Abstract: A popcorn eliminator device used to remove the popcorn design from the ceilings is disclosed. A popcorn eliminator device for scraping and cleaning comprises a vacuum head, a main scraper blade, a front scraper blade, an adaptor, a plastic collection tube and a connection hose and a shop vacuum. The adaptor connects the plastic collection tube using a connection hose to a heavy-duty shop vacuum. The popcorn eliminator device is flipped over and applied to the ceiling using a pushing motion and the front scraper blade is pressed into the slot in the front lip of the vacuum head, thereby scraping near the wall at the end of each pass. The popcorn eliminator device simultaneously collects the debris in the vacuum head resulting in the intake of debris by the vacuum.

Abstract: A computer implemented application development (authoring) system permits objects (such as VBX custom controls) to be graphically inserted into the program under development by dragging and dropping associated icons into one of four views. The properties associated with the object may then be assigned settings. Development of a complete application is accomplished by visually arranging, ordering, and interconnecting the objects without the necessity of writing any code. The four views of Output, Map, Multitrack, and Workform may be synchronized so that changes made to the program in one view are simultaneously reflected in all other views. The system generates as output a script listing the objects and their properties which is then executed by a separate run time program. The system permits use of objects written to a standard specification and the addition at any time of additional objects written to that.

Abstract: A system for automatically detecting the presence of a train located within a detection or surveillance area of a railroad track associated with a railroad grade crossing. The system includes a transmitter unit that transmits a detection signal. The system also includes a receiver that receives a detection signal. A receiver unit receives one or more signals. A processor coupled to the receiver unit is configured to process the received signals and determine the presence, absence or movement of a train or signal within the detection or surveillance area. The processor unit is configured to initiate an action when the processor determines the presence or the absence of the train or one or more detection signals. The current invention also includes a method for automatically detecting the presence of the train located within a surveillance area associated with a railroad grade crossing area.

Abstract: A computer system for scheduling events between end users of the system. Each end user is granted a unique password protected personal calendar. This calendar is generated from information stored in a database at a central server, and delivered to each end user as standard HTML sent through the Internet. This custom personal calendar is then viewed by the end user in a standard Web Browser. This obviates the need for special software programs to be purchased by end users, and also allows end users of any CPU type to read their calendars. When an end user uses the system to send an Invitation or Announcement to others on the system, the sending end user has the option of sending Email in addition to posting that information in the calendars' of others. When an end user sends an Invitation or Announcement to a person who is not an Appointnet user, then the Appointnet system automatically creates a unique calendar for the recipient, and sends and Email to that person.
