A hinged glass article includes wings including glass and a hinge positioned between the wings. The wings fold about the hinge. The hinge includes a glass portion integrally joined to the wings and a polymer portion overlaying the glass portion. The glass portion of the hinge includes a first surface facing away from a second surface thereof. The polymer portion overlays the first surface. The glass portion of the hinge is asymmetric (with the wings unfolded) such that halves of the glass portion of the hinge do not mirror one another about a lengthwise middle of the hinge. Also, the first surface of the glass portion of the hinge is free of small inclusions impinging thereupon that have a linear cross-sectional dimension extending fully thereacross and through a center thereof greater than 2 μm and less than 30 μm.

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.

Self-heating liquid lens and self-heating methods for the same

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.

Liquid lens control systems and methods

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.

Liquid lenses and methods for operating liquid lenses

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.

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. In this manner, the location of a client device communicating with a remote antenna unit can be determined within the communication range of the remote antenna unit.

The optical touch system includes a transparent sheet having a surface, at least one light source and at least one detector which are operably arranged relative to the transparent sheet to transmit light through the sheet and to detect the transmitted light. Performing position sensing using the capacitive touch system simplifies the pressure-sensing optical touch system.

An optical touch screen that utilizes a planar transparent sheet and that is configured to determine the position of a touch event on the transparent sheet is disclosed. Light-source elements and light-sensing elements are operably disposed at the transparent sheet perimeter. Light is detected over lines-of-sight between the light-source elements and the light-sensing elements. Attenuated lines-of-sight due to a touch event are determined. Polygons are established by overlapping triangles defined by the limiting lines of sight for each light-sensing element. Polygons with attenuations below the attenuation threshold are eliminated. The centers of the remaining polygons are then determined to establish the locations of the touch events. The systems and methods provide robust detection of multiple touch events.

Optical systems operable to emit an output beam having fast-switched wavelengths are provided. In one embodiment, an optical system includes a laser and a wavelength conversion device. The laser emits a pump beam that switches between at least two fundamental spectral peaks at different wavelengths at a wavelength cycling period that is shorter than a response time of the human eye. The wavelength conversion device includes a non-linear optical medium configured to phase match the frequency doubling of the at least two switched fundamental spectral peaks such that an output beam that switches between at least two frequency-converted spectral peaks at different converted-wavelengths is emitted from an output facet of the wavelength conversion device when the pump beam of the optical source is incident on an input facet of the wavelength conversion device.

Wavelength-switched optical systems

Start-up methods for frequency converted light sources and projector systems comprising frequency converted light sources are described herein. The start-up methods generally comprise modulating the frequency converted light source over three degrees of freedom (two spatial dimensions and one wavelength dimension). Specifically, fast oscillation of an axis of an adjustable optical component is performed simultaneously with fast oscillation of a wavelength of the semiconductor laser while a second axis of the adjustable optical component is incrementally stepped and the output intensity of the frequency converted light source is monitored for each step. This start-up method allows for three linear searches to be used to rapidly locate the appropriate control settings for the frequency converted light source.
