Abstract: A cleaning system with on-board user-training functionality may include: a cleaning machine; an electronic playback device constructed and arranged for user training, with the playback device connected to the cleaning machine; and an electronic storage unit on which one or more items of training information are stored, with the training information relating to training a user in the operation or use of the cleaning machine. In this fashion, a user may select and play training information on the playback device to train the user in the operation or use of the cleaning machine. The playback device may include play, pause, rewind, fast-forward, and stop functions, whereby a user may select an item of training information, play the item, pause or stop play of the item, and practice performing the item on or with the cleaning machine to which the playback device is connected.

Abstract: The method may include putting fresh cleaning liquid in the trolley bucket assembly bucket and the vacuum recovery tank; and, while propelling the system across hard surface flooring: dispensing fresh cleaning liquid from the bucket onto flooring by adjusting the spigot; spreading fresh cleaning liquid on flooring with the liquid spreader assembly; and vacuuming soil and cleaning liquid from flooring into the tank with the squeegee head assembly. The method may further include, when a desired amount of cleaning liquid has been dispensed from the bucket, or a desired amount of cleaning liquid has been vacuumed into the tank: stopping dispensing of cleaning liquid from the bucket; stopping propelling of the system; and transferring a desired amount of cleaning liquid from the tank to the bucket via the cleaning liquid transfer outlet. In addition, the method may include resuming propelling the system across flooring while also: dispensing; spreading; and vacuuming.

Abstract: A cleaning system may have a trolley bucket assembly, a vacuum recovery tank, and a vacuum motor assembly. The trolley bucket assembly may have a bucket, a wheeled chassis, and a spigot fluidly connected to the bucket. A user may dispense and regulate the flow of cleaning liquid from the bucket through the spigot by manually adjusting the spigot. The tank may hold cleaning liquid and soil, and may have a bottom wall, a vacuum recovery inlet, and a transfer outlet through which cleaning liquid may be transferred to the bucket for reuse. The bottom wall may have an interior surface; and the transfer outlet may have an entry opening through which cleaning liquid from the tank enters the transfer outlet. The entry opening may be positioned above a portion of the interior surface, thereby inhibiting soil that settles on the interior surface portion from passing through the transfer outlet.

Abstract: A cleaning cloth of the invention includes: a first face including a first fold location and a second fold location that intersects and is generally perpendicular to the first fold location, the first and second fold locations dividing the entire first face into four quadrant cleaning areas of substantially equal size, each of the first and second fold locations having a length; and a set of four sequential indicators at the first face, with one of each of the set of four sequential indicators located at one of each of the four quadrant cleaning areas. The first face is free of marked lines that extend along the entire length of each of the first and second fold locations. In this fashion, a user may fold and unfold the cleaning cloth so as to expose and use one or more of the four quadrant cleaning areas in a particular sequence by reference to the sequential indicators, and whereby a user may know which of the four quadrant cleaning areas have been used by reference to the sequential indicators.

Abstract: A system, method and computer readable medium which provides for the playback of a media file (e.g., audio files, video files, etc.) through a separate media organizer (e.g., Apple's ITUNES®, WINDOWS® Media Player, etc.) when the target media file is in a format that is incompatible with the media organizer (e.g., the Free Audio Lossless Codec files or FLAC format). The media file playback system generates a “proxy” pointer file that is compatible with the media organizer and prompts the system to play the incompatible media file. The proxy file comprises compressed audio comprising a length and sample rate equal to that of the media file. Advantageously, a user that would otherwise be unable to playback an incompatible file through the media organizer due to limitations of the media organizer (e.g.

Abstract: A method and system for receiving audio data, converting the audio data into discretely sampled data, such as digital audio, and transforming the digital samples into a user-controllable visual representation for computer-based data interpretation and editing. A plurality of synchronized streams of sampled data recordings are digitally sampled, segmented, and rendered into a plurality of arc segments. A value of one or more audio data parameters are determined for each arc segment. A visual indication of the parameter value, such as a color, hue, or shade, is determined for each arc segment. The plurality of arc segments are arranged into a plurality of arcs, and the plurality of arcs are arranged as a smooth, continuous radial spiral, or arcs, using graduated grays or colors to denote waveform characteristics to form a realistic visual depiction of a mechanical recording emulating a conventional “vinyl” record.

Abstract: A media file playback system, method and computer readable medium which provides for the playback of a media file (e.g., audio files, video files, etc.) through a separate media organizer (e.g., Apple's iTunes®, Windows® Media Player, etc.) when the target media file is in a format that is incompatible with the media organizer (e.g., the Free Audio Lossless Codec files or FLAC format). The media file playback system generates a “proxy” pointer file that is compatible with the media organizer and prompts the system to play the incompatible media file. Advantageously, a user that would otherwise be unable to playback an incompatible file through the media organizer due to limitations of the media organizer (e.g., the restriction against playing FLAC files through the Apple iTunes® software application), is able to execute playback using the media file playback system via interactions with the familiar and centralized interface provided the media organizer.
