A Bluetooth receiver comprises a RF front end configured to receive a Bluetooth signal including a preamble and 34-bit pseudo-number ; a DC estimator communicatively coupled to the RF front end; and a frame synchronizer communicatively coupled to the DC estimator. When an indoor trash container seems full, people would normally press the garbage down into the container using their hands in order to create more room inside the container. The present invention also relates to a method for the production of said tube, comprising the following steps: subjecting an outer surface of the inner layer to a cementing process, subsequently applying an adhesive to the outer surface, and coating the outer surface with at least an outer layer. The piston is movably disposed within the operator housing and divides an inner volume of the operator housing into a closing chamber and a second chamber. Thus, during the operation of the compressor, the lead wires connected to both ends of the coil winding can be prevented from being damaged or short-circuited due to the vibrations and high temperature.
