Abstract: Systems, methods, and computer-readable storage devices are disclosed for simulated choral audio chatter in communication systems. One method including: receiving audio data from each of a plurality of users participating in a first group of a plurality of groups for an event using a communication system; generating first simulated choral audio chatter based on the audio data received from each of the plurality of users in the first group; and providing the generated first simulated choral audio data to at least one user of a plurality of users of the event.

Abstract: A warp-resistant heat sink suitable for soldering to one side of a relatively fragile, ceramic semiconductor substrate comprises a plate of heat-conducting material having a plurality of slits along two sides thereof, and a plurality of U-shaped heat-conducting members each of which extends through a respective one of the slits in the plate. The U-shaped heat-conducting members are soldered to the same side of the plate, the members along one edge of the plate being off-set with respect to the members along the opposite side of the plate in order to increase the heat transfer efficiency when air is forced through the heat sink. The plate material is selected so as to have a substantially identical thermal coefficient of expansion as that of the substrate material.
