  • Patent number: 9106815
    Abstract: A system for acquiring images includes a photographing machine. The photographing machine includes a base, a carrier coupled to the base, a camera coupled to the carrier, a camera positioning system, and a background panel coupled to the carrier. The camera can take photographs of an object when the object is in a target zone. The camera positioning system moves the carrier to position the camera and to point the camera at the target zone. When the carrier is moved to position the camera, at least a portion of the background panel moves such that at least a portion of the background panel maintains a position opposite the camera relative to the target zone.

  • Patent number: 8688061
    Abstract: A system and method for biasing a power amplifier includes a power amplifier having a driver stage and an output stage, the driver stage having a plurality of driver devices, a bias current source configured to deliver a bias current to each of the plurality of driver devices, and a current directing element configured to receive the bias current and selectively bias each of the plurality of driver devices based on a reference voltage and a system voltage.

  • Patent number: 8676045
    Abstract: Disclosed are various embodiments of a studio arrangement and a method of capturing images and/or video. One embodiment of the disclosure includes a front light source aimed at a background, an image capture position located between the background and the front light source, an elevated platform positioned between the image capture position and the background, and at least one rear light source positioned between the elevated platform and the background. A subject can be photographed and/or filmed on the elevated platform to achieve a desired effect of a substantially seamless background where a rear edge of the elevated platform is imperceptible to an image capture device positioned at the image capture position.

  • Patent number: 8477832
    Abstract: A power detector includes a first phase shift element implemented to shift a phase of a first input signal to generate a first phase-shifted signal, a second phase shift element implemented to alter a phase of a second input signal to generate a second phase-shifted signal, a combiner for combining the first phase-shifted signal and the second phase-shifted signal to generate a combined single-phase signal, and a single element power detector for determining a power of the combined single-phase signal.
