A programmable light rope system is a wirelessly operated rope light assembly having an LED rope light with a programmable light controller, a transmitter, a receiver, and a remote controller. Means for directing a fluid to the transforming means from the inlet and means for analyzing the gas-phase analyte molecule to determine an identity thereof are also positioned within the case. The mobile computing device controls a transmit power level of an associated communication circuit based on whether the body presence sensor detects a body presence within proximity to the mobile computing device. The user can later ask the system to replay the generated commands, thus causing automatic creation of the reformatted digest of the changed version of the online document. The video data and associated data of each video materials which satisfy requirements inputted through an inputting means, out of the plurality of video materials from a storing means, and the reference image and associated information of each video material are displayed on a screen based on the video data and the associated data. The antenna is fed at its open end.
