US Patent:

54122805, May 2, 1995

Filed:

Apr 18, 1994

Appl. No.:

8/228849

Inventors:

Curtis E. Scott - Mentor OH
Vito J. Arsena - Highland Heights OH
Spiro Vamvakas - Rocky River OH
Joseph C. Oberle - Chagrin Falls OH

Assignee:

General Electric Company - Schenectady NY

International Classification:

H01J 6500
H01J 6504

US Classification:

313573

Abstract:

Disclosed is an electrodeless, low pressure gas discharge lamp. The lamp includes a vitreous envelope containing a metal vapor and an inert gas. The envelope is shaped with an external chamber for receiving an electrical excitation circuit. The excitation circuit is effective for exciting the metal vapor to emit light with electromagnetic fields that are passed through the vitreous envelope from outside, to inside, the envelope. A circuit supplies electrical power from power mains to the excitation circuit. A transparent, electrically conductive coating is disposed on the inner surface of the vitreous envelope for suppressing electromagnetic interference on the power mains. An electrically conductive coating is disposed on the outer surface of the vitreous envelope; it is capacitively coupled to the inner conductive coating, via a wall of the vitreous envelope, and is maintained at a suitable potential for suppressing electromagnetic interference on the power mains. The outer conductive coating comprises a matrix of a contiguous, inorganic, glass layer bonded to an exterior surface of the vitreous envelope, and conductive particles embedded in the matrix in a sufficiently dense manner to form a conductive coating.

International Classification:

H05B 4116

US Classification:

315175

Abstract:

A power supply for a metal halide discharge lamp includes a circuit for applying a high voltage starting pulse to the arc tube of the lamp to initiate the discharge, a glow transition current to provide power transitioning the arc tube from its glow to its run mode, and a run power supply circuit to provide continuous controlled d-c current to the arc tube.

International Classification:

H05B 4116

US Classification:

315248

Abstract:

An electrodeless, low pressure gas discharge lamp includes a vitreous envelope containing a discharge medium and being shaped with an external chamber for receiving an electrical excitation circuit. The excitation circuit is effective for exciting the discharge medium to emit light with electromagnetic fields that are generated by the excitation circuit. A circuit is included for supplying electrical power from power mains to the excitation circuit. A transparent, electrically conductive coating is provided atop the vitreous envelope and is electrically connected substantially directly to one of the power mains at any given time. A transparent, electrically insulative coating is disposed atop the electrically conductive coating, and comprises a contiguous, inorganic glass layer. The insulative coating preferably has a minimum coating thickness of at least about 3. 1 microns.

International Classification:

A61B 500

US Classification:

128695

Abstract:

Electronic apparatus is disclosed which is usable to determine the fluency of a person's speech. This apparatus may monitor a dialogue directly, may be connected to a telephone to monitor a dialogue, or may be connected to be responsive to a recording of the dialogue. The apparatus determines the number of hesitation pauses of joint silence of both persons bounded by speech uttered by the subject which pauses are in excess of a time interval in the order of one second of time. The apparatus gives an indication, either visible or audible, when the number of such pauses exceeds a presettable limit per unit of time. The apparatus may be used by the medical profession to determine in a subject the existence of present clinical coronary artery disease where the rate of such hesitation pauses is in excess of a presettable value. It may also be used by disc jockeys, sales personnel, executives, or the like. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

Abstract:

Electronic apparatus is disclosed which is usable to determine the fluency of a person's speech. This apparatus may monitor a dialogue directly, may be connected to a telephone to monitor a dialogue, or may be connceted to be responsive to a recording of the dialogue. The apparatus determines the number of hesitation pauses of joint silence of both persons bounded by speech uttered by the subject which pauses are in excess of a time interval in the order of one second of time. The apparatus gives an indication, either visible or audible, when the number of such pauses exceeds a presettable limit per unit of time. The apparatus may be used by the medical profession to determine in a subject the existence of or proneness to clinical coronary artery disease where the rate of such hesitation pauses is in excess of a presettable value. It may also be used by disc jockeys, sales personnel, executives, or the like.
