US Patent:

20130342371, Dec 26, 2013
Filed:

Jun 26, 2012
Appl. No.:

13/533491
Inventors:

Jagdish T. Madhav - Bothell WA, US
International Classification:

G08B 5/36
B23P 11/00
F21V 17/00
B60Q 1/00
G08B 21/18
US Classification:

340945, 3406911, 340457, 29428, 29464
Abstract:

The present disclosure provides a directionally filtered indicator light, wherein a directional filter is applied to a light source that is controlled to emit light when a condition or series of conditions are met. The directional filter, in turn, regulates the transmission of light from the light source so that a first group of individuals, located within a viewing angle, are the only individuals able to see the transmitted light. In one example, the directionally filtered indicator light of the present disclosure allows an indicator light on the interior of a passenger aircraft to be viewed from outside the aircraft in direct sunlight while substantially eliminating the presence of transmitted light from a passenger seating area.

US Patent:

44646810, Aug 7, 1984
Filed:

Apr 15, 1982
Appl. No.:

6/368619
Inventors:

Norman A. Jacobs - Arlington Heights IL
Jagdish T. Madhav - Morton Grove IL
Assignee:

Teletype Corporation - Skokie IL
International Classification:

H04N 110
US Classification:

358285
Abstract:

A facsimile document scanner 10 is illustrated which includes an optical system 23 having a folded optical path 40 and an adjustable lens system 42. A test pattern 60 in the form of a plurality of alternate light and dark stripes 64, 66 is focused upon a linear photodiode array 50 mounted in an integratd circuit pack 51. The number of light and dark stripes 64, 66 is equal to the number of photodiodes in the linear photodiode array 50 across the document width. For adjustment purposes, an oscilloscope 70 is connected to a serial output from the integrated circuit pack 50 and the position of the lens system along the optical path 42 is adjusted and a corresponding adjustment is made to the pointer of the lens holder 45 within the lens housing 43 to obtain the desired image size and focus. The position of the diode array 50 is adjusted with respect to the focused image 72, 74 to obtain the maximum display amplitude.

US Patent:

20210383775, Dec 9, 2021
Filed:

Jun 3, 2020
Appl. No.:

16/891915
Inventors:

- Chicago IL, US
Jagdish T. Madhav - Bothell WA, US
International Classification:

G09G 5/377
G06T 7/70
H04N 5/225
H04N 5/247
H04N 7/18
Abstract:

Apparatus, systems, and methods for providing a rearward view of an aircraft. The system, apparatus, and methods include one or more cameras disposed on an aft portion of a fuselage of the aircraft, a heads-up display is within a cockpit of the aircraft, and a heads-up control. The heads-up control receives image data from the one or more cameras and generates an image on the heads-up display based on the image data from the one or more cameras to provide a rearward view of an area behind the aircraft. The heads-up control may be configured to determine when an aerial object is within a predetermined range behind the aircraft and responsively generate the image on the heads-up display based on the image data from the one or more cameras to provide a rearward view of an area behind the aircraft in which the aerial object is located.
