摘要： A detector for detecting a communication pulse in the presence of noise is disclosed having a transmitter for transmitting a communication pulse of carrier frequency having a main pulse portion and a pre-pulse portion, the pre-pulse portion being of substantially opposite phase to the main pulse portion, a receiver for receiving the communication pulse, a correlation signal circuit connected to the receiver for providing a correlation signal, the correlation signal having first and second slopes in response to the communication pulse, the second slope being steeper than the first slope, and a comparator connected to the correlation signal circuit for providing a pulse detection output signal when the correlation signal reaches a predetermined threshold, the threshold being set at level to detect the correlation signal at a point on the second slope.

摘要： A portable bar including an ice chest, a removable tray, and a plurality of beverage containers attached to the upper surface of the tray. The ice chest has a rim located on the interior thereof adjacent its upper perimeter edge. The removable tray is adapted to rest on the rim with either its upper or lower surface facing towards the interior of the ice chest. Each of the beverage containers has a manually operated pump dispenser removably attached thereto and providing a lid thereto. In its transportation and storage configuration, the upper surface of the tray and attached beverage containers face downwardly towards the interior of the ice chest. In its service configuration, the upper surface of the tray and attached beverage containers face upwardly.
