Filed:

Oct 19, 1994

Appl. No.:

8/325858

Inventors:

Jerome M. Kurtzberg - Yorktown Heights NY
John S. Lew - Ossining NY

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G01N 2131

US Classification:

364499

Abstract:

An apparatus, system and method are described for determining profiles of the absolute or relative concentrations of N constituent chemical components of a chemical mixture over a group of samples. For each sample a plurality of sets of concentrations is determined wherein each set has substantially the same error for corresponding to the absorption spectra measured for the composite sample. A plurality of samples of the chemical mixture are generated, for example, by removing parts of a surface sequentially. From amongst the plurality of sets of absolute or relative concentrations over the plurality of samples, a path of highest probability is determined from which profiles of each of the chemical components can be determined. The invention is applied to generating profiles of chemical constituents as material is received from a surface of a semiconductor chip to generate profiles as a function of depth into the sample.

International Business Machines Corporation - Armonk NY

International Classification:

G05D 100

US Classification:

701 1

Abstract:

A motorized wheel-chair is equipped with one or more sensors for detecting obstacles. The detection method may be either radar or sonar (or both). An on-board computer processes these echoes and presents a visual or auditory display. With the benefit of these displays, the user issues voice commands (or exerts manual pressure) to maneuver appropriately the motorized wheelchair. One or more microphones pick up the sounds of the user's voice and transmit them to a computer. The computer decodes the maneuvering commands by speech-recognition techniques and transmits these commands to the wheelchair to effect the desired motion. In addition to speech recognition for decoding commands, voice (speaker) recognition is employed to determine authorized users.

International Classification:

G01N 2125

US Classification:

436164

Abstract:

An apparatus and method are described for determining the relative concentrations of the constituent chemical components of a chemical combination. The spectral response of the composite sample, measured at a number of wavelengths. lambda. sub. i, is represented by a vector C. The relative concentration of the jth constituent is X. sub. j, and the relative concentrations of each of the chemical constituents are represented by the vector X. The vector X can be determined from the vector C by the following matrix equation: X=(A. sup. T A). sup. -1 A. sup. T C wherein the matrix A has elements A. sub. ij, which is the spectral response of the jth component at wavelength. lambda. sub. i. Since the matrix A is a predetermined set of numbers, the elements of vector X are readily determined from the above equation. Such a determination is rapid; a profile of each of the constituents X. sub.

International Classification:

G06F 945

US Classification:

717 5

Abstract:

The present invention describes a method for a one-pass parsing algorithm for generation of a Polish string that computationally defines the maximal possible parallel execution of a general class of arithmetic expressions using one operator stack and two operand stacks. This invention relaxes the assumption that in a processor, only one operation can be performed at any given time.

US Classification:

84477R

Abstract:

A visual display is provide for music associated with a theremin or, in general, any space-controlled electric instrument. The theremin is a space-controlled electric instrument that produces an output of sound corresponding to the motion of the user, without being touched by the user. The device establishes a correspondence between motion and electric signals, then between such signals and either light and sound, or just light.
