Abstract: An apparatus for improving contrast in an image captured by an imaging sensor. The apparatus including: an objective optical system positioned in an optical path of illumination light on an object; an image sensor positioned in the optical path such that light from the objective optical system is incident on the image sensor; a device having a variable transparency positioned at a focal plane of the objective optical system; and a processor configured to: detect a bright spot on the image sensor; and control the device to change a transparency of a portion of the device corresponding to the detected bright spot.

Abstract: A device including: an image sensor for imaging an object field reflected from an object to be imaged; a first objective lens for focusing a background field from the object into a concentrated energy field on a spatial frequency plane of the first objective lens; and a programmable spatial light modulator positioned in an optical path at the spatial frequency plane, the programmable spatial light modulator being programmed to display an opaque region and a substantially transparent region outside of the opaque region, the opaque region corresponding to a position of the concentrated energy field.

Abstract: A heating circuit for an energy storage device having internal surface capacitance between inputs storing electric field energy between internal electrodes that are coupled to the inputs, with one of the internal electrodes coupled to one of the inputs having characteristics of a series coupled resistor and inductor to a voltage source. The heating circuit including: a power source couplable to one input, wherein the power source provides positive and negative input currents at the input, the positive input current flows into one of the inputs and the negative input current flows out of one of the inputs; and a controller for controlling the power source to provide alternating current between the positive and the negative input currents at one of the inputs at a frequency sufficient to effectively short the internal surface capacitance of the energy storage device to generate heat and raise a temperature of the electrolyte.

Abstract: A device including: a processor being configured to: instruct an image sensor to capture first image data of a patch applied to a user's skin unprotected against an ultraviolent spectrum of radiation, the patch having a reflection coefficient in the ultraviolent spectrum; measure a first reflectance from the patch based on the reflection coefficient; determine a second reflectance from the unprotected skin adjacent to the patch based on the measured first reflectance; instruct the image sensor to capture second image data of the user's skin after application of a sunscreen; determine a third reflectance from the skin adjacent to the applied patch for the skin having the applied sunscreen based on the measured first reflectance; and determine a time extending factor for the applied sunscreen based on the second and third reflectance.
