Abstract: 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.

The method involves generating a computational model that includes a fluid-filled lens (103) and the shape of a cornea causes deformation of an internal structure of the fluid-filled lens (103) to generate a deformed, fluid-filled lens (103) with altered optical properties. The method also includes modelling (5) the optical properties of the deformed, fluid-filled lens (103). The shape of the fluid-filled lens (103) is then adjusted (7) to reduce the effects of the deformation on the optical properties. This is referred to as an adjusted fluid-filled lens (103). A corresponding off-eye lens design is generated (110 based on the adjusted fluid-filled lens design.

Abstract: A system for generating a series of reducing intensity laser pulses from an ultrafast pulsed laser source. The reducing intensity series of pulses is equally temporally spaced between pulses from the laser source. The repeating series of reducing intensity laser pulses is fed to a microscope for imaging. The microscope is capable of detecting the fluorescence from a sample generated by each pulse in the series. The data is processed using knowledge of the pulse intensity, location on the test sample, and amount of fluorescence measured to create an increased dynamic range of the image relative to what can be obtained in a normal two-photon imaging system.

Abstract: In a door mirror device for a vehicle, when a driving body is moved rotationally towards an upper side, a gear plate is moved towards a lower side so that urging force applied from a coil spring to the driving body is decreased. In contrast, when the driving body is moved rotationally towards the lower side, the gear plate is moved towards the upper side so that the urging force applied from the coil spring to the driving body is increased. As a result, it is possible to reduce a difference between a load that is applied in order to move the driving body rotationally towards the upper side and the load that is applied in order to move the driving body rotationally towards the lower side.
