Appl. No.:

17/757578

Inventors:

- Cleveland OH, US
Fatima Sophia Emami - Canoga Park CA, US
John David McCall Shearer - Pittsburgh PA, US
Maria Christina Baker - Los Angeles CA, US

Assignee:

PPG Industries Ohio, Inc. - Cleveland OH

International Classification:

G02F 1/1335
H01J 31/20
G02B 5/20
H01L 27/32
C07D 487/04

Abstract:

A display screen assembly is provided comprising a blue light protection transparency. The transparency comprises an additive, such that the blue light protection transparency blocks greater than 50% of light of a wavelength range of 380 nm to 418 nm from passing through the blue light protection transparency as measured by ultraviolet-visible spectroscopy; and the blue light protection transparency blocks 20% to 45% of light of a wavelength range of greater than 418 nm to 430 nm from passing through the blue light protection transparency as measured by ultraviolet-visible spectroscopy. Additionally, the blue light protection transparency has a total visible light transmittance greater than 65% as measured according to ASTM D1003-07 Procedure B.

John McCall - Rancho Cucamonga CA, US

International Classification:

G01R 15/14
G01R 31/08

Abstract:

A dynamic real time transmission line monitor, a dynamic real time transmission line monitoring system, and a method of dynamic real time transmission line monitoring are provided. A dynamic real time transmission line monitor includes a housing installable on a transmission line, the housing including a base portion and a cover portion; at least one sensor configured to sense in real time at least one of a temperature, a position, a current, an acceleration, a vibration, a tilt, a roll, or a distance to a nearest object, the at least one sensor including a radar sensor configured to sense a distance to a nearest object; and an antenna in the cavity of the housing and configured to transmit a signal including information sensed by the at least one sensor away from the monitor in real time.

International Classification:

H02J 13/00
G01K 13/00
G01S 17/08
G01R 19/00

Abstract:

A system and method for determining a reliability line rating for a transmission line is disclosed. In response to a line clearance measurement and a line temperature measurement received from a transmission line monitor coupled to a transmission line, the system generates a temperature-clearance model for the transmission line based on the received line clearance measurement and line temperature measurement. The system generates a plurality of past dynamic line ratings and determines a scaling factor based on the plurality of past dynamic line ratings. The system then generates a dynamic line rating for an interval of time in the future and scales the dynamic line rating in response to the scaling factor to obtain a reliability line rating for the interval.
