needed, the debugger program is instructed not to halt when an access is made to the I/O port.

US Classification:

Abstract:

Sensors based on single-walled carbon nanotubes (SWNT) are integrated into a microfluidic system outfitted with data processing and wireless transmission capability. The sensors combine the sensitivity, specificity, and miniature size of SWNT-based nanosensors with the flexible fluid handling power of microfluidic “lab on a chip” analytical systems. Methods of integrating the SWNT-based sensor into a microfluidic system are compatible with the delicate nature of the SWNT sensor elements. The sensor devices are capable of continuously and autonomously monitoring and analyzing liquid samples in remote locations, and are applicable to real time water quality monitoring and monitoring of fluids in living systems and environments. The sensor devices and fabrication methods of the invention constitute a platform technology, because the devices can be designed to specifically detect a large number of distinct chemical agents based on the functionalization of the SWNT. The sensors can be combined into a multiplex format that detects desired combinations of chemical agents simultaneously.

Appl. No.:

7/570126

Yu J. Liu - Wharton NJ

Assignee:

ITT Corporation - New York NY

International Classification:

G10L 500

US Classification:

381 42

Abstract:

A speech coder employs vector quantization of LPC parameters, interpolation, and trellis coding for improved speech coding at low bit rates (400 bps). The speech coder has an LPC analysis module for converting input speech to LPC parameters, an LSP conversion module for converting LPC parameters into line spectrum frequencies (LSP) data, and a vector quantization and interpolation (VQ/I) module for encoding the LSP data into vector indexes for transmission by applying LPC spectral amplitude as weighting coefficients to the LSP data. The VQ/I module outputs one vector index for every two LPC frames in order to reduce the transmission bit rate, and the omitted frames are interpolated on the receiving end. A decoder correspondingly decodes incoming indexes to LPC parameters and synthesizes them into output speech. Trellis coders with an adaptive tracking function encode the pitch and gain parameters of the LPC frames.

International Classification:

B01D 39/20
B01D 39/16

Abstract:

Filter media comprising non-woven fiber webs having one or more advantageous physical properties are generally described. In some embodiments, a filter media and/or non-woven fiber web described herein comprises a combination of fibers that results in enhanced physical properties. For example, the non-woven fiber web may comprise a combination of fiber types that is advantageous, such as a combination comprising fibrillated fibers, glass fibers, and/or binder fibers. In some cases, the filter media and/or non-woven fiber web comprising the combination of fibers may be formed into undulations (e.g., by a creping and/or microcreping process) to further enhance the physical properties of the filter media and/or non-woven fiber.
