An apparatus and methods for operating a frequency selective surface are disclosed. The transmitter and the receiver are coupled with the processor, for respectively transmitting and receiving the signals. Client-side portions of the object module are then downloaded to each of the clients that are participating in the electronic meeting. A gripping tool may further be coupled to one of the dispensing or recovery trays. A first oxide layer is formed over an entire surface including the lower passivation layer. After the detection of a decoder under run, the method restarts the feed of audio data to the decoder when an amount of buffered audio data is equal to or greater than a dynamically adjustable threshold amount of audio data.
