Abstract: Described are systems and methods for extracting parameters associated with a look/beauty aesthetic presented in a content item such as an image or a video. The extracted parameters can be used to identify beauty products that can be used to create a similar look/beauty aesthetic and to render the beauty product on a streaming live-feed video of the user so that the user can assess how the product looks on the user. Aspects of the disclosure also relate to classifying content items presenting a look/beauty aesthetic based on a dominant skin tone present in the content item.

Abstract: The measurement of solar irradiance measurement have important applications, including solar resource assessment, solar power plants, photovoltaic system monitoring, heating and cooling loads of buildings, climate modeling and weather forecasting. An option to establish this is to solely measure the global horizontal irradiance and employ an irradiance decomposition algorithm to derive direct normal irradiance and diffuse horizontal irradiance. However, these models vary in complexity and generally have a relatively high uncertainty particularly between latitudes +60° N and ?45° S these errors which includes large portions of North America, Europe, Russia, and Asia where the applications are centered.

Abstract: Solar spectral irradiance (SSI) measurements are important for solar collector/photovoltaic panel efficiency and solar energy resource assessment as well as being important for scientific meteorological/climate observations and material testing research. To date such measurements have exploited modified diffraction grating based scientific instruments which are bulky, expensive, and with low mechanical integrity for generalized deployment. A compact and cost-effective tool for accurately determining the global solar spectra as well as the global horizontal or tilted irradiances as part of on-site solar resource assessments and module performance characterization studies would be beneficial.

Abstract: A content server generates an ad review display that allows users to review previously-presented ads. The content server provides a stream of media content to a client device for presentation to a user of the client device, and generates an ordered list comprising ad tiles corresponding to ads presented to the user with the stream of media content. The content server generates an ad review display based on the ordered list. The ad review display comprises one or more ad tiles organized along a first axis of the ad review display according to their position in the ordered list. The content server sends the ad review display to the client device for presentation to the user. Responsive to receiving a request to replay a previously-presented ad from the client device, the content server inserts the ad into the stream of media content being provided to the client device.

Abstract: A trailer hitch storage apparatus including a rectangular base plate, a hollow rectangular male member having a first front end welded to the base plate, and a hollow rectangular female member having a second front end welded to the base plate. The male member is removably disposed within a trailer hitch receiver which receives an open first rear end of the male member. A ball mount is removably disposed within the female member through a second rear end. A right portion of a pin is slidably and continuously disposed through a first pair of openings disposed through the female member and a second pair of openings disposed through the ball mount. A left portion of a pin is slidably and continuously disposed through a first pair of apertures disposed through the male member and a second pair of apertures disposed through the trailer hitch receiver.

Abstract: A concentrator photovoltaic module that has a secondary optical element that has alignment features that cooperate with alignment feature of a solar cell assembly to self-align the secondary optical element with the solar cell. The secondary optical element is secured directly to the backplate or to the solar cell assembly. The secondary optical element is spaced-apart from the solar cell, which avoids shear stress between the secondary optical element and the solar cell.

Abstract: This severe storm “Storm Safe Hurricane Shelter” is designed as a hexagon shaped vessel that has superior strength to protect the occupants from the elements during peak storm danger. It is fabricated from 3/16? plate aluminum and only has 2 major different parts. The six side panels and 12 end pieces are designed and fabricated to allow for storage in a very small place close to the use area. In its non-assembled state it will take very little room and be completely concealable to people outside of you and family members. The shelter is assembled, by the user, with the 8 mm fasteners supplied, along its edges every 6?. It is sealed at each seam with special putty.

Abstract: Various apparatus and methods of supplying regulated battery power to an electrical device, such as a downhole tool, are provided. In one aspect, a method of providing power to an electrical device is provided that includes providing a plurality of batteries and providing a plurality of controllable regulators for regulating the power output of the plurality of batteries. The plurality of controllable regulators is set so that power is drawn from a minimum number of the plurality of batteries necessary to satisfy demand from the electrical device. The electrical device is enabled to periodically draw power from and thereby depassivate each of the plurality of batteries.

Abstract: A signal amplifier system for use in a downhole logging system wherein a signal transmitter is mounted in a sonde suspended on a logging cable thousands of feet into a borehole. Variable slew rate amplifiers connected to a differential amplifier are set forth. Preferably, programmable amplifiers having a gain determined by a driving current are used. Two such amplifiers are connected to the input signal, and they are driven by different current sources. The output signals are summed at a differential amplifier. Through the use of different slew rates, the incoming signal is amplified by the two programmable amplifiers and the outputs of the two amplifiers are then subtracted from one another. Signals which pass equally through both programmable amplifiers (due to slew rates which do not cause limiting) thus are subtracted from each other.

Abstract: For use with a down hole logging system equipped with a logging cable having two wires therein, the preferred and illustrated embodiment sets forth a system which conducts electrical power and telemetry signals along a two wire logging cable. AC power is generated at the surface for transmission to a power consuming load in the sonde. This AC supply has a specified frequency, there also being data gathering equipment in the sonde which forms an AC telemetry signal transmitted up the two wire logging cable. This disclosure is directed to an improvement in the telemetry drive circuitry which maintains the isolation between power flow and signal flow. The circuitry incorporates FET output transistors, transformer coupled, to provide the necessary output signal and isolation.
