Abstract: Devices and methods for evaluating at least one photograph during a photography session are described. In some instances, a camera may be used to capture images during a photography session and a computing device may be used to identify a portrait order specification for the photography session including a set of required photographs, each having associated required criteria. The computing device may evaluate the images and determine whether the images can be associated with any of the required photographs based on features included in the images being associated with the required criteria of the required photographs. The images associated with required photographs may be displayed, and a determination of whether the images qualify as a required photograph may be made using a graphical user interface, or may be made automatically.

Abstract: A method and device for generating a composite group image from subgroup images is provided. Subgroup images, each having a common background, are accessed. The boundaries of a subgroup area within each of the subgroup images is determined. At least one horizontal and at least one vertical shift factor is determined using the determined boundaries. An arrangement for the subgroup images based on the at least one horizontal and the at least one vertical shift factor is generated. The composite group image is generated by blending the subgroup images arranged in the arrangement.

Abstract: A pole unit including a vacuum interrupter switch having a fixed contact extending into one end of a vacuum chamber and being electrically coupled to a first terminal, and a moving contact extending into an opposite end of the chamber. A sliding contact is rigidly coupled to the moving contact and slidably coupled to a second terminal. The pole unit also includes an electromagnetic actuator including a coil, a rod coupled to the sliding contact and a spring positioned against the rod. The pole unit further includes a transmitter coil and a receiver coil that are electromagnetically coupled, where the receiver coil is electrically coupled to the actuator and is electrically isolated from the transmitter coil. In this configuration, the interrupter switch, the actuator and the receiver coil are at a line potential and the transmitter coil is at ground potential.

Abstract: A treat dispenser includes a body having an exterior surface and a recess in the body. The recess has an outlet and is defined by interior surface having first and second lips protruding into the recess. The first lip defines a first treat-holding position having a first depth relative to the outlet, and the second lip defines a second treat-holding position having a greater second depth relative to the outlet.

Abstract: A method of illuminating a subject during photography is disclosed. The method includes illuminating a background lighting system during a first image capture, illuminating a subject lighting system during a second image capture, and illuminating the background lighting system during a third image capture. The time from the first image capture to the third image capture is less than about 100 milliseconds. Also disclosed is a method for generating a composite mask of a subject, including receiving the three images, determining any movements of the subject between the first and third images, estimating an intermediate position of the subject during the second image, and generating a composite mask at the estimated intermediate position.

Abstract: Compositions and methods for cleaning, disinfection, sterilization, and decontamination of surfaces and objects are provided. In particular, a hyperprotonation composition is described that comprises a surfactant, one or more emulsifiers, a biocide, and a weak acid and is effective to disrupt both the microbial biofilm defenses as well as the microbes within. Methods of applying the hyperprotonation compositions to contaminated surfaces, equipment, fabrics, food, and human or animal tissue to disrupt the microbial biofilms and eradicate the microbes within are also disclosed.

Abstract: Low noise amplifiers (LNAs) with output limiting are provided herein. In certain implementations, a gallium nitride (GaN) LNA includes LNA amplification circuitry and an output limiter that is connected to an output of the LNA amplification circuitry and operable to limit an output power of the GaN LNA. By limiting the output signal power, a number of benefits are achieved, including protection of downstream circuitry receiving the GaN LNA's output signal. For example, such downstream circuitry can be fabricated using silicon or other fabrication technology associated with a lower signal power handling capability relative to that of the GaN LNA.

Abstract: A photographic scene replacement system includes a photographic scene with a detectable pattern. The system operates to capture a digital photograph of a subject and the photographic scene having the detectable pattern with a digital camera when the subject is arranged between the digital camera and the photographic scene. The system also operates to process the digital photograph at least in part by automatically detecting the detectable pattern in the digital photograph, to distinguish the subject from the photographic scene in the digital photograph.
