Abstract: A group video conferencing apparatus for the purposes of facilitating a video conference involving a group of participants which are azymuthly located about said apparatus is described. Means are are provided for the identification of a principle speaker and for the positioning of the video camera so as to capture the image of the principle speaker. Identification of the azymuthal orientation of the principle speaker is realized through the electronic processing of audio signals generated by the group of participants, and the azymuthal positioning of the video camera is adjusted through electromechanical means so as to capture the image of the identified principle speaker.

Abstract: A novel laser disk holder is described which permits the demounting of a laser disk that is mounted thereupon through the application of a simple one touch action. Demounting of the laser disk is achieved through the application of downward pushing force onto a center release button which has the effect of nullifying the interference fit which exists between the center opening of the laser disk and the center element onto which it is mounted upon. Resilient lifting arms then act to urge the demounted laser disk upwards and away from the top surface of the laser disk holder, thus making the laser disk available to be grasped by an individual.

Abstract: A compartment is formed from the assembly of a bottom panel, a top panel, a right side panel, a left side panel, and a rear panel. The compartment is suitably sized so as to retain a multiple number of credit cards which are inserted into the compartment through a front opening and which are arranged inside the compartment in a stack and with a same physical orientation. The cards are securely retained inside the compartment by an integrated retention clip, and the cards are extracted from the compartment by means involving an integrated notch. A money clip affixed to the compartment provides a means for the retention of foldable paper currency.
