  • Publication number: 20170229595
    Abstract: A system for collecting light energy through smaller photovoltaic cells (PV cell) such that the length of the PV cell is much greater than the width. The PV cells may be linear strung together and placed within a recess of a frame or pan that is part of a PV module. The PV module includes a lens and waveguide which provide advantages for focusing and concentrating the light energy by positioning a waveguide over the smaller PV cell and engaging the PV cell with a lens such that the lens is held by the frame.

  • Patent number: 6971882
    Abstract: An interactive karaoke system includes a microphone developing an audio input from at least one karaoke performer; a camera producing a series of video frames including the at least one karaoke performer; and a karaoke processor system including a video environment and a related audio environment for the karaoke performer. The karaoke processor system is coupled to the camera to create extracted images of the at least one karaoke performer from the series of video frames and to composite the extracted images with a background derived from the video environment. The video environment is affected by at least one of a position and a movement of the at least one karaoke performer. A karaoke network includes a local area network, a local karaoke server coupled to the local area network and storing local karaoke content; and a number of karaoke systems coupled to the local area network, each of which can request karaoke content from the local karaoke server.
