In one embodiment, a Television receiver to perform a method of synchronizing a demodulator at a Viterbi decode input in the TV receiver using one or more bit de-interleaved even and odd Orthogonal Frequency Division Multiplexing symbols is provided. The optical transceiver includes a control module and a persistent memory. There is a rope member made from a second predetermined material and having each of a second predetermined diameter and a predetermined length. A time may be selected by one of the devices to synchronously play the particular media content on the multiple devices based on a user availability calendar accessible through each of the devices. Comparators are used to compare the output voltage of the operational amplifier with a first reference voltage to raise the supply voltage of the operational amplifier, if clipping is imminent. Also provided is a pharmaceutically acceptable composition comprising a compound of Formula I, or a pharmaceutically acceptable salt thereof.
