Patent number: 11927773Abstract: A liquid lens comprising: a lens body including a cavity, a control electrode, and a common electrode; a first liquid disposed within the cavity and in electrical communication with the common electrode; a second liquid disposed within the cavity; an insulating layer in contact with the first liquid and the second liquid and separating the first liquid and the second liquid from the control electrode; and a driver driving a voltage differential across the common electrode and the control electrode, with the first liquid resisting current flow between the common electrode and the control electrode and thereby raising a temperature of the first liquid from a current temperature to a predetermined temperature, which is higher than the current temperature. The driver raises the temperature of the first liquid from the current temperature to the predetermined temperature by increasing a frequency of a voltage waveform of the voltage differential.Type: GrantFiled: March 19, 2019Date of Patent: March 12, 2024Assignee: CORNING INCORPORATEDInventors: Ian Armour McKay, Dragan Pikula, Dean Michael Thelen

Publication number: 20240060851Abstract: A method, system, and computer program product for determining a core-to-ferrule offset of a ferrule for a fiber optic connector. A reference ferrule is physically aligned with a core imager by positioning the reference ferrule so that edges of the reference ferrule in a plurality of profile images are aligned with fiducial markers in the images. The reference ferrule is incrementally rotated about its longitudinal center access, a core image captured at each rotational angle, and a reference core-to-ferrule offset determined based on the core images. A test ferrule is physically aligned with the core imager by positioning the test ferrule so that edges of the test ferule are aligned with the edges of the reference ferrule in a plurality of profile images. The core-to-ferrule offset of the test ferrule is then determined based on an offset between the test and reference cores in a composite core image.Type: ApplicationFiled: November 2, 2023Publication date: February 22, 2024Inventors: David Matthew Berg, Christine Cecala, Sterling Michael Clarke, Richard Hagan, Stefan Wolfgang Kramel, David Andrew Pastel, Dragan Pikula, Michael Brian Webb, Elvis Alberto Zambrano

Patent number: 11822100Abstract: Control systems for liquid lenses can use feedback control using one or more measured parameters indicative of a position of the fluid interface in the liquid lens. Capacitance between a fluid and an electrode in the liquid lens can vary depending on the position of the fluid interface. Current mirrors can be used for making measurements indicative of the capacitance and/or the fluid interface position. The liquid lens can be calibrated using the measurements indicative of capacitance and/or fluid interface position as the voltage is driven across an operational range. A control system can use pulse width modulation (PWM) for driving a liquid lens, and a carrier frequency for the PWM signals can be varied to control power consumption in the liquid lens. The slew rate can be adjustable to control power consumption in the liquid lens.Type: GrantFiled: April 5, 2018Date of Patent: November 21, 2023Assignee: CORNING INCORPORATEDInventors: Jann Paul Kaminski, Raymond Miller Karam, Dragan Pikula, Daniel Ohen Ricketts

Patent number: 11662568Abstract: A liquid lens system includes first and second liquids disposed within a cavity. An interface between the first and second liquids defines a variable lens. A common electrode is in electrical communication with the first liquid. A driving electrode is disposed on a sidewall of the cavity and insulated from the first and second liquids. A controller supplies a common voltage to the common electrode and a driving voltage to the driving electrode. A voltage differential between the common voltage and the driving voltage is based at least in part on at least one of: (a) a first reference capacitance of a first reference electrode pair disposed within the first portion of the cavity and insulated from the first liquid or (b) a second reference capacitance of a second reference electrode pair disposed within the second portion of the cavity and insulated from the first liquid and the second liquid.Type: GrantFiled: November 14, 2018Date of Patent: May 30, 2023Assignee: Corning IncorporatedInventors: Jann Paul Kaminski, Raymond Miller Karam, Ian Armour McKay, Dragan Pikula, Thomas M Wynne

Patent number: 11567242Abstract: A liquid lens can be coupled to ground, such as to impede charge from building up in the liquid lens during operation thereof. For example, an electrode that is in electrical communication with a conductive fluid of the liquid lens can be coupled to ground. A switch can be used to selectively couple the liquid lens to ground, such as for discharging the liquid lens. An electrode can be selectively coupled to ground and to driving signals using a switch. In some cases, drive signals can be provided to electrodes other than the grounded electrode for driving the liquid lens. In some cases, the liquid lens can be driven using feedback control based on one or more measured parameters indicative capacitance between a fluid and one or more electrodes in the liquid lens.Type: GrantFiled: November 15, 2018Date of Patent: January 31, 2023Assignee: Corning Incorporated/LG Innotek Co.

Patent number: 9807722Abstract: Components, systems, and methods for determining propagation delay of communications in distributed antenna systems are disclosed. The propagation delay of communications signals distributed in the distributed antenna systems is determined. If desired, the propagation delay(s) can be determined on a per remote antenna unit basis for the distributed antenna systems. The propagation delay(s) can provided by the distributed antenna systems to a network or other system to be taken into consideration for communications services or operations that are based on communications signal delay. As another non-limiting example, propagation delay can be determined and controlled for each remote antenna unit to uniquely distinguish the remote antenna units.
