Patent number: 10732030Abstract: The present invention provides methods and devices for determining end of life of a light fixture by comparing the light output of a control LED of the fixture with the light output of an illumination LED of the fixture. The control LED is energized for a short period of time for the purpose of measuring its light output. The illumination LED is energized for the duration of time of the light fixture itself. In this way, the amount of degradation of the illumination LED can be determined by comparison with the control LED. If the light output of the illumination LED falls below a threshold level, actions may be take, such as, for example, sounding an alarm.Type: GrantFiled: June 30, 2014Date of Patent: August 4, 2020Assignee: Astronics CorporationInventor: Jeffery Basil Lendaro

Patent number: 9666386Abstract: A multi-illuminated pushbutton, including a substrate having a switch and a button cap. A lighting board may be affixed to the substrate, the lighting board having a first light source, a second light source, and a through channel disposed between the first light source and the second light source. The button cap can have a first window for transmission of light from the first light source, a second window for transmission of light from the second light source, and a button base disposed through the channel of the lighting board and in operable relation with the switch. The button base can be shaped to prevent substantially all light emitted from the first light source from transmission through the second window and prevents substantially all light emitted from the second light source from transmission through the first window.Type: GrantFiled: May 5, 2014Date of Patent: May 30, 2017Assignee: Astronics CorporationInventors: Julien Touchette, Colin Dassigli

Patent number: 6066830Abstract: A process for manufacturing electroluminescent lamps using a laser beam to remove a material layer of a multi-layer material structure, in which the laser beam has a first energy level directed at a first material layer, e.g., a conductor, laid over a second material layer, e.g., an insulator/substrate. The laser beam is moved in an overlapping fashion such as spiral pattern motion across the first material layer. A part of the first material layer is sublimed exposing a region of the second material under the area where the spiral pattern was applied. Additionally, a second laser beam having a second energy level, e.g., higher than the first energy level, is moved along a path over the exposed second material layer subliming the remaining underlying layers to form the final lamp shape.Type: GrantFiled: June 4, 1998Date of Patent: May 23, 2000Assignee: Astronics CorporationInventors: Douglas Cline, Thomas Supples, George Rosenberger

Patent number: 5361017Abstract: Each of a plurality of EL lamps in an instrument panel has its own control circuit for connecting the lamp to an adjustable AC voltage source. Each control circuit includes a photodetector for detecting the intensity of the illumination of its associated lamp, when the lamp is energized. With respect to a given input voltage of the AC voltage source, when the intensity of the light emitted by a given lamp begins to diminish, its control circuit will automatically increase the AC voltage applied across the electrodes of the lamp, thereby maintaining the light intensity of the lamp regardless of its age, for a given AC input voltage to the control circuit. The intensity of each lamp therefore remains consistent throughout substantially the full life of the EL lamp.Type: GrantFiled: February 1, 1993Date of Patent: November 1, 1994Assignee: Astronics CorporationInventor: Daniel J. Krause

Patent number: 5140329Abstract: A low cost easily deployed, yet highly accurate weapon mounted trajectory analysis radar system uses optimized Doppler radar signals to detect the actual trajectory of a projectile fired from an artillery piece such as a 155 mm Howitzer. The actual trajectory data is used to determine an atmospheric model that may be used to aim the weapon for future firings. The system includes a Doppler radar system having a turret mounted antenna that tracks the projectile, a digital signal processor using a FFT to convert radar pulses to trajectory data and a data processing system that analyzes the trajectory data to develop a true atmospheric model.Type: GrantFiled: April 24, 1991Date of Patent: August 18, 1992Assignee: Lear Astronics CorporationInventors: Jeffrey D.

Patent number: 4806908Abstract: A plurality of keys are mounted in parallel columns on a key supporting panel for reciprocation between upper, inactive positions and lower, active positions. Each key comprises a translucent core having a legend on its upper end, a conductor on its lower end, and an opening therethrough intermediate its ends. Each core is mounted for reciprocation at its lower end in a plastic sleeve, which is removably mounted by a flexible detent in one of the openings in the panel, and is surrounded adjacent its upper end by a flexible sleeve or hood which resiliently urges the key core to its upper position. In each column of key cores the openings in the latter register with each other, and an elongate electroluminescent strip extends through the registering openings and beneath the panel to prevent accidental withdrawal of the keys, and to illuminate the legends on a column of keys when energized.Type: GrantFiled: May 14, 1987Date of Patent: February 21, 1989Assignee: Astronics CorporationInventor: Elliot Krupnik

Patent number: 4720080Abstract: A rigid, metal strap has a hook formed on one end and a handle on the other. The hook is disposed to be inserted between a tire rim and a surrounding, tubeless tire, only one sidewall of which (the inboard side) has been mounted on the rim. The inner, terminal end of the hook is engaged with and retains the bead on the inboard side of the tire against the circumferential flange formed on one side of the rim. An adjustable clamp on the strap is releasably clamped to the opposite side of the rim to secure the strap to the rim and therefore to hold the inboard tire bead against movement. A turnbuckle is pivotally mounted at one end on the strap adjacent its handle and has a hook on its opposite end engageable with the outboard bead of the tire, so that by adjusting the turnbuckle the outboard side of the tire can be spread away from the rim.Type: GrantFiled: February 12, 1987Date of Patent: January 19, 1988Assignee: Astronics CorporationInventor: Mason C. Winfield

Patent number: 4662419Abstract: Nearly circular, generally C-shaped beadlocks, which are made from a generally rigid plastic material, are slightly flexible so that they can be inserted within a tubeless tire and snugly around the annular central section of a supporting tire rim of either the split rim or drop center variety. The confronting ends of the C-shaped beadlocks are secured together by releasable clips, which function to prevent the ends of the beadlock from separating during use at high speeds or at low speeds in run flat operation. At least certain embodiments of the beadlocks have a plurality of spaced ribs projecting from each side thereof to engage and retain the beads of a tire against dislodgment of a rim.Type: GrantFiled: February 6, 1986Date of Patent: May 5, 1987Assignee: Astronics CorporationInventor: Mason C.

Patent number: 4578617Abstract: The weight of an electroluminescent instrument panel is substantially reduced by manufacturing it from a pair of complementary plastic shells, which are molded together by a potting compound. The front shell of the panel is made by vacuum drawing a sheet of plastic over a first die plate, which forms in the back of the sheet a central recess, which has therein a plurality of rearwardly projecting, hollow bosses, and which is surrounded by a shallow overflow trough. One or more EL lamp elements are placed in the central recess with registering openings therein positioned over and surrounding the rearwardly projecting bosses, after which a potting compound is poured into the central recess to cover the EL elements. The complementary rear or back shell, which is also vacuum formed over a second die plate, is then forced into the back of the front shell, thereby causing excess potting material to flow out of the central recess in the front shell and into the surrounding overflow trough.Type: GrantFiled: November 7, 1983Date of Patent: March 25, 1986Assignee: Astronics CorporationInventors: Charles Kerr, III, Mark Forell
