A juice extraction module for a juicer is provided, which includes a container formed with a juice discharge port, a sieve positioned inside of the container, a screw positioned inside of the sieve to extract juice from a material, and a lid coupled to a top end of the container and formed with a input port through which the material is input. The first headphone jack is electronically and selectively connected to the first mode chip or to the second mode chip through the switch. The igniter may also have at least one electrode extending into the pre-combustion chamber. A coarse tilt control is performed on the lens according to the tilt compensation when the lens is within the far-field region. Furthermore, the agricultural implement includes a fluid joint coupled between the first and second flexible ends and configured to provide a sealed connection between the first and second flexible ends during relative pivotal movement of the first and second tool bars in operation but to allow for uncoupling of the first and second flexible ends for servicing of the implement. More specifically, techniques are described for utilizing a \u201cperfect hash\u201d function to implement an associative cache within a computing device.
