A variable power supply is controlled to supply power at approximately a first supply level for an electronic device. The variable power supply is controlled to control a transition of the power from approximately the first supply level toward a second supply level prior to controlling the variable power supply to supply power at approximately the second supply level for the electronic device. One or more power supply controller parameters are dynamically controlled.

An apparatus for reducing pollutants in internal combustion engine emissions, particularly marine electric generator engines, includes a treatment chamber having an intake opening for receiving gaseous emissions from the engine, and an exhaust opening for exiting emissions. A perforated metal tube is disposed within the treatment chamber, and an electrode is disposed within the metal tube in spaced apart relation to the metal tube. The electrode is encircled by the metal tube so that, upon applying a voltage at a predetermined frequency to the electrode, an arc is generated across the space between the electrode and the metal tube to promote a chemical reaction reducing the concentration of pollutants. The treatment chamber is contained within a manifold, and cooled by a flow of water. A supplemental air source is connected to the treatment chamber, and a chemical substrate is disposed within the treatment chamber for promoting the chemical reaction.

A system for displaying a sequential stream of information on a single display. The system includes a computer for defining an first area on the display and for displaying a first sample of the information within the first area. The first sample represents a first segment of the information. The computer further is for displaying a second sample of the information within the first area of the display. The second sample represents a second segment of the information. The computer is further for displaying a third sample of the information within the first area of the display. The third sample represents a third segment of the information. The first segment includes the second segment and the third segment.

A video editing system comprising a computer system having a mass storage and a display, a video source, such as a video cassette recorder (VCR), camera, or optical disc player, and a video processor/controller linking the computer to the video source. The computer system functions under the direction of standard operating software and video editing software which provide the user with an interface for controlling both playback and clip editing of video information from the video source. Upon initialization of the editing system, the user is presented with at least a video window for displaying the video information, a control window for regulating playback of the video information, and a clip list window having a number of rows of edit windows organized under begin, end, and clip columns. The user controls playback of video from the video source within the video window through manipulation of standard playback direction and speed indicators. To mark a video frame in the video window as either a begin or end point of a video clip, the user clicks on the desired video frame with a mouse associated with the editing system. A small digitized version of the requested video frame is then created and attached to the cursor. This small digitized frame (SDF) can then be moved in tandem with the cursor from the video window to an edit window and released. Begin and end points of clips are created by releasing an SDF within an edit window under the appropriate column. Releasing an SDF within an edit window under the clip column causes that SDF to be entered as both the begin and end point of the clip. Numerous rows of edit windows can be created in a similar manner. When the begin and end edit windows in the same row are filled with different SDFs, the video frames between those respective points are digitized and automatically inserted into the clip column for that row in an animated form. SDFs can likewise be directly manipulated to modify the content or sequence of edit windows or to change the video frame being played within the video window.

A medical gin pole for use by patients in performing physical therapy has a collapsible construction to enable convenient portability. In an erected condition, the gin pole has an A-frame configuration formed by an elongated rectangular base and a pair of struts. Lower ends of each of the struts are frictionally engaged in spaced apertures formed in the base. Upper ends of each of the struts are pivotally mounted to a bracket. A folding brace extends between the struts and serves to retain the struts in an erected condition. A linear guide rod is pivotally mounted to the bracket for movement about a pivot axis perpendicular to the pivot axes of the strut. The linear guide rod may be extensible and terminates in a mounting plate for securement to a vertical wall surface. A carriage is formed by a hollow sleeve surrounding the rod. The carriage is mounted for reciprocal movement along the linear guide rod and a pulley is suspended therefrom. A manipulating mechanism is supported by the pulley for selectively raising and lowering limbs of a patient.

An aid for speech therapy comprising a chart having a series of time frames of equal time intervals. Each of the time frames has an illustration of the human mouth to pictorially display the lips, tongue and jaw positions of the mouth in making a sound, word or phrase alphabetically displayed in the time frames. A sound reproducing device may also be provided to audibly reproduce the sound, word or phrase which is alphabetically displayed.
