Abstract: A closed audio circuit is disclosed for personalized audio experience management and audio clarity enhancement. The closed audio circuit includes a plurality of user equipment (UEs) and an audio signal combiner for a group audio communication session. The UEs and the audio signal combiner form a closed audio circuit allowing a user to target another user to create a private conversation to prevent eavesdropping. The UEs receive user audio input signals and send the audio input signals to the audio signal combiner. The audio signal combiner receives the audio input signals from each UE and transfer desired mixed audio output signals to each of the UE.

Abstract: A method of using a filing cabinet device includes moving a movable divider of a filing cabinet to a desired position for placing files in front of the movable divider; providing a filing cabinet device for the movable divider including a projection that extends a distance W in front of a top of the movable divider; placing files in the filing cabinet between the movable divider and the front of the filing cabinet; and using the projection of the filing cabinet device to orient the files between the movable divider and the front of the filing cabinet so that the bottom of a rear file extends closer to the front of the filing cabinet than the top of the rear file, allowing the files to be easily identified and preventing the files from being packed too tightly together in the filing cabinet.
