US Patent:

8479238, Jul 2, 2013

Filed:

May 14, 2002

Appl. No.:

10/146300

Inventors:

Edward Y. Chen - Holmdel NJ, US
David Crawford Gibbon - Lincroft NJ, US

Behzad Shahraray - Freehold NJ, US

Assignee:

AT&T Intellectual Property II, L.P. - Atlanta GA

International Classification:

H04N 5/445
H04N 7/173

US Classification:

725 86, 725 39, 725 40, 725 44, 725 88

Abstract:

A system and method are provided for content-based non-linear control of video data playback. A multimedia database having multimedia data including multimedia content data is searched based on a user query to determine a first set of multimedia data. The multimedia data includes indexes to and condensed representations of corresponding video data stored in a video database. A portion of the first set of multimedia data is displayed at a control device in response to the user query. A user of the control device selects an element of the first set of multimedia data for video playback and video data corresponding to the element delivered to a video device for playback. A user of the control device selects an element of the first set of multimedia data for additional information and a second set of multimedia data corresponding to the element delivered to the control device.

Jan 23, 1981

Appl. No.:

6/228039

Inventors:

William A. Thornton - Cranford NJ
Daniel A. Larson - Cedar Groove NJ
Edward Chen - Glen Rock NJ

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

H01J 6118
H01J 6148

US Classification:

313227

Abstract:

High-intensity-discharge lamp of the mercury-metal halide type efficiently illuminates objects with excellent color appearance. The arc tube filling comprises the usual inert, ionizable starting gas and mercury in predetermined amount as required to provide a predetermined operating voltage drop between the lamp electrodes. The metal halide filling substantially comprises a predetermined limited amount of thallous iodide, a predetermined limited amount of stannous iodide and a predetermined limited amount of calcium iodide. The stannous iodide is used in such amount that it serves primarily to enhance the emission of the calcium iodiode and the amount of stannous iodide is sufficiently limited to curtail the generation of the characteristic continuous tin emission. The calcium iodide is present in greater gram amount than the tin iodide so that the effects of the calcium iodide emission are predominant. The resulting discharge has its emission concentrated in three selected wavelength portions of the visible spectrum, namely, blue violet which is due primarily to the calcium iodide emission, green which is due to the thallium iodide emission, and red which is due to the tin-iodide-enhanced calcium iodide emission.

International Classification:

G01J 350

US Classification:

356406

Abstract:

Method and apparatus for expressing as a number the relative brightness of artificial illumination as it is perceived by the average observer. There is extracted (i. e. , detected) from the illumination to be measured, a blue-appearing narrow band, a green-appearing narrow band, a yellow-appearing narrow band and a red-orange-appearing narrow band. From these extracted bands are generated six different signals: a signal expressed as (aB) where (a) is about 0. 23 and (B) is the watts of energy in the blue band, a signal expressed as (bG) where (b) is about 0. 97 and (G) is the watts of energy in the green band, a signal expressed as (cR) where (c) is about 0. 33 and (R) is the watts of energy in the red-orange band, a signal expressed as (dY) where (d) is about 0. 19 and (Y) is the watts of energy in the yellow band, a signal expressed as (eG) where (e) is about 0. 25 and (G) is the watts of energy in the green band, and a signal expressed as (fR) where (f) is about 0.

Abstract:

Techniques for deterministic switch microscopy include resolving at least one nitrogen vacancy center in a diamond structure. A magnetic field can be applied across the diamond structure and the nitrogen vacancy centers can be optically excited. The nitrogen vacancy centers can be switched from a dark state to a bright state or a bright state by a dark state by applying at least one microwave pulse. A fluorescent response of each nitrogen vacancy center can be detected and a nitrogen vacancy center can be resolved based on the fluorescent response of each nitrogen vacancy center as it corresponds to the orientation of the nitrogen vacancy center relative to the applied magnetic field.
