Abstract: A method and system of publishing datafile and metafile images over a network connection. A user can use a web page to transmit the name of a datafile to the server hosting the peak viewing program. The server then processes the information, launches Chromview to generate the metafiles, then uses a series of HTML pages to display the information in a .PNG image file of the datafile on the user's computer screen. This page would have the datafile image, as well as information about the datafile (as applicable), such as the list of available ions, and start/stop times. The user could select an ion, or a start/stop time, and the resulting picture for the datafile would be displayed on his screen. The user can enlarge chosen areas of chromatograms and fragmentograms by entering values in text boxes or by clicking on two opposite corners of the selected area. The user can use either remote (Internet) or local (intranet) means to access the datafiles.

Abstract: A mechanism is provided for deploying a wheelchair ramp at the door of a vehicle, especially a bus, the ramp being of the kind which rotates between a stowed position at which it is flush with the vehicle floor and a deployed position in which it slopes downwardly and outwardly from the vehicle. The mechanism provides a "float down" feature which permits the ramp to move downward under gravity without the need for operator control and prevents crushing of obstacles that get in the downward path of the ramp. The mechanism includes a transmission for translating a single hydraulic cylinder stroke into more than 180.degree. of rotation of the ramp.
