Abstract: Aspects of the present disclosure include methods, apparatuses, and computer readable media for receiving at least one TP packet, computing a current data rate or an end time of a low throughput phase, determining if TP is in the low throughput phase, aggregating the at least one received TP packet or an ACK relating to the at least one received TP packet in response to determining that the TP is not in the low throughput phase, and transmitting the ACK to a sending device.

Abstract: A tensioner comprising a base defining a hole, the hole having a center C, the hole having a diameter sufficient to receive a driven pulley, a rotary arm engaged with the base by a retaining member connected to the base, the rotary arm rotatable about the center C, a pivot arm mounted to the rotary arm on a pivot, the pivot offset from center C, a first pulley journalled to the rotary arm, a second pulley journalled to the pivot arm, a torsion spring engaged between the rotary arm and the pivot arm for biasing the second pulley toward the first pulley, a damping member frictionally engaged between the base and the rotary arm, and the rotary arm defining a portion for receiving a first pulley fastener whereby a first pulley position is adjustable.
