  • Publication number: 20220113750
    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.

  • Patent number: 10180350
    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.

  • Patent number: 9816857
    Abstract: A method for calculating a rate of UV radiation absorbed by a user's skin including: capturing image data of an area of the user's skin; determining a skin tone of the user's skin based on the captured image data; calculating a rate of UV radiation absorption for the determined skin tone; measuring an amount of UV radiation exposed to the user's skin; and calculating a rate of UV radiation that would be absorbed by the user's skin based on the user's skin tone and the amount of UV radiation exposed to the user's skin. The method can further comprise calculating an amount of time that the user can be exposed to the amount of UV radiation exposed to the user's skin based on predetermined criteria. The predetermined criteria can at least include an SPF level of sunscreen applied to the user's skin.

  • Patent number: 7233389
    Abstract: A method and system is disclosed for determining a flight characteristic of an object in a flight path, the flight characteristic to be determined can be the object's position while in flight, a linear velocity, a rotational velocity or an acceleration of the object. In one embodiment, the method comprises arranging a radiation source in a plane, the plane being located to intersect the flight path of the object. The radiation source irradiates the object at least at the intersection with the flight path. The object is provided with at least first and second surface features having a predetermined configuration such as, for example, equally spaced parallel lines painted on the surface of the object. Reflected radiation from the object is measured with a sensor from the surface features and a flight characteristic of the object is determined based on the measured reflected radiation and the predetermined configuration of the surface features.
