A tobacco heater with straight through heating tube, comprising a housing with a replaceable battery and a control PCB board; the housing has a mouthpiece; each side of the housing is hinged with an openable seagull door; inside the door is a heating tube at the middle housing; between the mouthpiece and the tube is an airflow path; inside each door is a compress tool for blocking the tobacco; the tube is electrically connected to the board. An openable seagull door is hinged on both sides of the housing to block the tube formed on the inner side of the door in the housing middle to form a straight through tobacco heating container. Tobaccos can be quickly and easily loaded by opening the doors, and the heater can be powered on when closed doors; opening doors, the tobacco heating residues can be easily and quickly cleaned after using.

摘要:
A hybrid passive optical network (“PON”) includes a time-division multiplexing (“TDM”) optical line terminal (“OLT”) and a wavelength-division multiplexing (“WDM”) OLT. The TDM OLT communicates with a first group of customer premises (“CPs”) via TDM signals while the WDM OLT communicates with a second group of CPs via WDM signals. A remote node power splitter is coupled to receive the TDM and WDM signals and broadcast both the TDM signals and the WDM signals on all of its ports facing towards the CPs. Optical filters are disposed between the remote node power splitter and the second group of CPs. Each optical filter is configured to pass a sub-group of the WDM signals while blocking other WDM signals such that each of the second group of CPs receives its own allocation of WDM signals but does not receive WDM signals allocated to other CPs of the second group of CPs.
摘要:
Various multi-lane ADCs are disclosed that substantially compensate for impairments present within various signals that result from various impairments, such as phase offset, amplitude offset, and/or DC offset to provide some examples, such that their respective digital output samples accurately represent their respective analog inputs. Generally, the various multi-lane ADCs determine various statistical relationships, such as various correlations to provide an example, between these various signals and various known calibration signals to quantify the phase offset, amplitude offset, and/or DC offset that may be present within the various signals. The various multi-lane ADCs adjust the various signals to substantially compensate for the phase offset, amplitude offset, and/or DC offset based upon these various statistical relationships such that their respective digital output samples accurately represent their respective analog inputs.
